Description

Technical Field

[0001] This utility model relates to the technical field of speaker grille installation structure, specifically to a magnetic speaker grille installation structure. Background Technology

[0002] In traditional magnetic speaker grille installation structures, a simple array of alternating N and S poles of magnets or a single-sided magnet adsorption scheme is typically used to achieve quick assembly and disassembly of the grille to the device. While this design is simple in structure, it often faces problems of insufficient or uneven magnetic force in practical applications, especially in environments requiring frequent disassembly or vibration, where the grille is prone to loosening or even falling off due to insufficient adsorption force. Furthermore, the traditional magnet arrangement causes the magnetic field to diffuse in all directions, reducing the magnetic flux density of the effective adsorption surface and potentially causing unnecessary electromagnetic interference to surrounding electronic devices (such as smartphones and smartwatches), affecting the user experience.

[0003] However, existing magnetic horn mesh structures have significant limitations in enhancing magnetic force. On the one hand, simply increasing the volume or number of magnets can improve the attraction force, but this leads to a bulky structure, increased costs, and fails to solve the problem of magnetic field leakage. On the other hand, ordinary magnetic pole arrangements make it difficult to achieve directional concentration of the magnetic field, resulting in low utilization of the effective adsorption area. Furthermore, traditional designs often neglect the synergistic optimization of magnetic force distribution and mechanical structure, causing the mesh cover to be prone to misalignment or displacement during installation, affecting aesthetics and sealing performance. Especially in the application of long strip mesh covers, it is even more difficult to ensure the uniformity of magnetic force in the linear direction, further limiting the reliability and applicability of the magnetic structure.

[0004] Therefore, it is necessary to invent a magnetic speaker grille installation structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic speaker grille installation structure that improves applicability through the cooperation of the mounting base and anti-offset base, thereby solving the problem of obvious limitations in enhancing magnetic force in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a magnetic horn mesh installation structure, including a mounting base, an anti-deviation seat fixedly connected to the surface of the mounting base, the anti-deviation seat including an iron guide rail fixedly connected to the top of the mounting base and a limiting frame fixedly connected to the outside of the guide rail, a horn groove being formed on the surface of the mounting base, a frame buckle being provided above the horn groove and engaging with the inside of the limiting frame of the anti-deviation seat, a dustproof mesh being fixedly connected inside the frame buckle, a long-side magnet array being provided below the long side of the frame buckle and attracting each other to the guide rail of the long side of the anti-deviation seat, the long-side magnet array being composed of at least two sets of magnetic pole units, each set of units including permanent magnets whose magnetization direction is rotated 90° sequentially, so that the magnetic field of the long-side magnet array is enhanced in the direction perpendicular to the plane of the dustproof mesh, thereby improving the magnetic force.

[0007] Preferably, a plurality of short-side magnet arrays are provided below the short side of the frame buckle. The short-side magnet arrays are composed of axially magnetized N and N pole alternating permanent magnets, which attract each other to the anti-offset seat short guide rail through the short-side magnet arrays.

[0008] Preferably, the top ends of both the short-side magnet array and the long-side magnet array are fixedly connected to a soft magnetic material shielding layer, and the top end of the soft magnetic material shielding layer is fixedly connected to the bottom end of the frame buckle.

[0009] Preferably, one end of the anti-offset seat is fixedly connected to an arc-shaped anti-misalignment frame, and the other end of the anti-offset seat is fixedly connected to a square anti-misalignment frame. Different shaped parts are assembled by the cooperation of the square anti-misalignment frame and the arc-shaped anti-misalignment frame.

[0010] Preferably, a first anti-mistake plastic block is snapped into the inside of the arc-shaped anti-mistake frame. The first anti-mistake plastic block is fixedly connected to the short side of the frame buckle. The snapping and anti-mistake are achieved through the cooperation between the arc-shaped anti-mistake frame and the first anti-mistake plastic block.

[0011] Preferably, a second anti-mistake plastic block is snapped into the inside of the square anti-mistake frame. The second anti-mistake plastic block is fixedly connected to the end of the frame buckle away from the first anti-mistake plastic block. Pinch grooves are provided on both sides of the second anti-mistake plastic block, which can be used to easily pinch and remove the frame buckle from the inside of the anti-offset seat.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] By combining the mounting base and the anti-offset base, and using a 90° rotating magnetic pole arrangement for the long-side magnet array, the magnetic field is concentrated and enhanced on the vertical adsorption surface of the dustproof mesh. Compared with the traditional alternating N and N pole arrangement, this improves the magnetic force while reducing external magnetic field interference. The short-side magnet array adopts an axial alternating N and N pole design, which reduces manufacturing costs while ensuring sufficient adsorption force. The iron guide rail and limit frame of the anti-offset base form a dual positioning, and the asymmetrical structure of the arc-shaped anti-misalignment frame and the square anti-misalignment frame effectively prevents installation misalignment. The soft magnetic material shielding layer further suppresses magnetic field leakage, while the design of the pinching groove makes the disassembly operation more user-friendly. The overall structure enhances magnetic attraction performance while taking into account anti-misalignment, noise reduction, and ease of maintenance. Attached Figure Description

