The vibration device includes a translucent body, a vibration body that vibrates the translucent body, a drive unit that drives the vibration body, and a control unit that controls the drive unit. The control unit determines a high-frequency-band resonance frequency of the vibrating body on the basis of a state of the drive unit obtained by changing a drive frequency of the drive unit within a high-frequency band of 100 kHz or more, and estimates the temperature of the light-transmitting body on the basis of the determined high-frequency-band resonance frequency.
振动装置具备透光体、使透光体振动的振动体、驱动振动体的驱动部以及控制驱动部的控制部。控制部基于通过使驱动部的驱动频率在100kHz以上的高频带内变化所得到的驱动部的状态来决定振动体的高频带共振频率,基于所决定出的高频带共振频率来估计透光体的温度。
