DESCRIPTION JPH09274557
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an
information processing method and apparatus, and more particularly to a portable computer
having a speaker system.
[0002]
2. Description of the Related Art In recent years, with the progress of technology, computers
have been rapidly developed, and models having so-called multimedia functions such as
functions related to images and audio are becoming mainstream. Such a tendency is also applied
to a portable computer called a notebook computer, and in particular, there are many notebook
computers equipped with two speakers and capable of stereo reproduction to improve the audio
function. However, devices that place emphasis on portability, such as laptop computers, are
required to have high functionality and high density. Therefore, it is difficult to provide a largeaperture speaker that is advantageous for bass reproduction and to secure a sufficient space on
the back of the speaker that is necessary to fully demonstrate the performance of the speaker,
and such a space is likely to occur in design. However, priority has been given to spending on
equipment and downsizing of the latest devices. Therefore, in the past, the performance of the
built-in speaker of the notebook personal computer has been reduced to some extent, and a
separate speaker box is used to reproduce a good sound, or a separate body used to extend the
function of the notebook personal computer A method has been adopted in which a speaker is
mounted in a docking station (having a relatively large space) and switching is performed with a
speaker built in the notebook computer.

[0003]
In addition, such a docking station is assumed to be equipped with various input / output
devices. Among them, a docking station which incorporates an amplifier and equipped with a CDROM drive and a speaker has been considered. Such a docking station has a dedicated volume as
with a laptop computer, so that it is possible to play CD music alone as a CD player without
docking with the laptop computer.
[0004]
Also, laptop computers are often equipped with a volume for volume control, and the user can
adjust the volume from the speaker (or headphones) by moving this volume.
[0005]
[Problems to be solved by the invention] In the conventional method, when using the external
speaker or when using the speaker of the docking station, it is simply switching between the
built-in speaker and the external speaker, and killing the built-in speaker of the notebook
computer body is wasteful Not only that, but there was also the problem that only the
performance of one of the speakers could be used.
[0006]
Also, if you dock the notebook computer with a docking station that has volumes separately as
described above, there will be two volumes for volume control, and if you want both volumes to
work simultaneously, When work becomes complicated and one of the volumes is invalidated,
there is a problem that it is difficult for anyone other than the regular user to know which
volume is effective.
[0007]
In addition, when the laptop computer's sound is output from the docking station's speaker after
docking while docking (hot docking) while the laptop is in operation, if the docking station's
volume level is too high or too low, the user There was also the issue of being confused.

DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) A detailed description of
the embodiment of the present invention will be given below with reference to the drawings.
09-05-2019

[0027]
FIG. 1 is an electrical block diagram of an information processing apparatus embodying the
present invention, and reference numeral 1 is a main body of a notebook computer.
The main body 1 includes a control circuit 2 which controls the CD-ROM drive 4 and the like, and
sends an ON / OFF signal to the switch controller 7 by a signal from the docking sensor 3.
The switch controller 7 connects the left switch 9 and the right switch 10 to any of the terminals
A, B, C, D by this signal.
The control circuit 2 controls various processes described below according to a control program
stored in a memory (not shown).
The CD-ROM drive 4 is incorporated in the main body 1 as an example of an audio output device
of the present apparatus, reads data from the mounted CD-ROM, and is controlled from the CD
audio output terminal 8 under control of the control circuit 2. An audio signal is output to the
audio circuit 5.
This audio signal is input to the audio circuit 5 from the CD audio input terminal 12, amplified by
the audio circuit 5, and output from the audio output terminal 13.
The amplified audio signal may be input to the audio terminal 14 of a well-known network circuit
11 composed of a coil and a capacitor, as it is when the built-in speaker 6 is made to sound as it
is.
When the amplified audio signal is input to the network circuit 11, it is divided into a low
frequency audio signal (approximately 1 kHz or less) and a middle high frequency audio signal
(approximately 1 kHz to approximately 20 kHz), and the low frequency audio signal is output to
the bass output terminal 16 The mid-high range audio signal is output from the mid-high range
sound output terminal 15.
09-05-2019
6
At this time, the mid-high range audio signal causes the built-in speaker 6 to ring, and the lowrange audio signal causes an external speaker connected to the external audio output terminal
17 provided in the main body 1 to ring.
In this embodiment, the station speaker 20 provided in the docking station 19 which is combined
with the main body 1 and extends the function of the main body 1 is the external speaker, and
the external audio input terminal 18 provided in the docking station 19 and the main body The
external audio output terminal 17 of 1 is connected, and the mid-high frequency audio signal
input to the docking station 19 causes the station speaker 20 to ring.
[0028]
An outline of the appearance of the apparatus of this embodiment configured as described above
is shown in FIG.
As shown in FIG. 2, when the main body 1 of the notebook computer and the docking station 19
are separated, that is, when the main body 1 is used alone, the control circuit 2 sets the docking
sensor 3 in the OFF state. It recognizes that it is turned on, and sends an OFF signal to the switch
controller 7.
This state is a state in which the sensor protrusion 21 provided in the docking station 19 in FIG.
2 does not push in the docking sensor 3 in the main body 1 which is a switch (a state in which
the switch is not turned on).
While receiving the OFF signal, the switch controller 7 connects the left switch 9 and the right
switch 10 to the terminal A and the terminal C, respectively.
Then, the audio signal output from the CD-ROM drive 4 and amplified by the audio circuit 13
causes only the built-in speaker 6 to ring directly without going to the network circuit 11.
In this case, all audio signals output from the CD-ROM drive 4 are output by the built-in speaker
09-05-2019
7
6.
Here, the built-in speaker 6 is designed to output middle to high frequency sound (approximately
1 kHz or more and 20 kHz or less) well depending on the aperture and the surrounding
configuration.
This is because it is not possible to use a speaker with a large aperture because of the size
restrictions of the laptop computer, and it is difficult to get low temperature from the beginning,
and it is necessary to use the network conference etc. as the minimum necessary condition when
using it alone. In consideration of the main part (about 1 to 8 kHz) of the human voice band.
[0029]
Further, as shown in FIG. 3, when the main body 1 and the docking station 19 are coupled, the
external output terminal 17 and the external input terminal 18 are connected, and the control
circuit 2 turns on the docking sensor 3 And sends an ON signal to the switch controller 7.
This state is a state in which the sensor projection 21 provided in the docking station 19 in FIG. 2
pushes the docking sensor 3 in the main body 1 as a switch (a state in which the switch is on).
While receiving the ON signal, the switch controller 7 connects the left switch 9 and the right
switch 10 to the terminal B and the terminal D, respectively.
Then, the audio signal output from the CD-ROM drive 4 and amplified by the audio circuit 13
proceeds to the network circuit 11, and the middle to high frequency audio signal causes the
built-in speaker 6 to ring and the low frequency audio signal to ring the station speaker 20 It will
That is, the audio signal output from the CD-ROM drive 4 is divided into two by the network
circuit 11 and transferred to two speakers.
Here, in the station speaker 20, low frequency sound (approximately 1 kHz or less) is often

