I'm getting my feet wet with MEMS microphones for a personal project and eventually will want to integrate the sensor into a device housing.
A gasket needs to be used between the sound port and the housing. The gasket material and geometry chosen has a significant affect on the acoustic performance since it forms part of the acoustic channel with the housing, and my project is sensitive to this.
I'm looking for advice on how can one practically prototype the sensor-housing interface.
Are there vendors of miniature gaskets that will do small volume orders at reasonable prices? I think I'll be looking for something that's roughly 0.6mm inner diameter, 2mm outer diameter, and less than 0.5mm thick.
I presume some form of adhesive is also typically used to keep the sensor, gasket, and housing bonded together. Any suggestions on what type?
