It is a perspective view of the system configuration | structure figure of Example 1 which concerns on embodiment of this invention. Example 1 3 is an explanation screen of a call posture displayed on a wristwatch display unit according to the first embodiment. 10 is another explanatory screen of a call posture displayed on the wristwatch display unit in the first embodiment. . FIG. 10 is still another explanatory screen of the call posture displayed on the wristwatch display unit in the first embodiment. FIG. 1 is a block diagram of Example 1. FIG. It is a flowchart which shows the function of the wristwatch type transmission / reception apparatus in Example 1. FIG. It is a flowchart which shows another function of the wristwatch-type transmission / reception apparatus in Example 1.

  FIG. 1 is a perspective view of a system configuration diagram of Example 1 according to the embodiment of the present invention. The first embodiment constitutes a system including a mobile phone 2 and a wristwatch type transmitter / receiver 4. The cellular phone 2 is configured as a so-called smartphone having a wristwatch display unit 6 having a GUI (graphical user interface) function. An operation unit 8 such as a numeric keypad is displayed on the wristwatch display unit 6, and a GUI operation is performed in response to a finger touch or slide on the wristwatch display unit 6. The infrared light emitting units 10 and 12 and the infrared light receiving unit 12 constitute a proximity sensor that detects that the mobile phone 2 is applied to the ear. The mobile phone 2 further includes an earphone 16, a microphone 18, and a video phone inner camera 20. Although not shown in FIG. 1, the mobile phone 2 has a rear main camera on the back side of the wristwatch display unit 6, and a wristwatch type transmitter / receiver 4 by a radio wave 22 of a short-range communication system such as Bluetooth (registered trademark). And short-range communication is possible. The mobile phone 2 further has a speaker for generating a ringtone or a videophone. For the sake of distinction, the speaker that is listened to the ear is referred to as “earphone 16” as described above. Yes.

The wristwatch type transmitter / receiver 4 includes a wristwatch body 26 and a belt portion 28. The wristwatch body 26 is provided with a wristwatch display unit 30 using a reflective liquid crystal, and performs various displays described later along with a normal time display. The wristwatch display unit 30 is of a touch panel type, has a 30a by touching the display unit, and can operate the wristwatch type transmitter / receiver 4. Watch body 26
Is provided with a speaker 32 for a transmitter / receiver, and by a short-distance communication with the mobile phone 2, a call can be made while looking at the wristwatch-type transmitter / receiver 4 even when the mobile phone 2 is placed in a pocket, for example. . The microphone for the transmitter / receiver will be described later. The wristwatch body 26 is further provided with a camera unit 34 to capture an image of the face of the wristwatch display unit 30, and the other party's face is displayed on the wristwatch display unit 30. .

  The wristwatch body 26 is provided with a cartilage conduction vibration source 36 composed of a piezoelectric bimorph element or the like, and transmits the vibration for cartilage conduction from the back side of the wristwatch body 26 to the wrist. The belt portion 28 is also provided with cartilage conduction vibration sources 38 and 40 made of similar piezoelectric bimorph elements and the like, and transmits vibration for cartilage conduction from the back side of the belt portion 28 to the wrist. The belt portion 28 is provided with a conduction band 41 made of a material having a similar acoustic impedance to the wrist, and the cartilage conduction vibration sources 38 and 40 are disposed in the conduction band 41 so that vibrations are transmitted in the conduction band. 41 is configured to be transmitted. In this manner, the wristwatch 4 transmits vibration for cartilage conduction to a wide area around the wrist. The configuration for transmitting vibrations from a wide range around the wrist is effective in absorbing individual differences in suitable positions for transmitting vibrations and positional deviations while the wristwatch-type handset 4 is being worn. Further, by transmitting vibration from a wide area around the wrist, vibration for cartilage conduction can be transmitted to the hand more effectively.

