Description
Technical Field
[0001] The present application relates to the technical field of sound wave transducers, and in particular to a sound wave transducer with a bracket. Background Art
[0002] A sonic transducer is a device that converts electrical signals into sound waves. It is designed to generate low-frequency vibrations that can be transmitted to surfaces such as beds or furniture like sofas, turning the furniture itself into a large vibrating speaker and producing low-frequency sound effects. This technology is often used to enhance the audio experience, particularly in home theater systems, where it can provide a more immersive sound effect.
[0003] During conventional processing, the bracket and transducer housing must be separately manufactured. The transducer housing consists of an upper and lower cover, and both the upper and lower housings and the bracket must be stored separately, incurring significant storage costs. A cavity is formed between the upper and lower housings to accommodate necessary components such as T-shaped irons, magnets, and magnetic conductive sheets.
[0004] During assembly, the acoustic transducer itself must be assembled first, and then the acoustic transducer must be mounted on the bracket using multiple screws for subsequent use. This means that to obtain a fully mountable acoustic transducer with a bracket, the entire process must go through two assembly steps, making the process more cumbersome. Furthermore, the bracket is separated from the acoustic transducer at this stage, and the vibration transmission effect still needs to be improved. Utility Model Content
[0005] In order to solve the above problems, reduce the complexity of assembling the sound wave transducer before use, and at the same time ensure the vibration transmission effect, the present application provides a sound wave transducer with a bracket.
[0006] The present application provides an acoustic wave transducer with a bracket adopting the following technical solution:
[0007] A sound wave transducer with a bracket includes an upper shell and a lower shell that are covered with each other. A storage cavity is formed between the upper shell and the lower shell. A T-iron is arranged in the storage cavity. The outer periphery of the T-iron is provided with a magnet, a spring and a magnetic conductive sheet. A bracket is provided on the outer periphery of the lower shell, and a hook plate is connected between the outer periphery of the lower shell and the bracket.
[0008] By adopting the above technical solution, the bracket is integrated on the outside of the lower shell, so that the bracket and the sound wave transducer are integrated, thereby reducing the storage cost required during processing. During processing, it is only necessary to assemble the sound wave transducer, and there is no need to install the bracket separately, which simplifies the processing process, improves processing efficiency, and better meets actual needs. Moreover, after the lower shell and the bracket are integrated, the vibration transmission effect is also better.
[0009] Optionally, two spring pieces are provided, one spring piece is clamped between the lower end of the magnetic steel and the upper end of the lower part of the T iron, and the other spring piece is clamped between the upper end of the magnetic steel and the lower end of the magnetic conductive sheet.
[0010] By adopting the above technical solution, the double spring clip design is clamped to increase the vibration stroke, while reducing the vibration deviation, making it less likely to shake and ensuring the vibration stability of the product.
[0011] Optionally, a plurality of arc-shaped grooves are provided on the plate surface of the elastic piece at intervals in the circumferential direction.
[0012] By adopting the above technical solution, the formation of the arc-shaped groove increases the elastic force of the spring piece, making the spring piece both tough and elastic.
[0013] A connecting ear is provided on the outer periphery of the spring piece, a plurality of lower mounting posts are provided on the inner side of the lower shell body at intervals along the vertical direction, a plurality of first upper mounting posts are provided on the top wall of the upper shell body corresponding one to one to the lower mounting posts, and the connecting ear of the upper spring piece is clamped between the first upper mounting post and the lower mounting post; a slot for inserting a screw is provided on the upper end of the first upper mounting post, and the first upper mounting post, the spring piece and the lower mounting post are detachably connected in sequence by screws.
[0014] By adopting the above technical solution, the internal design of the lower shell is simplified, and the connection between the upper and lower shells is cleverly used to install the spring clips, saving production costs; at the same time, compared with the conventional connection ears connected by screws on the outside of the upper and lower shells, the depth of the slot in this application limits the screw from coming out, thereby better ensuring the stability of the connection between the upper and lower shells.
[0015] A plurality of second upper mounting columns are protruded from the top wall of the upper shell at intervals, and an escape opening is opened on the outer periphery of the elastic sheet, the escape opening avoids the second upper mounting columns and the first upper mounting columns, and the lower end of the second upper mounting column is connected to the connecting ear of the lower layer of the elastic sheet.
[0016] By adopting the above technical solution, the avoidance opening cooperates with the connecting ear, which not only realizes the installation of the spring piece, but also realizes the restriction of the rotation of the spring piece.
[0017] Optionally, a positioning strip is connected to the side wall of the second upper mounting column, and a positioning hole for inserting the positioning strip is formed through the plate surface of the elastic piece.
[0018] Optionally, a plurality of hook plates are arranged at intervals along the outer circumference of the lower shell, and the hook plates are S-shaped plates.
[0019] By adopting the above technical solution, instead of using a whole ring-shaped hook plate, a plurality of spaced small hook plates are used. While ensuring the stability of the connection, on the one hand, production costs are saved, and on the other hand, it is more in line with the lightweight demand. In addition, when the bracket is installed on the bed frame or sofa, when it vibrates, the upper and lower ends of the S-shaped plate are buffered by force, and the connection reliability is high, and it is not easy to break due to vibration.
[0020] Optionally, a drill hole is opened in the middle of the T iron.
[0021] By adopting the above technical solution, the drilling holes play the role of ventilation and heat dissipation, and at the same time enhance the magnetic flux density of the T iron.
[0022] Optionally, the upper end of the lower shell is provided with an embedded ring groove for the lower end of the upper shell to be inserted.
[0023] Optionally, heat dissipation holes are provided through the middle of the upper shell and the middle of the lower shell.
