Description

A type of clip-on earphone Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to an ear clip-on headphone. Background Technology

[0002] Clip-on headphones are used by clipping onto the ear helix without needing to be worn inside the ear. Compared to in-ear headphones, the structure of clip-on headphones reduces the risk of developing otitis externa caused by prolonged wear, hence the increasingly widespread use of clip-on headphones.

[0003] Clip-on headphones typically have antennas to receive signals. Some headphones on the market use external antennas to improve signal quality, but the size of some antennas is limited by their own structure, resulting in a limited antenna length and generally poor signal quality.

[0004] For example, Chinese Patent Application No. CN202320645218.7 discloses an antenna peripheral headset. This headset includes a sound cavity assembly, a battery assembly, and an antenna stem. The sound cavity assembly includes a front sound cavity and a rear sound cavity, which are connected. A headphone mainboard and a speaker are disposed between the front and rear sound cavities, and the front sound cavity has a sound outlet. The battery assembly includes a front battery cavity and a rear battery cavity, which are connected. A battery is disposed between the front and rear battery cavities. The sound cavity assembly and the battery assembly are connected via the antenna stem, and the headphone mainboard and the battery are connected via a power cord. The antenna stem can radiate signals or receive radio frequency signals from mobile phones or other Bluetooth devices to achieve wireless Bluetooth signal transmission. Therefore, the antenna length in this design is limited by the length of the antenna stem, which is fixed, resulting in relatively poor signal quality. Summary of the Invention
