Abstract
A process for the manufacture of a speaker cover comprises loading the speaker cover into a plasma chamber, introducing a fluoro monomer into the plasma chamber, pulsing plasma for processing, removing any excess monomer gas from the plasma chamber, and removing the speaker cover from the plasma chamber.
Claims20
A speaker product comprising:
- a housing;
- at least one driver positioned substantially within the housing;
- and
- a speaker cover coupled with the housing;
- the speaker cover comprising a woven or knit material having an initial first acoustic transparency and a plasma coating on the woven or knit material causing a second acoustic transparency, wherein there is no statistically significant difference in acoustic transparency between the first initial acoustic transparency and the second acoustic transparency.

A speaker product comprising:
- a housing;
- at least one driver positioned substantially within the housing;
- and
- a speaker cover coupled with the housing;
- the speaker cover comprising a woven or knit material having an initial first acoustic transparency, the woven or knit material treated by a plasma process causing a second acoustic transparency, wherein there is no statistically significant difference in acoustic transparency between the first initial acoustic transparency and the second acoustic transparency, the plasma process comprising:
- receiving the material into the plasma chamber;
- introducing a fluoro monomer into the plasma chamber;
- pulsing plasma for processing;
- removing any excess monomer gas from the plasma chamber;
- and removing the material from the plasma chamber.
