Problems that cause damage to the user or surroundings may occur. For example, when a call is received on a mobile terminal, the user may miss an important call because the user does not recognize the ringing tone or vibration due to the user's violent movement or walking, or is noisy than necessary in a conference hall or public place. The ringing tone or vibration may cause damage not only to the user but also to the surroundings.

Accordingly, the present invention provides a method and apparatus for adjusting a ringing tone or vibration intensity of a mobile terminal according to the degree of movement of a user.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

1 is a block diagram of a portable terminal according to the present invention. Hereinafter, the operation of the present invention will be described with reference to FIG. 1.

The controller 100 controls the overall operation of the mobile terminal, and in particular, analyzes the data received from the sensor unit 106 in the present invention and determines the ring tone value or vibration value corresponding to the amount of change of movement measured by the sensor unit 106. Output to the sound processing unit 104 or the vibration generating unit 108. In this case, the ringing tone value or the vibration value is the ringing tone size or the vibration intensity output through the sound processor 104 or the vibration generating unit 108.

The sound processor 104 converts an electrical sound signal into an audible sound and outputs the audible sound. In particular, in the present invention, the ringing tone is output in a size corresponding to the ringing tone value input from the controller 100.

The sensor unit 106 includes an accelerometer sensor, a geomagnetic sensor, and a gyro sensor. The sensor unit 106 outputs motion change data generated according to the movement degree of the user of the portable terminal to the controller 100.

The vibration generating unit 108 generates vibration in response to an input of the control unit 100 when the mobile terminal is set to the vibration mode or the silent mode. In particular, in the present invention, the vibration is generated at an intensity corresponding to the vibration value input from the controller 100.

The key input unit 110 is composed of numeric keys (including * and # keys) for dialing and function keys for various functions. The key input unit 110 generates a key signal corresponding to a key pressed by the user and outputs it to the controller 100. . The memory unit 112 stores data or various programs necessary for controlling the mobile terminal. The display unit 114 displays the current state of the portable terminal and the operating state of the portable terminal under the control of the controller 110.

2 is a block diagram of the sensor unit 106 according to the present invention. Hereinafter, the sensor unit 106 of the present invention will be described in detail with reference to FIG. 2.

The sensor unit 106 may include an acceleration sensor 202, a geomagnetic sensor 204, and a gyro sensor 206, and may include other sensors capable of sensing the movement of the mobile terminal.

The acceleration sensor 202 detects the acceleration of the portable terminal, the geomagnetic sensor 204 recognizes the movement direction of the portable terminal, and the gyro sensor 206 is an inclination (angle) generated by the movement of the portable terminal. Measure Such sensors are generally referred to as motion detection sensors because they can measure a user's movement. Here, the motion acceleration, the movement direction, or the inclination value of the mobile terminal measured by the sensor unit 106 is considered to be the same as the movement acceleration, the movement direction, or the inclination of the user possessing the mobile terminal.

When the incoming notification mode of the portable terminal is the vibration mode, the acceleration sensor 202 measures the movement of the user and the vibration generated by the motor in the portable terminal. A low pass filter (LPF) is provided between the acceleration sensor 202 and the controller 100 to calculate only a movement of a user (mobile terminal) except for vibration generated by a motor in the portable terminal.

The frequency corresponding to the vibration generated by the motor in the portable terminal is higher frequency than the frequency corresponding to the movement of the user. Therefore, the present invention attenuates the frequency caused by the vibration of the motor in the mobile terminal by passing only the frequency corresponding to the user's movement with the low pass filter (LPF). At this time, the cut-off frequency of the LPF is set to be smaller than the lowest frequency of the vibration generated in the vibration generating unit 108 and higher than the frequency generated by the violent movement of the general user.

3 is a control flowchart of using an incoming call intensity control function according to an exemplary embodiment of the present invention. After the incoming call intensity control function of the mobile terminal is set to be used by the user, the control flow when the call is received in the mobile terminal is described in detail below with reference to FIGS. 1 and 3. do.

In step 300, the standby mode before the incoming call is input, and all functions of the mobile terminal other than the call mode are available. In step 302, the control unit 100 proceeds to step 304 when the incoming call is input. If the incoming call is not input, the control unit 100 proceeds to step 300 to wait for input of the incoming call.

