Smartphone Speaker & Receiver Dust Mesh in 304 Stainless Steel (AISI 304 (1.4301)) is used for sealing smartphone receiver and loudspeaker openings against dust and water while passing sound with a controlled acoustic resistance. The alloy gives good general corrosion resistance in atmosphere and fresh water and is essentially non-magnetic (annealed), with a practical service limit of approx. +450 °C continuous.

Where 304 Stainless Steel Smartphone Speaker & Receiver Dust Mesh Is Used
- Smartphone OEMs: die-cut meshes behind receiver slots and bottom speaker grilles.
- Tablet & laptop makers: larger speaker meshes tuned for bass response.
- Repair parts suppliers: adhesive-backed replacement meshes for screen and housing repairs.
- Rugged device makers: IP68 designs combining mesh with a hydrophobic membrane.
Ordering Smartphone Speaker & Receiver Dust Mesh in 304 Stainless Steel
- Acoustic resistance: Specify MKS Rayl, not only hole size; it sets how much the mesh damps high frequencies.
- Die-cut shape: Length, width and corner radius must clear the speaker port with a 0.3–0.5 mm adhesive land.
- Adhesive: Double-sided pressure-sensitive adhesive rated for drop and heat-cycle testing.
Mistakes to Avoid with Smartphone Speaker & Receiver Dust Mesh
- Choosing the finest mesh available, which muffles the speaker and fails acoustic tuning.
- Omitting the adhesive land, so glue squeezes into the open area and changes resistance.
