It can be set.

2. Description of the Related Art Conventionally, a means for arbitrarily setting the frequency and amplitude of vibration is described in JP-A-8-149182, and a means for changing the vibration with time is disclosed in JP-A-9-130840. Are known. 12 and 13 show circuit diagrams of a conventional vibration notifying device. In the conventional example 1 shown in FIG. 12, the motor 1 is provided with vibration generating means (not shown) such as an eccentric weight and the like, and the vibration is generated by the rotation of the motor. Battery 2 is a secondary battery such as a lithium ion battery. The transistor 101 and the transistor 102 and the resistor 201 are connected between the battery 2 and the motor 1, and the magnitude of the vibration can be selected by connecting the selection terminal 301 or 302 to the negative voltage of the battery.

In the second conventional example shown in FIG. 13, a portion corresponding to the resistor 201 of the first conventional example is an electronic volume whose resistance can be changed by a signal of a rotation speed setting terminal 303, and is connected in series to the motor 1. A method is disclosed in which the magnitude of the vibration is temporally changed by freely changing the magnitude of the connected resistor in accordance with the signal of the rotation speed setting terminal 303.

[0003]

These conventional methods are intended to improve the usability of the owner by selecting vibrations which are easily perceived or by gradually increasing the vibrations. However, in the case of small motors used in recent miniaturized and lightweight equipment, the variation in the characteristics of the motor itself to reduce the size and weight and the failure in starting due to the decrease in starting torque, etc. Attention has been paid to problems related to manufacturing variations and reliability. However, in the conventional method, not only these problems are not taken into consideration, but also the probability of starting failure tends to increase by connecting a large resistor between the motor 1 and the battery 2 to operate with small vibration. .

Further, since the vibration notification device is mainly incorporated in portable equipment such as a mobile phone, a secondary battery is often used as a power source. However, taking a lithium ion battery as a typical secondary battery as an example, the output voltage in actual use varies greatly from an output voltage of 4.1 V in a fully charged state to an output voltage of 3.3 V in a state near the end of discharge. For,
The rotation speed of the motor driven by the battery also changes according to the output voltage of the battery. Therefore, there is a problem that the magnitude of the generated vibration also changes depending on the state of charge of the battery.

The direction of the current flowing through the winding 1500 wound around the rotor core 1200 that can freely rotate in the
01, 1302 and commutators 1401, 1402, 1403
The brush and the commutator are parts that make mechanical contact with each other. However, since the brush and the commutator are parts that make mechanical contact with each other, abrasion powder and electrochemical products are generated in the commutator slits 1405 and 1405.
It may accumulate between 406 and 1407 and short-circuit between commutators. At this time, if the series resistor 201 is inserted between the battery 2 and the motor, no voltage is applied to the motor, so that the start may fail.

SUMMARY OF THE INVENTION The present invention provides a vibration notification device (hereinafter, abbreviated as a vibration notification device) which is required to be reduced in size and weight. By reducing the probability of startup failure, the present invention realizes a highly reliable vibration notification device with little variation while improving the usability of the user.

Conventionally, since only the magnitude or frequency of the vibration is changed, the difference of the vibration that can be sensed by the user is limited to three stages of large, medium and small, and the amount of information that can be transmitted is limited. Had been. Therefore, when there is a notification due to vibration, it is necessary to check the response or the display device to check the event or the sender that caused the notification. Therefore, it was not possible to make full use of the advantages of the vibration-based notification device, which allows the user to know the call to the own device without noticing to others.

According to the present invention, by setting or selecting an intermittent period of vibration instead of the magnitude and frequency of vibration arbitrarily, a larger amount of information can be transmitted than conventional devices by vibration alone. Even without confirmation, it is possible to distinguish between callers or events that require immediate response and callers who do not want to respond on the spot. It is to improve.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to FIGS.
5 will be described.

