Description

Technical Field

[0001] The present invention relates to the technical field of speaker casings, and more specifically, to a miniature high-pressure waterproof speaker. Background Art

[0002] For a miniature high-pressure waterproof speaker, the high-pressure water protection operation is mainly carried out through a waterproof speaker casing. The primary function is to protect the electronic components, coils, and diaphragms inside the speaker from moisture erosion. Moisture is one of the main causes of electronic device failures. Once moisture penetrates into the speaker, it can cause component short circuits, corrosion, or damage, thereby affecting the performance and lifespan of the speaker. Therefore, the waterproof casing of the speaker can effectively isolate moisture and ensure that the speaker can still work properly in humid or multi-water environments. For this reason, the speaker needs an external waterproof casing to provide a protection function.

[0003] In the existing published literature, the patent with the patent publication number CN113286210A discloses a speaker box with good waterproof effect. Through the setting of a water scraping component, the device can scrape off the condensed water droplets inside the speaker box for collection, further improving the moisture absorption capacity of the device. In this embodiment, by integrating the moisture absorption component and the water scraping component, the device can carry out waterproofing from the inside of the speaker box, improving the waterproof ability of the device. However, this technology still has the following defects; When a miniature speaker is accidentally impacted by a high-pressure water body, although it can drain water through the curved holes around the casing to reduce the pressure and prevent the high-pressure penetration of the water body into the sealed gaps of the casing, the holes of the casing are curved holes, and at the same time, the casing holes are open for a long time. When there is no water contact, the curved holes will be blocked by dust in the outdoor environment. In this way, when the speaker casing is impacted by a high-pressure water body, it is difficult to quickly achieve large-area unobstructed drainage, difficult to reduce the water penetration pressure at the edge of the casing, and it is extremely easy for the water body to penetrate into the speaker. The waterproof effect of the miniature speaker casing is poor. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides the following technical solutions: A miniature high-pressure waterproof speaker, including a sealed casing, a docking casing, and a protective casing. The docking casing is fixed on one side of the sealed casing, and the protective casing is fixed at one side edge position of the docking casing. A sliding frame is fixedly connected to one side of the docking casing and close to the middle position thereof. An in-casing lateral pressure relief and waterproof mechanism is installed inside the sliding frame; the in-casing lateral pressure relief and waterproof mechanism includes a miniature motor fixedly installed inside the sliding frame. The output end of the miniature motor is fixedly connected to a linkage screw rod. Two socket blocks are threadedly connected to the outer wall of the linkage screw rod. The two threads on the outer wall of the linkage screw rod are opposite and symmetrically arranged. Both of the socket blocks are slidably connected to the sliding frame.

[0005] One side of each socket block is fixedly connected with a linkage bar, one end of the linkage bar is fixedly connected with a frame bar, one side of the frame bar is fixedly connected with a horizontal waterproof strip, and both of the horizontal waterproof strips are slidably connected with the sealing machine housing; both the top end and the bottom end of the socket block are fixedly connected with connecting bars, and a machine housing vertical pressure relief and waterproof mechanism is arranged on one side of the connecting bar; a machine housing waterproof treatment assembly is arranged at the top end of the inner wall of the sealing machine housing.

[0006] Preferably, the micro motor is used to drive the linkage screw to rotate, the linkage screw is rotatably connected with the sliding frame, the two frame bars are symmetrically arranged with respect to the sealing machine housing, and there is a gap between the frame bar and the sealing machine housing. One side of the outer wall of the sealing machine housing is inserted with a connecting wire, and one end of the connecting wire is fixedly connected with a power-on plug. A permanent magnet is fixedly installed on one side of the inner wall of the sealing machine housing, a voice coil is arranged outside the permanent magnet, and one side of the voice coil is fixedly connected with a vibration film; the vibration film is fixedly connected with the sealing machine housing; a sealing ring is fixedly connected to the other side of the sealing machine housing, and the voice coil is electrically connected with the connecting wire. A micro controller is installed on one side of the inner wall of the protective housing, and the micro controller is fixedly connected with the protective housing.

[0007] When the present technology is in use, the micro motor drives the linkage screw to rotate, the socket block moves leftward, and the other socket block moves rightward. The linkage bar drives the frame bar to move leftward, and the horizontal waterproof strip moves out of the inside of the sealing machine housing from the left, while the other horizontal waterproof strip moves out of the inside of the sealing machine housing from the right, so that the two horizontal waterproof strips can open the drain openings at the horizontal two sides, avoiding blockage at the two horizontal drainage positions, preventing high-pressure water flow from penetrating into the connection between the vibration film and the sealing machine housing, and quickly discharging the water.

