Description

  The present invention relates to a mobile terminal device such as a mobile phone, a PDA (Personal Digital Assistant), a tablet PC (Tablet PC), and an electronic book terminal, and more particularly to a mobile terminal device having a call function. The present invention also relates to a program and a sound output control method suitable for use in such a portable terminal device.

  Conventionally, in a mobile phone, a speaker and a microphone for calling are arranged on one surface of the device main body. During a call, the user puts his ear close to the speaker for call and listens to the received voice from the other party.

  In such a cellular phone, in order to provide a clear sound to the user, it may be considered to employ a so-called cartilage conduction type speaker as a speaker for calling (see Patent Document 1).

  The cartilage conduction type speaker includes a diaphragm such as a piezoelectric vibration element, and vibrates one surface of the device main body with the diaphragm. When the user contacts the ear with one surface of the device main body, the auricular cartilage vibrates due to the vibration of the entire surface, and the vibration of the auricular cartilage is transmitted to the eardrum to vibrate the eardrum. Thereby, a sound is recognized in a user's brain.

JP 2005-348193 A

  In a cartilage conduction type speaker, a sound wave is generated by vibration of one surface of the device body, and the user can also recognize the sound by transmitting the sound wave to the eardrum. However, the sound pressure of the generated sound wave is small.

  In the case where the structure is provided with a cartilage conduction type speaker, the user can hear a clear sound if the ear is in contact with the device main body. However, it is not easy for the user to keep his / her ear in contact with the device body during a call without being conscious of it. When the ear is separated from the device body, the transmission of sound through the auricular cartilage is cut off. Sound is transmitted by sound waves, but since the sound pressure is small, it is difficult for the user to hear the sound.

  Depending on the sound information obtained during a call, it may be less desirable that the sound is interrupted due to the ear being removed from the device body.

  Therefore, an object of the present invention is to provide a mobile terminal device, a program, and a sound output control method by which a user can obtain sound information satisfactorily.

  A portable terminal device according to a first aspect of the present invention includes a housing, a call speaker that can output a received voice during a call, and a control unit that controls the output of the call speaker. The call speaker includes a first speaker that transmits a received voice using a vibration wave generated by vibration of one surface of the housing, and a second speaker that transmits the received voice using a sound wave. When the call is started, the control unit can execute the first control that outputs the received voice from the first speaker and does not output the received voice from the second speaker, and when a predetermined notification sound is generated, Second control for outputting a notification sound from the second speaker is executed.

  In the mobile terminal device according to this aspect, the second speaker may be configured not to use vibration generated by vibration of one surface of the casing.

  In the mobile terminal device according to this aspect, the predetermined notification sound may be an alert sound that is output when an incoming call is received.

  In the mobile terminal device according to this aspect, the predetermined notification sound may be an alarm sound output at a time set by a user.

  A program according to a second aspect of the present invention includes a first speaker that transmits a received voice using a vibration wave generated by vibration of one surface of a housing, and a second speaker that transmits a received voice using a sound wave. When a computer of a mobile terminal device starts a call and executes a first control that outputs a reception voice from the first speaker and does not output a reception voice from the second speaker, and a predetermined notification sound is generated Then, the second control for outputting the notification sound from the second speaker is executed.

  According to a third aspect of the present invention, there is provided a portable terminal device including a first speaker that transmits a received voice using a vibration wave generated by vibration of one surface of a housing, and a second speaker that transmits the received voice using a sound wave. The present invention relates to a sound output control method. In the sound output control method according to this aspect, when a call is started, a first control is performed in which a reception voice is output from the first speaker and a reception voice is not output from the second speaker. When it occurs, the second control for outputting a notification sound from the second speaker is executed.

  ADVANTAGE OF THE INVENTION According to this invention, the user can provide the portable terminal device which can obtain sound information favorably, a program, and a sound output control method.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<First Embodiment>
FIG. 1 is a diagram showing a configuration of the mobile phone 1. 1A and 1B are a front view and a rear view, respectively. FIG.1 (c) is a fragmentary sectional view of the cabinet 2 which shows the structure of the telephone call speaker part SP.

