JP 2007-52785 A

  In a mobile terminal, it is generally performed to notify the user by vibration when receiving a voice call or receiving an e-mail. The degree of vibration when receiving a voice call or receiving an e-mail is often set to be stronger for that purpose. Under such circumstances, the present inventor has recognized the following problems. When a touch panel is mounted on a mobile terminal having a communication function, if the same vibration mode is used for touching the touch panel and receiving a call, there is a disadvantage that the touch screen cannot be touched accurately due to strong shaking of the screen during operation.

  In the following, the same or equivalent components, members, and signals shown in each drawing will be denoted by the same reference numerals, and repeated description will be omitted as appropriate. In addition, the dimensions of the members in each drawing are appropriately enlarged or reduced for easy understanding. In the drawings, some of the members that are not important for describing the embodiment of the present invention are omitted.

A mobile terminal device according to an embodiment is a mobile terminal such as a mobile phone or a PDA, and receives input from a user through a touch panel and has a communication function. Here, as communication, e-mail transmission / reception, voice call, web access, and the like are executed, but here, for the sake of clarity, the description will focus on incoming e-mail.
The portable terminal device according to the embodiment includes a vibration motor that generates vibration, and vibrates in response to an input operation such as a touch panel operation or an incoming call. The vibration motor is shared between the strong vibration mode corresponding to the incoming call and the weak vibration mode corresponding to the touch panel operation.

  FIG. 1 is a perspective view showing a mobile terminal device 100 according to an embodiment. The mobile terminal device 100 includes a display unit 102, a power switch 104, an antenna 106, a housing 108, and a vibration motor 110. Other configurations are omitted in FIG. 1 for the sake of clarity. The user turns on the power switch 104 to turn on the mobile terminal device 100. The display unit 102 includes a liquid crystal panel and a touch panel 116 (hereinafter collectively referred to as a touch panel 116) covering the liquid crystal panel. The user operates the mobile terminal device 100 by pressing down a portion corresponding to a button or the like displayed on the touch panel 116. The touch panel 116 accepts such a touch from the user, and the mobile terminal device 100 executes a software program in response to the touch from the user. The antenna 106 transmits and receives radio signals.

  The vibration motor 110 is fixed to the housing 108, and when the mobile terminal device 100 receives a call or when the user touches the touch panel 116, the vibration motor 110 vibrates to vibrate the housing 108. . This vibration allows the user to feel that one input operation among a plurality of types of input operations such as an incoming e-mail and a touch on the touch panel 116 has been performed.

  FIG. 2 is a functional block diagram of the mobile terminal device 100. Each block shown here can be realized in hardware by an element such as an integrated circuit or a mechanical device, and in software it is realized by a computer program or the like, but here it is realized by their cooperation. Draw functional blocks. Therefore, those skilled in the art will understand that these functional blocks can be realized in various forms by a combination of hardware and software.

The mobile terminal device 100 includes a reception unit 112, a control unit 114, a touch panel 116, a touch input unit 117, a communication unit 118 connected to the antenna 106, a processing unit 150, a display control unit 152, and a vibration motor. 110.
The reception unit 112 includes an incoming call detection unit 119 and a touch detection unit 120, and receives an input operation due to an incoming call to the mobile terminal device 100 or an input operation due to a user touching the touch panel 116.

The control unit 114 includes an incoming call control unit 122, a vibration period setting unit 124, a voltage generation unit 126, a first switch 128, a vibration control unit 130, and a second switch 132. When the reception unit 112 receives a touch on the touch panel 116 by the reception unit 112, the control unit 114 selects the touch panel operation vibration mode. When an incoming e-mail is accepted, the incoming vibration mode is selected. When the touch panel operation vibration mode is selected, the control unit 114 causes the vibration motor 110 to vibrate with a drive voltage having the first frequency f ₁ . The control unit 114, when selecting the incoming vibration mode, allowed to vibrate the vibration motor 110 by a drive voltage having a second frequency f _2.

  Hereinafter, a case where the touch panel 116 is touched will be described, a case where an incoming e-mail is received will be described, and a case where another process is executed next will be described.

