摘要： The present disclosure indicates a bubble generating device (1) that is attached to a liquid tank and generates, by vibration, fine bubbles in a liquid in the liquid tank. The bubble generating device (1) includes a vibration plate (2), a first cylindrical body (31), a spring (32), a second cylindrical body (33), and a piezoelectric element (4). The vibration plate (2) has a plurality of pores, is in contact with a liquid on one surface, and is in contact with a gas on another surface. The first cylindrical body (31) holds, at one end, the vibration plate (2). The spring (32) having a plate shape supports another end of the first cylindrical body (31). The second cylindrical body (33) supports, at one end, a position of the spring (32) outside a position where the first cylindrical body (31) is supported. The piezoelectric element (4) is provided at another end of the second cylindrical body (33) and vibrates the second cylindrical body (33).

摘要： A driving unit (81) applies a drive signal to a piezoelectric film (20). The diaphragm (40) transitions to a state in FIG 5(A) or a state in FIG 5(C) based on a state in FIG 5(B) according to an amplitude of the drive signal, and vibrates along a front surface direction and a back surface direction. Thus, vibrations corresponding to the drive signal transmit to a touch panel (50) via the diaphragm (40), and transmit to a user who has touched the touch panel (50). The diaphragm (40) receives a stationary bending stress in a non-operation state, and therefore a force applied to the diaphragm (40) when the piezoelectric film (20) and an exciter film (30) stretch is the same direction as that of the bending stress. Consequently, the tactile sense presentation device (10) can efficiently vibrate the diaphragm (40), and transmit vibrations which are strong to some degree even when a piezoelectric film is used.

摘要： A vibration structure (1) includes a piezoelectric film (12) that is deformed in a plane direction as voltage is applied, a frame-shaped member (10) connected to the piezoelectric film (12), a vibration portion (14) that is supported by the frame-shaped member (10) via a support portion (13) and vibrates in the plane direction as the piezoelectric film (12) is deformed, and a connection member (15) that connects the piezoelectric film (12), the vibration portion (14), and the frame-shaped member (10). Of the connection members (15), a first connection member (151) for connecting the vibration portion (14) and the piezoelectric film (12) is disposed between the center of gravity of the vibration portion (14) and a second connection member (152) for connecting the frame-shaped member (10) and the piezoelectric film (12).

摘要： A vibrating device and a tactile sense presenting device can reliably vibrate a diaphragm in a thickness direction from a flat state of the diaphragm. A vibrating device (20) includes: a diaphragm (21) which warps in a thickness direction; a piezoelectric film (22) which is connected to the diaphragm (21) and is stretched in a direction crossing the diaphragm (21) from a connection position with the diaphragm (21); and a spacer (23) which secures an interval between the diaphragm (21) and the piezoelectric film (22) at a position apart from the connection position of the diaphragm (21) and the piezoelectric film (22).
