The present invention relates to a portable terminal, such as a PDA (Personal Digital Assistance), a smart phone, a mobile phone, a portable Internet terminal, a portable multimedia terminal, an apparatus that informs a user that a specific event has occurred or moves the terminal for entertainment. And to a method.

In general, when a call is received from a mobile phone, a vibration, alarm, or lamp is activated to indicate that the call has been received. However, these methods are only extremely common methods, and there is a problem for users.

In a place requiring quietness, most users use the notification method as a vibration, but there is a problem that call reception cannot be known unless the user directly contacts the terminal. In particular, when the terminal is located in a hard place, such as a desk in the library, there is a problem in that the noise occurs to harm the learning environment.

On the other hand, toys such as general dolls are fixed to one side of the main body to the base and using a motor, etc. fixed to the base to cause the toy body to shake or move, but the terminal that is always carried without the base of the movement itself is popular It is not becoming. When the terminal is operated by vibration in the state mounted on the floor, the terminal moves finely, but recognition by noise rather than movement is a matter of course. The wheel may be used to move the mobile phone, but this is not only necessary for the function of the portable terminal, but also increases the manufacturing cost.

An object of the present invention to solve the above problems is to provide an apparatus and method that can move the terminal for visual recognition of the user.

According to an aspect of the present invention, there is provided a moving device of a portable terminal, comprising: moment means for generating a moment to cause shaking of the terminal in a left and right or front and rear directions when the terminal is mounted; Control means for outputting a control signal for generating the moment, characterized in that the bottom surface of the terminal in contact with the floor is a curved surface.

The portable terminal according to the present invention relates to an apparatus and a method for allowing a terminal to move when a call is received or listening to music while the terminal is mounted. The controller 10 of the portable terminal controls the overall operation of the terminal. According to the present invention, when an event such as a call is received, the vibration motor 14 operates by means of the moment so that the terminal can move back and forth or from side to side.

The key input unit 11 has a numeric key and a plurality of function keys.

The image processor 12 adjusts an operation of the display unit 13 according to a control signal of the controller 10, and converts and outputs display data according to the control signal.

The display unit 13 may be formed of an LCD or the like, and outputs display data under the control of the image processor 12.

The RF unit 15 demodulates and outputs a signal received through the antenna, modulates a signal input through the control unit 10, and transmits the signal through the antenna.

The memory unit 16 stores various data for operating the terminal, and stores data input through wired or wireless.

The voice processing unit 17 converts the voice data processed by the control unit 10 into an audible band and outputs it through the speaker, and digitally converts and outputs the voice input through the microphone.

Vibration motor 14 is a means for generating a moment for moving the terminal as shown in Figure 3 is a motor 22 is a mass eccentric weight 22 is coupled to. Of course, the moment means may be used, such as a vibrator using an electromagnet and a permanent magnet.

Energy flows from high to low. That is, the object moves in the direction of low potential energy against gravity. This means that the object is stable when its center of gravity is at a low position and moves in the direction to maintain that stability. 2 illustrates this principle. The position object of A (18) is an object in which the position 21 of the center of gravity is higher than that of B (19), but the position of the center of gravity (21) is the best in order to maintain a low energy state. The exercise is changed to a state of low B 19 to change the state. However, after changing from the state of A (18) to the state of B (19) as the potential energy is changed to the state of kinetic energy (B), the state of B (19) is moved to the state of C (20) by the remaining surplus kinetic energy. do. At this time, the air resistance and the friction force do not substantially change the state of C (20) at the same height as the state of A (18). The terminal moved to the state of C (20) in the opposite direction by the kinetic energy is to return to the state of B (19) in order to move the position energy in the lower direction is to move left and right.

The present invention is generated by the rotation of the weight 22 by using a motor 23, which will have a weight 22, the weight is built in the mobile phone based on the principle of the movement according to the change in the kinetic energy and potential energy By using the vibration effect, the terminal does not fall and performs left / right movement. To this end, an embodiment of the present invention implements a mobile phone having an ellipse or a circular locus as shown in FIG. 4 so that the mobile phone has left / right movement.

25 is the coordinate system in the table where the cell phone is located

(27),

Reference numeral 26 denotes a coordinate system fixed to the mobile phone. Where subscripts 1, 2, and 3 refer to the X, Y, and Z axes. Point G 21 represents the position of the center of gravity of the cellular phone, point P 34 represents the mounting position of the weight, and point A 28 represents a reference position defined to define the shape of the floor. In addition, x (33), y (31) is the position coordinate value to the shape reference point, a (29) means the attitude that the mobile phone is turned. The shape of the floor may have various shapes, and the shape may adjust various types of trajectories by changing the axes a 30 and b 31 using the trajectories of the ellipses.

