Abstract
Description
Technical Field
[0001] This utility model relates to a speaker bracket module and a speaker. Background Technology
[0002] The padding is one of the components of the speaker, and it is usually fixed to the speaker bracket. When the speaker is installed on the car body (such as the door panel), the padding is tightly located between the bracket and the car body, playing the roles of buffering, shock absorption, sealing and dust prevention. At present, the padding is mainly installed by the following three methods: (1) Cut out a ring-shaped padding from a whole sheet of double-sided adhesive, and then attach it to the ring mounting surface of the bracket with double-sided adhesive. However, this method will generate a lot of cutting waste, and the material of the middle part of the ring cannot be used, which will increase the cost of the padding and waste a lot of materials. (2) Apply glue to the ring mounting surface of the bracket and attach the padding or apply self-foaming padding. This method requires the investment of glue application equipment, and the gun head cannot contact the bracket in areas with obstruction, so automatic glue application cannot be achieved or the automatic glue application process is more complicated. If manual glue application is used, firstly, the labor cost is high, the glue amount cannot be controlled, which may result in an unsightly overflow, or too little glue to adhere firmly and cause peeling. (3) Using strips of cotton padding with double-sided adhesive, a closed loop of cotton padding is formed to fit the shape of the mounting surface. However, if the mounting surface is not circular but irregular with corners, stress concentration can easily occur at the corners, causing the cotton padding to fall off after a period of time. Furthermore, the overlap at the corners affects the effectiveness of the cotton padding and is also unsightly. Although some improvement solutions involve designing positioning structures on the speaker bracket to make it easier to attach the cotton padding, these solutions do not consider the shape of the sealing material itself or its cost.
[0003] The information disclosed in the background section is only intended to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0004] The purpose of this utility model is to provide a speaker bracket module and speaker, which solves the problem of stress concentration at the corner of the bracket by the padding strip, so that the padding strip is firmly attached to the speaker bracket, effectively achieving waterproof and shock absorption effects, while also being low in cost and having a neat and beautiful appearance.
[0005] The present invention adopts the following technical solution:
[0006] A speaker bracket module includes a bracket and padding. The bracket is hollow and has an open mounting end with a mounting plane facing the component to be mounted. The padding is formed by padding strips joined end-to-end and attached to the mounting plane. The mounting plane has a main section and a protruding section, the inner diameter of the protruding section being larger than the inner diameter of the main section, and the protruding section having a corner. The padding strips have notches, and after the padding strips are attached to the mounting plane, the notches are located at the corners, and the padding strip material on both sides of the notches is squeezed towards the notches so that the width of the notches is smaller than their initial width.
[0007] In a preferred embodiment, the initial shape of the notch is triangular; after the padding strip is attached to the mounting surface, the shape of the notch becomes a slit.
[0008] In a more preferred embodiment, the initial width of the notch is less than the height of the notch, and the height of the notch is less than or equal to half the width of the padding strip. Here, the initial width of the notch refers to the maximum dimension of the padding strip along its length before the notch is compressed, and the height of the notch refers to the maximum dimension of the notch along the width of the padding strip.
[0009] In a more preferred embodiment, after the padding strip is attached to the mounting surface, the inner walls on both sides of the notch come into contact with each other.
[0010] In a preferred embodiment, the notch includes a first notch and a second notch, the first notch and the second notch being spaced apart, the first notch facing outward from the mounting end and the second notch facing inward from the mounting end.
[0011] In a preferred embodiment, the protruding section is lower than the main body section, and a water guiding cavity is provided between the protruding sections. The inner wall of the water guiding cavity has a water guiding surface for guiding water flow. The water guiding surface is inclined to guide water entering the bracket into the water guiding cavity.
[0012] In a preferred embodiment, the protruding section is provided with a first buckle; the main body section is provided with a second buckle; the bracket further includes a plurality of fastening parts, the plurality of fastening parts surrounding the outside of the mounting end, and the fastening parts are provided with fasteners or mounting holes for fasteners to pass through.
[0013] In a preferred embodiment, the mounting end further has a limiting flange disposed on the inner edge of the mounting plane to restrict the padding strip to the outside of the limiting flange.
