Abstract

The invention relates to the technical field of physics teaching aids, and in particular relates to a vibration sounding instrument which is composed of a spring piece, a sounding gear, a support, a motor, a speed adjusting knob, a power supply switch, a resonance box, a battery box, a frequency indication lamp and a contact switch. The vibration sounding instrument is characterized in that the spring piece, the contact switch, the support, the speed adjusting knob, the power supply switch and the frequency indication lamp are fixedly arranged on an upper panel of the resonance box. The sounding gear is fixed on a motor shaft. The motor is fixedly arranged on the support. The spring piece contacts the sounding gear. The spring piece, the motor, a speed adjusting resistor, the power supply switch, the battery box, the frequency indication lamp, a current limiting resistor and the contact switch are electrically connected. According to the invention, through the speed adjusting knob, the rotation speed of the motor is changed, and the tone is changed; the obvious change of the tone can be heard; through the change of the stroboscopic speed of the frequency indication lamp, a phenomenon is intuitive; and an abstract sound feature is shown through an experiment, which fills the gap of relevant experiment instruments.

Description

technical field [0001] The invention relates to the technical field of physical teaching aids, in particular to a vibrating and sounding instrument. Background technique [0002] At present, the demonstration experiment that the tone is determined by the frequency generally adopts the method of stirring the steel ruler or the wooden comb with the steel ruler. The phenomenon is not obvious, the intuitiveness is poor, and the experimental effect is not ideal. Contents of the invention [0003] The object of the present invention is to provide a vibrating and sounding instrument aiming at the deficiencies of the above-mentioned prior art. [0004] The present invention solves its technical problem and realizes through the following technical solutions: [0005] A vibrating and sounding instrument is composed of a spring plate, a sounding gear, a bracket, a motor, a speed control knob, a power switch, a resonance box, a battery box, a frequency indicator light and a contact s...
