Description

Technical Field

[0001] This utility model relates to the field of acoustic-electric conversion technology, and in particular to a waterproof loudspeaker with a bent diaphragm. Background Technology

[0002] With the rapid popularization of smart wearable products, waterproof speakers, as key acoustic components, are widely used in devices such as smartwatches and fitness trackers. However, in actual use, especially after repeated water immersion tests, the problem of delamination between the diaphragm and the support / frame has gradually emerged, becoming a significant factor affecting product reliability. This problem mainly stems from insufficient connection strength between the diaphragm and the support, and between the diaphragm and the frame, the root cause of which lies in the limitations of the existing structural design.

[0003] From a structural design perspective, the bracket and frame have mutually facing clamping surfaces, and the diaphragm has a membrane clamping portion located between these surfaces. Existing waterproof loudspeakers use planar clamping surfaces for both, with the corresponding membrane clamping portion also being flat. This planar contact design means the connection strength depends entirely on the width of the bracket and frame. In practical applications, a width of 0.5mm has become the industry standard. This size selection is primarily based on two considerations: firstly, wearable products impose strict limitations on the structural space of loudspeakers, and excessively wide brackets and frames would encroach on the installation space of other components; secondly, from an acoustic performance perspective, maintaining an appropriate width helps maintain the loudspeaker's sound quality. However, this design has revealed significant drawbacks in long-term use—the excessively narrow contact surfaces result in a severe lack of bonding area between the diaphragm and the bracket, as well as between the diaphragm and the frame. This makes it difficult for the connection strength between the diaphragm and the bracket / frame to meet waterproof requirements, easily leading to the diaphragm detaching from the frame and bracket. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof speaker with a bent diaphragm, which can effectively solve the problem of the diaphragm easily falling off the frame and support.

[0005] To achieve the above objectives, this utility model provides the following solution: A bent diaphragm waterproof loudspeaker includes a frame, a cover on one end of the frame, and a vibration system and a magnetic circuit system fixed to the frame. The vibration system includes a support, a diaphragm, and a voice coil assembly. The support is annular and located within the cover. The support and the frame each have a support clamping surface and a frame clamping surface, which face each other, and at least one of them is bent. The diaphragm includes a diaphragm vibrating portion and a diaphragm clamping portion located between the frame clamping surface and the support clamping surface. The diaphragm clamping portion is bonded to the frame clamping surface and to the support clamping surface. The diaphragm clamping portion is bent, and its length along the width direction of the support is greater than the width of the support and the width of the frame.

[0006] In one embodiment of this application, the width of the membrane clamping portion is equal to the width of the support.

[0007] In one embodiment of this application, the membrane clamping portion is Z-shaped and includes a first clamping segment, a second clamping segment, and a third clamping segment connected in sequence; the first clamping segment is connected to the membrane vibration portion; both the first clamping segment and the third clamping segment extend along the width direction of the support, and the third clamping segment is located on the side of the first clamping segment away from the basin frame.

[0008] In one embodiment of this application, the basin holder clamping surface is a plane, and the support clamping surface is Z-shaped similar to the membrane clamping part; the second clamping section, the third clamping section, and the basin holder clamping surface form a glue storage tank, and the glue storage tank is filled with adhesive material.

[0009] In one embodiment of this application, the diaphragm further includes an adhesive reinforcement portion, which includes a first adhesive reinforcement section surrounding the bracket and a second adhesive reinforcement section located on the side of the bracket away from the basin frame. The first adhesive reinforcement section is bonded to the bracket and the second adhesive reinforcement section is bonded to the bracket by an adhesive substance.

[0010] In one embodiment of this application, the width of the membrane clamping portion is smaller than the width of the support.

[0011] In one embodiment of this application, the membrane clamping portion is L-shaped and includes a first clamping section and a second clamping section connected to each other. The first clamping section is connected to the membrane vibration section and extends along the width direction of the support; the second clamping section extends in the direction from the basin frame to the support.

[0012] In one embodiment of this application, the basin stand clamping surface is a plane; the bracket clamping surface is a Z-shaped bent surface, having a first flat portion that is attached to the first clamping segment, a second flat portion that is attached to the second clamping segment, and a third flat portion located on the side of the first flat portion away from the basin stand; the basin stand clamping surface, the third flat portion, and the third clamping segment form an adhesive reservoir filled with adhesive material.

