## Description

DIY acoustic suspension module, allows a polystyrene ball to be levitated between two ultrasonic emitters, ideal for educational demonstrations and lab experiments. Operates at 12VDC, uses 16mm speakers, generates ultrasound at 40MHz and includes expanded polystyrene for quick testing.
The ultrasound generator module that allows the levitation of ultralight objects using a frequency of 40MHz.
The kit includes a piece of expanded polystyrene that you will use for levitation.
This product does not necessarily have a practical purpose but can be used for educational purposes to demonstrate the idea of using sound waves to manipulate physical objects.
Specifications:
Supply voltage: 12VDC
Suspended object: Ball of expanded polystyrene
Ultrasound diffuser diameter: 16mm
Generated frequency: 40MHz
Use:
A ball will break from the expanded polystyrene. Power the module at 12VDC, turn on the ultrasonic emission and place the ball between the two ultrasonic emitters. The sound wave generated will keep the polystyrene ball in suspension.
