Abstract

An audio reproduction apparatus (3) includes a primary audio amplifier (31) having an output side (310) for outputting audio signals, and a plurality of auxiliary audio amplifiers (32) coupled electrically in series to the primary audio amplifier (31). Each of the auxiliary audio amplifiers (32) has an input side (320) for receiving the audio signals from the primary audio amplifier (31), a signal current generating device (324) coupled electrically across the input side (320) such that the audio signals pass through the signal current generating device (324), a current inducing device (323) disposed adjacent to the signal current generating device (324) for generating induced audio signals when the audio signals pass through the signal current generating device (324), an auxiliary amplifier (322) coupled electrically to the current inducing device (323) for amplifying and outputting the induced audio signals generated thereby, and a loudspeaker (333) coupled electrically to the auxiliary amplifier (322) for reproducing the induced audio signals amplified by the auxiliary amplifier (322). <IMAGE>
