Speakers can be ugly boxes that destroy the aesthetics of the room.
So in order to convert them into a more attractive feature, an inventor in California is filing a patent to make speakers by decorating containers (such as vases or spheres.
First of all, the container is filled with magnetic liquid-an oil containing nanoparticles --
Size of magnetic metal particles.
Then, a large bar magnet is hung in the middle of the fluid, and a coil is wound around the outside of the container.
When the music signal from the amplifier is fed through the coil, it creates a pulsating magnetic field in the iron magnet that interacts with the static magnetic field around the rod magnet.
The magnet vibrates, causing the iron fluid to vibrate, and vibrates with the wall of the container.
As a result, the ornament made a sound in the room.
If the speaker is made of a transparent container and the LEDs are also placed in the fluid, the device will emit a glow that beats with the music.
This is what the DJ ordered.

Intel has come up with a new idea for saving battery power on laptops and phones.
If the computer is idle for a few minutes, a small part of the screen remains active-just like a window.
Therefore, the device can still display incoming messages or websites with much less power consumed at the same time.
Intel's screen has two backlights, one to illuminate the entire display area and the other to illuminate one area --
A tenth of the overall screen size.
When the owner is working hard and using several programs at the same time, the main backlight is turned on so that the entire screen can be used.
However, when only one program runs for a few minutes, such as email or music playback, the light is turned off, the small corner backlight is turned on, and the running program is displayed in the corner window. The mini-
The screen can still display a text message, adjust the title, or flash the news, but only one-
A tenth of the entire screen.
When the owner wants to start using more programs, the screen light switches back to full-
Size display mode. Read the power-

Long flights can prove that the air-conditioning system seems to spread nasty bugs and chemicals in the air around.
But it is not easy to remove the nasal excrement in these air, because the air filter will be blocked soon and needs to be replaced, while UV (
Can kill bugs.
No toxic chemicals will be destroyed.
Now, a team at the University of Florida Research Foundation in the United States has developed an electric shock system that can destroy anything nasty in the air, including anthrax.
Put a bunch of capacitors in one of the air
Pipes for air conditioning systems.
Each capacitor is made of a pair of aluminum sheets coated with several nanometers of insulating alumina.
The capacitor is separated by 100 microns.
When the rough alumina surface passes through a narrow gap between the plates, any particles are temporarily captured in the air.
Applying the voltage to a tightly spaced plate creates a high charge on the insulating surface.
This destroys any creature trapped on the surface and breaks down the compound.
The residue can be removed intermittently by simply heating the plate.
The inventor has tested the system in air containing hard Airto-
Destroy the spores of black fungus.
They claim that electric shocks have proved to be twice as deadly as strong UV rays.
