invention can be arbitrarily modified within the scope of the technical idea. [1] Configuration of
First Embodiment [1.1] Configuration of First Embodiment Next, a schematic configuration of the
sound reproduction output device 10 will be described with reference to FIG. First, an operation
unit 16 performs various operations such as reproduction, stop, fast forward, and the like of the
MD by the user. The operation unit 16 outputs a signal corresponding to the user's operation and
supplies the signal to the control unit 19. The control unit 19 performs control corresponding to
the operation signal from the operation unit 16 on each part of the apparatus. Reference numeral
18 denotes a display unit provided with a liquid crystal screen. The display unit 18 displays the
contents of various operations performed by the operation unit 16 and the contents of setting
contents set by the operation unit 16.
The MD reproduction unit 11 reads out and reproduces stereo audio signals of two channels
from a mini disc (MD) set in the sound reproduction output device 10. When the reproduction of
the MD set in the sound reproduction output device 10 is completed, the MD reproduction unit
11 outputs a reproduction end signal indicating that the reproduction is ended, and supplies the
reproduction end signal to the control unit 19. In the present embodiment, the MD is used as the
recording medium, but the recording medium is not limited to this. For example, a compact disc
(CD), an optical disc, a magneto-optical disc, a cassette tape or the like may be used as a
recording medium. The output setting condition memory 17 is a memory for storing operation
conditions, and stores information according to the operation of the operation unit 16. Here, FIG.
2 is a conceptual view showing stored contents of the output setting condition memory 17. As
shown in FIG. In FIG. 2, the reproduction side information area 171 stores information indicating
whether the sound reproduction output apparatus 10 is used as a reproduction machine or an
external speaker of another sound reproduction output apparatus. In the present embodiment,
two sound reproduction output devices 10 can be connected and linked together, and when two
units are connected, one becomes the reproduction side and the other functions as an external
speaker on the reproduction side. It is supposed to be. A channel type area 172 shown in FIG. 2
stores information for specifying a channel to be reproduced by one's own device and a channel
to be reproduced by another device when two sound reproduction output devices are connected.
Ru. In the illustrated state, the L channel is set to the own apparatus and the R channel is set to
the other apparatus. In the delay time area 173, delay time information for delaying the
reproduction timing in the other device is stored when two sound reproduction output devices
are connected. Reference numeral 15 denotes a terminal into which a headphone plug is
inserted. An output / input terminal 14 is a terminal into which a plug of an output / input cord
for connecting two sound reproducing output devices is inserted. When the plug of the code for
output / input is inserted into the terminal 14, the channel control unit 12 reproduces stereo
sound of two channels reproduced by the MD reproduction unit 11 according to the setting
contents of the output setting condition memory 17. It switches the output destination of the
signal or controls the output destination of the acoustic signal input from the terminal 14.

However, when the plug of the headphone is inserted into the terminal 15, the channel control
unit 12 sets the stereo audio signal of two channels reproduced by the MD reproduction unit 11
regardless of the setting contents of the output setting condition memory 17. Output to terminal
15.
Further, when plugs are inserted into both the terminal 14 and the terminal 15, the channel
control unit 12 gives priority to the terminal 15, and the stereo audio signal of two channels
reproduced by the MD reproducing unit 11. Is output to the terminal 15. Furthermore, when no
plug is inserted into either of the terminal 14 and the terminal 15, the channel control unit 12
reproduces the two channels reproduced by the MD reproduction unit 11 regardless of the
setting contents of the output setting condition memory 17. The stereo sound signal is converted
to a monaural sound signal and output to the built-in speaker 13. That is, when the plug of the
headphone is inserted into the terminal 15, the music can be listened by the headphone, and
when the plug is not inserted into the terminal 14 and the terminal 15, the music can be listened
from the built-in speaker 13. Can. When the control unit 19 receives the reproduction end signal
from the MD reproduction unit 11, the control unit 19 outputs the reproduction end signal to the
terminal 14. Here, the correspondence between the setting contents of the output setting
condition memory 17 and the control in the channel control unit 12 will be described. The
channel control unit 12 performs the following processing on condition that the plug of the
output / input cord is inserted into the terminal 14. First, when the setting content in the
reproduction side information area 171 is ON , the channel control unit 12 outputs a channel
signal according to the setting content in the channel type area 172 to the built-in speaker and
the terminal 14 respectively. . In the case of the setting example shown in FIG. 2, the L channel
acoustic signal is output to the speaker 13, and the R channel acoustic signal is output to the
terminal 14. On the other hand, when the setting content in the reproduction side information
area 171 is OFF , the channel control unit 12 outputs the acoustic signal input from the
terminal 14 to the built-in speaker 13. [1.2] Operation of the First Embodiment First, an
operation example when the sound reproduction output device 10 and the sound reproduction
output device 20 having the same configuration as the sound reproduction output device 10 are
connected as shown in FIG. Will be explained. In the illustrated state, the sound reproduction
output device 10 in which the reproduction side information area 171 is set to "ON" is the side
that reproduces the MD, and the sound reproduction output in which the reproduction side
information area 171 is set to "OFF" The device 20 functions as an external speaker of the sound
reproduction output device 10. The channel control unit 12 of the sound reproduction output
apparatus 10 processes the stereo sound signal reproduced by the MD reproduction unit 11 as
follows according to the setting conditions shown in FIG.
