[0025]
FIG. 2 is a flow chart for explaining the operation of the sound adjustment apparatus, and in the
figure, ST indicates each step of the flow.
[0026]
First, in step ST1, when the base station sends a signal indicating an incoming call to the mobile
phone, the mobile phone transmits a signal for informing the base station that reception is
possible.
[0027]
During this exchange with the base station, the volume of ambient noise of the mobile phone is
measured using the microphone 13 built in the mobile phone (step ST2).
[0028]
In step ST3, the mobile phone determines the call volume set in advance in the mobile phone
according to the measured volume, and causes the ringer unit (sounder) 14 to ring the ring tone

in step ST4.
[0029]
The user listens to this ringing sound and presses and receives a key button as a receiving
operation (step ST5).
[0030]
As described above, the sound adjustment apparatus according to the first embodiment measures
the noise around the user after an incoming call, sets the ringing tone level based on the
measured noise signal, and sets the ringing tone. As it is made to ring at a level, it is possible to
specify the ringing volume according to the volume of ambient noise (noise), so the ringing
volume in a quiet environment (for example, a conference room, library, etc.) should be
performed with a small volume It becomes possible, and it is possible to receive an incoming call
without disturbing the surrounding people.
[0031]
Also, in a mobile phone with a built-in vibrator, it is possible to activate and call this vibrator
when noise is below a certain level, and it is possible for the user (user) to operate without
setting this mode. Become.
On the contrary, in a situation where ambient noise is extremely large, it becomes possible to
make the ringing volume ring at a high level from the beginning, resulting in fewer missed calls.
[0032]
The sound adjustment apparatus according to the second embodiment of the present invention
enables the user to talk at a comfortable reception volume immediately after an incoming call.
In addition, since the hardware-like structure of the sound adjustment apparatus which concerns
on this embodiment is the same as that of FIG. 1, description of this part is abbreviate | omitted.
10-04-2019

[0033]
FIG. 3 is a flow chart for explaining the operation of the sound adjustment apparatus according
to the second embodiment, and the steps performing the same processing as FIG. 2 are given the
same reference numerals.
[0034]
First, in step ST1, when the base station sends a signal indicating an incoming call to the mobile
phone, the mobile phone transmits a signal for informing the base station that reception is
possible.
[0035]
During this exchange with the base station, the volume of ambient noise of the mobile phone is
measured using the microphone 13 built in the mobile phone (step ST2).
[0036]
Thus, at the time of an incoming call, the ambient noise of the location where the mobile phone is
used is measured.
[0037]
Next, in steps ST4 and ST5, the procedures of ringing and reception operation (incoming call
operation) are performed.
That is, the mobile phone determines the call volume set in advance in the mobile phone
according to the measured volume, and causes the ringer unit 14 incorporated in step ST4 to
ring a ring tone, and the key button is pressed in step ST5. Press to perform a reception
operation.
[0038]
During this operation, the volume is adjusted to the volume level of the receiver (speaker) of the
portable telephone registered in advance in the portable telephone according to the ambient
noise amount in step ST6.
10-04-2019

The user talks with the other party with this volume-controlled handset (step ST7).
[0039]
As described above, the sound adjustment apparatus according to the second embodiment
measures the noise around the user after an incoming call, sets the volume of the handset of the
portable terminal based on the measured noise signal, and is set. The volume of the handset is
adjusted at the same volume, so the initial volume of the handset can be specified according to
the volume of the ambient noise, so even if the ambient noise is large, the other party's received
volume can be heard loudly from the start of talk It becomes possible to hear the other party's
confirmation and voice clearly.
For the same reason, it is possible to obtain an effect that the user does not have to adjust the
volume after the talk.
[0040]
Also, in a quiet environment, it is possible to have an initial conversation without an unusually
loud voice of the other party.
[0041]
The sound adjustment apparatus according to the third embodiment of the present invention is
limited to the in-vehicle hands-free kit of the portable telephone, and provides a function of
automatically performing the volume control of the external speaker in response to the ambient
noise.
Note that the hardware configuration of the sound adjustment apparatus according to the
present embodiment is the same as that of FIG.
[0042]
FIG. 4 is a flow chart for explaining the operation of the sound adjustment apparatus according
10-04-2019
8
to the third embodiment, and the steps in which the same processing as in FIG. 2 and FIG. 3 is
given the same reference numerals.
[0043]
After the incoming signal is input to the mobile phone connected to the in-vehicle hands-free kit
(step ST1), the ambient noise volume measurement described in the first embodiment is
performed during the connection operation with the base station side. Is implemented using the
external mounting microphone of the in-vehicle hands-free kit (step ST2).
Next, in step ST3, the ringing volume from the external speaker is determined based on the
measurement result, and in step ST4, the ringing tone is produced by the external speaker.
[0044]
During the ringing of the ringing tone (between sounds), the ambient noise volume is further
measured in step ST2, and the reception volume of the external speaker is adjusted in step ST6.
[0045]
Here, in the case where the reception operation is performed in step ST5 and the intersection is
entered (step ST7), it is possible to hear the voice of the other party whose volume is adjusted
from the beginning.
[0046]
Also, as shown in the latter part of FIG. 4, the ambient noise level is measured at regular intervals
(when the user is not speaking) even during talk, and the volume of the external speaker is
checked according to the ambient noise level. Automatic adjustment can be performed during
talk time.
[0047]
Furthermore, the external speaker volume can also be adjusted when a certain amount of volume
level difference occurs with the ambient noise amount initially measured as a reference value.
[0048]
10-04-2019

