Description

Technical Field

[0001] This utility model relates to a speaker grille, specifically a novel metal speaker grille. Background Technology

[0002] A metal speaker grille is a metal mesh used to protect speakers, typically made of alloys such as copper, aluminum, stainless steel, and nickel. Its mesh density can be adjusted according to different equipment requirements and musical characteristics, and it usually consists of multiple layers to improve its filtering effect.

[0003] Existing metal speaker grilles typically lack a structure for cleaning dust. When a lot of dust adheres to the surface of the metal speaker grille, it can only be cleaned using external tools. Furthermore, during cleaning, dust can easily fall into the inner side of the metal speaker grille and negatively impact its internal structure. Utility Model Content

[0004] The purpose of this invention is to provide a novel metal speaker grille. Through the protective panel on the self-cleaning component, the protective panel rotates synchronously with the cleaning brush, which can prevent dust from falling into the inner side of the metal grille during cleaning, thus protecting the inner structure of the metal grille.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel metal speaker grille includes a protective ring and a metal panel fixed inside the protective ring. A positioning shaft is installed on the metal panel, and the central axis of the metal panel coincides with the central axis of the positioning shaft. A half-rod and a protective panel are fixed on the positioning shaft. A slot is provided on the lower end face of the half-rod, penetrating the end of the half-rod away from the positioning shaft. A positioning strip is fixed inside the slot, and a cleaning brush is provided on the lower end face of the positioning strip. An opening penetrating both the upper and lower ends of the protective panel is provided. A leak-proof frame is inserted at the end of the protective panel away from the positioning shaft. The leak-proof frame is used to seal the opening on the lower end face of the protective panel, thereby receiving dust. A receiving plate is provided at the end of the positioning shaft away from the protective panel. The receiving plate is a cavity structure with an opening on the upper end face and a hollow interior. A discharge port is provided at the end of the receiving plate away from the positioning shaft.

[0006] Preferably, a number of mesh holes are provided on the metal panel, penetrating both sides, and the mesh holes are evenly distributed on the metal panel.

[0007] Preferably, buffer pads are provided on both sides of the slot opening. Both buffer pads are fixed to the half rod. The two buffer pads are used to prevent the positioning strip from accidentally slipping out of the slot. The positioning strip will pass through the two buffer pads when it is installed or removed, and a certain amount of friction needs to be overcome in this process.

[0008] Preferably, the leak-proof frame closes the opening on the lower end of the protective panel, allowing dust to fall into the protective panel, and a handle is fixed to the end of the leak-proof frame away from the positioning axis.

[0009] Preferably, both the half-bar and the protective panel are horizontally arranged, and the half-bar and the protective panel are distributed on both sides of the metal panel.

[0010] Preferably, a first support plate and multiple second support plates are provided below the metal panel. The positioning shaft is installed on the first support plate, and the multiple second support plates are all fixed to the receiving plate. The first support plate and the multiple second support plates are all fixedly connected to the protective ring, so that the structure of the positioning shaft and the receiving plate remains stable.

[0011] Preferably, a strip-shaped hole is provided on the metal panel, extending through both sides, and a notch is provided on the side of the protective ring where the receiving plate is located. The strip-shaped hole is used to allow dust on the upper surface of the metal panel to fall into the cavity of the receiving plate, and the notch is used to pour out the dust inside the receiving plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model has a positioning shaft, a half rod and a cleaning brush set inside the protective ring. By rotating the half rod, the cleaning brush can be moved on the upper surface of the metal panel and the dust on the surface of the metal panel can be cleaned. Therefore, it can achieve quick dust removal without the need for external dust removal tools, making the dust removal operation more convenient.

[0014] 2. In this utility model, a protective panel is set on the positioning shaft. When the protective panel rotates synchronously with the cleaning brush, it can receive the dust scraped off by the cleaning brush, preventing dust from falling into the inner side of the metal mesh during cleaning, thus achieving the effect of structural protection for the inner side of the metal mesh.
