Abstract :
The electrical and physical parameters which are of interest in loudspeaker design are discussed. The analysis of loudspeaker action on the basis of its analogy to a vibrating rigid disk is presented. The limitations of such an analysis are indicated. Electromechanical analogies are used to formulate an equivalent electro-mechanical circuit from which loudspeaker performance factors can be derived. Design criteria for commercial and "hi-fi" units are developed. Means of improving loudspeaker performance, particularly at low audio frequencies, are discussed.
