Speaker Grill Stainless Steel

Speaker Grill is usually found in front of the earphone and loudspeaker which mounted directly over the face of the speaker driver. It maily used to protect the driver element, speaker internals and other audio components from foreign objects while still allowing the sound to clearly pass. However, because it sits in the direct path of the driver, the grille interacts with the sound produced. A suitable compromise between protection and sound quality must be made based on the speaker's application.

We supply various kinds of audio accessories, speaker accessories, TV signal amplifier etc. audio accessories including speaker mesh, speaker pad, speaker grille, speaker port tube, speaker terminal cup, speaker handle, protective corner, speaker grill, speaker ring, magnet cover

Other types available: Woven Speaker Mesh

Technology:

Etching is the process of using strong acid or mordant to cut into the unprotected parts of a metal surface to create a design in intaglio in the metal (the original process—in modern manufacturing other chemicals may be used on other types of material). As an intaglio method of printmaking it is, along with engraving, the most important technique for old master prints, and remains widely used today.

The chemical etching process is a burr-free and stress-free manufacturing process. Chemical etching also provides consistent hole opens throughout the part. Compared to using a mesh (woven) screen, Steellong provides a flat pattern where particles are less likely to become trapped in the weaving. A flat pattern also provides consistent hole openings whereas woven screens can stretch and become distorted. the metal etching screens can be designed into a variety of shapes, percentage open-area, and in a variety of metals. Brittle metals and thin foils are much easier to etch than stamp, or machine in other traditional forms or manufacturing.

Etching is also used in the manufacturing of printed circuit boards and semiconductor devices (see Etching (microfabrication) ), on glass, and in the preparation of metallic specimens for microscopic observation.

Copper was always the traditional metal, and is still preferred, for etching, as it bites evenly, holds texture well, and does not distort the colour of the ink when wiped. Zinc is cheaper than copper, so preferable for beginners, but it does not bite as cleanly as copper, and it alters some colours of ink. Steel is growing in popularity as an etching substrate. Prices of copper and zinc have steered steel to an acceptable alternative. Line quality of steel is less fine than copper but finer than zinc. Steel has a natural and rich aquatint. Steel is virtually impossible to reclaim though the price and availability make it still more cost effective

perforated metal is seen almostly everywhere in today's world: as decorative architectural panels, light diffusers, air diffusers, and more. Perforated metal panels and plates have varied uses as screening to ventilation.

The economical process of making lightweight perforated metal allows Petro-Wire and Steel to custom design architectural panels and stainless steel plates with a variety of holes, shapes and designs. Depending on the size and shape of the perforated openings and the gauge, punched metal can become many things.

From a behind-the-scenes workhorse used to screen and filter a variety of materials, to a visually appealing light diffuser or air diffuser for architectural applications, perforated sheet metal is the solution that can even perform artistically as a display. Perforated decorative metal is especially great for making architectural panels that give buildings an attractive design touch.