[0024] In summary, this application includes at least one of the following beneficial technical effects:
[0025] 1. This application integrates a bracket on the outside of the lower shell, realizing the integration of the bracket and the acoustic transducer, thereby reducing the storage costs required during processing. At the same time, during processing, only the acoustic transducer needs to be assembled, and there is no need to install the bracket separately, which simplifies the processing process, improves processing efficiency, and better meets actual needs. In addition, when the lower shell and the bracket are integrated, the vibration transmission effect is also better;
[0026] 2. This application connects the lower housing to the bracket via multiple spaced S-shaped hook plates, which not only ensures connection stability, but also saves production costs and better meets lightweight requirements.
[0027] 3. This application optimizes the internal design of the upper and lower shells, cleverly uses the connection between the upper and lower shells to install the shrapnel, and utilizes the shell's own conditions to achieve the installation of the shrapnel in the shell and limit the rotation of the shrapnel.

[0033] The following is combined with Figure 1-3 This application is described in further detail.
[0034] The embodiment of the present application discloses an acoustic wave transducer with a bracket. Figure 1 and Figure 2 The acoustic transducer with bracket 22 includes an upper housing 1 and a lower housing 2 that cover each other. A storage cavity 3 is formed between the upper and lower housings 1 and 2. A T-shaped iron 4 is mounted within the cavity 3. A magnetic steel 5, two springs 6, and a magnetic conductive sheet 7 are mounted around the outer periphery of the T-shaped iron 4. From top to bottom, the magnetic conductive sheet 7, the upper spring sheet 6, the magnetic steel 5, the lower spring sheet 6, and the lower portion of the T-shaped iron 4 are arranged. Both the upper and lower spring sheets 6 are clamped and fixed. A hole 41 is drilled in the middle of the T-shaped iron 4 to enhance heat dissipation and increase magnetic flux density.
[0035] The assembly principle and working principle of each component in the storage cavity 3 are the same as those in the existing sound wave transducer and will not be repeated here. In order to facilitate heat dissipation of internal components, heat dissipation holes 11 are opened through the middle of the upper shell 1 and the middle of the lower shell 2.
[0036] The lower housing 2 is integrally formed with a plurality of S-shaped hook plates 21 spaced along its circumference. The hook plates 21 connect the lower housing 2 to a bracket 22, which is also integrally formed with the hook plates 21, thereby integrating the lower housing 2 and the bracket 22. The bracket 22 has a plurality of mounting holes 25 formed on its surface for attaching the bracket 22 to a sofa or bed frame.
[0037] Reference Figure 3 and Figure 4 The plate surface of the spring piece 6 is circumferentially spaced apart with a plurality of arc-shaped grooves 61 , and the outer periphery of the spring piece 6 is integrally formed with a connecting ear 62 , and the plurality of connecting ears 62 are spaced apart from the axis of the spring piece 6 .
[0038] The upper end of the lower shell 2 is provided with an annular groove 23 for inserting the lower end of the upper shell 1. Multiple lower mounting posts 24 are integrally formed on the inner side of the lower shell 2 at vertical intervals. These lower mounting posts 24 are evenly arranged circumferentially about the axis of the lower shell 2. The top wall of the upper shell 1 is provided with multiple first upper mounting posts 12 at vertical intervals. These first upper mounting posts 12 correspond one-to-one with the lower mounting posts 24, and the connecting ears 62 of the upper spring clip 6 are sandwiched between the first upper mounting posts 12 and the lower mounting posts 24.
[0039] The upper end of the first upper mounting post 12 is recessed with a slot 13 for inserting a screw, so that the first upper mounting post 12, the connecting ear 62, and the lower mounting post 24 are detachably connected in sequence by means of the screw inserted into the slot 13.
[0040] In a specific embodiment, the lower mounting column 24 is connected to the side surface inside the lower shell 2, that is, a gap is left between the lower end of the lower mounting column 24 and the bottom wall of the lower shell 2, and the connecting ear 62 of the lower layer spring clip 6 is fixed to the lower end of the lower mounting column 24 by screws at the gap.
[0041] In another specific embodiment, the lower end of the lower mounting post 24 is connected to the bottom wall of the lower housing 2. A plurality of second upper mounting posts 14 are integrally formed on the top wall of the upper housing 1 at circumferential intervals. The second upper mounting posts 14 are also arranged vertically, with a gap between the bottom surface of the second upper mounting posts 14 and the bottom wall of the lower housing 2. A clearance opening 63 is defined on the outer periphery of the spring clip 6. The clearance opening 63 is large enough to allow clearance between the second upper mounting posts 14 and the first upper mounting posts 12. The connecting ears 62 of the lower spring clip 6 are fastened to the lower ends of the second upper mounting posts 14 by screws installed from bottom to top.
[0042] In addition, positioning strips 15 are integrally formed on both sides of the second upper mounting post 14 , and positioning holes 64 for inserting the positioning strips 15 are formed through the plate surface of the spring piece 6 .
[0043] Since the second specific implementation manner realizes the installation of the spring piece 6 while limiting its rotation by utilizing the internal structure of the shell itself, which is more reliable, this application takes the second specific implementation manner as an example.
[0044] The implementation principle of the sound wave transducer with a bracket in the embodiment of the present application is: the bracket 22 is integrated on the outside of the lower shell 2, so that the bracket 22 and the sound wave transducer are integrated. During processing, it is only necessary to install the magnet 5, the spring 6, the magnetic conductive sheet 7, etc. in the inner cavity in sequence, and then cover the upper shell 1 so that the lower end of the upper shell 1 is embedded with an embedded annular groove 23, and then use screws to lock the upper shell 1 and the lower shell 2, and the assembly of the sound wave transducer with the bracket 22 is completed.
[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