  Hereinafter, for convenience of explanation, as shown in FIG. 1, the longitudinal direction of the cabinet 2 is defined as the up-down direction, and the short direction of the cabinet 2 is defined as the left-right direction.

  The mobile phone 1 includes a cabinet 2, a display surface 3, a microphone 4, a call speaker unit SP (first call speaker 5 and second call speaker 6), a key operation unit 7, and an external speaker 8. Yes.

  The cabinet 2 has a substantially rectangular shape when viewed from the front. A display surface 3 of a display unit to be described later is arranged on the front surface 2 a of the cabinet 2. That is, the front surface 2 a of the cabinet 2 includes a display surface 3 and a frame portion surrounding the display surface 3. Various images (screens) are displayed on the display surface 3.

  Inside the cabinet 2, a microphone 4 is disposed at the lower end, and a call speaker SP is disposed at the upper end. The call speaker unit SP includes a first call speaker 5 and a second call speaker 6, and mainly outputs a received voice from a call partner during a call.

  A microphone hole 4 a is provided on the front surface 2 a of the cabinet 2 at a position corresponding to the microphone 4. The microphone 4 receives the sound taken in from the microphone hole 4a. The microphone 4 generates an electrical signal corresponding to the input sound.

  As shown in FIG. 1 (c), the first call speaker 5 is a so-called cartilage conduction type speaker, and includes, for example, a piezoelectric vibration element 50. The piezoelectric vibration element 50 has a bimorph structure, and includes a shim material 50a, and first and second piezoelectric ceramic plates 50b and 50c mounted on both sides of the shim material 50a.

  The piezoelectric ceramic plates 50b and 50c are respectively applied with AC voltages having a positive voltage and a negative voltage and having phases opposite to each other. By applying an AC voltage, the operation of extending the first piezoelectric ceramic plate 50b and contracting the second piezoelectric ceramic plate 50c and the operation of contracting the first piezoelectric ceramic plate 50b and extending the second piezoelectric ceramic plate 50c are repeated. 50 vibrates.

  The piezoelectric vibration element 50 is attached to the inner surface of the front surface 2 a of the cabinet 2 with an adhesive 51.

  The piezoelectric vibration element 50 vibrates based on an electrical signal corresponding to sound. When the piezoelectric vibration element 50 vibrates, vibration corresponding to the sound is transmitted to the front surface 2a of the cabinet 2, and the front surface 2a vibrates. When the user's ear is directed to the front surface 2a of the cabinet 2, that is, when the ear is brought close to or in contact with the front surface 2a, sound waves generated by vibration of the cabinet 2 enter the ear canal from the ear canal hole. The sound waves that have entered enter the ear canal and vibrate the eardrum. Thereby, the voice is recognized in the user's brain. Furthermore, when the user's ear contacts the front surface 2a of the cabinet 2, the auricular cartilage is vibrated by the vibration of the cabinet 2, and the vibration of the auricular cartilage is transmitted to the eardrum to vibrate the eardrum.

The sound, that is, the sound wave output from the second call speaker 6 is emitted to the outside through the sound output port 6a. When the user's ear is directed to the front surface 2a of the cabinet 2, the sound wave emitted from the sound outlet 6a enters the ear canal through the ear canal hole and vibrates the eardrum. Thereby, the voice is recognized in the user's brain.

  As described above, in the first call speaker 5 (piezoelectric vibration element 50), sound waves are generated when the cabinet 2 vibrates, so that even if the ear is away from the cabinet 2, the user can hear the sound. However, the sound pressure due to the vibration of the cabinet 2 has a lower sound pressure than the sound wave output from the second call speaker 6. Therefore, the sound that reaches the user's ear can be much smaller than the sound from the second call speaker 6.

  That is, the sound from the first call speaker 5 is less likely to leak to the surroundings than the sound from the second call speaker 6, but the sound is heard compared to the second call speaker 6 when the user removes his ear from the cabinet 2. It becomes difficult. On the other hand, the sound from the second call speaker 6 is more likely to leak to the surroundings than the sound from the first call speaker 5, but the sound is higher than the sound from the first call speaker 5 even when the user is away from the cabinet 2. Becomes easier to hear.

