The invention discloses a HAC system based on a mobile terminal and an implementation method thereof. The HAC system based on a mobile terminal includes a mobile terminal and a coil accessory; the coil accessory includes an audio plug and a magnetic induction coil connected to the audio plug; The mobile terminal includes a mobile terminal body, a main board, an audio interface circuit and an audio jack, the main board and the audio interface circuit are arranged inside the mobile terminal body, the audio jack is arranged on the side of the mobile terminal body, the The main board, the audio interface circuit and the audio jack are connected in sequence. The invention can make the mobile terminal realize the hearing aid compatibility function without occupying the design space of the mobile terminal, and the obtained HAC system based on the mobile terminal also has the advantages of low implementation cost and simple debugging.
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...
