发明名称 Piezoelectric device and electronic apparatus
摘要 A piezoelectric device includes a vibrator, a piezoelectric drive unit, and a first piezoelectric detector. The vibrator includes a first surface, a first groove formed along a first axis direction, and a second groove formed to be parallel to the first groove. The piezoelectric drive unit includes a first electrode pair provided in the first groove and opposed to each other in a second axis direction orthogonal to the first axis direction and parallel to the first surface, and a first piezoelectric body provided between the first electrode pair, and is capable of vibrating the vibrator. The first piezoelectric detector includes a second electrode pair provided in the second groove and opposed to each other in the second axis direction, and a second piezoelectric body provided between the second electrode pair, and is capable of detecting a vibration of the vibrator.

主权项 1. A piezoelectric device, comprising: a vibrator including a first surface,a first groove that is formed along a first axis direction in the first surface, anda second groove that is formed in the first surface to be parallel to the first groove; a piezoelectric drive unit including a first electrode pair that are provided in the first groove and opposed to each other in a second axis direction that is orthogonal to the first axis direction and parallel to the first surface, anda first piezoelectric body that is provided between the first electrode pair, the piezoelectric drive unit being configured to be capable of vibrating the vibrator in a plane parallel to the first surface due to voltage application between the first electrode pair; and a first piezoelectric detector including a second electrode pair that are provided in the second groove and opposed to each other in the second axis direction, anda second piezoelectric body that is provided between the second electrode pair, the first piezoelectric detector being configured to be capable of detecting a vibration of the vibrator in the plane parallel to the first surface.
