An acoustic model of the Tapped Horn loudspeaker

摘要

A lumped-parameter model of the Tapped Horn loudspeaker - a design where the loudspeaker driver radiates into the throat as well as the mouth of the horn simultaneously - is presented. The model enables the estimation of the far-field sound pressure response from the Thiele/Small parameters of the loudspeaker driver and an additional analytic two-port matrix representation of the Tapped Horn. Simulations, performed using the model for subwoofers, are compared to measurements from an actual loudspeaker.
