US10812912B2 Speaker with dual diffuser
An improved loudspeaker is disclosed. The speaker includes at least one permanent magnet, an electromagnet and a diaphragm. The diaphragm has an inner portion (active portion) and an outer portion (stabilizing portion) that are both typically ring-shaped. The interaction between the magnets causes the inner portion to move back and forth according to the electrical signal inputted. As the inner portion moves forward, the outer portion tends to move backward relative to the inner portion. The movement of the active portion tends to produce corresponding forces on the stabilizing portion that cause the stabilizing portion to move and create sound in a symbiotic fashion. In certain embodiments, the portions move relative to each other as sound is produced so that a relatively constant volume of air is displaced on either side of the diaphragm thus minimizing acoustic distortion. The inner portion may be connected to the outer portion via a hinge and/or flexible material which allows the portions to move relative to each other.

An electrical input signal applied to the moveable coil may cause motive force to be applied the rigid structure according to the input signal, so that the rigid structure moves orthogonally relative to the magnets as driven by the input signal. In this manner, the high-efficiency motor may be incorporated into a system that may reproduce a full-range audio signal. Various other methods, systems, and computer-readable media are also disclosed.

Thus, coded video data obtained from the coding operation may include temporal prediction references between frames of the video sequence.

In particular, if the signaled one of the supported partitioning patterns specifies a subdivision of the block into two or more further blocks, a removal of certain coding parameter candidates for all further blocks, except a first further block of the further blocks in a coding order, is performed. Particularly, those coding parameter candidates are removed from the set of coding parameter candidates for the respective further block, the coding parameters of which are the same as coding parameters associated with any of the further blocks which, when being merged with the respective further block, would result in one of the supported partitioning pattern.
