HCNT levitation speaker Portable Audio player
Levitation is the process by which an object is suspended by a physical force against gravity, in a stable position without solid physical contact. A number of different techniques have been developed to levitate matter, including the aerodynamic, magnetic, acoustic, electromagnetic, electrostatic, gas film, and optical levitation methods.
This is a levitation Bluetooth speaker. AS you can see, the UFO shape Bluetooth speaker can floating on the trumpet-shaped table lamp.









We applied the first patent in 16 March 2006 for bottom levitation system. Now, it is already patented in China and USA.

For levitation on Earth, first, a force is required directed vertically upwards and equal to the gravitational force, second, for any small displacement of the levitating object, a returning force should appear to stabilize it. The stable levitation can be naturally achieved by, for example, magnetic or aerodynamic forces.
Although any electromagnetic force could be used to counteract gravity, magnetic levitation is the most common. Diamagnetic materials are commonly used for demonstration purposes. In this case the returning force appears from the interaction with the screening currents. For example, a superconducting sample, which can be considered either as a perfect diamagnet or an ideally hard superconductor, easily levitates in an ambient external magnetic field. In very strong magnetic field, by means of diamagnetic levitation even small live animals have been levitated.
Levitation Bluetooth speaker, thanks for HCNT patented of bottom magnetic levitation device:
This is a system device. The system effect the magnet to float and turn in the air.There is only one center point can float the magnet. We make the base to hide the system device. The electrical maglev device can suspend 0-150g, 0-250g, 0-350g, 0-500g, 0-1000g, 0-2000g objects.
