A Hands-on kit that teaches the principles of sound induction/conduction. When students bite on the wooden rod, the frequencies of the attached audio signal, from a radio, is then transmitted from their teeth to their ears. Includes activity material for five students and an instruction manual.

To produce mechanical vibrations when used with a signal generator. The input is fed to a coil, which is mounted within the field of a cylindrical permanent magnet. The unit is mounted on a strong base and is enclosed in a plastic case. The coil and magnet assembly are protected from the entry of foreign particles. A threaded extension of the armature allows attachment of the item to be vibrated, e.g., plates for chladni’s figure experiments. 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. 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. The unit is electrically secured by means of a fuse. Avoid long periods of sustained rapid vibration and keep dry as moisture will damage the mechanism.

Loop piano wire is an accessory for vibration generator. It is used to demonstrate the wave motion, i.e., for demonstrating the relationship between frequency and the number of vibrational nodes.
