Description

CONTROLLING METHOD OF VIBRATION MODE IN MOBILE}

The present invention relates to a vibration mode of a mobile communication device, and more particularly, to a vibration mode control method of a mobile communication device for gradually driving a vibration motor of the mobile communication device.

In general, a reception alarm of a mobile communication device (MOBILE) including a cellular phone (CELLULAR PHONE) or a pager (PAGER) is divided into an acoustic alarm using a piezo or an etiquette mode using a vibration motor, that is, a vibration mode.

The vibration force F of the motor provided in the vibration mode of the mobile communication device is proportional to the eccentricity and is proportional to the angular velocity, that is, the rotational force of the motor. This is expressed as an equation.

F: Vibration force

Ud: eccentric

ω: Angular velocity

Here, the eccentricity is proportional to the mass of the eccentric weight and the distance between the rotation axis and the eccentric weight, and the vibration force of the motor is variable according to the angular speed. Therefore, by controlling the angular velocity used in the vibration mode of the mobile communication device, the appropriate vibration is caused.

The mobile communication device controls the rotation period of the motor for generating the vibration force, which is expressed by Equation 2 below.

That is, the vibration force of the motor is determined by the rotation period of the motor, and this rotation period is to be controlled by the amount of current supplied to the motor. The mobile communication device currently used is set the amount of current supplied to the motor, from which the vibration force felt by the user when switching the vibration mode is already set.

Therefore, since the vibration force obtained from the mobile communication device is initially set, the user may feel a sudden vibration during use, which may cause the user to obtain discomfort.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a vibration mode control method of a mobile communication device to automatically adjust the vibration amount of the vibration motor.

Vibration mode control method of a mobile communication device according to an aspect of the present invention for achieving the above object, a) for calculating the angular velocity of the motor based on the current ig value, the current ig value corresponding to the vibration force Fg of the motor The proportionality constant K, the ramped current amount delta i and the initial current amount i are set; b) requesting the user to set the vibration force Fg of the motor; b) requesting the user to set A or B mode; And c) when set to the B mode, adds the initial current amount i and the added and decreased current amount delta i, until the driving current F of the motor based on the addition result is equal to the driving force Fg of the motor. The motor is continuously added to drive the motor, and when set to the A mode, driving the motor with a current ig value corresponding to the vibration force Fg of the motor.

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>

Initial current amount i value, acceleration / deceleration amount delta i value, proportional constant K value according to the relationship between the angular velocity of the motor 111 and the input current to drive the vibration of the motor 111 to perform the vibration mode function of the mobile communication device Initialize a plurality of control programs according to the system operation, including a (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 initial current amount i value provided to the motor 111, and the amount of added and decreased current. The delta i value is stored.

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, for example, any one of small, medium, and large, the current ig is supplied to the motor 111 accordingly. The deceleration current amount delta i is an amount of current to be added to the current ig value according to a user mode selection, and is an addition value for gradually strengthening 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, the user sets the vibration force Fg (S203), and sets whether to use the vibration mode, that is, the gradual vibration mode, or to set the vibration value set by the user (S205). When the user intends to use the progressive vibration mode, the microcomputer 103 reads the initial current amount i value and the added or decreased current amount delta i value from the memory 105 and adds them to each other (S207).

The added result is supplied to the D / A converter 109 (S209), and converted into an analog signal and output (S211). Therefore, the motor 111 is rotated according to the analog output signal (S213). At this time, the microcomputer 103 determines whether the current amount supplied to the motor 111, that is, the vibration force F is equal to the vibration force Fg of the motor set by the user (S215).

As a result of determination, if the F and Fg are not the same (S221), and has a predetermined delay time (S221), fed back to the S207 is added to the added current value delta i to increase the amount of current supplied to the motor 111 Let's do it. When it is determined that F and Fg are the same by continually repeating the above process, it is determined whether the driving time of the vibration motor has been reached in the vibration mode of the mobile communication device (S217).

As a result determined in S217, when the driving time of the motor has not been reached, the motor 111 is driven by maintaining the current amount supplied to the motor 111. At this time, the acceleration / deceleration amount delta i is switched to zero and the motor The amount of supply current to 111 is maintained. When the driving time of the motor is reached, the flow of one side of the present invention ends.

On the other hand, when the user sets to the A mode in S205 to calculate the ig value corresponding to the vibration force Fg of the motor already set to replace it with the initial current i value (S223), the acceleration and current amount delta i to zero It is set (S225). The ig value may be calculated based on Equation 3, i.e., a linear result value may be used. However, in the present invention, a plurality of specific values of ig values calculated based on the equation are selected and the memory 105 is selected. An example is the storage in.

Therefore, the memory 105 selects and stores a plurality of ig values corresponding to linearly varying Fg values, thereby outputting already stored ig values according to the Fg values input from the user.

On the other hand, when the user sets the data corresponding to the vibration force Fg of the motor, it is set as a percentage of the maximum amount of current according to the driving of the motor, 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, the user inputs a percentage of 70 mA through the key panel 101 when setting the vibration force Fg of the motor 111. That is, inputting '70' to the key panel 101 indicates 70% of 70 mA, and 49 mA is supplied to the motor 111.

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 the amount of current supplied to the motor 111. ig is added or subtracted to a certain size. That is, when dividing the Fg value into small, medium, and small, the ig value corresponding to the Fg value divided by size is stored, and the user selects the Fg value step by step to select the vibration force Fg through one key. It can be.

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.

As described above, the vibration mode control method of the mobile communication device according to the present invention, as the vibration force generated in the vibration mode of the mobile communication device is gradually weighted to be transmitted to the user, due to the sudden operation of the vibration mode It is effective in removing the discomfort in use.

Anyone with knowledge of the world can make many variations.
