Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sound waterproofing, in particular to a multi-layer sealed waterproof sounder. Background Art
[0002] Multi-layer sealed waterproof speakers are mainly used in wet or flooded environments such as outdoor activities, swimming pools, and bathrooms. They are designed to provide users with high-quality music enjoyment in these special occasions while protecting audio equipment from damage by moisture and humidity.
[0003] The traditional method of manufacturing multi-layer sealed waterproof speakers usually relies on applying waterproof glue to the threaded interface to achieve the waterproof effect. However, this method has some inherent defects. First, the coating process of the waterproof glue is easily affected by human operation, such as uneven or inadequate coating, which may cause the finished product to fail to be waterproof after assembly. Secondly, when the multi-layer sealed waterproof speaker is placed at a certain depth underwater, such as 1 meter, the water pressure will increase significantly, which may exceed the bearing capacity of the waterproof glue at the threaded interface, causing moisture to penetrate into the speaker housing through the thread gap. These problems may cause waterproof failure, affecting the normal operation of the equipment and the user experience. Utility Model Content
[0004] The utility model aims to provide a multi-layer sealed waterproof speaker to solve the problem that the multi-layer sealed waterproof speaker mentioned in the background technology is prone to waterproof failure.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A multi-layer sealed waterproof speaker comprises a shell and a hook, wherein a plurality of electronic components are arranged in the shell, and both ends of the hook are inserted into the shell for threaded cooperation with a fastener. The speaker also comprises a second seal and a connector, wherein the second seal is arranged on the inner side of the shell and sleeved on the threaded end of the hook; the connector is connected to the threaded end of the hook and squeezes the second seal to form a seal between the connector and the shell.
[0007] Furthermore, the first sealing member is elastic, and one end of the connecting member is embedded in the end surface of the first sealing member to prevent water from penetrating into the interior of the speaker from the joint between the connecting member and the first sealing member.
[0008] Furthermore, a closing piece is provided on the end surface of the shell close to the first sealing piece, and the closing piece extends toward the first sealing piece to better achieve docking and fixation of the first sealing piece and the shell during assembly.
[0009] Furthermore, the closing member is clamped on the end surface of the first sealing member to prevent water from entering the interior of the speaker through the gap between the shell and the first sealing member.
[0010] Furthermore, the threaded transition section of the hook has a closed portion, which has a seat surface in contact with the shell, and a recessed portion arranged in a manner to surround the seat surface, and a first sealing member is arranged in the recessed portion. When the seat surface is in contact with the shell, the first sealing member is in contact with the shell, so as to form an effective sealing interface in the threaded transition section of the hook.
[0011] Furthermore, the outer periphery of the first seal has a protruding portion, which protrudes further outward than the portion arranged in the recess, and the protruding portion has an inclined surface that gradually decreases in diameter toward the hook thread transition section. When the speaker is subjected to water pressure, due to the inclined surface design of the protruding portion, the first seal can better withstand the water pressure and maintain a close fit with the closing portion, thereby preventing water from flowing through the seal into the interior of the speaker.
[0012] Furthermore, a notch is provided at the inner diameter end of the first seal. Under a long-term water-stopping state, due to continuous stress, the material of the seal may creep or fatigue, resulting in shape changes and possibly causing biting, thereby reducing the sealing performance. The notch can disperse the pressure and reduce local stress concentration, thereby reducing the risk of biting and maintaining stable sealing performance.
[0013] Furthermore, the first sealing member has an engaging portion, which is engaged in the recessed portion of the sealing portion and is used to limit the movement of the first sealing member so that it maintains a relatively stable position when subjected to external force or pressure changes.
[0014] Furthermore, the first sealing member is adhered to the concave portion of the sealing portion by means of sealant, so as to ensure a close fit between the first sealing member and the sealing portion, thereby further enhancing the sealing and waterproof properties of the audio system.
[0015] The advantages of the multi-layer sealed waterproof speaker described in the utility model over the prior art are:
[0016] The multi-layer sealed waterproof speaker described in the utility model is configured so that the first seal and the connecting member tightly wrap the threaded end of the hook, thereby eliminating the gap between the threaded end of the hook and the seal. At the same time, by pressing the first seal between the shell and the connecting member, the first seal and the connecting member together form a waterproof barrier, further enhancing the waterproof effect, thereby effectively preventing external water from penetrating into the interior of the speaker along the threaded end of the hook.

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0026] Example 1: Figure 1-2 As shown, a multi-layer sealed waterproof speaker provided in this embodiment includes a shell 10 and a hook 20. The shell 10 is usually made of high-strength waterproof materials, such as polycarbonate or polyurethane. These materials not only have excellent mechanical strength and can resist collision and wear in daily use, but also have good waterproof performance and can effectively prevent water and moisture from entering the interior of the speaker.
