Document Type and Number:
WIPO Patent Application WO/2019/205396
Kind Code:
A1
Abstract:
The utility model relates to the technical field of earphones, and discloses an earphone using an L-shaped probe and a feed patch antenna for transceiving a signal. The earphone comprises a wireless circuit board, a panel, a probe, a patch, and a PCB. A bottom portion of the PCB is provided with the wireless circuit board. The PCB is electrically connected to the probe. A top portion of the PCB is provided with the panel. The other terminal of the probe is electromagnetically coupled to the patch. The utility model can be made into different geometric shapes according to different designs and is capable of supporting multiple frequency bands on the basis of different design characteristics. The invention provides high directionality to enhance the transceiving performance of an earphone product. In addition, the antenna is incorporated as part of the exterior appearance of the earphone product, further enhancing the transceiving performance thereof, and allowing more space for PCB circuit design.
