Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Embodiment 1

[0020] See also Figure 1-4A sound speaker with a dustproof structure comprises a shell 1, a sound speaker body 2 is fixedly connected to the inside of the shell 1, a dustproof mechanism 3 is arranged inside the shell 1, the dustproof mechanism 3 comprises a perforated plate 31, the perforated plate 31 is fixedly connected to the inner wall of the shell 1, a dustproof plate 32 is slidably connected to the inside of the perforated plate 31, a push block 33 is slidably connected to the inner wall of the dustproof plate 32, the shape and size of the push block 33 match the hole on the perforated plate 31, and the cross section of the push block 33 is a trapezoid, through the push block 33 The setting of the size and shape ensures that the push block 33 can enter the hole when it is at the same horizontal position as the hole on the punching plate 31, so as to push out the dust accumulated inside the hole of the punching plate 31 to achieve a cleaning effect. The push block 33 is elastically connected to the dustproof plate 32 through a spring 1 39. A spring 2 34 is fixedly connected to the top of the dustproof plate 32. One end of the spring 2 34 away from the dustproof plate 32 is fixedly connected to the inner wall of the punching plate 31. An electromagnet 35 is arranged in the upper inner wall of the punching plate 31. The dustproof plate 32 is provided with holes of the same size and shape as the punch plate 31, and when the electromagnet 35 is energized, the holes on the dustproof plate 32 and the holes on the punch plate 31 are at the same horizontal position. By setting the holes on the dustproof plate 32, it is ensured that after the device is started, the sound of the audio body 2 can be transmitted through the holes to prevent the sound transmission effect from being affected. An iron rod 36 is fixedly connected to the top of the dustproof plate 32, and a drawer 37 is slidably connected to the inner wall of the shell 1, and the drawer 37 is arranged below the punch plate 31. A cleaning assembly 38 is provided on the side of the perforated plate 31 away from the audio body 2. Through the joint action of the iron rod 36, the electromagnet 35 and the spring 34, the holes on the dustproof plate 32 and the holes on the perforated plate 31 are in the same plane after the power of the device is turned on, preventing the sound from being blocked and affecting the sound transmission effect. When the power of the device is turned off, the pushing block 33 and the holes on the perforated plate 31 are in the same plane, achieving the effect of preventing dust from contacting the audio body 2 while cleaning the inside of the holes on the perforated plate 31.

[0021] During use, when the user needs to use the audio body 2, the user first starts the power supply of the device. At this time, the electromagnet 35 is energized, so that the electromagnet 35 generates a magnetic force, so that the iron rod 36 moves upward under the suction force of the electromagnet 35, and drives the dustproof plate 32 to move upward. At this time, the holes on the dustproof plate 32 and the holes on the perforated plate 31 are exactly at the same horizontal position, and the sound of the audio body 2 is transmitted through the holes. When the use is over, the staff turns off the power supply of the device. At this time, the electromagnet 35 is not energized, so no suction force is generated on the iron rod 36. At this time, the dustproof plate 32 moves downward under the combined action of gravity and spring 2 34, so that the pushing block 33 and the holes on the perforated plate 31 are at the same horizontal position. At this time, the pushing block 33 moves outward under the drive of spring 1 39, thereby pushing the dust accumulated inside the holes of the perforated plate 31, thereby achieving the cleaning effect of the perforated plate 31.

[0022] Embodiment 2

[0023] See also Figure 1-4 On the basis of the first embodiment, the cleaning assembly 38 includes an air pressure tube 381, the air pressure tube 381 is arranged inside the shell 1, the air pressure tube 381 is arranged inside the perforated plate 31, the air pressure tube 381 is connected to the air bag 387, the inner wall of the air pressure tube 381 is slidably connected to a push block 382, ​​the inner wall of the shell 1 is slidably connected to a brush 383, the brush handle of the brush 383 is slidably connected to a trapezoidal block 384, and the trapezoidal block 384 is elastically connected to the brush handle of the brush 383 through a spring 385. Then, the airbag 387 is arranged inside the perforated plate 31, and the elastic force of the second spring 34 and the gravity of the dustproof plate 32 are greater than the elastic force of the third spring 385. The setting position of the airbag 387 ensures that the dustproof plate 32 can squeeze the airbag 387 when it is not affected by the magnetic force. The size setting of the second spring 34 and the gravity of the dustproof plate 32 and the elastic force of the third spring 385 ensures that when the airbag 387 is squeezed, the trapezoidal block 384 can be squeezed out of the card hole 386. The inner wall of the shell 1 is provided with The clamping hole 386 and the push block 382 are at the same horizontal position, and the sliding distance of the push block 382 is greater than the depth of the clamping hole 386. By setting the positions of the clamping hole 386 and the push block 382, ​​it is ensured that the push block 382 can push the trapezoidal block 384 after it moves. By comparing the depth of the clamping hole 386 with the sliding distance of the push block 382, ​​it is ensured that the push block 382 can push the trapezoidal block 384 to a position away from the clamping hole 386, so as to achieve the effect of releasing the limit. 3 The dust on the surface of the perforated plate 31 is cleaned, and when the power of the device is on, the brush 383 cannot move under the joint action of the trapezoidal block 384, the spring three 385 and the clamping hole 386. After the power is turned off, the dustproof plate 32, the air bag 387, the air pressure tube 381 and the push block 382 jointly release the limit of the brush 383, so as to prevent the dust from contacting the audio body 2 through the perforated plate 31 during the cleaning process, thereby affecting the service life of the audio.

[0024] During use, based on the first embodiment, when the audio body 2 is in the power-on state, the brush 383 is at the bottom of the shell 1 under the action of gravity, and the trapezoidal block 384 is pushed by the spring three 385 so that the trapezoidal block 384 is inside the card hole 386. At this time, the user cannot move the brush 383. When the power of the device is turned off, the dustproof plate 32 moves downward and squeezes the airbag 387, so that the gas inside the airbag 387 enters the air pressure tube 381, thereby increasing the air pressure inside the air pressure tube 381, so that the push block 382 moves outward and pushes the trapezoidal block 384, so that the trapezoidal block 384 moves out of the card hole 386. Therefore, the limit of the brush 383 is released at this time, and the staff can clean the outer wall of the perforated plate 31 by moving the brush 383, and collect the swept dust through the drawer 37 for easy cleaning.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
