Embodiment Construction

[0034] figure 1 is a perspective view of vibration structure 1, figure 2 It is an exploded perspective view. image 3 (A) is a top view of vibration structure 1, image 3 (B) is AA cross-sectional view.

[0035] The vibration structure 1 of the present embodiment includes a frame-shaped member 10 , a piezoelectric film 12 , a support portion 13 , a vibration portion 14 , and a connection member 15 .

[0036] The shape of the frame member 10 in plan view is rectangular. The frame member 10 has a rectangular opening 11 . However, in this example, the openings 11 are composed of two first openings 11A arranged at both ends in the longitudinal direction of the frame member 10 and two second openings 11B arranged at both ends in the short direction. The first opening 11A has a rectangular shape that is long along the short-side direction of the frame-shaped member 10 . The second opening 11B is a rectangular opening that is long along the longitudinal direction of the frame-...

Abstract

The vibration structure includes: a diaphragm (12), a frame member (10), a vibrating portion (14), a support portion (13), and a connecting member (15). The diaphragm (12) is deformed in the plane direction by applying a voltage. The frame-shaped member (10) is connected to the diaphragm (12) and has an opening. The vibrating part (14) is connected to the above-mentioned diaphragm (12) in an area smaller than the area of ​​the above-mentioned opening in plan view, and the vibrating part (14) is vibrated in the above-mentioned planar direction by the deformation of the above-mentioned diaphragm (12) in the above-mentioned planar direction . The supporting part (13) connects the vibrating part (14) to the frame-shaped member (10) and supports the vibrating part (14) on the frame-shaped member (10). A connecting member (15) connects the diaphragm (12), the vibrating portion (14) and the frame-shaped member (10).

Description

technical field [0001] The invention relates to a vibrating structure, a vibrating device and a tactile prompting device for generating vibrations. Background technique [0002] In recent years, a touch panel has been proposed that transmits vibration when the user presses the touch panel, thereby giving tactile feedback so that the touch panel can feel "pressed". [0003] For example, Patent Document 1 discloses a configuration in which a vibration motor is arranged at an end portion of a touch panel to vibrate the entire touch panel with a substantially uniform vibration amount. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2012-137971 [0005] However, since the vibration motor has a coil, it becomes thicker. Contents of the invention [0006] Therefore, an object of the present invention is to provide a vibrating structure, a vibrating device, and a tactile feedback device thinner than those using a vibrating motor. [0007] The vibration structure inclu...