[0013] In one embodiment of this application, a raised texture structure is pressed onto the surface of the membrane clamping portion.

[0014] In one embodiment of this application, the cover plate of the sealing cap presses against the vibration system.

[0015] The bent diaphragm waterproof speaker of this utility model has the following advantages compared with the prior art: This invention, by configuring the membrane vibrating part clamped between the support and the basin frame as a bent shape, and by making the length of the bent membrane vibrating part along the width direction of the support greater than the width of the support and the width of the basin frame, and by configuring at least one of the support clamping surface and the basin frame clamping surface as a bent surface, can increase the area of ​​the bonding surface between the membrane clamping part and the support, and between the membrane clamping part and the basin frame without changing the width of the support and the basin frame. This enhances the adhesion between the membrane clamping part and the support, and between the membrane clamping part and the basin frame. Moreover, the bent shape of the membrane clamping part can form a continuous adhesive layer seal, significantly reducing the risk of water penetration. On the other hand, it also changes the stress distribution path when the diaphragm is deflected, optimizes the stress state of the adhesive layer, and further helps to improve the connection strength between the diaphragm and the support and basin frame, making it less likely for the diaphragm to detach from the support and basin frame.

[0018] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0019] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0020] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0021] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the related listed items.

[0022] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.

[0023] Example 1: Please see Figures 1 to 5 This is a bent diaphragm waterproof speaker as shown in Embodiment 1 of this utility model, such as... Figure 3As shown, the bent diaphragm waterproof loudspeaker includes a hollow frame 10, a cover 20 on one end of the frame 10, and a vibration system 30 and a magnetic circuit system fixed on the frame 10; the magnetic circuit system is used to drive the vibration system 30 to vibrate and produce sound.

[0024] Depend on Figure 3 It is understood that the vibration system 30 includes a support 31, a diaphragm 32, and a voice coil assembly for driving the diaphragm 32 to vibrate and produce sound. The support 31 is ring-shaped, located inside the cover 20, and on one side of the frame 10. The support 31 and the frame 10 form a vibration cavity. Figure 4 As shown, the support 31 and the basin stand 10 respectively have a support clamping surface 311 and a basin stand clamping surface 11, the basin stand clamping surface 11 and the support clamping surface 311 are arranged facing each other, and at least one of them is arranged as a bent surface; the diaphragm 32 includes a membrane vibration part 321 located in the vibration cavity and a membrane clamping part 322 located between the basin stand clamping surface 11 and the support clamping surface 311; the membrane clamping part 322 is connected to the basin stand clamping surface 11 and to the support clamping surface 311 by an adhesive material, the membrane clamping part 322 is arranged in a bent shape, and the length of the membrane clamping part 322 along the width direction of the support 31 is greater than the sum of the widths of the basin stand 10 and the support 31.

[0025] This invention increases the bonding surface between the membrane clamping part 322 and the support 31 and the basin frame 10 by making the membrane vibrating part 321, which is sandwiched between the support 31 and the basin frame 10, and by making at least one of the support clamping surface 311 and the basin frame clamping surface 11 a bent surface, without changing the width of the support 31 and the basin frame 10. The increased surface area enhances the adhesion between the membrane clamping part 322 and the support 31, as well as the adhesion between the membrane clamping part 322 and the basin frame 10. Furthermore, the bent shape of the membrane clamping part 322 not only forms a continuous adhesive layer seal, significantly reducing the risk of water penetration, but also alters the stress distribution path of the diaphragm 32 when subjected to external force, optimizing the stress state of the adhesive layer. This further helps to improve the fixation strength between the diaphragm 32 and the support 31 and the basin frame 10, making it less likely for the diaphragm 32 to detach from the support 31 and the basin frame 10.

[0026] It should be noted that, in order to clearly demonstrate the geometric features and mating relationship of the membrane clamping part 322, the frame clamping surface 11, and the support clamping surface, Figure 3 , Figure 4 The adhesive layer structure between the membrane clamping part 322 and the basin frame 10, and between the membrane clamping part 322 and the support 31 is omitted from the text.

