Embodiment Construction

[0053] The specific implementation manner of the sound source locating method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0054] In one embodiment, a method for locating a sound source is provided, referring to figure 1 said, figure 1 It is a flow chart of the sound source location method in one embodiment of the present invention, comprising the following steps:

[0055] Step S102, controlling the audio source to be located to play a test audio signal, and recording the start playing time of the test audio signal.

[0056]Wherein, the sound source to be located may include an audio playback device such as a sound box with a speaker.

[0057] Specifically, the preset test audio signal can be played through the sound source to be located, and the start playing time of the test audio signal played by the sound source can be recorded.

[0058] In one embodiment, the audio source to be located may be controlled to ...

Abstract

The invention provides a sound source locating method and a sound source locating system, and the method comprises the following steps: controlling a to-be-located sound source play test audio signal,and recording start play time of the test audio signal; acquiring an audio signal at a preset reference point, identifying the test audio signal from the audio signal according to feature informationof the test audio signal, and determining arrival time of the test audio signal; according to difference between start play time and arrival time of the test audio signal, calculating relative distance between the sound source and the reference point, and determining a position of the sound source according to the relative distance and the position information of the reference point. The method and the system provided by the invention overcome a problem of inaccuracy of sound source locating caused by judging the position of the sound source through a propagation attenuation coefficient in the conventional technologies, achieve the technical effect of accurately locating the sound source and provide quality guarantee for performing sound field restoration through the sound source.

Description

technical field [0001] The invention relates to the field of audio technology, in particular to a method and system for locating a sound source, a method for locating a speaker system, and a speaker system. Background technique [0002] With the development of audio technology, audio equipment has higher and higher requirements for audio playback quality, and higher requirements are put forward for the positioning accuracy of sound sources of audio equipment. Taking the speaker system as an example, the restoration of the audio sound field needs to be based on the accurate positioning of the sound source of the speaker. If the positioning of the sound source is not accurate, the sound field information played through the speaker system cannot be accurately restored. [0003] The traditional technology judges the position of the sound source by collecting the amplitude of the audio signal played by the sound source and judging the position of the sound source according to the...
