ACOUSTIC GENERATOR, ACOUSTIC GENERATION DEVICE, AND ELECTRONIC DEVICE |
| 摘要 |
An acoustic generator according to an aspect of an embodiment includes a piezoelectric element (exciter), a vibrating body. The piezoelectric element receives an input of an electrical signal and is caused to vibrate. The piezoelectric element is mounted on the vibrating body, and the vibrating body is caused to vibrate by the vibration of the piezoelectric element. The acoustic generator includes at least one pair of two adjacent portions with different stiffnesses in a plan view, and has at least one damper provided contacting with both of the two adjacent portions. |
