Problems solved by technology

Once the TRP value is too large, it will lead to a strong electromagnetic field near the earpiece of the wireless communication device, making the M level lower, which is not conducive to the reception of hearing aids and affects the compatibility of the two

Abstract

The invention provides a wireless communicator, which comprises a circuit board, a headphone, an antenna module and a hearing aid compatible module. The headphone and the antenna module are arranged on the circuit board, the hearing aid compatible module is arranged close to the antenna module and comprises a grounding part, the grounding part comprises a first grounding portion, a second grounding portion and a connecting portion, the shape and the structure of the first grounding portion are identical to those of the second grounding portion, the first grounding portion and the second grounding portion are symmetrically arranged, the connecting portion is perpendicularly connected with the first grounding portion and the second grounding portion, when the wireless communicator works, the grounding part realizes functions of an antenna and is used for improving the current direction of the antenna module, and accordingly an electric field and a magnetic field nearby the headphone are improved.

Description

technical field [0001] The present invention relates to a wireless communication device, in particular to a wireless communication device compatible with hearing aids. Background technique [0002] A hearing aid is a tool, device, device or instrument that picks up sound waves in the air through the earpiece, converts the sound waves into electrical signals, and then amplifies the signals as needed, and then converts them into sounds that the user can hear. However, when a hearing aid is used simultaneously with a wireless communication device such as a mobile phone, the antenna of the wireless communication device will generate an electromagnetic field around the earpiece of the wireless communication device. The pulsations generated by these electromagnetic fields will be picked up by the earpiece of the hearing aid or the telecoil circuit, which may generate noise in the hearing aid, making the wireless communication device and the hearing aid incompatible. Therefore, wh...
