Compared with the four-stage headset in the prior art, the microphone core used is usually a 6mm diameter omnidirectional microphone core with a small diaphragm, poor sound details, and high ambient noise, resulting in poor performance. The sound pickup module 1101 shown in this embodiment uses a 9.7mm diameter electret cardioid directional condenser microphone, which effectively reduces the impact of ambient noise, has a large diaphragm, higher sound pickup sensitivity, clearer sound, rich sound details, and better sound quality.

[0069] Specifically, the first connection module includes a first wired interface 1105 and a first antenna 1106, wherein the first wired interface 1105 can be a TYPE-C interface, and the first wired interface 1105 can be connected to the terminal device 6 via a data cable.

The external device can be a computer, tablet, mobile phone, XBOX game controller, camera, etc., and this embodiment does not limit this. The receiver can realize data transfer of the collected user voice to meet the needs of complex scenarios, such as gaming e-sports scenarios.

The frequency band where the radio frequency signal is located is universal worldwide and is not affected by regional regulations, thereby improving the adaptability of the entire wireless microphone.

[0072] This embodiment greatly improves the stability of the cooperation between the transmitter body 11 and the earphones through the design of the first magnetic base 12 and the second magnetic base 13, and the transmitter body 11 is powered by a first power module and can work normally without connecting to the earphones for power; the transmitter body 11 and the receiver component transmit data wirelessly through a 2.4G private protocol, and the earphones do not need to provide additional connecting cables and interfaces; without affecting the normal functions and usage experience of the earphones, the functions of the microphone and the earphones are superimposed, and the wireless microphone can be quickly installed on any head-mounted headphones 4 and wirelessly connected to the terminal device 6, making it more convenient and flexible to use; the transmitter component 1 can realize the sound pickup function, and the receiver component can transmit audio to external devices, making the use of audio more diversified, and solving the problem of no sound pickup function when using earphones alone. Whether it is a monitoring earphone or a gaming earphone, by matching it with the wireless microphone, users can realize functions such as recording and voice communication, bringing a better usage experience to users.

When the first battery 1107 is connected to the first wired interface 1105, the first wired interface 1105 can be connected to a 5V power adapter to charge the first battery 1107. Therefore, when the first wired interface 1105 is connected to the terminal device 6, the first battery 1107 can be simultaneously charged, thus achieving multifunctional utilization of the first wired interface 1105. Specifically, the transmitter body 11 uses a TYPE-C charging input interface and a polymer lithium-ion battery with a built-in battery protection board as the first battery 1107 to power the various functional modules of the transmitter body 11.

Specifically, the first touch button 1103 is a touch chip ASC0101B. The first touch button 1103 recognizes a single-click operation and then transmits a detection signal to the control chip JL7016M of the first control unit 1102. After the first control unit 1102 recognizes the signal, the signal output enable pin of the corresponding transmitter body 11 switches the high and low level signals, thereby controlling the switching of the sound signal mute and sound pickup states. At the same time, the first control unit 1102 also controls the corresponding mute status indicator. When the transmitter body 11 is muted, the mute status indicator lights up, and when the transmitter body 11 picks up sound, the mute status indicator goes out. Similarly, by long pressing the first touch button 1103, the software algorithm noise reduction mode of the first control unit 1102 during the sound pickup process can be turned on or off. After the noise reduction mode is turned on, the first noise reduction control circuit 1110 is turned on, and the ambient noise is filtered out. Only the human voice is picked up, thereby obtaining high-quality audio. The noise reduction status indicator lights up and goes out accordingly as the noise reduction mode is turned on and off.

[0076] The second button submodule 1104 includes a first button 1111 and a second button 1104. The first button 1111 is the power button for the transmitter body 11, and the second button 1104 is the volume adjustment button for the transmitter body 11.
