The application mainly aims at application scenes that a plurality of sound boxes are adopted for multi-channel audio playing, such as 5.1 sound channels, 7.1 sound channels and the like. The multi-channel audio playing system is generally composed of a center speaker and a plurality of standard speakers, and can also comprise a subwoofer, so that more real stereo surround sound is provided for users, and the hearing experience of the users is improved.
A plurality of audio amplifiers in traditional multichannel audio playback system, like wireless audio amplifier, need the position that the user put each wireless audio amplifier manually to and for each wireless audio amplifier configuration sound channel, complex operation, and because the user is not professional, can't learn accurate or best placement position, if the sound channel configuration has the mistake or when placement position is not good enough, will influence user's sense of hearing experience.
Fig. 1 is a schematic diagram illustrating a channel configuration scenario of an audio playback system according to an embodiment. As shown in fig. 1, the audio playing system 100 includes a center speaker 110 and a plurality of standard speakers 120, such as wireless speakers, and fig. 1 illustrates 2 standard speakers 120 as an example, after a user puts each standard speaker 120, each standard speaker 120 is paired or bound with the center speaker 110, such as paired by bluetooth or bound by a wireless network, and before use, a sound channel needs to be configured for each standard speaker 120, such as manual configuration.
In order to improve convenience of sound channel configuration, an embodiment of the present application provides a sound channel automatic configuration strategy based on sound pressure, and the main process is as follows: sending out a section of audio signal through a transmitting terminal, such as the center speaker 110, receiving the audio signal based on a receiving terminal, such as any one of the standard speakers 120, and further configuring sound channels for each of the standard speakers 120 based on the intensity of the received audio signal, taking 4 standard speakers 120 as an example, the sound channels of each of the wireless speakers from large to small according to the intensity of the received audio signal are: a front left channel, a front right channel, a rear left surround channel, and a rear right surround channel.
Because the intensity of the audio signal is mainly determined by the distance between the receiving end and the transmitting end, when the user places each standard sound box 120, if the placement is not proper, the distance between the front right standard sound box 120 and the rear left standard sound box 120 and the center sound box 110 is equal, or the distance between the rear left standard sound box 120 and the center sound box 110 is smaller than the distance between the front right standard sound box 120 and the center sound box 110, or the user directly places one of the standard sound boxes 120 behind the center sound box 110 due to lack of professional knowledge when placing, which will cause the sound channel configuration error of the sound box, thereby providing an erroneous sound field for the user and imaging the hearing experience of the user.
In order to improve the accuracy of the sound channel configuration of the wireless sound box of the multi-channel audio system, the display device comprising the middle sound box realizes the accurate positioning of each wireless sound box based on wireless signals through the controller, so that the position coordinates of each wireless sound box are obtained, the sound channel of each wireless sound box is automatically configured based on the position coordinates of each wireless sound box, the coordinates are adopted to replace the distance in the prior art, and the accuracy of the sound channel configuration is effectively improved.
