  FIG. 1 is a configuration diagram of an in-vehicle hands-free device 20. The in-vehicle hands-free device 20 is mounted on an automobile and appropriately connected to at least one mobile phone 30 brought into the passenger compartment 10 by a passenger by wire or wirelessly. The in-vehicle hands-free device 20 in FIG. 1 is connected to a mobile phone 30 by a detachable connection cable 31, that is, by wire. In the passenger compartment 10, the driver's seat 11 is disposed on the right side of the front row, the passenger seat 12 is disposed on the left side of the front row, and the rear seat 13 is disposed on the rear row. The steering wheel 15 is provided in front of the driver seat 11 and is operated by the driver of the driver seat 11.

  The speakers 16a, 16b, 16c, and 16d are speakers of a car audio system mounted in the passenger compartment 10. The front right door, the front left door, the rear left side of the rear seat 13, and the rear right side of the rear seat 13. Equipped with each. Players and tuners such as CDs and MDs of the car audio system are arranged almost at the center of the instruments panel, and reproduced sounds such as music and broadcast programs reproduced by the players and tuners are output from the speakers 16a, 16b, 16c, and 16d. Output all at once. Various voice guidance of the car navigation device is emitted from the speaker 16a.

  The speakers 16 a, 16 b, 16 c, and 16 d also serve as speakers during the hands-free call of the mobile phone 30. When the occupant in the driver's seat 11 makes a hands-free call, the speaker 16a is used. When the occupant in the passenger seat 12 makes a hands-free call, the speaker 16b is used, and the occupant on the left side of the rear seat 13 hands-free. When making a call, the speaker 16c is used, and when the passenger on the right side of the rear seat 13 makes a hands-free call, the speaker 16d is used. When the passenger in the center of the rear seat 13 performs a hands-free call, the speaker 16c or 16d is used. In the period when the sound of the car audio system is being output from each speaker, when the mobile phone 30 receives an incoming call and makes a hands-free call, the output sound from the corresponding speaker is derived from the playback sound of the car audio system. The voice is switched to the voice, and as soon as the hands-free call is completed, the original playback sound is restored.

  The microphones 17a, 17b, 17c, and 17d are disposed in the vicinity of the speakers 16a, 16b, 16c, and 16d in association with the speakers 16a, 16b, 16c, and 16d, respectively. Thus, when the occupant of the driver's seat 11 performs a hands-free call, the microphone 17a is used, and when the occupant of the front passenger seat 12 performs a hands-free call, the microphone 17b is used, and the occupant on the left side of the rear seat 13 is used. When performing a hands-free call, the microphone 17c is used, and when the passenger on the right side of the rear seat 13 performs a hands-free call, the microphone 17d is used. When the passenger in the center of the rear seat 13 performs a hands-free call, the microphone 17c or 17d is used. The heights of the microphones 17a, 17b, 17c, and 17d are preferably approximately the height of the mouth when the occupant corresponding to each of the microphones 17a, 17b, 17c, and 17d is seated in their seat. It may be attached to the ceiling of the passenger compartment 10.

  In the in-vehicle hands-free device 20, each of the speakers 16a, 16b, 16c, and 16d and the microphones 17a, 17b, 17c, and 17d has one pair 16a-17a, 16b-17b, 16c-17c, and 16d-. However, the number of speakers and the number of microphones may not be the same. That is, for example, a fifth microphone may be added to the ceiling in the center in the left-right direction of the rear seat 13, and the fifth microphone may be used for a hands-free call for a passenger in the center in the left-right direction of the rear seat 13. . However, in this case, the occupant at the center in the left-right direction of the rear seat 13 uses the speaker 16c or 16d as the speaker, and is shared with the left-side occupant or the right-hand occupant speaker of the rear seat 13. It will be. Therefore, in this case, the number of microphones is larger than the number of speakers. In the case of sharing, the shared users cannot maintain the confidentiality and quietness of hands-free calls.

  Similarly, the microphones 17b and 17c are replaced with a single microphone disposed in the center in the front-rear direction of the passenger compartment 10 and on the left side, and a microphone for hands-free communication between the passenger in the passenger seat 12 and the left passenger in the rear seat 13 is used. May be shared. Therefore, in this case, the number of microphones is smaller than the number of speakers.

