It is the battery, it's just like a motor example, say you have a red wire a blue wire and a black and green wire you would tie those to the battery inside so it is like a regular brush in side a case. Also, the people who make them put a hole in the battery and the put the wires in it so u should get a a+ on this cause I'm writing about this because my dad works in a toothbrush factory.
There is no radiation in a Sonic toothbrush. An electric motor powered by a rechargeable battery in the base causes the two opposing magnets in the head to vibrate rapidly causing it's " sonic" effect.
If your looking for things that vibrate to use as a dildo try using an electric toothbrush or electric razor. Or if your looking for something that vibrates to rub against your clitoris then try using a mobile phone, wii remote, games console controller, a really loud speaker, washing machine or place your clitoris against a corner of a table and move up and down. Boy it feels good. Good luck & remember, enjoy the pleasure :)
kinetic. Vocal Cords vibrate (kinetic energy) causing vibrations to move through the air (kinetic), which cause the ear drum to vibrate (kinetic), which induces electric impulses in the brain (electric).
an electric motor with an off-balance weight on its shaft.
The electric and magnetic field vibrate perpendicular to the direction in which the light wave propagates (and perpendicular among themselves). Light is thus a transverse wave.
it can be made to vibrate by putting an electric current through it
oral b vitality i love it There's not much evidence that electric toothbrushes are better than manual toothbrushes. But it's very clear that they're not worse. In the case of the ones with timers, their biggest benefit is probably just getting you to brush as long as you should (two or three minutes). There is some evidence that electric toothbrushes that spin in both directions, like some made by Oral-B, are better than manual brushes. My dentist recommended a two-speed electric toothbrush. The faster speed is for your teeth, the slower speed is for your gums. You need to be gentle with your gums.
That is called an electromagnetic wave.
It converts the electric energy into vibrations which are sound energy.
Well, It depends what type of guitar you are talking about. An acoustic guitar's strings vibrate into the body(sound box) of the guitar and the vibrations resonate in there and escape through the hole. An electric guitar however, has it's strings vibrate and magnetic coils pick up the vibrations and convert them into electrical power, through a chord, and into the amplifier. Then Bon Scott yelled "Let there be guitar!..."
The bonded particles are constantly vibrating and as they are given more energy (such as by heating them) they convert that energy into kinetic energy meaning that they vibrate more until they vibrate fast enough to break the forces holding them together.
Sound waves are mechanical waves, NOT electromagnetic waves. Mechanical waves need a substance to pass through, that is, they need some sort of surface to vibrate against to send compression waves through to the surrounding air. Electromagnetic waves however may travel through empty space as they have no need for a surface, instead, they need only electric and magnetic fields that are present in empty space to pass through. (vibrating electric fields will, in turn, vibrate the magnetic field, which will then trigger a nearby electric field to vibrate, which will make another magnetic field to vibrate, and this is how electromagnetic waves may travel through empty space, but mechanical waves may not)