The channel control unit 12 of the sound reproduction output device 10 outputs the sound signal
for L channel to the built-in speaker 13 of the sound reproduction output device 10 and the
09-05-2019

sound signal for R channel via the terminal 14 of the sound reproduction output device 10
Output to the sound reproduction output device 20. Next, the channel control unit 12 of the
sound reproduction output device 20 outputs the sound signal for the R channel input from the
terminal 14 to the built-in speaker 13 of the sound reproduction output device 20. Thereby, the
sound corresponding to the sound signal for the L channel is output from the built-in speaker 13
of the sound reproduction output device 10, and the sound from the built-in speaker 13 of the
sound reproduction output device 20 corresponds to the sound signal for R channel. Sound is
output. [1.2.1] Separate Reproduction Processing Operation Next, referring to FIG. 4, it functions
as a speaker of the sound reproduction output device 10, which is a device that reproduces an
audio signal, and a sound reproduction output device 10. An operation example of the sound
reproduction output device 20 will be described. First, the channel control unit 12 of the sound
reproduction output device 10 determines whether the plug of the output / input cord is inserted
into the terminal 14 (step S1). When it is determined in step S 1 that the plug of the output /
input cord is inserted (step S 1; YES), the channel control unit 12 of the sound reproduction
output device 10 outputs the output setting condition memory The setting contents are extracted
from 17 (step S2). Here, in this operation example, it is assumed that the setting content shown
in FIG. 3 is registered in advance in the output setting condition memory 17. Next, the MD
reproduction unit 11 of the sound reproduction output apparatus 10 reads and reproduces
stereo audio signals of two channels from the MD set in the sound reproduction output
apparatus 10 (step S3). The channel control unit 12 outputs the acoustic signal for the R channel
to the acoustic reproduction output device 20 via the terminal 14 of the acoustic reproduction
output device 10 according to the setting contents (step S 4). When the audio signal is input from
the terminal 14, the channel control unit 12 of the audio reproduction output device 20 extracts
the setting content from the output setting condition memory 17 (step S5). Then, after
recognizing that the reproduction side information area 171 of the extracted setting content is
OFF , the channel control unit 12 reproduces the sound corresponding to the sound signal
for R channel input from the terminal 14 The signal is output from the built-in speaker 13 of the
output device 20 (step S6).
