This can be done in a few ways

A rose vibrator uses electricity to create vibrations. This can be done in a few ways, but the most common way is to have an electric motor that turns on when you turn the switch. The motor is connected to a battery which sends power through a wire that attaches to the motor. When you turn on your g spot stimulation and move it around, the electric current will travel through this wire and cause vibrations in whatever part of your body you are holding or pressing against.
