When the protrusion 5 rotates to the inside of the inner wall groove 3, the spring 7 rebounds, so that the movable block 8 blocks the notch 6, thereby completing the blocking.

[0025] Furthermore, the connection unit 2 includes a USB interface 9, a voltage conversion unit 10, a receiver 11 and a signal conversion unit 12.

[0026] Furthermore, the connection unit 2 is connected to the power amplifier component 4 through the output end of the signal conversion unit 12 using a flexible cable; the use of the flexible cable increases the flexibility and reliability of the connection and reduces the risk of connection interruption due to vibration or external force.

[0027] Working principle: First, the device receives external power or data signals through the USB interface 9. The output end of the USB interface 9 is connected to the input end of the voltage conversion unit 10. The voltage conversion unit 10 is responsible for converting the input electrical energy into a voltage suitable for the operation of each component inside the device to ensure the stable operation of the entire system. The converted electrical energy is supplied to the receiver 11. The receiver 11 is used to receive audio and video signals from the outside. After receiving the signal, the receiver 11 passes it to the signal conversion unit 12 for further processing. The signal conversion unit 12 decodes, amplifies and processes the received audio and video signals to make them suitable for amplification by the power amplifier component 4. The processed signal is transmitted to the power amplifier component 4 through a flexible cable. The use of a flexible cable increases the flexibility and reliability of the connection and reduces the risk of connection interruption due to vibration or external force. The power amplifier component 4 is the core part of the sound amplification device. It is responsible for converting the processed audio and video signals into a Video signals are amplified to produce sound. To enhance stability and facilitate maintenance, the power amplifier assembly 4 is slidably engaged with the inner groove 3 of the housing 1 via a slider 5. This design allows the power amplifier assembly 4 to slide within a certain range, facilitating installation and removal. To attach the power amplifier assembly 4, the movable block 8 is pressed toward the inside of the notch 6 until the inner groove 3 is exposed. The two sets of protrusions 5 on the power amplifier assembly 4 are then aligned with the inner groove 3. The power amplifier assembly 4 is then rotated so that the protrusions 5 engage the inner groove 3 and secured with bolts. This completes the installation of the power amplifier assembly 4. When the protrusions 5 rotate into the inner groove 3, the spring 7 rebounds, causing the movable block 8 to seal the notch 6, thus completing the blockage. When the power amplifier assembly 4 receives the amplified signals from the signal conversion unit 12, it converts these signals into a powerful current, driving the speaker to produce clear, resonant sound. The sound is transmitted through the circular opening in the housing 1, achieving the audio and video amplification function.