[0027] The hook 20 can be made of stainless steel to ensure that it will not rust in a humid environment and ensure the stability of the connection with the housing 10. Both ends of the hook 20 are inserted into the housing 10 through a precise thread structure to enhance the overall sealing effect.
[0028] In order to further improve the waterproof performance, the present embodiment also sets a multi-layer waterproof structure inside the speaker. First, the second sealing member 30 is set inside the speaker and tightly sleeved on the threaded end of the hook 20. The second sealing member 30 is made of a highly sealing material, such as silicone rubber, silica gel, etc., and has good sealing and waterproof properties.
[0029] The connector 40 is connected to the threaded end of the hook 20 and squeezes the second seal to form a seal between the connector and the housing, and forms a waterproof barrier together with the second seal 30. In the sealed state, the second seal 30 is pressed by the connector 40 so that its two ends are tightly fitted with the housing 10 and the connector 40 respectively, effectively preventing moisture from penetrating along the threaded end of the hook 20.
[0030] The connector 40 can be a custom-made waterproof nut. Specifically, the waterproof nut can be made of stainless steel. Secondly, one end of the waterproof nut can be closed. This design can effectively prevent moisture from entering the interior of the speaker through the thread, thereby maintaining its normal audio output and circuit operation. At the same time, the closed design can also increase the strength and wear resistance of the thread, thereby improving the stability and durability of the connection.
[0031] In specific implementation, the waterproof nut can be customized according to the size and thread specifications of the speaker. During the processing, precise CNC machine tools or special equipment can be used to ensure the accuracy and quality of the waterproof nut.
[0032] Example 2: On the basis of the above example, in order to further improve the sealing performance, the second seal 30 can be made of an elastic material, such as silicone rubber or fluororubber, etc. These materials have excellent elasticity and can maintain good sealing performance when subjected to pressure changes. In the design of the connector 40, one end can adopt a cylindrical structure, which can be easily embedded in the end face of the second seal 30.
[0033] This design allows, after assembly, a tight and uniform contact interface to be formed between the connector 40 and the second sealing member 30. The end of the cylindrical connector 40 cooperates with the second sealing member 30 of elastic material to minimize the gaps and cracks between the two, thereby enhancing the waterproof sealing effect.
[0034] In addition, since the second sealing member 30 is made of elastic materials such as silicone rubber or fluororubber, it can produce moderate deformation when subjected to pressure changes, which helps to adapt to various stresses and vibrations that the audio equipment may encounter during use and maintain stable sealing performance.
[0035] In actual application, when the connector 40 is embedded in the end surface of the second sealing member 30, the second sealing member 30 made of elastic material will tightly wrap the cylindrical structure of the connector 40, forming an effect similar to extrusion sealing. This design can not only prevent water from penetrating in a linear direction, but also effectively prevent lateral leakage caused by pressure changes.
[0036] Of course, some auxiliary sealing elements, such as O-rings, gaskets or special coatings, may be added to the joint between the connector 40 and the second sealing member 30. These elements can form multiple layers of protection between the connector 40 and the second sealing member 30 to improve the overall waterproof level.
[0037] Example 3: Figure 3-4 As shown, on the basis of the above embodiment, similarly, in order to further improve the sealing performance, a special closing member 101 is designed on the side of the housing 10 close to the second sealing member 30. Specifically, the closing member 101 may be annular and formed by extending the housing 10. An annular groove corresponding to the closing member 101 may be provided on the second sealing member 30. The shapes and sizes of the closing member 101 and the annular groove are precisely calculated and designed so as to perfectly match the two and form a structure covering the end surface of the second sealing member 30. This design can increase the contact area between the closing member 101 and the second sealing member 30, improve the sealing effect, and reduce the possibility of moisture infiltration from the joint.
[0038] During the assembly process, the second sealing member 30 is first installed between the hook 20 and the connecting member 40, and then the annular closing member 101 of the housing 10 is aligned and pressed into the annular groove provided on the second sealing member 30. This design not only facilitates the installation and positioning of the second sealing member 30, but also, since the shapes and sizes of the closing member 101 and the groove are precisely calculated and designed, they can be perfectly matched to form a tight and uniform contact surface.
[0039] The advantage of this design is that the gaps and cracks between the annular closing member 101 and the second sealing member 30 can be effectively eliminated through the cooperation between the two, thereby enhancing the waterproof sealing effect. At the same time, since the closing member 101 is a part directly extended from the housing 10, its structural stability is stronger and it can maintain stable contact and sealing performance under pressure changes or vibrations.
