Description

Technical Field

[0001] The utility model belongs to the technical field of teaching tools, and particularly relates to a water cup water filling device. Background Art

[0002] The principle of playing music with a water cup mainly involves the generation of sound and the influence of the size of the resonance cavity on the pitch. Sound is generated by the vibration of objects. Different objects have different vibration frequencies and produce different pitches. When the water cup is knocked or rubbed, the wall of the cup will vibrate, thus producing sound. Different amounts of water in the water cup will change the length of the air column in the cup, thus affecting the frequency of vibration, that is, the pitch. Specifically, the less water, the shorter the air column, the higher the vibration frequency, and the higher the pitch; on the contrary, the more water, the longer the air column, the lower the vibration frequency, and the lower the pitch.

[0003] Most of the existing methods adopt the method of controlling the water content in the cup by having the teacher pour water himself, and then judging whether there is too much or too little water by knocking. It takes multiple adjustments to accurately knock out the corresponding tone, which is quite troublesome. Summary of the invention
