Science Behind It
The system that produces vibrations can vibrate at its natural frequency after the object leaves the equilibrium position under the action of external force, without the need for external force. This type of vibration that is not under the action of external force is called free vibration. Ideally, free vibration is called undamped free vibration source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. The period during free vibration is called the natural period, and the frequency during free vibration is called the natural frequency. They are determined by the conditions of the vibration system itself and are independent of the amplitude
The vibration of a oscillator under the continuous action of periodic external forces is called forced vibration. In practical terms, it refers to all sinusoidal harmonic vibrations induced by periodic stimuli. The frequency at which vibrations are periodically stimulated is called the stimulation frequency. There are also stimuli with multiple frequencies. source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. Reminder: Stimulus is also studied through a random process of random vibration.
Under regular stimulation, a system produces two types of vibrations simultaneously:
Free vibration (one or more natural frequencies), with its magnitude defined by the initial state condition and damping occurring per unit vibration time;
Narrowly defined, a forced vibration with a constant amplitude stimulus frequency. The relationship between the stimulation frequency (or one of multiple) and the natural frequency (or one of multiple), as well as the damping of the vibration system, can be quantified through an amplification function.
Exhibition items description
Exhibit items are composed of booth, fish washing and disinfected weakly alkaline resonance water. When rubbing fish washing ears with hands, the surrounding wall of the fish washing will produce symmetrical vibration, and the water in the vagueness will produce corresponding harmonic vibration, forming beautiful spray and splashed water drops. At the same time, the regular cylindrical copper plate on the fish washing surface will vibrate and make a buzzing sound. source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. It is important to note that spraying water converts invisible vibrations into visible ones, which is crucial for understanding and studying waves.

How to Operate
Participants come to the exhibition items and rub the fish with their hands to wash their ears, learning about the forced resonance of the container.
