Abstract
Description
Technical Field
[0001] This utility model relates to the field of voice coil loudspeaker technology with a transparent diaphragm, specifically a voice coil loudspeaker with a transparent diaphragm. Background Technology
[0002] Existing voice coil loudspeakers typically use paper, metal, or polymer films as diaphragms. For existing transparent diaphragm loudspeakers, dust not only affects sound propagation but also damages their visual appeal and light transmission.
[0003] Currently, most voice coil loudspeakers with transparent diaphragms rely solely on external dust covers for protection and lack efficient online automatic cleaning structures. When it is necessary to clean the diaphragm surface, it is often necessary to manually disassemble the loudspeaker housing or use external tools, which is cumbersome and carries the risk of scratching the diaphragm.
[0004] Therefore, it is necessary to design a voice coil loudspeaker with a transparent diaphragm to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a voice coil loudspeaker with a transparent diaphragm to solve the technical problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a voice coil loudspeaker with a transparent diaphragm, comprising a loudspeaker housing, a fixed top ring fixedly connected to the top of the loudspeaker housing, a mounting ring threadedly connected to the top of the fixed top ring, a connecting block fixedly connected to the top of the mounting ring, a mounting block fixedly connected to the top of the connecting block, a small servo motor fixedly connected to the top of the mounting block, a first rotating shaft fixedly connected to the output shaft of the small servo motor, a second rotating shaft movably inserted into the bottom of the first rotating shaft, a cleaning component fixedly connected to the bottom of the second rotating shaft, a spring fixedly connected between the top of the second rotating shaft and the top of the inner cavity of the first rotating shaft, a pin fixedly inserted into the top of the second rotating shaft, two symmetrical sliding openings opened on the outer surface of the first rotating shaft, and the two ends of the pin slidably disposed inside the two sliding openings, and a sleeve plate rotatably sleeved on the outer surface of the second rotating shaft via a bearing, a pin fixedly connected to the top of the sleeve plate, and a push block fixedly connected to the top of the pin.
[0007] Preferably, the top of the plug is slidably inserted into the interior of the connecting block and the mounting block, and the top of the plug protrudes from the exterior of the mounting block, and the push block is fixed to the end of the plug outside the mounting block.
[0008] Preferably, a gap is formed between the bottom end of the second rotating shaft and the bottom end of the first rotating shaft, and the sleeve is fitted between the bottom end of the first rotating shaft and the bottom end of the second rotating shaft.
[0009] Preferably, the top end of the spring is fixed to the top of the inner cavity of the first rotating shaft, and the bottom end of the spring is fixed to the top end of the second rotating shaft.
[0010] Preferably, both ends of the insertion post are fixedly connected to limiting plates, and the adjacent sides of the two limiting plates are in contact with the outer surface of the first rotating shaft.
[0011] Preferably, the cleaning component is U-shaped, and both bottom ends of the cleaning component are in contact with the outer surface of the top diaphragm of the speaker housing, and the connecting block is arc-shaped.
[0012] The technical solution provided by this utility model has the following advantages compared with the prior art:
[0013] This invention achieves automatic adhesion and rotation cleaning of the transparent diaphragm surface by setting an arc-shaped connecting block and a rotatable cleaning component on the outside of the speaker, in conjunction with a small servo motor, a lifting mechanism for the sleeve, and a spring return structure. This efficiently removes dust and impurities from the diaphragm surface, avoiding any impact on sound quality and light transmission. Meanwhile, in the non-cleaning state, the cleaning component maintains a gap with the diaphragm through spring retraction, preventing interference with the diaphragm's normal vibration. The reasonable structural design improves the speaker's ease of use and stability while extending the service life of the transparent diaphragm. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0019] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0020] Please see Figure 1-3 This utility model provides a voice coil loudspeaker with a transparent diaphragm, including a loudspeaker housing 1. A fixing top ring 2 is fixedly connected to the top of the loudspeaker housing 1. A mounting ring 3 is threadedly connected to the top of the fixing top ring 2. A connecting block 4 is fixedly connected to the top of the mounting ring 3. A mounting block 5 is fixedly connected to the top of the connecting block 4. A small servo motor 6 is fixedly connected to the top of the mounting block 5. A first rotating shaft 9 is fixedly connected to the output shaft of the small servo motor 6. A second rotating shaft 10 is movably inserted into the bottom of the first rotating shaft 9. A cleaning component 11 is fixedly connected to the bottom of the second rotating shaft 10. A spring 15 is fixedly connected between the top of the second rotating shaft 10 and the top of the inner cavity of the first rotating shaft 9. A pin 13 is fixedly inserted into the top of the second rotating shaft 10. Two symmetrical sliding openings are provided on the outer surface of the first rotating shaft 9, and the two ends of the pin 13 slide respectively. The interior has two sliding openings, and the outer surface of the second rotating shaft 10 is rotatably sleeved with a sleeve 12 via a bearing. The top of the sleeve 12 is fixedly connected to a plug post 8, and the top of the plug post 8 is fixedly connected to a button 7. When the speaker housing 1 is in use, because dust easily adheres to the transparent diaphragm, when dust cleaning is required, the small servo motor 6 is turned on, and the first rotating shaft 9 is rotated. By inserting the plug post 13, the second rotating shaft 10 drives the cleaning component 11 to rotate. Then, by pressing the button 7, the bottom ends of the cleaning component 11 are made to fit with the transparent diaphragm, thereby performing the rotation cleaning work. In daily use, the elasticity of the spring 15 is used to retract the cleaning component 11, so that the bottom of the cleaning component 11 does not fit with the transparent diaphragm, thereby avoiding the vibration of the transparent diaphragm being affected by the adhesion of the cleaning component 11.
[0021] To facilitate limiting the sliding of the plug post 8, the top of the plug post 8 is slidably inserted into the interior of the connecting block 4 and the mounting block 5, and the top of the plug post 8 protrudes outside the mounting block 5. The push block 7 is fixed to the end of the plug post 8 outside the mounting block 5.
[0022] In order to facilitate the lifting and lowering of the second rotating shaft 10 by the lifting and lowering of the sleeve 12, the bottom end of the second rotating shaft 10 is formed with the bottom end of the first rotating shaft 9, and the sleeve 12 is sleeved between the bottom end of the first rotating shaft 9 and the bottom end of the second rotating shaft 10.
[0023] In order to provide elastic lifting of the second rotating shaft 10, the top end of the spring 15 is fixed to the top of the inner cavity of the first rotating shaft 9, and the bottom end of the spring 15 is fixed to the top end of the second rotating shaft 10.
[0024] Furthermore, in order to improve the stability of the elastic lifting of the second rotating shaft 10, both ends of the insertion post 13 are fixedly connected to limiting pieces 14, and the adjacent sides of the two limiting pieces 14 are in contact with the outer surface of the first rotating shaft 9.
[0025] To facilitate regular cleaning of the outer surface of the transparent diaphragm, the cleaning component 11 is U-shaped, and both ends of the bottom of the cleaning component 11 are in contact with the outer surface of the top diaphragm of the speaker housing 1, and the connecting block 4 is arc-shaped.
[0026] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0027] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
[0028] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
