The pairing maintenance button 13 switches between an ON state and an OFF state each time a user press is received, and outputs state information indicating the current state to the control unit 20A.

  The pairing maintenance button 13 is not limited to the above configuration. For example, it may be a button that is pressed into the housing only when pressed. Further, instead of the button shape, it may be realized by an electrostatic touch switch, a touch panel, or the like. In these examples, since the pairing maintenance button 13 is not distinguished between the ON state and the OFF state, whether or not to pair with the voice transmitter 30A connected to the voice receiver 10A instead of the state information. This information is output to the control unit 20A (specifically, a pairing control unit 21 described later).

  As described above, the user installs the voice receiver 10 </ b> A in any one of the plurality of voice transmitters 30 </ b> A in order to charge the secondary battery 18.

  The pairing control unit 21 determines whether to pair the audio receiver 10A and the audio transmitter 30A when the audio receiver 10A is installed in the audio transmitter 30A. Specifically, the pairing control unit 21 detects that the connection terminal 14 is electrically connected to the connection terminal 34 of the voice transmitter 30A, so that the voice receiver 10A is installed in the voice transmitter 30A. When this is detected, it waits for reception of the Bluetooth address from the voice transmitter 30A. When receiving the Bluetooth address, the pairing control unit 21 specifies whether the latest state information acquired from the pairing maintenance button 13 is information indicating an ON state or an OFF state. When the latest status information is information indicating the OFF state, pairing is performed with the voice transmitter 30A (voice transmitter 30A1 in which the voice receiver 10A is installed) that is the transmission source of the Bluetooth address. Note that the details of the pairing process are the same as those of the existing technology, and thus description thereof is omitted here.

  On the other hand, when the latest state information is information indicating the ON state, the pairing control unit 21 outputs a pairing rejection notification to the communication control unit 22A and causes the voice transmitter 30A to transmit the notification. Thereby, the pairing between the voice receiver 10A and the voice transmitter 30A1 is not executed, and the pairing between the voice receiver 10A and the voice transmitter 30A2 is maintained.

  The communication control unit 22A controls communication with the voice transmitter 30A. Specifically, the communication control unit 22 </ b> A acquires the audio data transmitted from the audio transmitter 30 </ b> A via the communication unit 11 and outputs the audio data to the audio control unit 23.

  The output volume setting unit 24A sets the volume of the sound output from the sound output unit 12. Specifically, when the output volume setting unit 24A acquires the dial volume information from the volume setting dial 15, the output volume setting unit 24A outputs the dial volume information to the audio output unit 12 (amplifier). Thereby, the audio | voice output part 12 can output an audio | voice with the volume which dial volume information shows. In the audio receiver 10A, as shown in FIG. 1, dial volume information is output to the audio output unit 12 via the output volume setting unit 24A, but from the volume setting dial 15 to the audio output unit 12 (amplifier). It may be output directly.

Specifically, the communication unit 31 transmits audio data acquired from the electronic device and information necessary for pairing (for example, identification information for identifying the audio receiver 10A) to the audio receiver 10A. The communication unit 31 receives information necessary for pairing (for example, identification information for identifying the audio receiver 10A) transmitted from the audio receiver 10A, and outputs these data to the control unit 40A. .

  The concave portion 32 is a concave portion provided in the voice transmitter 30A having a substantially rectangular parallelepiped shape, and is used for installing the voice receiver 10A in the voice transmitter 30A. In other words, the recess 32 is large enough to fit the audio receiver 10A.

  The recess 32 is not an essential configuration, and the audio transmitter 30A only needs to be configured so that the audio receiver 10A can be placed thereon. For example, the upper surface of the voice transmitter 30A may be a flat surface. If positioning is necessary when the audio receiver 10A is placed on the audio transmitter 30A, either one of the audio transmitter 30A and the audio receiver 10A is provided with an alignment rib or protrusion, and the other A surface or hole corresponding to the rib or protrusion may be provided.

  The audio input terminal 33 is a terminal for acquiring audio data from the electronic device.

