Propagation Vibration Experimental Instrument Tuning Fork Set with Wooden Resonance Box and Beater Resonance Tuning Fork Group Sound (256Hz, 320Hz, 384Hz, 512Hz)

* Tuning fork is the basic instrument of acoustics. It demonstrates the occurrence of sound, the interference of sound can measure the speed of sound and verify the conduction of sound waves, and can do various other acoustic experiments. * The tuning fork is forged from high-quality 45# round steel, and the surface is chrome-plated; the resonance box is made of pine. * Insert the tuning fork into the socket of the resonance box, and hit the tuning fork with a rubber hammer or other elastic objects, which can emit sound waves with a frequency of 256, 320, 384, 512 cycles per second. * The tuning fork must be prevented from being dropped and subject to high heat to prevent frequency changes. The excitation fork must be knocked with a soft hammer. After use, the surface is coated with a non-acid anti-rust oil. * The tuning fork and the resonance box should have a reliable connection. Inserting and removing the tuning fork should avoid shaking to prevent the jack from becoming a horn shape and causing looseness, which will affect the experimental effect.