  The touch input unit 117 receives a touch on the touch panel 116 by the user, and outputs it to the touch sensing unit 120 as an electrical signal. This is accomplished by known means. The touch sensing unit 120 receives an electrical signal corresponding to the user's touch from the touch input unit 117. Then, the touch sensing unit 120 outputs a touch sensing signal S1 for generating one pulse for one touch sensing to the vibration period setting unit 124.

The vibration period setting unit 124 detects a pulse appearing in the touch detection signal S1 or an incoming vibration start signal S8 described later, and outputs a second control signal S2 to the second switch 132 to control on / off of the second switch 132. In a state where no pulse is detected in either the touch detection signal S1 or the incoming vibration start signal S8, the second control signal S2 is at a low level. When the vibration period setting unit 124 detects a pulse in the touch detection signal S1, the vibration period setting unit 124 sets the second control signal S2 to a high level during a predetermined touch vibration period T1.
The touch vibration period T1 is set in a range necessary for the user to sense vibration.

  The voltage generator 126 generates a constant first voltage V1 corresponding to the touch panel operation vibration mode and a constant second voltage V2 corresponding to the incoming vibration mode. The voltage generator 126 applies the first voltage V <b> 1 to the first terminal 134 of the first switch 128. Further, the second voltage V <b> 2 is applied to the second terminal 136 of the first switch 128.

  The first switch 128 has a first terminal 134, a second terminal 136, and a third terminal 138. The first voltage V1 is applied to the first terminal 134 by the voltage generator 126, and the second voltage V2 is applied to the second terminal 136. The third terminal 138 is connected to the vibration control unit 130. The first switch 128 connects the first terminal 134 and the third terminal 138 when a later-described first control signal S7 is at a low level, and connects the second terminal 136 and the second terminal 136 when the first control signal S7 is at a high level. 3 terminals 138 are connected. Accordingly, when the touch panel 116 is operated, details will be described later. However, as long as there is no incoming e-mail, the third terminal 138 is connected to the first terminal 134, so the vibration controller 130 is supplied with the first voltage V1. .

The vibration controller 130 is connected to the third terminal 138 of the first switch 128 and receives the mode voltage signal S3 appearing there. Then, the original drive voltage S4 is supplied to the second switch 132. From the above description, the mode voltage signal S3 becomes the first voltage V1 or the second voltage V2. The vibration control unit 130 changes the frequency of the original drive voltage S4 according to each voltage value. That is, when the mode voltage signal S3 is the first voltage V1, the frequency of the original drive voltage S4 to the first frequency f _1, when the mode voltage signal S3 is the second voltage V2, the frequency of the original drive voltage S4 the a second frequency _{f 2.} The reason will be described later, but f ₁ <f ₂ is set. The amplitude of the original drive voltage S4 is kept constant.

  The second switch 132 is a switch for supplying the original drive voltage S4 supplied from the vibration control unit 130 to the vibration motor 110 described later. When the second control signal S2 is at a low level, it is turned off. When the second control signal S2 is at a high level, it is turned on, and the drive voltage S5 is supplied to the input terminal 16 of the vibration motor 110.

  Next, a case where there is an incoming e-mail will be described. The communication unit 118 transmits and receives wireless signals via the antenna 106 and communicates with an external wireless device (not shown). Here, the communication unit 118 corresponds to a wireless LAN (Local Area Network) system or a mobile phone system. However, since a known technique may be used for them, description thereof will be omitted. When the communication unit 118 receives an incoming e-mail notification from an external wireless device (not shown), the communication unit 118 outputs an electrical signal notifying the incoming call detection unit 119 that the e-mail has arrived. Upon receiving the electrical signal, the incoming call sensing unit 119 outputs an incoming signal S6 that is at a high level for a certain period T4 after receiving the incoming call to the incoming call control unit 122 and the vibration period setting unit 124. To do.

