[0058] refer to Figures 6 to 11 An audio transmitter, comprising:

[0059] The main body 1 has a receiving cavity 12 formed around its sidewalls 11;

[0060] The control board 2 is located inside the receiving cavity 12;

[0061] The wireless transmitter 3 is electrically connected to the control motherboard 2. The wireless transmitter 3 is used to send the audio signal of the audio device 10 to the wireless receiver 200 of the external speaker device 20.

[0062] The first XLR connector 4 is connected to the main body 1 and electrically connected to the control motherboard 2. The first XLR connector 4 is used to connect to the audio device 10 to transmit the audio signal of the audio device 10 to the wireless transmitter 3.

[0063] With the above structure, the first XLR connector 4 is inserted into an audio output device, such as an electric guitar, bass, keyboard, or other musical instrument. The audio signal from the audio device 10 is input to the control motherboard 2 through the first XLR connector 4 and wirelessly transmitted by the wireless transmitter 3.

An operation panel 14 is provided on the side wall 11 of the main body 1, and the operation button group 7 is located on the operation panel 14. Through this structure, the operation button group 7 of the main body 1 is located on the operation panel 14 on the side wall 11 and electrically connected to the control motherboard 2, allowing users to conveniently and intuitively control various functions of the audio transmitter through the operation panel 14, such as power on / off, volume adjustment, or mode switching. This layout improves the convenience and visibility of operation, increases the efficiency of the device, and thus enhances the usability and practicality of the audio transmitter.

[0066] In this embodiment, the operation button group 7 includes a frequency modulation pressing device 72, the main body 1 is provided with a first indicator light 21, the frequency modulation pressing device 72 and the first indicator light 21 are electrically connected to the control motherboard 2, and the frequency modulation pressing device 72 is used to switch the communication channel of the wireless transmitter 3.

[0067] Specifically, the first indicator light 21 includes seven colored lights, and the communication channels have seven sets of communication channels, each matching one of the seven colored lights. The audio receiver has a second indicator light 201. When the FM press device 72 switches to the same color light emitted by the first indicator light 21 as the second indicator light 201, the wireless transmitter 3 and the wireless receiver 200 are successfully paired. The seven sets of communication channels include one automatically connected communication channel and six manually adjustable communication channels. When the audio transmitter and audio receiver are turned on, the automatically connected communication channel will automatically identify and pair with the receiver. Through the above structure, by cooperating the FM press device 72, the first indicator light 21, the control motherboard 2, and the second indicator light 201, intuitive, fast, and reliable wireless channel matching and transmission status prompts can be achieved. Simply turn on the audio transmitter and the audio receiver simultaneously, and they can automatically identify and cooperate on the automatic connection communication channel. When it is necessary to switch to other communication channels, the user only needs to switch to the communication channel with the same color as the first indicator light 21 and the second indicator light 201 through the FM press device 72, which can realize the automatic pairing of the wireless transmitter 3 of the audio transmitter and the wireless receiver 200 of the audio receiver, greatly improving the convenience of device pairing, operation efficiency, and reliability of use.

[0068] In this embodiment, the frequency modulation pressing device 72 includes a frequency modulation elastic switch 721 and a light-transmitting button 722. The frequency modulation elastic switch 721 is mounted on the control main board 2, and the light-transmitting button 722 is mounted on the side wall 11 of the main body 1. The light-transmitting button 722 includes a light-transmitting part 7221 located in the middle and a pressing end 7222 located on the side. The light-transmitting part 7221 is exposed outside the main body 1, and the pressing end 7222 contacts the frequency modulation elastic switch 721 to trigger the frequency modulation elastic switch 721 when the light-transmitting button 722 is pressed. The first indicator light 21 is mounted on the control main board 2, and the first indicator light 21 is arranged opposite to the light-transmitting part 7221 so that the light emitted by the first indicator light 21 can be transmitted through the light-transmitting part 7221. The operation panel 14 is provided with a third through hole 143, through which the light-transmitting part 7221 can pass and expose the main body 1.

[0069] With the above structure, since the pressing end 7222 of the light-transmitting button 722 is in contact with the frequency modulation elastic switch 721, the user can trigger the switch operation by pressing the light-transmitting button 722. At the same time, the light-transmitting part 7221 can transmit the light emitted by the first indicator light 21 on the control motherboard 2 evenly to the outside without obstruction, so that the user can intuitively observe the color change of the first indicator light 21 to know the current frequency modulation status.

The first indicator light 21 is located between the elastic support member 723 and the frequency modulation elastic switch 721.

[0071] With the above structure, since the control motherboard 2 is equipped with an elastic support 723, the pressing end 7222 at the lower end of the light-transmitting button 722 contacts the frequency modulation elastic switch 721, and the supporting end 7223 at the upper end of the light-transmitting button 722 abuts against the elastic support 723. When the user presses the light-transmitting button 722, the supporting end 7223 squeezes the elastic support 723, and the pressing end 7222 triggers the frequency modulation elastic switch 721. After the button is released, the frequency modulation elastic switch 721 and the elastic support 723 automatically rebound, realizing the reset of the light-transmitting button 722. At the same time, the first indicator light 21 is set between the elastic support 723 and the frequency modulation elastic switch 721, and the light can pass through the light-transmitting part 7221 without obstruction to display the current channel status. Compared with the traditional design that requires two elastic switches to reset the light-transmitting button 722, the design in this embodiment is simpler and more ingenious, effectively realizing the automatic reset function of button operation, and also ensuring the clear visibility of the indicator light signal, thus improving the user experience.

[0072] In this embodiment, the light-transmitting button 722 is connected to a mounting part 724. The mounting part 724 has a first mounting hole 7241 and a second mounting hole 7242. The inner wall of the main body 1 has a first mounting post 101 and a second mounting post 102. The first mounting hole 7241 and the second mounting hole 7242 of the mounting part 724 are respectively sleeved and connected to the first mounting post 101 and the second mounting post 102, so that the light-transmitting button 722 is installed on the inner wall of the main body 1. With the above structure, the light-transmitting button 722 is sleeved on the first mounting post 101 and the second mounting post 102 on the inner wall of the main body 1 through the first mounting hole 7241 and the second mounting hole 7242 on its mounting part 724. This design makes the light-transmitting button 722 securely fixed and accurately positioned, ensuring the stability and sensitivity of the button operation, and avoiding the impact of loosening or displacement on button triggering and the display of the first indicator light 21.

[0073] In this embodiment, the system also includes a battery 8 disposed within the receiving cavity 12 and a power indicator light 81 disposed on the main body 1. The battery 8 and the power indicator light 81 are electrically connected to the control motherboard 2, and the power indicator light 81 is used to display the power level of the battery 8.
