The present invention relates to a call system capable of controlling data output and a call device used in the call system.

  In recent years, the technological innovation of mobile terminal devices such as mobile phones has been remarkable, and multifunctional and highly functional such as communication functions such as Internet connection, e-mail functions, games, music players, FM broadcast reception, TV broadcast reception, etc. Is progressing.

  As is well known, in terrestrial digital broadcasting, broadcasting using a transmission band of 1 or 3 segments is planned mainly for receivers with high portability. Service is planned for high receivers.

  As described above, the mobile phone has not only an original call function but also a media playback function such as music playback and a broadcast receiver. As a playback function of audio media, a stereo earphone microphone or a stereo Speakers and other stereos are also being developed.

  Also, while mobile phones are becoming multimedia terminals, the manners of using mobile phones will be set to manner mode so that no sound will be emitted to the outside during use in front of the public, and earphone microphones will be used. Good manners are also taking root.

  Under such circumstances, various mobile telephones with music playback functions such as the following first to third apparatuses have been proposed.

  The first device is a mobile phone device that can be used as a headphone stereo when not used as a telephone, can smoothly respond to an incoming call by remote control when an incoming call is received, and interrupts music by the incoming call response ( For example, see Patent Document 1).

  The second device is a mobile phone with a headphone stereo, and when the telephone unit receives an incoming call even when the headphone stereo unit is in operation, the mobile phone plays the earphone with priority over the playback sound of the headphone stereo. (For example, see Patent Document 2).

  The third device is a mobile phone with a music playback function in which a ring tone is superimposed on the music of the earphone when receiving an incoming call so that the incoming call of the mobile phone can be confirmed even during music playback.

In addition, card systems and position information providing apparatuses using ID tags including ID information (data) have been proposed.

  For example, in a contactless card system using an ID tag, when collision occurs, the number of times of communication for each ID tag is reduced, and the time until ID data is collected from each ID tag is shortened. A card system with improved processing speed has been proposed.

  In addition, a position information providing apparatus that provides position information of a mobile object to which a wireless ID tag is attached has been proposed by using a plurality of wireless ID readers arranged at predetermined locations.

<First Embodiment>
FIG. 1 is a block configuration diagram showing a first embodiment of a mobile phone as a call device according to the present invention.

  The cellular phone 1 according to the present embodiment employs, as an example, a configuration that includes a broadcast receiving unit in addition to a normal telephone communication unit.

  The mobile phone 1 in FIG. 1 includes a telephone call unit 100, a broadcast receiving unit 200, and a sound / display control system 300 as main components.

  The display / sound control system 300 includes a display unit 301, a voice switching unit 302 as a sound control unit, a control unit 303 as a call and sound output control unit, an ID (recognition information) reading unit 304 as a recognition information detection unit, a microphone. 305, a speaker unit 306, and a stereo earphone unit 307.

  The telephone call unit 100 includes a mobile phone antenna unit 101, a transmission / reception unit 102, and a call processing unit 103, and has a function for calling the call voice 104 with a partner terminal using the microphone 305 and the speaker unit 306. Have.

  The telephone call unit 100 is controlled by the control unit 303, and the user interface is displayed by the control unit 303 using the display unit 301.

  The broadcast receiving unit 200 includes a broadcast receiving antenna unit 201, a tuner unit 202, a demodulation processing unit 203, and a decoding unit 204.

  The broadcast receiving unit 200 receives broadcast waves via the broadcast receiving antenna unit 201, matches the channels with the tuner unit 202, demodulates the received waves with the demodulation processing unit 203, and demodulates the received waves with the decoding unit 204. The broadcast audio signal 205 and the broadcast video signal 206 are decoded.

  The broadcast video signal 206 is displayed on the display unit 301, and the broadcast audio signal 205 is input to the audio switching unit 302.

  The display unit 301 is configured by a liquid crystal display (LCD) or the like, and displays video corresponding to the broadcast video signal 206 under the control of the control unit 303.

  Under the control of the control unit 303, the audio switching unit 302 switches between the call audio signal 104 by the call processing unit 103 of the telephone call unit 100 and the broadcast audio signal 205 by the decoding unit 204 of the broadcast receiving unit 200, and the speaker unit 306, Alternatively, the data can be output to the stereo earphone unit 307 including the R-channel earphone 307a and the L-channel earphone 307b.

  The earphone unit 307 of this embodiment is a stereo earphone composed of an R-channel earphone 307a and an L-channel earphone 307b. For example, a predetermined position of each earphone in which a speaker is built, for example, FIG. As shown, an ID portion 307a (307b) is provided on the back of the earphone.

