Abstract

PURPOSE: A vibration informing method of a mobile terminal is provided to reduce noise and power consumption caused by vibration by sequentially increasing the amount of vibration of a motor when announcing an incoming call. CONSTITUTION: A terminal detects a call incoming signal and determines a currently set informing mode. If the informing mode is not a stepwise vibration mode, the corresponding informing operation is performed. If the currently set mode is the stepwise vibration mode, a user receiving operation is checked during only pre-set driving time and a vibration motor is turned on/off. If a user receiving operation is detected, motor driving is stopped. If the user receiving operation is not detected until certain pre-set time elapses, the driving time is increased by stages until it reaches a maximum value.

Description

Vibration notification method of mobile device {VIBRATING NOTIFICATION METHOD FOR MOBILE TERMINAL}

The present invention relates to a vibration notification method of a mobile terminal, and in particular, in order to reduce the noise and power consumption due to vibration by increasing the amount of vibration of the motor sequentially during the reception guidance using the vibration motor in the reception guidance method of the mobile terminal. It relates to a vibration notification method of a portable terminal.

Typically, wireless terminals use vibrations or bells to alert users when a message is received or a call is made.

In the case of a bell, a plurality of bells are stored in a conventional manner so that a user of a wireless terminal can rapidly generate various ringing tones. In addition, it is possible to adjust the size of the ringtone in response to changes in the surrounding environment or user needs.

However, in the case of vibration notification, unlike the ring tone, the magnitude of the vibration cannot be adjusted, and the vibration is always set to the same value as the value set at the time of manufacture.

Thus, users who are sensitive to vibration often receive surprises when there is an incoming call, and when the terminal is placed on a hard object such as a desk, a large noise occurs. In addition, if the noise is not sensitive, there is a problem that the phone does not recognize that the vibration is not detected. In the above case, even when the terminal is placed in a thick cloth or in a place such as a bag in the vibration mode, it occurs randomly.

In addition, the use of vibration increases power consumption more significantly than when using a bell. Even vibration-sensitive users generate fixed vibrations with the same intensity and time, thereby wasting unnecessary power.

Therefore, various approaches have been proposed to solve this problem. The method of controlling the input voltage of the vibration device is mainly used.

Korean Patent, 10-1998-0060940, 'Variable Vibration Device of Wireless Terminal', discloses that the power supplied from the battery is separated into a number of different voltages using a DC / DC converter, and a constant voltage regulator at each output After adding, the selected power is applied to the vibration motor using the mux. This is applied to the motor by separating the voltage step by step, and it can adjust the vibration strength of the motor, and it has a function to set the desired vibration strength by the user, but the power consumption of DC / DC converter, regulator and mux is high and additional hardware There is a problem of cost increase due to mounting.

In addition, Korean Utility Model, 20-1998-001354, Utility Model entitled 'Vibration Intensity Control Circuit in Mobile Communication Terminal' also uses a multiplexer to change the driving voltage applied to the vibration motor. By using the method of applying the vibration of the desired intensity to the motor. Therefore, there is a problem that the cost increases because additional hardware changes and additions are required.

As described above, the conventional vibration notification method has a problem that the vibration motor operates uniformly for a fixed intensity and time, causing noise and power consumption. Since the fixed voltage is applied to the vibration motor, a user's setting needs to be changed according to the use, and since hardware for generating the voltage to be applied to the motor is added separately, cost and power consumption increase.

In view of the above problems, an object of the present invention is to provide a vibration notification method of a portable terminal for distributing vibration noise without adding hardware by controlling a driving voltage of a vibration motor in a time domain.

1 is a flow chart showing the sequence of an embodiment of the present invention.

The present invention for achieving the above object, the first step of the mobile terminal acquires the incoming call signal and confirms the set notification mode; A second step of performing a corresponding notification operation when the currently set notification mode is not the stepwise vibration mode; A third step of checking a user reception operation during a set driving time and a waiting time and turning on / off a vibration motor when the currently set notification mode is a stepwise vibration mode; When the user reception operation is detected in the third step, the motor driving is stopped and the vibration mode is terminated. If the user reception operation is not detected by the predetermined time, the driving time is increased step by step until the maximum value is reached. It characterized in that it comprises a fourth step of returning to.