(Embodiment 1) FIG. 1 is a block diagram showing a vibration notifying apparatus according to a first embodiment of the present invention. In FIG. 1, the motor 1 is provided with vibration generating means (not shown) such as an eccentric weight, and the motor 1 generates vibration by rotation. Battery 2 is a secondary battery such as a lithium ion battery. The power supply IC 400, which is a means for stabilizing the voltage of the battery, supplies a stabilized voltage to an electronic circuit of a device such as a mobile phone on which the vibration notification device is mounted. The converted voltage is output. This voltage is connected to the base of the NPN transistor 101, and the motor 1 is connected to the emitter. Transistor 1
The collector of 01 is connected to the positive side of the battery 2 via the resistor 201. This is a circuit called an emitter follower. If a voltage between the emitter and the collector that can operate the transistor 101 in the active region can be secured, the output terminal 401 is connected to the emitter regardless of a change in the voltage of the battery 2.
, A voltage between the base and the emitter of the transistor 101, which is about 0.7V lower than that of the transistor 101, is output to a stable voltage of about 1.6V, which is supplied to the motor. The resistor 201 has an effect of limiting the upper limit of the current flowing out of the battery 2, protecting the transistor 101 and the motor 1, reducing power consumption of the transistor 101, and reducing heat generation.

In the circuit having such a configuration, even if the voltage of the battery 2 changes from 4.1 V to 3.3 V, the voltage supplied to the motor is constant (approximately 1.6 V in the example of FIG. 1). The current can be supplied up to an upper limit limited by the resistor 201.

Therefore, even if abrasion powder and electrochemical products of the brush and the commutator accumulate between the slits of the commutator and short-circuit between the commutators, a voltage of about 1.6 V is supplied and In addition, since a current enough to burn off the deposit can be supplied, the probability of starting failure can be reduced. Furthermore, since the motor can be started even if more deposits accumulate than before, the life of the motor can be substantially extended.

(Embodiment 2) FIG. 2 is a block diagram of a vibration notifying apparatus according to a second embodiment of the present invention. Components having the same functions as those in FIG. In FIG. 2, an output terminal of a power supply IC 400, which is a means for stabilizing the voltage of a battery, is connected to a power supply terminal 501 of a microcomputer 500 that controls the operation of a device in which the vibration notification device of the present invention is incorporated, such as a mobile phone. . Therefore, the voltage output from output port 502 of microcomputer 500 is a stabilized voltage substantially equal to the voltage of power supply terminal 501. This voltage is divided by the resistors 202 and 203 and connected to the base of the transistor 101. The transistor 101 drives the motor 1 by an emitter follower connection. The diode 3 sets the output port 502 of the microcomputer to L level to turn off the transistor 101.
It works to limit the spike voltage that occurs at the moment it is made to occur.

With this configuration, not only can the voltage supplied to the motor 1 be kept constant irrespective of the state of charge of the battery 2, but also the motor can be reduced in size by adjusting the value of the resistor 202 or 203. It is possible to absorb the variation in the characteristics of the motor, which has been increased in order to reduce the size and weight.

(Embodiment 3) FIG. 3 is a block diagram of a vibration notifying device according to a third embodiment of the present invention. The block diagram shown in FIG. 2 includes transistors 102 and 103 and resistors 206 to 209. A resistor 204 or 205 can be connected in parallel with a resistor 203 constituting a voltage divider via a switch circuit. This switch circuit is connected to the output ports 503 and 504 of the microcomputer, and can be turned ON / OFF by setting.

Therefore, the operation of absorbing the variation of the motor by changing the voltage dividing ratio of the voltage divider shown in the second embodiment can be performed by using the flash memory connected to the microcomputer via the bus 4 without changing the resistor 202 or 203. Etc. can be implemented by data stored in the storage means. By performing the work of storing data in this storage means while checking the vibration actually generated from the motor,
The work of absorbing the variation of the motor can be performed in a short time.

If the data to be stored in the storage means is set as data that changes with time, and the vibration is set to gradually increase with time, a large vibration is suddenly generated and the user is not surprised. Can be Also, if several types of patterns can be set, the size and pattern of the vibration can be easily detected according to the surrounding conditions, and the pattern of the vibration can be assigned according to the caller. A caller can be detected without taking a call.

