Computer speakers, or multimedia speakers, are speakers sold for use with computers, although usually capable of other audio uses, e.g. for an MP3 player. Most such have an internal amplifier and consequently require a power source, which may be by a mains power supply often via an AC adapter, batteries, or a USB port. The signal input connector is often a 3.5 mm jack plug (usually color-coded lime green per the PC 99 standard); RCA connectors are sometimes used, and a USB port may supply both signal and power (requiring additional circuitry, and only suitable for use with a computer). Battery-powered wireless Bluetooth speakers require no connections at all.

They are transducers that convert electromagnetic waves into sound waves. It 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 speaker simply amplify the analog electromagnetic waves into sound waves. Since sound waves are produced in analog form, digital speaker must first convert the digital input to an analog signal, then generate the sound waves.

Speakers typically come in pairs, which allows them to produce stereo sound. This means the left and right speaker transmit audio on two completely separate channels. By using two speaker, music sounds much more natural since our ears are used to hearing sounds from the left and right at the same time. Surround systems may include four to seven speaker (plus a subwoofer), which creates an even more realistic experience.
