speaker

A device that converts analog audio signals into the equivalent air vibrations in order to make audible sound. When CRT monitors were the norm, speakers designed for computers were shielded to avoid magnetic interference with the CRT's magnetic coil.

Getting Smaller All the Time
Starting in the 1990s, vendors began to offer higher-quality computer speakers. Similar to home theater and stereo systems, the systems include a pair of small speakers for the midrange and high (treble) frequencies and a large subwoofer for the low end (bass). The small speakers are placed in a left/right stereo orientation, while the subwoofer can be located anywhere on the floor because bass signals are omnidirectional. See sound card, Bluetooth speaker, parametric speaker and subwoofer.

Speaker

 

the leader of the lower house (or of a unicameral parliament) in the parliaments of some bourgeois countries. The office was first introduced in 1377 in England. It was subsequently adopted by the parliaments of countries belonging to the British Empire, such as Australia, Canada, New Zealand, Ireland, India, Malaysia, Kenya, and Liberia. Although the speaker is officially elected, he is actually appointed by a faction of the majority. The speaker directs discussion in parliament, interprets rules of procedure, and oversees the officials of the house. He is the official representative of the house in dealings with the executive power.
