Speaker Grille Perforated
Speaker Grille Perforated 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
Production 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.
