Abstract
Device with ultrasonic transducer and method for manufacturing same. A device is provided, having an ultrasonic transducer, which includes a membrane and a cover element. A coupling medium entirely fills an interspace between the membrane and the cover element, and extends from the interspace into a reservoir space which communicates with the interspace.
Claims20
A device, comprising:
- an ultrasonic transducer having a membrane;
- a cover element which is spaced from the ultrasonic transducer;
- and
- a coupling medium, which entirely fills an interspace between the membrane and the cover element, and which extends from the interspace into a reservoir space which communicates with the interspace.
