Problems solved by technology

[0002] The existing wireless earphones focus on lightness and convenience as the main research and development direction. However, the limited space inside the wireless earphones will restrict the wiring of the antenna. However, the operating bandwidth and radiation efficiency of the antenna are related to the antenna size and the antenna ground plane.
Too small antenna size and antenna ground plane will lead to deterioration of radiation performance
Nowadays, through the bending and forming of the flexible circuit board, the size of the antenna ground plane that meets the standard can be achieved. However, the inductive electronic traces in the flexible circuit board are not conducive to antenna radiation, which causes signal attenuation during transmission.
The attenuation of the radio frequency signal will cause the connection between the wireless headset and the electronic device to be unstable, which will affect the quality of the wireless headset

Abstract

The invention relates to wireless earbuds which comprise: an upper cover, a lower cover, two rigid circuit boards, a flexible circuit board and an antenna. The lower cover is connected to the upper cover, and the upper cover and the lower cover together form an internal space. The two rigid circuit boards are arranged in the internal space at intervals. The flexible circuit board has a first connection portion and a second connection portion. Two ends of the first connection part are respectively coupled to two rigid circuit boards. The second connection portion is attached to at least one ofthe two rigid circuit boards. The antenna is coupled to the corresponding hard circuit board for radiating a radio frequency signal. The parallel overlapping area of the second connection portion andthe rigid circuit board forms a coupling capacitor.

Description

technical field [0001] The present invention relates to a wireless earphone, and in particular to a wireless earphone capable of improving the operating bandwidth and radiation efficiency of an antenna. Background technique [0002] The existing wireless earphones focus on lightness and convenience as the main research and development direction. However, the limited space inside the wireless earphones will restrict the wiring of the antenna. However, the operating bandwidth and radiation efficiency of the antenna are related to the antenna size and the antenna ground plane. Too small antenna size and antenna ground plane will lead to deterioration of radiation performance. Nowadays, the size of the antenna ground plane that meets the standard can be achieved through the bending and forming of the flexible printed circuit board. However, the inductive electronic traces in the flexible printed circuit board are not conducive to antenna radiation, which causes signal attenuatio...