(Embodiment 4) FIG. 4 is a block diagram of a vibration notifying device according to a fourth embodiment of the present invention. In FIG. 4, the base of the transistor 101 is a protection resistor 202.
Is connected to a DA output port 505, which is a voltage generating means built in the microcomputer 500, through which the voltage supplied to the motor can be changed according to data stored in the external memory 600 in advance. At this time, the voltage supplied to the power supply terminal 501 of the microcomputer is 3.0 V,
If the resolution of the DA converter built in the microcomputer is 8 bits, a voltage of 0 to 2.3 V can be supplied to the motor with a resolution of 11 mV. Therefore, it is possible to more precisely correct the variation in the characteristics of the motor and to set the magnitude of the vibration and the pattern more finely.
Further, since the supply voltage of the motor can be set precisely, it is possible to correct a change in vibration due to a change with time.

(Embodiment 5) FIG. 5 is a block diagram of a vibration notifying device according to a fifth embodiment of the present invention. In FIG. 5, a PWM output port 506 serving as a pulse train generating means incorporated in the microcomputer 500 is provided with a filter circuit. Are connected to the resistor 202 and the capacitor 5 forming a voltage generating means. Since the voltage generated here is connected to the base of the transistor 101, the external memory 60
The voltage supplied to the motor can be changed by changing the duty ratio of the pulse train generated at the PWM output port 506 according to the data stored in advance at 0. The diagram shown as the voltage at point A and the point B in FIG.
6 shows how the pulse train output from 6 is converted to a DC voltage.

It goes without saying that the motor 1 can be directly driven by PWM by eliminating the capacitor 5.

When a motor is driven by the PWM output port 506, a higher resolution can be obtained than when the output of the DA converter is used, so that more precise correction and generation of a pattern can be performed.

(Embodiment 6) FIG. 6 is a time chart for explaining the operation of a vibration notifying device according to a sixth embodiment of the present invention. The operation of FIG. 6 will be described by taking as an example a case where a transistor is driven by the DA output port of the microcomputer shown in FIG. In FIG. 4, when the voltage output from the DA port of the microcomputer is expressed as VC, and the voltage applied to the motor is expressed as VM,
In the present invention, data is stored in an external memory in advance so that a temporal change in VC and VM and the number of revolutions of the motor at the time of starting the motor has a relationship as shown in FIG. Start the motor with the profile of.

An object of the present invention is to cause a failure in starting due to a reduction in the starting torque of a recent miniaturized and lightweight motor and a failure in starting due to a temporal change of a contact portion between a brush and a commutator of the motor. It is an object of the present invention to solve a problem that occurs when the motor is started, such as the occurrence of a motor. Therefore, the present invention uses the first voltage V1 which is higher than the second voltage V2 supplied at the time of steady operation at the time of starting the motor, as compared with the case where the rotation speed of the motor reaches the rotation speed corresponding to the second voltage V2. The motor is supplied for a short period of time t to reliably start the motor.

In general, the probability of occurrence of motor startup failure decreases as the voltage applied to the motor increases. However, if a voltage higher than the voltage required for steady operation is continuously applied to the motor, excessive vibration is generated, which not only gives the user discomfort, but also consumes batteries and shortens the life of the motor itself. Problems occur. For this reason, in the present invention, the first voltage higher than the second voltage V2 supplied during the normal operation is set.
The time t during which the voltage V1 is supplied is determined by the number of rotations of the motor
By supplying power for a shorter time than necessary to reach the steady-state rotation speed corresponding to the voltage V2, the motor can be reliably started without problems such as user discomfort or deterioration of motor life.

(Embodiment 7) FIG. 7 is a block diagram of a vibration notifying device according to a seventh embodiment of the present invention. In FIG. 7, parts having the same functions as those in FIG. Omitted.