  The in-vehicle hands-free device 20 includes speakers 16a, 16b, 16c, and 16d and microphones 17a, 17b, 17c, and 17d as elements, a management unit 21, a key input unit 22, a memory unit 23, a call control unit 25, and voice. The input / output switching unit 27 and the communication line 29 are included as elements. A user who gets into the passenger compartment 10 connects the mobile phone 30 carried by himself / herself to the call control unit 25 of the in-vehicle hands-free device 20 via the connection cable 31 so as to be freely disconnected. A plurality of connection locations of the connection cable 31 to the mobile phone 30 can be prepared in association with each seat in the passenger compartment 10, or only one location in the passenger compartment 10 may be centrally arranged. In the in-vehicle hands-free device 20, the mobile phone 30 is detachably connected to the call control unit 25 by a connection cable 31, but is connected to the call control unit 25 by short-range wireless communication such as Bluetooth or wireless LAN. It may be like this. A call line 29 connects the call control unit 25 and the voice input / output switching unit 27.

  In the in-vehicle hands-free device 20, the user operates the key input unit 22 or a predetermined key of the mobile phone 30 during a period in which the mobile phone 30 is connected to the call control unit 25 via the connection cable 31. Thus, it is possible to appropriately switch between a hands-free call and a call used by holding the mobile phone 30. In addition, during the hands-free call, the user disconnects the connection cable 31 from the call control unit 25 or the mobile phone 30 and disconnects the connection between the call control unit 25 and the mobile phone 30, so It is also possible to change to a call that is used by gripping.

  The key input unit 22 is arranged in the instrument panel portion on the left front side of the driver's seat 11 and is appropriately operated by the passenger in the driver's seat 11 or the passenger seat 12 so that the user inputs various settings and instructions related to hands-free calling. It can be done. The key input unit 22 may be a remote controller. The key input unit 22 may also be used as a fixed or remote control key input unit of the car audio system in the passenger compartment 10. The call control unit 25 relays a call signal between the voice input / output switching unit 27 and the mobile phone 30 when the mobile phone 30 is connected to the mobile phone 30 via the connection cable 31. The information transmission signal to 21 is relayed.

  When the mobile phone 30 receives an incoming call, the management unit 21 inputs the telephone number of the other party who has called the mobile phone 30 from the mobile phone 30 via the call control unit 25 and also provides key input. A user instruction from the unit 22 is input. The management unit 21 creates or updates predetermined hands-free device selection information based on these inputs, and records the latest hands-free device selection information in the nonvolatile memory unit 23.

  The hands-free device selection information is a correspondence between caller information such as a telephone number, name, and / or group and a hands-free device (collectively referred to as “hands-free device” including a speaker and a microphone as appropriate). This information is included. The information transmitted from the other party's telephone to the mobile telephone 30 is only the other party's telephone number in the outgoing telephone number notification service, but the typical mobile telephone 30 is equipped with an address book. The user may register a correspondence between a telephone number and the name, group, company name, etc. in the address book. For example, the management unit 21 receives the address book information of the mobile phone 30 from the mobile phone 30 in advance, and incorporates the address book information into information that is only associated with the telephone number and the hands-free device. Selection information can be recorded in the memory unit 23.

  The management unit 21 receives caller information from the mobile phone 30 as soon as the mobile phone 30 receives an incoming call. Then, the hands-free device selection information is read from the memory unit 23, the hands-free device associated with the caller information is found, and an instruction to connect the call control unit 25 to the found hands-free device is sent to the voice input / output switching unit. Take out to 27. The voice input / output switching unit 27 connects the mobile phone 30 to the hands-free device in accordance with a connection instruction from the management unit 21.

  Assume that the owner of the mobile phone 30 is A, and that B, C, and D are in the cabin as well as A. In addition, it is assumed that A, B, C, and D are seated on the driver's seat 11, the passenger seat 12, the left of the rear seat 13, and the right of the rear seat 13, respectively. When the caller information is, for example, a telephone number or a name, the caller information includes a telephone number relating to A, a telephone number relating to B, a telephone number relating to C, and a telephone number relating to D. Exists.

