Description

Technical Field

[0001] The utility model relates to the technical field of speaker grilles, in particular to a dustproof and waterproof speaker grille. Background Art

[0002] The function of the speaker is to convert electrical signals into sound. It is also called a loudspeaker. The speaker is actually a conversion device that converts electrical energy into sound. When different electronic energies are transmitted to the coil, the coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes the paper plate to vibrate. Because the electronic energy changes at any time, the coil of the speaker will move forward or backward, so the paper plate of the speaker will move with it. This action causes the density of the air to change and produce sound. The speakers of televisions and radios are usually covered with speaker nets to prevent dust and ensure the safety of the speakers.

[0003] After searching, a Chinese patent discloses a dustproof speaker mesh cover (authorization announcement number CN207706363U), the outer side of the mesh cover body is fixedly connected to a filter plate, the lower end of the filter plate is fixedly connected to a mesh cloth, a film is arranged at the lower end of the mesh cloth, and a number of filter holes are evenly arranged on the filter plate; a separator is arranged on the filter plate, and the separator is composed of irregular mesh holes on the filter plate that are different from the filter holes. Although the patented technology can combine the mesh cover body and the separator by arranging ordinary filter holes and irregular mesh holes on the filter plate, when the irregular mesh holes are inclined holes, different brightness and darkness can be presented when the filter plate is tilted at different angles, and the three-dimensional visual effect is good, a large number of processes are reduced, and costs are greatly saved. At the same time, a layer of dust-proof mesh cloth is added, which greatly reduces the possibility of dust entering the inside of the speaker and protects the speaker.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that the prior art achieves dustproofing of the speaker mesh by fixing a mesh cloth at the lower end of the filter plate and setting a film at the bottom end of the mesh cloth. However, the fixed connection method makes it difficult to disassemble the dustproof mesh cover, which makes it inconvenient to replace and clean the dustproof mesh cover. At the same time, although the use of the dustproof mesh cover plays a dustproof role, users with higher sound quality requirements need to take out the dustproof mesh cover to avoid affecting the sound quality of the audio.
