The resonance unit 325 can transmit vibration from the vibrator 323a via the connection unit 313 in the storage form described later, and can resonate by the vibration to generate air conduction sound. The resonance part 325 of the present embodiment is a resonance box having a cavity at the center.

  In the usage pattern shown in FIG. 7, the vibrator 323a and the resonance unit 325 are not connected, and therefore the resonance unit 325 cannot resonate and no air conduction sound is generated. In this form of use, the vibration of the vibrator 323a is transmitted to the contact portion 323, so that the user can hear the sound using bone conduction by applying the contact portion 323 to the skull or the like. A first audio transmission mode can be used.

FIG. 8 is a cross-sectional view showing a storage configuration in which the mobile terminal device 300 is closed in the same manner as FIG.
When the storage mode is adopted, the connection portion 313 comes into contact with the contact portion 323, and the resonance portion 325 can resonate due to the vibration of the vibrator 323a and emit air conduction sound. In this storage mode, it is possible to use the second sound transmission mode in which the resonance unit 325 emits an air conduction sound according to the vibration of the vibrator 323a to transmit the sound to the user.

  As described above, according to the third embodiment, by providing the connection unit 313 as a switching unit, the first sound transmission mode (using air conduction sound) and the second sound transmission mode (using bone conduction). ). Therefore, the first sound transmission mode that generates air conduction sound by simply rotating the first housing 310 and the second housing 320 and opening and closing them without performing an operation for switching. And the second voice transmission mode in which the voice is transmitted by transmitting the vibration to the human body can be automatically switched. Further, since these two sound transmission methods are selectively used using only one vibrator 323a, the apparatus can be reduced in size and weight. Furthermore, since the configuration is simpler than that of the first embodiment, the device can be further reduced in size and weight.

(Fourth embodiment)
FIG. 9 is a block diagram illustrating a mobile terminal device 400 according to the fourth embodiment.
In the portable terminal device 400 of the fourth embodiment, at least a part of the housing is used and accommodated with respect to the other housing parts in the same manner as the portable terminal devices of the first to third embodiments described above. The movable part 430 which moves relatively between forms is provided. The specific form of the movable part may be any of the folding type shown in the first embodiment and the third embodiment or the slide type shown in the second embodiment. The detailed description of is omitted.

  The mobile terminal device 400 according to the fourth embodiment includes a control unit 410, a resonance unit 425, a first vibrator 425a, a contact unit 423, a second vibrator 423a, a movable unit 430, and an open / close detection unit. 440.

  The control unit 410 is a part that performs various controls of the mobile terminal device 400. The control unit 410 includes an audio control unit 411 and a switching unit 412.

  The voice control unit 411 controls the voice at the time of the call, the ringtone at the time of the incoming call (including the incoming melody, etc.), and the voice transmitted from the portable terminal device 400 to the user.

  The switching unit 412 transmits a voice to be transmitted to the user by the voice control unit 411 using a first vibrator 425a described later according to the detection result of the open / close detection unit 440 (first voice transmission mode). Or switching means for switching between transmission using the second vibrator 423a (second audio transmission mode). That is, when the detection result of the open / close detection unit 440 is in the usage pattern, the switching unit 412 switches to use the second audio transmission mode. On the other hand, when the detection result of the open / close detection unit 440 is in the storage form, the switching unit 412 switches to use the first audio transmission mode.

  The switching unit 412 switches between the first audio transmission mode and the second audio transmission mode according to the audio processed by the audio control unit 411. For example, even if the switching unit 412 has switched to the second voice transmission mode based on the detection result of the open / close detection unit 440, if there is an incoming call from the outside, the switching unit 412 switches to the first voice transmission mode and receives the incoming call. We convey by air conduction sound. Thereby, for example, even when the portable terminal device 400 is placed on a desk or the like in a usage pattern, an incoming call can be notified by air conduction sound.

  The resonance unit 425 is connected so that one surface is integrated with the first vibrator 425 a, and the other surface is disposed toward the outside of the mobile terminal device 400. The resonance unit 425 can receive vibration from the first vibrator 425a and can resonate by the vibration to generate air conduction sound. The resonance part 425 of the present embodiment is a resonance box having a cavity at the center.

  The first vibrator 425a is driven and controlled by the control unit 410 and vibrates according to the audio signal. Further, as the first vibrator 425a, for example, a bimorph vibrator in which piezoelectric elements are stacked can be used.

  The contact portion 423 is a portion used when transmitting sound using bone conduction, and vibrates when the vibration of the second vibrator 423a is transmitted. The contact portion 423 transmits vibration to the user's skull or the like by being brought into contact with the user's head or the like.

  The second vibrator 423a is driven and controlled by the control unit 410 and vibrates in accordance with the audio signal. In addition, as the second vibrator 423a, for example, a bimorph vibrator in which piezoelectric elements are stacked can be used.

  The movable portion 430 is at least a part of the housing, and moves relative to the other housing portions between the storage mode and the usage mode. For example, the folding type shown in the first embodiment and the third embodiment may be used, or any of the sliding types shown in the second embodiment may be used. Moreover, the movable part of other forms other than having shown in 1st Embodiment to 3rd Embodiment may be sufficient.

  The open / close detection unit 440 detects whether the movable unit 430 is moved to be in the storage form (closed state) or in the use form (open state). For example, in the case of a folding type, the open / close detection unit 440 can be configured by a switch provided in the shaft portion.

  As described above, according to the fourth embodiment, the control unit 410 includes the switching unit 412, so that the first sound transmission mode (using air conduction sound) and the second sound transmission mode (bone conduction can be performed). Use). Therefore, the mobile terminal device 400 can switch between the first audio transmission mode and the second audio transmission mode without requiring a physical operation. Therefore, the voice transmission mode can be switched more finely according to the situation, such as automatically switching to the first voice transmission mode when receiving an incoming call.
