Speakers are one of the most common output devices used with computer systems. Some speakers are designed to work
specifically with computers, while others can be hooked up to any type
of sound system. Regardless of their design, the purpose of speakers is
to produce audio output that can be heard by the listener.
Speakers are transducers that convert electromagnetic waves into sound waves. The speakers receive audio input from a device such as a computer or an audio receiver. This input may be either in analog or digital form. Analog speakers simply amplify the analog electromagnetic waves
into sound waves. Since sound waves are produced in analog form,
digital speakers must first convert the digital input to an analog
signal, then generate the sound waves.
The sound produced by speakers is defined by frequency and amplitude.
The frequency determines how high or low the pitch of the sound is. For
example, a soprano singer's voice produces high frequency sound waves,
while a bass guitar or kick drum generates sounds in the low frequency
range. A speaker system's ability to accurately reproduce sound
frequencies is a good indicator of how clear the audio will be. Many
speakers include multiple speaker cones for different frequency ranges,
which helps produce more accurate sounds for each range. Two-way
speakers typically have a tweeter and a mid-range speaker, while
three-way speakers have a tweeter, mid-range speaker, and subwoofer.