Referring to FIG. 7, reference numeral 801 denotes a rotor having a multipolar magnetized magnet; 802, 803, and 804, stator coils of a motor, which are sequentially energized by output terminals 702, 703, and 704 of a motor control IC 700; A brushless motor 801 generates a rotational torque. FIG. 8 is an example of a block diagram of the motor control IC. In FIG. 8, the stator coil 80
The induced voltages generated at 2, 803, 804 are converted into square waves by comparators 721, 722, 723 and input to the timing generation circuit 731. The timing generation circuit 731 delays the rising edge and the falling edge of the square wave by an electrical angle of 30 degrees to generate a timing for starting energization, and supplies the timing signal to the phase switching circuit 732. The phase switching circuit 732 supplies the base current to the transistors 792, 793, 794 via the power amplifier 740 for a period of 120 electrical degrees, and the stator coils 802, 80
3 and 804 are sequentially energized at the timing generated by the timing generation circuit 731. The power amplifier 740 outputs the output signal of the error amplifier 780 to the transistors 792, 793, 79
4 can be controlled, and feedback control is performed so that the reference voltage 781 and the output voltage of the FV conversion circuit 770 and the applied voltage of the rotation speed setting terminal 701 are rotated at a balance. Here, the FV conversion circuit 770 includes transistors 792, 793, 7
During the period when 94 is off, the stator coils 802, 803, 8
This circuit converts the amplitude of the induced voltage generated in the circuit 04 into a voltage and outputs the voltage. The circuit converts the rotation speed of the motor into a voltage and forms a closed loop for feeding back to an error amplifier 780 for controlling the operating current of the motor. Therefore, the rotation speed of the motor can be controlled by the voltage applied to the rotation speed setting terminal 701.

The capacitor 6 includes the closed-loop phase compensation, oscillation circuit 710, starting circuit 711, current source 750,
The switch 751 and the resistor 761 are circuits used for starting the motor, but their description is omitted.

By applying a voltage determined by the voltage of the output port 502 of the microcomputer 500 and the ratio of the resistors 202 and 203 to the rotation speed setting terminal 701 of the motor control IC 700, the speed is controlled irrespective of the charge state of the battery. The motor can be rotated at the rotation speed. Also, by using a brushless motor, not only can the motor be reduced in size by eliminating the need for brushes and commutators, but also it becomes easier to manufacture extra-fine and flat-type motors, which are difficult for motors with brushes and commutators. Therefore, the degree of freedom in designing equipment incorporating the vibration notification device is greatly expanded. In addition, since the motor speed is feedback-controlled, it is possible to stably rotate the motor at a low speed, which is difficult for motors with brushes and commutators. become. Furthermore, since there is no longer any restriction on the life and reliability caused by the brush and the commutator, a highly reliable vibration notification device can be realized.

(Embodiment 8) FIG. 9 is a block diagram of a vibration notifying device according to an eighth embodiment of the present invention. In FIG. 9, parts having the same functions as in FIGS. 3 and 7 are denoted by the same reference numerals. The description is omitted.

In FIG. 9, the rotation speed setting terminal 70 is provided by output ports 502, 503, and 504 of the microcomputer 500.
The fact that the rotation speed of the motor can be changed by changing the voltage applied to 1 is the same as in the case of FIG. 3, but it is difficult with a motor having a brush and a commutator because the rotation speed of the motor is feedback-controlled. Since the motor can be stably rotated even at a low rotation speed, the variable range of the vibration can be greatly expanded.

(Embodiment 9) FIG. 10 is a block diagram of a vibration notifying device according to a ninth embodiment of the present invention. Components having the same functions as those in FIGS. Omitted.

In FIG. 10, a rotation speed setting terminal 701 of the motor control IC 700 is connected to the DA output port 505 of the microcomputer 500, and can change the rotation speed of the motor according to data stored in the external memory 600 in advance. It has become. Therefore, the magnitude and pattern of the vibration can be set precisely and over a wide range.

FIG. 1 shows a block diagram of a vibration notification device according to FIG.
In FIG. 1, components having the same functions as those in FIGS. 5 and 7 are denoted by the same reference numerals, and description thereof is omitted.

In FIG. 11, the rotation speed setting terminal 701 of the motor control IC 700 is connected to the PMW of the microcomputer 500 via the resistor 202 and the capacitor 5 forming a filter circuit.
The output port 506 is connected to the external memory 600
By changing the duty cycle of the pulse train generated at the PWM output port 506 in accordance with the data stored in advance in the motor, the number of rotations of the motor can be changed. At this time, since the signal of the PWM output port 506 is used, higher resolution can be obtained as compared with the case of using the output of the above-mentioned DA converter, so that a more precise pattern can be generated.

