Description

  The present invention relates to a vibration generating device and an electronic device, and more particularly to a technology for transmitting information using vibration in an information electronic device such as a smartphone, a mobile phone, a touch panel having a switch function in an automobile, or the like.

  In recent years, information electronic devices such as mobile phones, smartphones, tablets, touch panels having a switch function in automobiles, and the like have come to give various information using vibration.

  For example, in addition to reporting incoming calls and emails with vibration, reporting the arrival of a set time with vibration, when the user touches various buttons on the display of information electronic equipment or on the display, Vibration is used to confirm the operation.

  In addition, in an electronic device such as a game machine, in order to give the user of the game machine various tactile sensations linked to actions and events that occur during the use of the game, various vibrations linked to the actions and events are provided. Generating technology is used.

  Patent Document 1 describes a technique of using a vibration motor in which an eccentric weight is fixed to a rotation shaft of a rotary motor as a technique for generating vibration as described above.

  FIG. 3 is a schematic external configuration diagram of the first vibration motor 71 and the second vibration motor 72 (73) disposed in the smartphone 1 to which the present embodiment is applied.

  FIG. 3A is a schematic external configuration of the first vibration motor 71.

  FIG. 3B is a schematic diagram of the external configuration of the second vibration motor 72.

  FIG. 3C is a schematic external configuration diagram of a second vibration motor 73 which is a modification of the second vibration motor.

  First, the first vibration motor 71 will be described with reference to FIG.

  The first vibration motor 71 is a vibration motor including at least a motor 710 and a first eccentric weight 711.

  A bearing is fixed inside the motor 710, and the rotating shaft is rotatably supported by the bearing. A first eccentric weight 711 is fixed to the rotation shaft of the motor 710.

  In the present embodiment, the first vibration motor 71 is used to report the arrival of an incoming call or an alarm time.

  Next, the second vibration motor 72 will be described with reference to FIG.

  The second vibration motor 72 includes at least a motor 710 having the same standard as the first vibration motor 71 and a second eccentric weight 712 having a smaller radius than the first eccentric weight 711. With this configuration, the second eccentric weight 712 of the second vibration motor 72 is lighter than the first eccentric weight 711 of the first vibration motor 71. For this reason, the first vibration motor 71 and the second vibration motor 72 have different time constants.

  In the present embodiment, the second vibration is used for notification for the user to touch the touch panel 8 (input / output unit 80) of the smartphone 1 with a finger and to inform the user that the smartphone 1 has detected an input by the contact. A motor 72 is used.

  By reducing the weight of the second eccentric weight 712, the time constant of the second vibration motor 72 is reduced. Then, when the first vibration motor 71 and the second vibration motor 72 are driven with the same voltage, the second vibration motor 72 has better responsiveness and can suppress current consumption particularly at the time of vibration activation.

  Next, the 2nd vibration motor 73 which is a modification of a 2nd vibration motor is demonstrated using FIG.3 (c).

  The second vibration motor 73 includes a motor 710 having at least the same standard as the first vibration motor 71 and a second eccentric weight 713 in which the first eccentric weight 711 has a shorter axial length than the first eccentric weight 711. To do. With this configuration, the second eccentric weight 713 of the second vibration motor 73 is lighter than the first eccentric weight 711 of the first vibration motor 71. For this reason, the first vibration motor 71 and the second vibration motor 73 have different time constants.

  Hereinafter, the embodiment will be described using only the second vibration motor 72, but the second vibration motor 73 can be adopted in place of the second vibration motor 72 in all the description. Unless otherwise specified, the description of the second vibration motor 72 is also described for the second vibration motor 73, and the drawings are denoted by reference numerals and description thereof is omitted.

  In the example described above, the weight of the second eccentric weight 712 is adjusted to be smaller than the weight of the first eccentric weight 711 by reducing the volume of the second eccentric weight 712 included in the second vibration motor 72. However, it is not limited to this.

  For example, the material for manufacturing the first eccentric weight 711 and the material for manufacturing the second eccentric weight 712 may be different. Thereby, even if the 1st eccentric weight 711 and the 2nd eccentric weight 712 are the same volume, the weight of the 2nd eccentric weight 712 can be comprised lighter than the weight of the 1st eccentric weight 711.

  Alternatively, not only the second eccentric weight 712 but also the entire size of the second vibration motor 72 is made smaller than the entire size of the first vibration motor 71, so that the second vibration motor 71 can be made to be smaller than the weight of the first vibration motor 71. The weight of the second vibration motor 72 may be reduced within a range in which the weight of the second vibration motor 72 can be reduced and the time constant of the second vibration motor 72 can be set small.

  With the configuration described above, in the present embodiment, the torque of the second vibration motor 72 can be suppressed more than the first vibration motor 71, and the power consumption can be suppressed.

  As described above, in the present embodiment, the first vibration motor 71 is used to notify by large vibration. On the other hand, using the second vibration motor 72 having a time constant smaller than that of the eccentric weight 711 of the first vibration motor 71, notification different from notification using the first vibration motor 71 is performed.

