FKTHYO Wooden Speaker Resonance Physical Acoustics Experimental Equipment Teaching Tuning Fork Kit 256 Hz Tuning Fork with Wooden Resonant

Description

• *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 is chrome-plated; the resonance box is made of pine.The principle of tuning fork vibration is that resonance theory has an inherent oscillation frequency, also called resonance frequency.
• *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 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 is coated with a non-acid anti-rust oil. After the tuning fork is used, it should be cleaned with a soft cloth and thoroughly coated with anti-rust oil, 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.

Description:
The principle of tuning fork vibration is that resonance theory has an inherent oscillation frequency, also called resonance frequency.
When the object is placed in its natural frequency, that is, the resonant frequency environment, it will react to the frequency, and even Vibrate at the same frequency

Performance and specifications:

Composition:
tuning fork*1
resonance box*1
tuning fork mallet*1

Material: The tuning fork is made of high-quality 45# round steel silver, and the is chrome-plated; the resonance box is pine.

Dimensions: the total length of the tuning fork is about 200mm/7.87 in; the thickness of the fork is 5.58.5mm/0.21*0.33 in; the resonance box is 300*90*53mm/11.81*3.54*2.08 in; the length of the tuning fork hammer is about 190mm/7.48 in

Weight: The net weight of a set is about 310g

When used, the fork handle is clamped, and a soft rubber or other flexible soft object is used to strike, so that 256 Hz sound waves can occur. Be careful not to use hard objects or hard rubber cymbals and knock at the table, as the sound waves emitted in these cases may contain a large number of secondary waves.

Precautions:
After the tuning fork is used, it should be cleaned with a soft cloth and thoroughly coated with anti-rust oil, stored in a dry place to prevent rust.
