Document Type and Number:
WIPO Patent Application WO/2024/037051
Kind Code:
A1
Abstract:
The present application provides a wireless earphone, comprising an earphone antenna, an earbud portion, and a stem portion. The earphone antenna comprises a main antenna unit and a resonance unit, and the main antenna unit comprises a first radiation branch provided on the stem portion. The resonance unit is arranged on the stem portion and comprises a first metallic branch. The first radiation branch and the first metallic branch are oppositely arranged and both are arranged along the extending direction of the stem portion. The first radiation branch is located on the side away from the earbud portion, and the first metallic branch is located on the side close to the earbud portion. The resonance unit is used for performing electric field coupling with the main antenna unit. According to the wireless earphone, the resonance unit is added to the main antenna unit, so that the electric field coupling is generated between the main antenna unit and the resonance unit, and the parallel electric field component generated by the first radiation branch can be converted into a vertical electric field component, thereby reducing the parallel electric field component that can be absorbed by a human body and increasing the vertical electric field component that is difficultly absorbed by the human body, and then improving the radiation performance of the earphone antenna.