  With this configuration, notification by large vibration is possible, but the event interval is short, and for other events that need to be vibrated and reported as soon as the event occurs, notification by vibration with high responsiveness and responsiveness is possible. to enable.

  In the present embodiment, as a first event to be notified using the first vibration motor 71, an incoming call ("(i)" described above) and an alarm time arrival ("(ii)" described above) are set. An example will be described.

  If the incoming call is the first event, the time when the CPU 10 detects the incoming call to the smartphone 1 is the first event occurrence, and the period during which the incoming call has continued since the first event occurrence is the first event. The notification period.

  If the arrival of the alarm time is the first event, the time when the CPU 10 detects the arrival of the alarm time is set as the time of occurrence of the first event, and a predetermined period from the time of occurrence of the first event is the first event notification period. And The predetermined period may be set in advance such as 1 minute, 3 minutes, 5 minutes, etc. from the occurrence of the event, or may be predetermined by the user when receiving an alarm time setting. You may make it the structure which also receives the setting of a period.

  In the present embodiment, a case where contact or pressing (the above-mentioned “(iv)”) is set as an example of the second event to be notified using the second vibration motor 72 (73) will be described. . In this case, the time when the touch panel 8 detects contact or pressing is the time when the second event occurs, and the period during which contact or pressing is performed is the second event notification period.

  In the smartphone 1 according to the present embodiment, a vibration mode of “notify by vibrating the smartphone 1 when an incoming call” is set. This setting is made when the smartphone 1 receives a setting such as “when incoming: vibration on” from the user via the input / output unit 80 and stores the setting information in the setting information database 43.

  When the vibration setting for this incoming call is stored as ON, in this embodiment, when the smartphone 1 detects the incoming call, the smartphone 1 drives the first vibration motor 71 to generate vibration.

  Hereinafter, the operation performed by the smartphone 1 will be described as being equivalent to the operation performed by the CPU 10 of the smartphone 1 when no particular distinction is required.

  Similarly, in the smartphone 1 according to the present embodiment, a vibration mode of “notify by vibrating the smartphone 1 when the alarm time comes” is set. This setting is also made by the smartphone 1 receiving a setting such as “alarm: vibration on” from the user via the input / output unit 80 and storing the setting information in the setting information database 43.

    When the vibration setting for the alarm is turned on and stored, in the present embodiment, when detecting the arrival of the alarm time, the smartphone 1 drives the first vibration motor 71 to generate vibration.

  Similarly, in the smartphone 1 according to the present embodiment, a vibration mode of “notifying the smartphone 1 by vibrating when the touch panel 8 detects contact or press” is set. This setting is also made by the smartphone 1 receiving a setting such as “screen touch: vibration on” from the user via the input / output unit 80 and storing the setting information in the setting information database 43.

  When the vibration setting for the screen touch is stored as ON, in the present embodiment, when detecting the touch on the screen, the smartphone 1 drives the second vibration motor 72 to generate vibration. Touch is used in the same meaning as pressing or touching by a user's finger.

  In the present embodiment, the above-described vibration on setting and vibration off setting are configured to be selectable.

  In the present embodiment, the first event and the second event are described above, but the present invention is not limited to this. In addition, it is possible to appropriately set the correspondence between vibration and event desired by the user.

  In that case, it is preferable to store in advance a list / table of events that can be notified using vibration, which can generally occur, in the setting information database 43 of the storage unit 40 of the smartphone 1. And what is necessary is just to comprise so that a user can select and set the correspondence of each vibration motor and each event at the time of various settings of the smart phone 1. FIG.

  Alternatively, in addition to the event stored in the storage unit 40, a configuration in which the user's unique event registration can be received from the user, and a setting for combining the event and each vibration motor is stored in the setting information database 43. Also good.

  In view of the usage scene of the smartphone 1, the second event such as touch (contact) or pressing of the touch panel 8 is more likely to occur more frequently than the first event such as an incoming call or an alarm time. That is, the second vibration motor 72 is likely to be driven more frequently than the first vibration motor 71.

  For the second vibration motor 72 that is used frequently in this manner, the weight and moment of inertia of the second eccentric weight 712 are reduced, or the weight and moment of inertia of the second eccentric weight 712 are reduced and the torque of the second vibration motor 72 is reduced. Since the power consumption necessary for driving the second vibration motor 72 can be reduced by reducing the size within a range where there is no problem in use, the power consumption reduction effect of the smartphone 1 as a whole can be further enhanced. .

  The above description has focused on generating vibration by driving the first vibration motor 71 having large vibration when an incoming call or an alarm time comes. However, if the user does not wear the smartphone 1 directly in his / her pocket, puts it on the desk, or operates it with his / her hand, large vibration of the smartphone 1 is necessary. Often not. Rather, a large vibration of the smartphone 1 generated in a state of being placed on the desk can cause unpleasant sound for the user due to the contact between the desk and the smartphone 1. Moreover, the large vibration of the smartphone 1 in the state that the user has in his / her hand becomes vibration more than necessary for the user during operation, which may cause surprise or discomfort to the user.

