Description

  The present invention relates to an electronic device having a vibration function.

  As an example of the electronic device, a communication terminal such as a mobile phone having a vibration function that notifies an incoming call by vibration is known. The vibration function is realized by operating a motor with an eccentric vibrator (eccentric motor). Here, since the vibration function is for notifying the user of an incoming call by vibration when the ring tone is turned off, the vibration amount is preferably as large as possible. Therefore, the eccentric motor is installed in a place as far as possible from the center of gravity of the communication terminal.

  However, if there is an incoming call when the communication terminal is left on the desk with the vibration function turned on, the communication terminal gradually moves while sliding on the desk due to vibration caused by the vibration operation, and eventually falls from the desk. There is a risk. In view of this, when the vibration amount of the communication terminal is a self-moving vibration amount, a technique for suppressing the vibration amount of the communication terminal to a vibration amount that does not move itself has been proposed.

  Hereinafter, an exemplary embodiment will be described with reference to the drawings.

[First Embodiment]
First, an example of the external configuration of the communication terminal 10 according to the first embodiment will be described with reference to FIG. The communication terminal 10 is, for example, a mobile phone, and an upper housing 20A that a user touches with an ear during a call and a lower housing 20B that the user holds with a hand are connected to be openable and closable around a hinge portion 20C. FIG. 1A shows a view when the upper housing 20A and the lower housing 20B are opened, and FIG. 1B shows a state where the upper housing 20A and the lower housing 20B are closed. The figure when it is made is shown. In general, when a user makes a call, as shown in FIG. 1A, the upper housing 20A and the lower housing 20B are opened, and when waiting for an incoming call, FIG. As shown in FIG. 4, the upper casing 20A and the lower casing 20B are closed.

  As shown in FIG. 1A, on the surface of the upper housing 20A, a menu screen, a liquid crystal panel 21 on which a photographed image is displayed, and a sound emitted from a speaker attached inside are emitted. An earpiece 22 and the like are provided. On the other hand, on the surface of the lower housing 20B, a push button 25 for inputting a telephone number and the like, a mouthpiece 26 for transmitting a user's voice to a microphone attached inside, and the like are provided.

  Further, as shown in FIG. 1B, a liquid crystal panel 27 on which time and patterns are displayed is provided on the surface opposite to the surface on which the liquid crystal panel 21 is attached in the upper housing 20A. Yes. Note that the point G indicates the center of gravity of the communication terminal 10 when the upper housing 20A and the lower housing 20B are closed.

  Generally, a communication terminal such as a mobile phone has a vibration function that notifies an incoming call by vibration of the main body. The vibration function is realized by operating an eccentric motor having an eccentric vibrator attached to a rotating shaft. Since the vibration function is for notifying the user of an incoming call by vibration when the ring tone is turned off, the vibration amplitude is preferably as large as possible. Therefore, the eccentric motor is installed in a place as far as possible from the center of gravity of the main body. For example, also in the example shown in FIG. 1B, the eccentric motor 14 is attached to a place farthest from the center of gravity G in the lower housing 20B. However, when the communication terminal is placed on a hard place such as a desk, when the eccentric motor operates, the communication terminal moves due to the generated vibration. When the rotation shaft of the eccentric motor rotates only in one direction, the communication terminal may gradually move in a certain direction, and eventually fall from the desk or the like.

  Therefore, the communication terminal 10 according to the first embodiment has a motion sensor that detects the movement of the communication terminal due to vibration, and when the movement of the communication terminal is detected by the motion sensor, the communication terminal 10 has been rotated until then. The eccentric motor is rotated in the direction opposite to the direction in which it was moved. This will be specifically described below.

  FIG. 2 is an example of a diagram illustrating an internal configuration of the communication terminal 10 according to the first embodiment.

  As shown in FIG. 2, the communication terminal 10 according to the first embodiment includes a motion sensor 11, a movement information detection circuit 12, a motor control circuit 13, and an eccentric motor 14.

  The motion sensor 11 is a sensor for detecting the movement of the communication terminal 10, and is, for example, a sensor such as an acceleration sensor or a geomagnetic sensor. When detecting the movement of the communication terminal 10, the motion sensor 11 transmits a detection signal to the movement information detection circuit 12. For example, when the motion sensor 11 is an acceleration sensor, a detection signal corresponding to the detected movement direction and acceleration is transmitted to the movement information detection circuit 12.

