说明书全文 | The disclosure relates to the field of sensing technology, and particularly to a motion sensing apparatus and a mobile terminal. A corresponding reaction caused by the influence of external motion is referred to as motion sensing. At present, the motion sensing technology is widely used, for example, in TV remote controls, electric vehicles, computers, game consoles and mobile terminals (e.g., mobile phones). At present, the mobile terminal is no longer a simple communication terminal, in addition to the traditional voice communicating function, functions like music playing, video playing, recording, taking photographs and video, and internet surfing make the mobile terminal fashionable and highly entertaining. Producing a fashionable and entertaining mobile terminal has been a trend in the mobile terminal development. Therefore, how to make the mobile terminal more practical, fashionable and attractive has become a key factor that mobile terminal manufacturers need to consider in the market competition. As the multimedia technology continues to develop, it has become a trend that the motion sensing technology is applied to the mobile terminal. At present, when mobile terminal users want to change background pictures or play the next song, most of them have to change them manually, which is more rigid to operate without novelty, and fails to stimulate the user's desire to buy mobile terminals. However, the mobile terminal with the screen-shaking function developed by motion sensing technology leads the way for a new market. This mobile terminal has a screen shaking function, when the user needs to change in a certain function, it can be realized by gently shaking the mobile terminal. By replacing traditional manual operation with this method, it is possible to increase the practical and fashionable uses of the mobile terminal. At present, the main principle of the mobile terminal with screen shaking function is that the function of screen shaking is realized depending on a sensor system consisting of a gravity sensor or an acceleration sensor and a hardware processing circuit. One sensing signal is generated by the sensor system by sensing the shaking operation of a user, the hardware processing circuit in the sensor system performs amplification, filtering and the like processes on the sensing signal, and then outputs a processing signal. The processor in the mobile terminal detects the processing signal output by the sensor system when necessary, and performs corresponding screen shaking processes according to the processing signal. Since the sensor system needs to perform amplification and filtering processes on the sensing signal, it not only makes the hardware circuit of the sensor system more complex, but also increases the production cost of the mobile terminal. At the same time, electric energy stored in the mobile terminal will also be consumed when these hardware processing circuits process the sensing signals, which reduces the endurance capability and the reliability of the mobile terminal to some extent. In view of the deficiency in the prior art, the disclosure provides a motion sensing apparatus and a mobile terminal. The apparatus simplifies a hardware circuit to some extent, saves production cost, and reduces the consumption of electric energy. Compared with the conventional mobile terminal, the mobile terminal simplifies the hardware circuit to some extent, reduces the production cost of the mobile terminal, and improves the endurance capability and the reliability of the mobile terminal. In order to solve the above technical problem, the disclosure adopts the following technical schemes: A motion sensing apparatus includes a sensing module and a processing module, wherein the sensing module includes at least two outputs, the processing module includes at least two signal ports, each signal port of the processing module is connected with one of the outputs of the sensing module respectively; and the sensing module outputs sensing signals from different outputs according to sensed different motions, and the processing module performs corresponding processes according to the sensing signals received from different signal ports. In one embodiment of the disclosure, one end of the connector is fixedly connected with the signal source end, while the other end of the connector is correspondingly in contact with one output of the sensing module under different motions sensed by the sensing module. In one embodiment of the disclosure, the connector includes a rotation axis, the other end of the connector is rotatable around the rotation axis so as to rotatably contact one output of the sensing module under the different motions sensed by the sensing module. In one embodiment of the disclosure, the connector includes a location unit, a reset unit and a communication unit; the communication unit is connected with the location unit via the reset unit, and the communication unit is shifted from an original position relative to the location unit to be in contact with one output of the sensing module and the signal source end under the different motions sensed by the sensing module, and makes the output in communication with the signal source end, and the reset unit is configured to restore the shifted communication unit to the original position. In one embodiment of the disclosure, the location unit is a sensing cavity, and the reset unit is a spring. In one embodiment of the disclosure, the location unit is a sensing cavity including a buffer wall, the connector includes two of the communication units, the two of the communication units are located on both sides of the buffer wall respectively and connected to the buffer wall via the reset unit, and the reset unit is a spring. In one embodiment of the disclosure, the communication unit is a conductive metal sheet. The disclosure also provides a mobile terminal, which includes the motion sensing apparatus arranged in the mobile terminal, the apparatus includes a sensing module and a processing module, wherein the sensing module includes at least two outputs, the processing module includes at least two signal ports, each signal port of the processing module is connected with one of the outputs of the sensing module respectively; and the sensing module outputs sensing signals from different