The incoming call control unit 122 receives the incoming signal S6 from the incoming call detection unit 119, and outputs the first control signal S7 to the first switch 128 to control the connection. When the incoming signal S6 is at a low level, that is, when there is no incoming email, the first control signal S7 is at a low level. When an incoming e-mail is received and the incoming signal S6 becomes high level, the first control signal S7 also becomes high level. Then, while the incoming signal S6 is at a high level, that is, for a certain period after the incoming call is received, the first control signal S7 is also at a high level.
Further, the incoming call control unit 122 outputs to the vibration period setting unit 124 an incoming vibration start signal S8 in which a pulse is generated after a predetermined delay time τ has elapsed from the rising edge when the incoming signal S6 becomes high level. To do.
The predetermined delay time τ is determined in consideration of the processing time in the first switch 128 and the vibration control unit 130.

Regarding the vibration period setting unit 124, when the incoming signal S6 becomes a high level and the vibration period setting unit 124 detects a pulse in the incoming vibration start signal S8, the vibration period setting unit 124 detects the second control signal S2 at a predetermined incoming vibration period T3. Is set to a high level during a predetermined incoming vibration period T2. Here, naturally, T4>T3> T2. When the incoming signal S6 becomes low level after a certain period T4 after receiving the incoming call, the operation of periodically setting the second control signal S2 to high level is terminated.
When pulses are detected almost simultaneously in the touch detection signal S1 and the incoming vibration start signal S8, the vibration period setting unit 124 prioritizes processing when a pulse is detected in the touch detection signal S1.
The incoming vibration period T2 and the incoming vibration period T3 are selected so that the user can detect incoming calls by vibration.

  The operations of the voltage generation unit 126, the first switch 128, the vibration control unit 130, and the second switch 132 when an e-mail is received are as described when the touch panel 116 is touched. In the first switch 128, since the second terminal 136 and the third terminal 138 are connected while the first control signal S7 is at the high level, the mode voltage signal S3 is changed from the first voltage V1 to the second voltage V2 during that time. Switch to

The vibration motor 110 is vibrated by the drive voltage S5 input to the input end 16 thereof. Description will be described later, the degree of vibration when the frequency of the drive voltage S5 is the second frequency f ₂ is larger than the degree of oscillation when the frequency is the first frequency f _1. Therefore, the degree of vibration at the time of incoming e-mail is greater than the degree of vibration at the time of touch panel operation. The degree of vibration is, for example, the intensity of vibration experienced by the user, and is specifically represented by vibration amplitude, energy, period, and the like. In the following, for the sake of clarity, the description will focus on the amplitude of vibration.

  Next, a case where processing other than vibration is executed will be described. The communication unit 118 and the touch input unit 117 are connected to the processing unit 150. The processing unit 150 acquires touch information on the touch panel 116 from the touch input unit 117 and executes a corresponding software program. For example, the processing unit 150 executes a process corresponding to an item designated by the user's touch. In addition, when the processing unit 150 receives an incoming e-mail notification from the communication unit 118, the processing unit 150 instructs the acquisition of the e-mail. The processing unit 150 instructs the display control unit 152 to display information to be displayed on the touch panel 116, and the display control unit 152 displays the information on the touch panel 116.

  FIG. 3 is a top view of the vibration motor 110. FIG. 3 shows a state where the cover 70 is removed. 4 is a cross-sectional view taken along line AA in FIG. Hereinafter, the configuration of the vibration motor 110 will be described with reference to FIGS. 3 and 4. The vibration motor 110 includes a laminated substrate 10 having a first planar coil 12a and a second planar coil 12b, which are collectively referred to as a coil 12, a permanent magnet 20 that constitutes a movable portion, a guide frame 30, and a first plate. The spring 42 and the second leaf spring 44 and a cover 70 (not shown in FIG. 3) are provided. Hereinafter, of the surfaces of the laminated substrate 10, the surface on which the permanent magnet 20 is mounted is referred to as the upper surface, and the opposite surface is referred to as the lower surface. Further, for convenience of explanation, consider a case where the lower surface of the laminated substrate 10 faces the ground surface and gravity works downward.

