Configuration of Embodiment The network 1 is a communication line such as the Internet or a
LAN, and as shown in FIG. 1, a plurality of communication terminals are connected. In the
present embodiment, a personal computer 10 is connected as a communication terminal that
performs voice communication. Further, connected to the network 1 is a partner apparatus 2
which is a communication terminal on the partner side which performs voice communication
with the personal computer 10. The counterpart apparatus 2 is equipped with the same
communication software as that installed in the personal computer 10. Further, the personal
computer 10 is connected by an audio adapter 20 to a headset 30 which is an audio device.
[0014]
As shown in FIG. 2, the personal computer 10 mainly includes a CUP 11, a sound card 12, a

microphone It is called a signal.
[0017]
As shown in FIG. 2, the audio adapter 20 mainly includes an input terminal 21, an adapter-side
headphone terminal 22, an output terminal 23, an adapter-side microphone terminal 24, and a
conducting wire 25. The input terminal 21 is a plug connected to the PC-side headphone
terminal 14 to input an audio signal. The adapter-side headphone terminal 22 is a terminal
connected to the input terminal 21 and connectable to an external speaker.
[0018]
The output terminal 23 is a plug connected to the PC side microphone terminal 15 to output an
audio signal. The adapter-side microphone terminal 24 is a terminal connected to the output
terminal 23 and connectable to an external microphone. The conductor 25 electrically connects
the input terminal 21 and the output terminal 23 inside the audio adapter 20. In the present
embodiment, the output terminal 23 is directly connected to the input terminal 21 by the
conducting wire 25 without interposing an electric element such as a resistor.
[0019]
The headset 30 is a communication device in which a headphone having a speaker unit and a
microphone are integrated. The headset input terminal 31 is a plug that is connected to the
adapter-side headphone terminal 22 of the audio adapter 20 and inputs an audio signal from the
audio adapter 20. Thus, the headset 30 outputs a sound corresponding to the audio signal from
the speaker unit.
[0020]
The headset output terminal 32 is a plug that is connected to the adapter-side microphone
terminal 24 of the audio adapter 20 and outputs an audio signal to the audio adapter 20. That is,

communication device having a separate configuration such as an earphone and a microphone.
[0021]
With such a configuration, the personal computer 10 can perform voice communication with the
partner apparatus 2 via the network 1. The personal computer 10 is operated by a generalpurpose operating system. In the present embodiment, the operating system of the personal
computer 10 is Windows (registered trademark) Vista or Windows (registered trademark) 7.
Furthermore, the personal computer 10 and the partner apparatus 2 perform half duplex voice
communication in which calls can be alternately made to one side by communication software
installed in each. In the present embodiment, the above communication software is HAHOO!
(Registered trademark) is a messenger.
[0022]
(Operation of Audio Adapter 20) Next, the operation of the audio adapter 20 in voice
communication between the personal computer 10 and the partner apparatus 2 will be
described. First, when audio data is transmitted from the partner apparatus 2, the personal
computer 10 inputs the audio data via the network 1. Communication software operated by the
CPU 11 converts digital audio data into an analog audio signal by the sound card 12 and the
CODEC 13 and outputs the analog audio signal from the PC-side headphone terminal 14.
[0023]
The audio adapter 20 inputs an audio signal from the input terminal 21 connected to the PC-side
headphone terminal 14. Then, the audio signal is output from the adapter-side headphone
terminal 22 connected to the input terminal 21 to the headset 30, and is converted into sound in
the speaker unit of the headset 30. As a result, the voice of the other party who operates the
opposite device 2 can be heard.
[0024]
Also, inside the audio adapter 20, the input terminal 21 and the output terminal 23 are
10-05-2019
7
connected by the conducting wire 25. Therefore, the input audio signal is output to the PC side
microphone terminal 15 to which the output terminal 23 is connected. However, since the
communication software of the present embodiment performs half duplex voice communication,
no voice signal is output from the personal computer 10 to the partner apparatus 2.
[0025]
Subsequently, the case of transmitting an audio signal from the personal computer 10 will be
described. The headset 30 outputs an analog audio signal corresponding to the voice from the
microphone from the headset output terminal 32. The audio adapter 20 inputs an audio signal
from the adapter-side microphone terminal 24 to which the headset output terminal 32 is
connected. The output terminal 23 connected to the adapter microphone terminal 24 outputs the
input audio signal to the PC microphone terminal 15.
[0026]
Further, in the audio adapter 20, the output terminal 23 is connected to the input terminal 21 by
the conducting wire 25. Therefore, the output terminal 23 synthesizes the audio signal input to
the audio adapter 20 with the audio signal from the headset 30 and outputs the synthesized
audio signal to the PC side microphone terminal 15. The communication software converts an
analog voice signal input from the PC side microphone terminal 15 and combined with the audio
signal into digital voice data by the sound card 12 and the CODEC 13. Then, the personal
computer 10 outputs the voice data to the partner apparatus 2 via the network 1. By performing
the same process as the personal computer 10, the partner device 2 outputs voice data as a
sound through an external speaker, and the voice of the other party can be heard.
[0027]
Further, as described above, when the personal computer 10 is on the transmission side, the
audio data output to the partner apparatus 2 is obtained by converting an audio signal in which
the audio signal is synthesized into digital. Here, since the communication software performs half
duplex voice communication, when in the transmission state, the audio data to be synthesized
does not include the audio data output from the partner apparatus 2. The audio signal includes a
signal output by the personal computer 10 by processing not related to the communication
software, and a control signal output when the communication software is in the transmission
10-05-2019
8
state.
[0028]
(Effect of Audio Adapter 20) According to the above configuration, the audio adapter 20 receives
an audio signal output from the personal computer 10 at the PC microphone terminal 15. Then,
the communication software transmits a synthetic signal of the voice signal and the audio signal
of the microphone of the headset 30 to the other party in the transmission state of the half
duplex voice communication. In the configuration that enables such half-duplex voice
communication, the influence of noise can be reduced, and the voice quality of the voice by the
synthesized signal transmitted to the other party can be improved as compared to the
conventional case. Therefore, by connecting an audio device to the personal computer 10 by the
audio adapter 20 of the present invention, the sound quality of the call can be improved.
[0029]
The operating system of the personal computer 10 is Windows (registered trademark) Vista or
Windows (registered trademark) 7. Furthermore, the communication software installed in the
personal computer 10 is YAHOO! (Registered trademark) is a messenger. When half duplex voice
communication is performed in a communication environment including such a configuration, a
voice signal may not be transmitted to the other party. Therefore, in the above communication
environment, when an audio signal is synthesized with an audio signal by the audio adapter 20 of
the present invention, the audio signal can be transmitted to the other party.
[0030]
Furthermore, the output terminal 23 of the audio adapter 20 is directly connected to the input
terminal 21 by a conducting wire without an electrical element. With such a configuration, the
configuration can be simplified, noise can be prevented from being mixed, and the sound quality
of the call can be improved.
