AB  - Acoustic responses of an axisymmetric cone-type loudspeaker mounted in an infinite baffle have been analyzed as an electro-mechano-acoustic transducer by applying the Finite Element Method; conical shell elements to the mechanical system and triangular ring elements to the acoustic system. The outer semi-infinite space where sound is emitted from the cone speaker is treated analytically by applying the Green’s function. The mechano-acoustic system of the cone speaker is connected to the electrical system by an electro-mechanical equivalent circuit. The calculated sound pressure responses are compared with measured results, demonstrating that the calculated responses are very good predictors of measured results.
