Abstract

Abstract The generally rectangular cross section of a telephone handset handle (20) extends through a microphone portion (24) of the handset. The microphone portion (24) is angled about 38 degrees from the handle (20). The handle (20) has a width of about 1.5"(38 mm) and a depth of about .7"(18 mm) meet the requirements of 98% of the user population. A speaker portion (22), angled about 15 degrees from the handle (20), has a concave depression (30) to be seated against a user's ear. The distance between the center of the speaker depression (30) and the microphone cavity (26) is about 5.8"(147 mm). The microphone portion (24) is about two inches (53 mm) long and has grooves (28) extending to its end. Baffles (52, 54) extend across the hollow of the handle to acoustically isolate the speaker and microphone portions of the handset. To facilitate assembly, the connector and microphone are first fixed to a holder (64) without the need for adhesive or additional fasteners. The speaker (40) and holder (64) are then positioned in a base section of the handset without the need for adhesive or additional fasteners. The holder (64) may restrain a magnet element (110). A top section (44) of the handset is secured under a lip (98) at one end and by a spring clip (100) at the other end.
