DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] 1 is a block diagram showing the configuration of a wireless microphone system 1 according to an embodiment of the present invention. The wireless microphone system 1 includes a master unit 10, multiple wireless microphones 11-14, and a wireless microphone holder 15. The wireless microphone holder 15 holds the multiple wireless microphones 11-14. The wireless microphone holder 15 also functions as a charging stand for charging the multiple wireless microphones 11-14.

[0011] The master unit 10 and the multiple wireless microphones 11-14 are connected by a predetermined wireless communication standard such as DECT (Digital Enhanced Cordless Telecommunications). The master unit 10 and the wireless microphone holder 15 are connected by wired communication via a LAN cable or the like. However, the master unit 10 and the wireless microphone holder 15 may be connected wirelessly.

[0012] The wireless microphone holder 15 is connected to the wireless microphones 11-14 using a communication standard that combines communication and power supply, such as USB. However, the wireless microphone holder 15 may also be connected to the wireless microphones 11-14 using a dedicated communication terminal and charging terminal. The wireless microphone 11 and the wireless microphone holder 15 may also be connected using a wireless communication standard. The wireless microphone 11 may also receive power from the wireless microphone holder 15 using a non-contact charging standard.

[0013] Fig. 2 is a block diagram showing the configuration of parent unit 10. Fig. 3 is a block diagram showing the configuration of wireless microphone 11. Fig. 4 is a block diagram showing the configuration of wireless microphone holder 15. Note that since wireless microphones 11 to 14 all have the same configuration and function, Fig. 3 shows the configuration of wireless microphone 11 as a representative.

[0014] The parent device 10 includes a CPU 101 , a flash memory 102 , a RAM 103 , a wireless communication unit 104 , and a LAN interface (I / F) 105 .

[0015] CPU 101 reads out a program stored in flash memory 102, which is a storage medium, into RAM 103 to realize a predetermined function. For example, CPU 101 receives audio signals from wireless microphones 11-14 via wireless communication unit 104. Wireless communication unit 104 connects to wireless microphones 11-14 using a wireless communication standard such as DECT, and receives audio signals. Note that the connection standard between master unit 10 and wireless microphones 11-14 is not limited to DECT. For example, master unit 10 and wireless microphones 11-14 may be connected using other wireless communication standards such as Wi-Fi (registered trademark) or Bluetooth (registered trademark).

[0016] CPU 101 transmits the audio signals received from wireless microphones 11-14 to other devices via LAN I / F 105. LAN I / F 105 connects the audio signals received from wireless microphones 11-14 to other devices using a communication standard such as Dante (registered trademark), and transmits the audio signals. Note that the communication standard between master unit 10 and other devices is not limited to Dante (registered trademark). For example, master unit 10 may connect to other devices using other communication standards such as USB and transmit audio signals. Of course, master unit 10 may connect to other devices using wireless communication standards and transmit audio signals.

[0017] The other device is, for example, an information processing device such as a personal computer. The information processing device outputs the sound signal received from the parent device 10 to a speaker. As a result, the information processing device amplifies the voice of the speaker picked up by the wireless microphones 11 to 14 to a venue such as a conference room. Alternatively, the information processing device transmits the sound signal received from the parent device 10 to a remote location via the Internet. As a result, the information processing device may function as a remote conversation device.

[0018] The wireless microphone 11 includes a CPU 111, a flash memory 112, a RAM 113, a wireless communication unit 114, a USB I / F 115, and a microphone unit .

[0019] CPU 111 reads out a program stored in flash memory 112, which is a storage medium, into RAM 113 to realize a predetermined function. For example, CPU 111 receives an audio signal related to a voice picked up by microphone unit 116. CPU 111 transmits the received audio signal to parent unit 10 via wireless communication unit 114. Wireless communication unit 104 connects to parent unit 10 according to a wireless communication standard such as DECT as described above, and transmits the audio signal.

[0020] The USB I / F 115 is connected to the wireless microphone holder 15. The USB I / F 115 communicates with the wireless microphone holder 15 and receives power from the wireless microphone holder 15.

[0021] The function of communicating with the wireless microphone holder 15 and the function of receiving power from the wireless microphone holder 15 may be configured separately.

[0022] The wireless microphone holder 15 includes a pairing button 151 , a CPU 152 , a RAM 153 , a LAN I / F 154 , a USB I / F 155 , and a flash memory 156 .

[0023] Pairing button 151 is provided on the housing of wireless microphone holder 15. When pairing button 151 is pressed, wireless microphone holder 15 accepts an instruction to pair wireless microphones 11 to 14 with master unit 10.

[0024] The CPU 152 reads out a program stored in a flash memory 156, which is a storage medium, into the RAM 153, and realizes predetermined functions of the connection unit and the like of the present invention. For example, the CPU 152 communicates with the parent unit 10 via a LAN I / F 154. The CPU 152 also communicates with the wireless microphones 11-14 via a USB I / F 155. The USB I / F 155 also functions as a power supply unit that supplies power to the wireless microphones 11-14.

