[1-2 the transmission destination determination method of the transmission control unit 281α
And [1-3 Operation procedure of the telephone device] which is the operation procedure of the
telephone device 1 according to the present embodiment will be described with reference to the
drawings.
[0020]
[1-1 Operation Procedure of Ear Identification Means] FIG. 4 is a flowchart showing an operation
procedure of the ear identification unit.
The specific control unit 281α receives the inclination of the receiver 200α output from the
inclination sensor 250 as a detection result (S181). The specific control unit 281α determines
whether it is possible to specify which of the left and right ears to receive from the detection
result (S182). In the present embodiment, it is determined that identification is possible if the
inclination exceeds ± 5 °. Here, this determination will be described with reference to FIG. FIG.
5 is a diagram showing the relationship between either the left or right ear to receive the call and
the inclination of the receiver 200α. The tilt sensor 250 is a sensor capable of detecting threedimensional information (x, y, z) of the handset. For example, when the x, y, and z axes are
orthogonal to each other, the y-axis direction is defined as the sound output direction of the
speaker 220, and the z-axis direction is defined as the vertical direction, the specific control unit
281α determines the inclination of the receiver 200α in the x-axis direction. It is possible to
identify the ear to receive the call.
[0021]
For example, the diagram of (a-1) is a diagram of the receiver 200α viewed from the y-axis
direction. And the figure which looked at this figure from z axial direction is (a-2). In the state
shown in this figure, the inclination of the receiver 200α in the x-axis direction indicates that the
ear to be received is the left ear. Also, the diagram (b-1) is a diagram of the receiver 200α
viewed from the y-axis direction. And the figure which looked at this figure from z axial direction
is (b-2). In the state shown in this figure, the inclination of the receiver 200α in the x-axis
direction indicates that the ear to be received is the right ear. Therefore, if the specific control
unit 281α obtains the detection result that is the inclination of the x axis of the handset 200α,
it determines that either the left or right ear to be received can be identified. And specific control
part 281 alpha makes an ear specified here temporary specification.
09-05-2019

[0022]
If it is determined that the left or right ear to receive can be specified (S182: YES), the specific
control unit 281α detects the detection result (S183) after a predetermined time (for example,
one second) elapses from the reception of the previous detection result (S181). It is judged
whether or not the ear identified from) and the ear identified temporarily are the same (S184). As
a result, when it is determined that the identification control unit 281α is identical (S184: YES),
the temporarily identified ear is identified as either the left or right ear that the hearing aid user
receives (S185). According to the above operation procedure, the specific control unit 281α can
specify either the left or right ear to which the user listens.
[0023]
[1-2 Transmission Destination Determination Method] The transmission control unit 282α sets
the hearing aid corresponding to the ear identified by the specific control unit 281α as the
transmission destination of the audio signal based on the usage state storage unit 270α. The use
state storage unit 270α stores a state in which the hearing aids corresponding to the two ears
are associated with each other. Hereinafter, the transmission destination determination method
will be described based on the example shown in FIG. In the case of (a), when the left ear is
specified by the specific control unit 281α, the transmission control unit 282α generates a link
700l with the hearing aid 300L (key code: 300L) based on the identifier associated with the left
ear. And transmit an audio signal to the hearing aid 300L. On the other hand, when the specific
control unit 281α specifies the right ear, the transmission control unit 282α establishes a link
700r with the hearing aid 300R (key code: 300R) based on the identifier associated with the
right ear, An audio signal is transmitted to the hearing aid 300R. In the case of (b), when the
identification control unit 281α identifies the left ear, the transmission control unit 282α
transmits an audio signal to the speaker 220 because the identifier of the hearing aid is not
associated with the left ear. On the other hand, if the right ear is specified by the specific control
unit 281α, the transmission control unit 282α establishes a link 700r with the hearing aid
300R based on the identifier associated with the right ear, and sends an audio signal to the
hearing aid 300R. Send.
[0024]
In the case of (c), when the left ear is specified by the specific control unit 281α, the
09-05-2019
8
transmission control unit 282α establishes a link 700l with the hearing aid 300L based on the
identifier associated with the left ear, and the hearing aid 300L. Send an audio signal to On the
other hand, when the identification control unit 281α identifies the right ear, the transmission
control unit 282α transmits an audio signal to the speaker 220 because the identifier of the
hearing aid is not associated with the right ear. As described above, the transmission control unit
282α determines the hearing aid corresponding to the ear specified by the specific control unit
281α as the transmission destination based on the usage state storage unit 270α.
[0025]
[1-3 Operation Procedure of Telephone Device] FIG. 3 is a sequence diagram showing a call
reception operation procedure of the telephone device according to the first embodiment of the
present invention. Here, an incoming call operation procedure of the telephone device 1 in the
use state storage unit 270α shown in FIG. 2A is shown. When incoming call notification is input
from telephone network 400 via telephone line 500 in telephone set main body 100α (S100),
control unit 160α causes display unit 130 to display an incoming call display notifying the user
of an incoming call (S110). The incoming call is ringed using a speaker (not shown in FIG. 1)
included in the telephone set main body 100α.
[0026]
When off-hook is performed using the receiver 200α (S120), the control unit 160α detects this
off-hook by the telephone operation input unit 120, terminates the incoming call display (S130),
and stops the ringing. Then, the control unit 160α causes the display unit 130 to display a call
display notifying the user of the state of the call (S140). Further, the control unit 160α notifies
the telephone network 400 of a response via the telephone line 500 (S150). When this response
notification is notified to the telephone network 400, a communication path is established
between the telephone network 400 and the telephone set main body 100α, and the telephone
device 1 enters a call state. Further, the control unit 160α transmits the off-hook signal
notifying the off-hook and the voice signal in the call to the receiver 200α via the curl code 600

