Abstract
Microphone sub-assemblies for direct mounting on a telephone handset inner substrate comprise a tubular wall containing a microphone comprising a cylindrical can and elongated terminal pins extending from the can. The tubular wall is formed from a strip of an elastomeric material wrapped around and adhered to the microphone with the microphone terminal pins extending directly through the wall, in hermetic fit therewith, and radially from the wall. The sub-assembly is mounted in a telephone internal substrate by inserting the microphone terminal pins into a connector on the substrate. Both the sub-assembly and the substrate are firmly secured within a telephone housing with an open end of the tubular housing aligned with a sound admitting port through the telephone housing.