[0027] The adhesive material between the membrane clamping part 322 and the basin frame 10, and between the membrane clamping part 322 and the support 31, can be glue, hot melt adhesive, UV curing adhesive, epoxy resin glue, etc. In this embodiment, glue is selected as the adhesive material between the membrane clamping part 322 and the basin frame 10, and between the membrane clamping part 322 and the support 31.

[0028] To maximize the connection force between the membrane clamping portion 322 and the support 31, as well as the connection between the membrane clamping portion 322 and the basin frame 10, in this embodiment, the width of the membrane clamping portion 322 is equal to the width of the support 31. Furthermore, as... Figure 3 As shown, the membrane clamping portion 322 is Z-shaped and includes a first clamping section 3221, a second clamping section 3222, and a third clamping section 3223 connected to each other. The first clamping section 3221 is connected to the membrane vibration section 321. Both the first clamping section 3221 and the third clamping section 3223 extend along the width direction of the support 31, and the third clamping section 3223 is located on the side of the first clamping section 3221 away from the basin frame 10. The Z-shaped arrangement of the membrane clamping portion 322 provides a better stress distribution path that prevents the membrane clamping portion 322 from detaching from the basin frame and the support 31. In this embodiment, the third clamping section 3223 is preferably perpendicularly connected to both the first clamping section 3221 and the second clamping section 3222.

[0029] In this embodiment, the basin holder clamping surface 11 is flat, and the support clamping surface 311 is Z-shaped, similar to the membrane clamping part 322. The second clamping section 3222, the third clamping section 3223, and the basin holder clamping surface 11 form a glue storage tank 100. An adhesive substance with bonding function is placed in the glue storage tank 100. The glue storage tank 100 has an opening on the side facing the side wall of the cap 20 so that the operator can observe the adhesive substance in the glue storage tank 100 through the opening. The adhesive substance can be glue, hot melt glue, UV curing adhesive, epoxy resin glue, etc. In this embodiment, glue is selected as the adhesive substance in the glue storage tank 100. The adhesive storage tank 100 increases the bonding area of ​​the membrane clamping part 322 near the basin frame 10, thereby increasing the adhesion between the membrane clamping part 322 and the basin frame 10. Simultaneously, operators can directly observe through the opening of the adhesive storage tank 100 whether the adhesive material is evenly distributed and free of air bubbles or impurities, preventing adhesion failure due to internal defects after the vibration system 30 is fastened to the basin frame 10. Furthermore, after the cap 20 is placed on the basin frame 10, the adhesive material in the adhesive storage tank 100 connects to the side wall of the cap 20, allowing the cured adhesive material in the adhesive storage tank 100 to form a water-proof barrier. The water inlet paths of the sound device product are the gap between the bracket 31 and the cover 20 and the gap between the bracket 31 and the membrane clamping part 322. For these two leakage paths, the only protection is the adhesive layer between the bracket 31 and the cover 20 and the membrane clamping part 322. There is a certain probability that this adhesive layer will fail. When the adhesive layer fails in these two paths, the adhesive material in the glue tank 100 can provide secondary protection to prevent external water from entering between the bracket 31 and the cover 20 and between the bracket 31 and the membrane clamping part 322.

[0030] The existing speaker's bracket clamping surface 311 and frame clamping surface 11 are both flat. Since the width of the bracket 31 and the frame 10 is 0.5mm, the length of the surface of the diaphragm clamping part 322 of the existing speaker diaphragm 32 that is attached to the bracket 31 and the surface of the diaphragm clamping part 322 that is attached to the frame 10 along the width direction of the bracket 31 is also 0.5mm. Figure 5 This is a cross-sectional view of the membrane clamping part 322 in this embodiment. Figure 5It can be seen that in this embodiment, the lengths of the surfaces where the membrane clamping part 322 is bonded to the support 31 and the surfaces where the membrane clamping part 322 is bonded to the basin frame 10 are equal along the width direction of the support 31, and are both L1+L2+L3. In this embodiment, the widths of both the support 31 and the basin frame 10 are selected as 0.5mm, L1 is 0.3mm, L3 is 0.2mm, and L2 is 0.25-0.3mm. Therefore, the length of the surface where the membrane clamping part 322 is bonded to the support 31 along the width direction of the support 31 is 0.3+0.2+(0.25-0.3)=(0.75-0.8)mm. Compared with the existing 0.5mm, the area of ​​the surfaces where the membrane clamping part 322 is bonded to the support 31 and the basin frame 10 is increased by 50%-60%. It should be noted that the data for L1, L2, and L3 in this application are not limited to the data mentioned above. In other feasible embodiments, the data for L1, L2, and L3 may be selected from other data according to the manufacturing requirements.

