Description

Technical Field

[0001] The utility model belongs to the technical field of teaching tools, and particularly relates to a water cup playing 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] Most of the existing methods adopt the method of having the teacher pour water to control the water content in the cup, 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 rather troublesome. During teaching, only a simple demonstration can be carried out through cups and sticks, which cannot bring a deep impression to students. Summary of the invention

DETAILED DESCRIPTION

[0027] 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.

[0028] like Figure 1-Figure 8As shown, the water cup playing device comprises a supporting base 16, a water filling device 1 and a plurality of water cups 2. The supporting base 16 is provided with a giving way groove 17, and a plurality of pressing devices 18 for people to press are provided in the giving way groove 17. A plurality of knocking devices 19 for knocking the water cups 2 are also provided above the supporting base 16. The pressing device 18 comprises a pressing plate 20, a supporting block 21 and a return spring 22. The middle part of the pressing plate 20 is rotatably connected to the supporting block 21. The return spring 22 is provided at one end of the pressing plate 20 away from the knocking device 19. The pressing plate 20 is used for people to press down one end close to the return spring 22 to drive the other end to rise and control the knocking device 19. The water filling device 1 is used to fill water into the plurality of water cups 2, and the water cups 2 are provided below the knocking device 19.

[0029] To further explain, the knocking device 19 includes a support base 23 and a knocking stick 24. The knocking stick 24 is rotatably connected to the support base 23. One end of the knocking stick 24 is arranged above the pressing plate 20. The knocking stick 24 acts as a lever. When one end rises, the other end will fall. When the operator presses the pressing device 18, the pressing device 18 will raise that side of the knocking stick 24, so that the other end of the knocking stick 24 will fall and knock on the cup to produce a sound.

[0030] To elaborate further, a receiving groove 25 and a counterweight 26 are provided at one end of the knocking stick 24 close to the pressing plate 20. This arrangement is used to ensure that in the absence of external force, the end of the knocking stick 24 close to the pressing plate 20 is at the bottom, and different counterweights 26 can be selected to achieve different pressing feels.

[0031] To explain in further detail, the water injection device 1 includes a water tank 3 and a water pump 4. Multiple water cups 2 are all provided with a water inlet 5 and a water outlet 6. The height of the water inlet 5 is higher than the water outlet 6. Multiple water cups 2 are connected in sequence, and the water outlets 6 of multiple water cups 2 are lowered in sequence. Before the experiment, the water tank 3 is connected to the water inlet 5 of the water cup 2 with the highest water outlet 6 through a water pipe. When the water level reaches the water outlet 6, the water enters the water inlet 5 of the next cup from the water outlet 6 until the water level in all water cups 2 reaches the water outlet 6. The water content in each cup is different, so that each water cup 2 can emit a corresponding tone, which is convenient for teachers to teach quickly and the tone is accurate.

[0032] To elaborate further, each water inlet 5 is provided with a first connecting column 7, and each water outlet 6 is provided with a second connecting column 8. The first connecting column 7 and the second connecting column 8 are used to facilitate the connection of water pipes. The water pipes can be directly put on the first connecting column 7, which is convenient for installation and disassembly.

[0033] In further detail, a first paving groove 9 is provided above the water inlet 5, and a second paving groove 10 is provided above the water outlet 6. This arrangement is used to stack the water cups 2 for easy transportation and storage.

[0034] To elaborate further, the water tank 3 is provided with a recovery device 11, which is used to connect to the water outlet 6 of the last water cup 2. The recovery device 11 includes a recovery connection column 12 and a sealing cover 13. The sealing cover 13 is used to seal the recovery connection column 12. The recovery connection column 12 and the sealing cover 13 are detachably connected. This setting is used to prevent overflow due to excessive water pumped out by the water pump 4. The excess water will return to the water tank 3 from the recovery device 11. The recovery connection column 12 is used to facilitate the installation and disassembly of the water pipe. The recovery connection column 12 is connected to the inside of the water tank 3, and the recovery connection column 12 is arranged at the upper part of the water tank 3.

[0035] To elaborate further, a mounting groove 14 for installing the water cup 2 is provided on the top of the water tank 3. This setting is used to limit the water cup 2 to facilitate subsequent demonstration operations, and at the same time makes the height of the water cup 2 higher than the water tank 3, so that the recovery device 11 can recover excess water.

[0036] To elaborate further, a switch 15 is provided on the water pump 4 , and the switch 15 is used to control the opening and closing of the water pump 4 . The switch 15 is used to control the opening and closing of the water pump 4 . This setting is used to facilitate the control of the opening and closing of the water pump 4 .

[0037] In further detail, a plurality of suction cups 27 are provided on the bottom surface of the support base 16 and the bottom surface of the water storage tank 3 , and this arrangement is used to increase the stability of the support base 16 and the water storage tank 3 .
