AUTOMATIC SWITCHER FOR SOUND CHANNEL

摘要

An automatic switcher for a sound channel comprises a three-dimensional sensor (5), a processor (6), a channel switching module (8), and an audio signal source (7). The three-dimensional sensor (5) obtains a current posture of the automatic switcher for a sound channel and transfers a signal to the processor (6). The processor (6) controls the channel switching module (8) to allocate a left sound channel and a right sound channel of the audio signal source to loudspeakers of four different channels. The automatic switcher for a sound channel is capable of automatically switching sound channel output to adapt to a change of the posture, so as to enable a left loudspeaker to output a left sound channel, and a right loudspeaker to output a right sound channel. The sound effect actually felt by a user is still that a loudspeaker located at the left hand outputs sound of the left sound channel and a loudspeaker located at the right hand outputs sound of the right sound channel, so as to ensure the consistency of directions of sound when a device rotates in any direction.
