Antenna and bluetooth wireless earphone

Abstract

The embodiment of the present application provides an antenna and a Bluetooth wireless earphone, which relate to the technical field of communication equipment. The antenna is arranged in the Bluetooth wireless earphone. The shell of the Bluetooth wireless earphone includes an ear handle, an earplug, and a corner. The earplug is provided with a first circuit plate, the ear handle is provided with a second circuit board, the antenna includes a first antenna arm, the first antenna arm is laid on the first circuit board; the second antenna arm, the second antenna arm is laid on the second circuit board, the first Both the antenna arm and the second antenna arm are connected to the transceiver through a feed structure, and the antenna and the Bluetooth wireless earphone provided in the embodiment of the present application do not need to separately set up a bracket for laying out the first antenna arm and the second antenna arm, which simplifies the At the same time, the space occupied by the bracket is saved, and the application of the antenna in the Bluetooth wireless headset will effectively reduce the volume of the Bluetooth wireless headset, so that the Bluetooth wireless headset can meet the miniaturization design requirements 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