  The connection terminal 34 is electrically connected to the connection terminal 14 of the audio receiver 10A. When the control unit 40A detects that the connection terminal 34 and the connection terminal 14 are electrically connected, the control unit 40A recognizes that the audio receiver 10A and the audio transmitter 30A are connected, and the audio receiver 10A and the audio receiver 10A. Pairing with the transmitter 30A is started. In other words, the electrical connection between the connection terminal 34 and the connection terminal 14 is a trigger for pairing between the audio receiver 10A and the audio transmitter 30A. Note that a pull-up resistor or a pull-down resistor is connected to the connection terminal 34 in order to stabilize the voltage when not electrically connected to the connection terminal 14.

  The power supply terminal 35 is a terminal for receiving power from an external power supply. The power received by the power supply terminal 35 is sent to each part of the audio transmitter 30A, and when the audio receiver 10A is installed in the audio transmitter 30A, the audio receiver 10A via the charging terminal 37a and the charging terminal 37b. Sent to.

  The charging control circuit 36 is a circuit for sending a part of the power received by the power supply terminal 35 to the charging terminal 16a and the charging terminal 16b of the audio receiver 10A via the charging terminal 37a and the charging terminal 37b.

  The charging terminal 37a and the charging terminal 37b are terminals for supplying the power acquired from the charging control circuit 36 to the audio receiver 10A by being electrically connected to the charging terminal 16a and the charging terminal 16b of the audio receiver 10A. It is.

Further, the communication control unit 43A outputs various information such as a pairing rejection notification acquired from the communication unit 31 to the pairing control unit 41A.

(Flow of pairing process executed by the wireless speaker system 1A)
Next, the flow of the pairing process (control method of the audio receiver 10A) executed by the wireless speaker system 1A will be described with reference to FIG. FIG. 3 is a flowchart illustrating an example of a pairing process performed by the wireless speaker system 1A.

  The pairing maintenance button 13 of the audio receiver 10A is turned ON or OFF by the user's depression before the audio receiver 10A is installed in the audio transmitter 30A (S11, pairing selection reception step).

  The pairing control unit 41A of the audio transmitter 30A detects that the audio receiver 10A is installed by detecting that the connection terminal 14 and the connection terminal 34 are electrically connected (YES in S1). ). At this time, the charging terminal 16a and the charging terminal 16b of the audio receiver 10A are electrically connected to the charging terminal 37a and the charging terminal 37b of the audio transmitter 30A. Thereby, the charging control circuit 36 of the voice transmitter 30A supplies the charging power to the voice receiver 10A via the charging terminal 37a and the charging terminal 37b (S2). Then, the charging control circuit 17 of the audio receiver 10A charges the secondary battery 18 using the charging power (S12, power acquisition step).

  Next, the pairing control unit 41A of the voice transmitter 30A starts the pairing process (S3). Specifically, the pairing control unit 41A outputs the Bluetooth address to the communication control unit 22A, and the communication control unit 43A transmits the Bluetooth address to the voice receiver 10A via the communication unit 31.

  Next, the communication unit 11 that has received the Bluetooth address outputs the Bluetooth address to the communication control unit 22A. The communication control unit 22A outputs the acquired Bluetooth address to the pairing control unit 21. When acquiring the Bluetooth address, the pairing control unit 21 specifies whether the latest state information acquired from the pairing maintenance button 13 is information indicating an ON state or an OFF state. (S13).

  When the latest status information indicates that the pairing maintenance button 13 is in the OFF state (NO in S13), the pairing control unit 21 executes a pairing process (S15, pairing determination step). Specifically, pairing with the audio transmitter 30A indicated by the acquired Bluetooth address is newly performed. If the acquired Bluetooth address is the same as the Bluetooth address of the voice transmitter 30A currently paired, the pairing control unit 21 maintains the pairing with the voice transmitter 30A indicated by the Bluetooth address. To do. Note that “when the acquired Bluetooth address is the same as the Bluetooth address of the voice transmitter 30A currently paired” means that the user installs the voice receiver 10A in the paired voice transmitter 30A. This is the case.

  On the other hand, when the latest status information indicates that the pairing maintenance button 13 is in the ON state (YES in S13), the pairing control unit 21 outputs a pairing rejection notification to the communication control unit 22A. The communication control unit 22A transmits the pairing rejection notification to the voice transmitter 30A via the communication unit 11 (S14, pairing determination step).

  Next, when a pairing rejection notification is received via the communication unit 31 and the communication control unit 43A (YES in S4), the pairing control unit 41A of the voice transmitter 30A stops the pairing process (S5).