  Here, cartilage conduction will be described. Cartilage conduction is a phenomenon discovered by the present inventor, and is a phenomenon in which the cartilage surface of the external auditory canal vibrates due to vibration transmitted to the cartilage around the entrance to the external ear canal such as tragus and generates air conduction sound in the external auditory canal. . The air conduction sound generated in the ear canal travels further back in the ear canal and reaches the eardrum. Thus, the main part of the sound heard by cartilage conduction is the sound heard through the tympanic membrane. However, what is heard through the eardrum is not a sound that enters the ear canal from outside the external auditory canal, but a sound that is generated inside the ear canal.

  Each of the cartilage conduction vibration sources described above also serves as a vibration source of the incoming vibrator, and vibrates when the incoming signal is transmitted by short-range communication with the mobile phone 2 and notifies the incoming by transmitting the vibration to the wrist. As will be described later, the cartilage conduction vibration source is vibrated in the frequency range of the audio signal (frequency centered at 1000 Hz) during cartilage conduction and causes a vibration sensation so that unpleasant vibration is not sensed by the wrist. (For example, 20 Hz or less) is cut and transmitted to the wrist. On the other hand, when vibrating as an incoming vibrator, it is vibrated around a frequency (for example, 20 Hz or less) that causes vibration, and the audible frequency range is cut so that it cannot be heard by others.

  The belt portion 28 is provided with a tightening mechanism 42, which loosens the belt portion 28 when the wristwatch type transmitter / receiver 4 is attached / detached, and tightens in a normal wearing state. The tightening mechanism 42 further secures the cartilage conduction to the wrist by tightening the belt 28 slightly tightly in a range where there is no pain or discomfort from the normal state. Switching from the normal state to the cartilage conduction state by the tightening mechanism 42 can be performed by a touch panel operation by pressing a switch unit 44 displayed on the wristwatch display unit 30. Since the operation of pressing the switch unit 44 is an operation in a direction in which the wristwatch body 26 is pressed against the wrist, the operation of bringing the cartilage conduction vibration source 36 into close contact with the wrist more reliably. When cartilage conduction is sufficient in the normal wearing state, it is possible to talk without pressing the switch 44.

  The belt unit 28 is further provided with a variable directivity microphone 46 for a transmitter / receiver. In the above videophone state, as shown by the arrow 48, the variable directivity microphone 46 is set to have directivity on the back side of the hand so as to pick up sound from the front of the wristwatch display unit 30. On the other hand, when a call is made by cartilage conduction, the variable directivity microphone 46 switches the directivity so as to pick up the voice from the palm side of the hand (usually the left hand) in which the wristwatch type handset 4 is fitted as shown by the arrow 48. Therefore, it is possible to make a call with the attitude described below. The belt portion 28 is provided with vibration isolation bands 52 and 54 made of materials having different acoustic impedances so that vibrations from the cartilage conduction vibration source softs 36, 38 and 40 are not transmitted to the variable directivity microphone 46. I have to. An antenna 56 of the short-range communication unit is provided along the belt unit 28 so as to wrap around the wrist.

  FIG. 2 is an explanatory screen of the call posture displayed on the wristwatch display unit 30 in the first embodiment shown in FIG. This screen is displayed every time the power switch of the wristwatch type transmitter / receiver 4 is turned on, but can be set not to be displayed when it is complicated. FIG. 2A illustrates a call posture during a videophone call, and illustrates a posture in which a videophone call is made while looking at the wristwatch display unit 30 while the mobile phone 2 is placed in a pocket, for example. At this time, the directivity of the variable directivity microphone 46 is directed toward the back of the hand as indicated by an arrow 48 in FIG.

  FIG. 2B illustrates the posture of the cartilage conduction call. The index finger of the hand (for example, the left hand) in which the wristwatch type transmitter / receiver 4 is fitted is placed on the tragus (the ear cartilage) of the ear (for example, the left ear) on the same side. The call posture by the cartilage conduction applied to is shown. At this time, if the ear hole is not blocked with a finger, the sound can be heard by cartilage conduction in a state where an external sound can be heard. In addition, if the tragus is pushed strongly to close the ear hole, the sound of cartilage conduction can be heard with a louder sound due to the effect of closing the ear canal. With such a talking posture, the vibration for cartilage conduction introduced from the wrist is transmitted to the index finger, and the vibration is transmitted to the tragus (ear cartilage), so that the other's voice can be heard by good cartilage conduction. At the same time, as shown by an arrow 50 in FIG. 1, it is possible to convey to the opponent one's own voice picked up by a microphone whose directivity is switched in the direction of the palm side. In this posture, the camera unit 34, the speaker 32, and the wristwatch display unit 30 are turned off. Such automatic turning-off is automatically performed when the acceleration sensor provided in the wristwatch body 26 detects the posture change in FIGS. 2 (A) and 2 (B).

