Abstract

The invention discloses a mobile terminal, an audio signal processing method and an audio signal processing device. The method comprises the following steps of: monitoring whether a hearing-aid is used within a monitoring range of the mobile terminal; while monitoring that the hearing-aid is used, calling a first frequency response parameter and a first volume gain parameter which are set in advance; adjusting an audio signal of the mobile terminal according to the called first frequency response parameter and the first volume gain parameter; if no use of the hearing-aid is monitored, calling a second frequency response parameter and a second volume gain parameter which are set in advance; and adjusting the audio signal of the mobile terminal according to the called second frequency response parameter and the second volume gain parameter. Only an audio output part is changed; the radio performance of the mobile terminal is ensured to be not changed; and moreover no coils are increased, so that the cost is reduced.

Description

【Technical field】 [0001] The present invention relates to the field of mobile terminals, in particular to a mobile terminal and an audio signal processing method and device thereof. 【Background technique】 [0002] With the continuous popularization of mobile terminals, users have higher and higher requirements on the functions of mobile terminals, such as mobile phones. [0003] Hearing aids in the prior art are divided into two modes: acoustic coupling (M-Ratings) and inductive coupling (T-Ratings). When the hearing aid in the acoustic coupling mode is working, the surrounding sound is collected by a built-in microphone in the hearing aid, and the collected sound is processed. Post-amplification; when the hearing aid in inductive coupling mode is working, the built-in microphone is turned off to avoid amplifying environmental noise, and the audio signal in the audio frequency band is induced through coil coupling. [0004] Since the mobile terminal is in the communication ...