  On the other hand, when the pairing rejection notification is not received (YES in S4), the pairing control unit 41A of the voice transmitter 30A continues the pairing process. When the pairing between the audio receiver 10A and the audio transmitter 30A is completed, the communication control unit 43A receives the audio data acquired from the electronic device via the audio input terminal 33 and the Bluetooth address received during the pairing process. Is transmitted to the voice receiver 10A indicated by (2) via the communication unit 31 (S6).

  Finally, the communication control unit 22A of the audio receiver 10A outputs the audio data acquired through the communication unit 11 to the audio control unit 23. The voice control unit 23 causes the voice output unit 12 to output voice based on the acquired voice data (S16). Specifically, in step S13, when the latest status information indicates that the pairing maintenance button is in the ON state, the voice transmission is different from the voice transmitter 30A in which the voice receiver 10A is installed. Voice data is received from the machine 30A, and the voice control unit 23 outputs voice based on the voice data. On the other hand, in step S13, when the latest status information indicates that the pairing maintenance button is OFF, the audio data is received from the audio transmitter 30A in which the audio receiver 10A is installed, The control unit 23 outputs a sound based on the sound data.

  As described above, the voice receiver 10A according to the present embodiment operates with the power of the secondary battery 18 that outputs the voice received by wireless communication from the paired voice transmitter 30A among the plurality of voice transmitters 30A. Voice receiver. When the audio receiver 10A is installed (electrically connected) to the audio transmitter 30A, the charging terminals 16a and 16b and the charging control circuit that charge the secondary battery 18 with the power supplied from the audio transmitter 30A. 17 and the pairing maintenance button 13 for accepting the user's selection as to whether or not to perform pairing with the installed (electrically connected) voice transmitter 30A, and installed (electrically connected) to the voice transmitter 30A. The pairing maintenance button 13 determines whether to pair with the voice transmitter 30A or to maintain the pairing with the currently paired voice transmitter 30A according to the user's selection received. And a pairing control unit 21 for

  According to this configuration, the pairing control unit 21 accepts a selection indicating that the pairing maintenance button 13 performs pairing with the voice transmitter 30A (voice transmitter 30A1) in which the voice receiver 10A is installed. If it is in the OFF state, pairing between the audio receiver 10A and the audio transmitter 30A1 is performed. On the other hand, the pairing control unit 21 receives the selection indicating that the pairing maintenance button 13 does not perform pairing with the voice transmitter 30A1 (is in the ON state), the voice receiver 10A. Then, the secondary battery 18 is only charged without pairing with the audio transmitter 30A1. In other words, when the user wants to charge only the voice receiver 10A, the pairing maintenance button 13 is turned on before the user installs the voice receiver 10A in the voice transmitter 30A1, thereby the voice receiver It is possible to prevent pairing between 10A and the voice transmitter 30A1 automatically.

  In the present embodiment, the wireless speaker system 1A in which the receiver and the transmitter transmit and receive audio data by wireless communication has been described as the wireless communication system. However, the present invention is not limited to this. In other words, any wireless communication system in which the receiver and the transmitter transmit and receive information by wireless communication may be used. For example, the transmitter transmits information such as videos and photos received from electronic devices such as personal computers to the receiver. It may be a wireless communication system that displays a moving image or a photograph received by the receiver on its own display unit.

  In the above-described example, when the pairing maintenance button 13 is in the ON state, the pairing control unit 21 of the voice receiver 10A transmits a pairing rejection notification to the voice transmitter 30A, and the pairing rejection notification is transmitted. The received voice transmitter 30A is configured to stop the pairing process. However, the voice transmitter 30A is configured to stop the pairing process when it recognizes that the pairing maintenance button 13 is ON, in other words, the pairing with the own device is not performed. Often, the trigger for the voice transmitter 30A to stop the pairing process is not limited to the reception of the pairing rejection notification. For example, when the information necessary for pairing is not received from the audio receiver 10A within a predetermined time, the pairing control unit 41A may stop the pairing process.

  In the above-described example, when the connection terminal 14 and the connection terminal 34 are electrically connected, pairing between the audio receiver 10A and the audio transmitter 30A is started. However, the trigger for starting pairing is not limited to the connection terminal 14 and the connection terminal 34 being electrically connected. For example, pairing may be started when the charging terminal 16a and the charging terminal 16b are electrically connected to the charging terminal 37a and the charging terminal 37b. In the case of this configuration, the connection terminal 14 and the connection terminal 34 may be omitted.

