Abstract
A transducer device having a configuration capable of expanding the utilization is provided. A transducer device includes a transducer element, elastic bodies sandwiching the transducer element from two sides and having an elastic modulus smaller than that of the transducer element in a sandwiching direction, a case including an accommodating part for accommodating a transducer unit and having an opening, and an elastic plate member including a support part supported by the case, a facing surface part positioned at the opening of the case and facing the transducer unit, and an elastic deformation part connecting the support part and the facing surface part.
Claims20
A transducer device comprising:
- a transducer element formed by laminating a first electrode, one of a dielectric body or a piezoelectric body, and a second electrode in a predetermined reference direction;
- elastic bodies sandwiching the transducer element from two sides in a sandwiching direction which is at least one of a first sandwiching direction which is a direction coincident with the reference direction and a second sandwiching direction which is a direction perpendicular to the reference direction, and having an elastic modulus smaller than that of the transducer element in the sandwiching direction;
- a case including an accommodating part which accommodates a transducer unit having the transducer element and the elastic bodies, and an opening in at least one of the sandwiching direction of the transducer unit and a direction perpendicular to the sandwiching direction thereof;
- and
- an elastic plate member including a support part supported by the case, a facing surface part positioned at the opening of the case and facing the transducer unit, and an elastic deformation part connecting the support part and the facing surface part,
- wherein the facing surface part
- functions as an input/output member by moving relative to the case,
- functions as an output member which transmits vibration of the transducer element to an outside via the elastic bodies when the transducer element functions as an actuator, and
- functions as an input member which transmits vibration from the outside to the transducer element via the elastic bodies when the transducer element functions as a sensor.
