What is a Subwoofer?

A subwoofer is a speaker. It is designed to play low-pitched sounds. These are also known as bass. It covers the lowest range of frequencies. These are from about 20 to 200 hertz.


Parts of a Subwoofer

A subwoofer has several key parts. They all work together to produce sound. Here is a list of these parts:

  • Cone: Moves back and forth to push air.
  • Suspension: Helps the cone move smoothly.
  • Coil: Turns electric signals into movement.
  • Magnet: Works with the coil to move the cone.
  • Enclosure: A box that holds everything.

How Does a Subwoofer Produce Sound?

Let’s break down the steps:

  1. Electric signals come from your sound system.
  2. These signals go to the subwoofer’s coil.
  3. The coil creates a magnetic field.
  4. This field pushes against the subwoofer’s magnet.
  5. The cone moves because of this push and pull.
  6. As the cone moves, it pushes air.
  7. This moving air is what we hear as sound.