  Based on the detection signal from the motion sensor 11, the movement information detection circuit 12 detects movement information such as a translational movement amount and a rotational movement amount for the communication terminal 10. Here, the translational movement amount indicates the displacement amount of the communication terminal 10 in the desktop plane, that is, the displacement amount of the gravity center G, and the rotational movement amount indicates the rotation angle of the communication terminal 10 with respect to the gravity center G in the desktop plane. Show. The movement information detection circuit 12 transmits the detected translational movement amount and rotational movement amount to the motor control circuit 13 as movement information. Therefore, the motion sensor 11 and the movement information detection circuit 12 correspond to detection means.

  The motor control circuit 13 is a control circuit for the eccentric motor 14. The motor control circuit 13 operates the eccentric motor 14 and controls the rotation direction and the rotation time of the eccentric motor 14 based on the movement information received from the movement information detection circuit 12. . Therefore, the motor control circuit 13 corresponds to the control means.

  The eccentric motor 14 includes a motor main body 14a and an eccentric vibrator 14b. The eccentric vibrator 14b is a semi-cylindrical weight, and is attached to the rotating shaft 14c of the motor body 14a in an eccentric state. Thereby, when the rotating shaft 14c of the motor main body 14a rotates, the vibration force by a whirling will generate | occur | produce. When the communication terminal 10 is placed in a hard place such as on a desk, the communication terminal 10 moves in a certain direction by the vibration force. For example, when the rotation shaft 14 c of the eccentric motor 14 is rotated clockwise, a force Fcw in a certain direction along the rotation surface of the eccentric vibrator 14 b is applied to the communication terminal 10 due to vibration generated by the eccentric motor 14. For this reason, the communication terminal 10 tries to rotate around the center of gravity G. On the other hand, when the rotation shaft 14c of the eccentric motor 14 is rotated counterclockwise, a force Fccw in a direction opposite to the direction in which the force Fcw is applied is applied to the communication terminal 10. Therefore, the communication terminal 10 tries to rotate about the center of gravity G in the opposite direction to the case where the force Fcw is applied to the communication terminal 10. Actually, when the forces Fcw and Fccw are applied to the communication terminal 10, the communication terminal 10 rotates more accurately around the center of gravity G due to the frictional force between the communication terminal 10 and the desk surface. Perform both translational and rotational movements.

  An example of the control method of the communication terminal 10 will be described with reference to the time chart of FIG. In the time chart of FIG. 3, the horizontal axis indicates time, and the vertical axis indicates the rotation speed. The positive vertical axis indicates the direction A in FIG. 2, that is, the rotating shaft 14c rotates clockwise when viewed from the eccentric vibrator 14b side, and the negative vertical direction rotates when viewed from the eccentric vibrator 14b side. It shows that the shaft 14c rotates counterclockwise. In the example of the time chart of FIG. 3, the rotational speed of the eccentric motor 14 is constant both when rotating clockwise and when rotating counterclockwise.

  At time t1, when receiving a signal indicating an incoming call from an antenna circuit or the like, the motor control circuit 13 operates the eccentric motor 14 to rotate, for example, the rotating shaft 14c of the eccentric motor 14 clockwise. When the communication terminal 10 is placed on a desk, a force Fcw in a certain direction along the rotation surface of the eccentric vibrator 14b is applied to the communication terminal 10 by vibration generated by the eccentric motor 14 (see FIG. 2). . For this reason, the communication terminal 10 tries to rotate around the center of gravity G. Actually, as described above, both translational movement and rotational movement are performed. The translational movement amount and the rotational movement amount of the communication terminal 10 at this time are detected by the motion sensor 11 and the movement information detection circuit 12 and transmitted to the motor control circuit 13 as movement information.

  Next, the motor control circuit 13 causes the eccentric motor 14 to intermittently operate. Specifically, at time t2, the motor control circuit 13 stops the eccentric motor 14 once. At time t3, the motor control circuit 13 operates the eccentric motor 14 again. At this time, the motor control circuit 13 rotates the rotating shaft 14c of the eccentric motor 14 counterclockwise in order to return the communication terminal 10 to the position before the movement, that is, to return to the original position before the incoming call. A force Fccw in a direction opposite to the direction in which the load is applied is applied to the communication terminal 10. Here, the rotation time for rotating counterclockwise (hereinafter referred to as “reverse rotation time”), that is, the rotation time from time t3 to t4 in FIG. 3, is the movement information from the movement information detection circuit 12. It is controlled appropriately based on. Specifically, the motor control circuit 13 determines the reverse rotation time based on the translational movement amount and the rotational movement amount from time t1 to time t2. For example, the motor control circuit 13 holds a map in which the translational movement amount, the rotational movement amount, and the reverse rotation time are associated with each other in a memory or the like, and based on the translational movement amount and the rotational movement amount from time t1 to t2. The reverse rotation time is determined using the map. Here, the map is created in advance as an appropriate value by experiment or the like.

