Unable to concentrate on driving, may even cause unfortunate traffic accidents, and even violate the relevant provisions of the law; Become a hands-free communication device.

However, it is not only inconvenient to connect the microphone and a single earphone with a wire as a communication device, because the locomotive driver first needs to put the earphone strap in the ear, and then puts on the safety helmet to communicate. It is very uncomfortable to use when plugged in the ear and pressed by the helmet. At the same time, the extended signal line is directly exposed to the outside and blows in the wind. In addition, the poor communication quality and the inconvenience of wearing a helmet are also its shortcomings.

In addition, since the motorcycle driver needs to wear a helmet when riding a motorcycle, if there is another passenger wearing a helmet in the back seat, when the motorcycle is moving, the voice of the conversation will be blocked by the helmet and the driving wind. If it is blocked, it is often impossible to clearly convey it to the other party to hear it, causing quite a lot of inconvenience, and it will also affect the safety of driving. Therefore, to above-mentioned existing locomotive with hands-free receiver device, really have the necessity of further research and development improvement.
