Abstract

The invention discloses an HAC system based on a mobile terminal and an implementation method thereof. The HAC system based on the mobile terminal comprises the mobile terminal and a coil accessory; the coil accessory comprises an audio plug and a magnetic induction coil connected with the audio plug; the mobile terminal includes a mobile terminal body, a main board, an audio interface circuit andan audio jack, the main board and the audio interface circuit are arranged in the mobile terminal body, the audio jack is formed in the side edge of the mobile terminal body, and the main board and the audio interface circuit are sequentially connected with the audio jack. By means of the HAC system based on the mobile terminal and the implementation method thereof, the mobile terminal can achieve the compatibility function of a hearing aid on the premise of not occupying the design space of the mobile terminal, and the obtained HAC system based on the mobile terminal also has the advantagesof being low in cost and easy to debug.

Description

technical field [0001] The invention relates to the technical field of mobile terminal audio applications, in particular to a mobile terminal-based HAC system. Background technique [0002] FCC (Federal Communications Commission of the United States) has enforced the HAC (Hearing Aid Compatibility) certification program for mobile phone manufacturers for people with hearing impairments. Its HAC reference standard is ANSI C63.19 (US National Standard Method for Compatibility Measurement of Wireless Communication Equipment and Hearing Aids). According to the standard definition, consumers can judge the compatibility of a certain type of hearing aid with mobile phones by the anti-interference level of hearing aids and the corresponding mobile phone signal emission level. [0003] When the mobile phone is designed to be compatible with hearing aids, it is necessary to add an inductance coil as an antenna, and some manufacturers add the coil to the inside of the receiver to make...
