  • Patent number: 4675903
    Abstract: The generally rectangular cross section of a telephone handset handle extends through a microphone portion of the handset. The microphone portion is angled about 38 degrees from the handle. The handle has a width of about 1.5 inches and a depth of about 0.7 inch to meet the requirements of 98% of the user population. A speaker portion, angled about 15 degrees from the handle, has a concave depression to be seated against a user's ear. The distance between the center of the speaker depression and the microphone cavity is about 5.8 inches. The microphone portion is about two inches long and has grooves extending to its end. Baffles 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 without the need for adhesive or additional fasteners. The speaker and holder are then positioned in a base section of the handset without the need for adhesive or additional fasteners.
