TELEPHONE HANDSET HAVING HOUSINGS ASSEMBLED WITHOUT MECHANICAL FASTENERS Abstract of the Disclosure Assembly of handsets is accomplished without the use of mechanical fastenings. Energy directors are provided at the peripheral edges of one of the two housings forming a handset, and the two housings are united by sonic welding. Severe damage can be caused to transducers mounted in the handset by sonic welding, but the use of energy directors directs the sonic energy around the transducers, avoiding damage. The transducers can be held in place by heat staking positioning members. A rigid assembly which is readily amenable to automated assembly is provided.
