Abstract

The invention discloses a hearing-aid-coil detecting device and a detecting system. The hearing-aid-coil detecting device comprises a conversion module, an amplifying module and a switch module. The amplifying module is connected with the conversion module and the switch module used for controlling the amplifying module to be started or stopped. The amplifying module is externally connected with a headset. The conversion module is used for detecting a magnetic field signal of a hearing aid coil and converting the magnetic field signal into an electric signal. The amplifying module is used for amplifying the electric signal and driving the headset to generate sounds. A detector can detect whether the performance of the hearing aid coil is normal or not by listening to the sounds through the headset; the hearing-aid-coil detecting device and the detecting system are simple in structure, convenient to operate and suitable for batch detection, and the detection result is safe and effective.

Description

technical field [0001] The invention relates to the technical field of hearing aid detection, in particular to a hearing aid coil detection device and detection system. Background technique [0002] Mobile phones shipped to the North American market are required to comply with ANSI C63.19 regulations on hearing aid compatibility. At present, mobile phone manufacturers generally adopt the design scheme of T-coil hearing aid coil to meet the regulatory requirements. [0003] Based on T-coil (electromagnetic induction coil) hearing aid coils radiate magnetic field signals, currently there are only two ways to test T-coil performance: one is to use professional testing instruments, such as DASY5 SAR testing system; its price comparison expensive. Another kind adopts the hearing aid, but the hearing aid is designed for the hearing-impaired, and it is easy to damage the hearing of normal people with it to detect the T-coil performance. [0004] Therefore, the prior art still ne...
