Abstract

The present invention provides a vibration device capable of detecting deformation in a normal direction without hindering vibration. A vibration unit having a vibrator vibrating in a planar direction; and a sensor disposed at least partly around the vibrator in the vibration unit in plan view and detecting a pressing operation in a normal direction.

Description

technical field [0001] The present invention relates to a vibrating device for generating vibrations. Background technique [0002] In recent years, a tactile feedback device has been proposed that transmits vibration when a user performs a pressing operation in an input device such as a touch panel, thereby allowing the user to actually feel that the user has pressed. [0003] For example, Patent Document 1 proposes a tactile feedback device that uses a film 12 to give tactile feedback to a user. In Patent Document 1, the film 12 is deformed in the plane direction by applying a voltage. The vibrating part 14 connected to the membrane 12 vibrates in the planar direction due to expansion and contraction of the membrane 12 . [0004] Patent Document 1: International Publication No. 2019 / 013164 [0005] When the tactile feedback device has a function of detecting a pressing operation, for example, it is necessary to add a pressing sensor for detecting deformation in the norm...