outputs according to sensed different motions, and the processing module performs corresponding processes according to the sensing signals received from different signal ports. As the above technical schemes are adopted, the beneficial effect of using the disclosure is that: the motion sensing apparatus consists of some simple components, thereby simplifying the hardware circuit to some extent, saving the cost, and reducing the consumption of electric energy. At the same time, a mobile terminal with the screen shaking function can be produced by applying the motion sensing apparatus to the mobile terminal. Since the sensing module and the processing module in the motion sensing apparatus replace the sensor system consisting of a gravity sensor, a lateral acceleration sensor and a hardware processing circuit in the prior art, the hardware circuit is simplified to some extent, and the production cost of the mobile terminal is reduced compared with the existing mobile terminals. By sensing the user's different motions with the sensing module, sensing signals are generated, the processing module performs corresponding processes directly according to the sensing signals. Compared with the existing sensor system, electric energy consumed by hardware processing circuit is reduced, thereby also improving the endurance capability and the reliability of the mobile terminal to some extent.
The disclosure is described below in detail through specific embodiments in conjunction with accompanying drawings. The motion sensing apparatus provided by the disclosure can be applied to the mobile terminal so as to realize the screen shaking function of the mobile terminal. Certainly, the motion sensing apparatus can also be applied to electric vehicles, game consoles and other electronics. The motion sensing apparatus provided by the disclosure includes two main parts, i.e., the sensing module and the processing module. The sensing module includes at least two outputs, the processing module includes at least two signal ports, each signal port of the processing module is connected with one of the outputs of the sensing module respectively; and the sensing module outputs sensing signals from different outputs according to sensed different motions, and the processing module performs corresponding processes according to the sensing signals received from different signal ports. In one embodiment, the sensing module includes a signal source end and a connector. The sensing signals are generated in the following way: when the sensing module senses different motions, the corresponding output communicates with the signal source end via the connector so that the output communicating with the signal source end outputs the sensing signals. The processing module performs corresponding processes according to the sensing signals received. The signal source end is a grounding end, and the sensing signals are negative pulse signals. It can be understood that the main function of the signal source end is to provide a signal source. The signal source can be selected arbitrarily, i.e., can be selected as a high level, a low level, as well as a zero level. In one embodiment of the disclosure, the selected signal source is a zero level, i.e., the selected signal source end is a grounding end, and correspondingly the generated sensing signals are negative pulse signals. In one embodiment, one end of the connector of the motion sensing apparatus is fixedly connected with the signal source end, while the other end of the connector is in contact with one output of the sensing module under different motions sensed by the sensing module correspondingly so as to make the output in communication with the signal source end. Certainly, the other end of the connector is in contact with different outputs of the sensing module in many ways, for example, in one embodiment of the disclosure, the connector includes a rotation axis, the other end of the connector is rotatable around the rotation axis so as to rotatably contact one output of the sensing module under the different motions sensed by the sensing module, thereby making the output of the sensing module in communication with the signal source end. Certainly, in one embodiment, in order to connect the connector with the output of the sensing module better, the connector is generally provided with a location unit, the main function of which is to fix the connector. In one embodiment, the connector of the motion sensing apparatus includes a location unit, a reset unit, and a communication unit. The communication unit is connected with the location unit through the reset unit; the communication unit is shifted from an original position relative to the location unit to be in contact with one output of the sensing module and the signal source end under the different motions sensed by the sensing module to make the output of the sensing module in communication with the signal source end. The reset unit is mainly configured to restore the deviated communication unit to the original position. The communication unit can be a conductive metal, or other components with conductive function can also be selected. The reset unit can be a spring, or other spring devices with reset function can also be selected. The location unit can be a sensing cavity, or other location devices with location function can also be selected. For example, in one embodiment, the location unit is a sensing cavity including a buffer wall, the connector includes two of the communication units, the two of the communication units are located on both sides of the buffer wall respectively and connected to the buffer wall via the reset unit. The main reason that a buffer wall is arranged in the sensing cavity is that the buffer wall is configured to absorb the impact force of the conductive metal to restore the conductive metal to the original state rapidly. The application of motion sensing apparatus on the mobile terminal is taken as an example below for illustration. As shown in In the embodiment as shown in The motion sensing apparatus shown in When the conductive metal sheet is located on the side wall of the sensing apparatus, and the user shakes the mobile terminal up and down or turns the mobile terminal upside down, the motion sensing apparatus within the mobile terminal performs the following