What are Speakers?

Speakers are devices that make sound. They are made up of different parts that work together to create sound, so we can hear music, voices, and all kinds of other sounds.

Parts of a Speaker

1. Speaker Cone: This is the part of the speaker that moves back and forth to create sound waves.

2. Magnet: The magnet is a part of the speaker that helps the cone move and create sound.

3. Voice Coil: This is another important part of the speaker that helps create sound. It's like the engine of the speaker.

4. Diaphragm: The diaphragm is a thin piece of material that moves when the speaker is playing sound.

How Speakers Work

When the speaker gets an electrical signal from a device, like a phone or a computer, it sends that signal to the voice coil. The voice coil then creates a magnetic field that interacts with the magnet, making the cone move back and forth. This movement creates sound waves that travel through the air and into our ears, so we can hear the sounds that the speaker is making.