With the bottom trace as axis a = 3cm (30) and axis b = 2cm (31), the movement of the mobile phone is shown in FIG. 5 when the mobile phone is tilted and released by 30 ° without vibration. If you look at the movement for 1 second when the bottom of the phone is elliptical, you can see -30 ~ +30 gap left / right oscillation box (Fig. 5a) and move -1.0cm ~ + 1.0cm in the X-axis direction about the reference point. 5B), it can be seen that 2.0 cm to 2.5 cm is moved in the Y-axis direction (FIG. 5C). Since the center of gravity of the mobile phone 21 is in a low position, it has stability, and it can be seen that the position energy and the kinetic energy change to move left / right to maintain the stability.

The movement of the unbalanced weight 22 built in the mobile phone acts on the mobile phone's center of gravity 21 after the mobile phone is placed in consideration of the position of the center of gravity 21 of the mobile phone and the mounting position 34 of the weight so that such movement occurs. Use the moment to do left / right movement. In general mobile phones, the antenna is installed at one side, and the printed circuit board inside is not designed to distribute the weight uniformly, so the standing state may be inclined to one side. Therefore, a separate mass unit may be added to make the mobile phone stand vertically in a normal standby state. By installing a mass unit such as iron piece on the other side of the inclined, it can be realized at any time standing vertically.

Figure 6 shows the result of implementing this principle using a vibration motor built into the mobile phone. Fig. 6 shows the mobile phone moving left / right at -10 ° to + 10 ° (Fig. 6A), showing a distance of -0.2cm to + 2.0cm movement in the X-axis direction (Fig. 6B). Figure 2c shows the movement of 2.0cm to 2.014cm. Compared with FIG. 5, the rotation angle is small but the moving pattern is the same. It can be seen that the bottom surface trajectory is circular or ellipse and by using the rotation of the built-in vibration motor 23 can move the mobile phone to the left / right.

Even in the same shape of a mobile phone, if the center of gravity 21 is different, each shows a different movement (see FIG. 7). According to the position of the center of gravity, the angle and the period (Fig. 7a) of moving the left / right are different, respectively, the distance moving in the X-axis, Y-axis direction of the point A (Fig. 7b, c) can be seen that different. Preferably, the center of gravity 21 is at the bottom as much as possible, and as the curved surface curvature a / b of the bottom of the mobile phone becomes smaller, the movement angle of the mobile phone becomes larger. Even if the center of gravity 21 is located at the bottom, if the curvature is large, the stable movement angle of the mobile phone becomes small.

The change in the rotational speed of the vibration motor 23 embedded in the mobile phone also brings about the change of the period of the left / right movement of the mobile phone and the moving angle and the moving distance in the X-axis and Y-axis directions (see FIGS. 8A, 8B, and 8C). . That is, the vibration motor having a rotating shaft embedded in the mobile phone has an uneven mass 22, so that the centrifugal force is generated by the rotation of the unbalanced rotating body during rotation, and the centrifugal force is the moment about the center of gravity of the mobile phone. The phone will move. Therefore, the change in the number of revolutions of the weight brings about a change in the moment acting on the mobile phone, resulting in a change in movement.

는 가속도)(도시안됨) 회전축을 기울여 놓는 것에 따라 각각의 움직임은 다르게 나 타난다. 바람직하게는 핸드폰이 움직이는 축방향(X)에 수직한 축에 회전축이 평행하도록 진동모터(14)를 설치하면, 회전방향에 따라 핸드폰의 움직임을 쉽게 제어할 수 있다. 예를들어 무게중심(21)에 진동모터(14)가 설치되되, 회전축이 Z축과 평행하도록 설치되면 진동모터가 시계방향으로 회전하면 휴대폰은 우측으로 기울게되고, 진동모터(14)가 반시계방향으로 회전하면 휴대폰이 좌측으로 기울어지게 된다. In addition, the movement of the mobile phone appears differently depending on the position of installing the vibration motor 23 on the coordinate axis of the mobile phone. Depending on whether the vibration motor is placed parallel to the Z-axis (Figure 9a), parallel to the X-axis (Figure 9b) or parallel to the Y-axis (Figure 9c), the movement of the mobile phone is different. To include the Z-axis component (

(Acceleration) (not shown) Each movement is different as you tilt the axis of rotation. Preferably, if the vibration motor 14 is installed so that the rotation axis is parallel to the axis perpendicular to the axial direction (X) the mobile phone, it is possible to easily control the movement of the mobile phone according to the rotation direction. For example, if the vibration motor 14 is installed in the center of gravity (21), if the rotating shaft is installed parallel to the Z-axis when the vibration motor rotates clockwise, the mobile phone is inclined to the right, the vibration motor 14 is counterclockwise Rotating in the direction will tilt your phone to the left.

