[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The appearance of the cartoon structure is novel, which can be used to attract different groups of people, especially children. The large silicone buttons are more suitable for mainstream children to learn and use, and prevent accidental touches. The outer wall of the bottom shell is provided with a gripping convex surface, which is more ergonomically designed and will not make you tired even after long-term use. The blue light-proof acrylic protection plate can effectively filter the blue light emitted by the large-screen color display, thereby reducing costs while achieving eye protection functions, improving the user experience and protecting human eyes.

[0026] 3. By using a rubber outer anti-collision shell, a thinner ABS plastic inner anti-collision shell and a steel support bar, the device can effectively disperse and offset the impact force when it is bumped. The outer anti-collision shell first absorbs the initial impact to reduce direct damage to internal components. Subsequently, the remaining impact force will be transmitted to the inner anti-collision shell and the support bar, causing them to deform and extend toward the bottom shell, thereby further absorbing and dispersing the impact energy, thereby improving the device's impact resistance, effectively protecting internal electronic components, reducing the risk of damage caused by bumps, and extending the service life of the device. This solves the problem in the prior art that when the device is bumped, the device will be damaged and there is a lack of protective structure for the inside and outer shell of the device;

[0027] 4. By sliding the speaker and the guide block in the guide groove, the positions of the speaker and the guide block can be alternately changed to correspond to the sound hole. At the same time, by driving the slide rod and the rotating rod, the left and right position and height of the cleaning plate on the guide block can be adjusted, and the cleaning plate can be inserted into the sound hole to effectively remove stubborn stains. When not in use, the rotating rod can be folded without affecting the use. The operation is simple, which improves the convenience of use and facilitates the cleaning of the sound hole to ensure the performance of the speed machine. At the same time, it prevents stains from entering the equipment and affecting the pronunciation device or internal structure, thereby extending the service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] Specifically, when the new calculator is in use: the appearance of the calculator is cartoon-decorated, and the appearance of the cartoon structure is novel, which can be used to attract different groups of people, especially children. It uses large silicone buttons, which are more suitable for mainstream children to learn and use, and prevent accidental touches. The outer wall of the bottom shell 2 is provided with a gripping protrusion 5, which is more ergonomically designed and will not make you tired even after long-term use. The acrylic protection plate 8 is made of anti-blue light material, which can effectively filter the blue light emitted by the color display 7, thereby reducing costs while realizing eye protection function. During the installation process, the battery body 18 will squeeze the limit block 17. Furthermore, the limit block 17 slides in the battery compartment 13, thereby squeezing the strong spring 15, and the strong spring 15 will be deformed by being squeezed. And elastic energy storage, the battery body 18 is completely embedded in the battery compartment 13, the strong spring 15 releases the elastic energy storage and pushes the limit block 17 back to its original position, thereby realizing the limit fixation of the battery body 18 to prevent the battery body 18 from falling off due to bumps or vibrations of the fast calculator, the outer anti-collision shell 19 is made of rubber, the inner anti-collision shell 20 is made of thinner ABS plastic material, and the support bar 21 is made of steel. When the equipment is bumped, it can effectively disperse and offset the impact force. The outer anti-collision shell 19 first absorbs the initial impact to reduce direct damage to internal components. The remaining impact force will be transmitted to the inner anti-collision shell 20 and the support bar 21. When the inner anti-collision shell 20, the support bar 21 and the outer anti-collision shell 19 are squeezed, they extend in the direction of the bottom shell 2, thereby further absorbing and dispersing the impact The impact energy is provided to provide double-layer protection and improve the impact resistance of the equipment, thereby reducing the risk of damage caused by bumps. If the sound hole 22 needs to be cleaned, it is only necessary to rotate the rotating rod 24 to keep the rotating rod 24 and the sliding rod 23 at the same horizontal plane, and then push the rotating rod 24 and the sliding rod 23 to slide in the surface shell 1. The sliding rod 23 will preferentially squeeze the cleaning plate 27 to slide in the guide block 28 through the slider 29 in the upward direction. At this time, the connecting plate 30 will adjust the angle. Since the loudspeaker 26 slides in the guide groove 32, that is, it can only move left and right, and cannot be lifted or lowered, it is pushed by the connecting plate 30 and moves to the left when the connecting plate 30 adjusts its angle. At the same time, the guide block 28 will slide on the traction rod 33. When the guide block 28 slides to a certain position, it is affected by The guide block 28 is moved by the guide plate 30, the loudspeaker 26 and the cleaning plate 27. When the guide block 28 moves to the fixed block structure inside the cleaning box 25 (not marked in the figure), it will be limited by the fixed block structure and cannot move. At this time, since the guide block 28 slides in the guide groove 32 higher than the original position, the traction rod 33 is bent and the guide block 28 is higher than the sliding rod 23. Therefore, the sliding rod 23 can continue to move.Thus, the cleaning plate 27 is squeezed and pushed to slide in the guide block 28 through the slider 29, and the densely distributed rods (not marked in the figure) on the top of the cleaning plate 27 are inserted into the sound hole 22 to clean the stubborn stains in the sound hole.
