AB  - Acoustical characteristics of an axisymmetric horn loudspeaker with an elastic diaphragm are calculated by applying the Finite Element method to both the elastic diaphragm and the acoustic cavity of a horn mounted in a rigid infinite baffle. Acoustic radiation into the semi-infinite 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, nearfield and fourfold acoustic radiation are presented for discussion. Experimental validity of the calculated characteristics is confirmed for the horn loudspeaker in fourfold sound pressure responses.