When the axis of rotation of the vibration motor 14 is located parallel to the Y axis, the axis of rotation and the vertical axis passing through the center of gravity 21 do not have to coincide. When there is a rotating shaft of the vibration motor on the right side in comparison with the vertical axis passing through the center of gravity 21, the terminal is inclined to the right side when the direction of rotation is inward in the vertical axis direction. If there is a rotation axis of the vibration motor on the left side compared to the vertical axis passing through the center of gravity 21, the terminal is inclined to the left side when the direction of rotation is inward in the vertical axis direction.

At this time, the magnitude of the moment generated by the operation of the vibration motor 14 can be controlled by the rotational speed and the rotation time of the vibration motor (14). Therefore, the inclination angle can be adjusted by controlling the rotational speed or operating time of the vibration motor 14. On the other hand, the position of the vibration motor 14, the moment is generated is able to move the mobile phone with a small force when it is as far away from the center of gravity as possible. This is the same principle as the lever.

4 illustrates a state in which the terminal is inclined to the left side. When the center of gravity 21 is located on the right side of the terminal with the vertical axis from the contact point of the terminal, the terminal may be restored to the standby state without being conducted. If the angle of inclination toward the left side is exceeded and the center of gravity 21 is located on the left side inclined with respect to the axis perpendicular to the contact point, the terminal is inverted to the left side and does not return to the standby state.

Accordingly, the terminal may be restored again when the center of gravity 21 of the terminal, which is inclined toward one side, is located on the other side with respect to the vertical axis from the contact point. Therefore, the maximum movement angle is when the center of gravity 21 is located on the vertical axis from the contact point.

In the movement control, the vibration motor 14 is installed on the right side of the vertical axis passing through the center of gravity 21, and the rotation axis of the vibration motor 14 is installed vertically, and the rotation direction passes through the vertical axis passing through the center of gravity 21. Rotate to face and your phone will tilt to the right. Vibration motor 14 is installed on the left side of the vertical axis passing through the center of gravity (21), the rotation axis of the vibration motor 14 is installed vertically, if the rotation direction is rotated toward the vertical axis passing through the center of gravity (21) Will be tilted to the left.

The mobile phone is equipped with a weight (22) of uneven mass. The mobile phone is moved using the moment acting on the center of mass by the rotation of the unbalanced weight 22, and the force is different depending on the initial position of the weight. The initial position of the weight was varied by 30 °. It can be seen that the movement of the mobile phone is shown differently according to the change in the initial position (FIGS. 9A, 9B and 9C). Therefore, it can be seen that the movement angle can also be controlled by controlling the initial position of the weight. To this end, in order to control the initial position of the weight in the embodiment of the present invention, it is possible to control the position of the weight by installing a device that gives an electrical signal to the vibration motor 60 in accordance with the mechanical position change of the motor. Potential meters and rotary encoders provide electrical signals in proportion to mechanical position changes. Therefore, the movement angle can be controlled by using the arrangement position of the vibration device and the initial angle control of the weight.

Next, looking at the movement of the mobile phone through the change of the axis a (30) and the axis b (31) for determining the bottom surface trajectory of the mobile phone as follows. The axis b (31) of the mobile phone was fixed at 2 cm and the axis a (30) value was changed to examine the movement of the phone. (Figs. 10a, b, c) The length of the axis a (30) is 3.0 cm, 3.5 cm days. In this case, the mobile phone moves left and right as we saw earlier. When the length of the shaft a (30) to 2.5cm, the mobile phone has a tilting motion to one side, but it can be seen that the fall down without restoring in the opposite direction (Figs. 10A, 10B and 10C). Therefore, in order for the mobile phone to move left / right, the length of each axis must be made within a certain range. However, in the case where the falling motion is not restored in the opposite direction, the movement can be controlled by adjusting the rotation time of the vibration motor 23. In other words, by adjusting the rotation time of the vibration motor it is possible to prevent the fall of the mobile phone by stopping the rotation of the motor before falling to an unstable state. In this way, after grasping the movement characteristics of the mobile phone, it is possible to stabilize the movement of the mobile phone by rotating the vibration motor according to the characteristics.

As described above, the present invention installs a vibration motor that can generate a moment in the mobile phone round the bottom, when the call is received or an alarm is set, by operating the vibration motor when the event occurs, the user easily generates an event There is an advantage that can be sensed, and give a play function when listening to music or.
