The power of a resonator lies mainly in its ability to emit waves of all frequencies. These waves of different frequencies acting on different objects can correspondingly produce a resonance wave, and the resonator has the formation of a circular through hole insulation board, through the hole in the surrounding part of the insulation board above or through the inner wall of the hole formed a circular wire. Additionally, the side face of the insulation board is provided with a first electrode connected with one end of the wire, and a second electrode connected with another end.