[0008] Preferably, the machine housing vertical pressure relief and waterproof mechanism includes a linkage column fixedly arranged on one side of the connecting bar; a sleeve rod is rotatably connected to the outer wall of the linkage column, a hinge column is rotatably connected to the inner wall of the sleeve rod and away from the linkage column, one end of the hinge column is fixedly connected with a hinge push rod, and the sleeve rod is rotatably connected with the hinge push rod.

[0009] On one side of the outer wall of one of the articulated push rods, an induction block is fixedly connected. A guide sleeve block is slidably connected to the outer wall of the articulated push rod. The guide sleeve block is fixedly connected to the docking machine housing. A positioning distance sensor is fixedly installed on one side of one of the guide sleeve blocks. The top end of the articulated push rod is fixedly connected to a moving strip. One end of the moving strip is fixedly installed with a pressing strip. A vertical waterproof strip is fixedly connected to the lower surface of the pressing strip. A rubber frame strip is fixedly connected to the outer wall of the vertical waterproof strip. Both the pressing strip and the rubber frame strip are slidably connected to the sealing machine housing. The center point of the articulated column is higher than the center point of the linkage column. One side surface of the positioning distance sensor and one side surface of the induction block are in the same vertical plane.

[0010] When the present technology is in use, the socket block drives the two connecting strips to move left synchronously. The linkage column drives the bottom end of the sleeve rod to move left. At the same time, the other articulated column moves down. The sleeve rod drives the articulated push rod to move up. The articulated push rod drives the moving strip to move up. The pressing strip drives the vertical waterproof strip to move up. The vertical waterproof strip drives the rubber frame strip to move up. The rubber frame strip slides up along the inner wall of the sealing machine housing. The other rubber frame strip moves down. When the distance value sensed by the positioning distance sensor is the same as the distance set by the microcontroller, the microcontroller turns off the micro motor. In this way, two vertical drainage ports can be opened at the top and bottom of the inner wall of the sealing machine housing. The drainage area at the top and bottom of the inner wall of the sealing machine housing is greatly increased, and the water flow at the top and bottom of the inner wall of the sealing machine housing can be quickly relieved and discharged.

[0011] Preferably, the housing waterproof treatment assembly includes an immersion sensor fixedly arranged at the top end of the inner wall of the sealing machine housing. A pressure sensor is arranged on one side of the immersion sensor, and the pressure sensor is fixedly connected to the sealing machine housing. A reinforcing sleeve block is fixedly installed at a position near the top end of the outer wall of the pressure sensor. The reinforcing sleeve block is fixedly connected to the immersion sensor. A support block is arranged on one side of the pressure sensor. Both the sealing machine housing and the reinforcing sleeve block are fixedly connected to the support block, and the support block is used to support the reinforcing sleeve block.

[0012] When the present technology is in use, the support block supports the reinforcing sleeve block, and the reinforcing sleeve block supports the immersion sensor. When a high-pressure water body impacts the vibration film until it reaches the edge position of the connection between the sealing machine housing and the vibration film, the immersion sensor senses that there is water flow at the edge position of the connection between the sealing machine housing and the vibration film. At the same time, the pressure sensor senses the pressure of the water flow impact.

[0013] The technical effects and advantages of the present invention: 1. Through the lateral pressure relief and waterproof mechanism of the casing, the present invention can immediately detect the problem of water flow impact and accumulation at the edge of the connection between the sealed casing and the vibration film. The micro motor drives the linkage screw to rotate. Under the action of the thread transmission force, the two socket blocks move away from each other. One socket block moves to the left, and the other socket block moves to the right. The lateral waterproof strip moves out of the sealed casing from the left, and the other lateral waterproof strip moves out of the sealed casing from the right. The two lateral waterproof strips can open the drainage ports at the lateral positions on both sides, greatly increasing the drainage area on both sides of the inner wall of the sealed casing. At the same time, when there is no rain, the two lateral waterproof strips fill the positions on both sides of the inner wall of the sealed casing, thus preventing dust and impurities from blocking the lateral drainage ports. Therefore, when the sealed casing is impacted by high-pressure water, it can quickly achieve smooth lateral drainage over a large area, greatly reducing the water penetration pressure at the edge between the sealed casing and the vibration film, and improving the waterproof effect of the sealed casing on the micro speaker.

