Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to a waterproof loudspeaker. Background Technology

[0002] A loudspeaker is an electroacoustic transducer whose core function is to convert input electronic signals into audible sound signals. Loudspeakers operate based on electromagnetic induction and mechanical vibration. When an alternating current with a constantly changing direction passes through the coil, the coil vibrates continuously, which in turn drives the diaphragm to vibrate, thus producing sound.

[0003] Patent No. 202023131198.7 discloses a waterproof speaker. The device has a simple structure, multiple waterproof protections, and can drain water quickly, effectively preventing damage to the speaker.

[0004] However, existing waterproof loudspeakers use an electric telescopic rod to drive a pressure plate to squeeze the sponge, causing the water inside the sponge to drain out through the drainage holes on the enclosure. However, the internal diameter of the drainage holes is small, and since the drainage holes are exposed to the external environment for a long time, foreign objects such as dust and insects from the external environment can enter the drainage holes, causing blockage. This prevents the water inside the enclosure from flowing smoothly and affects the waterproof effect of the loudspeaker. Therefore, a waterproof loudspeaker is designed. Utility Model Content

[0005] In view of the problems in the background art, the present invention provides a waterproof speaker.

[0006] The technical solution adopted by this utility model to solve its technical problem is a waterproof loudspeaker, including a loudspeaker body, a shell fixed to the bottom of the loudspeaker body by screws, a shell cover for protecting the loudspeaker body fixed to one side of the shell by screws, a waterproof and breathable membrane A bonded to one side of the loudspeaker body, a waterproof and breathable membrane B for protecting the loudspeaker body symmetrically bonded to the inside of the shell, drainage holes and grooves symmetrically opened on the surface of the shell, a water immersion sensor fixed to the bottom of the inside of the shell by screws, a controller fixed to the inside of the shell by screws, a drive plate symmetrically slidably connected inside the shell, a sponge block B bonded to the outside of the drive plate, a through-hole plate glued to the side of the sponge block B away from the drive plate, a sponge block A bonded to one side of the through-hole plate, a cleaning component for cleaning the holes and grooves provided on the outside of the through-hole plate, and a drive component for moving the drive plate provided inside the shell.

[0007] By adopting the above technical solution, when water enters the housing, sponge block A inside the housing absorbs the water. After sponge block A becomes saturated, the excess water will seep into the other side of the perforated plate. Subsequently, sponge block B on the perforated plate absorbs the seeped water. When sponge block B absorbs too much water, the water inside sponge block B will come into contact with the water immersion sensor inside the housing, forming a conductive path within the water immersion sensor. This causes a decrease in circuit resistance and triggers an alarm signal. The signal is then transmitted to the controller inside the housing. The controller drives the drive assembly to move, which in turn drives the drive plate to move. The drive plate then presses down on sponge block B, squeezing the water inside sponge block B out through the perforated plate. After sponge block B is compressed and deformed, the drive plate presses down on the perforated plate through sponge block B, causing the perforated plate to press down on sponge block A. Consequently, the water inside sponge block A is squeezed out through the slots opened on the housing. At the same time, a cleaning component is provided on the perforated plate to clean the slots, preventing blockage and improving the waterproof performance of the speaker body.

[0008] Specifically, the outer surface of the drive plate is covered with a rubber pad that contacts the inner wall of the housing, and a drainage groove is provided on the top of the housing cover.

[0009] By adopting the above technical solution, the drainage groove opened on the top of the shell cover drains the water on the shell cover outward, preventing water from accumulating on the shell cover. When the drive board inside the shell moves, the rubber pad outside the drive board scrapes the inner wall of the shell, which facilitates the cleaning of water remaining in the shell and improves the waterproof performance of the speaker body.

[0010] Specifically, the cleaning assembly includes a rotating shaft, a torsion spring, and a tube block. The rotating shaft is rotatably connected to the outside of the through-hole plate, and the tube block is rotatably connected to the outside of the rotating shaft. A torsion spring is sleeved on the outside of the rotating shaft.

[0011] By adopting the above technical solution, when the perforated plate presses the sponge block A, the tube block on one side of the perforated plate enters the slot opened on the shell. Then, the outer surface of the tube block is attached to the inner wall of the slot, and the center of the tube block is open. As the perforated plate moves, the tube block rotates through the rotating shaft on the perforated plate, and the torsion spring installed outside the rotating shaft twists and compresses to generate elastic force, so that the tube block moves in the slot and pushes out the foreign objects adhering in the slot, thereby facilitating the cleaning of foreign objects in the slot.

[0012] Specifically, the drive assembly includes a dual-head motor, a threaded screw, a transmission block, and a support rod. The dual-head motor is fixed to the inner wall of the housing with screws, and the power output end of the dual-head motor is keyed to the threaded screw. The transmission block is externally threaded to the threaded screw.