On the other hand, the channel control unit 12 of the sound reproduction output device 10
outputs the sound corresponding to the sound signal for the L channel from the built-in speaker
13 of the sound reproduction output device 10 according to the setting content (step S7). [1.2.2]
Switching Operation of Reproducing Apparatus Next, with reference to FIG. 5, an operation
example for switching the sound reproducing output apparatus on the side of reproducing the
sound signal in the sound reproducing output system 1 will be described. Do. Here, since the
process from step S11 to step S17 shown in FIG. 5 is the same process as the process from step
S1 to step S7 shown in FIG. 4, detailed description will be omitted. As shown in FIG. 5, in the
processing from step S 11 to step S 17, the channel control unit of each of the sound
reproduction output devices 10 and 20 is a stereo recorded on the MD set in the sound
reproduction output device 10. An acoustic signal is output to each internal speaker according to
09-05-2019

the setting contents. Next, the MD reproducing unit 11 that has detected that the reproduction of
the audio signal recorded in the MD set in the audio reproduction output apparatus 10 is
finished notifies the channel control unit 12 to that effect. The channel control unit 12 switches
the content stored in the reproduction side information area 171 of the output setting condition
memory from "ON" to "OFF" (step S18). Then, the channel control unit 12 of the sound
reproduction output device 10 transmits a reproduction end signal to the sound reproduction
output device 20 (step S19). Here, the reproduction end signal is not limited to being transmitted
when all reproduction of the audio signal recorded in the MD is completed. For example, the
reproduction end signal may be transmitted even when the reproduction of the song set by the
user is completed. The channel control unit 12 of the sound reproduction output apparatus 20
that has received the reproduction end signal extracts the setting content stored in the output
setting condition memory, and the content stored in the reproduction side information area 171
is off. To "ON" (step S20). Next, the MD reproduction unit 11 of the sound reproduction output
apparatus 20 reads and reproduces stereo audio signals of two channels from the MD set in the
sound reproduction output apparatus 20 to start reproduction of the MD (step S21). . The
channel control unit 12 outputs the acoustic signal for the L channel to the acoustic reproduction
output device 20 via the terminal 14 of the acoustic reproduction output device 20 according to
the setting content (step S22).
The channel control unit 12 of the sound reproduction output apparatus 10 recognizes that the
content stored in the reproduction side information area 171 of the setting content is OFF
when the sound signal is input from the terminal 14. The sound corresponding to the L channel
sound signal input from the terminal 14 is output from the built-in speaker 13 of the sound
reproduction output device 10 (step S23). On the other hand, the channel control unit 12 of the
sound reproduction output device 20 outputs the sound corresponding to the sound signal for
the R channel from the built-in speaker 13 of the sound reproduction output device 10 according
to the setting contents (step S24). [1.2.3] Delayed Reproduction Operation Next, referring to FIG.
6, the sound output from the sound reproduction output device 20 is delayed compared to the
sound output from the sound reproduction output device 10 An operation example at the time of
output will be described. First, the channel control unit 12 of the sound reproduction output
device 10 determines whether the plug of the output / input cord is inserted into the terminal 14
(step S31). When it is determined in step S 31 that the plug of the output / input code is inserted
(step S 31; YES), the channel control unit 12 of the sound reproduction output apparatus 10
outputs the output setting condition memory The setting contents are extracted from 17 (step
S32). Here, in this operation example, data corresponding to 3 seconds is registered in advance
in the delay time area 173 of the setting content stored in the output setting condition memory
17. Further, when the data stored in the delay time area 173 of the setting content is other than
0, the channel control unit 12 performs monaural processing from each internal speaker 13
regardless of the data stored in the channel type area 172. The sound corresponding to the
sound signal of is output. Next, the MD reproduction unit 11 of the sound reproduction output
09-05-2019
6
apparatus 10 reads and reproduces stereo sound signals of two channels from the MD set in the
sound reproduction output apparatus 10 (step S33). The channel control unit 12 mixes the twochannel stereo sound signals reproduced by the MD reproduction unit 11 and converts the mixed
signals into a monaural sound signal. Then, based on the extracted setting content, the channel
control unit 12 performs acoustic reproduction of a control signal indicating that the monaural
acoustic signal is delayed by 3 seconds from the acoustic reproduction output device 10 in
addition to the monaural acoustic signal. It outputs to the output device 20 (step S34).