  When the caller information notified from the mobile phone 30 to the management unit 21 is the phone number related to A, the speaker 16a and the microphone 17a are selected as hands-free devices in the current hands-free call. When the caller information notified from the mobile phone 30 to the management unit 21 is the telephone number related to B, the speaker 16b and the microphone 17b are selected as hands-free devices in the current hands-free call. When the caller information notified from the mobile phone 30 to the management unit 21 is the telephone number related to C, the speaker 16c and the microphone 17c are selected as hands-free devices in the current hands-free call. When the caller information notified from the mobile phone 30 to the management unit 21 is the phone number related to D, the speaker 16d and the microphone 17d are selected as hands-free devices in the current hands-free call.

  When the caller information is a name or group other than a telephone number, for example, the caller information includes a name and group related to A, a name and group related to B, a name and group related to C, and a name related to D There are things about names and groups. In addition, the owner A includes the name and group related to B, the name and group related to C, and the name and group related to D in addition to the name and group related to himself / herself in the address book of the mobile phone 30 owned by himself / herself. Assume that the correspondence between each telephone number and name or group is registered.

  When the caller information notified from the mobile phone 30 to the management unit 21 is the name or group related to A, the speaker 16a and the microphone 17a are selected as hands-free devices in the current hands-free call. When the caller information notified from the mobile phone 30 to the management unit 21 is a name or group related to B, the speaker 16b and the microphone 17b are selected as hands-free devices in the current hands-free call. When the caller information notified from the mobile phone 30 to the management unit 21 is the name or group related to C, the speaker 16c and the microphone 17c are selected as hands-free devices in the current hands-free call. When the caller information notified from the mobile phone 30 to the management unit 21 is a name or group related to D, the speaker 16d and the microphone 17d are selected as hands-free devices in the current hands-free call. .

  There are various specific examples of the hands-free device selection information creation method. The first hands-free device selection information creation method is performed during a hands-free call period. In the first hands-free device selection information creation method, when the mobile phone 30 receives an incoming call, the caller number is notified from the mobile phone 30 to the management unit 21. The management unit 21 displays the notified telephone number itself on a predetermined display (not shown), or based on address book information received in advance from the mobile phone 30, the name and group corresponding to the telephone number Or the like, and display it on the display.

  An occupant in charge of creating hands-free device selection information (usually a driver when the vehicle is stopped) looks at the telephone number, name or group displayed on the display, and corresponds to them as speakers 16a, 16b. , 16c, 16d and one of the microphones 17a, 17b, 17c, 17d. In the in-vehicle hands-free device 20, the speaker and the microphone are 1: 1 and are in the relationship 16 a-17 a, 16 b-17 b, 16 c-17 c, and 16 d-17 d, so if one of the speaker and the microphone is specified, the other The other designation may be omitted. The input at the key input unit 22 for designating a hands-free device is, for example, a numeric keypad input associated with the position of each speaker 16a, 16b, 16c, 16d (eg, the driver seat position is # 1, the passenger seat position is # 2, ...) may be performed. In this way, hands-free device selection information is created as association information between the caller information and the hands-free device. For the hands-free device selection information once created, the user then operates the key input unit 22 again to add hands-free device selection information related to the new caller information as appropriate, or to register registered callers. It is possible to delete or change the hands-free device selection information related to the information.

  The second hands-free device selection information creation method is a partial modification of the first hands-free device selection information creation method. In the first creation method, new caller information is displayed on the display, and the creator of the hands-free device selection information specifies the hands-free device to be associated with the display on the display. On the other hand, in the second hands-free device selection information creation method, when there is an unregistered hands-free incoming call on the mobile phone 30, the management unit 21 causes the voice input / output switching unit 27 to switch the mobile phone 30. An instruction to connect to a default hands-free device, for example, the speaker 16a and the microphone 17a is given to the voice input / output switching unit 27. The creator of the hands-free device selection information designates a device as hands-free based on the voice of the other party from the speaker 16a and the microphone 17a, thereby creating hands-free device selection information. The created hands-free device selection information is stored in the memory unit 23 as in the case of the first hands-free device selection information creation method.

  The third hands-free device selection information creation method is performed during a period when there is no call. The user inputs both the telephone number and the hands-free device associated therewith from the key input unit 22, whereby hand-free device selection information is created and stored in the memory unit 23.

