Our device is capable of generating between 0.1Hz and 100 kHz. Unlike normal sounds, it can generate square as well as sine waves.
Square waves are signals that instantaneously shift between two separate levels. For convenience, it has six levels. A knob located in the upper right corner precisely controls the frequency.
There is also a jack for a 5.5-watt speaker, which is controlled by a dedicated amplitude knob. The entire unit runs on 110 V AC. An included cord allows you to plug the device into a wall outlet.
Provides mechanical oscillations when given input signals from oscillator or AF oscillator.
A specially designed coil system enables the unit to be operated at its maximum rating for a prolonged period without any damage due to overheating.
The frequency response encompasses the whole of the audio spectrum and beyond. Electrical input via a pair of 4mm shielded sockets and oscillating mechanical output is available through a shaft at the top.
A locking arrangement provides safety to the apparatus during storage or transportation by blocking the motion of shaft.
Show transverse and longitudinal waves in an entertaining and age old fashion. Our flat metal "wavy spring" is 75 mm in diameter and 100 mm tall. Extends to nine meters. Use either horizontally on the floor or table and extend by cord from on high.
