[0026] Reference Figure 1A singing audio-visual box includes: a box body 100, an audio interface 515, a video interface 535, a conversion module 700, and a control component 300. Both the audio interface 515 and the video interface 535 are located within the box body 100. The audio interface 515 is used to connect to an audio cable or a wireless receiver and input an audio signal; the video interface 535 is used to connect to a video cable and output a video signal. The conversion module 700 is installed inside the box body 100, and both the audio interface 515 and the video interface 535 are electrically connected to the conversion module 700. The conversion module 700 can convert the audio signal input through the audio interface 515 into a video signal output through the video interface 535. The control component 300 is located within the box body 100 and is used to adjust the video signal output by the conversion module 700. After a microphone is connected to the conversion module 700 through the audio interface 515, it can transmit an audio signal to the conversion module 700 inside the box body 100, thereby enabling the conversion module 700 to convert the audio signal into a video signal. Subsequently, the conversion module 700 can output the video signal to the video cable via the video interface 535, allowing video playback devices such as monitors to receive the audio signal transmitted from the audio source. This enables the monitor to smoothly play the audio signal input from the microphone without requiring the playback device to have an audio input interface. The control component 300 allows users to adjust the sound played by the playback device through the housing 100, thus allowing users to adjust the playback effect without moving to the playback device, effectively improving the convenience of adjusting the playback effect during singing entertainment.

[0027] In some embodiments, reference is made to Figure 1 The control component 300 includes a button 320 disposed on the surface of the housing 100. The button 320 is electrically connected to the conversion module 700 and is used to control its opening and closing. When the button 320 is pressed, the opening and closing of the conversion module 700 can be directly and conveniently controlled, thereby smoothly starting or stopping the signal input or output effect between the audio interface 515 and the video interface 535. This also allows for the plugging and unplugging of the audio or video connection cable, and enables the singing entertainment to start or stop.

[0028] In some embodiments, reference is made to Figure 1 The control component 300 includes a knob 310 disposed on the surface of the housing 100, and the conversion module 700 includes a tuning component. The knob 310 is electrically connected to the tuning component and is used to control the state of the audio signal output by the video interface 535. When the knob 310 is rotated, its rotation amount can control the volume of the tuning component, thereby facilitating the adjustment of the content played by the playback device.

[0029] Specifically, the tuning component can be a power amplifier circuit, with knob 310 electrically connected to the power amplifier circuit and able to adjust the output gain of the power amplifier circuit. Of course, the tuning component can also be composed of other components, such as a differential amplifier circuit, which amplifies the electrical signal. The specific implementation method is not unique and can be adjusted according to the actual situation; no restrictions are imposed here.

[0030] In some embodiments, reference is made to Figure 1 Multiple knobs 310 are present, each electrically connected to the tuning component. One of the knobs 310 controls the volume of the sound signal, while another knob 310 controls the bass intensity. These multiple knobs 310 allow for individual adjustment of sound parameters such as volume and bass intensity, enabling users to conveniently and comprehensively control the music being played, thus satisfying diverse musical needs.

[0031] Specifically, there are two knobs 310. Of course, the number of knobs 310 can also be other, such as three, four, or five. Knobs 310 can also be used to switch ambient sound effects and other functions. The specific implementation method is not unique and can be adjusted according to the actual situation, and no restrictions are imposed here.

[0032] In some embodiments, reference is made to Figure 1 The surface of the box 100 is provided with multiple label positions 370, and the label positions 370 and the knobs 310 are distributed one-to-one. Labels can be pasted at the label positions 370, so that the function of the knobs 310 can be indicated or unlocked through the labels, thereby making it easier for users to quickly connect the functions corresponding to each knob 310, thus providing convenience in the use of the knobs 310.

[0033] In some embodiments, reference is made to Figure 2 The audio interface 515 includes an AUX interface 510, which is disposed on the surface of the housing 100 and electrically connected to the conversion module 700. The AUX interface 510 is a universal audio input interface that can input audio from electronic audio devices, including MP3 players. It has the advantages of wide applicability and support for multiple formats, thus enabling the audio signal obtained by the microphone to be successfully input into the conversion module.

[0034] In some embodiments, reference is made to Figure 2The audio interface 515 includes a microphone interface 520, which is disposed on the surface of the housing 100 and electrically connected to the conversion module 700. The microphone interface 520 works by digitizing the audio signal captured by the microphone or other audio input device and then transmitting it through a line to an electronic device for further processing or playback. Therefore, the microphone interface 520 can smoothly input audio signals into the conversion module 700, facilitating subsequent conversion of the audio signal by the conversion module 700.

[0035] In some embodiments, reference is made to Figure 2 The video interface 535 includes an HDMI interface 530, which is disposed on the surface of the housing 100 and electrically connected to the conversion module 700. HDMI can transmit audio and video signals simultaneously, so the audio signal input to the audio interface 515 can be smoothly output to the playback device from the HDMI interface 530, thereby facilitating the playback device to play and amplify audio.

[0036] In some embodiments, reference is made to Figure 2 The video interface 535 includes a MicroUSB interface 540, which is disposed on the surface of the housing 100 and electrically connected to the conversion module 700. The MicroUSB interface 540 has the advantages of easy plugging and unplugging and fast transmission speed, so it can easily transmit the data in the conversion module 700 to the playback device via a data cable, thereby enabling the playback device to play the audio signal input to the audio interface 515.

[0037] In some embodiments, reference is made to Figure 3 The conversion module 700 includes an acquisition module, an encoding module, and an encapsulation module electrically connected in sequence. The acquisition module is electrically connected to the audio interface 515, and the encapsulation module is electrically connected to the video interface 535. The acquisition module can acquire and decode audio signals, thereby enabling the audio signals to be decoded into general electrical signals. Then, the encoding module re-encodes the audio signals, and the encapsulation module encapsulates the re-encoded signals into video signals, thus converting the audio signals into video signals, which are then convenient for playback devices to play.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
