Description

technical field [0001] The invention relates to an electroacoustic device, in particular to a wireless earphone. Background technique [0002] Sports earphones are newly-emerged Bluetooth wireless earphones, which are usually used in conjunction with mobile phones to receive radio signals from mobile phones in Bluetooth and convert them into sound. The sports earphone has a U-shaped bracket made of hard plastic integrally formed. The front ends of the bracket both sides (side brackets) are respectively bent downwards, and earplug shells are respectively arranged at the ends of the front ends of the two side brackets. An earplug movement is installed in each earplug shell. A bluetooth circuit, a digital / audio conversion and control circuit and a battery are installed inside the middle part of the bracket. Multiple control buttons are arranged on the bracket. The data input / output port of the digital / audio conversion and control circuit is connected to the Bluetooth circuit...

AI Technical Summary

Problems solved by technology

[0003] However, the existing sports earphones have the following disadvantages in use: 1, the integrally formed support, the fixed size cannot adapt to the changes in the size of the head shape of different users, and sometimes the root of the side support is broken.

2. If the root of the side bracket is designed as a foldable structure, the bracket will lose its elastic clamping force. In various sports occasions, the sports earphones are easy to loosen and fall off

3. The split bracket is not easy to seal. Once rain or sweat soaks into the bracket, the electronic circuit inside will not work normally, and the battery will be damaged in severe cases.