[0014] 2. By using the vertical pressure relief and waterproof mechanism of the casing, when the socket block moves to the left, the socket block will drive the two connecting strips to move left synchronously. The two connecting strips respectively drive the two linkage columns to move left synchronously. The sleeve rod drives the articulated column to move upward, and at the same time, the other articulated column moves downward. The rubber frame strip slides upward along the inner wall of the sealed casing, and the other rubber frame strip moves downward, capable of opening two vertical drainage ports at the top and bottom of the inner wall of the sealed casing. When there is no water, the two vertical waterproof strips are closed in the two vertical drainage ports, thus preventing dust and impurities from blocking the vertical drainage ports, quickly achieving smooth vertical drainage over a large area, greatly reducing the water penetration pressure at the edge between the sealed casing and the vibration film, and improving the waterproof effect of the sealed casing on the micro speaker.

[0015] 3. The present invention adopts a casing waterproof treatment component. The support block supports and reinforces the sleeve block, and the reinforced sleeve block supports the pressure sensor and the immersion sensor. When the high-pressure water impacts the vibration film and flows to the edge of the connection between the sealed casing and the vibration film, the immersion sensor senses that there is water flow at the edge of the connection between the sealed casing and the vibration film, and the pressure sensor senses the pressure of the water flow impact. In this way, when the sealed casing is impacted by high-pressure water, it can be promptly aware of it, thus quickly achieving large-area lateral pressure relief drainage and large-area vertical pressure relief drainage, and improving the waterproof effect of the sealed casing on the micro speaker.

[0016] According to the mutual influence of the above multiple functions, first, when the sealed housing is impacted by high-pressure water, it can be aware of it in time. Secondly, the horizontal waterproof strip moves out to the left from the inside of the sealed housing, and the other horizontal waterproof strip moves out to the right from the inside of the sealed housing. At the same time, the rubber frame strip slides upward along the inner wall of the sealed housing, and the other rubber frame strip moves downward. Finally. In summary, when the sealed housing is impacted by high-pressure water, it can quickly achieve large-area unobstructed drainage horizontally and quickly achieve large-area unobstructed drainage vertically. At the same time, when there is no water, dust and impurities will not enter the horizontal drainage holes and vertical drainage holes, greatly reducing the water penetration pressure at the edge position between the sealed housing and the vibration film, and the waterproof effect of the sealed housing on the micro speaker is better.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] As shown in the attached Figure 1 - attached Figure 10 As shown in the figure, a micro high-pressure waterproof speaker is provided with a housing horizontal pressure relief and waterproof mechanism, a housing vertical pressure relief and waterproof mechanism, and a housing waterproof treatment component. The settings of each mechanism and component can quickly achieve smooth drainage in a large area horizontally and quickly achieve smooth drainage in a large area vertically. At the same time, when there is no water, dust and impurities will not enter the horizontal drainage holes and vertical drainage holes, greatly reducing the water penetration pressure at the edge position between the sealed housing 1 and the vibrating diaphragm 15. The waterproof effect of the sealed housing 1 on the micro speaker is better. The specific structural settings of each mechanism and component are as follows.

[0030] In this embodiment, as shown in the attached Figure 1 - attached Figure 4 As shown in the figure, the docking housing 2 is fixed on one side of the sealed housing 1, the protective housing 3 is fixed at the edge position on one side of the docking housing 2, a sliding frame 4 is fixedly connected to one side of the docking housing 2 and close to the middle position thereof, and a housing horizontal pressure relief and waterproof mechanism is installed inside the sliding frame 4; the housing horizontal pressure relief and waterproof mechanism includes a micro motor 5 fixedly installed inside the sliding frame 4, the output end of the micro motor 5 is fixedly connected with a linkage screw 6, two socket blocks 7 are threadedly connected to the outer wall of the linkage screw 6, the threads on both sides of the outer wall of the linkage screw 6 are opposite and symmetrically arranged, and both socket blocks 7 are slidably connected to the sliding frame 4.

[0031] On one side of each socket block 7, a linkage bar 8 is fixedly connected. At one end of the linkage bar 8, a frame bar 9 is fixedly connected. On one side of the frame bar 9, a horizontal waterproof strip 10 is fixedly connected. Both horizontal waterproof strips 10 are slidably connected to the sealing machine housing 1. At the top and bottom of the socket block 7, connection bars 18 are fixedly connected. On one side of the connection bar 18, a vertical pressure relief and waterproof mechanism for the machine housing is provided. At the top of the inner wall of the sealing machine housing 1, a waterproof treatment assembly for the machine housing is provided. The micro motor 5 is used to drive the linkage screw 6 to rotate. The linkage screw 6 is rotatably connected to the sliding frame 4. The two frame bars 9 are symmetrically arranged with respect to the sealing machine housing 1, and there is a gap between the frame bar 9 and the sealing machine housing 1.