  The laminated substrate 10 is a substrate obtained by laminating a first insulating resin layer 52, a wiring layer 54 on which the coil 12 is formed, and a second insulating resin layer 56 in this order from the upper surface side. The first insulating resin layer 52 is an insulating layer formed of a resist material or the like. The wiring layer 54 includes a first planar coil 12a and a second planar coil 12b. The first insulating resin layer 52 and the second insulating resin layer 56 insulate the first planar coil 12a and the second planar coil 12b included in the wiring layer 54 from the outside.

  Both the first planar coil 12 a and the second planar coil 12 b are flat spiral coils, and are arranged so that the surfaces of the coils are parallel to the upper surface 10 a of the multilayer substrate 10. Here, the term “parallel” includes not only the state of being parallel to each other but also the state of being deviated from the state of being parallel to such an extent that the permanent magnet 20 does not hinder the movement. One end corresponding to the center of the spiral of the first planar coil 12a is connected to the first connection wiring 62, and one end corresponding to the outside of the spiral of the first planar coil 12a is connected to the second connection wiring 64. One end corresponding to the center of the spiral of the second planar coil 12 b is connected to the fourth connection wiring 68, and one end corresponding to the outside of the spiral of the second planar coil 12 b is connected to the third connection wiring 66. The first planar coil 12a and the second planar coil 12b are arranged apart from each other along the moving direction of the permanent magnet 20.

  The first connection wiring 62 and the fourth connection wiring 68 are grounded through wiring in the mobile terminal device 100. Both the second connection wiring 64 and the third connection wiring 66 are connected to the input end 16. The input terminal 16 is connected to the second switch 132 of the control unit 114, and the drive voltage S5 is applied. The direction of the spiral winding of the first planar coil 12a is different from the direction of the spiral winding of the second planar coil 12b. In such a configuration of the coil 12, when a drive current is passed from the input end 16, magnetic fluxes in opposite directions are generated in the first planar coil 12a and the second planar coil 12b. The direction of the magnetic flux generated in each coil 12 is reversed when the polarity of the drive current is reversed. As a result, the direction of the magnetic flux generated by each coil 12 also varies with time in accordance with the temporal variation of the polarity of the drive current.

  The permanent magnet 20 is formed in a disc shape having a diameter of 10 mm and a thickness of 1.4 mm made of a ferromagnetic material such as ferrite or neodymium. The permanent magnet 20 is magnetized in the thickness direction, the magnetic pole surface 20N facing the top surface 10a of the multilayer substrate 10 is an N pole, and the magnetic pole surface 20S opposite to the magnetic pole surface 20N is an S pole. . And the permanent magnet 20 switches the upper surface 10a side of the laminated substrate 10 by the arrangement direction of the coil 12 (in the direction of the arrow A1 or the arrow A2) by switching the magnetic force between each of the coils 12 and the N pole between the attractive force and the repulsive force. Direction).

  The guide frame 30 is provided on the upper surface 10 a of the multilayer substrate 10 so as to surround the arrangement of the permanent magnets 20 and the coils 12. The guide frame 30 is a rectangular frame having a certain width, and is formed of a nonmagnetic material such as aluminum or plastic. The length of the inner peripheral surface 30a of the guide frame 30 in the short direction is 10.5 mm, and is formed to be slightly larger than the diameter of the permanent magnet 20. Further, the length of the inner peripheral surface 30a in the longitudinal direction is 13.5 mm, and is formed so as to give a margin in the distance between the permanent magnet 20 and the inner peripheral surface 30a.

A first leaf spring 42 is provided on one short side of the guide frame 30, and a second leaf spring 44 is provided on the other short side. Each leaf spring is a spring having a thickness of 350 μm, a length of 10 mm, and a width of 1.2 mm made of a non-magnetic material such as PET (PolyEthylene Terephthalate). One end of each of the first plate spring 42 and the second plate spring 44 is embedded in the guide frame 30. The permanent magnet 20 is sandwiched from the side surfaces by the other ends of the first plate spring 42 and the second plate spring 44. By doing so, each leaf spring can be bent and deformed with the attachment portion to the guide frame 30 as a supporting point, and has a function of biasing the permanent magnets 20 toward the other leaf spring. Each leaf spring holds the permanent magnet 20 at a substantially central portion in the longitudinal direction of the guide frame 30 in a stationary state (a state where no current is passed through the coil 12). Then, when the permanent magnet 20 reciprocates on the upper surface 10 a of the multilayer substrate 10, the first leaf spring 42 and the second leaf spring 44 are alternately pressed by the permanent magnet 20. As a result, pressure is transmitted from these leaf springs to the guide frame 30. As a result, the guide frame 30 and the entire vibration motor 110 including the guide frame 30 vibrate.
A cover 70 is bonded to the upper surface 30b of the guide frame 30 to prevent the permanent magnet 20 from popping out.

