Ultrasonic Acoustic Levitation DIY Kit – 40KHz Mini Levitator
Ultrasonic Acoustic Levitation DIY Kit – 40KHz Mini Levitator
Ultrasonic Acoustic Levitation DIY Kit – Watch Objects Float in Mid-Air!
Experience the magic of physics with this Mini Acoustic Levitator DIY Learning Kit by diymore. Powered by ultrasonic standing wave technology, this compact 12V device suspends lightweight objects — like foam balls and tiny particles — completely in mid-air with no strings attached. It's the perfect hands-on project for students, hobbyists, and DIY electronics enthusiasts who want to explore the fascinating world of acoustic physics.
How It Works
The levitator emits ultrasonic waves at 40 KHz using two transducer heads. These waves travel toward each other and overlap, creating a standing wave. At the wave's pressure nodes, lightweight objects (2–3 mm diameter) experience an upward acoustic force that counteracts gravity — achieving stable, contactless suspension in the air.
Key Features
- 🔊 40 KHz Ultrasonic Frequency – Generates a stable standing wave field for consistent levitation
- 🎯 Levitates tiny objects – Foam balls, small particles, and similar lightweight items (2–3 mm diameter)
- ⚡ Low Power Consumption – Runs on DC 12V (0.5–1A); efficient and safe for long sessions
- 🛠️ Two Set Options – Choose the DIY loose-parts kit to build and solder yourself, or the pre-assembled finished unit ready to use out of the box
- 🎓 Educational by Design – Ideal for STEM learning, science fairs, and electronics courses
- 🌡️ Wide Operating Range – Reliable from -25°C to 85°C

Frequently Asked Questions
Q: What kinds of objects can the ultrasonic acoustic levitator suspend?
A: The mini acoustic levitator can suspend very lightweight objects measuring approximately 2–3 mm in diameter. Common examples include small foam balls, tiny particles, and other similarly light and small items. Heavier or larger objects will not levitate effectively due to the acoustic force limitations at this frequency and power level.
Q: Do I need soldering experience to assemble the DIY Kit (Set I)?
A: Basic soldering skills and familiarity with electronic components are recommended for Set I, as you will need to solder components onto the PCB boards. If you prefer a no-assembly option, choose Set II — the fully pre-assembled and tested finished unit that works right out of the box with a 12V DC power supply.
Q: What power supply do I need to run this acoustic levitator?
A: The levitator requires a DC 12V power supply delivering between 0.5A and 1A. A standard DC wall adapter with a DC005 barrel connector is compatible. Note that the power adapter is not included in the kit — please ensure you have a suitable 12V supply before ordering.
Q: Is this acoustic levitation kit safe for children and classroom use?
A: The device operates at 40 KHz, which is above the range of human hearing, so there is no audible noise. The main board may experience slight warmth during operation, which is normal. The kit is generally suitable for supervised educational settings. Adult supervision is recommended during the soldering assembly of Set I. Always follow standard electronics safety practices.
