摘要:
A swinging apparatus comprising an energy provider and a swinging mechanism disposed thereon. By means of adjusting the size and shape of the swinging mechanism and adjusting a distance between the swinging mechanism and the energy provider so as to control the ratio of the distance between the swinging mechanism and the energy provider to a characteristic value corresponding to the swing mechanism in a range between 4 and 0.25, the swinging frequency of the swinging mechanism may be adjusted automatically to comply with the variation of the motion frequency of the energy provider. The present invention further provides an energy harvester to work with the swinging apparatus and a coil to generate an induced current for power generation during the swing of the swing mechanism. In the present invention, the natural frequency of the swing mechanism may be adjusted according to the rotational velocity of the energy provider.

The present invention provides a vibration-actuated micro mirror device comprising a substrate having a swinging frame and a reflection mirror, and a vibration part having a first and a second vibration structures coupled to the substrate, wherein the first vibration structure is driven to generate a first complex wave formed by a first and a second wave signals while the second vibration structure is driven to generate a second complex wave formed by a third and a fourth wave signals, and the first and the third wave signals are formed with the same frequency and phase while the second and the fourth wave signals are formed with the same frequency but opposite phases. The first and the second complex waves actuate the substrate such that the swinging frame is rotated about a first axis while the reflection mirror is rotated about a second axis.

A vibration-actuated micro mirror device comprises a substrate, a swinging frame, a reflection mirror, and a vibration part. The swinging frame is rotatably arranged within a first accommodating space formed on the substrate. The reflection mirror is rotatably arranged within a second accommodating space formed on the swinging frame. The vibration part further comprises a plate coupled to the substrate, and a first and a second vibration structures. The first and the second vibration structures are coupled to the plate and are spaced a distance away from each other, wherein the first vibration structure receives a first driving signal having a first frequency and the second vibration structure receives a second driving signal having a second frequency smaller than the first frequency, thereby enabling the swinging frame to rotate about the first axis while enabling the reflection mirror to rotate about the second axis.

An ultrasonic linear motor includes a substrate; a vibrator disposed on the substrate having an oblique or curved face at two sides thereof; and a slider having clamping portions at two sides thereof for correspondingly contacting with the two side faces of the vibrator and the substrate surfaces, wherein the vibrator is for generating a driving force to the slider while connecting with a power supply, such that the clamping portions of the slider slides with respect to the two side surfaces of the vibrator and with respect to the substrate surface, thereby generating a linear translation. The present invention adopts a simple structure having few elements that enables easy manufacturing and integration with other elements, thus reducing manufacturing cost.