[0032] In this embodiment, as shown in the attached Figure 1 - attached Figure 6 figure, on one side of the outer wall of the sealing machine housing 1, a connecting wire 11 is inserted. At one end of the connecting wire 11, a power plug 12 is fixedly connected. On one side of the inner wall of the sealing machine housing 1, a permanent magnet 13 is fixedly installed. Outside the permanent magnet 13, a voice coil 14 is provided. On one side of the voice coil 14, a vibrating diaphragm 15 is fixedly connected. The vibrating diaphragm 15 is fixedly connected to the sealing machine housing 1. On the other side of the sealing machine housing 1, a sealing ring 16 is fixedly connected. The voice coil 14 is electrically connected to the connecting wire 11. So that when sound needs to be amplified, the voice coil 14 is powered through the connecting wire 11. A changing magnetic field appears around the voice coil 14. The changing magnetic field interacts with the constant magnetic field provided by the permanent magnet 13, causing the voice coil 14 to be affected by the magnetic force. The voice coil 14 will drive the vibrating diaphragm 15 to perform a vibrating operation. The vibrating diaphragm 15 vibrates to push the surrounding air to vibrate, forming sound waves to achieve the sound amplification operation.

[0033] On one side of the inner wall of the protective shell 3, a microcontroller 17 is installed. The microcontroller 17 is fixedly connected to the protective shell 3. So that the micro motor 5 can be immediately started through the microcontroller 17. The micro motor 5 drives the linkage screw 6 to rotate, facilitating the rotation operation of the linkage screw 6.

[0034] In this embodiment, as shown in the attached Figure 5 - attached Figure 8 figure, the vertical pressure relief and waterproof mechanism for the machine housing includes a linkage column 19 fixedly arranged on one side of the connection bar 18. The outer wall of the linkage column 19 is rotatably connected to a sleeve rod 20. Inside the sleeve rod 20 and at a position far from the linkage column 19, a hinge column 21 is rotatably connected. At one end of the hinge column 21, a hinge push rod 22 is fixedly connected. The sleeve rod 20 is rotatably connected to the hinge push rod 22. On one side of the outer wall of one of the hinge push rods 22, an induction block 23 is fixedly connected. The outer wall of the hinge push rod 22 is slidably connected to a guiding sleeve block 24. The guiding sleeve block 24 is fixedly connected to the docking machine housing 2. On one side of one of the guiding sleeve blocks 24, a positioning distance sensor 25 is fixedly installed. At the top of the hinge push rod 22, a moving bar 26 is fixedly connected.

[0035] One end of the moving bar 26 is fixedly installed with a pressing strip 27. The lower surface of the pressing strip 27 is fixedly connected with a vertical waterproof strip 28. The outer wall of the vertical waterproof strip 28 is fixedly connected with a rubber frame strip 29. Both the pressing strip 27 and the rubber frame strip 29 are slidably connected to the sealed housing 1. The center point of the hinge column 21 is higher than the center point of the linkage column 19. One side surface of the positioning distance sensor 25 and one side surface of the induction block 23 are in the same vertical plane.

[0036] In this embodiment, as shown in the Figure 9 - Figure 10 figures, the housing waterproof treatment assembly includes an immersion sensor 30 fixedly arranged at the top end of the inner wall of the sealed housing 1; a pressure sensor 31 is arranged on one side of the immersion sensor 30, and the pressure sensor 31 is fixedly connected to the sealed housing 1. A reinforcing sleeve block 32 is fixedly installed at a position near the top end of the outer wall of the pressure sensor 31, and the reinforcing sleeve block 32 is fixedly connected to the immersion sensor 30; a support block 33 is arranged on one side of the pressure sensor 31. Both the sealed housing 1 and the reinforcing sleeve block 32 are fixedly connected to the support block 33, and the support block 33 is used to support the reinforcing sleeve block 32.

