As people's living standards continue to improve, modern communication tools, such as mobile phones, are increasingly being used by more people. However, in actual use, when there is an incoming call, but both hands are busy with other matters (such as driving) and can not hold the phone by hand, you can only put the mobile phone on the shoulder, and hold the phone with your ears sideways. Calling, if the time is long, often makes the neck feel tired. As a result, the hands-free calling method of mobile phones has been developed. At present, there are two types of hands-free calling methods for mobile phones. One is to switch the mobile phone to the amplified mode during the call, and the other is to use the external headset/microphone device on the mobile phone. There are deficiencies in the way you talk. For a mobile phone with a sound amplification function, when talking in a public place, on the one hand, it may interfere with others due to a large volume, and on the other hand, when the content of the call involves personal privacy, the user feels inconvenience: In the case of a mobile phone for a headphone/microphone device, since the earphone/microphone device has a long cable, it is inconvenient to carry.

However, if a mobile phone hands-free device is designed to allow the user to hang the mobile phone on the ear to talk, the problem caused by the hands-free calling mode of the two mobile phones can be solved. And currently, consumer electronics such as mobile phones are moving toward light and short To develop, this will not increase the burden on the ears.