[0014] This utility model also adopts the following technical solution:

[0016] In a preferred embodiment, a water-guiding cavity is formed between the protruding segments, the diaphragm has a back surface facing the mounting end, a sound cavity is formed between the back surface and the bracket, and the water-guiding cavity is located below the sound cavity.
[0017] The present invention adopts the above solution and has the following advantages compared with the prior art:
[0018] The speaker and its bracket module of this utility model adopt a specially designed strip of padding cotton to be spliced into a ring-shaped padding cotton. The padding cotton strip has small notches cut into the corner areas of the bracket according to the shape of the bracket. When it is attached to the mounting surface of the bracket, the small notches in the corner areas of the padding cotton will not cause overflow accumulation. The padding cotton will be attached more evenly, reducing the stress concentration caused by directly attaching long strips of padding cotton. The attachment will be more firm and the appearance will be cleaner. When the speaker is installed with the car body (door sheet metal parts), it can achieve excellent sealing, waterproofing and shock absorption effects. Attached Figure Description

[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0033] In this article, "inner" and "outer" are defined with reference to the vibration axis of the loudspeaker. The position closer to the vibration axis of the loudspeaker is the inner position, and the opposite position is the outer position.
[0034] Figures 1 to 6 The diagrams are drawn to scale. To keep the instructions concise, the proportions of each component are not listed individually. However, the proportions and positions of each component should be considered part of the contents of this instruction manual.
[0035] This embodiment provides a speaker and its bracket module, the speaker being a vehicle-mounted speaker. (See reference...) Figures 1 to 6 As shown, the speaker 1's support module includes a support 11 and a padding 12. The support 11 can be an injection-molded part made of plastic in one piece; the padding 12 is a flexible material that can absorb vibration and provide dustproof sealing. Figure 4As shown, the bracket 11 is hollow and has an open mounting end 110 and a diaphragm fixing end 140, which are two opposite ends. The outer edge of the diaphragm 13 of the speaker 1 is suspended and fixed to the diaphragm fixing end 140, and the diaphragm 13 covers the diaphragm fixing end 140. Specifically, in the woofer of this embodiment, the diaphragm 13 is housed in the bracket 11, and the voice coil (not shown) is also housed in the bracket 11. The bracket 11 also has a magnetic circuit mounting part 150, which is fixed to the inner wall of the bracket 11 by a plurality of connecting strips 151, and the magnetic circuit 14 of the speaker 1 is fixed to the magnetic circuit mounting part 150. The mounting end 110 surrounds the periphery of the magnetic circuit mounting part 150 and is fixed to the component to be mounted, such as the cabinet of a speaker box or the body of a vehicle. For the woofer of this embodiment, the mounting end 110 can be fixed to the sheet metal of a door panel.
[0036] The mounting end 110 has a mounting surface 111 facing the component to be mounted, and this mounting surface 111 is generally annular. The padding 12 is formed by padding strips 120, which are attached to the mounting surface 111 end-to-end. The mounting surface 111 has a main section 1111 and a protruding section 1112. The main section 1111 is generally arc-shaped or composed of multiple arc-shaped parts. The inner diameter of the protruding section 1112 is larger than the inner diameter of the main section 1111, thus protruding outward relative to the main section 1111. There can be one or more protruding sections 1112; specifically, in the case of the vehicle subwoofer shown in the attached figure, the protruding section 1112 is located at the bottom of the bracket 11, i.e., below the main section 1111, to facilitate drainage of accumulated water and the installation of clips, etc.
[0037] like Figure 2 As shown, the protruding segment 1112 has corner portions 1113, and the number of corner portions 1113 can be one or more. A corner portion 1113 refers to a location where the inner diameter of the protruding segment 1112 changes abruptly; in the specific example shown in the attached figure, the protruding segment 1112 has four corner portions 1113, two of which are located at or near the junction of the protruding segment 1112 and the main body segment 1111. Figure 3 As shown, the padding strip 120 has a notch 121, and each corner 1113 corresponds to at least one notch 121. Combined with... Figure 1 As shown, after the padding strip 120 is attached to the mounting surface 111, the notch 121 is located at the corner 1113, and the padding strip 120 material on both sides of the notch 121 is squeezed toward the notch 121 so that the width of the notch 121 is less than its initial width.