  A key operation unit 7 is provided on the front surface 2 a of the cabinet 2. The key operation unit 7 is composed of a plurality of operation keys. Each operation key is assigned various functions according to the program being executed.

  An external speaker 8 is disposed inside the cabinet 2. The external speaker 8 is an air-conducting speaker, similar to the second call speaker 6. A sound output port 8 a corresponding to the external speaker 8 is formed on the back surface 2 b of the cabinet 2. The sound output port 8a is formed by a plurality of holes. Sound (sound, notification sound, etc.) output from the external speaker 8, that is, sound waves, is emitted to the outside through the sound output port 8a.

  In this modification, the processes of steps S111 and S112 are added to the notification sound output process of the first embodiment. Hereinafter, the added process will be described.

  The control unit 11 determines whether or not a predetermined notification sound is being output during a call (S111). If the predetermined notification sound is not output (S111: NO), the control unit 11 outputs the received voice from the first call speaker 5 (S102).

  When the output of a predetermined notification sound is started from the first call speaker 5 (S111: YES), the control unit 11 causes the second call speaker 6 to output the received voice (S112). The second call speaker 6 outputs a predetermined notification sound and received voice. When the output of the predetermined notification sound is completed (S111: NO), the control unit 11 again outputs the received voice from the first call speaker 5 (S102).

<Modification 2 of the first embodiment>
FIG. 5 is a flowchart showing a flow of notification sound output processing according to the second modification.

  In the present modification, steps S211 to S214 are added to the notification sound output processing of the first embodiment. Hereinafter, the added process will be described.

  When the output timing of the predetermined notification sound is during a call (S202: YES), the control unit 11 switches the output destination of the predetermined notification sound from the second call speaker 6 to the first call speaker 5 (the present invention). (Corresponding to the switching operation from the second control to the first control) is determined (S211). For example, one operation key of the key operation unit 7 is assigned to the switching operation.

  As described above, the sound from the second call speaker 6 is more likely to leak to the surroundings than the sound from the first call speaker 5. For example, the user performs a switching operation when it is desired to suppress leakage of the notification sound to the surroundings.

  When determining that the switching operation has been performed (S211: YES), the control unit 11 outputs a notification sound from the first call speaker 5 (S212).

  The control unit 11 determines whether or not an operation for returning the output destination of the predetermined notification sound from the first call speaker 5 to the second call speaker 6 has been performed while the timing for ending the output of the notification sound has not arrived (S213: NO). Is determined (S214). For example, one operation key of the key operation unit 7 is assigned to the return operation. The operation key assigned to the return operation may be the same as or different from the operation key assigned to the switching operation.

  When determining that the return operation has been performed (S214: YES), the control unit 11 causes the second call speaker 6 to output a notification sound (S203).

  As described above, according to this modified example, the user can switch the output destination of the notification sound from the second call speaker 6 to the first call speaker 5 according to the surrounding situation. Therefore, the convenience of the mobile phone 1 for the user is improved.

Second Embodiment
In the present embodiment, the received voice is output from the second call speaker 6 during a call with a predetermined call destination.

  The storage unit 12 stores information indicating a predetermined call destination, for example, a telephone number. The predetermined call destination is stored in advance in the storage unit 12 when the user performs a registration operation using a predetermined setting screen. The user registers, for example, a call partner who wants to avoid interruption of the received voice as a predetermined call destination, such as a business partner.

  FIG. 6 is a flowchart showing the flow of received voice output processing. The configuration other than the configuration related to the received voice output processing is the same as that of the first embodiment.

  When the call is started (S301: YES), the control unit 11 compares the telephone number of the current call destination with the telephone number stored in the storage unit 12, for example. It is determined whether or not the call destination is (S302).

  If it is not a predetermined call destination (S302: NO), the control part 11 will output a receiving voice from the 1st call speaker 5 (S303). The control unit 11 does not output the received voice from the second call speaker 6. When the call ends (S304: YES), the control unit 11 ends the received voice output process.

  On the other hand, when it determines with it being a predetermined call destination (S302: YES), the control part 11 outputs a receiving voice from the 2nd call speaker 6 (S305). The control unit 11 does not output the received voice from the first call speaker 5. When the call ends (S306: YES), the control unit 11 ends the received voice output process.

