Abstract
The present technology relates to an electroacoustic transducer and an electroacoustic transducer apparatus that are compact, have good characteristics, and can retain their stable shape. The electroacoustic transducer includes: a first sheet including a sheet-like piezoelectric material and having a curved shape; and a second sheet having substantially the same shape as the first sheet and placed on the first sheet in a layered manner. The present technology can be applied to an electroacoustic transducer.

An electroacoustic transducer comprising:
- a first sheet including a sheet-like piezoelectric material and having a curved shape;
- and
- a second sheet having substantially a same shape as the first sheet and placed on the first sheet in a layered manner.
An electroacoustic transducer apparatus comprising:
- a first electroacoustic transducer having:
- a first sheet having a curved shape and including a sheet-like piezoelectric material;
- and a second sheet having substantially a same shape as the first sheet and placed on the first sheet in a layered manner;
- and
- a second electroacoustic transducer having a third sheet including a sheet-like piezoelectric material, having a curved shape, and having an area different from an area of the first sheet of the second sheet.
An electroacoustic transducer apparatus comprising:
- a first electroacoustic transducer having:
