[0033] Combined with reference Figures 2 to 4The microphone control structure 300 includes a microphone shell 310, a PCBA board (Printed Circuit Board Assembly, which refers to a printed circuit board that has completed component installation and welding processes, also known as an electronic assembly board) 320 and a function control key 330. The microphone shell 310 is used to store and protect the internal parts of the microphone control structure 300, and the PCBA board 320 is placed in the microphone shell 310. The PCBA board, as the core control panel of the microphone control structure 300, controls the switch closure and implementation of various functions of the microphone control structure 300, and the microphone control structure 300 is electrically connected to the external circuit components through the PCBA board. The function control key 330 is arranged on the microphone shell 310 and is in electrical contact with the PCBA board. The user can control the opening and closing of the corresponding function in the microphone control structure 300 by operating the function control key 330, that is, control the power on and off of the function control key 330 and the PCBA board 320.

[0034] Combined with reference Figure 4 and Figure 5 The microphone shell 310 includes a first shell 311 and a second shell 312 that are detachably connected. The first shell 311 and the second shell 312 are enclosed to form a receiving chamber 313, and the PCBA board is placed in the receiving chamber 313. Furthermore, one of the first shell 311 and the second shell 312 is provided with a positioning groove 314, and the other is provided with a positioning protrusion 315. When the first shell 311 and the second shell 312 are aligned and covered, the positioning groove 314 and the positioning protrusion 315 are aligned and engaged so that the two shells can be stably covered and connected. The first shell 311 and the second shell 312 are separated up and down along a thickness direction perpendicular to the microphone shell 310. It should be understood that in other embodiments, first, the first shell 311 and the second shell 312 can also be connected by rotating the flip cover, and the direction of separation is not limited, as long as the microphone shell 310 forms a receiving chamber 313 for storing the PCBA board.

[0035] The PCBA board 320 includes a program burning unit, which includes one or more functional program units such as a volume program unit, a phone answering program unit, a recording unit, and a channel conversion unit, so that the microphone control structure 300 has corresponding control functions. People directly or indirectly control the closing of a small number of units of the corresponding functional program on the PCBA board by operating the function control key 330, thereby controlling the opening and closing of the corresponding function. Figure 2 and Figure 3It is illustrated that the function control keys 330 of the embodiment of the present application include an ear return switch key 331, a voice answer key 332, a channel conversion key 333, a volume increase key 334, and a volume reduction key 335. Specifically, by operating the ear return switch key 331, the on and off of the ear return function in the microphone control structure 300 can be controlled; by operating the voice answer key 332, the answering and hanging up of voice call functions such as making and receiving calls, WeChat, QQ, etc. can be controlled; by operating the channel conversion key 333, the three channels of original sound, KTV, and 7.1 channels can be cyclically converted to suit different scenes; by operating the volume increase key 334, the headphone sound is increased, and by operating the volume reduction key 335, the headphone sound is reduced. It should be understood that there is no limitation on the conversion of different channels by the channel conversion key 333 in other embodiments.

[0036] Combined with reference Figure 4 In order to fix each function control key 330 to the microphone shell 310 in a more stable and aligned manner, the microphone shell 310 is not only provided with an avoidance through-hole 316 aligned with the function control key 330, but also the avoidance through-hole 316 is provided for the function control key 330 to pass through and move back and forth under the action of external force. The inner side wall of the microphone shell 310 is provided with a positioning column 317 for positioning multiple function control keys 330. Specifically, the function control keys located on the same side of the PCBA board 320 are connected in sequence through a connecting block 336. The connecting block 336 is provided with a positioning hole 337. When the function control key 330 is received and installed in the microphone shell 310, the positioning column 317 is aligned with the positioning hole 337 to further stably clamp and position the function control key 330 on the microphone shell 310. It should be understood that, without considering the installation stability of each function control key 330, the function control keys 330 do not need to be connected together, nor do they need to be fixed through the positioning column 317 and the positioning hole 337; furthermore, the positions of the positioning column 317 and the positioning hole 337 can be interchanged, the positioning column 317 is arranged on the connecting block 336, and the positioning hole 337 can be arranged on the inner wall of the microphone shell 310.

[0037] Here, the ear return switch key 331 is taken as an example to illustrate the working process of each function control key 330. The ear return switch key 331 of this embodiment is implemented as a press key. First, the audio source plug 110 of the wired headset 10, that is, the Type-C plug, is inserted into the audio mother socket (such as a mobile phone, tablet, computer, etc.). The entire circuit of the wired headset 10 is powered on. The user puts the earplug 200 into the ear and can hear the sound emitted by the audio mother socket. At this time, when the user raps along with the sound, he can monitor his own sound through the ear return switch key 331. Specifically, when the earphone ear return function is in the off state, press the ear return switch key 331. Through the action of the PCBA board and the internal program burning unit, the earphone ear return off state mode will be converted to the on state mode. At this time, the user can hear his own rap sound through the earplug 200. When the ear return switch key 331 is pressed again, the earphone ear return on state mode will be converted to the off state mode, and the earplug 200 will not hear his own rap sound. Therefore, by simply pressing the ear return switch key 331, the ear return on and off function cycle switching effect can be realized. In particular, it is very convenient for users to monitor their own voices by turning on the ear return switch key 331 when singing karaoke and reading aloud. It should be understood that in other embodiments, the ear return switch key 331 can also be implemented as a sliding key, and the user controls the opening and closing of the ear return switch key by sliding the sliding key back and forth. In addition, in other embodiments of the present application, the voice answering key 332 and the channel conversion key 333 may not be provided, and only the ear return function is required. In addition, the control switch mode of the voice answering key 332, the channel conversion key 333, the volume increase key 334 and the volume decrease key 335 is the same as the operation mode of the ear return switch key 331.

[0038] The microphone control structure 300 with ear return function and the wired earphone 10 of the embodiment of the utility model, the wired earphone 10 includes an earplug 200, a sound source receiver 100 and a microphone control structure 300 with ear return function.

[0039] Combined with reference Figure 4 and Figure 5The microphone control structure 300 further includes an electric contact terminal 340, which is located between the function control key 330 and the PCBA board 320 and electrically contacts the PCBA board. The user operates the function control key and drives the power on and off between the electric contact terminal 340 and the PCBA board 320 to turn on and off the corresponding function. Specifically, the PCBA board 320 includes a first surface 321 and a second surface 322 opposite to each other along its thickness direction, and the electric contact terminal 340 is located between the function control key 330 and the first surface 321 or between the function control key 330 and the second surface 322. It should be understood that in other embodiments, an electric contact portion can be directly set on one end of the function control key 330 to directly achieve electrical contact with the PCBA board 320. It only needs to ensure that the function control key 330 can be in electrical contact with the PCBA board 320, and the microphone control structure 300 does not need to be provided with an independent electric contact terminal 340, but doing so will increase the processing cost. In addition, the contact position between the electric contact terminal 340 and the PCBA board 320 is not limited, and it does not necessarily have to be point-to-surface contact, and it only needs to ensure point contact between the two.

[0040] Combined with reference Figure 4 and Figure 5 In this embodiment, the microphone control structure 300 further includes a power input section 350 and a power output section 360 connected to opposite sides of the microphone control structure 300.