  FIG. 3 is another explanatory screen of the call posture displayed on the wristwatch display unit 30 in the first embodiment shown in FIG. . FIG. 3A shows a state in which the switch 44 shown in FIG. 1 is pressed with the right hand in the talking posture by the cartilage conduction shown in FIG. FIG. 3 (B) shows another talking posture by cartilage conduction. The thumb of the hand (for example, the left hand) in which the wristwatch type transmitter / receiver 4 is fitted is placed on the tragus of the ear (for example, the left ear) on the same side. It shows the posture applied to (ear cartilage). Even in this call posture, it is possible to convey to the other party his / her voice picked up by the microphone whose directivity is switched in the direction of the palm side.

  FIG. 4 is still another explanatory screen of the call posture displayed on the wristwatch display unit 30 in the first embodiment shown in FIG. FIG. 4 (A) shows a hand (for example, the left hand) in which the wristwatch type transmitter / receiver 4 is fitted in front of the face, and the index finger is applied to the tragus (the ear cartilage) of the opposite ear (for example, the right ear). It shows the call posture by the cartilage conduction. Further, FIG. 4B shows still another call posture by cartilage conduction. The bank portion of the lower part of the palm of the hand (for example, the left hand) in which the wristwatch type transmitter / receiver 4 is fitted is placed on the ear on the same side (for example, the left side). It shows the posture applied to the ear). In this case, the bank portion of the palm comes into extensive contact with the cartilage near the ear canal. If you press it hard, it will close your ears. 4A and 4B, the voice picked up by the microphone whose directivity is switched in the direction of the palm can be transmitted to the other party.

  5 is a block diagram of the first embodiment shown in FIG. 1. The same parts as those in FIG. 1 are denoted by the same reference numerals as those in FIG. 1, and the description thereof is omitted unless necessary. The mobile phone 2 is controlled by a control unit 60 that operates according to a program stored in the storage unit 58. The storage unit 58 can also temporarily store data necessary for the control of the control unit 60 and can store various measurement data and images. Display on the display unit 6 is performed based on display data held by the display driver under the control of the control unit 60. The display unit 6 has a display backlight, and the control unit 60 adjusts the brightness based on the ambient brightness. The display unit 6 includes a touch panel 6a, and the mobile phone 2 can be operated by touching the display unit.

The speaker 70 performs ringtones and various guidance under the control of the control unit 39 and outputs the other party's voice during a videophone call. The sound output from the speaker 60 is not output from the earphone 16. Further, the image processing unit 72 is controlled by the control unit 60 to process images picked up by the videophone inner camera 20 and the rear main camera 74, and inputs these processing result images to the storage unit 58.

  The mobile phone 2 includes a short-range communication unit 76 for communicating with the wristwatch-type transmitter / receiver 4 and an operation unit 78 such as a main switch for main power. The power supply unit 80 that supplies power to the entire mobile phone 2 includes a rechargeable battery that is supplied with power from the contactless charging unit 82.

  The wristwatch type transmitter / receiver 4 includes a short-range communication unit 77 for communicating with the mobile phone 2. It also has a clock function unit 84 for a normal clock function. The acceleration sensor 86 detects the rising of the wristwatch-type handset device 4 from (A) to (B) in FIG. 1 and the lowering of the wristwatch-type handset device 4 from (B) to (A) in FIG. The camera unit 34, the speaker 32, and the wristwatch display unit 30 are automatically switched.