  As described above, according to the present embodiment, since the received voice from other than the predetermined call destination is output from the first call speaker 5, the user keeps the ear in contact with the cabinet 2, so that ambient noise or the like can be obtained. You can hear clear incoming voice without being greatly affected. Furthermore, leakage of received voice to the surroundings can be suppressed.

  Furthermore, according to the present embodiment, since the received voice from the predetermined call destination to avoid overhearing is output from the second call speaker 6, even if the ear is away from the cabinet 2, the user can perform the predetermined call. You can hear the incoming call from the destination.

<Modification Example of Second Embodiment>
FIG. 7 is a flowchart showing a flow of received voice output processing according to the modified example.

  In this modified example, the processes of steps S311 to S313 are added to the received voice output process of the first embodiment. Hereinafter, the added process will be described.

  The control unit 11 switches the output destination of the received voice from the second call speaker 6 to the first call speaker 5 while outputting the received voice from the predetermined call destination from the second call speaker 6 (the present invention). It is determined whether or not a switching operation from the second control to the first control has been performed (S311). For example, one operation key of the key operation unit 7 is assigned to the switching operation.

  For example, the user performs a switching operation when the ambient noise is large or when it is desired to suppress leakage of the notification sound to the surroundings.

  When the control unit 11 determines that the switching operation has been performed (S311: YES), the control unit 11 outputs the received voice from the first call speaker 5 (S303).

  When the output destination is switched from the second call speaker 6 to the first call speaker 5 during a call (S312: YES), the control unit 11 changes the output destination of the received voice from the first call speaker 5 to the second call. It is determined whether or not an operation for returning to the speaker 6 has been performed (S313). For example, one operation key of the key operation unit 7 is assigned to the return operation.

  When determining that the return operation has been performed (S313: YES), the control unit 11 causes the second call speaker 6 to output the received voice (S305).

  As described above, according to this modified example, the user can switch the output destination of the received voice from the second call speaker 6 to the first call speaker 5 according to the surrounding situation. Therefore, the convenience of the mobile phone 1 for the user is improved.

  FIG. 8 is a flowchart showing the flow of received voice output processing. The configuration other than the configuration related to the received voice output processing is the same as that of the first embodiment.

  When the call is started (S401: YES), the control unit 11 switches the reception destination of the received voice from the first call speaker 5 to the second call speaker 6 (from the first control of the present invention to the second control). It is determined whether or not a corresponding switching operation has been performed (S402). For example, one operation key of the key operation unit 7 is assigned to the switching operation.

  If there is no switching operation (S402: NO), the control part 11 will output a receiving voice from the 1st call speaker 5 (S403). The control unit 11 does not output the received voice from the second call speaker 6. When the call ends (S404: YES), the control unit 11 ends the received voice output process.

  The control unit 11 continues to monitor the switching operation until the call is terminated (S402).

  For example, the switching operation is performed by the user when the user is easily walking away or the user is shaking on the train or the like, and the earphone is easily removed from the cabinet 2 and the received voice is easily missed. A case is assumed. Alternatively, it is assumed that the switching operation is performed by the user when the content of the call is important and the talk should not be overlooked.

  When the switching operation is performed (S402: YES), the control unit 11 outputs the received voice from the second call speaker 6 (S405). The control unit 11 does not output the received voice from the first call speaker 5. When the call ends (S406: YES), the control unit 11 ends the received voice output process.

  The control unit 11 determines whether or not a return operation has been performed until the call is terminated (S407). For example, one operation key of the key operation unit 7 is assigned to the return operation.

  When the control unit 11 determines that the return operation has been performed (S407: YES), the control unit 11 outputs the received voice from the first call speaker 5 again (S403).

Furthermore, leakage of received voice to the surroundings can be suppressed.

  Furthermore, according to the present embodiment, since the received voice is output from the second call speaker 6 by performing the switching operation, the user sufficiently listens to the received voice even when the ear is away from the cabinet 2. be able to.

<Fourth embodiment>
In the present embodiment, when the ear of the user who has been in contact with the cabinet 2 is away from the cabinet 2 during a call, the received voice is output from the second call speaker 6.