[0013] By adopting the above technical solution, when the position of the transmission block needs to be adjusted, the double-headed motor inside the housing is driven by the controller to rotate the threaded screw, and the limiting block outside the transmission block slides in the corresponding limiting groove inside the housing, so that the transmission block moves axially outside the threaded screw, thereby facilitating the adjustment of the position of the transmission block.

[0014] Specifically, a support rod is welded to the outside of the transmission block, and the end of the support rod is welded to the outside of the drive plate.

[0015] By adopting the above technical solution, when the transmission block moves, the transmission block drives the support rod to move, which in turn pushes the drive plate, thus facilitating the adjustment of the drive plate position.

[0016] The beneficial effects of this utility model are:

[0017] The waterproof speaker of this utility model, when the through-hole plate presses the sponge block A, the tube block on one side of the through-hole plate enters the slot opened on the shell. Then the outer surface of the tube block is attached to the inner wall of the slot, and the center of the tube block is open. As the through-hole plate moves, the tube block rotates through the rotating shaft on the through-hole plate, and the torsion spring installed outside the rotating shaft twists and compresses to generate elastic force, so that the tube block moves in the slot and pushes out the foreign objects adhering in the slot, thereby facilitating the cleaning of foreign objects in the slot and allowing water in the shell to drain smoothly.

[0018] The waterproof speaker of this utility model has the following characteristics: when water comes into contact with the housing, the drainage groove on the housing cover drains the water to both sides. When water enters the housing, the sponge block A inside the housing absorbs the water. After the sponge block A is saturated, the excess water will seep into the other side of the perforated plate. Then, the sponge block B on the perforated plate absorbs the seeped water, thus facilitating the full absorption of water that has entered the housing. At the same time, as the drive plate moves, the rubber pad outside the drive plate scrapes the inner wall of the housing, pushing the water remaining in the housing to flow and be discharged, thereby improving the waterproof performance of the speaker body.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] To improve the waterproof performance of the speaker body 3, as one embodiment of this utility model, such as Figures 1 to 4 As shown, the waterproof speaker of this utility model includes a speaker body 3, a housing 7 fixed to the bottom of the speaker body 3 by screws, a cover 1 for protecting the speaker body 3 fixed to one side of the housing 7 by screws, a waterproof and breathable membrane A2 adhered to one side of the speaker body 3, a waterproof and breathable membrane B12 for protecting the speaker body 3 symmetrically adhered to the inside of the housing 7, drainage holes and grooves 6 symmetrically opened on the surface of the housing 7, a water immersion sensor 14 fixed to the bottom of the inside of the housing 7 by screws, a controller 4 fixed to the inside of the housing 7 by screws, a drive plate 11 symmetrically slidably connected inside the housing 7, a sponge block B10 adhered to the outside of the drive plate 11, a through-hole plate 9 glued to the side of the sponge block B10 away from the drive plate 11, a sponge block A8 adhered to one side of the through-hole plate 9, a cleaning component 13 for cleaning the holes and grooves 6 provided on the outside of the through-hole plate 9, and a drive component 18 for moving the drive plate 11 provided inside the housing 7.

[0027] During use, when water enters the housing 7, the sponge block A8 inside the housing 7 absorbs the water. After the sponge block A8 becomes saturated, the excess water will seep into the other side of the perforated plate 9. Subsequently, the sponge block B10 on the perforated plate 9 absorbs the seeped water. When the sponge block B10 absorbs too much water, the water inside the sponge block B10 will come into contact with the water immersion sensor 14 inside the housing 7. A conductive path is formed inside the water immersion sensor 14, causing the circuit resistance to drop and triggering an alarm signal. The signal is then transmitted to the controller 4 inside the housing 7, and the controller 4 drives the drive assembly. When component 18 moves, the drive assembly 18 drives the drive plate 11 to move. Then, the drive plate 11 presses the sponge block B10, and the water in the sponge block B10 is squeezed out through the through-hole plate 9. After the sponge block B10 is compressed and deformed, the drive plate 11 presses the through-hole plate 9 through the sponge block B10, which in turn presses the sponge block A8. As a result, the water in the sponge block A8 is squeezed out through the slots 6 opened on the housing 7. At the same time, a cleaning assembly 13 is provided on the through-hole plate 9 to clean the slots 6, so as to prevent the slots 6 from being blocked and improve the waterproof performance of the speaker body 3.

[0028] To improve the waterproof performance of the speaker body 3, for example, such as Figure 1 , Figure 2 As shown, the present invention also includes a rubber pad 23 that is bonded to the outer surface of the drive plate 11 and contacts the inner wall of the housing 7, and a drainage groove 5 is provided on the top of the housing cover 1.

[0029] During use, the drainage groove 5 on the top of the cover 1 drains the water out of the cover 1, preventing water from accumulating on the cover 1. When the drive plate 11 inside the housing 7 moves, the rubber pad 23 outside the drive plate 11 scrapes the inner wall of the housing 7, which facilitates the cleaning of water remaining in the housing 7 and improves the waterproof performance of the speaker body 3.