  The power supply unit 88 of the wristwatch type transmitter / receiver 4 and the power supply unit 80 of the mobile phone 2 can be contactlessly charged by the contactless charging units 82 and 90, respectively, but share information on the state of charge of each other by short-range communication. In addition, cooperation between the wristwatch type transmitter / receiver 4 and the mobile phone 2 is ensured. Further, the GPS unit 92 detects the movement of the user wearing the wristwatch type transmitter / receiver 4 and checks whether the mobile phone 2 is not left in the original place each time. Cooperation between the receiver 4 and the mobile phone 2 is ensured. Specifically, it is checked whether or not the user moves out of the near field communication range.

  The drive unit 94 transmits the vibration for cartilage conduction from a wide area around the wrist by driving the main body cartilage conduction unit 36 and the belt cartilage conduction units 38 and 40 together. The sound processing unit 96 switches between vibration utterance for cartilage conduction by the driving unit 94 and air conduction sound generation by the speaker 32 according to an instruction from the control unit 98. The directional microphone 46 switches directivity according to an instruction from the control unit 98 via the audio processing unit. The audio processing unit 96 also switches whether the output signal from the driving unit is an audio signal with a frequency that causes a vibration sense cut or a vibration signal with a frequency range that causes a vibration sense that cuts an audible frequency range. The control unit 98 operates according to a program stored in the storage unit 98. The storage unit 98 can also temporarily store data necessary for the control of the control unit 98 and can also store various measurement data and images.

  Operation unit 100 includes buttons and the like for turning on the main power, calling operation, incoming call response operation, and the like. The wristwatch display unit 30 is a touch panel type as described above, has a touch panel 30a, displays the switch 44 and the like, and can operate the mobile phone 2 by touching the wristwatch display unit.

  FIG. 6 is a flowchart illustrating the function of the control unit 98 of the wristwatch type transmitter / receiver 4 according to the first embodiment. Note that the flow of FIG. 6 is illustrated by extracting the operation centering on the function related to cartilage conduction, and the wristwatch type transmitter / receiver 4 is not described in the flow of FIG. 6 including the normal wristwatch function. The operation of the control unit 4 exists. In FIG. 6, among the functions related to cartilage conduction, functions related to microphone directivity control, switching control between frequency range and sound frequency range causing vibration sensation, and belt portion tightening control are extracted. The other functions described in FIG. 5 are also omitted from illustration and description in order to avoid complications.

  The flow of FIG. 6 starts when the main power supply is turned on in the operation unit 100 of the wristwatch type transmitter / receiver 4, and at step S 2, initial startup and function check of each part are started, and normal clock display on the wristwatch display unit 30 is started. To do. Next, in step S4, the usage shown in FIGS. 2 to 4 is displayed in a slide show. When the usage explanation ends, the process proceeds to step S6.

  In step S6, when the cartilage conduction vibration source is driven, the audible frequency range is cut from the drive signal so as to vibrate around a frequency (for example, 20 Hz or less) that causes vibration sensation so that other people cannot hear the incoming vibration. Then, the circuit is switched so as to proceed to step S8. At this time, the cartilage conduction vibration source is not driven yet. When the process reaches step S6, if the audible frequency range is originally in the cut state, the process proceeds to step S8 without doing anything in step S6.

  In step S8, the vibration volume limiter is turned off and the process proceeds to step S10. The vibration sense volume limiter, as will be described later, when the cartilage conduction vibration source is vibrated in the audible frequency range, in order to prevent the vibration in the low frequency range that has not been cut completely from causing an unpleasant vibration sense, Is a limiter that prevents the signal from rising, and is provided in the audio processing unit. When the cartilage conduction vibration source is vibrated as an incoming vibrator, the purpose is to generate a vibration sensation. Therefore, such a vibration sensation volume limiter is turned off and the volume adjustment can be maximized. When step S8 is reached, if the vibration volume limiter is originally in the off state, nothing is done in step S6 and the process proceeds to step S8.

