Description

Technical Field

[0001] This utility model relates to the field of speaker grilles, and in particular to an anti-static speaker grille. Background Technology

[0002] A speaker grille is a protective accessory installed in front of a loudspeaker (speaker). It is typically made of materials such as metal, plastic, or fabric and has a mesh-like structure. Its core function is to protect the internal components of the loudspeaker while optimizing sound propagation. It is widely used in audio equipment, home appliances, car audio systems, and public address systems. Speaker grilles are generally used to prevent dust, insects, hair, and other foreign objects from entering the loudspeaker, avoiding damage to delicate components such as the diaphragm and voice coil. They also cushion external impacts (such as finger touches or dropped objects), preventing diaphragm deformation or voice coil displacement. Furthermore, speaker grilles prevent accidental touching that could damage the loudspeaker or injure people. In addition, the mesh design of the speaker grille balances protection and sound propagation, ensuring that high-frequency, mid-frequency, and low-frequency sound waves are evenly transmitted, reducing sound distortion.

[0003] However, current speaker grilles are generally formed from metal sheets through stamping, resulting in a relatively simple structure and function. They lack lighting effects and therefore cannot achieve dynamic changes in appearance, leading to a monotonous look that fails to meet users' aesthetic demands. Furthermore, the outer surface of current speaker grilles is prone to dust accumulation due to static electricity, resulting in poor dust protection. Therefore, it is necessary to improve current speaker grilles. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide an anti-static speaker grille, which can effectively solve the problems of existing speaker grilles not having lighting effects and being prone to dust accumulation.

[0030] Please refer to Figures 1 to 3 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a main body layer 10, a light-emitting sheet 20, a reinforcing layer 30, a fixing layer 40, a light-transmitting protective layer 50, and a light-transmitting antistatic coating 60.

[0031] The main body layer 10 has multiple first mesh holes 11 and multiple light-transmitting holes 12 permeating its inner and outer surfaces. The multiple first mesh holes 11 are spaced apart, and a cylindrical body 13 extends inward from the periphery of each first mesh hole 11. Each cylindrical body 13 protrudes from the inner surface of the main body layer 10. The multiple light-transmitting holes 12 are spaced apart and located beside the multiple first mesh holes 11. An annular retaining edge 14 extends inward from the periphery of the inner surface of the main body layer 10, forming a mesh-like groove 101 with the multiple cylindrical bodies 13. In this embodiment, the main body layer 10 is formed from a metal sheet (such as stainless steel or aluminum alloy) through stamping and stretching. The multiple cylindrical bodies 13 are formed by stretching, and the annular retaining edge 14 is formed by stamping and bending. The multiple first mesh holes 11 are regular polygonal through holes, specifically regular hexagonal through holes, but not limited to any particular shape. Correspondingly, the outer contour of the cylindrical body 13 is a regular polygonal prism. The multiple light-transmitting holes 12 are circular.

[0032] The light-emitting sheet 20 includes a flexible circuit board 21, a connecting socket 22, and multiple LED beads 23. The flexible circuit board 21 is embedded in a mesh groove 101. The connecting socket 22 is disposed on the flexible circuit board 21 and is electrically connected to the flexible circuit board 21. The multiple LED beads 23 are all disposed on the front side of the flexible circuit board 21 and are electrically connected to the flexible circuit board 21. The multiple LED beads 23 are respectively located in multiple light-transmitting holes 12. In this embodiment, the flexible circuit board 21 is an FPC, and the flexible circuit board 21 has multiple third mesh holes 201. The multiple cylindrical bodies 13 are respectively inserted into the multiple third mesh holes 201. The multiple third mesh holes 201 are all regular polygonal through holes and are adapted to fit the multiple cylindrical bodies 13.

[0033] The reinforcing layer 30 is mesh-like and adapted to the mesh groove 101. The reinforcing layer 30 is embedded in the mesh groove 101 and stacked on the back of the flexible circuit board 21 to strengthen the overall structure and prevent easy bending and deformation. In this embodiment, the reinforcing layer 30 is made of carbon fiber, which is lightweight and has good structural strength. Furthermore, the reinforcing layer 30 has multiple fourth mesh holes 31, through which the multiple cylindrical bodies 13 are respectively inserted. The multiple third mesh holes 31 are all regular polygonal through holes and are adapted to fit the multiple cylindrical bodies 13.

[0034] The fixing layer 40 is cured and formed in the mesh groove 101. The fixing layer 40 completely covers the reinforcing layer 30 and fixes the reinforcing layer 30 and the light-emitting lamp sheet 20 in the mesh groove 101. In this embodiment, the fixing layer 40 is made of plastic and is formed by injection molding to fill the mesh groove 101. The reinforcing layer 30 and the connecting socket 22 are both embedded and fixed together with the fixing layer 40.

[0035] The light-transmitting protective layer 50 is cured and formed on the outer surface of the main body layer 10. The light-transmitting protective layer 50 completely covers the outer surface of the main body layer 10 and fills each light-transmitting hole 12. The light-transmitting protective layer 50 is formed and fixedly connected to the light-emitting lamp sheet 20. The light-transmitting protective layer 50 has multiple second mesh holes 51, which are respectively aligned and connected to multiple first mesh holes 11 to form sound channels 102. In this embodiment, the multiple second mesh holes 51 are regular polygonal through holes; specifically, the multiple second mesh holes 51 are regular hexagonal through holes, but not limited to any particular shape. Furthermore, the light-transmitting protective layer 50 is made of transparent resin material, which is cured and formed by UV light, making its manufacturing process simple.

[0036] The light-transmitting antistatic coating 60 completely covers the outer surface of the light-transmitting protective layer 50, and the light-transmitting antistatic coating 60 completely covers the inner wall of the second mesh 51, the inner wall of the first mesh 11 and the inner wall of the cylinder 13, so as to play an antistatic role, prevent dust from adhering, and thus achieve the purpose of dust prevention.

[0037] During manufacturing, firstly, a metal sheet is stamped and stretched to form the main body layer 10, and then the light-emitting lamp sheet 20 and the reinforcing layer 30 are prepared. Next, the light-emitting lamp sheet 20 and the reinforcing layer 30 are embedded into the mesh groove 101 in sequence. Then, molten plastic is injected into the mesh groove 101 and cooled and solidified to form the fixing layer 40. Next, a light-transmitting protective layer 50 is formed on the outer side of the main body layer 10. Finally, a light-transmitting antistatic coating is applied to the outer surface of the light-transmitting protective layer 50 to form a light-transmitting antistatic coating 60.

[0038] In use, this product is installed on the speaker equipment and covers the speaker. At the same time, the connection socket 22 is connected to the control system of the speaker equipment through the connection cable. During the operation of the speaker equipment, the control system can control the light-emitting sheet 20. After the multiple LED beads 23 are powered on, they are lit up. The light emitted is emitted outward through the light-transmitting protective layer 50 and the light-transmitting anti-static coating 60 to achieve the light-emitting function. The light-emitting mode can be controlled by the control system of the speaker equipment, such as the light being constantly on, partially lit to form the desired pattern, or flashing in rhythm with the music, etc.

[0039] The key design feature of this invention is that by embedding the light-emitting sheet into a mesh groove and fixing it with a reinforcing layer, a fixing layer, and a light-transmitting protective layer, the product gains a lighting function. It can be connected and used with speaker equipment, thereby achieving dynamic changes in appearance. It has diverse structures and functions to meet users' pursuit of aesthetics. At the same time, the addition of a light-transmitting anti-static coating can prevent static electricity and dust adhesion, thus achieving the purpose of dust prevention.

[0040] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
