Wave Driver

Product Code: WA-9855


This newly redesigned Wave Driver offers improvements in driving force and amplitude as well as a built-in string guide so tiny parts don’t get lost. It is ideal for vibrating waves in a string, driving Chladni plates to show the vibration modes, or to demonstrate resonance vibrations.

Use a function generator (sold separately) to power this Wave Driver.


  • New improved design
  • Greater amplitude
  • Stronger magnet for stronger force
  • Sturdy construction

Built-in Features

  • 0.5-inch (1.3 cm) rod clamp
  • String slot in driver post
  • Hole through driver post for tying string
  • Fuse protection
  • Shielded banana jacks
  • Rubber base


  • Standing waves in a string
  • Chladni plate resonance modes
  • Demonstration of resonance using vibrating metal strips
  • Demonstration of standing longitudinal waves in a spring

How It Works

A coil inside a cylindrical magnet is driven by a sinusoidal signal which comes from the external function generator that is connected to the Wave Driver’s banana jacks. The coil is attached to a diaphragm that the actuator rod is connected to.