  In step S10, the operation unit 100 of the wristwatch type transmission / reception device 4 has been operated in response to the incoming signal transmitted from the mobile phone 2 by short-range communication, or the operation unit 100 of the wristwatch type transmission / reception device 4 operates. The calling operation is transmitted to the mobile phone 2 by short-range communication, and based on this, it is detected whether a response from the other party has been transmitted from the mobile phone 2 by short-range communication. When an incoming signal is transmitted, the cartilage conduction vibration source vibrates as an incoming vibrator, but at this time, the audible frequency range is cut based on the function of step S6 and vibrates. If there is either an incoming call response operation by the operation unit 100 or a response from the mobile phone 2 based on the outgoing call, it means that the mobile phone has started a call with the other party. move on.

  In step S12, the display of the other party's face on the wristwatch display unit 30, the imaging of his / her face by the camera unit, and the generation of air conduction sound by the speaker 32 are all turned on, and the directivity of the directional microphone 46 is set to the back side of the hand. After setting, the process proceeds to step S14. At this time, the cartilage conduction portion is turned off. Originally, when the display unit is on, the camera is on, the speaker is on, and the microphone directivity is on the back side of the hand, the process proceeds to step S14 without doing anything in step S12. Next, in step S14, the tightening state of the belt portion is made normal, and the process proceeds to step S18. When the tightening state of the belt portion is originally the normal tightening state and reaches step S14, nothing is performed in step S14, and the process proceeds to step S18. Thus, when starting a call, the videophone state is first set. The belt is normally tightened. If the call is not a videophone but only a voice, the display of the other party's face and the turning on of the camera unit are omitted.

  In step S16, it is checked whether or not the acceleration sensor 86 has detected the upward movement of the wristwatch type handset 4 from (A) to (B) of FIG. If there is a detection, the process proceeds to step S18, and the display of the other party's face on the wristwatch display unit, the imaging of his / her face by the camera unit, and the generation of air conduction sound by the speaker are all turned off and the cartilage conduction unit is turned on instead. Further, the directivity of the microphone is set to the palm side, and the process proceeds to step S18. Originally, when the display unit is off, the camera is off, the cartilage conduction unit is on, and the microphone directivity is on the palm side, the process proceeds to step S18 without doing anything in step S18.

  In step S20, the cartilage conduction vibration source vibrates the cartilage conduction in the frequency range of the audio signal (frequency centered at 1000 Hz) and generates a frequency (for example, 20 Hz or less) that causes vibration sense so that unpleasant vibration is not sensed by the wrist. Cut and move to step S22. When step S20 is reached, if the vibrational sensation wave number range is originally in the cut state, the process proceeds to step S22 without doing anything in step S20. In step S22, the vibration sensation prevention volume limiter described above is turned on, and the process proceeds to step S24. When step S22 is reached, if the vibration volume limiter is originally in the on state, the process proceeds to step S24 without doing anything in step S22.

  In step S24, it is checked whether or not the switch 44 is pressed. If it is pressed, the process proceeds to step S26, and the tightening force of the belt portion is increased, and the process proceeds to step S28. On the other hand, when it is detected that the switch 44 is not pressed, the process proceeds to step S30, the tightening force is returned to normal, and the process proceeds to step S28.

  In step S28, it is checked whether or not the wristwatch type transmitter / receiver 4 is lowered from (B) to (A) in FIG. 2 by the acceleration sensor 86. Return the setting to. On the other hand, if there is no downward detection in step S28 (normally this is the state as long as the cartilage conduction call is continued), the process proceeds to step S32 to check whether the call is disconnected. If the call is not disconnected, the process returns to step S16. Thereafter, until the call disconnection is detected in step S32, steps S12 to S32 are repeated to switch between the cartilage conduction call and the video phone corresponding to the change in posture. In addition, the tightening force is changed based on whether or not the switch is operated. On the other hand, when a call disconnection is detected in step S32, the process proceeds to step S36.

  In step S36, it is checked whether or not the main power supply of the wristwatch type transmitter / receiver 4 is turned off. If the main power supply is not turned off, the process returns to step S6, and thereafter, from step S6 unless the main power supply is detected in step S36. Step S36 is repeated. On the other hand, when the main power off is detected in step S36, the flow ends.

