PORTABLE TERMINAL, PROGRAM THEREOF AND CALLED VOLUME CONTROL METHOD
[0001]
The present invention relates to a portable terminal that outputs an incoming call at an optimal
volume according to the connection state of a headphone to a terminal body, a program thereof,
and a control method of an incoming call sound volume.
[0002]
Mobile terminals represented by mobile phones have made it possible to easily obtain music,
games, videos, and other content via the Internet, and they can now be enjoyed anywhere.
When using an application that outputs voice, most users listen to music or the like using a
portable terminal equipped with headphones so as not to be a nuisance of the surroundings in a
public place such as a train. Therefore, recently, damage to the human body, such as hearing loss,
which impairs the health of the ear by listening to a loud volume of sound with headphones, is

volume, you will hear a louder volume with headphones than you hear with the speakers, and it
will impair the health of the ear, and conversely, it will be best with headphones After setting the
volume, if you do not adjust the volume in the same way, you may miss the incoming voice
because you will hear a smaller volume on the speaker than you would listen on the headphones.
In addition, when the portable terminal is housed in a pocket or a bag with the headphone
connected to the portable terminal, the incoming voice is output from the headphone, so that
there is also a problem that the incoming voice is missed.
[0007]

music, and an output from data such as incoming voice and music There is an incoming call, an
audio generation unit 103 that generates a signal, a volume adjustment unit 104 that amplifies
or attenuates an output signal of the audio generation unit 104, a headphone detection unit 105
that detects connection of headphones to a terminal body, A wireless unit 106 for generating an
incoming call signal, a speaker 107 for outputting incoming voice and music, etc., and a
headphone 110 connected to a portable terminal for outputting incoming voice and music etc.
[0016]
Next, the operation of the portable terminal shown in FIG. 1 will be described with reference also
to the flowchart of FIG.
The control unit 101 continues to detect the incoming signal until there is an incoming call (step
S201: No), and when there is an incoming call and detects the incoming signal from the wireless
unit 106 (step S201: Yes), the control unit 101 detects the headphone detection unit 105. To
detect the detection signal (step S202).
When the headphone 110 is not connected to the terminal body 100 (step S202: No), the control
unit 101 sets the volume of the voice generation unit 103 and the speaker to the data of the
incoming call voice and the first volume previously set in the memory 102. It is output to the
adjustment unit 104.
The output signal generated by the voice generation unit 103 is adjusted in volume by the
volume adjustment unit 104 and transmitted to the speaker, whereby the incoming call voice is
output from the speaker 107 at the first volume (steps S205 and 206).
Similarly, when the headphone 110 is connected to the terminal body 100 (step S202: Yes), the
control unit 101 similarly sounds the incoming call sound and the second volume data lower
than the first volume, which are set in the memory 102 in advance. It is output to the generation
unit 103 and the volume control unit 104 of the headphone 110. The output signal generated by
the sound generation unit 103 is adjusted in volume by the volume adjustment unit 104 and
transmitted to the speaker, whereby the incoming call sound is output from the headphone 110
at the second volume (steps S203 and S204).

[0017]
As described above, the portable terminal according to this embodiment can individually control
the volume output to the headphone 110 and the speaker 107 according to the presence or
absence of the connection of the headphone 110. That is, step S202 for detecting the presence /
absence of connection of the headphone 110 and setting steps S205 and S203 for the first and
second sound volumes can be called headphone connection detection means and volume
adjustment means, respectively.
[0018]
Hereinafter, a second embodiment of the present invention will be described with reference to
FIG. 1 and FIG. This embodiment corresponds to the first embodiment to which step S210 is
added as music output detection means, that is, means for detecting whether or not music by a
music application is in an output state. The processing up to the detection of the incoming signal
is the same as that of the first embodiment, so the processing is omitted and the processing after
the detection will be described. When the headphone 110 is not connected to the terminal body
100 (step S202: No), the control unit 101 sets the volume of the voice generation unit 103 and
the speaker to the data of the incoming call voice and the first volume previously set in the
memory 102. It is output to the adjustment unit 104. The output signal generated by the voice
generation unit 103 is adjusted in volume by the volume adjustment unit 104 and transmitted to
the speaker, whereby the incoming call voice is output from the speaker 107 at the first volume
(steps S205 and 206). When the headphone 110 is connected to the terminal main body 100,
the incoming call sound is output from the speaker 107 at the first volume even when music or
the like is not output (steps S205 and 206). On the other hand, when music or the like is output,
that is, when music or the like is output by the music application, when the control unit 101
detects it from the memory 102, the incoming call sound is output from the headphone 110 at
the second volume. (Steps S203 and 204).
[0019]
The block of S201 which is a headphone connection detection means and the block of S202
which is a music output means may be reversed. Further, in the above embodiment, when the
headphone 110 is connected to the terminal main body 100, it may be configured such that the
incoming call sound individually set is output from both the headphone 110 and the speaker
107. In this configuration, even if music or the like is output and the headphone 110 is not worn

on the ear, that is, even if the headphone 110 is not worn on the ear but you forgot to stop the
music etc. Furthermore, it has the advantage of reducing the opportunity to miss an incoming
call.
[0020]
The operations according to the flowcharts shown in FIGS. 2 and 3 are generally executed by a
program stored in a computer readable recording medium, but may be executed by hardware
circuitry. In addition to the electrical connection, the headphones 110 may be wireless
headphones using infrared rays as long as they can communicate with the terminal body 100.
Further, the incoming call voice and the music include those stored in advance in the memory
102, and those received from the network such as the Internet and stored in the memory 102.
Incoming calls also include incoming e-mails, chats, etc. received through the network.
[0021]
The above-described embodiments are merely examples of preferred embodiments of the present
invention, and the present invention can be modified in various ways without departing from the
scope of the invention.
[0022]
In the embodiment described above, the mobile phone has been described, but the method for
controlling the incoming call sound volume according to the present invention can be applied to
a portable terminal such as a portable personal computer and a PDA (Personal Digital Assistant)
that can communicate through a network. it can.
