What's inside a toothbrush?

I used a toothbrush from the brand 'Braun', to find out how the toothbrush looks on the inside. I've cut the outer case on it's lenght.

The inside consist of different parts, assembled in such way that you can remove them out of the outer case in one part. Here's a picture of the inside in one part.

The inside parts: 

When you recharge your toothbrush, the coil supplies electric flux. The electric flux recharges the battery in the toothbrush.

When you turn on the electric toothbrush, the electric flux flows from the battery to the motor, which converts electric energy into mechanical movement. The operation of the toothbrush is explained later on, in this blog.
