Speaker cover's characteristics and function.

The characteristics and function of the speaker cover.

The speaker mesh using the principle of aerodynamics, according to the results of on-site environmental wind tunnel tests, it is processed into a certain geometric shape, opening rate and different combinations of hole types to block the wind and dust suppression wall, so that when the circulating air (strong wind) goes through the wall, the airflow of up and down disturbance is formed inside the wall, thus preventing dust. 

Stainless steel, SPCC, aluminum plate are commonly used material. the shapes of mesh are usually round, square and hexagonal. thus to make the sound from the speaker to the outside, and the speaker for dust protection. Audio speaker grille are mostly made of  pvc, stainless steel, SPCC and aluminum.

Speaker mesh is widely used in digital products, electronic products, communication equipment and other industries, such as cell phones, video cameras, DVDs, computers and so on.

Due to different materials, it can be divided into  categories like Stainless steel  speaker cover, SPCC speaker cover, Aluminum speaker cover, etc.

General material thickness: 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.8mm, 1.0mm, etc. It can be customized according to customer requirements.

The diameter of the hole is φ0.6mm, φ0.7mm, φ8mm, φ1.0mm, φ1.2mm, φ1.5mm, φ2.0mm, φ2.0mm, etc.

Audio speaker mesh product characteristics：

1> UV resistance： The surface of the speaker mesh is treated with Painting, which can absorb the UV rays from the sunlight and slow down the oxidation rate of the material itself, so that the speaker mesh has better anti-aging performance and longer service life. At the same time, the UV transmittance is too low, which can avoid sunlight damage.

2> Flame retardant: metal material can meet the requirements of fire safety production.

3> Impact resistance:  Passed the impact force testing,  The speaker mesh does not break when a steel ball of ( 1kg) is dropped freely at 1.5m from the peak of the wave.

4> Anti-static: The surface of the speaker grille is finished by electrostatic spraying, which can oxidize and decompose the organic dirt attached to the sunlight.
