摘要： A sound generator 30 includes a piezoelectric element 1, a vibrating body 3a, a reflection member 81, a reflection member 82, an opening 21, and an opening 22. The vibrating body 3a vibrates due to vibration of the piezoelectric element 1 and generates a sound. The reflection member 81 is disposed in a first direction from the vibrating body 3a so as to be inclined with respect to the vibrating body 3a. The reflection member 82 is disposed in a second direction, which is opposite to the first direction, from the vibrating body 3a so as to face the reflection member 81 with the vibrating body 3a therebetween and so as to be inclined with respect to the vibrating body 3a. The opening 21 faces in a third direction. The opening 22 faces in a fourth direction, which is different from the third direction.

摘要： An acoustic generator according to one embodiment includes a piezoelectric element (exciter), a vibrating portion, and a plurality of dampers. The piezoelectric element receives an input of an electrical signal and is caused to vibrate. The piezoelectric element is mounted on the vibrating portion, and the vibrating portion is caused to vibrate by the vibration of the piezoelectric element. The dampers are integrated with the vibrating portion. The dampers are asymmetrically provided with respect to an axis of symmetry of a shape delineated by the outline of the vibrating portion, in a plan view of the vibrating portion from a side on which the piezoelectric element is mounted.

摘要： The problem is to reduce variations of sound pressure in the sound pressure frequency characteristics. To solve the problem, an acoustic generator includes a film that is a supporting plate; a frame member that is provided on the outer circumference of the film; a piezoelectric element that is provided on the film within a frame of the frame member; and a resin layer that is provided on the film within the frame of the frame member, and the resin layer including an air bubble. By the air bubble, a decrease in the sound pressure is prevented, peaks and dips in the frequency characteristics of sound pressure are reduced, and high-quality sounds are generated.
