    Abstract: A method includes preparing a first substrate member in which a cavity is formed. Moreover, the method includes preparing a magnetic member having a plurality of magnetic pieces. The magnetic member is placed in the cavity, and the second substrate member is placed on the first substrate member to close the cavity. The cavity is defined at least in part by a pair of wall surfaces facing each other in a lateral direction and opens upward in an up-down direction perpendicular to the lateral direction. The magnetic pieces are coupled with each other by positioning members so as to be arranged at regular intervals in a predetermined direction. The placing of the magnetic member in the cavity is carried out so that the predetermined direction coincides with the lateral direction or a front-rear direction perpendicular to both of the lateral direction and the up-down direction.

  • 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.
