发明名称 ACOUSTIC GENERATOR, ACOUSTIC GENERATION DEVICE, AND ELECTRONIC APPARATUS
摘要 [Problem] To provide an acoustic generator, wherein it is possible to improve sound quality and to inhibit the frequency fluctuation of a sound pressure as much as possible by reducing the difference between the oscillation peak and dip in the frequency characteristics of the sound pressure. To also provide an acoustic generation device and an electronic apparatus. [Solution] An acoustic generator of one mode is provided with a vibrating body, an exciter disposed on the vibrating body, a cover part covering the exciter, and a damping material integrated with the vibrating body, the exciter, and the cover part. The damping material is formed from a material that has a lower elastic modulus than the cover part.
