  • Device generating sound
    Patent number: 9743166
    Abstract: In the present invention, a device is provided with a main surface member, a piezoelectric body plate, a first support part, and a housing. The main surface member is used as a vibration plate. The piezoelectric body plate vibrates according to an electric signal. The first support part supports the piezoelectric body plate. The housing has a second support part that supports the main surface member and extends in a prescribed direction that intersects the main surface member. The first support part is secured to the second support so that the second support part vibrates in the prescribed direction according to the vibration of the piezoelectric body plate. The vibration of the piezoelectric body plate is transmitted to the main surface member via the first support part and the second support part, and due to this the main surface member vibrates to generate a sound.