the transmission control unit 282α determines the transmission destination determination
method described above In accordance with, the transmission destination is set to the key code
300R. Then, the transmission control unit 282α transmits, via the wireless channel 700, a
partner search signal for confirming whether the signal has correctly arrived and the response is
made (S190). The hearing aids 300L and 300R that have received the other party's search signal
transmit the key code that is their own identifier to the receiver 200α via the wireless channel
700 (S200, S210), and that it is possible to receive an audio signal as a transmission control unit
Notify 282α.
[0028]
If there is the same key code as the key code (300R) corresponding to the identified right ear
among the received key codes, the transmission control unit 282α of the handset 200α
establishes the link 700r with the hearing aid 300R that has transmitted the key code. (S220).
Then, the transmission control unit 282α controls the wireless circuit I / F 240 to convert the
audio signal in the call into transmittable audio data, and transmits the audio data to the hearing
aid 300R via the link 700r (S230). . The hearing aid 300R that receives this audio data outputs
the audio data as audio.
[0029]
Thereafter, when the user's ear is replaced by the left ear, the specification control portion 281α
specifies the ear to be received as the left ear in accordance with the operation procedure of the
above-described ear identification unit (S240). The transmission control unit 282α transmits a
disconnection signal for disconnecting the already established link 700r to the hearing aid 300R,
and disconnects the link 700r (S250). The hearing aid 300R that has received this disconnection
signal stops audio output.
[0030]
Then, the transmission control unit 282α establishes the link 7001 with the hearing aid 300L
that is the key code 300L that is the transmission destination (S260 to S290) as in the abovedescribed S190 to S230 (S260 to S290), and can transmit the voice signal in the call via the
wireless channel Sound data, and this sound data is transmitted to the hearing aid 300L (S300).
09-05-2019
10
The hearing aid 300L that has received this audio data outputs the audio data as audio.
[0031]
Furthermore, when the user's ear is subsequently replaced by the right ear, the specification
control unit 281α specifies the ear to be received as the right ear according to the operation
procedure of the ear specification unit described above, and the transmission control unit 282α.
Similarly to S250, disconnects the already established link 7001, and transmits an audio signal to
the hearing aid 300R according to the same operation procedure as S190 to S230. The hearing
aid 300R that receives this audio data outputs the audio data as audio.
[0032]
In the telephone set main body 100α, when on-hook is performed using the receiver 200α
(S310), the control unit 160α detects this on-hook by the telephone operation input unit 120,
and ends the call display (S320). Then, the control unit 160α transmits an on-hook signal for
notifying on-hook to the receiver 200α via the curl code 600 (S330), and notifies the
termination to the telephone network 400 via the telephone line 500 (S350). When the
termination notice is notified to the telephone network 400, the communication path is
disconnected between the telephone network 400 and the telephone set main body 100α, and
the telephone device 1 becomes idle (standby).
[0033]
On the other hand, the transmission control unit 282α of the receiver 200α that has received
the on-hook signal transmits a disconnection signal to the link-established hearing aid, for
example, the hearing aid 300L (S340), and disconnects the link 700l. As described above,
according to the telephone device 1 or the receiver 200α according to the present invention,
either the left or right ear to which the hearing aid user listens is specified, and the voice signal is
transmitted only to the hearing aid used by that ear. The hearing aid user can make a call without
feeling discomfort.

