Tuning Fork Set with Wooden Resonance Box and Beater Resonance Tuning Fork Group Sound Propagation Vibration Experimental Instrument

Composition: tuning fork*4 (256Hz, 320Hz, 384Hz, 512Hz)resonance box*1tuning fork mallet*1Material: The tuning fork is made of high-quality 45# carbon steel with chrome-plated surface; the resonance box is made of pine.Dimensions: The total length of the tuning fork is 197mm/7.75 in, 183mm/7.2 in, 170mm/6.69 in, 157mm/6.18 in; the thickness of the fork is 6×8mm/0.23*0.31 in; the resonance box is 300*93*53mm/11.81*3.66 *2.08 in; the length of the tuning fork hammer is about 183mm/7.2 in;Weight: a set of net weight is about 680gPrecautions:Be careful not to knock with hard objects or the side of the table, because in this case, a large number of sub-waves may be emitted. After the tuning fork is used, it should be wiped clean with a soft cloth, coated with anti-rust oil, and stored in a dry place to prevent rust.

• * 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.
• * 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.
