Head-mounted voice transceiver

Abstract

The invention relates to a head-mounted voice transceiver, and relates to the technical field of voice transceivers, which solves the technical problems of poor call quality and uncomfortable wearing during the driving of motorcycles in the prior art. The voice transceiver is characterized by comprising a helmet, a contact microphone component, an interconnecting piece, a speaker and a deconcentrator, wherein the contact microphone component is arranged at an afterbrain position or a cheekbone position on the inner side of the helmet through the interconnecting piece, a contact surface of the contact microphone component faces an inner cavity of the helmet and can move elastically relative to the inner wall of the helmet; the speaker is arranged at an ear position of the inner side of the helmet; the deconcentrator is arranged on the helmet, and is connected with the contact microphone component and the speaker through a cable; and the deconcentrator is provided with a lead-out cable for connecting communication equipment. When the voice transceiver provided by the invention is utilized, the clear speech communication can be kept during the driving of motorcycles, and the head-mounted voice transceiver wears comfortable.

Description

technical field [0001] The invention relates to the technology of a voice transceiver, in particular to the technology of a helmet-type voice transceiver used for communication while a motorcycle is running. Background technique [0002] Motorcyclists add microphones to their helmets when they need to communicate on the move. There are currently two ways to install a microphone in a motorcycle helmet: [0003] One is to install an ordinary microphone in the helmet close to the mouth, and use the ordinary microphone to directly pick up the sound; but because the helmet mask is very close to the mouth, the microphone is sandwiched between the helmet mask and the user's mouth, and when the wearer speaks The airflow sprayed on the microphone will cause a serious popping sound, so it is difficult for the receiver to recognize the voice; and for the helmet with a non-full airtight mask, the airflow at the bottom of the motorcycle will rush into the microphone when the motorcycle ...

Problems solved by technology

[0003] One is to install an ordinary microphone in the helmet close to the mouth, and use the ordinary microphone to directly pick up the sound; but because the helmet mask is very close to the mouth, the microphone is sandwiched between the helmet mask and the user's mouth, and when the wearer speaks The airflow sprayed on the microphone will cause a serious popping sound, so it is difficult for the receiver to recognize the voice; and for the helmet with a non-full airtight mask, the airflow at the bottom of the motorcycle will rush into the microphone when the motorcycle is running at high speed, resulting in strong wind noise interference

[0004] The other is to install a contact microphone on the top of the helmet, and use the weight of the helmet to make the contact microphone close to the top of the wearer's head to collect bone conduction voice signals; however, due to the heavy weight of the helmet, the contact microphone will oppress the wearer The top of the head causes pain at the pressure point of the wearer, so it cannot be worn for a long time; and when the motorcycle is running, the airflow friction on the top of the helmet is relatively large, and the foam buffer layer on the top of the helmet can only play a buffering role, and cannot isolate friction and vibration Therefore, it will cause strong wind noise interference and affect the call quality