output due to the aperture and the surrounding configuration.
This is because the docking station is less limited in size, and can be equipped with a largeaperture speaker that can easily output bass, and can secure space behind the speaker.
[0030]
With this configuration, the present embodiment combines the notebook PC with the docking
station, and controls the transfer of the audio signal, thereby allowing the PC to output a 2-way
speaker system that can often output audio from low to high frequencies. Is also intended to be
realized.
[0031]
Second Embodiment In the above-described first embodiment, a so-called docking station is
equipped with a bass speaker, and a two-way speaker system is constructed by coupling a laptop
computer and a docking station, but the bass speaker is particularly incorporated in the docking
station It does not have to be, it may be just an external speaker.
This situation is shown as a perspective view in FIG.
Reference numeral 22 is an external speaker. At that time, the difference from the first
embodiment is that a sensor corresponding to the docking sensor 3 of the first embodiment is
provided in the vicinity of the external sound output terminal 17 or in the terminal itself (not
shown) and an external speaker is connected. When this is detected immediately, an audio signal
may be input to the network circuit 11 and a low frequency audio signal may be input to the
external speaker.
[0032]
Also, from the above explanation, it is clear that constructing a three-way or more speaker
system can be easily realized by dividing the audio signal into three or more frequency bands
and increasing the number of speakers according to the frequency band. is there.
[0033]
09-05-2019