At the same time, the channel control unit 12 causes the built-in speaker 13 to output the sound
corresponding to the monaural sound signal (step S35). On the other hand, the channel control
unit 12 of the sound reproduction output device 20 having received the sound signal from the
sound reproduction output device 10 delays the sound by 3 seconds after the sound output from
the internal speaker 13 of the sound reproduction output device 10. The sound is output from
the internal speaker 13 of the sound reproduction output device 20 (step S36). [2] Configuration
of Second Embodiment [2.1] Configuration of Second Embodiment FIG. 7 shows a schematic
configuration of a sound reproduction output system 2 according to an embodiment of the
present invention. As shown in FIG. 7, the sound reproduction output system 2 is configured of
five sound reproduction output devices 10, 20, 30, 40, 50. The acoustic reproduction output
system 2 is an apparatus for reproducing an acoustic signal. Of 5.1 stereo acoustic signals
reproduced by the acoustic reproduction output apparatus 10, an acoustic signal for the front
center (C) channel is an acoustic reproduction output. The sound signal for the front R (FR)
channel is output from the sound reproduction output device 20, and the sound signal for the
front L (FL) channel is output from the sound reproduction output device 30, and the rear R (RR)
is output. The acoustic signal for the channel is outputted from the acoustic reproduction output
device 40, and the acoustic signal for the rear L (RL) channel is outputted from the acoustic
reproduction output device 50. Here, since the general configuration of the sound reproduction
output devices 10, 20, 30, 40, 50 is configured in the same manner as in the first embodiment,
the detailed description of the same portions will be omitted. The MD reproduction unit 11 reads
out and reproduces a 5.1 channel stereo sound signal from a mini disc (MD) set in the sound
reproduction output device 10. FIG. 8 is a conceptual view showing stored contents of the output
setting condition memory 17. As shown in FIG. In FIG. 8, the reproduction side information area
171 stores information indicating whether the sound reproduction output apparatus 10 is used
as a reproduction machine or an external speaker of another sound reproduction output
apparatus. In the present embodiment, five sound reproduction output devices 10 can be
connected and linked together, and when five units are connected, one becomes a device to be
reproduced and another four are reproduced. It is supposed to function as an external speaker.
The connection number area 174 shown in FIG. 8 stores information specifying the number of
connected sound reproduction output devices.
09-05-2019
7
The connection number area 175 stores information for identifying the sound reproduction
output device. In the present embodiment, since the number of connected units is five, the
connection number area 175 stores any number from 1 to 5 . The channel type area 172
stores information specifying the relationship between the sound reproduction output device and
the reproduction channel. In the illustrated state, the C channel is connected to the own device
having the connection number 1 , the FR channel to another device having the connection
number 2 , and the FL channel is connected to the other device having the connection
number 3 . The RR channel is set to another device having the number 4 , and the RL
channel is set to another device having the connection number 5 . The delay time area 173 is
configured to store delay time information for sequentially delaying the reproduction timing in
another device when five sound reproduction output devices are connected. When the plug of
the output / input code is inserted into the terminal 14, the channel control unit 12 is
reproduced by the MD reproduction unit 11 according to the setting contents of the output
setting condition memory 17. The output destination of the stereo audio signal of one channel is
switched, or the output destination of the audio signal input from the terminal 14 is controlled.
Here, when the plug of the headphone is inserted into the terminal 15, the channel when the
plug is inserted into neither the terminal 14 nor the terminal 15 when the plug is inserted into
both the terminal 14 and the terminal 15 The processing function of the control unit 12 is the
same as that of the first embodiment. [2.2] Operation of Second Embodiment Next, with reference
to FIG. 9, an operation example in the case where five sound reproduction output devices are
connected will be described. Here, in the sound reproduction output system 1 according to the
first embodiment, two sound reproduction output devices are connected to each other and each
sound reproduction output device reproduces two channels of sound signals reproduced by one
sound reproduction output device. In the sound reproduction output system 2 according to the
second embodiment, five sound reproduction output devices are connected to each other, and
5.1 channel sound signals reproduced by one sound reproduction output device are output. They
differ in that they are outputted from each sound reproduction output device. First, the channel
control unit 12 of the sound reproduction output device 10 determines whether the plug of the
output / input cord is inserted into the terminal 14 (step S 41). If it is determined in step S41
that the plug of the output / input cord is inserted (step S41; YES), the channel control unit 12 of
the sound reproduction output device 10 is set from the output setting condition memory 17 The
contents are extracted (step S42).
Here, in this operation example, it is assumed that the setting content shown in FIG. 8 is
registered in advance in the output setting condition memory 17 of the sound reproduction
output device 10. Next, the MD reproduction unit 11 of the sound reproduction output device 10
reads out and reproduces a 5.1 channel stereo sound signal from the MD set in the sound
reproduction output device 10 (step S43). The channel control unit 12 of the sound reproduction
output device 10 outputs sound signal information for another channel from which the sound
signal for C channel is removed according to the setting contents to the sound reproduction
09-05-2019
8
output device 20 through the terminal 14. (Step S44). Here, the channel control unit 12 converts
the acoustic signal for the other channel from which the acoustic signal for the C channel is
removed, into the data format shown in FIG. 10, and outputs it as acoustic signal information.
