Title:
TACTILE FEEDBACK UNIT, TACTILE FEEDBACK DEVICE AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/006844
Kind Code:
A1
Abstract:
Disclosed are a tactile feedback unit, a tactile feedback device and an electronic apparatus. The tactile feedback unit comprises a piezoelectric member, a first elastic piece and a second elastic piece, wherein the vertical distance from a first surface to a second surface of the piezoelectric member is a first distance, and the vertical distance from a first side face to a second side face of the piezoelectric member is a second distance, with the first distance being smaller than the second distance; the first elastic piece is connected to the first side face, the second elastic piece is connected to the second side face, a side of the first elastic piece that faces away from the first side face is used for being connected to a fixed member, and a side of the second elastic piece that faces away from the second side face is used for being connected to a movable member; and the piezoelectric member deforms after receiving a driving voltage signal, and drives the first elastic piece and the second elastic piece to elastically deform, such that the movable member displaces relative to the fixed member. The first elastic piece and the second elastic piece are configured to serve as media, the deformation of the piezoelectric member is conducted to the movable member, and a slight deformation of the piezoelectric member can be amplified, such that the tactile feedback effect is good.
