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.
