This is the same principle that makes your phone

Rose vibrators work by taking advantage of electricity to create vibrations. This is the same principle that makes your phone, computer and other devices work.Electricity is a form of energy that can be used to do a lot of things, including powering up your favorite rose flower toys. The only difference between rose vibrators and other types of vibrators is that it uses electricity instead of batteries or another power source like solar panels or wind turbines.Vibrators are generally powered by batteries or electricity from a wall outlet (although some models can use USB chargers). Rose vibrators require an external power source because they're not waterproof—that means you'll need to plug them into an outlet in order for them to function properly with no risk of water damage!
