Speakers are everywhere these days. I have some in my car, I have two on my desk (currently playing Vivaldi). In our last blog, we talked about rattling/pinging that can be present in different environments. As discussed in that blog, we suggest foam/sponge to absorb that vibration in the application. A speaker gasket may do one of those functions, but it can serve a few other functions.
What does a Speaker Gasket do?
A speaker gasket material does a few things:
- It reduces rattling/pinging/banging that can happen with all the vibration that may be present between the speaker, and the subwoofer.
- The gasket can help create a seal to direct the sound in the correct direction, preventing any sound leakage.
- Depending on the environment the speaker may be in- it can prevent low grade ingress or dust, and water that could be present- especially dust.
Types of Speaker Gasket Materials to Test in your Application
-Open Cell Polyurethane Foam
-Closed Cell Neoprene Sponge, Soft, Medium, Firm
-Closed Cell EPDM Sponge, Soft, Medium, Firm
-Cork Rubber/Composite Rubber
What kind of Speaker Gaskets does NEDC do?
NEDC manufactures custom speaker gaskets, for higher performance applications.
Should I get an adhesive backing with my Speaker Gasket?
I would say this depends on the geometry – however, a liquid adhesive can be messy, and is easier to make mistakes. The factory gasket you would get from us – you can get a special tailored adhesive backing to match the substrate your gasket is being adhered to.
3M products such as:
- 3M 9485PC
- 3M 467MP
- 3M 9472
Are some common tapes that we may suggest to try. Since NEDC is a 3M converter, we can provide these gasketing materials with adhesive backing.
