Abstract: This application provides a speaker control method and device, terminal equipment and a computer-readable storage medium. The method includes: obtaining a user perception-prohibited area corresponding to a target audio signal while detecting an audio output event, where the target audio signal is output in response to the audio output event; determining a first speaker based on the user perception-prohibited area, and determining a reverse cancelling sound wave corresponding to the target audio signal; generating a first control parameter based on a characteristic attribute of the reverse cancelling sound wave; and controlling the first speaker to output the reverse cancelling sound wave based on the first control parameter.

Abstract: A system for transmitting an audio signal in a vehicle includes a stabilizer located at a source position in the vehicle. At least one speaker is operatively connected to the stabilizer. The speaker is adapted to transmit an audio signal to a target position for at least partially supporting a spatial audio representation. The target position and the source position are independently movable. The stabilizer is adapted to direct the audio signal such that a trajectory between the target position and the source position is maintained regardless of respective motion of the target position and the source position. The trajectory includes a first segment between the source position and a deflecting surface and a second segment between the deflecting surface and the target position.

Abstract: A system for automatically adjusting a volume of a loudspeaker includes a loudspeaker and a processor. An infrared sensor, which generates a sensing signal when sensing IR radiation from a heat-radiating source, is disposed on the loudspeaker. The sensing signal provides a size information commensurate with a size of the heat-radiating source. The processor receives a plurality of the sensing signals at different time points to obtain a plurality of corresponding size information, realizes a change of distance between the heat-radiating source and the loudspeaker according to a change of the size information, and generates a volume-adjusting signal according to the change of distance between the heat-radiating source and the loudspeaker. The volume-adjusting signal is transmitted to the loudspeaker to adjust the volume of the loudspeaker accordingly.
