[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an
audio output device for outputting music and the like stored in a storage medium formed of a
memory card.
[0002]
2. Description of the Related Art An audio apparatus (corresponding to an audio output
apparatus) for reproducing music information stored in a storage medium is required to be
compact so that music can be heard at a desired place.
[0003]
For this reason, audio devices have come to use a mini disk as a storage medium, and a
speakerless system that listens to music stored on a mini disk by earphones or headphones.
[0004]
This structure has the advantage of having a smaller body due to the lack of speakers, but the
pleasure of listening to music through the speakers is lost.
[0005]
Therefore, when an external output terminal is provided on the main unit and you want to listen
to music with a speaker, separately connect the speaker device to the external output terminal

via a cable, and output the music with the speaker device in monaural or stereo The thing is
done.
[0006]
[Problems to be solved by the invention] However, when listening to music in monaural, when
listening to music in stereo, it is necessary to connect the main unit and the speaker device with a
cable, so the work until listening to music is troublesome It is.
[0007]
For this reason, for example, listening to music outdoors is likely to be troublesome.
Moreover, even when listening to music in monaural, it is necessary to prepare three persons, a
main body, a speaker device and a cable.
[0008]
Therefore, it is conceivable to attach a speaker device in advance to the main body of the minidisc type audio device.
[0009]
However, since the mini-disc type requires a mechanical structure such as a part for containing
the mini-disc and a mechanism for rotating the mini-disc, when combined with the speaker
device, the external device becomes considerably large and the compactness of the audio device
itself is lost. It will be broken.
[0010]
For this reason, the feature of being able to easily carry and listen to music anywhere is lost.
Especially when two speaker devices are attached, the convenience is totally lost.

[0011]
Therefore, it is an object of the present invention to use a memory card characterized in that
reproduction can be performed without the need for a rotation mechanism such as a mini disk,
eliminating the need for cable connection work, and further reducing the compactness of the
device. It is an object of the present invention to provide an audio output device that allows a
user to easily listen to music from a speaker in monaural or stereo.
[0012]
SUMMARY OF THE INVENTION In order to achieve the above object, the audio output apparatus
according to the first aspect of the present invention has a stationary speaker, a slot into which a
memory card can be inserted, and music information read from the memory card into an audio
signal. A first speaker body configured by incorporating player means to be changed and output
from the speakers, and a second speaker body configured from stationary speakers, and the first
speaker body and the second speaker body include: A monaural mode in which audio is
transmitted from the first speaker body to the second speaker body by a communication device
connected by wireless communication, and the first speaker body outputs audio only from the
first speaker body by turning on and off the communication device; It is possible to switch to a
stereo mode in which sound is output from both of the first speaker body and the second speaker
body.
[0013]
That is, the memory card has a considerably smaller external shape than the mini disk, and does
not require a rotation mechanism such as the mini disk, and is characterized in that music
information can be output.
[0014]
Therefore, even when the slot of the memory card and the player means are incorporated into
the stationary speaker, the first speaker body is suppressed to the outer shape substantially
equivalent to the stationary speaker, and the compactness is maintained as it is.
[0015]
Moreover, when listening to music in monaural, it is easy to listen to music from the speakers by
taking advantage of this compactness and carrying only the first speaker body to a desired
location.

When listening to music in stereo, place the second speaker body adjacent to the first speaker
body, turn on wireless communication, transmit audio information from the first speaker body to
the second speaker body, and use both speaker bodies. By outputting audio from, you can easily
listen to music in stereo without the need for cumbersome cable work.
