Problems solved by technology

[0006] At present, there are many kinds of fully wireless earphones on the market, and their sizes are getting smaller and smaller. On the one hand, it improves the portability of the product, saves space, and meets the needs of users; however, on the other hand, it leads to some defects: Since the antenna, battery, PCB board and other components need to be accommodated in the small structural space of the in-ear type, the distance between each component is very close, and there will be strong signal interference with each other, especially in the short distance, the battery will absorb Part of the signal energy emitted by the antenna makes the connection between the master unit and the slave unit unstable, which eventually leads to poor wireless communication quality between the left and right ears, greatly affecting the audio playback effect

Embodiment 1

[0038] Please refer to Figure 4 and Figure 5 , Figure 4 and Figure 5 The structural diagram of the left earphone provided by the embodiment of the present invention. The left earphone 1 is composed of a left ear hook assembly 11 and a left earphone body 12 which are connected.

[0039] Left ear hook assembly 11, its structure is as Figure 6 As shown, it includes a metal wire core 111, a USB metal seat 112, a left earhook liner 113, and a left earhook covering layer 114; wherein, the metal wire core 111 is electrically connected to the USB metal seat 112, and the left earhook covering layer 114 is set on the outside of the metal wire core 111 and the USB metal seat 112 .

[0040] In this embodiment, the metal wire core 111 can be made of soft metal, which can be bent into different shapes at will for the convenience of users; of course, the metal wire core 111 can also be made of non-soft metal with a fixed shape, and its fixed shape is consistent with that of the use...

Embodiment 2

[0047] The solution provided by Embodiment 1 is to make the wire core inside the left earphone assembly made of conductive metal and ground it, so that the radiation field strength of the antenna inside the left earphone can be enhanced, and the stability of the communication connection between the left earphone and the right earphone can be improved. .

[0048] The solution provided in the second embodiment is: the wire core inside the right earphone is made of conductive metal and grounded to enhance the radiation field strength of the antenna inside the right earphone, and improve the stability of the communication connection between the right earphone and the left earphone. Its effect is identical with embodiment one.

[0049] In this embodiment, the right earphone is composed of a right ear hook assembly 21 and a right earphone body 22 which are connected. Please refer to Figure 10 , Figure 10 An exploded view of the right earhook assembly 21 provided for the embodim...

Embodiment 3

[0053] In Embodiment 1 and Embodiment 2, the metal cores of the left / right earhook components are connected to the PCB ground through the USB metal socket. However, in practical applications, the connection method between the metal wire core of the left / right earhook component and the PCB ground is not limited to this, and other connection sockets, such as pin sockets, audio sockets, etc., can be used, as long as the metal core can be connected The function of connecting the wire core to the ground of the PCB board is within the protection scope of the present invention.

Abstract

The invention discloses a wireless Bluetooth headset. A left headset / right headset of the wireless Bluetooth headset comprises a headset body, a battery, a PCB and an antenna module are installed in the headset body, the wireless Bluetooth headset further comprises a metal wire core arranged at the outside of the headset body, and the metal wire core is in ground connection with the PCB in the headset body. In the wireless Bluetooth headset disclosed by the invention, the wire core in an ear hook component is made of a metal material and is in ground connection with the PCB, so that the ear hook component extends the ground plane length and the area of the PCB, greatly improves the signal transmission efficiency and the signal radiation field intensity of the antenna ad effectively enhances the creeping wave transmission strength behind the brain, thereby ensuring the stability of a communication stability between the left headset and the right headset and finally improving the audio playing effect of the Bluetooth headset; and moreover, in view of the communication distance of an actually measured product, the communication distance between the left headset and the right headset is improved by more than 100%.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a wireless bluetooth earphone. Background technique [0002] Bluetooth audio receivers have been on the market for many years, and all Bluetooth audio receivers have a single system-on-a-chip integrated circuit to communicate with a Bluetooth transmitter from a smartphone, PC, or a stand-alone audio transmitter. [0003] A traditional bluetooth headset with physical wires includes: a bluetooth receiver, which is respectively connected to a left speaker and a right speaker at two ends of the bluetooth receiver through physical wires. This type of Bluetooth headset transmits signals through physical wires, and the Bluetooth receiver distributes the received audio signal to the left and right speakers. For stereo Bluetooth headsets, the stereo audio signal transmission method is as follows: the Bluetooth receiver receives stereo audio, amplifies the left and right audio signa...