[0025] Furthermore, flash memory 156 stores identification information of parent unit 10. The identification information of parent unit 10 is information necessary for connecting to parent unit 10 using a communication standard such as DECT. When CPU 152 receives a pairing instruction from pairing button 151, it reads out the identification information stored in flash memory 156 and transmits it to the wireless microphone connected to USB1 / F 155. The wireless microphone connects to parent unit 10 using the received identification information.

[0026] FIG. 5 is a flowchart showing the operations of the wireless microphones 11 to 14, the wireless microphone holder 15, and the master unit 10. As shown in FIG.

[0027] The wireless microphone holder 15 receives a pairing instruction via the pairing button 151 (S11). It is not necessary to receive the pairing instruction via the pairing button 151. For example, the wireless microphone holder 15 may receive a pairing instruction when it detects that a wireless microphone is mounted. In this case, the wireless microphone holder 15 receives a pairing instruction every time it detects that a wireless microphone is mounted. Alternatively, the wireless microphone holder 15 may receive a pairing instruction via a GUI (for example, a WEB UI for receiving settings of the master unit 10) of an information processing device connected via a LAN. When the wireless microphone holder 15 receives a pairing instruction, it reads out the identification information of the master unit 10 stored in the flash memory 156 (S12). Then, the wireless microphone holder 15 transmits the identification information and the pairing instruction to the wireless microphones 11 to 14 and the master unit 10 (S13). However, the wireless microphone holder 15 does not need to transmit the identification information to the master unit 10.

[0028] The wireless microphones 11 to 14 receive the identification information and the pairing instruction (S21). The master unit 10 also receives the pairing instruction (S31). When the master unit 10 receives the pairing instruction, it transitions to pairing mode (S32). The pairing mode is a mode in which encryption of wireless communication is decrypted and identification information transmitted from another device is received. When the wireless microphones 11 to 14 receive the identification information and the pairing instruction, they broadcast the received identification information (S22). The master unit 10 receives the identification information transmitted by the wireless microphones 11 to 14 (S33). The master unit 10 assigns Dante (registered trademark) channels in the order in which the identification information was received (S34).

[0029] For example, when the parent unit 10 receives identification information from the wireless microphone 11 for the first time, it assigns Dante (registered trademark) channel 1 to the wireless microphone 11. When the parent unit 10 receives identification information from the wireless microphone 12 for the second time, it assigns Dante (registered trademark) channel 2 to the wireless microphone 11. When the parent unit 10 receives identification information from the wireless microphone 13 for the third time, it assigns Dante (registered trademark) channel 3 to the wireless microphone 11. When the parent unit 10 receives identification information from the wireless microphone 14 for the fourth time, it assigns Dante (registered trademark) channel 4 to the wireless microphone 11.

[0030] In this way, the wireless microphones 11-14 and the master unit 10 are connected to each other. Thereafter, the sound picked up by the wireless microphone 11 is transmitted from the master unit 10 to the other device on channel 1 of Dante (registered trademark). The sound picked up by the wireless microphone 12 is transmitted from the master unit 10 to the other device on channel 2 of Dante (registered trademark). The sound picked up by the wireless microphone 13 is transmitted from the master unit 10 to the other device on channel 3 of Dante (registered trademark). The sound picked up by the wireless microphone 14 is transmitted from the master unit 10 to the other device on channel 4 of Dante (registered trademark).

[0031] In this way, the parent unit 10 assigns channels in the order in which they are connected. The user does not need to connect multiple wireless microphones that he or she wants to use in order, but can easily connect the multiple wireless microphones that he or she wants to use to the parent unit 10 by simply pressing the pairing button 151 on the wireless microphone holder 15 once.

[0032] In the wireless microphone system of this embodiment, the identification information and pairing instruction are transmitted to the wireless microphone connected to the wireless microphone holder 15. In other words, the identification information and pairing instruction are not transmitted to a wireless microphone not connected to the wireless microphone holder 15. Therefore, the master unit 10 pairs only with the wireless microphone connected to the wireless microphone holder 15 at the time when the pairing button 151 of the wireless microphone holder 15 is pressed. For example, when the wireless microphones 11 to 13 are connected to the wireless microphone holder 15 and the wireless microphone 14 is not connected, the master unit 10 pairs with the wireless microphones 11 to 13 and does not pair with the wireless microphone 14.

[0033] The wireless microphone system 1 is used in venues of various sizes and events of various scales. The number of wireless microphones required varies depending on the size of the venue and the scale of the event. The event organizer connects the required number of wireless microphones to the wireless microphone holder 15 according to the size of the venue and the scale of the event. After that, when the event organizer presses the pairing button 151, only the wireless microphones connected to the wireless microphone holder 15 at that time are connected to the master unit 10. In this way, the event organizer can easily adjust the number of wireless microphones connected to the master unit 10 according to the size of the venue and the scale of the event.

