Embodiment Construction

[0039] Below in conjunction with accompanying drawing. The present invention will be further described.

[0040] Such as figure 1 As shown, a wireless multi-channel audio system of the present invention includes a center speaker 1 and four wireless ultrasonic speakers 2 . Among them, the box of the center speaker 1 is strip-shaped, and placed in front of the user experience position 3, and the four wireless ultrasonic speakers 2 are respectively placed in the left front, right front, left rear and right of the user experience position 3. rear. The bottom of the wireless ultrasonic speaker 2 is equipped with an electric pan-tilt base.

[0041] Wherein, a DSP control chip is arranged in the center speaker 1, and a left microphone 11 and a right microphone 12 are arranged symmetrically on both sides of the bar-shaped box of the center speaker. These two microphones simultaneously collect the audio signal sent by the wireless ultrasonic speaker 2, and feed back the collected a...

Abstract

The invention discloses a wireless multi-channel sound system and a sound channel automatic calibration method thereof. The wireless multi-channel sound system comprises a middle sound box and a plurality of wireless ultrasonic sound boxes with electric pan-tilt bases. A DSP control chip and a microphone array are arranged in the middle sound box; when automatic calibration is performed on channel, a distance measurement command is sent to each wireless sound box in sequence through the DSP control chip; the microphone array feeds back collected ranging commands to the DSP control chip to be processed, the direction of sound transmission is sequentially calculated, the DSP control chip matches sound channels for the wireless ultrasonic sound boxes according to data in all directions, and finally the DSP control chip controls the wireless ultrasonic sound boxes to adjust the deflection angles of the wireless ultrasonic sound boxes. By adopting the scheme, a user does not need to distinguish the originally defined sound channel of each wireless sound box to place, and after the sound system is started, the sound system can automatically identify the position of each wireless sound box and match the corresponding sound channel for the wireless sound box, so that the user can obtain correct surround sound information.

Description

technical field [0001] The invention relates to the technical field of audio systems, in particular to a wireless multi-channel audio system and an automatic channel calibration method thereof. Background technique [0002] The 5.1-channel surround sound effect is a relatively perfect sound solution at present, which can meet the super requirements of computer games and home audio-visual. The 5.1-channel audio equipment should include: left front speaker, right front speaker, left rear speaker, right rear speaker, center speaker, and a subwoofer. These five channels are independent of each other. Among them, the ".1" channel is a specially designed subwoofer channel. [0003] At present, in the traditional 5.1-channel audio system, the left front speaker, right front speaker, left rear speaker, and right rear speaker are defined to match fixed channels at the factory, so when installing , the corresponding speaker must be placed to the preset position and adjusted to a sui...