  Assuming such a case, the smartphone 1 can accept a selection from the user to drive the second vibration motor 72 when an incoming call or an alarm time comes. As a result, it is possible to eliminate an unpleasant feeling of the user and the surrounding people and to reduce current consumption.

Alternatively, instead of selection from the user, a sensor (not shown) included in the smartphone 1 detects the posture of the smartphone 1, and based on the detection result, the sensor is in a pocket (vertically placed state), on a desk, or hand The smartphone 1 may determine whether the second vibration motor 72 is in a horizontal position, and may select the driving of the second vibration motor 72 when an incoming call or an alarm time arrives.
(Arrangement of each vibration motor)
The first vibration motor 71 and the second vibration motor 72 described above are built in the smartphone 1 as follows.

  FIG. 4 is a diagram for explaining a vibration generating device included in the smartphone 1 to which the present embodiment is applied.

  The dotted line m represents the rotation axis of the first vibration motor 71, and the dotted line n represents the rotation axis of the second vibration motor 72 as a virtual axis.

  As shown in FIG. 4, the first vibration motor 71 and the second vibration motor 72 are mounted on a substrate 700 such as an electronic circuit as an example, and are mounted on the surface of the substrate 700 by being fixed by, for example, cream solder. .

  At this time, the first vibration motor 71 is fixed to the substrate 700 so that the rotation axis (dotted line m) coincides with the thickness direction of the substrate 700. The second vibration motor 72 is fixed to the substrate 700 so that the rotation axis (dotted line n) is parallel to the fixed surface of the substrate 700.

  In the example shown in FIG. 4, the angle formed by the rotation axis (dotted line m) of the first vibration motor 71 and the rotation axis (dotted line n) of the second vibration motor 72 is a right angle. It is not necessary to arrange so.

  Therefore, it is preferable that the second vibration motor 72 is fixed to the back side of the liquid crystal display unit 82 in such a state that the axis of rotation (dotted line n) is taken in a direction parallel to the panel surface of the liquid crystal display unit 82.

  With this arrangement, that is, the direction of vibration generated by the second vibration motor 72 is perpendicular to the surface of the liquid crystal display unit 82 (that is, the direction in which the liquid crystal display unit 82 (panel) is bent), Even if the vibration generated by the two-vibration motor 72 is small, the liquid crystal display unit 82 can be efficiently vibrated.

  Further, the arrangement on the substrate 700 is not limited to the positional relationship shown in FIG. For example, if the substrate 700 is rectangular, it may be arranged on a diagonal line, or may be arranged in parallel in the short side direction or the long side direction. Even if the substrate 700 is substantially circular, it can be arranged in various positional relationships.

  Or, contrary to the above, the rotation axis (dotted line n) of the second vibration motor 72 coincides with the thickness direction of the substrate 700, and the rotation axis (dotted line m) of the first vibration motor 71 is on the substrate 700. Both vibration motors may be fixed to the substrate 700 so as to be parallel to the fixed surface.

  In any case, the substrate 700 is disposed on the smartphone 1 such that the thickness direction of the substrate 700 and the thickness direction of the smartphone 1 coincide. By arranging in this way, the arrangement surface on the substrate 700 where the first vibration motor 71 and the second vibration motor 72 are arranged and the display surface of the liquid crystal display unit 82 become substantially parallel. With this configuration, vibrations from the first vibration motor 71 and the second vibration motor 72 are transmitted to the liquid crystal display unit 82 via the substrate 700.

  Thus, the smartphone 1 according to the present embodiment is arranged so that the rotation axis of the first vibration motor 71 is perpendicular to the display surface of the liquid crystal display unit 82 of the smartphone 1. On the other hand, the rotation axis of the second vibration motor 72 is arranged to be parallel to the display surface of the liquid crystal display unit 82 of the smartphone 1.

  Further, the first eccentric weight 711 and the second eccentric weight 712 are arranged such that the arrangement directions with respect to the substrate 700 are different from each other. Then, the vibration directions of the substrate 700 (display surface of the liquid crystal display unit 82) generated when the vibration of each eccentric weight is transmitted to the substrate 700 are also different. As a result, the direction of vibration generated by causing the smartphone 1 to vibrate the first vibration motor 71 and the direction of vibration generated by vibrating the second vibration motor 72 can be made different.

  With this configuration, the direction of vibration and how the vibration is transmitted in the smartphone 1 can be different between when the first event is notified and when the second event is notified. That is, it is possible to make it easier to distinguish the events that have occurred due to the difference in each vibration.

  Also, suppose that the first event and the second event occur almost simultaneously and the first vibration motor 71 and the second vibration motor 72 are driven simultaneously. In that case, various vibrations that are transmitted differently can be generated depending on the combination of the vibration directions of the smartphone 1 by each vibration motor.

Thus, in this embodiment, since the variation of the vibration which the smart phone 1 generates increases, the information which can be transmitted using a vibration to a user can be diversified.
(Modification)
FIG. 5 is a diagram for explaining a modification of the above-described embodiment.

