The transmitter 100 will be described. The transmitter 100 includes a control unit 101, a signal
processing unit 102, an RF module 103, and an operation switch 104. The control unit 101
includes a microcomputer (μC), and controls the operation of each unit of the transmitter 100.
The signal processing unit 102 generates a 2-channel audio signal for headphone drive from a
multi-channel audio signal such as 5.1 channel or 7.1 channel, for example.
[0020]
The RF module 103 transmits the two-channel audio signal obtained by the signal processing
unit 102 to the headphone device 200. Further, the signal processing unit 103 receives a control
signal sent from the headphone device 103 and sends it to the control unit 101. The control
signal is, for example, a control signal for controlling the signal processing unit 102, and is, for
example, a control signal for adjusting a center level or a subwoofer level, and further, operating
a sound field. Also, this control signal is, for example, a control signal for controlling on / off of
the power supply.
[0021]
The operation switch 104 configures a user interface that allows the user to perform various
operations or settings. The user can set to invalidate the control by the control signal sent from
the headphone device 103 by operating the operation switch 104. The control unit 101
invalidates the control based on the control signal sent from the headphone device 103 based on
the user setting.
[0022]
Further, when the control unit 101 invalidates the control based on the control signal sent from
the headphone device 103, the number of the headphone devices 200 being paired is a
predetermined number or more, and in this embodiment, a plurality of headphone devices 200
are used. The control by the control signal sent from the headphone device 103 is invalidated.
The two-channel audio signal is transmitted from the RF module 103 to the headphone device
200 being paired.
01-05-2019

[0023]
The user can set the headphone device 200 to be paired by operating the operation switch 104.
The control unit 101 can check whether the number of headphone devices 200 being paired is
more than one or not by monitoring the headphone devices 200 that are pairing-set by the
operation of the operation switch 104 in this way. The change in the number can be recognized.
As described above, when the number of headphone devices 200 being paired is plural, the user
operates the operation switch 104 to determine whether control by the control signal sent from
the headphone device 103 is to be invalidated or not. It can be set.
[0024]
When disabling the control based on the control signal sent from the headphone device 103, the
control unit 101 notifies each headphone device 200 being paired via the RF module 103 to that
effect. By this notification, in the headphone device 103, for example, that effect can be displayed
on the display unit, and the convenience of the user can be achieved.
[0025]
The headphone device 200 will be described. The headphone device 200 includes a control unit
201, an RF module 202, and an operation switch 203. The control unit 201 includes a
microcomputer (μC), and controls the operation of each unit of the headphone device 200.
[0026]
The RF module 202 receives the two-channel audio signal sent from the transmitter 100.
Further, the RF module 202 transmits to the transmitter 100 a control signal to be transmitted to
the transmitter 100 generated from the control unit 201. As described above, this control signal
is, for example, a control signal for controlling the signal processing unit 102 of the transmitter
100, a control signal for controlling on / off of the power supply, or the like.

The operation switch 203 configures a user interface that allows the user to perform various
operations or settings. By operating the operation switch 203, the user can generate a control
signal to be transmitted from the control unit 201 to the transmitter 100 described above.
[0028]
Further, the user can set to invalidate the transmission of the control signal by operating the
operation switch 203. The control unit 201 invalidates the transmission of the control signal
based on the user setting. The invalidation of the transmission of the control signal is achieved by
stopping the generation of the control signal from the control unit 201 or by stopping the
transmission of the control signal from the RF module 202.
[0029]
The transmission and reception operation of the two-channel audio signal in the wireless
surround headphone system 10 shown in FIG. 1 will be briefly described. The signal processing
unit 102 of the transmitter 102 generates a two-channel audio signal for headphone driving
from a multi-channel audio signal such as 5.1 channel or 7.1 channel, for example. In this case,
the signal processing unit 102 generates a two-channel audio signal in which sound image
localization of each channel in the multichannel is favorably performed. The two-channel audio
signal is sent from the signal processing unit 102 to the RF module 103, and is sent to one or
more headphone devices 200 paired with the transmitter 100.
[0030]
Also, the RF module 202 of the headphone device 200 receives the two-channel audio signal sent
from the transmitter 100. The two-channel audio signal includes a left channel audio signal and a
right channel audio signal, which are respectively supplied to a speaker unit (not shown) to
perform audio reproduction.
[0031]
01-05-2019

