DETAILED DESCRIPTION

Please refer to FIG. 3 and FIG. 4. FIG. 3 and FIG. 4 are schematic diagrams of a speaker fastening mechanism 50 in different states according to a preferred embodiment of the present invention. The speaker fastening mechanisms 50 are disposed on two sides inside a casing 54 of an audio device 52. The audio device 52 can be a LCD TV, a lap-top PC, and so on. Numbers and positions of the fastening mechanisms 50 installed inside the audio device 52 are not limited to the embodiment and depend on practical design demand. One of the fastening mechanisms 50 will be introduced in the following. Please refer to FIG. 5. FIG. 5 is a perspective diagram of the casing 54 of the audio device 52 according to the preferred embodiment of the present invention. The speaker fastening mechanism 50 includes a first fastening component 56 installed inside the casing 54. A first hole 561 is formed on the first fastening component 56, and a first breach 5611 is formed on a side of the first hole 561. Protrusions 57 are respectively disposed on two sides of the first breach 5611 of the first fastening component 56. The speaker fastening mechanism 50 further includes a second fastening component 58. The second fastening component 58 is installed inside the casing 54 and disposed on a side of the first fastening component 56. A second hole 581 is formed on the second fastening component 58, and a second breach 5811 is formed on a side of the second hole 581. Protrusions 60 are respectively disposed on two sides of the second breach 5811 of the second fastening component 58. Furthermore, a direction of the first breach 5611 can be substantially perpendicular to a direction of the second breach 5811. In other words, the structure of the first fastening component 56 and the structure of the second fastening component 58 can be identical, but the positioning direction of the first fastening component 56 and the positioning direction of the second fastening component 58 are different. Thus, design of an identical component is applied to reduce cost of manufacture and management.

The speaker fastening mechanism 50 further includes a speaker unit 62, a first elastic component 64, and a second elastic component 66. Please refer to FIG. 6 and FIG. 7. FIG. 6 is an exploded diagram of the speaker unit 62, the first elastic component 64, and the second elastic component 66 according to the preferred embodiment of the present invention. FIG. 7 is an assembly diagram of the speaker unit 62, the first elastic component 64, and the second elastic component 66 according to the preferred embodiment of the present invention. The speaker unit 62 is for converting audio signals into sound waves. A first fixing part 621 and a second fixing part 622 are formed on the speaker unit 62. In this embodiment, the first fixing part 621 and the second fixing part 622 are openings respectively. The first elastic component 64 is wedged in the first fixing part 621 of the speaker unit 62 and fastened inside the first hole 561 of the first fastening component 56 through the first breach 5611. The first elastic component 64 includes a first washer 641 installed on a side of the first fixing part 621 when the first elastic component 64 is wedged inside the first fixing part 621 of the speaker unit 62. The first elastic component 64 further includes a first gasket 642 for clamping the speaker unit 62 with the first washer 641 when the first elastic component 64 is wedged inside the first fixing part 621 of the speaker unit 62. The first elastic component 64 further includes a second gasket 643 for clamping the first fastening component 56 with the first gasket 642 when the first elastic component 64 is wedged inside the first hole 561 of the first fastening component 56. Since the first elastic component 64 is made of resilient material, interference generated between the first elastic component 64 and the first fixing part 621 of the speaker unit 62 as well as the first breach 5611 of the first fastening component 56 causes elastic deformation of the first elastic component 64 when the first elastic component 64 is wedged inside the first fixing part 621 of the speaker unit 62 and fastened inside the first hole 561 of the first fastening component 56 through the first breach 5611, so as to fix the first elastic component 64 with the speaker unit 62 and the first fastening component 56 tightly. Besides, the protrusion 57 of the first fastening component 56 can contact against the first elastic component 64 to constrain the first elastic component 64 inside the first hole 561 when the first elastic component 64 is wedged inside the first hole 561 of the first fastening component 56, so as to avoid the first elastic component 64 from loosing or falling from the first breach 5611 while being turned over. Furthermore, the first elastic component 64 can be made of rubber material, and the first washer 641, the first gasket 642, and the second gasket 643 of the first elastic component 64 can be integrated monolithically.

The structure of the second elastic component 66 is identical to the first elastic component 64. The second elastic component 66 is wedged in the second fixing part 622 of the speaker unit 62 and fastened inside the second hole 581 of the second fastening component 58 through the second breach 5811. The second elastic component 66 includes a second washer 661 installed on a side of the second fixing part 622 when the second elastic component 66 is wedged inside the second fixing part 622 of the speaker unit 62. The second elastic component 66 further includes a third gasket 662 for clamping the speaker unit 62 with the second washer 661 when the second elastic component 66 is wedged inside the second fixing part 622 of the speaker unit 62. The second elastic component 66 further includes a fourth gasket 663 for clamping the second fastening component 58 with the third gasket 662 when the second elastic component 66 is wedged inside the second hole 581 of the second fastening component 58. Since the second elastic component 66 is made of resilient material, interference generated between the second elastic component 66 and the second fixing part 622 of the speaker unit 62 as well as the second breach 5811 of the second fastening component 58 causes elastic deformation of the second elastic component 66 when the second elastic component 66 is wedged inside the second fixing part 622 of the speaker unit 62 and fastened inside the second hole 581 of the second fastening component 58 through the second breach 5811, so as to fix the second elastic component 66 with the speaker unit 62 and the second fastening component 58 tightly. Besides, the protrusion 60 of the second fastening component 58 can contact against the second elastic component 66 to constrain the second elastic component 66 inside the second hole 581 when the second elastic component 66 is wedged inside the second hole 581 of the second fastening component 58, so as to avoid the second elastic component 66 from loosing or falling from the second breach 5811 while being turned over. Furthermore, the second elastic component 66 can be made of rubber material, and the second washer 661, the third gasket 662, and the fourth gasket 663 of the second elastic component 66 can be integrated monolithically.

The assembly process of the speaker fastening mechanism 50 is introduced as follows. First of all, the first elastic component 64 is wedged in the first fixing part 621 of the speaker unit 62 and the second elastic component 66 is wedged in the second fixing part 622 of the speaker unit 62. Afterwards, the first elastic component 64 is fastened inside the first hole 561 of the first fastening component 56 through the first breach 5611, and a side of the speaker unit 62 can be fixed to the first fastening component 56, as shown in FIG. 3. Then, the speaker unit 62 can be rotated so that the second elastic component 66 on a unfixed end of the speaker unit 62 rotates to be fastened inside the second hole 581 of the second fastening component 58 through the second breach 5811. As shown in FIG. 4, two ends of the speaker unit 62 are fixed to the first fastening component 56 and the second fastening component 58 respectively, and the assembly process of the speaker fastening mechanism 50 is finished. Since an end of the speaker unit 62 is fastened to the first fastening component 56 by the first elastic component 64 and then another end of the speaker unit 62 rotates to be fastened to the second fastening component 58 by the second elastic component 66, the speaker fastening mechanism 50 of the present invention can fasten the speaker unit 62 without screws. Furthermore, the direction of the first breach 5611 of the first fastening component 56 is not identical to the direction of the second breach 5811 of the second fastening component 58, for achieving biaxially constraining the speaker unit 62, so as to prevent the speaker unit 62 from loosing or falling, and to improve the assembly speed and yielding rate greatly.

In contrast to the prior art, the rotary speaker fastening mechanism of the present invention can fasten the speaker unit biaxially without screws. It has advantages of convenient assembly and without affecting by assembly tolerance so as to increase assembly efficiency of the speaker unit.
