A synthetic jet equipment is provided, including a base, a frame fixed to the base, a first member, a pump diaphragm, a second member, and a valve diaphragm. The pump diaphragm connects the first member to the frame, and the valve diaphragm connects the second member to the frame. The base, the frame, the first member, the pump diaphragm, the second member, and the valve diaphragm define a chamber forming an intake and an outlet. When the first member moves in a first direction, the second member moves in a second direction opposite to the first direction and the external air flows into the chamber through the inlet. When the first member moves in the second direction, the second member moves in the first direction, such that the air is exhausted from the chamber through the outlet.

The present disclosure provides a swinging device having a swinging mechanism disposed on an energy provider, wherein volume and shape of the swinging mechanism and a distance between the swinging mechanism and the energy provider are adjusted so as to control the ratio of the distance and a characteristic value corresponding to the swinging mechanism in a specific range such that the swinging mechanism is capable of resonating with respect to the rotation of the energy provider. The swinging mechanism is capable of detecting the rotating frequency of the energy provider as well as combining with a display unit which is capable of displaying information with respect to the rotating status or displaying image patterns controlled according to the rotating status.

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.
