Description

Technical Field

[0001] The utility model belongs to the technical field of teaching tools, and particularly relates to a water cup sound-generating 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] Therefore, by changing the amount of water in the cup, the frequency of the vibration of the cup wall can be adjusted to play different music.

[0004] The existing teaching methods can only be demonstrated simply by using cups and sticks, which cannot leave a deep impression on students. Summary of the invention

DETAILED DESCRIPTION

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] like Figure 1-Figure 3As shown, the water cup sound-making device comprises a support base 1, the support base 1 is provided with a make-way groove 2, a plurality of pressing devices 3 for people to press are arranged in the make-way groove 2, a plurality of knocking devices 4 for knocking the water cup are also arranged above the support base 1, the pressing device 3 comprises a pressing plate 5, a support block 6 and a return spring 7, the middle part of the pressing plate 5 is rotatably connected to the support block 6, the return spring 7 is arranged at one end of the pressing plate 5 away from the knocking device 4, the pressing plate 5 is used for people to press down on one end close to the return spring 7, and drive the other end to rise and control the knocking device 4.

[0022] To further explain, the knocking device 4 includes a support base 8 and a knocking stick 9, which is rotatably connected to the support base 8. One end of the knocking stick 9 is arranged above the pressing plate 5. The knocking stick 9 acts as a lever, one end rises and the other end falls. When the operator presses the pressing device 3, the pressing device 3 will raise that side of the knocking stick 9, so that the other end of the knocking stick 9 falls and knocks the cup to produce a sound.

[0023] To elaborate further, a receiving groove 10 and a counterweight 11 are provided at one end of the knocking stick 9 close to the pressing plate 5. This arrangement is used to ensure that in the absence of external force, the end of the knocking stick 9 close to the pressing plate 5 is at the bottom, and different counterweights 11 can be selected to achieve different pressing feels.

[0024] To elaborate further, the support base 1 is provided with a support plate 12 for placing a cup, which is used to facilitate the positioning of the cup and prevent the cup from being too far away from the knocking stick 9.