[0030] To clean foreign objects from the groove 6, for example, such as Figure 1 , Figure 2 As shown, the present invention also includes the cleaning assembly 13, which includes a rotating shaft 22, a torsion spring 21 and a tube block 20. The rotating shaft 22 is rotatably connected to the outside of the through-hole plate 9, and the tube block 20 is rotatably connected to the outside of the rotating shaft 22. The torsion spring 21 is sleeved on the outside of the rotating shaft 22.

[0031] When in use, when the through-hole plate 9 presses the sponge block A8, the tube block 20 on one side of the through-hole plate 9 enters the slot 6 opened on the housing 7. Then, the outer surface of the tube block 20 is attached to the inner wall of the slot 6, and the center of the tube block 20 is open. As the through-hole plate 9 moves, the tube block 20 rotates through the rotating shaft 22 on the through-hole plate 9, and the torsion spring 21 installed on the outside of the rotating shaft 22 is twisted and compressed to generate elastic force, which makes the tube block 20 move in the slot 6 and push out the foreign objects adhering in the slot 6, thereby facilitating the cleaning of foreign objects in the slot 6.

[0032] To adjust the position of the transmission block 16, for example, such as Figure 3 As shown, the present invention also includes the following: the drive assembly 18 includes a dual-head motor 19, a threaded screw 17, a transmission block 16 and a support rod 15. The dual-head motor 19 is fixed to the inner wall of the housing 7 with screws, and the power output end of the dual-head motor 19 is keyed to the threaded screw 17. The transmission block 16 is externally threaded to the threaded screw 17.

[0033] When the position of the transmission block 16 needs to be adjusted, the double-headed motor 19 inside the housing 7 is driven by the controller 4 to rotate the threaded screw 17. The limiting block outside the transmission block 16 slides in the corresponding limiting groove inside the housing 7, so that the transmission block 16 moves axially outside the threaded screw 17, thereby facilitating the adjustment of the position of the transmission block 16.

[0034] To adjust the position of the driver board 11, for example, such as Figure 3 As shown, the present invention also includes a support rod 15 welded to the outside of the transmission block 16, and the end of the support rod 15 is welded to the outside of the drive plate 11.

[0035] When in use, when the transmission block 16 moves, the transmission block 16 drives the support rod 15 to move, so that the support rod 15 pushes the drive plate 11, thereby facilitating the adjustment of the position of the drive plate 11.

[0036] In use, the drainage groove 5 at the top of the cover 1 drains water from the cover 1, preventing water accumulation. When water enters the housing 7, the sponge block A8 inside the housing 7 absorbs the water. After the sponge block A8 becomes saturated, excess water seeps into the other side of the perforated plate 9. Subsequently, the sponge block B10 on the perforated plate 9 absorbs the seeping water. When the sponge block B10 absorbs too much water, the water inside the sponge block B10 comes into contact with the water immersion sensor 14 inside the housing 7, forming a conductive path inside the water immersion sensor 14. The electrical circuit is interrupted, causing a decrease in circuit resistance and triggering an alarm signal. The signal is then transmitted to the controller 4 inside the housing 7. The dual-head motor 19 inside the housing 7, driven by the controller 4, rotates the threaded screw 17. The threaded screw 17 is mounted in the bearing seat of the housing 7 via a deep groove ball bearing, which is welded to the inner wall of the housing 7. A limiting block outside the transmission block 16 slides within a corresponding limiting groove inside the housing 7, causing the transmission block 16 to move axially outside the threaded screw 17. Subsequently, a support rod 15 on one side of the transmission block 16 pushes the drive plate 11 to move. The drive plate 11 presses the sponge block B10, squeezing the water inside the sponge block B10 out through the through-hole plate 9. After the sponge block B10 is compressed and deformed, the drive plate 11 presses the through-hole plate 9 through the sponge block B10, causing the through-hole plate 9 to press the sponge block A8. As a result, the water inside the sponge block A8 is squeezed out through the slot 6 opened on the housing 7, and the slot 6 is inclined downward. At the same time, the tube block 20 on one side of the through-hole plate 9 enters the slot 6 opened on the housing 7. Subsequently, the outer surface of the tube block 20 is attached to the inner wall of the slot 6, and the center of the tube block 20 is open. As the through-hole plate 9 moves, the tube block 20 rotates via the rotating shaft 22 on the through-hole plate 9. The torsion spring 21 installed outside the rotating shaft 22 twists and compresses to generate elastic force, causing the tube block 20 to move within the slot 6, pushing out foreign objects adhering to the slot 6. This facilitates the cleaning of foreign objects within the slot 6, preventing the slot 6 from becoming blocked, and allowing water entering the housing 7 to drain smoothly. Additionally, the rubber pad 23 outside the drive plate 11 scrapes the inner wall of the housing 7, cleaning the water remaining in the housing 7 and improving the waterproof performance of the speaker body 3.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