  As shown in FIGS. 5A and 5B, the axes of the rotation axes of the first vibration motor 71 and the second vibration motor 72 are both parallel to the fixed surface of the substrate 700, and the first vibration. The rotating shaft axis (dotted line m) of the motor 71 and the rotating shaft axis (dotted line n) of the second vibration motor 72 are fixed to the substrate 700 so as to have an angle.

  As shown in FIG. 5A, the two vibration motors (71, 72) may be arranged so that the angles formed by the two axes (dotted line m, dotted line n) are substantially perpendicular. More preferred.

  As described above, the smartphone 1 according to this modification is disposed so that the rotation axes of the first vibration motor 71 and the second vibration motor 72 are both parallel to the display surface of the liquid crystal display unit 82 of the smartphone 1. .

  For this reason, vibration can be efficiently generated without increasing the thickness of the smartphone 1.

  Alternatively, as shown in FIG. 5C, the first vibration motor 71 and the second vibration motor 72 are fixedly disposed so that the axis directions of the rotation axes thereof coincide with the thickness direction of the substrate 700. May be.

  In the above description, the first vibration motor 71 and the second vibration motor 72 have been described by way of example of a rotary motor that rotates an eccentric weight whose center of gravity is eccentric with respect to the rotation axis. However, the present invention is not limited to this. Either one or both of the motors may be a linear motor that reciprocates the weight in the horizontal direction (uniaxial direction). The linear type motor includes an electromagnetic type linear motor driven by an electromagnetic force and a type that generates vibration by deformation of a piezoelectric element.

  When any one of the motors is a linear type motor, it is desirable that the second vibration motor 72 is a linear type motor. Also in this case, it is preferable that the time constant of the second vibration motor 72 is smaller than the time constant of the first vibration motor 71 and the responsiveness is good.

  The upper limit of the frequency at which a person feels vibrations efficiently is about 150 Hz. However, in the case of a linear motor that is equivalently composed of a weight and a spring, if it is vibrated (resonated) at 150 Hz, it is large. In order to obtain the vibration force, the size is increased as compared with a rotary motor. On the other hand, when a relatively small vibration force is sufficient, a linear motor can be obtained with a small size and excellent response characteristics. Therefore, it is effective to use the second vibration motor 72 in the present invention as a linear motor. is there.

  In this case, the vibration direction by the linear motor is preferably the in-plane direction (horizontal direction) of the touch panel, that is, the direction orthogonal to the direction of the finger pressure on the touch panel of the user. According to this, the lateral force field phenomenon can be used, and various senses can be given to the user's finger by vibration. Therefore, when the user touches the touch panel with a finger and transmits the input by the contact to the user, various senses can be transmitted.

From the same idea, it is also effective to reverse the roles of the first vibration motor 71 and the second vibration motor 72 in FIG. That is, in FIG. 4, the first vibration motor 71 is arranged so that the rotation axis (dotted line m) coincides with the thickness direction of the substrate 700, and the second vibration motor 72 has the rotation axis (dotted line n) fixed on the substrate 700. However, the first vibration motor 71 is arranged so that the axis of rotation (dotted line n) is parallel to the fixed surface of the substrate 700, and the second vibration motor 72 is arranged along the axis of rotation ( You may arrange | position so that a dotted line m) may correspond with the thickness direction of the board | substrate 700. FIG. However, the second vibration motor 72 is desirably a flat motor whose length in the direction of the axis of the rotation axis is shorter than the length of the outer diameter. With such a flat motor, the thickness of the electronic device can be reduced and the thickness can be reduced. Further, in an electronic device, a relatively large space can be taken in a plane perpendicular to the thickness, that is, in a plane direction of the substrate 700, so that even if the outer diameter of the second vibration motor 72 is slightly increased, there is a problem. There is no. The torque can be increased by increasing the outer diameter of the second vibration motor 72 (than the first vibration motor 71), and the responsiveness can be increased (as compared with the first vibration motor 71). Become. Therefore, when the user touches the touch panel with a finger and transmits the input by the contact to the user, it is possible to respond instantaneously according to the contact of the user's finger. Of course, it is also effective to reduce the weight of the weight of the second vibration motor.
(Vibration pattern)
FIG. 6 is a diagram for explaining a vibration pattern according to the vibration generator.

  FIG. 6A shows a typical vibration pattern of the first vibration motor 71.

  In the present embodiment, the first event is associated with an event such as an incoming call or an alarm that has a relatively long notification duration from the occurrence of the event.

  Therefore, the smartphone 1 controls the power source of the first vibration motor 71 to be on for a certain period while the first event is being notified (hereinafter referred to as a first event notification period), and then turns off for a certain period. To provide an off section. When the combination of the on section / off section is a combination P1, the smartphone 1 controls the first vibration motor 71 so that the combination P1 is repeated during the first event notification period.

  FIG. 6B shows a typical vibration pattern of the second vibration motor 72.

  In the present embodiment, the second event is associated with an event having a relatively short notification period, such as contact or pressing.

