[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-4 This utility model provides a technical solution for a knob-type suction cup wall-mounted sound box: it includes a sound box body 1 and a fixing block 2, wherein the fixing block 2, in cooperation with the connecting block 4, enables the rapid fixing and disassembly of the sound box body 1. The fixing block 2 is located on the outside of the sound box body 1, and two plug-in components 3 are provided inside the fixing block 2. The plug-in components 3 include a telescopic rod 301 installed inside the fixing block 2, wherein the telescopic rod 301 provides guiding support for the movement of the movable block 303, restricts the movement trajectory of the movable block 303, and ensures that the plug 304 is aligned with the slot 5. A spring 302 is sleeved on the outer wall of the telescopic rod 301, wherein the spring 302 uses its own elastic deformation to provide a reset force, driving the plug 304 to engage or disengage from the slot 5. The telescopic end of the telescopic rod 301 is connected to the movable block 303, and the outer wall of the movable block 303 is connected to the plug 304, two sliders 305 and a connecting rod 306. The interior of the fixing block 2 is provided with a sliding groove 6 that matches the two sliders 305.
[0018] The outer wall of the sound box body 1 is connected to a connecting block 4, which is inserted into the inside of the fixed block 2. The inside of the connecting block 4 is provided with a slot 5 that matches the insert block 304. Each connecting rod 306 has an end that passes through the fixed block 2 away from the movable block 303 and is fitted with an anti-slip sleeve 307. The anti-slip sleeve 307 is fitted on the exposed end of the connecting rod 306 to increase the friction between the hand and the connecting rod 306, prevent slippage during operation, and improve the ease of disassembly and assembly. The bottom surface of the fixed block 2 is provided with a suction cup body 7. An adjustment head 8 and a connector 9 are installed on the suction cup body 7. By rotating the adjustment head 8, the internal air pressure of the suction cup is adjusted to enhance the suction force of the suction cup and prevent the device from accidentally falling off. The upper end of the connector 9 is connected to the bottom surface of the fixed block 2.
[0019] The main body 1 of the sound box is equipped with a control module 10, an energy storage module 12, and a button 11. The control module 10 is the electronic control core of the device, responsible for receiving the trigger signal from the button 11, driving the speaker 15 to produce sound, and the indicator light 16 to display the status. The energy storage module 12 serves as the mounting carrier for the battery 13 and integrates a charging port 14, which protects the battery, regulates the circuit, and ensures the safety and stability of the power supply system. The energy storage module 12 contains the battery 13 and has a charging port 14. The control module 10 is equipped with a speaker 15, an indicator light 16, and a power switch 17. The speaker 15 receives the drive signal from the control module 10 and plays the voice that matches the content of the poster, realizing the early education sound function.
[0020] The working principle of this utility model is as follows: In use, firstly, by moving the anti-slip sleeve 307 at the end of the connecting rod 306, the movable block 303 drives the telescopic rod 301 to compress the spring 302, causing the insert block 304 to retract. After inserting the connecting block 4 of the sound box body 1 into the fixed block 2, the connecting rod 306 is released. The spring 302's rebound force pushes the movable block 303 back to its original position, and the insert block 304 is locked into the slot 5 of the connecting block 4 to complete the fixation. The sliders 305 on both sides of the movable block 303 slide along the sliding groove 6 in the fixed block 2 to achieve guidance and limitation; the fixed block 2 The suction cup body 7 on the bottom adheres to the flat surface. Rotating the adjustment head 8 adjusts the internal air pressure of the suction cup to enhance the adsorption stability. The connector 9 securely connects the fixing block 2 and the suction cup body 7. The battery 13 in the energy storage module 12 powers the electronic system. The charging port 14 can replenish the battery 13. Pressing the button 11 on the sound box body 1 transmits the signal to the control module 10. The control module 10 drives the speaker 15 to emit voice matching the content of the poster. The power switch 17 controls the start and stop of the electronic system. The indicator light 16 displays the power-on and working status of the device in real time.
[0021] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
