Title:
VIBRATION UNIT
Document Type and Number:
WIPO Patent Application WO/2019/059101
Kind Code:
A1
Abstract:
In this vibration unit 10, a piezoelectric element 32 is disposed within the inner space S of a through-hole 42 to enable a second case member 42 to be disposed close to a first case member 20. As a result, the vibration unit 10 is thinned, i.e. the height H of the vibration unit 10 is reduced. Thus, the vibration unit 10 is thinned to make the vibration unit 10 compact.
