Resonance Drum

Acoustics

★Exhibit Content: Sound Wave Transmission and Resonance ★Interaction: Mechanical Interaction ★Operation: Participants strike the drum with the drumstick and observe the vibration of the other drumhead. ★Exhibit Description: The exhibit mainly consists of two identical drums, a platform, drum stands, and drumsticks. The two identical drums are placed parallel at a certain distance. When either drumhead is struck, the small ball suspended at the center of the other drum jumps to the rhythm of the drumming. That is, when an object vibrates and produces sound, it causes other nearby objects to vibrate together. ★Scientific Principle: This exhibit demonstrates the principles of sound wave transmission and resonance. By striking one drumhead to cause the other drum to vibrate, participants can intuitively experience the phenomenon where two objects with the same vibration frequency, when one vibrates, the other also vibrates.

  ★Exhibit Content: Sound wave transmission, resonance phenomenon acoustics science popularization mechanical interactive experience ★Interaction: Strike the drumhead, observe the vibration model of the ball on the other drumhead ★Operation: 1. Pick up the drumstick and strike one of the drumheads. 2. Observe the jumping of the small ball suspended at the center of the opposite drum to intuitively experience the resonance phenomenon. 3. Change the striking force multiple times to compare the changes in the vibration amplitude of the ball. ★Exhibit Description: "Resonance Drum" is a vertical floor-standing science popularization exhibit on the theme of acoustic resonance, belonging to the acoustics science popularization exhibition area, and is a recommended exhibit by KexMall. The exhibit uses a white square steel structure frame base, with two yellow drums of identical specifications installed parallel inside the frame, one of which has a lightweight ball suspended on the inside. The lower storage platform of the frame is equipped with drumsticks. The two drums have the same natural vibration frequency. Striking one drumhead generates sound waves that propagate through the air, causing the other drumhead to undergo forced vibration, which drives the ball to jump accordingly, intuitively demonstrating the resonance phenomenon and helping the audience understand sound wave transmission and the conditions for resonance. ★Scientific Principle: 1. A vibrating object that produces sound propagates sound waves through the air. When two objects have the same natural vibration frequency, the sound waves generated by one object's vibration will excite the other object to vibrate synchronously. This phenomenon is called resonance. 2. Striking the drumhead causes the drumhead to vibrate and produce sound waves. The sound waves are transmitted to the other drumhead, causing the drumhead to resonate, which in turn drives the suspended ball to jump. The greater the striking force, the stronger the sound wave energy, and the larger the vibration amplitude of the ball.
