摘要： In a vibration device, an operation unit has an operation surface operated by a user. A plurality of piezoelectric elements are disposed so as to overlap the operation surface when viewed from the direction orthogonal to the operation surface. The plurality of piezoelectric elements are disposed at mutually different positions in the direction along the operation surface. A control unit is arranged to control the plurality of piezoelectric elements. The control unit is arranged to vibrate the piezoelectric element corresponding to a first position on the operation surface where an operation is performed at a first frequency and vibrates the piezoelectric element corresponding to a second position on the operation surface different from the first position among the plurality of piezoelectric elements at a second frequency, in response to the operation of the operation surface. The second frequency is a frequency in the audible range.

摘要： In an acoustic device, the housing includes a main body portion and a rib portion. The main body portion includes a vibrating portion and a plurality of support portions. The rib portion is connected to the main body portion. The rib portion extends in a third direction between a pair of the support portions facing each other and separated from each other in the third direction intersecting a second direction, when viewed from the second direction along a vibrating surface. A hollow region is defined by the vibrating portion and the plurality of support portions. The above opening is defined by the rib portion and the main body portion and communicates with the hollow region. The rib portion covers the middle of the hollow region when viewed from the second direction.

摘要： Provided is a piezoelectric module capable of attempting further miniaturization. In the piezoelectric module, a resonance point is excluded from a frequency band of a transmitted signal to avoid shortening of a signal transmission distance, thereby attempting improvement in stability of communication. In addition, since a resonance space is not provided, further miniaturization may be easily attempted.
