Title:
PIEZOELECTRIC VIBRATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/043223
Kind Code:
A1
Abstract:
This piezoelectric vibration device is provided with piezoelectric transformers (1A, 1B), a flexible substrate (2), and a case (3). The flexible substrate (2) is provided with: element mounting terminals, to which external electrodes of the piezoelectric transformers (1A, 1B) are connected; and external connecting terminals connected to a wiring board (200). The case (3) has fixing sections (32S) to the wiring board (200), and a ceiling section, and the fixing sections (32S) form a space between the ceiling section and the wiring board (200) in a state of being mounted on the wiring board (200), said space having the piezoelectric transformers (1A, 1B) and the flexible substrate (2) stored therein. The piezoelectric transformers (1A, 1B) are suspended from the ceiling section of the case (3) by means of holding members. Consequently, provided is the piezoelectric vibration device, wherein characteristic deterioration due to displacement of the piezoelectric vibrators and fluctuation of pressing force of the lead terminals is suppressed.