  Therefore, as shown in the pattern A, the smartphone 1 controls the power source of the second vibration motor 72 to be on for a certain period while the second event is being notified (hereinafter, the second event notification period). After that, the power-off is controlled for a period longer than the power-on control period, and the off section is provided. If the combination of the on section / off section is a combination P2, the smartphone 1 controls the second vibration motor 72 so that the combination P2 is repeated during the second event notification period.

  Moreover, as shown in the pattern B, the smartphone 1 frequently switches on / off the power source of the second vibration motor 72 for a certain period during the second event notification period (for example, during the on-period of 0.5 seconds). , Switching from about 3 to 5 times) is performed to provide an ON section having a short ON / OFF cycle, and thereafter, a certain period longer than the ON section is controlled to be OFF to provide a combination P3 that provides an OFF section. Also good. Note that the normal on / off switching is repeated alternately between an on period of 0.5 seconds and 1 second and an off period of 0.5 seconds to 1 second.

  Or as shown in the pattern C, you may make it the structure which continues the control which switches on / off of the power supply of the 2nd vibration motor 72 frequently in a 2nd event alerting | reporting period.

  In any case of FIG. 6, the number of peaks indicating power-on (during vibration) and the number of valleys indicating OFF are merely examples, and are not limited to those illustrated.

  Or it is not the structure which has a vibration pattern by the combination of on / off as mentioned above, and even if it is the 1st vibration motor 71 or the 2nd vibration motor 72, the power supply of each vibration motor is generated with the occurrence of each event. You may make it the structure which continues driving | operating as long as it turns on and alert | reports an event after that (not shown).

  The vibration pattern described above is stored in the setting information database 43 (FIG. 2), and is configured to be associated with each stored event. In that case, the correspondence between each event and each vibration pattern may be received from the user and stored. Alternatively, the association between each vibration pattern and each event may be configured in advance in the smartphone 1.

  When the smartphone 1 detects and notifies the first event and the second event, when the occurrence time of the both events and the notification period do not overlap, the vibration of one of the vibration patterns described above is caused by vibration of each event. Each vibration motor may perform notification.

  In the present embodiment, when the smartphone 1 detects the first event and the second event in an overlapping manner, the smartphone 1 adjusts each vibration motor that notifies each event as follows. That is, when the other event is detected during notification based on one event, the smartphone 1 performs one of the following two adjustments regarding notification of the detected other event.

  Note that the case where the first event and the second event occur overlapped is, for example, “the touch panel 8 is touched at the same timing as the detection of the incoming call (first event) (second event)”. The situation is possible.

  The first adjustment is an adjustment that avoids overlapping of the ON sections of the first vibration motor 71 and the second vibration motor 72. In this adjustment, the smartphone 1 uses a vibration motor that notifies the other event detected later so that the start of the on interval related to the other event detected later becomes the off interval related to the one event detected earlier. Control.

  The second adjustment is an adjustment that avoids the overlap between one off section and the other on section of the first vibration motor 71 and the second vibration motor 72. In this adjustment, the smartphone 1 uses a vibration motor that notifies the other event detected later so that the start of the on interval related to the other event detected later becomes the on interval related to the one event detected earlier. Control.

  Even if the first event and the second event are detected in duplicate, the smartphone 1 does not perform the first adjustment or the second adjustment as described above, and the on interval / off interval related to one event that has occurred first. Regardless of the above, an on-section related to the other event may be started (no adjustment).

  FIG. 7 is a diagram for explaining a vibration state of each vibration motor related to the first adjustment, the second adjustment, and no adjustment described above.

  First, the case of the first adjustment will be described.

  FIG. 7A illustrates an example in which the smartphone 1 performs on-control of the second vibration motor 72 when the first vibration motor 71 is in off-control.

As shown in FIG. 7A, the smartphone 1 immediately follows the second vibration motor 72 even when the second event occurs during the driving (on period) of the first vibration motor 71 based on the first event. Do not drive. That is, the smartphone 1 includes the first vibration motor 71 and the second vibration motor.

The second vibration motor 72 is controlled so that the ON sections of the motor 72 do not overlap.

  The smartphone 1 does not turn on the second vibration motor 72 immediately after the off control of the first vibration motor 71 but turns on the second vibration motor 72 after a predetermined time lag ta. In addition, even if the smart phone 1 provides the time lag ta, the ON section of the first vibration motor 71 and the ON section of the second vibration motor 72 do not overlap each other from the OFF control of the second vibration motor 72 to the next ON control. The clearance tb is controlled.

  By providing this time lag ta, the vibration based on the first vibration motor 71 and the vibration based on the second vibration motor 72 are not continuous, and a section without vibration is created, so the second event occurs during the occurrence of the first event. It is possible to accurately report to the user what has been done / occurs.

  The second vibration motor 72 may be turned on immediately after the first vibration motor 71 is turned off without providing the predetermined time lag ta.

  As described above, in the example illustrated in FIG. 7A, the smartphone 1 performs control without providing a section in which the first vibration motor 71 and the second vibration motor 72 are driven in parallel. The maximum current consumption required when driving (simultaneously) can be suppressed.

  Therefore, in this embodiment, damage to the battery of the smartphone 1 can be reduced and the battery life can be extended.

