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 present invention provides a sound source location method and system. The method comprises the steps of: controlling sound source play test audio signals to be located, and recoding starting playtime of the test audio signals; collecting audio signals at preset at least two reference points, respectively identifying the test audio signals in the collected audio signals collected at each reference point according to feature information of the test audio signals, and determining arrival time of the test audio signals arriving at each reference point; calculating the relative distance between a sound source and each reference point according to time difference between the starting play time of the test audio signals and the arrival time of the test audio signals arriving at each reference point, and determining the position of the sound source according to the relative distance of the sound source and each reference point. The method and the system overcome the problem that a traditional technology employs a propagation attenuation coefficient to determine the position of the sound source to cause inaccurate sound source location, achieve the technical effect of accurately locating the sound source and provide quality guarantee for audio sound field restoring by employing 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...
