Abstract

The invention relates to a resonance demonstration instrument and a demonstration method thereof. A sound insulation cylinder is arranged on a pedestal, a sound insulation baffle plate is arranged on the central section of the sound insulation cylinder, and a support shaft is fixedly installed on the central section of the sound insulation baffle plate. A first rotating disc and a second rotating disc are respectively installed on the two ends of the support shaft through a first bearing and a second bearing, and uniformly distributed limiting holes are arranged in the outer side surfaces of the first rotating disc and the second rotating disc. Splined holes corresponding to the limiting holes are arranged in the two end faces of the support shaft, and limiting through nails are arranged in the splined holes and limiting holes. A resonance generator is arranged on the circumference direction of the first rotating disc, and a reception port is arranged in the upper portion of the resonance generator and connected with an amplification port through a reception pipe. A resonance reception device arranged on the circumference direction of the second rotating disc and corresponding to the resonance generator is arranged on the outer side of the amplification port. Resonance phenomenon can be directly demonstrated through the resonance demonstration instrument and the demonstration method thereof, thereby facilitating observation and enhancing understanding of the phenomenon.

Description

technical field [0001] The invention relates to a physical demonstration device, in particular to a resonance demonstration instrument and a demonstration method thereof. Background technique [0002] Resonance is a very high-frequency technical term in physics. It refers to the situation where a physical system vibrates at a specific frequency with a larger amplitude than other frequencies; these specific frequencies are called resonance frequencies. At the resonant frequency, small periodic vibrations can produce large vibrations because of the kinetic energy stored in the system. When the resistance is small, the resonant frequency is approximately equal to the natural or natural frequency of the system, which is the frequency at which it oscillates freely. There are many resonance phenomena in nature, such as: the acoustic resonance of musical instruments, the orbital resonance between the satellites of some Jupiter-like planets in the solar system, the resonance of the...