[0040] It should be noted that the surfaces of the annular closure member 101 and the annular groove may be specially treated, such as coating, frosting or adding anti-skid texture, to increase friction and prevent wear. In addition, some auxiliary sealing elements, such as O-rings, gaskets or special coatings, may be added to the joint between the closure member 101 and the groove. These elements can form a multi-layer protection between the closure member 101 and the groove to improve the overall waterproof level.
[0041] Example 4: Figure 5-6As shown, on the basis of the above embodiment, in order to achieve sealing between the shell 10 and the threaded transition section of the hook 20, the threaded transition section of the hook 20 has a closing portion 201, and the closing portion 201 has a seat surface in contact with the shell 10, and a recessed portion 202 arranged in a manner of surrounding the seat surface. Specifically, the closing portion 201 can be made by a process of integrally molding with the threaded transition section of the hook 20. This process ensures a seamless connection between the closing portion 201 and the threaded transition section of the hook 20, eliminates possible gaps and leaks, and thus improves the waterproof performance.
[0042] During the manufacturing process, high-strength, corrosion-resistant materials, such as stainless steel or aluminum alloy, are first selected to make the hook 20. Then, the closing portion 201 and the thread transition section of the hook 20 are integrated and manufactured through precise mold design and molding processes such as injection molding, die casting, and forging.
[0043] The seat surface of the closing portion 201 is designed to be in contact with the housing 10, and its shape and size are precisely calculated and matched to form a stable contact and seal with the housing 10. At the same time, a recess 202 is provided on the closing portion 201 in a manner of surrounding the seat surface, and the recess 202 is used to install the first sealing member 50.
[0044] The first sealing member 50 is made of elastic material, such as silicone rubber or fluororubber, and has excellent waterproof performance. It is installed in the recess 202 and contacts with the housing 10 after assembly to form an effective waterproof barrier.
[0045] By adopting the design of the integrally formed closing portion 201, not only can the close fit and good sealing between the hook 20 and the housing 10 be ensured, but also the production efficiency can be improved and the cost can be reduced, while the stability and durability of the multi-layer sealed waterproof speaker in various wet and water-immersed environments can be ensured. In actual use, this design can effectively prevent moisture from penetrating into the interior of the speaker from the joint between the hook 20 and the housing 10, protecting the electronic components from damage.
[0046] Example 5: Figure 6As shown, on the basis of the above embodiment, in order to ensure that the first seal 50 can always maintain a seal with the shell 10 under the action of external pressure, the outer periphery of the first seal 50 has a protruding portion 501, and the protruding portion 501 protrudes further outward than the portion thereof arranged in the recess 202, and the protruding portion 501 has an inclined surface that gradually decreases in diameter toward the threaded transition section of the hook 20. Specifically, when the hook 20 is connected to the shell 10 and is subjected to pressure, the protruding portion 501 will first contact the shell 10, and distribute the pressure evenly to the entire first seal 50 through its gradually decreasing inclined surface, thereby achieving a sealing function under the action of external pressure. The design of the inclined surface also helps to guide moisture to flow outward along the inclined surface, further reducing the possibility of moisture penetration. The inclined surface is not limited to a straight line shape, but can also be a curved inclined structure. The curved inclined surface design can provide smoother pressure distribution and flow guidance, help reduce stress concentration and wear, and enhance waterproof performance.
[0047] Specifically, the curved inclined surface can be customized according to actual needs, such as using an arc shape, a parabola shape or other suitable curved shapes. This design can better adapt to the connection form and pressure changes between the hook 20 and the housing 10, ensuring that the first sealing member 50 can maintain a tight seal with the housing 10 under various use conditions.
[0048] In addition, in order to improve wear resistance and weather resistance, the extension 501 and the inclined surface may be specially treated or coated, such as adding wear-resistant materials, UV protection coatings or lubricants, etc. These measures can extend the service life of the first sealing member 50 and ensure that it can maintain good sealing performance under long-term use and external environmental influences. Example
[0049] On the basis of the above embodiment, in order to maintain the sealing performance of the first seal 50, a notch 502 is provided at the inner diameter end of the first seal 50. The notch 502 mainly serves to prevent biting. When the external pressure changes or after long-term use, the sealing material may undergo slight deformation or wear, resulting in an over-tight bite with the thread transition section of the hook 20 or other contact surfaces. The design of the notch 502 can release this part of the stress and prevent sealing failure caused by excessive biting. At the same time, the existence of the notch 502 can change the internal pressure distribution, so that the pressure acts more evenly on various parts of the first seal 50, thereby improving the overall sealing effect and durability.
