Title:
圧電アクチュエータ
Document Type and Number:
Japanese Patent JP6585640
Kind Code:
B2
Abstract:
A piezoelectric actuator (13) includes a suspension plate (130), an outer frame (131), at least one bracket (132) and a piezoelectric ceramic plate (133). The suspension plate (130) is a square structure. The length of the suspension plate (130) is in a range between 7.5mm and 12mm, and the suspension plate (130) is permitted to undergo a curvy vibration from a middle portion (130d) to a periphery portion (130e). The outer frame (131) is arranged around the suspension plate (130). The at least one bracket (132) is connected between the suspension plate (130) and the outer frame (131) for elastically supporting the suspension plate (130). The piezoelectric ceramic plate (133) is a square structure and has a length not larger than a length of the suspension plate (130). The piezoelectric ceramic plate (133) is attached on a first surface (130b) of the suspension plate (130). When a voltage is applied to the piezoelectric ceramic plate (133), the suspension plate (130) is driven to undergo the curvy vibration.