[0031] Alternatively, in other feasible embodiments, the adhesive reservoir 100 may be omitted, and the basin holder clamping surface 11 may be directly configured as a Z-shape similar to the membrane clamping portion 322. In other feasible embodiments, a raised texture structure may be pressed onto the surface of the membrane clamping portion 322 to increase the contact area between the membrane clamping portion 322 and the adhesive, thereby further increasing the connection force between the membrane clamping portion 322 and the support 31.

[0032] In this embodiment, by Figure 2 and Figure 3 It is known that the membrane vibration unit 321 includes a flat diaphragm 3211, a folded ring 323 connecting the flat diaphragm 3211 and the membrane clamping unit 322, and a dome 3212 fixed on the flat diaphragm 3211. The dome 3212 is located on the side of the flat diaphragm 3211 away from the support 31.

[0033] In this embodiment, the voice coil assembly is located on the side of the dome 3212 away from the support 31. The voice coil assembly includes a voice coil 331 and an FPC board 332. Both the voice coil 331 and the FPC board 332 are mounted inside the frame 10, and the FPC board 332 is electrically connected to the voice coil 331. In this embodiment, the FPC board 332 is ring-shaped and surrounds the voice coil 331.

[0034] In this embodiment, the cover plate of the cap 20 is spaced apart from the vibration system 30. In other feasible embodiments, the cover plate of the cap 20 may be positioned to press against the vibration system 30. This arrangement can counteract the loosening of the connection caused by creep or aging that may occur due to long-term use of the adhesive, ensuring the stability of the connection between the diaphragm 32 and the support 31 and the frame 10.

[0035] In this embodiment, the magnetic circuit system is located inside the cavity of the frame 10 and on the side of the voice coil assembly away from the support 31. The magnetic circuit system includes a magnetic cover 41, a magnet assembly 42, and a pole piece 43 arranged sequentially along the direction from the frame 10 to the support 31. The magnetic cover 41 is fixed to the frame 10, the magnet assembly 42 is fixed to the magnetic cover 41, and the pole piece 43 is fixed to the magnet assembly 42 and located inside the voice coil 331.

[0036] Example 2: Please see Figure 6 and Figure 7 This is a second embodiment of the present invention, showing a bent diaphragm waterproof speaker. The difference between this embodiment and the first embodiment is that: Depend on Figure 7 It is understood that the diaphragm 32 also includes an adhesive reinforcement portion 324. The adhesive reinforcement portion 324 includes a first adhesive reinforcement section 3241 surrounding the support 31 and a second adhesive reinforcement section 3242 located on the side of the support 31 away from the frame 10. The first adhesive reinforcement section 3241 and the support 31, as well as the second adhesive reinforcement section 3242 and the support 31, are bonded together by an adhesive material, such as glue, hot melt adhesive, UV-cured adhesive, epoxy resin, etc. In this embodiment, glue is selected as the adhesive material. The setting of the adhesive reinforcement portion 324 can, on the one hand, further increase the bonding area between the diaphragm 32 and the support 31, thereby achieving the beneficial effect of further increasing the bonding strength between the diaphragm 32 and the support 31. On the other hand, it can disperse the vibration stress of the diaphragm 32 and reduce the risk of deformation at the connection between the diaphragm 32 and the support 31.

[0037] It should be noted that, in order to clearly demonstrate the geometric features and mating relationship of the membrane clamping part 322, the frame clamping surface 11, and the support clamping surface 311, Figure 6 , Figure 7 The adhesive layer structure between the membrane clamping part 322 and the basin frame 10, and between the membrane clamping part 322 and the support 31 is omitted from the text.