  In the case of a stereo earphone as in this embodiment, different ID information (recognition information) is given to the ID sections 307a and 307b provided in the left and right earphone speaker sections.

  Then, under the control of the control unit 303, the voice switching unit 302 sends the call audio signal 104 to the earphone speaker side to which the ID detected by the ID reading unit 304 is assigned, and the out-call audio signal to the other earphone speaker side. Broadcast audio signal 205 is output.

  The control unit 303 detects an incoming call when the telephone communication unit 100 receives an incoming call, and enters a normal incoming call state when the broadcast receiving unit 200 is not receiving a broadcast for viewing. Wait for connection event.

  When the broadcast receiving unit 200 receives a broadcast wave and is watching a broadcast program using the display unit 301 and the earphone unit 307 when detecting an incoming call, the control unit 303 takes the incoming call off-hook. Then, when the call state is entered, the ID reading unit 304 is operated to start ID reading.

  If the ID reading unit 304 does not read the ID, the control unit 303 continuously outputs the broadcast audio signal 205 to the earphones 307a and 307b of the earphone unit 307 via the audio switching unit 302.

  As described above, when the ID reading unit 304 reads the ID, the control unit 303 controls the voice switching unit 302 to transmit the call voice signal to the earphone speaker side corresponding to the read ID in the earphone unit 307. 104 is output, and the broadcast audio signal 205 is output to the other earphone speaker side.

  In addition, when the ID reading unit 304 obtains ID information of the ID unit arranged in one earphone speaker, the control unit 303 outputs the call voice signal 104 to one speaker in an output state and to the other speaker. Can be configured so that the volume is controlled to be in a non-output state or a low output state with respect to one speaker.

  When the left and right earphones 307a and 307b of the earphone unit 307 have different IDs, the audio signal is reproduced as described above. When the IDs are the same, the broadcast audio signal 205 and the call audio signal 104 are simply Switching operation.

  The ID reading unit 304 periodically performs a reading operation thereafter, and when the ID cannot be detected, the broadcast audio signal 205 is output to the earphones 307a and 307b of the earphone unit 307.

  When the ID reading unit 304 continues to detect ID information for a predetermined time or longer, the control unit 302 locks the operation of the voice switching unit 302.

  In addition, when the voice switching unit 302 detects different recognition information while being locked, the control unit 302 unlocks the sound control unit.

  In addition, when the volume adjustment unit (not shown) is operated during a call and the ID reading unit 304 is in the ID information detection state, the control unit 303 adjusts the volume of the call voice, and the ID reading unit 304 When the ID information is not detected, the volume of the broadcast sound is adjusted.

  At this time, the control unit 303 adjusts the volume of the call voice when the voice switching unit 302 is locked.

  Further, the control unit 303 stops the display of the display unit 301 while the ID reading unit 304 is detecting ID information during a call.

  The ID reading process in the ID reading unit 304 is such that the ID reading unit 304 detects the ID information of the ID units 308a and 308b in which the IDs are indicated, and recognizes the ID. There are various methods such as using a camera for the ID part and using a two-dimensional barcode for the ID part, constructing the ID part with colors and performing color recognition, and using a non-contact IC card. May be adopted.

  More specifically, for example, ID units 308a and 308b are provided on the back of the earphone unit as shown in FIG. 2, and ID reading is performed around the speaker of the telephone body 10 as shown in FIG. When the unit 304 is installed, when the user receives an incoming call while listening to the broadcast using the earphone unit 307 and enters a talking state, the user keeps the earphones 307a and 307b in the vicinity of the ear, as shown in FIG. As shown in the figure, the ID reading unit 304 can detect the ID information of the ID unit 308a attached to the R-channel earphone 307a when the phone body 10 is held over the ear in the same manner as in normal use (if it is applied). The call voice can be heard from the R channel over which the telephone body 10 is held, and the broadcast voice that has been viewed up to now can be heard from the L channel.

  From this state, as shown in FIG. 4 (c), when the telephone body 10 is moved away from the ear, broadcast sound can be heard from both earphone channels, and only the broadcast can be viewed as necessary even in a call state. It becomes possible to do.

  Further, even when the user changes the phone body 10 from the state shown in FIG. 4C to the state shown in FIG. 4A or FIG. 4B, the earphone attached to the ear that is held up. Because the voice can be heard, it is possible to make a call in the same way as a normal call without wearing the earphone, and the broadcast audio signal can always be heard from the earphone on the other side. It becomes possible to do.