As described above, the sound adjustment apparatus according to the third embodiment detects
the ambient noise amount at fixed time intervals or every predetermined level change by the onvehicle microphone during a call, and is based on the detected noise signal. The volume of the invehicle external speaker is adjusted with the set volume, so the volume adjustment of the invehicle hands-free kit external speaker is automatically performed according to the ambient
noise amount. The following effects can be expected by adjusting.
[0049]
That is, since the user can recognize the telephone ringing tone with the volume corresponding
to the ambient noise, natural reception can be performed, and operation errors during driving
can be reduced as much as possible.
[0050]
In addition, since the other party's call sound is adjusted according to the ambient noise level, the
user does not have to adjust the volume during the call, and it is possible to talk on the phone
without the driving operation being neglected.
[0051]
The sound adjustment apparatus according to the fourth embodiment of the present invention
measures the transmission sound volume level on the side of using the mobile phone, and
determines the reception sound volume according to the volume.
Note that the hardware configuration of the sound adjustment apparatus according to the
present embodiment is the same as that of FIG.
[0052]
FIG. 5 is a flow chart for explaining the operation of the sound adjustment apparatus according
to the fourth embodiment, and the same steps as those in FIG. 2 and FIG. Do.
[0053]
When the user uses the mobile phone (or when the in-vehicle hands-free kit is installed), after
entering the communication mode in step ST7, in step ST8, the user's speech volume on the builtin microphone (or external microphone) In step ST6, the reception volume according to the
10-04-2019
10
volume is adjusted, and in the subsequent step ST7, the voice of the other party is made to flow
from the receiver.
[0054]
As described above, the sound adjustment apparatus according to the fourth embodiment
measures the transmission sound volume and controls the output of the receiver based on the
measured sound volume. The following effects can be expected by being able to set the reception
volume to match.
[0055]
That is, the user usually talks with the other party by enlarging the transmission sound (voice)
when the other party's voice can not be heard well due to ambient noise or the like.
In this case, the user can make a natural call by automatically increasing the voice of the other
party (listening voice) when the voice of the user becomes louder.
[0056]
Further, even when the user is deaf, the transmitted sound becomes large and the received sound
also becomes large, so that the user can make a comfortable call without adjusting the volume
and the like.
[0057]
The sound adjustment apparatus according to the fifth embodiment of the present invention
provides a function capable of measuring ambient noise on the side of the portable telephone in
advance and reducing noise at the time of talk.
Note that the hardware configuration of the sound adjustment apparatus according to the
present embodiment is the same as that of FIG.
[0058]
10-04-2019