[0050] Specifically, the shape, size and position of the notch 502 should be customized according to actual sealing requirements and structural design. For example, the notch 502 may be V-shaped, U-shaped, semicircular or other suitable geometric shapes.
[0051] Example 7: On the basis of the above example, in order to prevent the first seal 50 from being displaced when the pressure is too high, thereby affecting the sealing performance, the first seal 50 has a mosaic portion 503, and the mosaic portion 503 is embedded in the recess 202 of the closing portion 201. Specifically, the mosaic portion 503 cooperates with the recess 202 of the closing portion 201 to provide additional mechanical fixation and support, thereby preventing the first seal 50 from being displaced axially or radially when subjected to greater pressure.
[0052] The shape and size of the interlocking portion 503 should match the concave portion 202 of the closure portion 201 to ensure that the two can be tightly interlocked. Common designs of the interlocking portion 503 include protrusions, buckles, barbs or other suitable mechanical fixing structures. These structures can form a stable locking relationship with the concave portion 202 of the closure portion 201 when the first sealing member 50 is subjected to pressure to prevent it from moving.
[0053] In addition, the position of the fitting portion 503 is selected on the opposite side of the contact surface between the first sealing member 50 and the housing 10, which can ensure that the sealing performance is maintained without interfering with the contact and sealing between the first sealing member 50 and the housing 10. This layout can also simplify the assembly process and improve production efficiency.
[0054] Embodiment 8: Based on the above embodiment, in order to further improve the waterproofness of the sound system, the first sealing member 50 is adhered to the concave portion 202 of the closing portion 201 by means of a sealant, and the sealant may be a sealant with excellent waterproof performance, weather resistance, aging resistance and good adhesion. Common sealants include silicone sealants, polyurethane sealants or epoxy resin sealants.
[0055] First, before installing the first seal 50 into the recess 202 of the closure 201, ensure that the interior of the recess 202 is clean and dry, and free of dust, grease or other impurities that may affect the sealing effect. Secondly, evenly apply a thin and continuous layer of sealant on the inner wall of the recess 202 of the closure 201. The thickness of the sealant should be moderate, so that it can fill the gap between the recess 202 and the first seal 50, and will not overflow too much or cause assembly difficulties. Then, gently press the first seal 50 into the recess 202 of the closure 201 to ensure that it is in full contact with the sealant and evenly distributed. During the installation process, care should be taken to keep the position of the first seal 50 accurate to avoid tilting or offset. Finally, allow the sealant to cure under specified conditions (such as leaving it at room temperature for a certain period of time or heating to accelerate curing. After it is completely cured, check whether a firm and uniform sealing interface is formed between the first seal 50 and the closure 201, and confirm that there is no water seepage or air leakage.
[0056] When the device is in use, when the speaker is subjected to external water pressure, the gradually tapering slope of the extended surface of the first seal 50 can effectively distribute the pressure evenly to the entire first seal 50 under the action of the water pressure, thereby preventing sealing failure caused by excessive local pressure.
[0057] At the same time, when water pressure is applied to the protruding portion 501, the inclined surface can guide the water flow to disperse outward along its shape instead of directly impacting the sealing part, thereby reducing the risk of moisture penetration.
[0058] In addition, the notch 502 formed at the inner diameter end of the first seal 50 also plays a key role. It can prevent the first seal 50 from excessive deformation or biting under water pressure, thereby maintaining the stability of the sealing performance. The presence of the interlocking portion 503 provides additional mechanical fixing and support, preventing the first seal 50 from axial or radial displacement when subjected to high water pressure, thereby ensuring close contact and sealing effect between the first seal 50 and the housing 10.
[0059] Finally, by using sealant to adhere between the first sealing member 50 and the sealing portion 201, the sealing performance between the two is enhanced, forming a second line of defense to prevent moisture from penetrating into the interior of the speaker from their joints.
[0060] The connector 40 and the second seal 30 form a third line of defense inside the speaker. The connector 40 uses a customized nut to ensure a tight fit with the threaded end of the hook 20. At the same time, the second seal 30 is made of a highly elastic and wear-resistant rubber material and can fit tightly on the connector 40 to form an effective sealing structure.
[0061] These three lines of defense work together to enable the multi-layer sealed waterproof speaker to resist the invasion of various water pressures and maintain the normal operation and sound quality of its internal circuits and components. This waterproof design can not only meet the needs of users in various environments, but also improve the reliability and durability of the multi-layer sealed waterproof speaker.

The same expression appearing in multiple places in the specification does not necessarily refer to the same embodiment. Further, when a structure is described in conjunction with any embodiment, it is claimed that the structure is implemented in conjunction with other embodiments within the scope of the utility model.
