    摘要： A microphone (10) for a two-way radio has front (12) and rear (14) housing assemblies, a PTT button (48) and a detachable power cable (18). The front housing (20) has a microphone opening (22) and an integrally formed hoop (36) on the lower part of the housing. A waterproof membrane (32) covers the opening and protects a microphone cartridge (24). A grill (34) snaps to the front housing, securing the membrane in place. The PTT button actuates a PTT switch through an elastomeric boot (50) which seals the microphone and also acts as a return spring for the PTT button. The rear housing (40) has a hoop receiver (38) on the lower part of the housing to receive the hoop on the front housing, and the PTT button fits into the side of the housing. The detachable power cable snaps into the microphone, and is held in place with a locking collar (58) which engages the hoop. When the entire microphone is assembled, the locking collar is retained in the hoop to provide additional securing force, and an o-ring seal (46) is radially compressed between the front housing and the rear housing to provide a water-tight seal around the microphone cartridge.
