[Detailed description of the invention] The present invention is a stereo playback device KIINL,

111. The external speakers 11L-bh and others Nora # 1 are reproduced. Next, when Jack Ladder
$ 1iK Outer Speaker 4Rf is connected. ? The interlock switch 12 company and its common
Kamiko IR & and the switch Ladder 12a are interlocked and interlocked with this. 611 beast is
applied. However, first, the external skier 4L continues to be dead-no, the tC built-in speaker 2
and the external speaker 4R respectively reproduce L channel and R channel reproduction
signals, and perform stereo reproduction. Further, the built-in speaker idleness is disconnected in
conjunction with the end of the self-external speaker 4Lt's terminal 5LKII.
The L channel and l channel 0 he **** are respectively reproduced from the speaker 4 L @ 41
from the outside speaker 0 L m ? 0 outside, and it becomes stereo re-gold. In addition, in the
above-described 111 m @ 1 l, the reproduction signal is supplied to the output amplifier 111 at
the time of regenerative reproduction, and the output signal is increased to one. When
configured with BIl output amplification, there is no waste that consumes unnecessary power.
When used in a battery-powered stereo playback device, it is effective 11% O for 1111. The same
effect can be obtained even if it is used in a multi-channel stereo reproduction apparatus with
only one reproduction system 040. As described above, according to the present invention, it is
possible to remarkably improve the reproduction operation from selfishness by automatically
switching between no-noll reproduction and stereo reproduction in conjunction with close
reading of a speaker [i good When one speaker is a built-in speaker ?1 overrun # i ? O Prebuilt speaker monaural ? ? ? ?? ?? ?? ?? ?? # ?? ?? ? ? i i ?? ?? ?? ?

consideration of the picture, and to obtain an effect. Brief description of aSm #! 111 Fi present