  FIG. 7 is a flowchart showing another function extracted from the function of the control unit 98 of the wristwatch type transmitter / receiver 4 according to the first embodiment. The flow of FIG. 7 also shows an extracted operation centering on the function related to cartilage conduction, and the wristwatch type transmitter / receiver 4 includes a control unit not shown in the flow of FIG. There are four actions. In FIG. 7, among other functions related to cartilage conduction, microphone directivity control and functions related to cooperation with the mobile phone 2 are extracted, and other functions described in FIGS. 1 to 5 and FIG. 6 are extracted. For the functions already described, illustration and description are omitted to avoid complications. Each function is separated into FIG. 6 and FIG. 7 for convenience of explanation, but in practice, the functions of FIG. 6 and FIG. 7 can be implemented collectively.

  The flow shown in FIG. 7 starts when the main power supply of the wristwatch type transmitter / receiver 4 is turned on, and at step S862, initial startup and each function check are performed, and normal clock display on the wristwatch display unit 30 is started. Next, in step S864, the usage shown in FIGS. 2 to 4 is displayed in a slide show. When the usage explanation ends, the process proceeds to step S866, and it is checked whether or not the movement of the user by the GPS unit has been detected.

  If there is no movement detection, the process proceeds to step S868, and it is checked whether or not a scheduled timing (for example, once every 5 seconds) for ensuring cooperation between the wristwatch-type transmitter / receiver 4 and the mobile phone 2 is checked. If applicable, the process proceeds to step S870. On the other hand, if a user movement by GPS is detected in step S866, the process directly proceeds to step S870. In step S870, it is checked whether or not the mobile phone is out of the short-range communication area. In step S872, short-distance communication with the mobile phone is performed, the power state of the wristwatch type handset 4 displayed on the wristwatch display unit is regularly checked, and the result is transmitted to the mobile phone 2. The transmitted information is displayed on the mobile phone. Further, in step S874, information indicating the power state of the mobile phone is received by short-range communication, the result is displayed on the wristwatch display unit, and the process proceeds to step S876. On the other hand, if it is not the scheduled timing in step S868, the process directly proceeds to step S876.

  In step S876, it is detected whether there is an incoming call to the mobile phone by short-range communication or whether there is a response from the other party based on the calling operation of the operation unit 6509 of the wristwatch type transmitter / receiver 4. If any of these is present, it means that a call with the other party via the mobile phone has been started, and the process proceeds to step S878, where the other party's face is displayed on the wristwatch display unit, his / her face is captured by the camera unit, and the speaker is used. The generation of air conduction sound is turned on and the directivity of the microphone is set on the back side of the wristwatch, and the process proceeds to step S880. At this time, the cartilage conduction portion is turned off. Thus, when starting a call, the videophone state is first set. If the call is not a videophone but only a voice, the display of the other party's face and the turning on of the camera unit are omitted.

  In step S880, it is checked whether or not the acceleration sensor 86 has detected the upward movement of the wristwatch type handset 4 from (A) to (B) of FIG. If detected, the process proceeds to step S882, where the display of the partner's face on the wristwatch display unit, the imaging of his / her face by the camera unit, and the generation of air conduction sound by the speaker are all turned off and the cartilage conduction unit is turned on instead. Further, the directivity of the microphone is set to the palm side, and the process proceeds to step S884.

  In step S884, it is checked whether or not the wristwatch type handset 4 has been lowered from (B) to (A) in FIG. 2 by the acceleration sensor 86. Return the setting to. On the other hand, if there is no downward detection in step S884 (it is normally in this state as long as the cartilage conduction call is continued), the process proceeds to step S886, and it is checked whether the call is disconnected. If the call is not disconnected, the process returns to step S880. Thereafter, until the call disconnection is detected in step S886, steps S878 to S886 are repeated to switch between the cartilage conduction call and the video phone corresponding to the change in posture. On the other hand, if a call disconnection is detected in step S886, the process proceeds to step S888. If no call start is detected in step S876, the process directly proceeds to step S888.

