Abstract
Systems and methods for a transducer assembly for a vehicle having a resonating surface. The transducer assembly comprising a housing, a spacer connected to the housing, and a piezoelectric assembly disposed between the spacer and the housing. The spacer is configured to connect to the resonating surface to form an air gap between the resonating surface and the piezoelectric assembly.
Claims20
A transducer assembly for a vehicle having a resonating surface, the transducer assembly comprising:
- a housing;
- a spacer connected to the housing;
- and
- a piezoelectric assembly disposed between the spacer and the housing,
- wherein the spacer is configured to connect to the resonating surface to form an air gap between the resonating surface and the piezoelectric assembly.
A transducer assembly for a resonating surface, the transducer assembly comprising:
- a housing having an interior portion and an exterior portion;
- a spacer having a proximal end and a distal end, wherein the proximal end is configured to be connected to the housing and the distal end is configured to be connected to the resonating surface;
- and
- a piezoelectric assembly disposed between the spacer and the housing, wherein the piezoelectric assembly is configured to be attached about the proximal end of the spacer and spaced apart from the resonating surface.
A method, comprising:
- attaching a transducer assembly to a resonating surface of a vehicle, the transducer assembly comprising a piezoelectric assembly spaced apart from the resonating surface;
- and
- receiving, by the piezoelectric assembly, a kinetic vibration resonating from the resonating surface;
- and
- generating, by the piezoelectric assembly, an electric output signal associated with the kinetic vibration.