Further, the control unit 201 of the headphone device 200 generates a control signal to be
transmitted to the transmitter 100 based on the operation of the operation switch 203 by the
user. This control signal is sent to the RF module 202 and sent to the transmitter 100. In the
headphone device 200, when the transmission of the control signal is invalidated, the
transmission of such a control signal to the transmitter 100 is not performed.
[0032]
Further, in the RF module 103 of the transmitter 100, the control signal sent from the
headphone device 200 is received and sent to the control unit 101. The control unit 101 controls
the signal processing unit 102 based on the control signal, or controls on / off of the power
supply. Under the control of the signal processing unit 102, for example, adjustment of the
center level and the subwoofer level, and further operation of the sound field are performed. In
the transmitter 100, such control is not performed when control by the control signal from the
headphone device 200 is invalidated.
[0033]
The flowchart of FIG. 2 shows an example of the control operation in the control unit 101 of the
transmitter 100. In step ST1, the control unit 101 starts the control operation in response to
power on. Then, in step ST2, the control unit 101 determines whether the control by the control
signal from the headphone device 200 should be invalidated. The control unit 101 makes a
determination based on the user setting by the operation switch 104 or the number of
headphone devices 200 being paired.
[0034]
When determining that the control should be disabled, in step ST3, the control unit 101 disables
the control based on the control signal from the headphone device 200. For example, the control
signal from the headphone device 200 received by the RF module 103 is not sent to the control
unit 101. On the other hand, when determining not to invalidate, in step ST4, the control unit
101 validates the control based on the control signal from the headphone device 200. For
example, the control signal from the headphone device 200 received by the RF module 103 is
sent to the control unit 101.

[0035]
After the processes of steps ST3 and ST4, the control unit 101 proceeds to the process of step
ST5. In step ST5, the control unit 101 performs boot processing. Then, in step ST6, the control
unit 101 starts reproduction. Thereby, transmission of a two-channel audio signal from the
transmitter 100 to the headphone device 200 is started.
[0036]
The flowchart in FIG. 3 illustrates an example of the control operation of the control unit 101
when there is a change in the number of paired headphone devices 200. This example is an
example in the case where the setting to invalidate the control by the control signal sent from the
headphone device 103 is enabled when the number of the headphone devices 200 being paired
is plural. .
[0037]
In step ST11, the control unit 101 starts the control operation in accordance with the change in
the number of headphone devices 200. Then, in step ST12, the control unit 101 determines
whether the number of headphone devices 200 is more than one.
[0038]
When determining that the number is more than one, the control unit 101 invalidates the control
based on the control signal from the headphone device 200 in step ST13. For example, the
control signal from the headphone device 200 received by the RF module 103 is not sent to the
control unit 101. On the other hand, when determining that the number is not plural, the control
unit 101 enables control by the control signal from the headphone device 200 in step ST14. For
example, the control signal from the headphone device 200 received by the RF module 103 is
sent to the control unit 101.
[0039]
01-05-2019
10
After the processes of steps ST13 and ST14, the control unit 101 proceeds to the process of step
ST15. In step ST15, the control unit 101 cancels the mute. Although not described above, in
accordance with the change in the number of headphone devices 200, the transmitter 100 is put
into the mute state. Then, in step ST16, the control unit 101 starts reproduction. As a result,
transmission of the two-channel audio signal from the transmitter 100 to the headphone device
200 is resumed.
[0040]
The flowchart in FIG. 4 illustrates an example of the control operation of the control unit 201 of
the headphone device 200. In step ST21, the control unit 201 starts the control operation in
response to power on. Then, in step ST22, the control unit 201 determines whether transmission
of the control signal to the transmitter 100 should be invalidated. The control unit 201 makes a
determination based on user setting or the like by the operation switch 203.
[0041]
When determining that it should be invalidated, the control unit 201 invalidates the transmission
of the control signal to the transmitter 100 in step ST23. For example, the control unit 201 does
not send a control signal to the RF module 202. On the other hand, when it is determined that
the transmission is not invalidated, the transmission of the control signal to the transmitter 100
is validated in step ST24. For example, the control unit 201 sends a control signal to the RF
module 202.
[0042]
After the processing of step ST23 and step ST24, the control unit 201 proceeds to the processing
of step ST25. In step ST25, the control unit 201 performs boot processing. Then, in step ST26,
the control unit 201 starts reproduction. Thereby, the two-channel audio signal sent from the
transmitter 100 is received and the reproduction is started.
[0043]
01-05-2019
11
As described above, in the wireless surround headphone system 10 shown in FIG. 1, the control
by the control signal from the headphone device 200 can be canceled by the transmitter 100,
and the control signal to the transmitter 100 by the headphone device 200. Sending can be
disabled. Therefore, for example, when the number of headphone devices 200 to be paired with
the transmitter 100 is plural, it is possible to prevent an influence of a certain user operation
from affecting another user. For example, it is effective when providing the same audio signal at
one time to a large number of people such as a product briefing session.
[0044]
<2. Modified Example> In the above embodiment, when the number of headphone devices
200 paired with the transmitter 100 is plural, in the transmitter 100, the control signals from all
the headphone devices 200 are invalidated. . However, it is also conceivable to enable the setting
of the master / slave in the headphone device 200 and to invalidate only the control signal from
the headphone device 200 set as the slave.
[0045]
In this case, when the number of headphone devices 200 paired with the transmitter 100 is
plural, the control by the control signal from the headphone device 200 set as the master is
validated. In this case, the transmission of the control signal to the transmitter 100 may be
invalidated in the headphone device 200 set as a slave.
[0046]
Further, in the above-described embodiment, when the transmitter 100 determines that the
control by the control signal from the headphone device 200 should be invalidated, a process of
invalidating the control signal is performed by itself. However, in this case, it is also conceivable
that the transmitter 100 transmits the invalidation control signal to the headphone device 200
through the RF module 103, and the headphone device 200 invalidates the transmission of the
control signal to the transmitter 100.
