Microphone sub-assemblies for direct mounting on a telephone handset inner substrate comprise a tubular housing containing a microphone having terminal pins electrically connected within the tubular housing to leads extending through the housing tubular wall. The leads provide contact springs for spring biased contact with conductive lands on the substrate. In one embodiment, the contact springs comprise coiled springs and, in another embodiment, the contact springs comprise leaf springs terminating in arcuate cam surfaces.

Acoustic component sub-assemblies for direct mounting on a telephone handset inner substrate comprise a tubular housing containing a component having terminal pins electrically connected within the tubular housing to coil springs extending outwardly through an open end of the tubular housing. The coil springs serve as component terminals for spring biased contact with conductive lands on the substrate. The tubular housing is press fitted within a seat on the substrate and contacted by the handset outer housing for being tightly clamped within the substrate seat.

Impact-tolerant mounting of acoustic components

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.

A hinge assembly which has a limited number of stable positions and in which the hinge automatically moves to the closest of such stable positions is disclosed. The movement of the hinge is accomplished in one illustrative embodiment by positioning the protrusion on one of a pair of ramps inclined opposite to one another and toward the adjacent recess so that the parts of the hinge rotate relative to one another, moving the protrusion into the adjacent recess. The protrusion is pressed against the ramps and the grooves by a connecting portion that joins the arm portions and is flexed when the hinge parts are assembled so as to bias the arm portions toward one another.

A pen computer has a double hinge connector and a first member which is rotatably connected to the connector. The first member has a pen sensitive screen. A second member, having a flat surface, is also rotatably connected to the connector. The pen computer is in a closed position when an angle between the first and second members is equal to zero degrees. The pen computer is in an open position when the angle between the first and second members is substantially equal to 180 degrees. When the pen computer is in the open position, the flat surface of the second member is substantially level with the pen sensitive screen of the first member, such that the flat surface is operable as a palm rest for facilitating the use of the pen sensitive screen.
