Abstract | According to one embodiment of the present invention, a camera actuator includes: a housing; a prism unit disposed in the housing; and a drive unit disposed in the housing so as to tilt the prism unit. The drive unit comprises: a first piezoelectric device disposed in a region overlapping in a first direction with respect to the center of the prism unit; and a second piezoelectric device disposed in a region overlapping in a second direction, different from the first direction, with respect to the center of the prism unit. The prism unit is provided so as to be tiltable in the second direction by means of the first piezoelectric device, and is provided so as to be tiltable in the first direction by means of the second piezoelectric device. Therefore, it is possible to effectively control vibration caused by handshake.
실시 예에 따른 카메라 액추에이터는, 하우징; 상기 하우징 내에 배치되는 프리즘부; 및 상기 하우징 내에 배치되며 상기 프리즘부를 틸팅하는 구동부;를 포함하고, 상기 구동부는, 상기 프리즘부의 중심을 기준으로 제1 방향으로 중첩되는 영역에 배치되는 제1 압전소자; 및 상기 프리즘부의 중심을 기준으로 상기 제1 방향과 다른 제2 방향으로 중첩되는 영역에 배치되는 제2 압전소자를 포함하고, 상기 프리즘부는 상기 제1 압전소자에 의해 상기 제2 방향으로 틸트 가능하게 제공되고, 상기 제2 압전소자에 의해 상기 제1 방향으로 틸트 가능하게 제공된다. |