  Further, in the above-described example, the example in which the pairing maintenance button 13 is provided in the voice receiver 10A has been described, but is the pairing between the voice receiver 10A electrically connected and the voice transmitter 30A executed? The button for accepting the selection of whether or not may be provided in the voice transmitter 30A. In the case of this example, when the button is in the ON state, the pairing control unit 41A of the audio transmitter 30A does not transmit the Bluetooth address to the installed audio receiver 10A. Thereby, the audio receiver 10A can maintain pairing with the audio transmitter 30A that is paired (the audio transmitter 30A that is different from the audio transmitter 30A in which the audio receiver 10A is installed). On the other hand, when the button is in the OFF state, the pairing control unit 41A transmits the Bluetooth address to the installed voice receiver 10A. Thereby, the pairing process of the audio | voice transmitter 30A and audio | voice receiver 10A which were electrically connected is performed.

(User-set volume setting process)
In the wireless speaker system 1B, a process of storing the user-set volume data in the audio transmitter 30B will be described with reference to FIG. FIG. 6 is a flowchart showing an example of the flow of output volume setting processing executed by the wireless speaker system 1B.

  First, when the user operates the volume setting dial 15, the volume of the voice output from the voice receiver 10B is adjusted to a volume suitable for the place where the voice transmitter 30B is installed (S21).

  Next, when the volume setting button 51 accepts the user's pressing (S22), the set volume transmitting unit 52 acquires dial volume information indicating the volume of the sound currently output from the audio output unit 12. Then, the set volume transmitting unit 52 outputs the dial volume information to the communication control unit 22B as user set volume data. The communication control unit 22B outputs the user set volume data to the voice transmitter 30B via the communication unit 11 (S23).

The communication control unit 43B outputs the acquired user setting volume data to the setting volume control unit 61. The set volume control unit 61 stores the acquired user set volume data in the set volume storage unit 62. As a result, the user-set volume data indicating the volume suitable for the place where the voice transmitter 30B is installed is stored in the set volume storage unit 62 (S31).

(Flow of pairing process executed by the wireless speaker system 1B)
Next, the flow of the pairing process executed by the wireless speaker system 1B will be described with reference to FIG. FIG. 7 is a flowchart showing an example of a pairing process performed by the wireless speaker system 1B. Steps S41 to S45 and S51 to S54 are the same as steps S1 to S5 and S11 to S14 in the first embodiment, respectively, and thus the description thereof is omitted.

  When the pairing process between the voice receiver 10B and the voice transmitter 30B is executed and the pairing process is completed, the pairing control unit 41B of the voice transmitter 30B notifies the setting volume control unit 61 to that effect. Upon receiving the notification, the set volume control unit 61 reads the user set volume data stored in the set volume storage unit 62 and outputs it to the communication control unit 43B. The communication control unit 43B transmits the acquired user setting volume data to the voice receiver 10B via the communication unit 31 (S46).

  Next, the communication control unit 22B of the audio receiver 10B receives the user setting volume data transmitted from the audio transmitter 30B via the communication unit 11 (S56), and outputs the user setting volume data to the output volume setting unit. To 24B. The output volume setting unit 24B sets the volume of the audio output from the audio output unit 12 based on the received user setting volume data (S57).

  Next, the communication control unit 43B transmits the audio data acquired from the electronic device via the audio input terminal 33 to the paired audio receiver 10B via the communication unit 31 (S47).

  Finally, the communication control unit 22B of the audio receiver 10B outputs the audio data acquired through the communication unit 11 to the audio control unit 23. The voice control unit 23 causes the voice output unit 12 to output voice based on the acquired voice data (S58). The sound volume at this time is not the volume indicated by the volume setting dial 15 but the volume indicated by the user set volume data. Note that the volume setting of the audio output from the audio receiver 10B is the volume setting accepted by the volume setting dial 15 when the pairing with the audio transmitter 30B is released. Specifically, when the pairing control unit 21 of the voice receiver 10B cancels the pairing with the voice transmitter 30B, the pairing control unit 21 notifies the output volume setting unit 24A to that effect. Upon receiving the notification, the output volume setting unit 24A deletes the user set volume data.