  The hands-free device selection information can be updated not only during the non-execution period of the hands-free call but also during the implementation period. The hands-free device selection information during the hands-free call non-execution period can be updated on the display device by operating the key input unit 22 as in the first hands-free device selection information creating method. In that case, the data to be updated is called up by the display. In the update of the hands-free device selection information during the hands-free call execution period, the key input unit 22 is operated during the period in which the mobile phone 30 is connected to a predetermined hands-free device for the hands-free call. The hands-free device associated with the caller information related to the hands-free call is changed by operating the key input unit 22. When there is a change, the management unit 21 issues an instruction to the voice input / output switching unit 27 to immediately switch the mobile phone 30 from the hands-free device before the update to the hands-free device after the update, and also selects the hands-free device in the memory unit 23. Update the information to reflect the update.

  FIG. 2 is a configuration diagram of an in-vehicle hands-free device 20 that can handle hands-free calling of a plurality of mobile phones. Differences from those in FIG. 1 will be described. In the call control unit 25, a plurality of mobile phones can be appropriately connected for hands-free calling. In FIG. 2, the three mobile phones 30a, 30b, and 30c are connected to connection cables 31a and 31b, respectively. , 31c to the call control unit 25 in a separable manner. The call control unit 25 and the voice input / output switching unit 27 are connected to each other by call lines 29a, 29b, and 29c corresponding to the connection cables 31a, 31b, and 31c, respectively.

  When there is an incoming call to a certain mobile phone, the call control unit 25 sends the caller information from the mobile phone to the management unit 21 and which of the connection terminals in the call control unit 25 is connected to the mobile phone. Information about whether or not there is is notified to the management unit 21. The connection terminals of the call control unit 25 to which the mobile phones 30a, 30b, and 30c are connected correspond to the call lines 29a, 29b, and 29c, respectively. As for the hands-free device as one side of the hands-free call connection in the voice input / output switching unit 27, the management unit 21 stores the hands-free device selection information in the memory unit 23 in the same manner as the in-vehicle hands-free device 20 in FIG. The hand-free device corresponding to the caller information is searched for, and an instruction to select it is given to the voice input / output switching unit 27. As the other side of the hands-free call connection in the voice input / output switching unit 27, the management unit 21 determines the call lines 29a, 29b, and 29c connected to the voice input / output switching unit 27 based on the connection terminals from the call control unit 25. Then, an instruction to select the determined call lines 29a, 29b, 29c is issued to the voice input / output switching unit 27. As a result, the voice input / output switching unit 27 connects the mobile phone that has received the call to the handsfree device near the occupant who performs the handsfree call, and the handsfree call is performed.

  Assume that the owners of the mobile phones 30a, 30b, and 30c are A, B, and C, respectively. Assume that A, B, and C are seated to the left of the driver's seat 11, the passenger seat 12, and the rear seat 13, respectively. In a normal case, the telephone number, name, group, or the like that the management unit 21 receives from the mobile phone 30a in response to an incoming call to the mobile phone 30a is related to A, and the speaker 16a and the microphone 17a are hands of this time. Selected as a hands-free device for free calls. The telephone number, name, or group that the management unit 21 receives from the mobile phone 30b in response to an incoming call to the mobile phone 30b is related to B, and the speaker 16b and the microphone 17b are hands that can be used in this hands-free call. Selected as a free device. The telephone number, name or group that the management unit 21 receives from the mobile phone 30c in response to an incoming call to the mobile phone 30c is related to C, and the hands of the speaker 16c and the microphone 17c in this hands-free call Selected as a free device.

  However, in the address book of the mobile phone 30a, in addition to the phone number, name, and group related to A, the phone number, name, and group related to B and C as others may be registered for each other person. When the telephone number, name, or group that the management unit 21 receives from the mobile phone 30a in response to an incoming call to the telephone 30a is related to B or C, the speaker 16b and the microphone 17b, or the speaker 16c, respectively. And the microphone 17c are selected as hands-free devices, respectively, and the selected hands-free device and the mobile phone 30a are connected by telephone. The same applies to the case where telephone numbers, names and groups related to persons other than B and C are registered in the address book of the cellular phones 30b and 30c.