Proceeding to step 304, the control unit 100 receives the movement change amount data of the user measured at regular intervals, and determines the ringing tone value and / or the vibration value using the acceleration data which is one of the movement change amount data. The motion variation data is data measured by the sensor unit 106 corresponding to the degree of movement of the user, and includes movement acceleration or / and direction of movement and / or inclination of the mobile terminal. The ringing tone value is a ringing tone size and the vibration. The value is vibration intensity.

The step 304 of determining the ringing tone value and / or vibration value using the acceleration data calculates the sum of the acceleration or the acceleration change amount according to whether or not the exact zero point of the acceleration sensor is known and corresponds to the calculated value. Determine ring tone values and / or vibration values. That is, when the control unit 100 knows the exact zero point of the acceleration sensor 202 through sensor correction, the control unit 100 calculates the acceleration sum using the acceleration data input from the sensor unit 106 and the control unit. If the temporary 100 does not know the exact zero of the acceleration sensor 202, the acceleration change amount (jerk term) is calculated using the acceleration data input from the sensor unit 106.

The step 304 of determining the ring tone value and / or vibration value using the acceleration data will be described in detail later.

In step 306, the controller 100 determines whether the incoming call notification mode set by the user is a vibration mode or a ringtone mode.

       When the incoming notification mode is the vibration mode, in step 308, the control unit 100 transmits the vibration value determined in step 304 to the vibration generating unit 108, and the mobile terminal has a vibration intensity corresponding to the vibration value. Command the motor to run.

If the call notification mode is not the vibration mode, that is, in the ring mode, in step 310, the control unit 100 transmits the ring tone value determined in step 304 to the sound processor 104 to correspond to the ring tone value. Command to output the ring tone.

In step 312, when the controller 100 detects a call reception confirmation signal input by a user's key operation, the control unit 100 proceeds to step 314 to stop the call reception notification and perform a call mode. In this case, the call reception confirmation signal is a signal for notifying the mobile terminal that the user recognizes the call reception and will perform a call with the current destination, and may be generated by inputting a key operation or a preset voice during the call reception notification.

However, if the control unit 100 does not receive the call reception confirmation signal, the process proceeds to step 304 and repeats the above steps until the call reception confirmation signal is input.

The step 304 of determining the ring tone value and / or vibration value using the acceleration data will now be described in detail.

When the control unit 100 knows the exact zero of the acceleration sensor 202, the control unit 100 calculates the acceleration sum using the acceleration data input from the sensor unit 106. In this case, when the acceleration sensor 202 is three axes, the sum of the accelerations is calculated by the square root of each data of the x-axis, y-axis, and z-axis, and the user's motion is stopped in a state where the movement is large. The higher the change, the greater the sum of the accelerations. For example, the sum of accelerations when a person walks is generally calculated as 1g, and the stationary state is calculated as 0g.

When the controller 100 does not know the exact zero of the acceleration sensor 202, the controller 100 calculates an acceleration change amount (jerk term) using the acceleration data input from the sensor unit 106.

4 is a graph illustrating an acceleration change amount calculated by the controller using the acceleration data. In the graph, the larger the amount of change in acceleration per unit time, the larger the output of the ring tone size and / or the vibration intensity corresponding to the ring tone value and / or the vibration value.

The range of the acceleration sum and the acceleration change amount is provided as a predetermined value, and the ringing tone value and the vibration value corresponding to the acceleration sum and the acceleration change amount are also stored as a predetermined value.

The controller 100 determines a ringing tone value and a vibration value corresponding to each value when the sum of accelerations and the acceleration change amount calculated using the acceleration data are within the range.

In the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. For example, an incoming call can be reported by selecting one of the ring tone and vibration, but the incoming call can be notified by considering both the ring tone and the vibration. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be determined not only by the claims but also by the equivalents of the claims.

As described above, according to the present invention, the size of the ringing tone and / or vibration intensity of the mobile terminal can be adjusted according to the degree of movement of the user, thereby reducing the case in which the user does not recognize the incoming call due to the movement beyond the reference level.