  Here, looking at FIG. 3, the rotation time for rotating the rotation shaft 14c of the eccentric motor 14 clockwise (rotation time from time t1 to t2) and the reverse rotation for rotating the rotation shaft 14c counterclockwise. It can be seen that it is different from the time (rotation time from time t3 to t4). This is because the amount of movement differs between the case of clockwise rotation and the case of counterclockwise rotation even when they are vibrated at the same rotational speed for the same time. The reason why the movement amounts are different is that the eccentric vibrator 14b is located at the end of the communication terminal 10 and the superposition balance is not symmetric with respect to the direction along the rotation axis 14c of the eccentric motor 14. Therefore, in the example shown in FIG. 3, the rotation shaft 14 c is rotated counterclockwise in order to return the communication terminal 10 to the original position as compared with the rotation time for rotating the rotation shaft 14 c of the eccentric motor 14 clockwise. The reverse rotation time to be made is longer.

  Thereafter, the motor control circuit 13 causes the eccentric motor 14 to perform an intermittent operation. Specifically, the motor control circuit 13 once stops the eccentric motor 14 at time t4, and then operates the eccentric motor 14 again at time t5. At this time, the motor control circuit 13 again rotates the rotating shaft 14c of the eccentric motor 14 clockwise.

  By repeatedly performing the control from time t1 to time t5 described above, even if the vibration function is activated and the communication terminal 10 is moved by vibration, for example, due to an incoming call, the range of movement is slightly within a certain range. The movement can be stopped and the communication terminal 10 can be prevented from falling from the desk.

  As can be seen from the above description, according to the first embodiment, when the movement of the communication terminal due to vibration is detected by the motion sensor, the eccentric motor is moved in the direction opposite to the direction in which it has been rotated. The rotating shaft is rotated. In the first embodiment, since the movement of the communication terminal is detected by the motion sensor, it is possible to reliably detect the movement of the communication terminal as compared with the method of determining the movement of the communication terminal according to the vibration amount of the communication terminal. it can. According to the first embodiment, the reverse rotation time for rotating the rotation shaft of the eccentric motor in the reverse direction is determined according to movement information such as the translation movement amount and the rotation movement amount of the communication terminal. In this way, even if the vibration function is activated and the communication terminal 10 is moved by vibration, the range of movement can be kept to a slight movement within a certain range. It can prevent falling.

[Second Embodiment]
Next, the communication terminal 10a according to the second embodiment will be described. Since the external configuration of the communication terminal 10a according to the second embodiment is the same as that of the communication terminal 10 according to the first embodiment, description thereof is omitted.

  FIG. 4 is an example of a diagram illustrating an internal configuration of the communication terminal 10a according to the second embodiment.

  As shown in FIG. 4, similarly to the communication terminal 10 according to the first embodiment, the communication terminal 10a according to the second embodiment includes a motion sensor 11, a movement information detection circuit 12, a motor control circuit 13, and an eccentric motor. 14. Since the function of each component is the same as that described in the first embodiment, the description thereof is omitted.

  In the communication terminal 10a according to the second embodiment, unlike the communication terminal 10 according to the first embodiment, the rotational surface of the eccentric vibrator 14b is positioned along a straight line L connecting the rotation center of the eccentric vibrator 14b and the center of gravity G. It is set to be. More specifically, the eccentric motor 14 is installed so that the angle formed by the rotation surface of the eccentric vibrator 14b and the straight line L is within the range of −5 ° to + 5 °. By doing in this way, compared with 1st Embodiment, it becomes easy to control the movement by the vibration of a communication terminal. For example, when the rotation shaft 14c of the eccentric motor 14 is rotated clockwise, a force Fcw in a certain direction is applied to the communication terminal 10a by vibration generated by the eccentric motor 14, and the communication terminal 10a is translated in a direction in which the force Fcw is applied. On the other hand, when the rotation shaft of the eccentric motor 14 is rotated counterclockwise, a force Fccw in a direction opposite to the direction in which the force Fcw is applied is applied to the communication terminal 10a, and the communication terminal 10a is translated in the direction in which the force Fccw is applied. That is, the communication terminal 10a according to the second embodiment does not need to consider the rotational movement with respect to the center of gravity G. This is because the center of gravity G is located on the straight line L along the direction in which the forces Fcw and Fccw due to the vibration generated by the eccentric motor 14 are applied.