Of course, in both of the first and second embodiments, the means for causing the notebook PC
main body to detect the connection of the docking station or the external speaker may be
manual, or the means for generating the audio signal is not limited to the CD-ROM drive, etc.
Needless to say.
[0034]
(Embodiment 3) A detailed description of an information processing apparatus embodying the
present invention will be given below with reference to the drawings.
[0035]
FIG. 6 is a schematic view of the external appearance of the present apparatus. Reference
numeral 1 denotes a notebook computer, and 102 denotes a docking station connectable to the
notebook computer 1.
The notebook computer 1 includes a stereo speaker 110 and a mechanical volume 111 (very
common, well-known variable resistor), incorporates an amplifier circuit (not shown), and is a
sound source from an output device equipped, for example, a hard disk Audio from a floppy disk
or the like can be output alone from the speaker 110, and the operator can freely adjust the
volume output from the speaker 110 by means of the volume 111.
The docking station 102 includes a CD-ROM drive 103, a dock-side stereo speaker 105, a display
panel 106, a software control volume 107, an operation panel 108, and incorporates an amplifier
circuit (not shown). From 105, music CDs can be played independently.
In addition, the docking station 102 is provided with a docking connector 109, and can be
connected with a connector (not shown) provided also in the notebook computer 1 to be
electrically connected and integrated as shown in FIG. .
[0036]
FIGS. 5, 8, 9 and 10 show an electric block diagram of the present apparatus having such a
configuration. FIG. 5 is an electrical block diagram of FIG. 6 when the notebook computer 1 and
09-05-2019
10
the docking station 102 are in the separated state, and the contacts 114, 115, 116 are not
connected. Reference numerals 112, 113, 117, 118, and 119 are switches. Further, the contacts
114, 115, 116 electrically connect the notebook computer 1 and the docking station 102 at the
time of docking (not connected in the state of FIG. 1). In the state of FIG. 5 and FIG. 6, the
notebook computer 1 and the docking station 102 respectively independently sound the sound
from the sound source by the respective speakers, and the volume can be freely adjusted by the
operator by the respective volumes 111 and 107. Also, at this time, the switches 112, 113, 117
and 119 are always closed.
[0037]
When the notebook computer 1 and the docking station 102 are docked by the docking
connector 109, all the contacts 114 115 116 are connected as shown in FIG. When the
connection of the docking connector 109 is detected, the switch 113 is opened, and all the audio
signals are not input to the mechanical volume 111, but are always input to the soft volume 107.
At this time, a signal indicating the resistance value of the mechanical volume 111 is input to the
soft volume 107 through the contact point 115, and the soft volume 107 changes the
amplification factor setting value of the amplifier circuit according to the resistance value of the
mechanical volume 111. The amplifier circuit amplification factor setting value by this soft
volume is a value that results in the same volume as the volume output through the mechanical
volume when the speaker used is the stereo speaker 110, and in the case of the dog side stereo
speaker 105 The amplifier circuit amplification factor is set such that the same volume as the
volume output from the stereo speaker 110 is output in consideration of the efficiency of the
speaker 105. Therefore, the same volume as the volume of the notebook computer 1 (stereo
speaker 110) alone, which has been adjusted by the mechanical volume 111 up to now, is output
from either of the speakers after docking, which may cause confusion to the user. Absent.
Furthermore, in the docked state, as shown in FIG. 7, the volume guard 104 provided in the
docking station 102 is configured to hide the mechanical volume 111 of the notebook computer
1 so that the user does not touch it. The adjustment is integrated into the soft volume 107. The
switches 112 and 117 are switches for selecting which source on the notebook computer 1 side
or the docking station 102 side to use as a sound source, which is displayed on the display by the
application of the notebook computer 1 and can be switched by the user It can be done. The
switches 118 and 119 are switches for selecting which speaker to use, and are displayed on the
display by the application of the notebook computer 1 like the switches 112 and 117 so that the
user can switch. In this speaker switching application, when the user selects the speaker (stereo
speaker 110) on the notebook computer 1 side, as shown in FIG. 8, the switch 118 is opened and
the switch 119 is closed.
09-05-2019
11
When the speaker on the docking station 102 side (the dock side stereo speaker 105) is selected,
as shown in FIG. 9, the switch 118 is closed and the switch 119 is opened. As a result, the
switches 118 and 119 are both closed and audio is output from the four speakers.
[0038]
Also at this time, the soft volume sets the amplification circuit amplification factor of each
amplifier so that the sound output from the four speakers becomes almost the same as the
previous output volume.
[0039]
Although the above description assumes that both the notebook computer 1 and the docking
station 102 stop and dock the audio output application, one of the notebook computer 1 and the
docking station 102 is playing back some sound source. When both sides are docked, it is of
course possible to display on the display an operation panel for controlling the sound source
being reproduced by the application of the notebook computer 1 while continuing the sound
reproduction.
[0040]
In the first embodiment, in the simultaneous output of the speaker of the notebook computer 1
and the speaker of the docking station 102 shown in FIG. 10, the reproduction frequency
characteristics of the respective speakers are different as described in the first and second
embodiments. At least by dividing an audio signal into an audio signal of a frequency band
through a well-known network circuit consisting of a coil and a capacitor, and distributing an
audio signal of a frequency band suitable for each speaker so that the audio is output from the
speaker It is possible to construct a 2-way speaker system and provide good quality output
sound.
[0041]
In the above description, the volume control of the notebook computer 1 is performed by the
mechanical volume, but of course this may be a soft volume controlled by software.
In this case, the volume of the notebook computer alone is adjusted using the keyboard of the
notebook computer 1 or the icon on the display.
09-05-2019
12
Although the volume control from the keyboard of the laptop computer is basically disabled
during docking, the system can be configured to use the volume on the docking station 102 side,
but since the note side is also a soft volume control It is also possible to provide a system that
communicates amplifier circuit amplification factors set with each other, and enables volume
control from the notebook computer 1 side and the docking station 102 side.
[0042]
As described above, according to the present invention, when the notebook computer and the
speaker system are combined, the divided audio signal causes the speaker system of the device
body and the external speaker system to ring simultaneously. This has the effect of improving the
sound quality of the output voice.
[0043]
As described above, according to the present invention, when the notebook computer and the
docking station are separated, each can independently adjust the sound output and the volume,
so that the function as a single unit is not wasted. When docked, disabling one of the volumes
and adjusting the volume with only one volume has the effect of eliminating the complexity of
volume control and the change in volume during docking.
[0044]
In addition, by outputting sound from at least one of the two speakers, it is possible to select a
speaker according to the user's preference and to construct a two-way speaker system to
improve the sound quality of the output sound. There is an effect that docking can be performed
while audio output is continued, and the operation can be performed on the display of the
notebook computer.
