Abstract

The invention discloses a state control method, a state control module and a state control system of an HAC power amplifier. The method comprises the following steps: transmitting an ON OR OFF value of controlling the HAC power amplifier by menu operation to a bottom layer code through a KCTRL command; recording the state of the ON OR OFF through a newly added state value by a bottom layer; and controlling the on or off of the HAC power amplifier according to an opening and closing state of an audio receiver and the newly added state value. An HAC function is configured in a mobile phone and can realize the compatibility of the mobile phone and a hearing-aid so as to facilitate the use of a user with hearing disorder and wearing the hearing-aid; and as the HAC function is configured, the power amplifier can further enhance the sound effect, and the mobile phone targets at the user with hearing disorder, so the function of sound enhancement is more obvious.

Description

technical field [0001] The invention relates to the field of mobile terminals, in particular to a state control method, a state control module and a control system of an HAC power amplifier. Background technique [0002] The radio waves sent by the mobile phone will form an electromagnetic field around the antenna, causing the user wearing the hearing aid to hear a harsh buzzing sound, and the mobile phone is not compatible with the hearing aid. Generally, low-end mobile phone models use M3 coils for compatibility, and some mobile phones have HAC function. HAC is the abbreviation of Hearing Aid Compatibility. It is a standard for mobile phones to support hearing aid compatibility. Mobile phones with HAC function are used by users who have hearing impairment and need to wear hearing aids. However, in the prior art, the mobile phone with the HAC function is not equipped with a power amplifier function, and the audio playback sound is low. [0003] Therefore, the prior art st...