[0038] Specifically, in this embodiment, the initial shape of the notch 121 is triangular; after the padding strip 120 is attached to the mounting surface 111, the shape of the notch 121 becomes a slit. The initial width w of the notch 121 is less than the height h of the notch 121, and the height h of the notch 121 is less than or equal to half the width of the padding strip 120. After the padding strip 120 is attached to the mounting surface 111, the width of the compressed notch 121 can be 0, much smaller than its initial width w. That is to say, after the padding strip 120 is attached to the mounting surface 111, the inner walls of the two sides of the notch 121 are in contact with each other.
[0039] Further, the notch 121 includes a first notch 121a and a second notch 121b, which are spaced apart. The first notch 121a faces outward from the mounting end 110 (away from the magnetic circuit 14), and the second notch 121b faces inward from the mounting end 110 (towards the magnetic circuit 14). Along Figure 1 In the clockwise direction, for the corner 1113 where the inner diameter suddenly increases, a first notch 121a corresponding to the corner 1113 is opened on the padding strip 120; for the corner 1113 where the inner diameter suddenly decreases or the change tends to be gradual, a second notch 121b corresponding to the corner 1113 is opened on the padding strip 120.
[0040] Specifically, in this embodiment, the protruding section 1112 is lower than the main body section 1111, and a water guiding cavity 114 is formed between the protruding sections 1112. The inner wall of the water guiding cavity 114 has a water guiding surface 115 for guiding water flow. The water guiding surface 115 is inclined to guide water entering the bracket 11 into the water guiding cavity 114. The diaphragm 13 has a back surface facing the mounting end 110, and a sound cavity 113 is formed between the back surface and the bracket 11. The water guiding cavity 114 is located below the sound cavity 113. Figure 6 As shown, when the bracket 11 module is installed on the door panel, the water guiding cavity 114 is located at the lowest point. Water entering the speaker cavity 113 is guided to the water guiding cavity 114 under the action of gravity and the inclined water guiding surface 115, and can be discharged from the water guiding cavity 114. This avoids water from contacting the diaphragm 13 and other components for a long time, thereby avoiding the speaker from failing to work or making abnormal noises due to the diaphragm 13 being soaked in water and damaged.
[0041] Furthermore, the protruding section 1112 is provided with a first buckle 131, and the upper part of the main body section 1111 is also provided with a second buckle 132. The second buckle 132 and the first buckle 131 are arranged vertically at intervals, and can be pre-fixed to the door panel by the first buckle 131 and the second buckle 132 during installation. The bracket 11 also includes multiple fastening parts 133, which surround the outside of the mounting end 110. The fastening parts 133 are provided with fasteners or mounting holes for fasteners to pass through. After being pre-fixed by the first buckle 131 and the second buckle 132, the multiple fastening parts 133 can be locked to the door panel by screws or other fasteners to achieve a stable installation of the speaker.
[0042] Furthermore, such as Figure 5 As shown, the mounting end 110 also has a limiting flange 112, which is disposed on the inner edge of the mounting plane 111 to restrict the padding strip 120 to the outside of the limiting flange 112. An annular groove is formed between the limiting flange 112 and the mounting plane 111, and the padding strip 120 is restricted within the annular groove. The padding strip 120 can protrude relative to the limiting flange 112, and when installed, the padding strip 120 fits tightly between the door panel and the bracket 11.
[0043] A small triangular notch 121, approximately half the width of the padding strip 120, is cut into the corner area of the bracket 11 according to the shape of the bracket 11. When the padding strip 12 is fitted to the mounting surface 111 of the bracket 11, the small notch 121 prevents excess material buildup at the corner, allowing for a smoother fit and reducing stress concentration caused by directly pasting the long strip. This results in a more secure fit and a cleaner appearance. The speaker also achieves sealing, waterproofing, and shock absorption when installed on the vehicle's sheet metal. In this embodiment, the speaker manufacturing and assembly process is simpler, saving material and labor costs, resulting in lower manufacturing costs. It is firmly fixed, effectively providing waterproofing and shock absorption; stress prevents the padding strip 12 from detaching, and the appearance is neat and aesthetically pleasing.
