| titleOfInvention | Electroacoustic transducer |
| abstract | The invention provides an electroacoustic conversion device which can improve the sound characteristic. An electroacoustic transducer according to an embodiment of the present invention includes a casing and a piezoelectric sounding body. The piezoelectric sounding body includes a 1 st vibrating plate and a piezoelectric element, the 1 st vibrating plate has a peripheral edge portion directly or indirectly supported by the case, the piezoelectric element is disposed on at least one surface of the 1 st vibrating plate, and the piezoelectric sounding body is configured such that rigidity is asymmetric with respect to a central axis of the 1 st vibrating plate. |
