Abstract

The invention relates to a Bluetooth audio product antenna, which is applied to an in-ear earphone and comprises: an FPC antenna and touch control switch sharing one body, an ejector pin, a feed point, an antenna matching part, a radio frequency transmission line, a radio frequency chip, a control mainboard, a signal isolation circuit and a touch chip, wherein the FPC antenna and the touch switch sharing one body is connected with the first end of the ejector pin; the second end of the ejector pin is connected with the feed point; the first end of the feed point is connected with the first end of the signal isolation circuit; the second end of the signal isolation circuit is connected with the touch chip; the second end of the feed point is connected with the first end of the antenna matching part; and the second end of the antenna matching part is connected with the radio frequency chip. According to the embodiment of the invention, through the FPC antenna and the touch switch sharing one body, the occupied space of the antenna and the touch switch is saved, the mutual interference of the antenna and the touch switch is reduced, the radio-frequency signal transmission distance of Bluetooth is short, the radio-frequency signal transmission distance of Bluetooth is increased, and compared with the prior art, the touch area is large, and the touch function experience is good.

Description

technical field [0001] The invention relates to the technical field of bluetooth audio, in particular to an antenna for bluetooth audio products. Background technique [0002] At present, the antennas of Bluetooth audio products are generally used: 1. LDS / FPC antenna, which requires an independent antenna space. 2. For small-sized in-ear Bluetooth audio products with touch control function, the antenna placement space is occupied by the touch area, and the antenna area is squeezed, resulting in low antenna efficiency, no wireless signal radiation, poor user experience and wireless communication distance close. Regarding the small-sized in-ear Bluetooth headset, the Touch has an independent FPC / LDS, and the Bluetooth 2.4GHZ antenna is also an independent FPC / LDS, and the two are separated. [0003] The disadvantage is that the distance between the antenna and the touch is close, resulting in a short antenna transmission distance; the antenna and the touch need to occupy a l...
