ACOUSTIC GENERATOR, ACOUSTIC GENERATING APPARATUS, AND ELECTRONIC APPARATUS |
摘要 |
An acoustic generator according to an embodiment includes a film-shaped vibrating body, a flame, and an exciter. The frame is configured to fix at least both ends of the vibrating body in a second direction perpendicular to a first direction that is a thickness direction of the vibrating body. The exciter is disposed on the vibrating body, and is configured to vibrate itself to vibrate the vibrating body. The vibrating body has a value of an average coefficient of linear expansion during a temperature change from 90° C. to 40° C. set to be not less than a value of the average coefficient of linear expansion of the vibrating body during a temperature change from 40° C. to 90° C., and set to be not less than a value of an average coefficient of linear expansion of the flame during a temperature change from 90° C. to 40° C. |

1. An acoustic generator, comprising:
a film-shaped vibrating body; a frame configured to fix at least both ends of the vibrating body in a second direction perpendicular to a first direction that is a thickness direction of the vibrating body; and an exciter disposed on the vibrating body, and configured to vibrate itself to vibrate the vibrating body, wherein the vibrating body has a value of an average coefficient of linear expansion during a temperature change from 90° C. to 40° C. set to be not less than a value of the average coefficient of linear expansion of the vibrating body during a temperature change from 40° C. to 90° C., and set to be not less than a value of an average coefficient of linear expansion of the frame during a temperature change from 90° C. to 40° C. |