is ringed using a speaker (not shown in FIG. 1) included in the telephone set main body 100β.
[0041]
When off-hook is performed using the receiver 200β (S420), the control unit 190β detects the
off-hook by the telephone operation input unit 120 and terminates the incoming call display
(S430) and stops the ringing. Then, the control unit 190β causes the display unit 130 to display
a call display notifying the user of the state of the call (S440). Further, the control unit 190β
notifies the telephone network 400 of the response via the telephone line 500 (S450). When this
response notification is notified to the telephone network 400, a communication path is
established between the telephone network 400 and the telephone set main body 100β, and the
telephone device 2 is in a state of telephone call.
[0042]
Here, if the user receives a call with the right ear, and the specification control unit 191β
specifies the right ear according to the operation procedure of the ear specification unit
described above (S460), the transmission control unit 192β determines the transmission
destination determination method described above In accordance with, the transmission
destination is set to the key code 300R. Then, the transmission control unit 192β transmits, via
the wireless channel 700, a partner search signal for confirming whether the signal has arrived
correctly and a response is made (S470). The hearing aids 300L and 300R that have received the
other party search signal transmit the key code that is their own identifier to the receiver 200β
via the wireless channel 700 (S480, S490), and the transmission control unit indicates that it is
possible to receive an audio signal. Notify 192 beta.

If there is the same key code as the key code (300R) corresponding to the identified right ear
among the received key codes, the transmission control unit 192β of the receiver 200β
establishes the link 700r with the hearing aid 300R that has transmitted the key code. To do
(S500). Then, the transmission control unit 191α converts the audio signal in the call into
transmittable audio data by controlling the wireless channel I / F 160β, and transmits the audio
data to the hearing aid 300R via the link 700r (S510). . The hearing aid 300R that receives this
audio data outputs the audio data as audio.
[0044]
Thereafter, when the user's ear is replaced by the left ear, the specification control unit 191β
specifies the ear to be received as the left ear according to the operation procedure of the ear
identification unit described above (S520). The transmission control unit 192 transmits a
disconnection signal for disconnecting the already established link 700 r to the hearing aid 300
R, and disconnects the link 700 r (S 530). The hearing aid 300R that has received this
disconnection signal stops audio output.
[0045]
Then, the transmission control unit 192β establishes the link 7001 with the hearing aid 300L
that is the key code 300L that is the transmission destination (S540 to S570) as in the abovedescribed S470 to S510 (S540 to S570), and can transmit the voice signal in the call via the
wireless channel Audio data, and this audio data is transmitted to the hearing aid 300L (S580).
The hearing aid 300L that has received this audio data outputs the audio data as audio.
[0046]
Furthermore, when the user's ear is subsequently replaced by the right ear, the specification
control unit 191β specifies the ear to be received as the right ear according to the operation
procedure of the ear identification unit described above, and the transmission control unit 192β.
Similarly to S530, disconnects the already established link 7001, and transmits an audio signal to
the hearing aid 300R according to the same operation procedure as S470 to S510. The hearing
aid 300R that receives this audio data outputs the audio data as audio.

In the telephone set main body 100β, when on-hook is performed using the receiver 200β
(S590), the control unit 190β detects this on-hook by the telephone operation input unit 120,
and ends the call display (S600). Then, the transmission control unit 192β transmits a
disconnection signal to the link-established hearing aid, for example, the hearing aid 300L
(S610), and sends a termination notification to the telephone network 400 via the telephone line
500 (S620). When the termination notice is notified to the telephone network 400, the
communication path is disconnected between the telephone network 400 and the telephone set
main body 100β, and the telephone device 2 becomes idle (standby).
[0048]
As described above, according to the telephone device 2 of the present invention, either the left
or right ear to which the hearing aid user listens is specified, and the audio signal is transmitted
only to the hearing aid used by that ear. A person can make a call without feeling discomfort. In
the embodiment described above, although the incoming call operation has been described as an
example, the ear identifying unit and the transmission control unit operate in the same manner in
the outgoing operation. Further, in the above-described embodiment, although the telephone
main body and the handset are connected by the curled cord 600, they may be connected by
cordless.
[0049]
In the embodiment described above, the inclination sensor 250 is used, but any one capable of
specifying either the left or right ear to receive can be identified. For example, the wireless
electric field strength of the hearing aid is detected and the detection result has a predetermined
value If it exceeds, the ear to receive may be identified as either the left or the right ear. In the
above-described embodiment, the transmission destination of the audio signal is determined
according to the state of the use state storage unit in which the identifier of the hearing aid is
stored in association with each of the left and right ears of the user. The destination of the audio
signal may be determined by the dip switch without using it. Further, the pairing between the left
and right ears and the hearing aid stored in the use state storage unit may be changed. In the
above-described embodiment, the usage state storage unit can be changed by the usage state
