Abstract
A microphone-speaker assembly includes a housing, a microphone, a speaker, and a push-to-talk switch. The housing supports the speaker for movement between a first position in which the switch is not activated and a second position in which the switch is activated. The switch is located in a water resistant chamber along with a circuit board. The speaker moves toward the circuit board when it moves from the first position to the second position. A seal supports the speaker for movement between the first and second positions. A method of activating a microphone in a microphone-speaker assembly includes the steps of applying force to a speaker of the assembly, and moving the speaker thereby to activate the switch thereby to activate the microphone. The speaker moves relative to a push to talk switch, deforming a resilient membrane that helps to form a water resistant chamber in the assembly.