  In step S888, it is checked whether or not a mobile phone search operation by the operation unit 6509 has been performed. This operation is performed, for example, when the mobile phone is not found when going out. When the operation is performed, the process proceeds to step S890, where the mobile phone communicates with the mobile phone by short-range communication, transmits an instruction signal for generating a ringtone (or vibration of the vibrator) from the mobile phone, and proceeds to step S892. .

  On the other hand, when it is detected in step S870 that the mobile phone is out of the short-range communication range, the process proceeds to step S894, and a display for carrying that the mobile phone is in a non-portable state is performed, and the process proceeds to step S892. The cooperation between the wristwatch type transmitter / receiver 4 and the mobile phone 2 is ensured by various means as described above.

  In step S892, it is checked whether or not the main power supply of the wristwatch type transmitter / receiver 4 is turned off. If the main power supply is not turned off, the process returns to step S866, and thereafter, from step S866, unless the main power supply is detected in step S892. Step S892 is repeated. On the other hand, when the main power off is detected in step S892, the flow ends.

  The implementation of the various features shown in the first embodiment is not limited to the first embodiment, and other embodiments can be implemented as long as the advantages can be enjoyed. Further, as illustrated below, the various features shown in the first embodiment can be implemented with various modifications. These modifications can be carried out in combination as appropriate, and can also be carried out in combination with a state before partial deformation. ,

  For example, the vibration of the cartilage conduction vibration source is transmitted to the portion where the cartilage conduction vibration source is not provided through the conduction band 41 of the belt portion 28. Therefore, when the conduction efficiency of the conduction band 41 is good, the cartilage conduction vibration sources 38 and 40 Either of them may be omitted. Further, if the vibration of the cartilage conduction vibration source 36 of the wristwatch body 26 is transmitted to the conductor of the belt portion 28, the vibration can be transmitted from a wide area around the wrist even if both of the cartilage conduction vibration sources 38 and 40 are omitted. Can do. On the contrary, if the conductor 41 is extended to the back side portion of the wristwatch body 26 and the vibrations of either or both of the cartilage conduction vibration sources 38 and 40 are provided, the cartilage conduction vibration source can be obtained. It is also possible to omit 36. As described above, when the vibration for cartilage conduction is transmitted substantially over a wide range around the wrist, one or a few cartilage conduction vibration sources may be provided. Conversely, the number of cartilage conduction vibration sources may be increased as compared with the first embodiment to enhance the vibration transmission for cartilage conduction from a wide area around the wrist.

  Further, instead of employing the switch unit 44 displayed on the wristwatch display unit 30, a button having a similar function may be provided at a position corresponding to the cartilage conduction vibration source 38 or 40 in the belt unit 28. Even in this case, the operation of pressing the switch unit is the operation of bringing the cartilage conduction vibration source 38 or 40 into close contact with the wrist at the same time. The switching of the tightening force is not manually performed as described above, and the tightening force may be automatically increased when the rising acceleration is detected in step S16 in FIG. At this time, in order not to surprise the user, a short voice message “fasten the belt” may be input before turning off the speaker in step S18. Furthermore, for simplicity, the tightening mechanism may be omitted, and the cartilage conduction vibration source 38 or 40 may be brought into close contact with the wrist by simply pressing the switch portion. In this case, the function of the switch part can be used to turn on the vibration for sound transmission of the cartilage conduction part. Alternatively, the switch unit itself may be omitted, and the display unit of the wristwatch display unit 30 may be simply guided so as to press the vicinity of the position where the cartilage conduction vibration source is provided.

Furthermore, Example 1 is configured to transmit vibration from as wide a range as possible around the wrist,
Individual differences in suitable positions for vibration transmission, positional deviations during wearing of the wristwatch type transmitter / receiver 4 and the like are absorbed. On the other hand, as another embodiment, it is possible to measure highly effective vibration transmission points for each individual and concentrate the vibration at the optimum position. Even in this case, taking into account the shift in use, a slight spread is considered for the transmission range to be concentrated.

Furthermore, instead of the directivity variable microphone 46 in the first embodiment, it is possible to employ a wide-angle microphone that can pick up the sound on the back side of the hand and the sound from the palm side.