The driving time set in the third step is a time for operating the motor, the standby time is a time for stopping the motor, and the set time of the fourth step is characterized in that the number of times driving the motor with the current driving and standby time.

The method for confirming the user reception operation in the third step is characterized in that the interrupt method is irrelevant to the performance of the stepwise vibration mode.

When described in detail with reference to the accompanying drawings an embodiment of the vibration notification method of the present invention portable terminal as follows.

1 is a flowchart illustrating a procedure of an embodiment of the present invention, in which a terminal detecting a incoming call signal, as illustrated, determines a current notification mode setting; Performing a corresponding notification operation when the notification mode is not the stepwise vibration mode; When the currently set step is a stepwise vibration mode, checking a user reception operation only for a set driving time and operating the vibration motor on / off; Stopping the motor driving when the user reception operation is detected in the above step, and increasing the driving time step by step until the maximum value is reached if the user reception operation is not detected by the predetermined time, and returning to the previous step. It is.

The stepwise vibration mode is a mode proposed by the present invention. When the predetermined driving time is n, the stepped vibration mode operates to stop the motor for a predetermined waiting time after driving the motor for the set driving time n. The waiting time is called t. Note that the reception operation by the user may use a polling method as in the flowchart, but may operate independently of the stepwise vibration mode using the interrupt method.

Since the reception operation by the user is detected and the vibration notification is stopped and the call is switched to the incoming mode, the call is not described in the following description.

The motor is driven for a predetermined time (n) and the operation is stopped for a predetermined waiting time (t) so as to recognize the user. The motor driving (n time operation, t time standby) as described above may be performed at a predetermined set time ( After repeating for D), the set time is increased step by step. The predetermined setting time D may mean the number of times of driving the motor. That is, assuming that the step increment time is a, the set time is n + a, and the waiting time t may be fixed or t-a. The driving time n cannot be greater than the maximum time N set at design time.

That is, referring to the order, first, the motor operates with the driving time n and the standby time t, and if the predetermined elapsed time D does not pass, the motor operates with the driving time n and the standby time t. When the predetermined elapsed time (D) has elapsed, increase the driving time to (n + a) and check that the value is not greater than N. At this time, if more than N is fixed to N. Then, the operation of driving the motor again with the newly set driving time is repeated.

Therefore, when the user sets the staged vibration mode, the mobile terminal detects an incoming call for the first time and vibrates for a short time, waits for a predetermined time, and then vibrates for a short time to make a call to the user in a relatively low noise generation method with less vibration intensity. If the user does not recognize this, the vibration time is gradually increased so that the user can detect it.

That is, when the user recognizes the incoming call during the initial driving of the terminal, the noise and the motor driving voltage consumption can be reduced.

By the manufacturer's choice, the present invention may be added to the current notification mode and may replace the vibration notification mode currently used.

Among the set times, the waiting time t or the number of driving D may be fixed. In addition, when the driving time reaches the maximum value N, the motor may be stopped and the reception impossible processing may be performed.

In the present invention, it is essential that the time (n) that the actual motor is driven gradually increases so that the user recognizes the incoming call in a state in which power consumption and noise are relatively low. Note that it can be fixed, changed, or deleted.

Therefore, the present invention can be realized by simple program addition without adding hardware or changing the configuration, thereby improving the use environment without increasing the cost. This not only provides a method of reducing power consumption while functionally improving a notification function to a user, and can effectively reduce a noise problem caused by a mobile terminal, which is a recent social problem.

As described above, the vibration notification method of the mobile terminal of the present invention gradually increases the vibration motor driving time so that the user recognizes it, thereby reducing the noise that may occur due to vibration when the user recognizes it at the initial reception and consumes power by driving the motor. There is an effect of suppressing, there is an effect of providing a means for suppressing the generation of noise due to the use of a mobile terminal to the maximum.