(Embodiment 11) FIG. 15 shows a first embodiment of the present invention.
1 shows an example of a pattern of vibration generated by the microcomputer 1. In order to generate such a vibration, the apparatus shown in FIGS. 2 to 5 and FIGS. 7 and 9 to 11 is used. A signal whose intermittent cycle changes is generated, and the ON / OFF of the motor is controlled by the signal. According to the present invention, as is clear from FIG. 15, it is possible to easily determine a large amount of information only by vibration.

For example, if the intermittent pattern of the vibration is made to correspond to the Morse code, a short sentence can be transmitted only by the vibration.

(Embodiment 12) FIG. 16 shows a first embodiment of the present invention.
2 shows an example of allocation of a vibration pattern of a portable information terminal according to the second embodiment. When an event to be notified and a plurality of motor control data having different intermittent patterns corresponding to the event are assigned in advance as a correspondence table or a selection circuit, and an event to be notified such as a drop in battery voltage occurs, By warning the occurrence of an emergency in an intermittent pattern different from other events such as an alarm that notifies the arrival of the set time, the user can confirm the event that occurred on the display device etc. and prompt the user to respond promptly and reliably. Can be encouraged to respond.

(Embodiment 13) FIG. 17 shows a first embodiment of the present invention.
3 is a block diagram of a mobile phone according to No. 3; 17, components having the same functions as those in FIG. 4 are denoted by the same reference numerals, and description thereof is omitted. In FIG. 17, the rewritable external memory 600 stores in advance motor control data having a plurality of intermittent patterns and a correspondence table between the control data and the caller number.

When the own device receives the call, the microcomputer 50
0 searches the correspondence table based on the received caller number,
The assigned motor control data is transmitted from the output port 502. FIG. 18 schematically shows the correspondence table. By properly setting the correspondence table, the receiver can distinguish a sender who needs immediate response from a sender who should not respond immediately without having to answer or check the display device.

(Embodiment 14) FIG. 19 shows a first embodiment of the present invention.
4 illustrates the operation of the mobile phone according to No. 4. When receiving a short message, vibration of an intermittent pattern different from calling for a call is generated,
When the short message is received, the user is reliably notified that the call is not a call requiring a response.

(Embodiment 15) FIG. 20 shows a first embodiment of the present invention.
5 shows the operation of the timepiece device according to FIG. Since an intermittent pattern vibration is generated for each set time, it is possible to determine which set time has arrived without checking the display device.

FIG. 21 shows an example of a repetitive notification operation called a snooze operation. Since the vibration pattern becomes intensified stepwise and the amplitude increases, the user can be reliably notified of the arrival of the set time.

These effects can be used more effectively if used in conjunction with a scheduler such as a portable information terminal or a portable telephone as well as a clock device.

[0061]

As described above, according to the present invention, in a vibration notifying device used for a cellular phone, an information terminal, a timepiece or the like, a variation in the magnitude of the vibration caused by a variation in the characteristics of the motor is precisely corrected. Things, the magnitude of the vibration,
The pattern can be set finely. Further, there is obtained an advantageous effect that the probability of starting failure can be reduced and the change in vibration due to the change with time can be corrected.

Further, by setting or selecting the intermittent cycle of the vibration arbitrarily and changing the vibration pattern, a larger amount of information can be transmitted than the conventional apparatus only by the vibration, so that the response or the display device is not checked. However, since it is possible to distinguish between a caller or an event that requires an immediate response and a caller who should not respond immediately, the usability of the user can be greatly improved.

Further, by combining the magnitude of the vibration and the intermittent cycle, more information can be easily identified.

In this case, the vibration generating device is not limited to the motor, and the effect is not limited to a vibration device or a resonance device having a reciprocating vibrator, and the motor control data is not limited to the output port, but may be the DA output port or the PWM output. It goes without saying that the same effect can be obtained by using a port.