[0034] In the present embodiment, an example is shown in which four wireless microphones 11 to 14 are connected to the master unit 10, but the number of microphones used is not limited to four. For example, Dante (registered trademark) can transmit audio signals of 64 channels in 100base-TX. Therefore, the master unit 10 can connect a maximum of 64 microphones at the same time. The wireless microphone system 1 can connect more wireless microphones to the master unit 10 than the number of wireless microphones that can be connected to the wireless microphone holder 15 at the same time. The event organizer first mounts the four wireless microphones 11 to 14 on the master unit 10 and presses the pairing button 151 to connect the four wireless microphones 11 to 14 to the master unit 10. After that, the event organizer replaces the four wireless microphones 11 to 14 with other wireless microphones and presses the pairing button 151 again to connect the other wireless microphones to the master unit 10. In this case as well, the master unit 10 assigns Dante (registered trademark) channels in the order in which the identification information is received. For example, if the master unit 10 has already assigned Dante (registered trademark) channels 1 to 4 to the wireless microphones 11 to 14, respectively, it will assign Dante (registered trademark) channel 5 to another wireless microphone that is next connected to the master unit 10.

[0035] Furthermore, the number of wireless microphone holders 15 is not limited to one. The wireless microphone system 1 may include multiple wireless microphone holders 15. The event organizer may mount a wireless microphone in each of the multiple wireless microphone holders 15 and press the pairing button 151 of each of the multiple wireless microphone holders 15. In this case as well, the master unit 10 assigns Dante (registered trademark) channels in the order in which it receives the identification information.

[0036] When the maximum number of connectable channels is reached, the parent unit 10 may refuse to connect to any more wireless microphones. Alternatively, when the maximum number of connectable channels is reached, the parent unit 10 may disconnect the already connected wireless microphones and assign channels to new wireless microphones. For example, the parent unit 10 may disconnect the wireless microphone to which channel 1 is assigned, and assign channel 1 to the newly connected wireless microphone.

[0037] The master unit 10 may also include a mode changeover switch. The master unit 10 may accept, via the mode changeover switch, either a first mode in which a connection with a new wireless microphone is rejected when the maximum number of connectable channels is reached, or a second mode in which a connection with an already connected wireless microphone is terminated and a new microphone is connected. The master unit 10 may also accept a mode changeover instruction via a GUI of an information processing device connected via a LAN.

[0038] Also, the wireless microphone holder 15 may specify whether to add a new wireless microphone or to start over from the assignment of channel 1, depending on how the pairing button 151 is pressed. For example, when the pairing button 151 is pressed for one second, the wireless microphone holder 15 transmits a pairing instruction to the wireless microphone connected at that time and the master unit 10. In this case, the master unit 10 connects a new wireless microphone in addition to the currently connected wireless microphone. On the other hand, when the pairing button 151 is pressed for five seconds, the wireless microphone holder 15 transmits a pairing instruction including an initial setting instruction to the master unit 10. In this case, the master unit 10 disconnects the currently connected wireless microphone, and assigns the wireless microphones connected at that time to new channels starting from channel 1. This allows the event organizer to easily instruct whether to add a wireless microphone or to start over from the beginning.

[0039] 6 is a block diagram showing the configuration of a wireless microphone holder 15A according to a modified example. The flash memory 156 of the wireless microphone holder 15A further stores wireless system information. The other configuration is the same as that of the wireless microphone holder 15, and therefore a description thereof will be omitted.

[0040] The wireless system information is information that indicates the wireless communication system (standard, encryption system, frequency, etc.) to be used. The wireless communication system to be used varies depending on the country or region to which the product is shipped. The master unit 10 and the wireless microphone holder 15 are set in advance at the factory to a wireless communication system suitable for the country or region to which the product is shipped. On the other hand, the wireless microphones 11 to 14 are not set to a wireless communication system at the factory.

[0041] Fig. 7 is a flow chart showing the operations of the wireless microphones 11 to 14, wireless microphone holder 15A, and master unit 10 according to the modified example. Operations common to those in Fig. 5 are given the same reference numerals and will not be described.

[0042] When the wireless microphone holder 15 receives the pairing instruction, it reads out the identification information and the wireless system information (S102). Then, the wireless microphone holder 15 transmits the identification information, the wireless system information, and the pairing instruction to the currently connected wireless microphone (S103). The wireless microphones 11-14 receive the identification information, the wireless system information, and the pairing instruction (S201). The wireless microphones 11-14 set the wireless communication system based on the received wireless system information (S202). As a result, the wireless microphones 11-14 are set to a wireless communication system suitable for the country or region to which the products are shipped, and become able to connect to the parent unit 10.

[0043] In this way, when the wireless microphones 11-14 start to be used, they are set to a wireless communication method suitable for each country or region to which they are shipped. Therefore, there is no need to set a wireless communication method for the wireless microphones 11-14 when they are shipped from the factory. This eliminates the need for manufacturers of wireless microphone systems to set a wireless communication method suitable for each country or region in advance for each of the wireless microphones that are used frequently. Therefore, manufacturers can manufacture and ship wireless microphones without distinguishing between countries or regions to which they are shipped.

[0044] Finally, the description of the present embodiment should be considered as illustrative in all respects and not restrictive. The scope of the present invention is indicated by the claims, not by the above-described embodiments. Furthermore, the scope of the present invention includes the scope equivalent to the claims.
