PIEZOELECTRIC SOUNDING BODY AND ELECTROACOUSTIC CONVERTER |
摘要 |
PROBLEM TO BE SOLVED: To provide a piezoelectric sounding body capable of preventing an external electrode of a piezoelectric element from being short-circuited.SOLUTION: A piezoelectric sounding body includes: a piezoelectric element; and a diaphragm. The piezoelectric element includes: an element assembly having a mounting surface; and first and second terminal parts which are formed on the mounting surface and separated from each other. The diaphragm includes: a conductive body part which is connected to the piezoelectric element and has the main surface opposite to the mounting surface; and a first bottomed or non-bottomed pore which is formed in a region opposite to the first terminal part of the main surface and forms a space between the body part and the first terminal part.SELECTED DRAWING: Figure 2 |
