Description
Technical Field
The invention relates to the technical field of science popularization education, in particular to a device for demonstrating a standing wave phenomenon.
Background
Standing waves are two waves of the same frequency and opposite transmission directions, and form a distributed state along a transmission line, wherein one wave is generally a reflected wave of the other wave. The existing standing wave demonstrating device generally adopts acoustic standing wave to demonstrate. Other forms of presentation devices have not been found suitable for use in science and technology museums for the time being.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a device for demonstrating the standing wave phenomenon, which is suitable for a science and technology museum.
In order to solve the technical problems, the invention adopts the following technical scheme:
the utility model provides a device of demonstration standing wave phenomenon, includes the stage body and establishes vibrating device on the stage body, vibrating device includes 18 motors, motor and vibrating arm link to each other and install the one end of stage body, the vibrating arm extends to the other end of stage body the cover has a plurality of foaming ball on the vibrating arm.
Preferably, the motor is a DC24V direct current vibration motor.
Compared with the prior art, the invention has the beneficial effects that:
the invention relates to a device for demonstrating standing wave phenomenon, which adopts a foaming ball to vibrate on a vibrating rod to generate vibration waves to demonstrate the standing wave phenomenon, so that audiences can intuitively feel the knowledge related to the standing wave phenomenon.
Drawings
FIG. 1 is a schematic front view of the present invention;
FIG. 2 is a schematic top view of the present invention;
FIG. 3 is a schematic side view of the present invention.
Detailed Description
Referring to the attached drawings 1-3, the device for demonstrating standing wave phenomenon comprises a table body 1 and a vibration device arranged on the table body 1, wherein the vibration device comprises 18 motors 2, the motors 2 are connected with a vibration rod 3 and are arranged at one end of the table body 1, the vibration rod 3 extends to the other end of the table body 1, and a plurality of foaming balls 4 are sleeved on the vibration rod 3.
Preferably, the motor is a DC24V direct current vibration motor.
The operation process is as follows: switch on, motor 2 begins work, and motor 2 drives vibrating arm 3 and begins the vibration, produces the standing wave on the vibrating arm 3, and a plurality of foaming balls 4 on the vibrating arm 3 follow vibrating arm 3's vibration and begin the up-and-down motion, and foaming ball 4 on vibrating arm 3 is static vibration often under the different vibration frequency of shock dynamo often, and the collision back is separately immediately between the foaming ball 4, adjusts motor 2's rotational speed, and foaming ball 4 static position on vibrating arm 3 also can change. The vibration of the motor 2 is used as an exciting force to drive the vibrating rod 3 to vibrate, a certain vibration waveform is formed in the vibrating rod 3, and some foaming balls 4 can stay at wave crests or wave troughs; changing the rotation speed of the motor 2, i.e., changing the frequency of the exciting force, changes the waveform of the standing wave in the vibratory rod 3. The viewer observes the vibration process of the foam ball 4 to feel and understand what is the standing wave phenomenon.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention in any way, so that any person skilled in the art can make changes or modifications to the equivalent embodiments using the above disclosure. However, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present invention are still within the protection scope of the present invention, unless they depart from the technical spirit of the present invention.