  Next, the operation according to the above configuration will be described with reference to the flowchart of FIG.

  FIG. 5 is a flowchart showing the voice switching operation of the mobile phone according to the first embodiment.

  For example, if an incoming call is received in step ST0 while receiving a broadcast wave and viewing the broadcast, it is determined in step ST1 whether the TV is being viewed.

  In step ST1, if the TV is not being viewed, the process proceeds to a normal incoming call process in step ST2.

  In step ST1, when the user is watching TV, if the user performs a call start operation, the process proceeds to step ST3 to start the call.

  Next, in step ST4, ID reading is started.

  In step ST5, it is determined whether an ID is detected.

  If no ID is detected as a result of ID reading in step ST5, the broadcast audio signal 205 is selected as the audio output in the process of step ST6.

  After that, in step ST7, a waiting state is established for a certain time, ID reading is started again in step ST4, and this operation is repeated.

  If the ID is detected in step ST5, the voice switching unit 302 is used to output the call voice to the channel corresponding to the ID in step ST8.

  When the voice output unit has only one ID, all outputs are call voice outputs. When the audio output unit has a plurality of IDs (for example, two channels), the call audio is output only for the channel corresponding to the read ID, and the other outputs the broadcast audio.

  After waiting for a certain time in step ST9, it is determined in step ST10 whether the output time to the same channel has exceeded n seconds.

  Here, if the output time to the same channel exceeds n seconds, it is considered that the user's conversation posture is stable, the voice switching unit is locked in step ST11, and the notification sound is beaten to the user in step ST12. Notify that the switching unit has been locked.

  If it does not exceed n seconds in step ST10, since the user's call posture is not stable as at the start of the call, there is a possibility that the phone may still be switched. Therefore, the process proceeds to step ST4 without locking the voice switching unit 302, and ID reading is started again.

  If it is determined in step ST10 that it has exceeded n seconds and the voice switching unit 302 is locked, the voice switching unit 302 is locked until the unlocking condition is generated in step ST13. As a condition for unlocking, it is assumed that one of the conditions “when a different ID is read” or “when an ID has not been detected for a certain period of time” occurs.

  If the unlocking condition occurs, the ID reading is started again in step ST4, and the same processing is performed.

  When a call end event occurs as shown in step ST15 due to a user operation or a call partner operation, the process proceeds to step ST16 to output a broadcast reception voice, and returns to the state before the incoming call.

  Further, when outputting the call voice in step 3T8, the voice switching unit 302 has a voice output unit having an ID different from the corresponding ID, and the other outputs a broadcast voice signal. By adjusting the volume of the audio signal or the gain value and setting the volume of the call audio signal to be higher than that of the broadcast audio, it is possible to create a situation that is easy for the user to hear.

  In addition, when the volume operation is performed by the user in the above state, it is assumed that the user is mainly listening to the call voice when the voice switching unit is locked, so only the volume of the call voice is operated. By improving the convenience.

  Further, in the same case, it is possible to operate more easily by adjusting the volume of the broadcast audio signal and the call audio signal in inverse proportion.

  Further, when the ID reading unit 304 detects the ID, the user is holding the telephone body over his / her ear. Therefore, by turning off the display unit 301, the terminal can be used during a call during broadcast reception. It becomes possible to reduce the power consumption.

  As described above, according to the first embodiment, it is possible to switch the audio signal output during the normal use operation without requiring any special operation by the user. Thus, it becomes possible to provide a mobile phone that can listen to voice signals of services other than calls simultaneously with call voices.

  Further, in the mobile phone according to the first embodiment, the ID of the ID portion arranged in the earphone speaker is read during a call, and the call body is output to the speaker having the ID. When you are on the ear that is wearing the phone, you can hear the voice of the call, and when you release the phone from the ear, you will hear the off-call voice. Therefore, it is possible to talk in a natural state.

  Also, if you are using stereo earphones, you can hear the call voice from the earphone in the direction that the phone is attached and the other earphone can hear the voice outside the call. It becomes possible to hear.

  In addition, when ID is detected, the telephone call is placed on the ear, so that it is possible to reduce power consumption by turning off the screen display as a result.

  In addition, when the ID is continuously detected for a certain period of time, the voice switching means is locked and the user is notified by sound, which is convenient and the call can be continued even if the terminal is removed from the ear. .

When a different ID is detected even in that state, that is, when the terminal body is placed on the other ear, the lock is released and the call voice is heard from the ear that is attached to the terminal body. Even when a call is made while switching, the call can be made in a natural state.
