Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wireless communication device that notifies an incoming call by vibration.
[0002]
[Prior art]
A wireless communication device with a vibrator function that notifies an incoming call by vibration, such as a cellular phone, has a weight eccentrically attached to a rotating shaft of a motor such as a built-in DC motor, and if this motor is rotated at the time of incoming call, the weight is eccentric. The vibration based on this is transmitted to the entire communication device so as to notify the incoming call.
[0003]
[Problems to be solved by the invention]
However, the conventional vibrator function has a configuration in which the motor drive voltage is uniformly applied to the motor in accordance with a predetermined vibration pattern. Therefore, the amount of vibration (vibration pressure, motor rotation speed, vibration frequency, etc.) is fixed, and adjustment during manufacturing cannot be performed. FIG. 3 is a conventional (a) vibration pattern diagram and (b) motor drive voltage pattern diagram, in which the application of the drive voltage is uniformly turned on when the vibration is on.
[0004]
[Means for solving the problems]
In order to solve the above-described problems, the present invention provides an incoming call detection means, a vibration device including a motor having a time constant TM and a motor drive voltage supply unit, and a drive voltage divided by a time interval shorter than the time constant TM. A storage means for storing a plurality of ON / OFF patterns, and when an incoming call is detected by the incoming call detection means, one drive voltage ON / OFF pattern is selected from the plurality of drive voltage ON / OFF patterns stored by the storage means. And a control means for applying a driving voltage to the motor based on the selected driving voltage ON / OFF pattern to vibrate the vibration device .
[0005]
In addition, a key operation unit is provided, and the control unit selects one drive voltage ON / OFF pattern from the plurality of drive voltage ON / OFF patterns stored by the storage unit in response to an operation on the key operation unit. I did it.

DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described with reference to the drawings. FIG. 1 is a mobile phone showing an embodiment of the present invention, in which FIG. 1A is a mobile phone block diagram, and FIG. 1B is a block diagram showing a vibration drive unit 4. In the figure, 1 is an antenna, 2 is a wireless transmission / reception unit, 3 is a microprocessor (including an incoming call detection unit and a control unit), 4 is a vibration drive unit, 5 is a microphone, 6 is a speaker, 7 is a key operation unit, and 8 is A display unit 9 indicates a memory. The vibration drive unit 4 includes a motor drive voltage supply unit 10 and a DC motor 11 having a time constant TM. The DC motor 11 is rotated by the drive voltage of the motor drive voltage supply unit 10, but a plurality of drive voltage ON / OFF patterns are stored in the memory 9 and driven by one of the arbitrary drive voltage ON / OFF patterns. As a result, the amount of vibration (vibration pressure, motor speed, vibration frequency, etc.) can be varied arbitrarily. Therefore, the vibration amount can be adjusted at the time of manufacture, or the user can arbitrarily set the vibration amount. One of the plurality of drive voltage ON / OFF patterns is selected at the time of shipment so as to be selected by the microprocessor 3 when an incoming call is detected and notified to the motor drive voltage supply unit 10, but the setting can be changed by operating the key operation unit 7 after shipment. You may be able to do it.
[0007]
FIG. 2 shows an example of the drive voltage ON / OFF pattern of the motor drive voltage supply unit 10 for the DC motor 11. The motor drive time is divided into several sections smaller than the motor time constant TM, and the ON or OFF applied voltage is divided into this. Can be adjusted and varied without changing the vibration pattern by apparently varying the continuous applied voltage of the DC motor 11 while the motor is being driven.
[0008]
【The invention's effect】
As described above, according to the present invention, it is possible to change the motor driving voltage during motor driving, which has been conventionally only ON, to an arbitrary ON / OFF pattern with respect to incoming notification due to vibration of the wireless communication device. The vibration amount can be easily adjusted at the time of shipment without changing the vibration pattern, or can be made variable after shipment.
