WIRELESS EARPHONE

WIPO Patent Application WO/2024/037047

A1

The present application provides a wireless earphone, comprises an earphone antenna, an earplug portion, and a lever portion. The earphone antenna comprises a main antenna unit and a resonance unit. The main antenna unit comprises a first radiation stub disposed on the lever portion. The resonance unit is disposed on the lever portion and comprises a first metal stub. The first radiation stub and the first metal stub are arranged opposite to each other and are both disposed in the extension direction of the lever portion. The first radiation stub is located on the side away from the earplug portion, and the first metal stub is located on the side close to the earplug portion. The resonance unit is used for performing electric field coupling with the main antenna unit. According to the wireless earphone, by adding the resonance unit to the main antenna unit, and forming electric field coupling between the main antenna unit and the resonance unit, a parallel electric field component generated by the first radiation stub can be converted into a vertical electric field component, such that the parallel electric field component which can be absorbed by a human body is reduced and the vertical electric field component which is difficult to be absorbed by the human body is increased, and thus, the radiation performance of the earphone antenna can be improved.
