Abstract
A method for generating a prediction curve for acoustic load of a loudspeaker, the loudspeaker including a horn and a diaphragm, one end of the horn is defined as a throat, and the outside of the other end of the horn is free space, wherein a sound wave from the diaphragm passes through the throat and gradually diffuses to the free space outside the other end of the horn, includes defining a cross section or a surface, where the cross section is a cross section of the throat, and the surface is a surface of the diaphragm; integrating a sound pressure value of the cross section or the surface to obtain an effective sound pressure, or integrating acoustic energy of the cross section or the surface to obtain a radiated sound power; and generating the prediction curve according to the effective sound pressure or the radiated sound power, where the prediction curve is an acoustic impedance curve or an acoustic power curve.
