Abstract
An ultrasonic transducer (10) includes a housing (12) having a main section (14) and a base section (16). Retainer elements (20) on the main and base sections (14 and 16) of the housing (12) are engageable only when the main and base sections of the housing are in a predetermined orientation relative to each other. The retainer elements (20) press the main and base sections (14 and 16) of the housing (12) together and securely interconnect the main and base sections of the housing. A diaphragm (82) is formed in an end portion of the main section (14) of the housing (12) opposite from the retainer elements (20). A ridge (88) projects axially outward from the diaphragm (82) to protect the diaphragm and decouple the diaphragm from a side wall (74) of the housing (12). Acoustically absorptive material (114 and 116) is disposed in the housing.