  Next, the case of the second adjustment will be described.

  FIGS. 7B and 7C illustrate an example in which the smartphone 1 performs on-control of the second vibration motor 72 when the first vibration motor 71 is on-controlled.

  As shown in FIG. 7B, when the time when the second event is detected (second event occurrence) is during the driving of the first vibration motor 71 based on the first event (on section) (on section). The smartphone 1 drives the second vibration motor 72 simultaneously with the detection of the second event. In this configuration, the smartphone 1 controls the clearance tb so that the ON section of the first vibration motor 71 and the ON section of the second vibration motor 72 overlap.

  In addition, as illustrated in FIG. 7C, when the timing when the second event is detected is not driving the first vibration motor 71 based on the first event (in an off section), the smartphone 1 Even if two events are detected, the second vibration motor 72 is not driven immediately, and a time lag ta is provided for the vibration to overlap with the ON section of the first vibration motor 71. Then, the second vibration motor 72 is driven after the time lag ta.

  7B and 7C, the case where the vibration pattern of the second vibration motor 72 is the pattern A (FIG. 6B) has been described as an example, but the present invention is not limited to this. As the vibration pattern of the second vibration motor 72, the pattern B (FIG. 6B) can be similarly configured.

  As described above, in the example described with reference to FIGS. 7B and 7C, the second eccentric weight 712 of the second vibration motor 72 is lighter than the first eccentric weight 711 of the first motor 71. The vibration motor 72 can be more responsive than the first vibration motor 71, and can be configured without significantly consuming current consumption.

  In addition, when the first vibration motor 71 and the second vibration motor 72 are driven in parallel, the smartphone 1 can generate various vibrations by changing the vibration patterns of both. Therefore, even if the second vibration motor 72 is vibrated based on the second event while the first vibration motor 71 is driven based on the first event, a different event occurs depending on the type of vibration (pattern) and the drive timing. Can be effectively reported to the user.

  Next, the case of no adjustment will be described.

  As shown in FIG. 7D, even when the smartphone 1 detects the second event while the first vibration motor 71 is being driven, the second vibration is applied regardless of whether the first vibration motor 71 is on or off. The motor 72 is driven. After that, regardless of the driving of the first vibration motor 71, the second vibration motor 72 is caused to generate vibration based on the second event.

  In addition, although FIG. 7 demonstrated the case where the smart phone 1 detected the 2nd event in the state which detected the 1st event (1st vibration motor 71) previously, it is the same also when the 2nd event is detected previously. It is applicable to.

  However, since the on section related to the first event is longer than the on section related to the second event, the smartphone 1 may be configured to further select the following control.

  That is, regarding the vibration related to the first event detected later, the smartphone 1 can determine the amount of the on-section of the vibration pattern associated with the first event even if the on-section of the second event detected earlier ends. Only the vibration of the first vibration motor 71 is continued. Alternatively, regarding the vibration related to the first event detected later, the vibration of the first vibration motor 71 is forcibly terminated together with the end of the ON interval of the second event.

  Similarly, in the first adjustment described with reference to FIG. 7A, when the second event is detected in the off section related to the first event detected earlier, the smartphone 1 immediately moves the second vibration motor 72. However, both the case where the on-interval of the second event is terminated and the case where the on-interval of the second event is continued and the case where it is forcibly terminated can be adopted.

  FIG. 8 is a diagram for explaining a modification of the above-described vibration state.

  The modification described in the figure is an example in which one of the first vibration motor 71 and the second vibration motor 72 is preferentially driven and the other that is not prioritized is stopped.

  In this modification, the first vibration motor 71 and the second vibration motor 72 are always monitored as to whether or not each vibration motor is on. Then, control is performed to drive the vibration motor set to preferentially vibrate by stopping the other vibration motor being driven.

  This setting is received from the user by the smartphone 1 via the input / output unit 80 and stored in the setting information database 43. Alternatively, the smartphone 1 may be configured in advance with a vibration motor that prioritizes driving (that is, driving does not stop even when events occur). Furthermore, it may be configured to be set in advance and accept change settings from the user.

  FIG. 8 shows, as an example, the driving timing when the second vibration motor 72 is set to be driven with priority over the first vibration motor 71.

  FIG. 8 shows an example in which three different second events occur in one first event notification period. The “first second event notification period”, “second second event notification period”, and “third second event notification period” are respectively the second vibration motors described with reference to FIG. 72 corresponds to a period during which the smartphone 1 vibrates the second vibration motor 72 in any one of the vibration patterns A, B, and C.

  When the smartphone 1 detects the first second event (tA), the first vibration motor 71 is off (the first event has occurred, but the off-period in the vibration pattern of the first vibration motor 71). If there is, the second vibration motor 72 is driven.

  On the other hand, if the smartphone 1 detects the second event for the second time (tB) and the first vibration motor 71 is being driven (the ON section in the vibration pattern of the first vibration motor 71), the first vibration motor After the drive of 71 is stopped, the second vibration motor 72 is driven.

