Patent ID: 8103037

Claim:
A system for producing parameters of bass-enhanced loudspeaker enclosure is used to obtain a frequency ratio, a duct length and a cavity volume length through the definition of a low-frequency extended frequency, a mass ratio and a port radius and under fixed mechanical system resonance frequency and a mechanical system mass; the system for producing parameters of bass-enhanced loudspeaker enclosure comprising of: an initial normalized frequency device, which is used to obtain an initial normalized frequency through the low-frequency extended frequency and the mechanical system resonance frequency; an acoustic quality and quantity device, which is used to obtain an acoustic mass through the mass ratio and the mechanical system mass; a duct length device, which is used to obtain the duct length through the acoustic mass and the port radius; a frequency ratio device, which is used to obtain the frequency ratio through the initial normalized frequency and the mass ratio; an acoustic system resonance frequency device, which is used to obtain an acoustic system resonance frequency through the mechanical system resonance frequency and the frequency ratio; and a cavity volume device, which is used to obtain an acoustic compliance through the acoustic system resonance frequency and to obtain the cavity volume through the acoustic compliance.
