    摘要： An acoustic generator includes a vibration body; a first exciter and a second exciter which are disposed on the vibration body; a first damping material disposed on the vibration body and having a first portion which overlaps the first exciter; and a second damping material disposed on the vibration body and having a second portion which overlaps the second exciter. The first damping material is disposed so as to straddle at least a portion of a first segment which is a portion of a contour of the first exciter which portion does not face the second exciter, and the second damping material is disposed so as to straddle at least a portion of a second segment which is a portion of a contour of the second exciter which portion does not face the first exciter.

    摘要： There are provided a piezoelectric element capable of implementing an acoustic generator having excellent characteristics and a simple structure, and an acoustic generator, an acoustic generation device, and an electronic apparatus using the same. A piezoelectric element includes a piezoelectric layer; a first conductor; a second conductor; a third conductor; a fourth conductor; a fifth conductor; and a sixth conductor, and includes a first portion, a second portion, and a third portion. The first portion is a portion where the first conductor and the second conductor face each other, and the second portion is a portion where the third conductor and the fourth conductor face each other. The third portion is a portion where the fifth conductor and the sixth conductor do not face each other, the third portion being located between the first portion and the second portion.

    摘要： Provided are a sound generator and an electronic apparatus using the same. The sound generator includes a vibrating body, an exciter that is attached to the vibrating body and bends to vibrate the vibrating body in the thickness direction of the vibrating body by vibrating the exciter itself, an enclosure that is joined to the vibrating body and forms a first space enclosed together with the vibrating body, and a duct that connects between the first space and the external space. A spacing between the vibrating body and the surface of the enclosure facing the vibrating body is smaller than ½ of the length of the wavelength of resonance having the lowest frequency in the bending vibration of the vibrating body.

    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.
