TELEPHONE HANDSET WITH TRANSMITTER HAVING A ONE PIECE GASKET FOR SEALING AND HOLDING OF TRANSMITTER MEMBERS Abstract of the Disclosure A telephone handset is formed from two elongate hollow concave parts, joined at their peripheries, with a circular recess at one end of the lower part. A transmitter assembly is positioned in the recess and comprises a transmitter, a cup-shaped member positioned on the back of the transmitter and a resilient tubular member surrounding the transmitter and at least the lower or front part of the cup-shaped member. The tubular member has a radially inward projecting rim at its front or lower end extending over the front of the transmitter and a similar rim at its rear end engaging over a projection on the cup-shaped member. The resilient tubular member retains the transmitter and cup-shaped member together, and acoustically seals them together and also acoustically seals the front of the transmitter to the base of the recess. - i -