  FIG. 9A is a diagram (front view) illustrating the configuration of the mobile phone 1. FIG. 9B is a flowchart showing the flow of received voice output processing.

  In the present embodiment, a proximity sensor 9 is disposed at the upper end of the cabinet 2. The sensitivity of the proximity sensor 9 is adjusted so that a detection signal is output to the control unit 11 when the user's ear touches a region near the proximity sensor 9 on the front surface 2 a of the cabinet 2. The proximity sensor 9 may be disposed at any position in the cabinet 2 as long as it can detect the presence or absence of ear contact with the front surface 2 a of the cabinet 2.

  When receiving the detection signal from the proximity sensor 9, the control unit 11 determines that the ear is in contact with the cabinet 2, and determines that the ear is separated from the cabinet 2 when the detection signal disappears.

  The configuration other than the configuration related to the received voice output processing is the same as that of the first embodiment.

  The received voice output process will be described with reference to FIG.

  When the call is started (S501: YES), the control unit 11 determines whether or not the user's ear has been removed from the cabinet 2 (S502). This determination is started after it is detected that the ear has first contacted after the call is started.

  If the ear is in contact with the cabinet 2 (S502: NO), the control unit 11 outputs the received voice from the first call speaker 5 (S503). The control unit 11 does not output the received voice from the second call speaker 6. When the call ends (S504: YES), the control unit 11 ends the received voice output process.

  The control unit 11 continues to monitor whether or not the user's ear has left the cabinet 2 until the call is terminated (S502).

  When the control unit 11 detects that the ear is separated from the cabinet 2 (S502: YES), the control unit 11 outputs the received voice from the second call speaker 6 (S505). The control unit 11 does not output the received voice from the first call speaker 5. When the call ends (S506: YES), the control unit 11 ends the received voice output process.

  The control unit 11 determines whether or not the ear has touched the cabinet 2 until the call is terminated (S507).

  When the control unit 11 determines that the ear has contacted the cabinet 2 (S507: YES), the control unit 11 outputs the received voice from the first call speaker 5 again (S503).

  As described above, according to the present embodiment, if the user's ear is in contact with the cabinet 2, the received voice is output from the first call speaker 5, so that the user is not greatly affected by ambient noise or the like. Can hear clear incoming voice. Furthermore, leakage of received voice to the surroundings can be suppressed.

  Furthermore, according to the present embodiment, if the user's ear is away from the cabinet 2, the received voice is output from the second call speaker 6. Therefore, even if the ear is away from the cabinet 2, the user can sufficiently receive the received voice. Can listen to.

<Others>
Although the embodiment and modification examples of the present invention have been described above, the present invention is not limited to the above embodiment and the like, and various modifications other than the above can be made in the embodiment of the present invention. is there.

  For example, in the first embodiment, an external speaker 8 is provided. However, as shown in FIG. 10, the second speaker 10 having a wide volume range is used for the speaker unit SP, and the second speaker 10 is also used as an external speaker, so that the external speaker 8 is eliminated. May be. In this case, the notification sound output process shown in FIG. 11 is executed. When outputting a predetermined notification sound during a call, the control unit 11 outputs a notification sound from the second call speaker 10 at a low volume through the sound output port 10a (S221). When outputting the notification sound, the notification sound is output from the second call speaker 10 at a high volume through the sound output port 10a (S222).

  Furthermore, in the modified example 2 of the first embodiment, the modified example of the second embodiment, and the third embodiment, the operation keys of the key operation unit 7 are assigned to the switching operation and the return operation. However, the present invention is not limited thereto, and the control unit 11 may display soft keys assigned to the switching operation and the return operation on the display surface 3.

  Furthermore, the first to fourth embodiments can be combined as appropriate.

  Further, in the fourth embodiment, the proximity sensor 9 detects whether the ear is in contact with the cabinet 2. However, the present invention is not limited to this. For example, the touch panel of the touch detection unit 14 may be used to detect whether or not the ear is in contact. In this case, during a call, a touch operation on the display surface 3 is prohibited, and an operation related to the call is performed by the key operation unit 7.