  Similarly to the communication terminal 10 according to the first embodiment, when the movement of the communication terminal 10a is detected by the motion sensor 11 with respect to the communication terminal 10a according to the second embodiment, Rotates the motor in the opposite direction.

  An example of the control method of the communication terminal 10a will be described with reference to the time chart of FIG. In the time chart of FIG. 5, the horizontal axis indicates time, and the vertical axis indicates the rotational speed. The positive vertical axis indicates that the rotation shaft 14c of the eccentric motor 14 rotates clockwise as viewed from the eccentric vibrator 14b side, and the negative vertical direction indicates the rotation of the eccentric motor 14 as viewed from the eccentric vibrator 14b side. It shows that the shaft 14c rotates counterclockwise. In the example of the time chart of FIG. 5 as well, it is assumed that the rotational speed of the eccentric motor 14 is constant both when rotating clockwise and when rotating counterclockwise.

  At time ta1, for example, when receiving a signal indicating an incoming call from an antenna circuit or the like, the motor control circuit 13 rotates the rotating shaft of the eccentric motor 14 clockwise. For example, when the communication terminal 10 is placed on a desk, a force Fcw in a certain direction is applied to the communication terminal 10a by the vibration generated by the eccentric motor 14, and the communication terminal 10a is translated in the direction in which the force Fcw is applied. To do. The translational movement amount of the communication terminal 10a at this time is detected by the motion sensor 11 and the movement information detection circuit 12, and is transmitted to the motor control circuit 13 as movement information.

  Next, the motor control circuit 13 causes the eccentric motor 14 to intermittently operate. Specifically, at time ta2, the motor control circuit 13 stops the eccentric motor 14 once. At time ta3, the motor control circuit 13 operates the eccentric motor 14 again. At this time, the motor control circuit 13 rotates the rotating shaft 14c of the eccentric motor 14 counterclockwise in order to return the communication terminal 10a to the original position before the incoming call, and the force Fccw in the direction opposite to the direction in which the force Fcw is applied. Is applied to the communication terminal 10a. Here, as described in the first embodiment, the reverse rotation time (rotation time from time ta3 to time ta4) for rotating the rotation shaft of the eccentric motor 14 counterclockwise is from the movement information detection circuit 12. Appropriately controlled based on movement information. For example, the motor control circuit 13 determines the reverse rotation time using a map based on the translational movement amount from time ta1 to ta2. In this way, as described in the first embodiment, the counterclockwise rotation and the counterclockwise rotation caused by the difference in the superposition balance with respect to the direction along the rotation axis 14c of the eccentric motor 14 are used. The difference in the amount of movement in the case of the rotation of is corrected.

  Thereafter, the motor control circuit 13 causes the eccentric motor 14 to perform an intermittent operation. Specifically, the motor control circuit 13 once stops the eccentric motor 14 at time ta4, and then operates the eccentric motor 14 again at time ta5. At this time, the motor control circuit 13 again rotates the rotating shaft 14c of the eccentric motor 14 clockwise.

  By repeatedly performing the control from the time ta1 to ta5 described above, even if the vibration function is activated by, for example, an incoming call and the communication terminal 10a is moved by vibration, the movement always remains within a certain range. The communication terminal 10a can be prevented from falling from the desk.

  In the second embodiment, the eccentric motor 14 is arranged at the position shown in FIG. 4, but the present invention is not limited to this. In short, as long as the rotational surface of the eccentric vibrator 14b is positioned along the straight line L connecting the rotational center of the eccentric vibrator 14b and the center of gravity G, the rotational movement amount need not be considered. Therefore, for example, even if the eccentric motor 14 is arranged at any one of the positions p1 to p4 shown in FIG. 6, it is not necessary to consider the rotational movement amount.

  As can be seen from the above description, according to the second embodiment, the rotation surface of the eccentric vibrator is located along a straight line connecting the rotation center and the center of gravity of the eccentric vibrator. By doing so, it is only necessary to consider the translational movement amount as the movement information of the communication terminal, and it is not necessary to consider the rotational movement amount. That is, according to the second embodiment, control of the communication terminal can be simplified.

