Sound Metal Dome Layer

Sound Metal Dome Layer

The Shanyo sound metal dome layer is a tactile contact solution built for stable signal performance in consumer audio devices. Produced in Qingdao with in-house tooling, each layer is inspected under IATF 16949 and our ISO 9001, 14001, 45001 integrated management system.

Sound metal dome layers are engineered for headphones, smart speakers, remote controls and portable audio equipment where reliable, low-resistance contact matters. Each dome is formed from precision stainless steel and assembled onto a polyester carrier film, giving a consistent actuation force and a crisp tactile feel that users notice the moment they press a button.

Why Choose Shanyo Sound Metal Dome Layers

• Stable contact resistance below 100 mO for clear, noise-free signal transmission.
• Tight actuation-force tolerance across every dome in a production run.
• Life cycle rated above 1,000,000 presses for long-term durability.
• Custom dome diameter, height and arrangement matched to your membrane stack.
• Clean-room assembly and 100% appearance inspection before shipment.

Applications in Audio Products

From earphones and Bluetooth speakers to handheld players and karaoke microphones, sound metal dome layers sit beneath the keypad film and convert a light press into a dependable electrical contact. Our engineering team works from your drawing or sample to tune the dome geometry, so the click feel and return force match the intended user experience.

Manufacturing and Quality

Shanyo operates in-house stamping, dome placement and die-cutting, which keeps lead time short and tolerances tight. Every sound metal dome layer is RoHS and REACH compliant, and can be supplied with LGF (light guide film), FPC pads or adhesive backing for easier integration on your assembly line.

Tell us your layer size, dome arrangement and circuit layout, and we will manufacture to drawing and support you from prototyping through mass production.