FIG. 6 is a flow chart for explaining the operation of the sound adjustment apparatus according
to the fifth embodiment, and the steps carrying out the same processing as in FIG. 2 and FIG. Do.
[0059]
First, in step ST11, an incoming signal is received from the base station side, and while the user
performs a reception operation, a noise pattern around the use is measured using the built-in
microphone of the mobile phone used by the user.
[0060]
Next, the ambient noise pattern measured in step ST12 is digitally processed to generate an
antiphase pattern of the pattern.
[0061]
In addition, when the user is in a call state and transmits voice, surrounding noise is also
simultaneously transmitted (steps ST13 to ST15).
[0062]
In step ST16, a signal obtained by subjecting these complex sounds to digital audio processing in
the apparatus and data in which ambient noise has been digitally processed into an antiphase
pattern are mixed, and audio signal processing is performed to remove only ambient noise.
[0063]
After being mixed, only the user's voice data remains.
This is sent to the other party (step ST17).
[0064]
In step ST18, on the other side, the received signal is voice-processed on the other side, and in
step ST19, it becomes possible to hear from the receiver (speaker) as a reproduced voice with
reduced ambient noise.
10-04-2019
12
[0065]
As described above, the acoustic adjustment device according to the fifth embodiment measures
the feature pattern of the ambient noise, generates a pattern having the opposite phase to the
measured ambient noise, and generates the inverse phase pattern and the input sound. Since
voice signal processing is performed to reduce ambient noise by combining, it is possible to
reduce ambient noise using the mobile phone, and it is possible to convey only clear voice to the
other party.
Further, by using this method during a call, noise reduction with higher accuracy can be
achieved.
[0066]
The sound adjustment apparatus according to the sixth embodiment of the present invention
realizes a call in which ambient noise is reduced by using an external microphone and the built-in
microphone of the mobile telephone when using the in-vehicle hands-free kit for mobile
telephone. is there.
[0067]
FIG. 7 is a flow chart for explaining the operation of the sound adjustment apparatus according
to the sixth embodiment. The same steps as those in FIG.
[0068]
First, at step ST21, the user emits a voice (input voice) to the external microphone of the invehicle hands-free kit.
At this time, ambient noise is picked up by the external microphone together with the voice (step
ST22).
Assuming that the input voice is (A) and the ambient noise is (B), (Α) + (B) is input to the external
microphone (step ST23).
10-04-2019
13
[0069]
In addition, the mobile phone is fixed to the main body of the in-vehicle hands-free kit.
At step ST24, ambient noise (B) is picked up by operating the built-in microphone of this
telephone.
At this time, the user's voice is sufficiently small and almost negligible because there is a
sufficient distance to the input level on the external microphone side.
[0070]
Next, in step ST26, the sound input from the two distant microphones is converted into data by
the mobile phone (or the in-vehicle hands-free kit main body), and each data converted into data
is converted according to the equation (1) Calculate the difference.
[0071]
By differentially calculating the converted data, ambient noise (B) can be eliminated.
[0072]
(A + Β) −Β = A (1) Only the voice data of the user remains in the differentially calculated voice
data.
The transmission signal (A) is transmitted to the other party (step ST17).
[0073]
In step ST18, on the other party side, the reception signal (A) is voice-processed on the other
party side, and in step ST19, only the input voice (A) in which the ambient noise is reduced can
be reproduced from the receiver (speaker) of the other party.
10-04-2019
14
[0074]
As described above, the sound adjustment apparatus according to the sixth embodiment detects
an audio signal by the on-vehicle external microphone and the built-in microphone built in the
portable terminal, and calculates the input difference of these audio signals. Since the audio
signal processing for reducing the ambient noise is performed, the ambient noise can be
extremely easily reduced, and a clear output of only the voice can be expected from the other
party.
[0075]
Further, by having two or more external microphones of the in-vehicle hands-free kit, this
difference system can be used only with the hands-free kit, and ambient noise can be reduced.
[0076]
The sound adjustment apparatus according to the seventh embodiment of the present invention
is good in the cellular phone (or in-vehicle hands-free kit), by cutting the input sound at a certain
level and further amplifying it to reduce ambient noise, thereby achieving good performance. It
provides call quality.
[0077]
FIG. 8 is a diagram for explaining the operation of the acoustic adjustment device according to
the seventh embodiment.
[0078]
First, in step ST31, the built-in microphone of the mobile phone collects the synthetic sound of
the user's transmission voice and the ambient sound of the usage environment.
These synthesized sounds are digitally processed in the mobile phone and sampled as signal
levels.
[0079]
When the call sound and the ambient noise level are compared, the synthesized signal is cut at a
certain level by utilizing a characteristic that the level of the call sound of the user close to the
microphone side is usually increased (step ST32).
10-04-2019
15
[0080]
Next, at step ST33, the synthesized signal is amplified by the level at which it is cut and is raised
to the original level.
This amplified signal is sent to the other party.
[0081]
As described above, the acoustic adjustment device according to the seventh embodiment
reduces the ambient noise by amplifying the cut level after cutting the synthetic signal level of
the synthetic signal of the voice signal and the ambient noise at a predetermined level. Since the
audio signal processing is performed, it is possible to almost cut the ambient noise, and to
transmit the voice with less ambient noise to the other side.
[0082]
Here, by combining with the method of each embodiment described above, the ambient noise
level is measured in advance, and a more reliable ambient noise cut is possible by setting the
level to the cut level.
[0083]
Therefore, if the acoustic adjustment device having such excellent features is applied to a
wireless portable terminal device such as a portable telephone including a PHS or an on-vehicle
mobile terminal by transmitting and receiving a wireless signal, the wireless portable terminal
device can be more easily used. Can make good calls.
[0084]
Although the sound adjustment device according to each of the above embodiments can be
applied to a wireless calling device such as a mobile telephone as described above, it is of course
not limited thereto, and any device that performs the sound adjustment can be applied. It is
needless to say that the present invention is applicable to an apparatus (e.g., a pager).
[0085]
10-04-2019
16
In each of the above-described embodiments, the processing in the control unit has been
described as an example of the processing means, but any processing may be performed as long
as noise is detected around the user and data output is detected. It goes without saying that a
processing method such as this may be used.
[0086]
Furthermore, it goes without saying that the types of devices constituting the sound adjustment
device, the wired / wireless system, etc. are not limited to the embodiment described above.
[0087]
According to the present invention, the sound adjusting apparatus comprises noise signal
detecting means for detecting ambient noise, and volume setting means for setting a ringing
sound level based on the noise signal detected by the noise signal detecting means. Since the
system is provided with the ringing means for ringing at the ringing level set by the volume