  If such a vibration motor 110 is used, the vibration motor as the vibration source can be thinned, which contributes to further thinning of the mobile terminal device 100.

Here, the relationship between the vibration amplitude of the vibration motor 110 and the frequency of the drive voltage will be described. The amplitude of vibration of the vibration motor 110 is adjusted using the resonance phenomenon of the vibration motor 110. In general, it is known that even when a drive voltage having the same amplitude is supplied to a motor, the amplitude of vibration of the motor varies depending on the frequency. In particular, it is known that there is one or a plurality of driving voltage frequencies at which the amplitude of the vibration takes a maximum value, and such a phenomenon is called motor resonance. Frequency of the drive voltage as the amplitude of the vibration takes the maximum value is referred to as the resonance frequency f _0.

FIG. 5 is a schematic graph showing how the vibration motor 110 resonates. The horizontal axis indicates the frequency of the drive voltage, and the vertical axis indicates the amplitude of vibration of the vibration motor 110. In FIG. 5, the case where the amplitude of the drive voltage is constant at any frequency is considered. As described above, the amplitude of the vibration of the vibration motor 110 has a peak at the resonance frequency f _0. The vibration control unit 130 sets the first frequency f ₁ corresponding to the user's touch on the touch panel 116 so as to deviate from the resonance frequency f ₀ as shown in FIG. Further, the second frequency _{f 2} corresponding to the incoming set to the resonance frequency _{f 0.} Or it sets so that it may correspond to the peak top vicinity of the amplitude of vibration of vibration motor 110.

The operation of the mobile terminal device 100 configured as described above will be described. FIG. 6 is a flowchart showing processing in the mobile terminal device 100. The accepting unit 112 accepts an input operation such as an input to the touch panel 116 by the user or an incoming e-mail (S202). The receiving unit 112 determines whether the input operation is a touch or an incoming call (S204). When it is due to touch (touch in S204), the control unit 114 turns on the second switch 132 (S206). Vibration motor 110 is driven by the amplitude Vd, the first frequency _{f 1} of the drive voltage S5 (S208). Here, from FIG. 5, the vibration amplitude of the vibration motor 110 at the first frequency f ₁ is smaller than the vibration amplitude at the second frequency f ₂ at the time of incoming e-mail. The controller 114 turns off the second switch 132 after the touch vibration period T1 has elapsed (S210).

When the input operation accepted by the accepting unit 112 is due to an incoming call (incoming call in S204), the control unit 114 switches the first switch 128 so that the second terminal 136 and the third terminal 138 are connected (S212). . The mode voltage signal S3 input to the vibration control unit 130 is switched from the first voltage V1 to the second voltage V2 (S214). Vibration control unit 130 switches the frequency of the original drive voltage S4 for outputting the first frequency _{f 1} to the second frequency _{f 2} (S216). After the delay time τ has elapsed since the arrival of the incoming call, the control unit 114 turns on the second switch 132 (S218). Vibration motor 110 is driven amplitude Vd, at the first frequency _{f 2} of the drive voltage S5 (S220). Here, since the second frequency f ₂ is set to the resonance frequency f ₀ of the vibration motor 110 from FIG. 5, the vibration that has a larger amplitude than the vibration of the vibration motor 110 when touching the touch panel 116 and is easy for the user to detect. It becomes.

