Designing, Building, and Testing Your Own Speaker System with Projects by David B.Weems (McGraw-Hill/TAB Electronics, ISBN 0-07-069429-X) Loudspeakers, Dynamic, Magnetic Structures and Impedance EIA RS-299-A standard
The electroacoustic mechanism most widely used in speakers to convert the electric current to sound waves is the dynamic or electrodynamic driver, invented in 1925 by Edward W. Kellogg and Chester W. Rice, which creates sound with a coil of wire called a voice coil suspended between the poles of a magnet.
Dave Wilson of Wilson audio, used JansZen tweeters in his famous, WAMM, Wilson Audio Modulator Monitor. That speaker sold for $220,000 a pair when it was discontinued. The developers of the Tri-Ergon sound-on-film sound film system had developed a primitive design of electrostatic loudspeaker as early as 1919.
A loudspeaker (commonly referred to as a speaker or, more fully, a speaker system) is a combination of one or more speaker drivers, an enclosure, and electrical connections (possibly including a crossover network). The speaker driver is an electroacoustic transducer [1]: 597 that converts an electrical audio signal into a corresponding sound. [2]
Speaker wire is a passive electrical component described by its electrical impedance, Z.The impedance can be broken up into three properties which determine its performance: the real part of the impedance, or the resistance, and the imaginary component of the impedance: capacitance or inductance.
reducing the resonances occurring between electromagnetic excitations and structural modes; Electromagnetic noise and vibration mitigation techniques in electrical machines include: choosing the right slot/pole combination and winding design; avoiding resonances match between stator and electromagnetic excitations; skewing the stator or the rotor
