Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating an apparatus for controlling a vibration mode of a mobile communication device according to the present invention. 2 is a flowchart of FIG. 1. First, a microcomputer 103, a memory 105, a timer 107, a D / A converter 109, a keypad 101, and a motor 111 are added to a mobile communication device, that is, a cellular phone, a PCS, a pager, or the like.

<Action description>

In order to perform the vibration mode function of the mobile communication device, the basic current amount i value for driving the vibration of the motor 111 and the proportional constant K value according to the relationship between the angular velocity of the motor 111 and the input current are included in the system operation. Initialize a plurality of control programs according to (S201).

The motor 111 performs a vibration function of the mobile communication device, and the memory 105 has an ig value corresponding to the vibration force Fg of the motor 111, an accelerating current amount delta i value smaller than the ig value, and a dynamic value set from the outside. / Save the date information corresponding to the summer.

Here ig is the amount of current provided to the motor 111 to generate the vibration force Fg. Therefore, when the vibration force Fg is set by the user is to supply the current ig to the motor 111 accordingly. The ramped current amount delta i is a current amount to be reduced to the ig in the summer, to weaken the vibration force. The memory 105 stores an ig value corresponding to the vibration force Fg value, which stores a plurality of sample values in a predetermined unit.

Such an ig value may be set by a calculated value, which may be determined by Equation 3 as an example.

m: weight of the eccentric weight

r: distance between rotation axis and eccentric weight

Therefore, when the user sets the vibration force Fg (S203), the ig is calculated (S205), in addition to generating an ig value by such a calculated value, in the present invention, calculated based on the above equation For example, a plurality of specific values of ig values are selected and stored in the memory 105. For example, when the vibration force Fg is divided into small, medium, and high, the ig value corresponding to the divided vibration force Fg is stored in the memory 105.

In addition, the set date information may be set to the winter season from September to the following year, and to the summer season from April to August of the next year, as well as to change the date information according to the region. Of course it can. On the other hand, the date information may be used by inputting necessary seasons other than winter and summer.

Therefore, winter and summer are distinguished based on the date data provided from the mobile communication device.

The timer 107 is for generating current date data, and the microcomputer 103 receives the vibration force Fg value and the date information of the motor 111 from the keypad 101. The user sets the vibration force Fg value in the vibration mode, and inputs date information for distinguishing winter and summer.

The microcomputer 103 reads current date data from the timer 107 (S207), and determines whether the date information corresponding to the date data, that is, winter season or summer season (S209). When the determined date information, for example, is determined to be winter, the ig value corresponding to the vibration force Fg value of the motor 111 is selected from the memory 105, and the corresponding data is converted into the D / A converter 109. Supply to (S213).

On the other hand, when the determined date information is summer (S211), the ig value is subtracted from the delta value i and the data corresponding to the subtracted ig value is output to the D / A converter 109. .

The D / A converter 109 converts data corresponding to ig transmitted from the microcomputer 103 into a current amount (S215), and supplies it to the motor 111 (S217).

Therefore, in winter, the ig value corresponding to the Fg value set by the user is supplied to the motor 111 to have a vibration force corresponding to the Fg, and in the summer, the delta value is added to the ig value corresponding to the Fg value set by the user. The vibration force is weakened by supplying the ig 'value obtained by subtracting the i value to the motor 111.

In setting the data corresponding to the vibration force Fg of the motor, the user sets the data as a percentage of the maximum current according to the driving of the motor, and the percentage is to use the key panel 101 of the mobile communication device. For example, when the amount of current supplied to the motor 111 is 70 mA, when the user sets the vibration force Fg of the motor 111, the user inputs a percentage of 70 mA through the key panel 101. That is, when '70' is input to the key panel 101, 70% of 70 mA is represented, and 49 mA is supplied to the motor 111.

Meanwhile, as another embodiment, the data setting corresponding to the vibration force Fg of the motor 111 may be adjusted step by step through one specific key provided in the mobile communication device, which is supplied to the motor 111. The amount of current ig to be added or subtracted to a certain size. Therefore, the user can select the vibration force Fg through one key.

Meanwhile, in the present invention, the vibration force of the motor is selected by the current ig value, but the vibration force of the motor can be changed through the voltage. For example, the vibration force of the motor is controlled through voltage control based on the following Equation 4 in the current ig, the motor resistance R and the driving voltage Vg of the motor.

Therefore, the driving voltage Vg of the motor is controlled based on the already set ig value and R value.

In addition, in the present invention, the mobile communication device can be applied to a cellular phone, a PCS or a pager.