  Note that the predetermined time lag ta described with reference to FIG. 7 may be provided between the drive stop of the first vibration motor 71 and the drive of the second vibration motor 72.

  And the smart phone 1 drives the 1st vibration motor 71, when the 1st event has still continued at the timing (tC) when the 2nd 2nd event was complete | finished.

  Thus, in this modification, the smartphone 1 can accurately report an event with a higher priority to the user by vibration.

  Next, the operation of the smartphone 1 described above will be described.

  FIG. 9 is a flowchart for explaining the vibration operation of the smartphone 1 according to this embodiment.

  The CPU 10 of the smartphone 1 constantly monitors the occurrence of a predetermined event under the state in which the smartphone 1 is turned on (step 5).

  Note that the predetermined event in the present embodiment is, as described above, an incoming call from another terminal (first event), arrival of an alarm time (first event), touch or press on the touch panel 8 (second event). It is.

  When the CPU 10 determines that a predetermined event has not occurred (step 5; N), the CPU 10 continues to monitor the occurrence of the event.

  On the other hand, when it is determined that a predetermined event has occurred (step 5; Y), the CPU 10 determines whether or not the vibration setting is set to ON (step 10). This vibration setting is a setting as to whether or not to perform notification for vibrating the smartphone 1 when an event occurs. Since the CPU 10 stores information (either vibration setting on or vibration setting off) received from the user via the input / output unit 80 in advance in the setting information database 43, the CPU 10 can check the setting information database 43. to decide. This vibration setting can be switched by changing the setting from the user in accordance with the TPO such as the place or time when the smartphone 1 is used. “Vibration setting on” is a setting for performing notification using vibration, and “vibration setting off” is a setting for not performing notification using vibration.

  When the vibration setting is set to OFF (step 10; N), the CPU 10 performs a normal notification process that is a notification performed using sound (step 20), and ends the process related to the notification.

  On the other hand, when the CPU 10 determines that the vibration setting is set to ON (step 10; Y), the CPU 10 determines whether the predetermined event that has occurred is the first event (step 30). To determine whether or not the event is the first event, for example, a list relating to the event is stored in the setting information database 43 and a correspondence table showing which event corresponds to the first event (or the second event) is checked. Is done.

  When determining that the predetermined event that has occurred is the first event (step 30; Y), the CPU 10 drives the first vibration motor 71 to generate vibration (step 40).

  Then, the CPU 10 continues monitoring whether or not the first event has ended (step 50), and returns to step 40 to drive the first vibration motor 71 while the first event does not end (step 50; N). to continue.

  On the other hand, if the CPU 10 determines that the first event has ended (step 50; Y), the notification process using vibration ends.

  When the CPU 10 determines that the predetermined event that has occurred is the second event (step 30; N), the CPU 10 drives the second vibration motor 72 (step 60). Thereby, the smart phone 1 generates a vibration smaller than the vibration by the first vibration motor 71 when the second event occurs.

  Then, the CPU 10 continues to monitor whether or not the second event has ended (step 70), and returns to step 60 to drive the second vibration motor 72 while the second event does not end (step 70; N). to continue.

  On the other hand, when the CPU 10 determines that the second event has ended (step 70; Y), the notification process using vibration ends.

  In the embodiment described with reference to FIG. 9, the operation has been described focusing on one generated event, but monitoring (step 5) of whether or not a predetermined event has occurred is always performed. Therefore, when events that can occur continuously occur one after another or after a certain interval, this processing is performed for each event.

  That is, the second event occurs while the first event is occurring (or the first event occurs while the second event is occurring), and as a result, the first vibration motor 71 and the first event occur. There may be a state in which the two vibration motors 72 are driven substantially simultaneously.

  FIG. 10 is a flowchart for explaining another example of the vibration operation of the smartphone 1 according to the present embodiment.

  The embodiment described in FIG. 10 particularly corresponds to the operation of the vibration combination described in FIG. 7A, and the smartphone 1 is controlled so that the first vibration motor 71 and the second vibration motor 72 are not driven simultaneously. To do. For example, the first event associated with the first vibration motor 71 may be employed when the first event associated with the second vibration motor 72 is more important or urgent than the second event associated with the second vibration motor 72.

  In FIG. 10, the same operations as those described in FIG. 9 are denoted by the same step numbers and the description thereof is omitted.

  In the embodiment described with reference to FIG. 10, when it is determined that the predetermined event that has occurred is not the first event (step 30; N), the CPU 10 determines whether or not the first vibration motor 71 is being driven (step 80). ).

  Note that “the first vibration motor 71 is being driven” in step 80 means that the first vibration motor 71 that has already been driven (powered on) in order to notify the first event that occurred before this event. It is a driving state.

  When the CPU 10 determines that the first vibration motor 71 is already being driven (step 80; Y), the CPU 10 continues to monitor the drive state of the first vibration motor 71.

  On the other hand, when it is determined that the first vibration motor 71 is not being driven (step 80; N), the CPU 10 drives the second vibration motor 72 (step 60).

