Abstract
Embodiments of the present concept are directed to medical devices having features that prevent contaminants from infiltrating the housing of the device while providing a mechanism to provide clear auditory sounds to aid a rescuer in providing care to a patient. In one example, a medical device includes a housing having a transmission area associated with an enclosed voice coil. An exterior diaphragm formed integrally with the housing surrounds the transmission area and provides a watertight seal of the transmission area. In addition, the diaphragm is structured to generate a sound that can be heard by the rescuer from the voice coil.
