Portable computer speakers are designed to provide sound while outdoors or during transport. They come in compact, lightweight cases and are usually sold in sets. They are mainly used for desktop PCs and laptops, but they are also compatible with other electronic audio devices such as CD and mp3 players. They may be powered by batteries, AC power, or both. They have a power output of up to 10 watts and a frequency response of up to 70 Hz.
Standard portable computer speakers are traditional in style and design. They usually have a 20- to 70Hz frequency response. They usually have built-in bass sound for excellent bass reproduction. They are commonly available in black, white, and gray.
Novelty portable computer speakers have creative designs such as cartoon characters and scientific models. They usually have self-powered in-line amplifiers.
