Sound and sealing pull in opposite directions
Membrane and mesh are matched to the port and cut as one laminated part, so the acoustic path is set by the drawing.
Headphones & Audio Devices
Acoustic membranes, dust mesh, damping foam, and port adhesive that keep water out without muffling the sound.
Application
Protect the port without muffling the sound
An earbud or speaker port has two jobs that fight each other. It has to pass sound, and it has to stop water, sweat, and pocket dust. The membrane and the mesh settle that fight, and they are usually cut as a pair.
Inside the housing, foam damps the cavity and closes gaps that would buzz. Double-sided adhesive holds the driver, the cover, and the mesh in place without spreading over the opening.
Registration matters here more than almost anywhere. A mesh that shifts covers the hole it was meant to protect, and an adhesive ring that drifts changes how the port sounds. Our combination lines are built for that alignment.

What the assembly asks for
The problems buyers in this industry bring to the plant, and how the floor handles each one.
Adhesive must stay off the port
Adhesive rings are registered to the opening on the combination lines and checked on the 2.5D vision machine.
Parts are tiny and numerous
Laser samples confirm the outline, then the rotary line carries the volume on a web.
Sweat and humidity
Membranes block liquid at the port while the housing can still breathe.
Parts from the plant
Photographed for the company profile. Shapes are customer-specific, so treat them as examples of the work, not stock items.
Delivery formats
Parts arrive the way your line places them
Tell us how the part goes on: by hand, in a fixture, or from a web. Each format below comes from a named machine on the floor.
Kunlun KL-QP-350 sheet cutters × 2
Sheets
Parts kept on a carrier sheet, counted and stacked, for hand placement or low-volume fixtures.
Kunlun KL-FTJ-1300 CNC slitter, Hadesheng rotary
Rolls
Parts cut on a continuous web and wound to width, for long runs and feeders that pull from a roll.
Kunlun and Hongwen laminators × 16
Laminated stacks
Membrane, mesh, foam, or film combined with adhesive and liner before the cut, so one part replaces several.
Han's Laser CMA0604-B-A
Laser samples
First articles cut from the drawing without a tool, for fit trials before steel is committed.

Questions buyers ask
If yours is not here, put it in the quote form. We reply within one business day.
Can you match a membrane to our acoustic target?
Send the target or the current part. We propose membrane constructions and cut samples for your acoustic test. We do not quote acoustic values we have not measured on your design.
Can mesh and membrane be cut as one part?
Yes. They can be laminated with the adhesive ring and cut together, so one piece goes onto the port.
What should we send for a quote?
A drawing or a marked photo, where the part sits, the sample quantity, and the yearly volume. If the material grade is on the print, include it. If not, describe the job the part has to do.
What are the lead time and trade terms?
The stated lead time is 30 days. Trade is EXW. Payment is T/T, PayPal, or cash, in USD, EUR, HKD, or CNY.