The control unit 114 turns off the second switch 132 after the incoming vibration period T2 has elapsed (S222). The controller 114 repeats turning on and off the second switch 132 (S224). At this time, the repetition cycle of ON / OFF is the incoming vibration cycle T3. The control unit 114 turns off the second switch 132 after a predetermined period T4 after receiving the incoming call to end the on / off repetition, and connects the first terminal 134 and the third terminal 138 to the first switch 128. (S226). The mode voltage signal S3 input to the vibration control unit 130 is switched from the second voltage V2 to the first voltage V1 (S228). Vibration control unit 130 switches the frequency of the original drive voltage S4 for outputting the second frequency _{f 2} to the first frequency _{f 1} (S230). In this way, the control unit 114 returns to the touch standby state of the touch panel 116.

  Next, the operation of the vibration motor 110 will be further described. When the second switch 132 is off, no voltage is applied to the first planar coil 12a and the second planar coil 12b, and the permanent magnet 20 sandwiched between the first leaf spring 42 and the second leaf spring 44. Is stationary at approximately the center in the longitudinal direction of the guide frame 30 as shown in FIG.

If the second switch 132 is turned on, from the input terminal 16, the driving voltage S5, the polarity is reversed at a first frequency _{f 1} or the second frequency _{f 2} have an amplitude Vd is supplied. Then, magnetic flux is generated in the first planar coil 12a and the second planar coil 12b in a direction perpendicular to the coil surfaces, that is, a direction perpendicular to the upper surface 10a of the multilayer substrate 10. Here, the direction of the magnetic flux generated in the first planar coil 12a is opposite to the direction of the magnetic flux generated in the second planar coil 12b.

  When a drive current flows from the input end 16 toward the first connection wiring 62 and the fourth connection wiring 68, the upper surface of the first planar coil 12a is the S pole and the upper surface of the second planar coil 12b is the N pole. . Since the surface of the permanent magnet 20 facing the laminated substrate 10 is an N pole, a magnetic attractive force is applied to the permanent magnet 20 by the first planar coil 12a and a magnetic repulsive force is applied by the second planar coil 12b. Then, a force is applied to the permanent magnet 20 to move the upper surface 10 a of the laminated substrate 10 toward the first planar coil 12 a side by pushing the first leaf spring 42 along the longitudinal direction of the guide frame 30. When the direction of the drive current is reversed, the upper surface of the first planar coil 12a is an N pole, and the upper surface of the second planar coil 12b is an S pole. Therefore, the permanent magnet 20 has a force that moves the upper surface 10a of the multilayer substrate 10 to the second planar coil 12b side by pushing the second leaf spring 44 along the longitudinal direction of the guide frame 30. . In this way, the permanent magnet 20 reciprocates with respect to the periphery thereof at substantially the same frequency as the inversion of the drive voltage S5. Since the mass of the permanent magnet 20 is not negligible with respect to the surrounding mass, the vibration motor 110 as a whole vibrates in accordance with the reciprocating movement of the permanent magnet 20.

  In the mobile terminal device 100 according to the present embodiment, for example, the following effects can be obtained.

  (1) The control unit 114 is configured to use the same vibration motor 110 when the accepting unit 112 accepts an input operation by receiving an e-mail and when an accepting operation by a touch panel operation is accepted. Therefore, it is not necessary to prepare a separate motor for each vibration mode, and the volume occupied by the vibration generating motor in the mobile terminal device 100 can be reduced. In addition, the control circuit configuration can be simplified, and the mobile terminal device 100 can be downsized and the number of components can be reduced.

  (2) The vibration amplitude at the time of manual input such as touch panel operation is configured to be smaller than the vibration amplitude at the time of incoming e-mail. As a result, the response speed, which is the time required for the vibration motor 110 to reach a predetermined vibration amplitude when the touch panel is operated, can be increased. Can be notified of incoming mail. In addition, during manual input such as when operating a touch panel, vibration is not generated as much as when an incoming call is received, and therefore it is easy to perform an input operation. Therefore, the operability of the mobile terminal device 100 is improved and the commercial value is increased.

  (3) By using the resonance phenomenon of the motor and changing the frequency of the driving voltage, the amplitude of the vibration is changed while the amplitude of the driving voltage remains constant. Therefore, desired vibration control can be realized with a simpler circuit.