  At this time, the CPU 10 may be configured to drive the second vibration motor 72 immediately after the determination, or may be configured to be driven with the timing delayed by the predetermined time lag ta described in FIG. Good.

  Further, when the predetermined time lag ta is not provided, it is also possible that the vibration by the first vibration motor 71 and the vibration by the second vibration motor 72 are continuous. Therefore, preferably, different vibration patterns are set for each. Good.

  In FIG. 10, the first vibration motor 71 (first event) is prioritized over the second vibration motor 72 (second event). Conversely, the second vibration motor 72 is prioritized. Configuration is also possible. In that case, it is preferable to add a configuration for determining whether or not the second vibration motor 72 is being driven before the first vibration motor 71 is driven (step 40).

  As described above, in the embodiment described with reference to FIG. 10, the smartphone 1 does not drive the second vibration motor 72 even if the second event occurs while the first vibration motor 71 is driven. The first event associated with the single vibration motor 71 can be notified more accurately using vibration.

  Moreover, power consumption can be reduced by not driving two vibration motors simultaneously.

  Furthermore, by making each vibration pattern (power on / off cycle) different, even if the vibrations by the first vibration motor 71 and the second vibration motor 72 continue, the user can change the event depending on the vibration change. Can be recognized.

  FIG. 11 is a flowchart for explaining the vibration operation of the smartphone 1 according to the present embodiment, and particularly corresponds to the operation of the modified example of the vibration combination described in FIG.

  Also in the present embodiment described using FIG. 11, the smartphone 1 does not drive the first vibration motor 71 and the second vibration motor 72 at the same time as in the embodiment described in FIG. 9.

  However, FIG. 11 illustrates a configuration in which the second vibration motor 72 is driven with priority over the first vibration motor 71. In other words, the second event associated with the second vibration motor 72 can be employed when it is more important or urgent than the first event associated with the first vibration motor 71.

  In addition, about the same operation | movement as the operation | movement demonstrated in FIG. 9 or FIG. 10, the same step number is attached | subjected and description is abbreviate | omitted.

  In the embodiment described with reference to FIG. 11, if it is determined that the first vibration motor 71 is already being driven (step 80; Y), the CPU 10 temporarily ends the first event that occurred at that time. Even if not, the first vibration motor 71 is stopped (step 90). This stop is a so-called interrupt stop. Subsequently, the CPU 10 drives the second vibration motor 72 (step 60).

  Note that “the first vibration motor 71 is being driven” in step 80 is already driven (power-on) in order to notify the first event that occurred before this event, as described in FIG. This is a driving state of the first vibration motor 71 that has been performed.

  Then, the CPU 10 continues to monitor whether or not the second event has ended (step 70). When the CPU 10 determines that the second event has ended (step 70; Y), in this embodiment, the first event is the next event. The process proceeds to a process for determining whether or not the process has been completed (step 50).

    In FIG. 11, the example in which the second vibration motor 72 (second event) has priority over the first vibration motor 71 (first event) has been described, but conversely, the first vibration motor 71 has priority. Configuration is also possible.

  In that case, a configuration of “determining whether or not the second vibration motor 72 is already driven” may be added before the first vibration motor 71 is driven (step 40). Then, “a configuration in which the second vibration motor 72 is stopped and the first vibration motor 71 is driven when the second vibration motor 72 is being driven may be further added.

  As described above, in the embodiment described with reference to FIG. 11, when a second event having a high priority occurs, the smartphone 1 has a priority higher than the second event that occurs before the second event. If the first vibration motor 71 is being driven in response to a low first event, the second vibration is generated in order to notify the second event that occurred most recently by stopping the drive of the first vibration motor 71. The vibration motor 72 is driven.

  For this reason, when notifying the 2nd event with high priority matched with the 2nd vibration motor 72, since both vibration motors do not drive redundantly, more accurate information using vibration is performed. be able to.

  Moreover, power consumption can be reduced by not driving two vibration motors simultaneously.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the described embodiments and modifications, and various modifications can be made within the scope described in each claim.

  In the above-described embodiment, the vibration motor that is driven in response to the first event or the second event can be set to either the first vibration motor 71 or the second vibration motor 72. It can also be set as the structure combined.

  For example, vibrations used to notify the detection of emergency early warnings such as earthquake early warnings, and to notify warnings to users who are trying to perform operations or actions that are prohibited even for input contacts. In order to generate them, the first vibration motor 71 and the second vibration motor 72 may be set as a set and both may be driven simultaneously.

  Alternatively, the detection is performed by adding a configuration such as a contact sensor, a pressure detection sensor, or a temperature sensor that detects that the smartphone 1 is placed on a desk or being held by a user's hand to the smartphone 1. In some cases, the second vibration motor 72 may be driven even if an event that is set to drive the first vibration motor 71 occurs.

  Moreover, you may make it the structure which can set as a 1st event that the smart phone 1 and a user are a non-contact state.

  Moreover, you may make it the structure which can set as a 2nd event that the smart phone 1 and a user are in a contact state.

  Moreover, you may make it the structure which utilizes both the normal alerting | reporting process performed using a sound, and the vibration alerting process performed using a vibration.
