Definition: A device that vibrates or causes vibration.

Alright class, settle down, let’s take a look! You’ve come across a word today, “vibrators,” and you want to know what it means. The dictionary gives us a good start – "a device that vibrates or causes vibration.” Let's break that down, nice and slow. "Vibrate" means to shake back and forth, like when you hold your hand out the window on a windy day! Or maybe think about a hummingbird’s wings - they buzz and vibrate really fast. A “vibrator” is something designed to do that shaking – it makes things move with little, quick movements. It's often used in machines or tools, like a small motor that makes a fan spin, or even a tiny speaker that creates sound. Now, I understand you might be thinking about other uses of the word – and yes, there are devices made for personal use that do vibrate. But it’s important to remember the core meaning: it's all about movement, back and forth, creating a shaking action. Does that make sense? Do you have any questions about how vibrations work or what things vibrate in our world around us?
