AB  - The acoustical characteristics of an axisymmetric horn loudspeaker with an elastic diaphragm are calculated by applying the finite element method to both the elastic disphragm and the acoustic cavity of a horn mounted in a rigid infinite baffle. The acoustic reaidation into the semi-infimite space is treated analytically in terms of the velocity potential that is given as the integral of the product of particle velocity and Green's function. Vibrational behavior of the diaphragm, driving-point impedance, sound-pressure distribution inside the horn, and near-field and far-field acoustic radiation are presented for discussion. The experimental validity of the calculated characteristics is confirmed for the horn loudspeaker in far-field sound-pressure response.