  In the in-vehicle hands-free device 20 shown in FIG. 2, a hands-free call for a plurality of mobile phones can be performed simultaneously as long as the hands-free call is not the same. If a hands-free device that is already being used for a hands-free call on another mobile phone is a hands-free device for a later-received mobile phone, the subsequent incoming call is a hands-free call. The user is rejected, and the user disconnects the mobile phone that has arrived later from the call control unit 25 and makes a call on the mobile phone itself.

  FIG. 3 is a configuration diagram of the hands-free device 40. An example of the hands-free device 40 is the in-vehicle hands-free device 20 (FIGS. 1 and 2). The hands-free device 40 is typically provided in a passenger compartment such as a passenger car, a bus, and a railway vehicle, but is not limited to a vehicle-mounted type. The hands-free device 40 may be deployed in a predetermined building or site. The hands-free device 40 is configured to connect at least one mobile communication terminal device 50 as appropriate for hands-free calling. The hands-free device 40 includes microphones 41a, 41b, 41c,. 42a, 42b, 42c,..., A notified means 43 and a connecting means 44 are provided. The management means 47 will be described later.

  A plurality of microphones 41a, 41b, 41c,... And speakers 42a, 42b, 42c,... Used for hands-free calling are arranged in a predetermined space apart from each other. When the mobile communication terminal device 50 connected to the hands-free device 40 receives an incoming call, the notified means 43 sends an incoming call to the mobile communication terminal device 50 and caller information from the mobile communication terminal device 50. Be notified. The connection means 44 selects one of each of the microphones 41a, 41b, 41c,... And the speakers 42a, 42b, 42c,. The speaker and the microphone are connected to the mobile communication terminal device 50 for a hands-free call this time.

  An example of the microphones 41a, 41b, 41c,... Is speakers 16a, 16b, 16c, 16d. An example of the speakers 42a, 42b, 42c,... Is a microphone 17a, 17b, 17c, 17d. For example, one speaker and one microphone may constitute a pair, and each pair of speaker and microphone may be in charge of a hands-free call of a person existing in substantially the same section. However, regarding a hands-free call, it is assumed that the assigned division of one speaker corresponds to the assigned division of a plurality of microphones, and vice versa.

  In the in-vehicle hands-free device 20 as an example of the hands-free device 40, the speakers 16a, 16b, 16c, and 16d also serve as the speakers of the car audio system, but the speakers 42a, 42b, 42c,. • may be dedicated to hands-free calls that do not double as speakers for car audio systems. An example of the mobile communication terminal device 50 is the mobile phone 30, but the mobile communication terminal device 50 may be a device such as a PDA other than the mobile phone.

  Thus, when there is an incoming call to the mobile communication terminal device 50, a speaker and a microphone in charge of a hands-free call in a predetermined range in the space are transferred to the mobile communication terminal according to the other party who has called the mobile communication terminal device 50. Since a call connection is made to the terminal device 50 and a hands-free call is performed from the predetermined speaker and microphone, it is possible to suppress inconvenience to others and to maintain the confidentiality of the content of the call within an appropriate range. it can.

  Various specific modes of the hands-free device 40 will be described.

  The caller information is, for example, information related to the telephone number, name and / or group of the other party. In the caller telephone number notification service, only the telephone number of the other party who made the call is notified from the other party's telephone to the mobile communication terminal apparatus 50, but the mobile communication terminal apparatus 50 may be equipped with an address book. is there. A user may register a name, a group, and others in association with each telephone number in the address book. By using the address book information, the management unit 21 can determine the speaker and microphone to be selected for the current hands-free call not only from the telephone number but also from the name, group, and others.

  The hands-free device 40 can be additionally equipped with management means 47. The management unit 47 creates and stores and manages hands-free device selection information in which caller information is associated with a speaker and a microphone for hands-free calling based on a user instruction. The connection means 44 selects microphones 41a, 41b, 41c,... And speakers 42a, 42b, 42c,... For the current hands-free call based on the hands-free device selection information.

  Note that the speaker selected for this hands-free call is closest to the current hands-free caller, but if this hands-free caller is near the boundary of the speaker's area Suppose that a plurality of speakers may be selected.
