Description

Technical Field

[0001] This utility model relates to the field of speaker equipment technology, and in particular to an installation structure for a speaker grille. Background Technology

[0002] In the production and use of speaker equipment, the speaker grille, as a key component that protects the speaker unit, filters impurities, and also serves as an aesthetic element, directly impacts the speaker's production efficiency, operational stability, and ease of maintenance. Currently, the mainstream speaker grille installation methods on the market fall into two main categories: one is to fix the grille to the cabinet using screws and other fasteners. While this method ensures a certain level of connection stability, it requires aligning each screw hole and tightening it individually during installation, which not only increases production assembly steps and reduces production efficiency but may also cause the grille to deform due to uneven screw tightening force, affecting the speaker's aesthetic appearance; the other type uses a snap-fit ​​connection. However, relying solely on the cooperation of the snaps and slots for fixation makes the snaps prone to loosening or even falling off, and it can also produce abnormal noises, affecting the speaker's user experience. Utility Model Content

[0003] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes an installation structure for a speaker grille.

[0004] The above objective is achieved through the following technical solution:

[0005] A speaker grille mounting structure includes a cabinet and a speaker located on the front side of the cabinet. A grille is fitted over the front side of the speaker. A rectangular annular groove for mounting the grille is provided on the front side of the cabinet. The grille includes a rectangular frame and a grille. The edge of the rectangular frame is provided with a plug plate that can be inserted into the rectangular annular groove. Hook holes are provided on both the left and right sides of the rectangular annular groove. Barbs that can be hooked into the hook holes are provided on both the left and right sides of the plug plate. A transverse slot is provided in the middle of the barb. A locking post that can be locked into the transverse slot is provided in the rectangular annular groove at the position corresponding to the hook hole.

[0006] In some embodiments, the opening of the transverse slot is provided with a guide slope.

[0007] In some embodiments, the rectangular frame, the plug-in plate, and the barb are made of a single piece of plastic.

[0008] In some embodiments, the mesh cover is made of metal.

[0009] In some embodiments, the interior of the enclosure includes a central space and side spaces located on the left and right sides of the central space, and a horn and a mesh cover are provided on the front side of both side spaces.

[0010] In some embodiments, phase-reversing bends are also provided in both of the side spaces.

[0011] In some embodiments, a main control board and a CD processor are disposed in the central space, and function buttons are disposed on the front side of the central space.

[0012] In some embodiments, a rear plate is detachably mounted on the rear side of the central space by screws, and the main control board is disposed on the rear plate.

[0013] In some embodiments, an antenna is rotatably mounted on the rear plate, and the antenna can be rotated to a vertically upward shape or placed horizontally for horizontal storage.

[0014] In some embodiments, a hook is also provided on the rear side of the rear plate, and the antenna rests against the hook when it is in a horizontally retracted position.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] 1. This mounting structure features a rectangular annular groove on the front of the speaker enclosure and a connector plate along the rectangular frame edge of the grille. During installation, simply align the connector plate with the rectangular annular groove and insert it for initial positioning. Simultaneously, the barbs on both sides of the connector plate automatically engage with the hook holes within the rectangular annular groove, eliminating the need for screws, screwdrivers, or other additional tools, significantly simplifying the installation process. Compared to traditional screw fixing methods, this reduces assembly time by more than 50%, significantly improving speaker production and assembly efficiency and reducing labor costs.

[0017] 2. Unlike existing single-buckle fixing methods, this structure innovatively features a horizontal slot in the middle of the hook and a locking post corresponding to the hook hole within the rectangular groove. When the hook is engaged in the hook hole, the locking post precisely engages in the horizontal slot, forming a double-fixing structure. This design effectively disperses the vibration stress generated during speaker use, preventing the hook from loosening or falling off due to long-term vibration, ensuring the grille is stably fixed to the cabinet for a long time, and effectively protecting the speaker unit.

[0023] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0024] like Figures 1-5 As shown, this embodiment provides an installation structure for a speaker grille, including a cabinet 1 and a speaker 2 located on the front side of the cabinet 1. A grille 3 is covered on the front side of the speaker 2. A rectangular annular groove 4 for mounting the grille 3 is provided on the front side of the cabinet 1. The grille 3 includes a rectangular frame 5 and a grille 6. The edge of the rectangular frame 5 is provided with a plug plate 7 that can be inserted into the rectangular annular groove 4. Hook holes 8 are provided on both the left and right sides of the rectangular annular groove 4. Barbs 9 that can be hooked into the hook holes 8 are provided on both the left and right sides of the plug plate 7. A horizontal slot 10 is provided in the middle of the barb 9. A locking post 11 that can be locked into the horizontal slot 10 is provided in the rectangular annular groove 4 at the position corresponding to the hook hole 8.