operations: When the user turns the mobile terminal upside down, the metal connecting rod 4, due to its own gravity, will disconnect from the conductive metal sheet 5 with the help of the rotation axis 10, and is in turn brought into contact with the conductive metal sheet 8. Since the conductive metal sheet 2 is connected to the ground 9 via the signal line 3, the conductive metal sheet 8 conducts with the conductive metal sheet 2 at this time, the conductive metal sheet 8 is also connected to the ground, the signal line 7 connected with the conductive metal sheet 8 will output a ground signal to the external processor, so that a corresponding detection pin of the processor generates a negative jump pulse output signal, and then the corresponding detection pin of the processor detects the negative pulse signal and generates a corresponding interrupt signal, thereby performing corresponding screen shaking process. When the user turns the mobile terminal upside down again, the metal connecting rod 4, due to its own gravity, will disconnect from the conductive metal sheet 8 with the help of the rotation axis 10, and is brought into contact with the conductive metal sheet 5 again, and therefore the conductive metal sheet 5 conducts with the conductive metal sheet 2, the signal line 6 connected with the conductive metal sheet 5 outputs a ground signal to the external processor, so that a corresponding detection pin of the processor generates a negative jump pulse output signal, and then the corresponding detection pin of the processor detects the output signal and generates a corresponding interrupt signal, thereby performing corresponding screen shaking process. It can be seen that, if the user shakes the mobile terminal up and down alternately or turns the mobile terminal upside down alternately, the metal connecting rod 4 is brought into contact with the conductive metal sheet 8 and the conductive metal sheet 5 respectively so that the signal line 7 and the signal line 6 respectively output the ground signals to the corresponding detection pins of the external processor in a short time. In one embodiment, the user may shake the mobile terminal up and down when the user wants to adjust the volume, the signal line 7 and the signal line 6 respectively output the ground signals to the external processor in a short time. Since the processor receives two shaking signals output by the signal line 7 and the signal line 6 in a short time, the processor may only process the signal output by the signal line 7, and ignore the signal output by the signal line 6 or only processes the signal output by the signal line 6, and ignores the signal output by the signal line 7. Thus, the processor correspondingly detects the pin and generates an interrupt signal according to the signal output by the signal line 6 or signal line 7, invokes a corresponding application subprogram according to the interrupt signal, performs corresponding screen shaking process, thereby achieving the goal of adjusting the volume. From the above, the motion sensing apparatus can sense the shaking made by user on the mobile terminal in the direction of gravity very well. Certainly, the apparatus can also sense the shaking motion made by user on the mobile terminal in other directions by appropriately adjusting the position of the conductive metal sheets 5 and 8. As shown in Specifically, the conductive metal sheet 43 becomes one output of the sensing module when the conductive metal sheet 43 is connected with the processing module through a signal line 33, and the conductive metal sheet 42 becomes the other output of the sensing module when the conductive metal sheet 42 is connected with the processor via a signal line 32. The conductive metal sheet 44 is connected to the ground 35 via a signal line 34 to form one signal source end of the sensing module. The conductive metal sheet 41 is connected to the ground 36 via a signal line 31 to form the other signal source end of the sensing module. It should be noted that these two signal source ends are actually equivalent to one signal source end within the mobile terminal. The sensing cavity 55 is used as the location unit of the connector, and the springs 51, 52, 53 and 54 are used as the reset unit of the connector. The conductive metal 37 is used as the communication unit of the connector. One end of each of the springs 51, 52, 53 and 54 is connected with the sensing cavity 55 correspondingly, and the other end is connected with the conductive metal 37. When the user shakes the mobile terminal left, the conductive metal 37 will shake left, and at the same time is brought into contact with the conductive metal sheet 43 and the conductive metal sheet 44, so that the corresponding signal source end communicates with the output of the sensing module, and then outputs a negative pulse signal at the output, thereby making the corresponding detection pin of the processor generate an interrupt signal, and thus performing corresponding process according to the interrupt signal. Similarly, when the conductive metal 37 shakes right, it will also make the corresponding detection pin of the processor generate an interrupt signal, and corresponding process is performed according to the interrupt signal, thereby realizing the screen shaking function of the mobile terminal. Correspondingly, the position of conductive metal sheets forming the signal source end and the output in the embodiment shown in Certainly, it can be understood that the conductive metal and the spring shown in As shown in In Similarly, the apparatus shown in When the mobile terminal is shaken left and right, the motion sensing apparatus shown in When the user shakes the mobile terminal left, the conductive metal 21 moves left, and is finally in contact with the conductive metal sheets 26 and 22 to make the conductive metal sheet 26 in communication with the conductive metal sheet 22. Since the conductive metal sheet 22 is connected to the grounding end via the signal line 23 and outputs a ground signal, the conductive metal sheet 26 also outputs the ground signal, and therefore the signal line 25 connected with the conductive metal sheet 26 also outputs the ground signal to the external processor, causing the corresponding detection pin of the processor to generate a negative jump pulse signal, and