| description | The invention discloses a resonance demonstration apparatus. The resonance demonstration apparatus includes a support and a magnetoelectric instrument fixed on the support, wherein a swing ball is suspended on a swing pointer of the magnetoelectric instrument; a swing ball vibration frequency detector is arranged just below the normal of the magnetoelectric instrument; a signal detection module, the swing ball vibration frequency detector and a display unit are in communication connection with a controller; circumferential scales are drawn on the support; during the working process, two ends of the magnetoelectric instrument access alternating current electric signals which are symmetrical in anode and cathode; and the signal detection module is used for detecting the alternating current electric signals, which are symmetrical in anode and cathode, accessing the magnetoelectric instrument. The resonance demonstration apparatus can quantitatively analyze the relation between a driving period or a driving frequ |
