Title:
TRANSDUCER AND VIBRATION PRESENTING DEVICE IN WHICH SAME IS USED
Document Type and Number:
WIPO Patent Application WO/2018/181641
Kind Code:
A1
Abstract:
Provided are a transducer in which it is possible to lessen an adhesive layer while reducing an electrode material, and a vibration presenting device in which said transducer is used. A transducer (1) comprising a first electrode sheet (11) provided with a plurality of first through-holes (11a), a second electrode sheet (12) provided with a plurality of second through-holes (12a), a piezoelectric sheet (13) or dielectric sheet (13) disposed between a first inner surface of the first electrode sheet (11) and a second inner surface of the second electrode sheet (12), a first protective sheet (14) that covers a first outer-surface side of the first electrode sheet (11), and a second protective sheet (15) that covers a second outer-surface side of the second electrode sheet (12). The first protective sheet (14) adheres to the piezoelectric sheet (13) or dielectric sheet (13) via the first through-holes (11a) in the first electrode sheet (11).