[0037] The working principle of the micro high-pressure waterproof speaker of the present invention is as follows: First, when the present invention is installed and used, first, the protective shell 3 is adhesively fixed on the designated playback device, and at the same time, the power plug 12 is plugged into the power supply and communication end of the playback device, and the voice coil 14 is powered through the connection wire 11. When sound needs to be played, the voice coil 14 is powered through the connection wire 11, and a changing magnetic field appears around the voice coil 14. This changing magnetic field interacts with the constant magnetic field provided by the permanent magnet 13, resulting in the voice coil 14 being affected by the magnetic field force. This force changes with the change of the current. Therefore, the voice coil 14 will vibrate reciprocally, and the voice coil 14 will drive the vibration film 15 to perform a vibration operation. Thus, the vibration film 15 vibrates to push the surrounding air to vibrate, forming sound waves. These sound waves are transmitted through the air and are finally received by the human ear as sound, completing the sound-playing operation.

[0038] Second, when the housing of the present invention is waterproof-treated, the reinforcing sleeve block 32 is supported by the support block 33, the pressure sensor 31 is supported by the reinforcing sleeve block 32, and at the same time, the immersion sensor 30 is supported by the reinforcing sleeve block 32. When a high-pressure water body impacts the vibration film 15, the water flow will quickly flow along the outer wall of the vibration film 15 until it reaches the edge position of the connection between the sealed housing 1 and the vibration film 15, and a closed loop is formed by shifting the inner wall of the sealed housing 1 and the inner wall of the sealing ring 16. In this way, the water flow will contact the immersion sensor 30, so that the immersion sensor 30 senses that there is water flow at the edge position of the connection between the sealed housing 1 and the vibration film 15. At the same time, the pressure sensor 31 senses the pressure of the water flow impact, and immediately knows that there is a problem of water flow impact aggregation at the edge position of the connection between the sealed housing 1 and the vibration film 15.

[0039] Then, when the present invention performs lateral pressure relief and waterproofing of the casing, the microcontroller 17 immediately starts the micro motor 5. The micro motor 5 drives the linkage screw 6 to rotate. The linkage screw 6 drives the two socket blocks 7 to move away from each other under the action of the thread transmission force. In this way, one socket block 7 moves leftward and the other socket block 7 moves rightward. At the same time, the socket block 7 drives the linkage bar 8 to move leftward. The linkage bar 8 drives the frame bar 9 to move leftward. The frame bar 9 drives the lateral waterproof strip 10 to move leftward. The lateral waterproof strip 10 moves out of the inside of the sealed casing 1 from the left, and the other lateral waterproof strip 10 moves out of the inside of the sealed casing 1 from the right. In this way, the two lateral waterproof strips 10 can open the drainage ports at the lateral positions on both sides, and the drainage area on both sides of the inner wall of the sealed casing 1 is greatly increased. At the same time, it is avoided that the two lateral drainage positions are blocked, the water flow penetration pressure on both sides of the inner wall of the sealed casing 1 is greatly reduced, and at the same time, it is avoided that the high-pressure water flow penetrates into the connection between the vibration film 15 and the sealed casing 1, and the water is quickly discharged.

[0040] At the same time, when the present invention performs vertical pressure relief and waterproofing of the casing, when the socket block 7 moves leftward, the socket block 7 drives the two connecting bars 18 to move leftward synchronously. The two connecting bars 18 respectively drive the two linkage columns 19 to move leftward synchronously. The linkage column 19 drives the bottom end of the sleeve rod 20 to move leftward. The sleeve rod 20 drives the articulated column 21 to move upward. At the same time, the other articulated column 21 moves downward. The sleeve rod 20 drives the articulated push rod 22 to move upward. The articulated push rod 22 slides upward along the inner wall of the guiding sleeve block 24. At the same time, the articulated push rod 22 drives the moving bar 26 to move upward. And the moving bar 26 drives the pressing bar 27 to move upward. The pressing bar 27 drives the vertical waterproof strip 28 to move upward. The vertical waterproof strip 28 drives the rubber frame strip 29 to move upward. The rubber frame strip 29 slides upward along the inner wall of the sealed casing 1, and the other rubber frame strip 29 moves downward. At the same time, the articulated push rod 22 drives the sensing block 23 to approach the positioning distance sensor 25. The positioning distance sensor 25 senses the distance of the sensing block 23. When the distance value sensed by the positioning distance sensor 25 is the same as the distance set by the microcontroller 17, the microcontroller 17 turns off the micro motor 5. In this way, two vertical drainage ports can be opened at the top and bottom of the inner wall of the sealed casing 1. The drainage area at the top and bottom of the inner wall of the sealed casing 1 is greatly increased, and the water flow at the top and bottom of the inner wall of the sealed casing 1 can be quickly relieved and discharged, so as to avoid the high-pressure water flow from penetrating into the connection between the vibration film 15 and the sealed casing 1, and the waterproof effect of the sealed casing 1 is better.
