Description

Technical Field

[0001] The utility model relates to the technical field of head-mounted wireless earphones, in particular to a head-mounted earphone. Background Art

[0002] Wireless headphones are devices that use speakers close to the ears to convert electrical signals into audible sound waves without visible connecting wires. The wires in the middle are replaced by radio waves. Compared with wired headphones, wireless headphones have little difference in sound quality, and wireless is more convenient. Wireless headphones are divided into three categories: Bluetooth headphones, infrared headphones, and 2.4G headphones. The connection between the connecting belt and the headphone body in wireless headphones is usually a movable connection, which is easy to use. However, the rotation limit mechanism of the head-mounted wireless headphones in the prior art usually cannot effectively limit the rotation of the headphones, thereby reducing the comfort of wearing the headphones. In this regard, we propose a rotation limit mechanism for head-mounted wireless headphones. Utility Model Content
