Antenna and Bluetooth wireless earphone

Abstract

The embodiment of the invention provides an antenna and a Bluetooth wireless earphone, and relates to the technical field of communication equipment. The antenna is arranged in the Bluetooth wirelessearphone, and a shell of the Bluetooth wireless earphone comprises an ear handle part, an ear plug part and a corner part, wherein a first circuit board is arranged in the ear plug part, a second circuit board is arranged in the ear handle part, the antenna comprises a first antenna arm, and the first antenna arm is laid on the first circuit board; the antenna also comprises a second antenna arm,the second antenna arm is laid on the second circuit board, and the first antenna arm and the second antenna arm are connected with the transceiver through a feed structure. According to the antenna and the Bluetooth wireless earphone provided by the embodiment of the invention, a bracket for arranging the first antenna arm and the second antenna arm does not need to be independently arranged, sothat the structure is simplified; meanwhile, the space occupied by the bracket is saved, and when the antenna is applied to the Bluetooth wireless earphone, the size of the Bluetooth wireless earphonecan be effectively reduced, so that the Bluetooth wireless earphone meets the miniaturization design requirement of electronic equipment.

Description

technical field [0001] The present application relates to the technical field of communication equipment, in particular to an antenna and a Bluetooth wireless earphone. Background technique [0002] At present, the antennas in True Wireless Stereo (TWS) earphones mostly use ceramic antennas, laser direct structuring (LDS antennas) or steel sheet antennas (Flexible Printed Circuit Board, FPC antennas). Since the LDS antenna uses a laser to laser the antenna on the bracket, its application range far exceeds that of ceramic antennas and FPS antennas. Generally, LDS antennas use monopole antennas. [0003] figure 1 The structure shown is a commonly used structure of TWS earphones in the prior art. Since the TWS earphones are small in size but have many components, and the internal space of the product is tight, the antenna bracket 001 with the LDS antenna of the TWS earphone is set on the top of the ear handle of the earphone. The antenna support 001 is connected to the radio ...

[0003] figure 1 The structure shown is a commonly used structure of TWS earphones in the prior art. Since the TWS earphones are small in size but have many components, and the internal space of the product is tight, the antenna bracket 001 with the LDS antenna of the TWS earphone is set on the top of the ear handle of the earphone. The antenna support 001 is connected to the radio frequency terminal on the circuit board 003 through the feed structure 002, which will cause the earphone to form a protrusion at the top of the ear handle to accommodate the antenna support 003, so that the volume of the entire TWS earphone increase, which deviates from the miniaturization design requirements of electronic products

At the same time, according to the antenna pattern of the head model, there is a gain zero point in the radiation direction of the antenna outside the head model, that is, there is uneven signal coverage, which affects the communication experience
