High fidelity sound spectrum restoring method for compartment of automobile, involves distributing power of signal on combination of loudspeakers, where loudspeakers are arranged for presenting impedance for which signal is dimensioned

摘要

The method involves distributing the power of a sound signal on the combination of impedance loudspeakers (131, 134-136), in a frequency field and/or a spatial field. The loudspeakers are arranged for presenting the impedance for which the sound signal is dimensioned. The combination of the impedance loudspeakers is realized by cabling two pairs of loudspeakers in parallel. The combination of the impedance loudspeakers is supplied by a left-rear outlet (130) of an amplifying stage (100). An independent claim is also included for an acoustic system comprising an impedance loudspeaker.