[0038] Example 3: Please see Figures 8 to 10 The third embodiment of this utility model is a waterproof speaker with a bent diaphragm. The difference between this embodiment and the first embodiment is that: like Figure 9As shown, the membrane clamping part 322 is L-shaped and includes a first clamping section 3221 and a second clamping section 3222 connected to each other. The first clamping section 3221 is connected to the membrane vibration part 321 and extends along the width direction of the support 31. The second clamping section 3222 extends toward the basin frame 10 to the support 31. The Z-shaped support clamping surface 311 has a first flat part 3111 that is attached to the first clamping section 3221, a second flat part 3112 that is attached to the second clamping section 3222, and a third flat part 3113 located on the side of the first flat part 3111 away from the basin frame 10. The basin stand clamping surface 11, the third flat portion 3113, and the second clamping section 3222 form a glue reservoir 100 filled with adhesive material. In this embodiment, the function of the glue reservoir 100 is the same as that shown in Embodiment 1, and will not be described in detail here. After the cover 20 is placed on the basin stand 10, the adhesive material in the glue reservoir 100 is bonded to the side wall of the cover 20. In other embodiments, the glue reservoir 100 can be removed, and the basin stand clamping surface 11 can be replaced by a Z-shaped bent surface instead of a flat surface.

[0039] Depend on Figure 10 It can be seen that in this embodiment, the length of the surface where the diaphragm 32 is bonded to the support 31 along the width direction of the support 31 is equal to L1 + L2. In this embodiment, the width of both the support 31 and the basin frame 10 is selected as 0.5mm, L1 is selected as 0.3mm, and L2 is selected as 0.25-0.3mm. Therefore, the length of the surface where the membrane clamping part 322 is bonded to the support 31 and the surface where the membrane clamping part 322 is bonded to the basin frame 10 along the width direction of the support 31 is 0.3 + (0.25 - 0.3) = 0.55mm - 0.6mm. Compared with the existing 0.5mm, the area of ​​the surface where the membrane clamping part 322 is bonded to the support 31 and the surface where the membrane clamping part 322 is bonded to the basin frame 10 is increased by 10%-20%. It should be noted that the data of L1 and L2 in this application are not limited to the data mentioned above. In other feasible embodiments, the data of L1 and L2 can be selected according to the manufacturing requirements.

[0040] It should be noted that, in order to clearly demonstrate the geometric features and mating relationship of the membrane clamping part 322, the frame clamping surface 11, and the support clamping surface 311, Figure 8 , Figure 9 The adhesive layer structure between the membrane clamping part 322 and the basin frame 10, and between the membrane clamping part 322 and the support 31 is omitted from the text.

[0041] In summary, the bent diaphragm waterproof loudspeaker provided in this embodiment of the present invention has at least the following characteristics: 1. The membrane vibrating part 321, which is clamped between the support 31 and the basin frame 10, is configured to be bent. The length of the bent membrane vibrating part 321 along the width direction of the support 31 is greater than the width of the support 31 and the width of the basin frame 10. At the same time, at least one of the support clamping surface 311 and the basin frame clamping surface 11 is configured as a bent surface. This increases the bonding surface between the membrane clamping part 322 and the support 31, and the bonding surface between the membrane clamping part 322 and the basin frame 10, without changing the width of the support 31 and the width of the basin frame 10. The increased surface area enhances the adhesion between the membrane clamping part 322 and the support 31, as well as the adhesion between the membrane clamping part 322 and the basin frame 10. Furthermore, the bent shape of the membrane clamping part 322 not only forms a continuous adhesive layer seal, significantly reducing the risk of water penetration, but also alters the stress distribution path of the diaphragm 32 when subjected to external force, optimizing the stress state of the adhesive layer. This further helps to improve the fixing strength between the diaphragm 32 and the support 31 and the basin frame 10, making it less likely for the diaphragm 32 to detach from the support 31 and the basin frame 10.

[0042] 2. Without changing the width of the support 31, the membrane clamping section is bent into a Z-shape, and the support clamping surface 311 is set as a Z-shaped bending surface. This can increase the bonding area between the diaphragm 32 and the support 31 by at least 50%. Moreover, by setting both the membrane clamping part 322 and the support clamping surface 311 as Z-shaped, a glue storage tank 100 can be formed between the membrane clamping part 322 and the basin frame clamping surface 11. After the glue storage tank 100 is filled with adhesive material, the bonding area on the side of the membrane clamping part 322 facing the basin frame 10 can be increased. At the same time, the testability of the adhesive material in the glue storage tank 100 can be ensured. In addition, it can provide double protection for the leakage path between the support 31 and the cap 20, and between the support 31 and the diaphragm.

[0043] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
