[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
portable stereo music listening apparatus in which a listener in a walk can listen to music or the
like of HiFi stereo reproduction or other sounds with both ears.
[0002]
2. Description of the Related Art A conventionally known stereophonic sound reproducing
apparatus is a so-called stationary stereo apparatus, which is used by being fixed at a
predetermined place in a room.
[0003]
In addition, although a portable stereo sound reproducing apparatus has recently been
developed, this portable stereo apparatus has the same basic structure as a conventional
stationary stereo apparatus, and has the point that a battery can be used only as a power supply.
It only differs.
[0004]
This is that when listening to stereo music and the like conventionally, it is possible to reproduce
high-performance stereo sound more effectively if the loudspeakers are made larger and a
plurality of speakers are separated by a predetermined distance or more. It is nothing else
because it was based on common sense.

On the other hand, so-called pocket-sized radio or cassette tape recorders are also being
developed, but they are not for use as stereo sound reproduction devices but as general
monaural sound reproduction devices because they have limitations on the dimensions of the
speakers and the installation positions of the speakers. It is designed.
Thus, these pocket-sized radio or tape cassette recorders have a single speaker, and the
earphones used as auxiliaries have been one-ear type.
