Patent ID: 8218214

Claim:
A vibration-actuated micro mirror device, comprising: a substrate configured with a reflection mirror and a swinging frame; and a vibration part, configured with a fixing plate, a first vibration structure and a second vibration structure in a manner that the first and the second vibration structures are disposed respectively on the fixing plate while being coupled to the substrate; wherein, the first vibration structure has ability to receive a first driving signal so as to generate a first complex wave formed by a first wave signal and a second wave signal; and the second vibration structure has ability to receive a second driving signal to generate a second complex wave formed by a third wave signal and a fourth wave signal; wherein, the first wave signal and the third wave signal are formed with a same first frequency while the second wave signal and the fourth wave signal are formed with a same second frequency, and the first and the second complex waves actuate the substrate for enabling the swinging frame to rotate about a first axis while enabling the reflection mirror to rotate about a second axis.