The sound signal information shown in FIG. 10 is made of sound signal information data
including data identification 91 and data content 92. The data identification 91 stores the
number stored in the connection number area 175 of the output setting condition memory 17.
Also, in the data content 92, an acoustic signal for a channel stored in the channel type area 172
of the output setting condition memory 17 is stored. For example, in the sound signal
information data 93 shown in FIG. 10, the data identification 91 is "2", and the data content 92 is
"sound signal for FR channel". Therefore, the sound signal information data 93 is to output the
sound signal for the FR channel from the sound reproduction output device whose connection
number 175 is "2". The sound reproduction output device 20 having received the sound signal
information output from the sound reproduction output device 10 through the terminal 14 of the
sound reproduction output device 20 has a channel number control unit 12 of the output setting
condition memory 17 connected number area 175 The sound signal data of which the data
identification 91 is "2" is separated and extracted from the sound signal information on the basis
of the numbers stored in. Then, the channel control unit 12 extracts the acoustic signal stored in
the data content 92 of the extracted acoustic signal information data as an acoustic signal to be
output. The channel control unit 12 outputs acoustic signal information including acoustic signal
information data other than the extracted acoustic signal information data to the acoustic
reproduction output device 30 via the terminal 14 (step S45). Thereafter, the same processing is
performed in the sound reproduction output devices 30 and 40 (steps S46 and S47).
As a result of the above, the channel control unit 12 of the sound reproduction output device 10
causes the internal speaker 13 to output the sound corresponding to the extracted sound signal
(step S 48). In this operation example, a sound corresponding to the sound signal for the C
channel is output from the internal speaker 13. Similarly, in the same manner, the channel
control unit 12 of the sound reproduction output devices 20, 30, 40, and 50 controls the sound
corresponding to the sound signal for the FR channel, the sound corresponding to the sound
signal for the FL channel, and the RR channel. The sound corresponding to the sound signal is
output from the built-in speaker 13 corresponding to the sound signal for the RL channel (steps
S49 to S52). Here, the operations involved in the switching of the playback device and the
delayed playback are not described as they are processed by the same concept as the concept
described in each operation example of the first embodiment. [2.3] Modification of Second
Embodiment In the above-described second embodiment, the case where the number of
connected sound reproduction output devices is set to five has been described. The number of
connected devices is not limited to five. For example, the number of connected sound
reproduction output devices may be set to three. In this case, set the number of connected
settings 174 stored in each sound reproduction output device to 3 and set the channel type
172 to C , R , and L . Just do it. [3] Effects of the Embodiment As described above, by

connecting a plurality of sound reproduction output devices, the sound corresponding to the
sound signal reproduced in one sound reproduction output device is connected to another. It
becomes possible to output from the speaker of the sound reproduction output device. Further,
when the sound signal reproduced by one sound reproduction output device corresponds to a
plurality of channels, the sound output corresponding to each channel is assigned to each sound
reproduction output device. It is possible to construct a new stereo system. In addition, the sound
to be output in the other sound reproduction output device can be output simultaneously with
the sound output in one sound reproduction output device, and it is also possible to be delayed
and output little by little. Therefore, variations in outputting sound can be increased. [4]
Modification of the embodiment In the above-described embodiments, when connecting each
sound reproduction output device, although connected using an output / input code, each sound
reproduction output The method of connecting the devices is not limited to this embodiment.
For example, the sound reproduction output device may be provided with an interface for
wireless connection and wirelessly connected. Further, in each of the embodiments described
above, the sound reproduction output device is configured of one speaker, but the configuration
of the speaker is not limited to this embodiment. For example, two or more speakers may be
provided to output stereo sound. In each of the above-described embodiments, the plug of the
output / input cord is inserted into the terminal 14, but it is not necessary to be one terminal,
and the output terminal and the input terminal It may be provided separately. Note that the
method for realizing various functions of the sound reproduction output apparatus according to
each embodiment described above stores a program for executing various functions performed
in the sound reproduction output apparatus in the sound reproduction output apparatus in
advance. Is not limited to the case of For example, the program may be installed and read after
being read from a recording medium storing the program, or may be installed and realized after