[0025] When installing the mesh cover 3, first align the plug plate 7 with the opening direction of the rectangular annular groove 4, ensuring that the barbs 9 and the hook holes 8 on the left and right sides of the rectangular annular groove 4 are on the same straight line, completing the initial positioning; push the mesh cover 3 along the depth direction of the rectangular annular groove 4, so that the plug plate 7 is gradually inserted into the rectangular annular groove 4. During this process, the barbs 9 on the left and right sides of the plug plate 7 undergo slight elastic deformation due to the compression of the inner wall of the rectangular annular groove 4. When the barbs 9 move to the position of the hook hole 8, the barbs 9 reset under their own elastic action, and their hook-shaped structure automatically embeds into the hook hole 8, forming an initial fixation in the front and back direction, preventing the mesh cover 3 from coming out in the opposite direction of the depth of the rectangular annular groove 4; when the barbs 9 are fully hooked into the hook hole 8, the locking post 11 in the rectangular annular groove 4 corresponding to the position of the hook hole 8 will simultaneously engage into the transverse locking slot 10 in the middle of the barbs 9. At this time, the locking post 11 and the transverse locking slot 10 form a vertical limit, restricting the displacement of the barb 9 in the vertical direction, preventing it from shifting or coming off the hook hole 8 due to external forces such as vibration and collision, and finally achieving double fixation to ensure that the mesh cover 3 is firmly installed on the box 1.

[0026] Furthermore, a guide slope 21 is provided at the opening of the transverse slot 10. During the installation of the mesh cover 3, when the plug plate 7 is inserted into the rectangular annular groove 4 and the barb 9 gradually approaches the hook hole 8, the locking post 11 in the rectangular annular groove will first contact the guide slope 21 at the opening of the transverse slot 10. As the insertion action continues, the locking post 11 slides along the guide slope 21, and the component force generated by the slope will force the barb 9 to undergo slight elastic deformation (slightly tilting away from the locking post), providing clearance space for the locking post 11 to enter the transverse slot 10. When the barb 9 is fully hooked into the hook hole 8, the locking post 11 just slides past the guide slope 21 and enters the interior of the transverse slot 10. The barb 9 resets under its own elastic action, realizing the precise engagement of the locking post 11 and the transverse slot 10.

[0027] In this utility model, the rectangular frame 5, the plug-in plate 7, and the barb 9 are integrally formed by injection molding. The plastic material itself has a certain elasticity and toughness, which allows the barb 9 to smoothly hook into the hook hole 8 of the rectangular ring groove 4 through elastic deformation during installation. At the same time, in the cooperation between the locking post 11 and the transverse locking slot 10, the micro-elasticity of the plastic can compensate for the assembly gap and ensure a tight fit. The integrally formed structure avoids the risk of loosening of the separate connection, ensures the connection strength between the plug-in plate 7 and the rectangular frame 5, and meets the structural stability when inserted into the rectangular ring groove 4.

[0028] The mesh cover 6 is made of metal. The metal mesh cover 6 (such as iron mesh or aluminum mesh) is fixed to the plastic rectangular frame 5 by welding, snap-fitting or riveting. The high strength and rigidity of the metal resists external impacts and effectively protects the speaker 2 inside. At the same time, the uniform aperture of the metal mesh can ensure sound penetration and prevent dust and foreign objects from entering the speaker unit.

[0029] See Figure 3 As shown, the interior of the enclosure 1 includes a central space 51 and side spaces 52 located on the left and right sides of the central space 51. A speaker 2 and a mesh cover 3 are provided on the front side of each of the two side spaces 52. A bass reflex tube 61 is also provided in each of the two side spaces 52. A main control board 71 and a CD processor 72 are provided in the central space 51. Function buttons 73 are provided on the front side of the central space 51.

[0030] The enclosure 1 is divided into a central space 51 and left and right side spaces 52. The side space 52 is designed to accommodate the speaker 2 and the bass reflex port 61. The speaker 2 is installed on the front of the side space 52, with its sound output direction facing outwards from the enclosure. The bass reflex port 61 is connected to the internal cavity of the side space 52, forming an acoustic resonance channel. The central space 51 is independent of the side space 52 and is used to house the main control board 71 and the CD processor 72, avoiding mutual interference between electronic components and acoustic components. At the same time, the function buttons 73 on the front of the central space 51 are electrically connected to the main control board 71, forming an operation control link.

[0031] Furthermore, a rear plate 81 is detachably installed on the rear side of the central space 51 by screws. The main control board 71 is located on the rear plate 81. An antenna 91 is also rotatably installed on the rear plate 81. The antenna 91 can be rotated to a vertically upward position or placed horizontally for storage. A hook 92 is also provided on the rear side of the rear plate 81. When the antenna 91 is in the horizontal storage position, it abuts against the hook 92.

[0032] The rear panel 81 on the rear side of the central space 51 is detachably connected to the housing 1 by screws, and the main control board 71 is fixedly installed on the rear panel 81. When it is necessary to repair or replace the main control board 71, simply unscrew the screws connecting the rear panel 81 and the housing 1, and the rear panel 81 along with the main control board 71 can be removed from the rear side of the housing 1 without disassembling the mesh cover 3 on the front side of the housing or the components of the side space 52, thus achieving independent disassembly and assembly of the main control board 71.

[0033] The antenna 91 is rotatably mounted on the rear panel 81 and has two working modes: one is a vertical upward mode, when the speaker needs to receive wireless signals (such as Bluetooth or WiFi signals), the antenna 91 is rotated to make it vertical. In this mode, the antenna signal reception angle is wider and the coverage area is larger, which can reduce signal blockage and improve the stability of wireless connection; the other is a horizontal storage mode, when the speaker does not need to use the wireless function or needs to be stored or moved, the antenna 91 is rotated to make it horizontal. At this time, the antenna 91 can be abutted against the hook 92 on the back side of the rear panel 81. The antenna position is fixed by the limiting action of the hook 92 to prevent the antenna from shaking or being damaged.

[0034] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
