| 发明名称 | Acoustic generator | ||
| 摘要 | Provided is an acoustic generator which has a high sound pressure at ultrahigh frequencies and which can suppress occurrence of large peak dips. An acoustic generator includes a film, a frame member disposed on an outer peripheral edge of the film, a piezoelectric element disposed on the film and inside the frame member, and a resin layer filled inside the frame member so as to cover the piezoelectric element. | ||

| 主权项 | 1. An acoustic generator, comprising: a film including a top surface and a bottom surface; a frame member disposed on an outer peripheral edge of the film; a piezoelectric element disposed on the top surface and inside the frame member; and a resin layer disposed inside the frame member so as to cover the piezoelectric element and a region of the film between the piezoelectric element and the frame member, wherein an interior of the frame member has a rectangular shape, and the acoustic generator includes portions which differ from one another in height from the film to a surface of the resin layer so as to be asymmetric with respect to a center in a longitudinal direction of the interior of the frame member. | ||
