Loudspeakers are critical to any audio system. From tweeter speakers to woofer speakers, loudspeakers are the components that provide movies, music, and sports with sounds that are often taken for granted.

Microphones convert sound into electrical impulses that can be recorded onto some form of storage media. Once captured and stored, it can be reproduced at a later time or place. Hearing recorded sound requires a playback device, an amplifier, and, most critically, a loudspeaker.

What Is a Loudspeaker?

A loudspeaker is a device that converts electrical signals into sound as the result of an electro-mechanical process.

Speakers typically incorporate the following construction:

A metal frame or basket, within which all the speaker components are placed.

A diaphragm that pushes air out through vibration. The vibration patterns reproduce the desired sound waves received by your ears. The diaphragm is often referred to as the cone. Although a vibrating cone is commonly used, there are some variations, which are discussed below.

An outer ring of rubber, foam, or other compatible material, referred to as a surround. Not be confused with surround sound or surround speakers, the surround holds the diaphragm in place while providing enough flexibility to vibrate. Additional support is provided by another structure, referred to as a spider. The spider makes sure that the vibrating speaker diaphragm and surround do not touch the outer metal frame.

A voice coil wrapped around an electromagnet is placed at the back of the diaphragm. The magnet or voice coil assembly provides the power to make the diaphragm vibrate according to the received electrical impulse patterns.

Cone speakers also have a little bulge that covers the area where the voice coil is attached to the diaphragm. This is referred to as the dust cap.
