Abstract:
1. An apparatus for sound using multiple amplifiers, comprising: a sound source generating unit for generating an electric signal from a sound source; N amplifiers which are connected with the sound source generating unit, wherein N is an integer equal to or larger than 2, an output part of the sound source generating unit being connected with an input part of one amplifier selected from the N amplifiers, the N amplifiers being connected in series so that the output part of each amplifier is connected with the input part of another amplifier; and 2N speakers which are respectively connected with left and right output parts of each of the N amplifiers, wherein there is formed a multiple stereo imaging including a first stereo imaging generated by two speakers which are respectively connected with the left and right output parts of one amplifier selected from the N amplifiers; a first mono imaging generated by N speakers which are connected with the left output parts of each of the N amplifiers; a second mono imaging which are connected with the right output parts of each of the N amplifiers; and a second stereo imaging generated by the first mono imaging and the second mono imaging.
