Abstract

The invention discloses a sound signal acquisition method and apparatus. The method is applied to a mobile terminal. The mobile terminal comprises a first sound acquirer and a second sound acquirer. The method comprises the following steps of A, acquiring a first sound signal and a second sound signal, acquired by the first sound acquirer and the second sound acquirer, of an external environment of the mobile terminal; B, comparing a first audio parameter of the first sound signal with a second audio parameter of the second sound signal, and generating a first comparison result, wherein the first audio parameter includes a first signal amplitude of the first sound signal, and the second audio parameter includes a second signal amplitude of the second sound signal; and C, selecting the sound signal acquired by at least one of the first sound acquirer and the second sound acquirer according to a first comparison result. According to the sound signal acquisition method and apparatus, the situation that the mobile terminal cannot accurately and clearly obtain a sound of the external environment of the mobile terminal due to a shielded sound inlet of the mobile terminal can be avoided.

Description

technical field [0001] The invention belongs to the technical field of sound signal acquisition, and in particular relates to a sound signal acquisition method and device. Background technique [0002] The microphone circuit of a traditional mobile terminal (for example, a mobile phone) is generally arranged at the bottom of the mobile terminal, and the shape of the sound inlet of the microphone circuit is generally circular or oval. [0003] When the user holds the mobile terminal with one hand to make a call, the sound inlet hole is often blocked by the user's hand, so that the mobile terminal cannot accurately and clearly obtain the user's voice, which will cause the other party in the call to Can't hear the call clearly. [0004] Since the gestures of different users holding the mobile terminal are different, no matter where the microphone circuit is located at the bottom of the mobile terminal, the sound inlet hole of the microphone circuit may be used by the user. ha...
