[0035]
<Operation> Next, the operation of the audio system 1 of the present embodiment will be
described. The communication device 40, the speaker device 20, and the SW 30 are powered on,
and the communication device 40 broadcasts a master request to function as a master. The
speaker device 20 and the SW 30 search whether or not the master is within the communication
range, and establish a link with the communication device 40 when the master request of the
communication device 40 is received. The communication module 42 of the communication
device 40 assigns an ID for identifying each of the speaker device 20 and the SW 30, and a
connection request signal including the assigned ID and an ID for identifying the communication
module 42 for each device. Is sent. The speaker device 20 and the SW 30 store the assigned ID in
the own device, and transmit a response signal to the connection request signal to the
communication device 40. As a result, wireless communication can be established between the
communication device 40 and the speaker device 20, and between the communication device 40
and the SW 30, and stream data transmission of audio data from the communication device 40 to
the speaker device 20 and the SW 30 becomes possible. Transition. Here, in the portable audio
device 41, when audio data is selected by a user operation and reproduction is instructed, stream
transmission of audio data is started from the communication device 40 to the speaker device 20
and the SW 30. Hereinafter, operations performed by the speaker device 20 and the SW 30 in
the above-described state will be described using the operation flow of FIG. 7.
[0036]
The speaker device 20 sequentially receives audio data from the communication device 40,
extracts audio data corresponding to a reproduction band according to setting information stored
in the storage unit 213, AD converts it, and generates an audio signal. The amplification unit 216
amplifies the audio signal at an amplification factor according to the volume value set in the
setting information, and sends it to the sound emission unit 217. In this case, since the
reproduction band is determined based on the setting information shown in FIG. 3A, sound
emission of the mid-high frequency audio data is started (step S11).
11-04-2019
11
[0037]
On the other hand, also in the SW 30, similarly to the speaker device 20, audio data is
sequentially received from the communication device 40, and the audio processing unit 313
extracts low-range audio data from the received audio data, and amplification is preset. The audio
signal is amplified according to the rate, and the sound emitting unit 314 emits the sound (step
S21). As a result, the low-range audio data is emitted from the SW 30. The band at this time is a
default band preset in the SW 30. Note that the previously set bandwidth may be used instead of
the default bandwidth.
[0038]
On the other hand, the control unit 214 of the speaker device 20 controls the communication
control unit 212 to output, from the wireless communication unit 211, a detection signal for
detecting the switch 30 capable of wireless connection. The detection signal includes information
indicating the ID of the speaker device 20 (step S12). When the SW 30 receives the detection
signal transmitted from the speaker device 20 in step S12 via the wireless communication unit
311 (step S22: YES), the ID assigned to the SW 30 is output to the detection signal. A response
signal including the information to be shown is transmitted to the speaker device 20 (step S23).
By this processing, the speaker device 20 and the SW 30 can communicate wirelessly.
[0039]
When the control unit 214 of the speaker device 20 receives the response signal from the SW
30, that is, when the SW 30 is detected (step S13: YES), the setting shown in FIG. 3B stored in the
storage unit 213 Information on SW is extracted from the information to generate sound
emission control information (step S14).
[0040]
The control unit 214 determines whether or not the setting information has been changed (step
S15).
For example, if the user performs an operation to change the setting of the volume and the like
through the operation unit 218 (step S15: YES), the process returns to step S14 to update the
11-04-2019
12
setting information and control the sound emission from the updated setting information.
Generate information. If the setting information has not been changed, or if the setting
information has not been changed again (step S15: NO), the process proceeds to step S16. In this
case, in the command shown in FIG. 4, the ID assigned to the SW 30 is set as the destination
Node ID, information indicating a band setting instruction is set in the control ID, and sound
emission control information indicating the band of the SW 30 is set in the data section. The
sound emission control command is generated and transmitted to the SW 30. Also, when there is
a change in the volume value, information indicating notification of volume value change is set in
the control ID, and a sound emission control command in which sound emission control
information indicating the volume value of the SW 30 is set in the data section is also generated.
Then, it transmits to the SW 30 (step S16).
[0041]
The control unit 214 controls the audio processing unit 215 so that the band and volume
correspond to the setting information shown in FIG. Thereby, the audio signal of the band set
according to the presence of the SW is emitted from the speaker device 20. (???????)?
[0042]
On the other hand, when the communication control unit 312 of the SW 30 receives the sound
emission control command from the speaker device 20 via the wireless communication unit 311
(step S24: YES), the received sound emission control command is sent to the audio processing
unit 313. Send out. Then, the audio processing unit 313 extracts audio data of the band
instructed by the sound emission control command from the audio data sequentially received
through the wireless communication unit 311, and the volume value instructed by the sound
emission control command The tone waveform signal of the audio data is amplified at an
amplification factor according to V.sub.1 and output from the sound output unit 314 (step S25).
[0043]
In step S13, when the control unit 214 of the speaker device 20 can not receive the response
signal from the SW 30 and can not detect the SW 30 (step S13: NO), the process of step S11 is
continued. The emission of audio data according to the setting information of the speaker device
20 is continued.
11-04-2019
13
[0044]
Further, in step S22, when the detection signal is not received via the wireless communication
unit 311 of the SW 30 (step S22: NO), or in step S24, the communication control unit 312 of the
SW 30 via the wireless communication unit 311. If the sound output control command is not
received from the speaker device 20 (step S24: NO), the processing of step S21 is continued, and
the SW 30 is set to the default (or previous) volume and band Emits an audio signal of
[0045]
Note that the mute process may be performed so as not to emit sound until ?YES? is
determined in step S22.
[0046]
As described above, in the present embodiment, the reproduction band of the speaker device 20
is automatically switched between the presence and the absence of the SW 30, and the audio
data transmitted from the communication device 40 is further divided into the speaker device 20
and the SW 30. When the speaker device 20 issues a sound, the speaker device 20 instructs the
SW 30 on volume and band control information related to the sound emission, and the volume
and band of the speaker device 20 and the SW 30 are automatically adjusted in a well-balanced
manner.
