Acoustic positioning method and system based on acoustic device

Abstract

The invention provides an acoustic positioning method and system based on an acoustic device. The method includes the following steps: according to an acoustic wave signal emission instruction, the acoustic device sends a plurality of first acoustic wave signals with different frequencies and the same signal strength; the first acoustic wave signals attenuate to second acoustic wave signals during transmission, and the second acoustic wave signals are acquired by a signal receiving device and are analyzed to obtain the signal strength of the second acoustic wave signals; and a processing device determines a relative distance between the signal receiving device and the acoustic device according to the signal strength of the first acoustic wave signals and the signal strength of the second acoustic wave signals, and determines a relative direction between the signal receiving device and the acoustic device according to the direction of the first signals. According to the invention, the problem that an audience position positioned by an acoustic system is not accurate can be solved, the acoustic system can regulate output parameters based on the change of the audience position, so that the best experience effect of the acoustic is achieved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an acoustic device-based acoustic wave positioning method and system thereof. Background technique [0002] A sound system is a core component of the digital home audio-visual experience. At present, multi-channel audio systems are gradually being promoted and popularized in ordinary families, but the quality of the audio system will directly affect the experience. Especially "multi-channel balance effect based on listener's position" and "multi-channel sound wave focusing effect based on listener's position" can really bring the ultimate sound effect to the audience. [0003] Whether it is "multi-channel balance effect based on the listener's position" or "multi-channel sound wave focusing effect based on the listener's position", the problem of the position of the listener must be solved. At present, some methods for obtaining the location of the audience in the...