  As shown in FIG. 6, the user-set volume data according to the present embodiment operates the volume setting dial 15 while confirming the voice that is actually output from the voice receiver 10B. Now, the configuration is such that when the user presses the volume setting button 51, it is stored in the voice transmitter 30B. However, the user set sound volume data is not limited to that stored in this example. For example, when the voice transmitter 30B is shipped, a plurality of setting tables (not shown) corresponding to the type of room assumed (for example, living room, bedroom, study room, etc.) are stored in the set volume storage unit 62. The configuration may be such that the user selects the setting table in accordance with the room where the audio transmitter 30B is installed. In the case of this example, when the user set volume data is determined by the method shown in FIG. 6, the user set volume data stored at the time of shipment may be overwritten.

  As described above, the audio receiver 10B in the present embodiment is paired with the audio output unit 12 that outputs audio, the output volume setting unit 24B that outputs audio to the audio output unit 12, and the audio transmitter 30B. And a communication control unit 22B that acquires volume information stored in advance in the audio transmitter 30B. Then, the output volume setting unit 24B causes the audio output unit 12 to output audio at the volume indicated by the volume information acquired by the communication control unit 22B when paired with the audio transmitter 30B.

  According to the above configuration, when paired with the sound transmitter 30B, the sound is output from the sound output unit 12 based on the sound volume indicated by the sound volume information stored in the sound transmitter 30B. Therefore, when the sound volume indicated by the sound volume setting dial 15 of the sound receiver 10B is not suitable for the place where the sound transmitter 30B is installed, the sound is prevented from being output at the sound volume. Can be done.

  Further, the audio receiver 10B includes a volume setting button 51 for receiving a user operation for storing the volume of the audio output by the audio output unit 12 in the audio transmitter 30B as user setting volume data, and a volume setting button 51. When a user operation is accepted, the apparatus further includes a set volume transmission unit 52 that generates user set volume data indicating the volume of the sound output by the audio output unit 12 and stores the user set volume data in the audio transmitter 30B.

  According to said structure, the audio | voice volume which the audio | voice output part 12 is outputting can be memorize | stored in the audio | voice transmitter 30B as user setting volume data. Therefore, when paired with the audio transmitter 30B, the volume of the audio output from the audio receiver 10B can be set to the user's desired volume.

  Further, when the sound is output from the sound output unit 12 at a volume set based on the user-set volume data, the user operates the volume setting dial 15 to output the sound volume output from the sound output unit 12. Is assumed to change. At this time, there is a possibility that the volume set based on the user-set volume data and the volume indicated by the volume setting dial 15 before operation are greatly different. In such a case, when the user operates the volume setting dial 15, there is a problem that the volume output from the audio output unit 12 changes abruptly. In order to solve this problem, the output volume setting unit 24B according to the present embodiment specifies the change amount of the volume based on the operation of the volume setting dial 15, and the volume indicated by the user-set volume data with the specified change amount. The configuration may be such that the volume is changed and the changed volume is output to the audio output unit 12. Thereby, since the volume is changed based on the volume indicated by the user-set volume data, it is possible to prevent the volume output from the audio output unit 12 from changing suddenly. Note that the information indicating the volume after the change may be invalidated when the pairing between the audio receiver 10B and the audio transmitter 30B is released.

  According to the above configuration, when the pairing selection accepting unit accepts a selection indicating that the receiver is paired with the transmitter to which the receiver is connected, the pairing determination accepting unit Pair with the transmitter. On the other hand, when the pairing selection accepting unit accepts a selection indicating that pairing with the transmitter is not performed, the pairing selection accepting unit does not perform pairing between the receiver and the transmitter, Only get power. In other words, if the user only wants to obtain power from the transmitter, the user must select not to pair with the transmitter at the pairing selection accepting unit before connecting the receiver to the transmitter. Thus, the receiver and the transmitter can be prevented from pairing automatically. Therefore, it is possible to provide a receiver that can select whether or not to pair with a transmitter when the receiver and the transmitter are connected to supply power to the receiver.

  The receiver according to aspect 3 of the present invention is the user operation for storing the volume of the sound output from the sound output unit 12 in the transmitter as the volume information (user-set volume data) in the aspect 2. When the volume storage operation unit (volume setting button 51) and the volume storage operation unit receive the user operation, the volume information indicating the volume of the sound output by the audio output unit 12 is generated. The volume information control part (setting sound volume transmission part 52) memorize | stored in the said transmitter may be further provided.
