A loudspeaker is an electroacoustic transducer a device which converts an electrical audio signal into a corresponding sound. The most widely used type of speaker in the 2010s is the dynamic speaker, invented in 1925 by Edward W. Kellogg and Chester W. Rice. The dynamic speaker operates on the same basic principle as a dynamic microphone, but in reverse, to produce sound from an electrical signal.
When an alternating current electrical audio signal is applied to its voice coil, a coil of wire is suspended in a circular gap between the poles of a permanent magnet, the coil is forced to move rapidly back and forth due to Faraday’s law of induction, which causes a conically shaped diaphragm attached to the coil to move back and forth, pushing on the air to create sound waves. Besides this most common method, there are several alternative technologies that can be used to convert an electrical signal into sound.
The sound source which is; a sound recording or a microphone, must be amplified or strengthened with an audio power amplifier before the signal is sent to the speaker.
Speakers are typically housed in a speaker enclosure or speaker cabinet which is often a rectangular or square box made of wood or sometimes plastic.
The enclosure’s materials and design play an important role in the quality of the sound. Where high fidelity reproduction of sound is required, multiple loudspeaker transducers are often mounted in the same enclosure, each reproducing a part of the audible frequency range.
In this case the individual speakers are referred to as “drivers” and the entire unit is called a loudspeaker. Drivers made for reproducing high audio frequencies are called tweeters, those for middle frequencies are called mid-range drivers, and those for low frequencies are called woofers. Smaller loudspeakers are found in devices such as radios, televisions, portable audio players, computers, and electronic musical instruments. Larger loudspeaker systems are used for music, sound reinforcement in theatres and concerts, and in public address systems.
At Irukka music mall, Nigeria’s number one sound equipment mall, you get wharfedale professional sound speakers at affordable prices, gotten from the UK where it is originally designed using eco-friendly materials and user friendly mode to gain it attraction amongst class of speaker manufacturers. Wharfedale Pro known for loudspeakers is a subsidiary to International Audio Group.
Wharfedale pro was founded in 1932 by Gilbret Briggs, which became Britain’s leading manufacturers of audiophile equipment, specifically loudspeakers. Innovations introduced by Wharfedale under Briggs included such basics as the two-way loudspeaker and the ceramic magnet. In the 1950s and 1960s, Wharfedale became famous for its technique of eliminating cabinet resonances by using a double cabinet, with the space between the inner and outer shells filled with sand. Purchasers of the loudspeaker systems would receive the appropriate quantity of sand which had been shipped from Wharfedale in England.