thus generating an interrupt signal accordingly. Meanwhile, the conductive metal 21 moves right due to the effect of the spring 12, and is finally in contact with the buffer wall 13, since the buffer wall 13 is a flexible buffer material, the buffer wall can absorb the impact force caused when the conductive metal 21 moves right to achieve the goal of slowing down the speed at which the conductive metal 21 moves right, which finally restores the conductive metal 21 to the original state, and then continues the next left shaking motion. When the user shakes the mobile terminal right, the conductive metal 20 moves right, and is finally in contact with the conductive metal sheets 15 and 19 to make the conductive metal sheet 15 in communication with the conductive metal sheet 19. Since the conductive metal sheet 19 is connected to the grounding end via the signal line 18 and outputs a ground signal, the conductive metal sheet 15 also outputs the ground signal, and therefore the signal line 16 outputs the ground signal to the external processor, causing the corresponding detection pin of the processor to generate a negative jump pulse signal, and thus generating an interrupt signal accordingly. Meanwhile, the conductive metal 20 moves right due to the effect of the spring 14, and is finally in contact with the buffer wall 13, since the buffer wall 13 is a flexible buffer material, the buffer wall can absorb the impact force caused when the conductive metal 20 moves left to slow down the speed at which the conductive metal 20 moves left, which finally restores the conductive metal 20 to the original state, and then continues the next right shaking motion. The processor receives an output signal from the sensing module, and the corresponding detection pin of the processor generates a corresponding interrupt signal according to the output signal. The processor determines the source of the interrupt signal and invokes the corresponding application subprogram to perform the corresponding screen shaking process, thereby achieving the screen shaking function of the mobile terminal. Certainly, the apparatus shown in It should be noted that, the motion sensing apparatus shown in As shown in
It should be noted that, in the step of realizing the screen shaking of the mobile terminal described above, the user can perform screen shaking application such as changing the desktop background, adjusting the volume, changing the music track, and changing the video by shaking the mobile terminal. Certainly, by shaking the mobile terminal, the user also can make other functions of the mobile terminal have screen shaking characteristics, such as changing the current short message displayed, the current displayed photo, or the like. That is to say, when the user shakes the mobile terminal, the sensing module will generate a pulse signal, as long as the sensing signal generated by the sensing module can generate an interrupt signal on the corresponding detection pin of the processing module, and a corresponding application subprogram is preset for the interrupt signal, the application subprogram can then be used, to perform corresponding processes on corresponding screen shaking application. But, due to the limited dimension specification of mobile terminal hardware, several screen shaking applications commonly used by the user in daily life are usually pre-selected as subprograms, and the corresponding screen shaking application is processed through shaking the mobile terminal. It should be understood that, in preset application subprogram, the processes of the screen shaking application can be set as required, that is, processing rules described in the embodiment should not be used as the only processing mode of a method for implementing the whole mobile terminal with screen shaking function. It should be noted that, when the application subprogram processes a specific adjusting mode of screen shaking application, it should be determined firstly whether the mobile terminal is in an application state of the application currently, if the mobile terminal is in the application state of the screen shaking application currently, the application subprogram performs the corresponding screen shaking process. If the mobile terminal is not in the application state of the screen shaking application, the application subprogram does not respond. For example, if the current mobile terminal is in the application state of playing music tracks, but the processing module generates an interrupt signal by which the previous video is to be played, the application subprogram does not adjust the playing of the previous video. Additionally, in actuality, the mobile terminal is sometimes shaken, but it is not intended to change the pictures or videos etc. In order to avoid such accidental operations, a determination program for determining whether the shaking is an accidental operation can be set in the application subprogram. By using the motion sensing apparatus of the disclosure, a hardware circuit is simplified to some extent, the cost is saved, and the consumption of electric energy is reduced. The motion sensing apparatus may be applied to the mobile terminal to produce a mobile terminal with screen shaking function, which selects the sensing module and the processing module to realize the screen shaking function of the mobile terminal rather than a sensor system consisting of a gravity sensor and/or an acceleration sensor and a complex hardware processing circuit in the mobile terminal with screen shaking function. In such a way, the existing sensor system is replaced with some simple components, which not only simplifies the hardware circuit of the mobile terminal, reduces the production cost of the mobile terminal, but also improves the endurance capability and the reliability of the mobile terminal to some extent. The above is the further detailed description made to the disclosure in conjunction with specific embodiments, but it should not be considered that the specific embodiments of the disclosure are only limited to these descriptions. For one of ordinary skill in the art to which the disclosure belongs, many deductions and replacements can be made without departing from the inventive concept. Such deductions and replacements should fall within the scope of protection of the disclosure. |