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figure 1-5The magnetic speaker grille installation structure shown includes a mounting base 1. An anti-displacement seat 2 is fixedly connected to the surface of the mounting base 1. The anti-displacement seat 2 includes an iron guide rail fixedly connected to the top of the mounting base 1 and a limiting frame fixedly connected to the outside of the guide rail. A speaker groove 3 is formed on the surface of the mounting base 1. A frame buckle 4 is provided above the speaker groove 3 and engages with the inside of the limiting frame of the anti-displacement seat 2. A dustproof mesh 5 is fixedly connected inside the frame buckle 4. A long-side magnet array 12 is provided below the long side of the frame buckle 4, and the long-side magnet array 12 attracts the guide rail on the long side of the anti-displacement seat 2. The long-side magnet array 12 is composed of... It consists of at least two sets of magnetic pole units, each set of units containing permanent magnets whose magnetization direction is rotated 90° sequentially, so that the magnetic field of the long side magnet array 12 is enhanced in the direction perpendicular to the plane of the dustproof mesh 5, thereby improving the magnetic force. Several sets of short side magnet arrays 11 are arranged below the short side of the frame buckle 4. The short side magnet array 11 is composed of axially magnetized N and N pole alternating permanent magnets. The short side magnet array 11 and the short guide rail of the anti-offset seat 2 are attracted to each other. The top of the short side magnet array 11 and the long side magnet array 12 are both fixedly connected to a soft magnetic material shielding layer 13. The top of the soft magnetic material shielding layer 13 is fixedly connected to the bottom of the frame buckle 4.

[0024] Refer to the instruction manual appendix Figure 1-5 One end of the anti-offset base 2 is fixedly connected to an arc-shaped anti-misalignment frame 7, and the other end is fixedly connected to a square anti-misalignment frame 6. Different shaped parts are assembled through the cooperation of the square anti-misalignment frame 6 and the arc-shaped anti-misalignment frame 7. A first anti-misalignment plastic block 8 is snapped into the interior of the arc-shaped anti-misalignment frame 7. The first anti-misalignment plastic block 8 is fixedly connected to the short side of the frame buckle 4. The cooperation between the arc-shaped anti-misalignment frame 7 and the first anti-misalignment plastic block 8 achieves snapping and anti-misalignment. A second anti-misalignment plastic block 10 is snapped into the interior of the square anti-misalignment frame 6. The second anti-misalignment plastic block 10 is fixedly connected to the end of the frame buckle 4 away from the first anti-misalignment plastic block 8. Pinch grooves 9 are provided on both sides of the second anti-misalignment plastic block 10, allowing for easy pinching and removal of the frame buckle 4 from the interior of the anti-offset base 2. By combining the mounting base 1 and the anti-offset base 2, the magnetic field is concentrated and enhanced on the vertical adsorption surface of the dustproof mesh 5 through the arrangement of the long side magnet array 12 with 90° rotating magnetic poles. Compared with the traditional alternating N and N pole arrangement, this improves the magnetic force and reduces the interference of the external magnetic field. The short side magnet array 11 adopts an axial alternating N and N pole design, which reduces the manufacturing cost while ensuring sufficient adsorption force. The iron guide rail and the limiting frame of the anti-offset base 2 form a double positioning. Combined with the asymmetrical structure of the arc-shaped anti-misalignment frame 7 and the square anti-misalignment frame 6, it effectively prevents installation misalignment. The soft magnetic material shielding layer 13 further suppresses magnetic field leakage, while the design of the pinching groove 9 makes the disassembly operation more user-friendly. The overall structure enhances the magnetic attraction performance while taking into account the anti-misalignment, noise reduction and easy maintenance.

[0025] The working principle of this practical application is as follows:

[0026] Refer to the instruction manual appendix Figure 1-5 During installation, the long-side magnet array 12 of the frame buckle 4 concentrates the magnetic field and guides it to the iron guide rail of the anti-offset seat 2 through its arrangement characteristics, generating a strong adsorption force. At the same time, the short-side magnet array 11 achieves auxiliary fixation by adsorbing the short-side guide rail through alternating N and S poles. When the dustproof net 5 is pressed down with the frame buckle 4, the first anti-mistake plastic block 8 is forcibly matched with the arc contour of the arc-shaped anti-mistake frame 7, and the second anti-mistake plastic block 10 is fitted with the square anti-mistake frame 6. The shape interlocking ensures a unique correct installation position.

[0027] During disassembly, fingers apply upward force through the pinching groove 9 to overcome the magnetic attraction, causing the second anti-foolproof plastic block 10 to detach from the square anti-foolproof frame 6, allowing the frame buckle 4 to be removed as a whole. Throughout the process, the soft magnetic material shielding layer 13 absorbs stray magnetic fields to prevent them from affecting surrounding electronic equipment, while the limiting frame constantly restricts the lateral displacement of the frame buckle 4, ensuring that it will not loosen during long-term use.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