[Modification]
The embodiments are not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit or concept of the invention that can be read from the claims and the entire specification.

  In each of the above-described embodiments, it is assumed that the reverse rotation time of the eccentric motor 14 is controlled, and the rotational speed of the eccentric motor 14 is constant, but is not limited thereto. It goes without saying that the rotational speed of the eccentric motor 14 may be controlled instead of or in addition to this. For example, in order to shorten the reverse rotation time as much as possible, the motor control circuit 13 rotates the rotation shaft of the eccentric motor 14 counterclockwise as compared with the rotation speed when the rotation shaft of the eccentric motor 14 is rotated clockwise. It is also possible to set the number of rotations when rotated to a high value.

  In each of the above-described embodiments, the reverse rotation time is obtained using a map based on the amount of movement when the rotation shaft 14c of the eccentric motor 14 is rotated clockwise. However, the present invention is not limited to this. Absent. Instead of this, movement when the rotation of the eccentric motor 14 is controlled to return to the original position before the incoming call (in the above-described embodiments, when the rotation shaft 14c is rotated counterclockwise) A return amount that is a quantity may be obtained, and the eccentric motor 14 may be controlled based on the return amount. In the example of each embodiment described above, the motor control circuit 13 acquires the return amount from the movement information detection circuit 12 at regular intervals when rotating the rotating shaft 14c of the eccentric motor 14 counterclockwise. The motor control circuit 13 controls the rotation time and the rotation speed of the eccentric motor 14 based on the acquired return amount. For example, when the motor control circuit 13 compares the movement amount when the rotating shaft 14c of the eccentric motor 14 is rotated clockwise with the above return amount, and determines that the return of the communication terminals 10 and 10a is bad To increase the rotation speed. According to this, compared with the method using the map, the communication terminal is surely returned to the original position before the incoming call regardless of the state of the desk surface, that is, the fluctuation of the frictional force between the desk surface and the communication terminal. It becomes possible to return.

  In the above-described embodiments, first, the rotating shaft 14c of the eccentric motor 14 is rotated clockwise, and the rotating shaft 14c of the eccentric motor 14 is rotated counterclockwise based on the amount of movement at that time. However, it is not limited to this. Instead of doing this, first, the rotating shaft 14c of the eccentric motor 14 may be rotated counterclockwise, and the rotating shaft 14c of the eccentric motor 14 may be rotated clockwise based on the amount of movement at that time. Needless to say.

  Further, in each of the above-described embodiments, the case where the eccentric motor 14 is operated is exemplified as an incoming call, but the present invention is not limited to this. For example, in a communication terminal with an alarm clock function or a schedule management function, when the vibration function is turned on, the eccentric motor operates when a preset time is reached. Therefore, it goes without saying that the control method according to each of the above-described embodiments can be applied even when the eccentric motor operates in such a scene.

  Further, in each of the above-described embodiments, the eccentric motor 14 is controlled so that the communication terminals 10 and 10a move in the direction opposite to the direction of the movement on the assumption that the eccentric motor 14 moves due to vibration. However, the present invention is not limited to this, and the movement due to the vibration of the eccentric motor may not be assumed. That is, when the motion sensor detects that the communication terminal has moved due to some external force, the eccentric motor may be controlled so that the communication terminal moves in a direction opposite to the movement direction. In this case, since the rotation direction of the rotation shaft of the eccentric motor is determined according to the movement direction of the communication terminal, the movement information includes the movement direction in addition to the movement amount.

  Further, in each of the above-described embodiments, the communication terminals 10 and 10 a include the motion sensor 11, the movement information detection circuit 12, and the motor control circuit 13. Here, in recent years, communication terminals having a pedometer function and a navigation function have appeared, and such communication terminals are preliminarily provided with a motion sensor such as an acceleration sensor. In many cases, communication terminals collectively control various devices such as motion sensors and motors using a CPU (Central Processing Unit). Therefore, in such a communication terminal, it is possible to realize the communication terminal according to each of the above-described embodiments by executing the control program describing the control processing according to each of the above-described embodiments on the CPU.

  Furthermore, in each of the above-described embodiments, the communication terminal with the vibration function is taken as an example, but the example to which the control method according to each embodiment can be applied is not limited thereto. That is, it is not limited to the communication terminal, and it goes without saying that the control method according to each embodiment can be applied to any electronic device with a vibration function.
