Exhibit size: 400×280×350mm
Function overview: Demonstrate the principle of sound resonance. When one of the two drums is struck, the small ball hanging on the opposite drum will jump (that is, the drum surface vibrates). When the sound is heard, it will cause other adjacent objects to vibrate together, that is, sound waves. resonance.
Instructions for operation: Play the drum on the side of the drum, and observe the vibration of the small ball hanging on the other drum surface.
Scientific principle and functional description: Resonance refers to two objects with the same vibration frequency, when one of them vibrates, the other object is excited by the outside world to produce forced vibration. If the frequency of the external excitation is close to the system frequency, the amplitude of the forced vibration can reach very large values, which is called resonance. An important condition for resonance is elasticity, when an object is affected by an external frequency, its frequency should be the same or substantially similar to the external frequency.
