  • Patent number: 10277984
    Abstract: Disclosed is a multi-strand independent input-output voice coil. The voice coil is a potted coil, which is formed by winding in the following steps: a. forming a multi-strand flat cable by synchronizing and juxtaposing at least two enameled wires; b. winding the multi-strand flat cable to form the potted coil, each enameled wire including independent current input and output ends; and c. under the control of an ICE chip, forming, by the enameled wires together, a multiple-input multiple-output electrical connection end to correspond to vibration drive control of sounds at different frequencies separately. During use, the independent current input and output ends of the enameled wires reduce impact of inertia in vibration of a vibrating diaphragm and impact of a frequency and current on a sound during a change in a volume or tone.

  • Patent number: 10264385
    Abstract: An optimal listening position for the multi-channel audio sound system is determined. A listening area and other audio playback controls may also be defined or modified by a listener. During subsequent audio playback, an imager captures images of at least a portion of the listener. When the listener has moved to a position that is different from a previous position, one or more audio parameters are adjusted for at least one channel in the multi-channel audio system in order to reposition the initial or previous optimal listening position to the current position of the listener. When the listener moves outside the listening area, an out of bounds response is initiated to disable or control the audio playback until the listener moves to a position within the listening area.