(4) The vibration control unit 130 outputs the drive voltage (Vd, f ₁ ) corresponding to the vibration mode at the time of the touch panel operation to the second switch 132 when the reception unit 112 is waiting for the input operation. Therefore, when the mobile terminal device 100 is vibrated in response to a touch on the touch panel, it is only necessary to turn on the second switch 132. As a result, the mobile terminal device 100 having a fast reaction speed and high operability can be realized.

  (5) When the acceptance of the touch on the touch panel 116 and the acceptance of the incoming call occur almost simultaneously, the mobile terminal device 100 gives priority to the driving of the vibration motor based on the acceptance of the touch. Therefore, the touch sensation is not interrupted by the incoming call signal during the touch panel operation such as character input, so that the touch panel operation can be continued without a sense of incongruity.

(6) In the incoming call control unit 122, the delay time τ is determined in consideration of the processing time in the first switch 128 and the vibration control unit 130. Thus, the timing at which the vibration control unit 130 generates the drive voltage of the second frequency f ₂ corresponding to the incoming e-mail and the timing at which the vibration period setting unit 124 turns on the second switch 132 can be adjusted. it can. Note that the vibration control unit 130 generates the drive voltage of the second frequency f ₂ corresponding to the incoming E-mail after the incoming control unit 122 detects the rising edge of the incoming signal S6. You may set longer than the time until completion. In this case, it is possible to prevent the vibration period setting unit 124 from turning on the second switch 132 before the vibration control unit 130 generates the drive voltage of the second frequency f ₂ corresponding to the incoming email.

  (7) Since the mobile terminal device 100 differs in the amplitude (degree) of vibration at the time of incoming call and the amplitude of vibration at the time of touch panel operation, it is easy for the user to determine what operation is being performed. Excellent operability and high commercial value.

  The configuration and operation of the mobile terminal device 100 according to the embodiment has been described above. It is to be understood by those skilled in the art that these embodiments are exemplifications, and that various modifications can be made to combinations of the respective components, and such modifications are also within the scope of the present invention.

  In the present embodiment, the case has been described in which the amplitude of the driving voltage for driving the vibration motor 110 is constant, and the amplitude of the vibration is adjusted by changing the frequency, but the present invention is not limited to this. For example, the power supplied to the vibration motor 110 may be adjusted by changing the voltage, current, and the like. In this way, various variations of control modes are possible.

  In the present embodiment, the touch detection unit 120 generates a pulse in the touch detection signal S1 in response to the user touching the touch panel 116, and the vibration period setting unit 124 detects a pulse in the touch detection signal S1 and a predetermined touch vibration period. Although the case where the second control signal S2 is set to the high level only by T1 has been described, the present invention is not limited to this. For example, when the vibration motor 110 is continuously vibrated only while the user is touching, the touch sensing unit 120 continuously sets the touch sensing signal S1 to the high level while sensing the touch. The vibration period setting unit 124 may set the second control signal S2 to a high level while the touch detection signal S1 is at a high level. In this case, vibration is generated at the moment when the user touches the touch panel, and the vibration stops at the moment when the finger is released from the touch panel. Therefore, the mobile terminal device 100 with higher operability is realized.

  In the present embodiment, the case where the mobile terminal device 100 includes two modes of the touch panel operation vibration mode and the incoming call vibration mode has been described. However, the present invention is not limited to this, and other vibration modes may be set. At this time, if the configuration is such that the third voltage V3 other than the first voltage V1 and the second voltage V2 can be selected by the voltage generator 126 and the first switch 128, such other vibration modes can be easily set. . Further, the vibration amplitude in the touch panel operation vibration mode may be set to be minimum. In this case, since the reaction speed can be increased with respect to a touch operation that requires more responsiveness, a mobile terminal device with high operability is realized.

  Although the present invention has been described based on the embodiments, the embodiments merely show the principle and application of the present invention, and the embodiments are defined in the claims. Needless to say, many modifications and arrangements can be made without departing from the spirit of the present invention.
