The present invention relates to a device for automatically switching the bell / vibration mode of a mobile phone, and more particularly, to automatically detect and vibrate when a mobile phone (mobile phone) is being carried or not while being charged, as well as during long-term storage. The present invention relates to a device for automatically switching the bell / vibration mode of a mobile phone to automatically switch to a mode or a bell mode.

In general, mobile phones are designed to notify incoming calls by bells, vibrations, or flashing lamps.

However, such a conventional mobile phone has been set up to manually set the incoming method, so forget it in the state set to notify the incoming call ringtone, and carry it in public places such as subways, conference venues, cinemas, lecture rooms, buses, etc. If the ringtone is embarrassing to others, it becomes embarrassing, forgotten in the state of switching to the vibration mode, when the battery charger or desk drawer, placed on the desk, there is a problem that does not hear the ringing tone.

This is because there was no device developed to automatically determine whether the user who is using the mobile phone is carrying or not carrying the mobile phone. Therefore, the incoming call could only be set manually. It occurred.

On the other hand, when the mobile phone is being charged, it usually remains in a standing state. At this time, it is necessary to switch to the bell mode unconditionally because it is placed indoors, but in the prior art, there was no device capable of detecting and controlling such a problem.

In addition, when a user puts a mobile phone in a bag, a dresser, or clothes for long periods of time due to forgetfulness while the user switches the incoming call of the mobile phone to the vibration mode, there is a problem in that it is difficult to find the sound.

The present invention has been made to solve the above problems, the object of which is to automatically detect the state with and without the mobile phone carrying the incoming call can be automatically switched to vibration mode or bell mode, It provides an automatic switching device for bell / vibration mode of the mobile phone that can automatically detect when the phone is left for a long time while charging the phone or switch the incoming call of the mobile phone to vibrate mode. have.

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

As shown in FIGS. 1 to 9, hemispherical conductors 50 and 60 coupled to face each other with an insulator 20 interposed therebetween to form hollow spheres, and the hemispherical conductors ( Consists of an energizing ball 70 to roll on the inner surface of (50) (60).

Here, the hemispherical conductors 50 and 60 are formed in a hemispherical shape by forming a disk-shaped metal as shown in Figs. 62), and the flanges 52, 62 were welded with connecting terminals 54, 55, 64, 65 leading to the respective hemispherical conductors 50, 60, The insulating films 22 and 24 were formed to prevent the energizing balls 70 from being energized to each other when they were positioned at the joint portions of the hemispherical conductors 50 and 60.

In addition, instead of separately making the connection terminals 54, 55, 64, 65 on the hemispherical conductors 50, 60, the outer side surfaces of the hemispherical conductors 50, 60 may be wired or printed circuit boards. It can also be configured to be soldered to the pattern of 90) as it is.

In addition, two grooves each having a semi-conical shape are formed at the inner edges of the coupling portions of the hemispherical conductors 50 and 60 so that these two grooves meet and have a “V” shaped conical conduction groove ( 40 and 42 are formed so that the conical conduction grooves 40 and 42 are formed to face each other in a straight line, and are not covered by the insulating films 22 and 24 and exposed to the surface of the conduction ball. When contacted with 70, the two hemispherical conductors 50 and 60 were configured to switch to the energized state.

In addition, the center line formed by the two conical conduction grooves 40 and 42 is formed to be perpendicular to the vertical center line C1 of the mobile phone 30 so that the two hemispherical conductors only when the mobile phone 30 is laid horizontally. (50) (60) was configured to be energized.

The connecting terminals 54, 55, 64 and 65 welded to the hemispherical conductors 50 and 60 fix the hemispherical conductors 50 and 60 to the printed circuit board. When used to solder to the pattern, it is used as a contact point connecting the control unit 80 and the hemispherical conductor 50, 60.

In addition, when the hemispherical conductors 50 and 60 are mounted on the printed circuit board 90, a hemispherical conductor is formed by drilling a circular hole having a diameter slightly larger than that of the hemispherical conductors 50 and 60 at the installation position. After forming the slits into which the flanges 52 and 62 formed on the sieves 50 and 60 can be inserted in the longitudinal direction, and then inserting the hemispherical conductors 50 and 60 about halfway, the printed circuit board 90 When soldering the connection terminals 54, 55, 64 and 65 welded to the hemispherical conductors 50 and 60 to the circuit pattern, the hemispherical conductors 50 and 60 are fixed at the same time. You can connect.

On the other hand, the insulator 20 is formed into a flat ring shape by using a synthetic resin that is electrically insulated, and inserted between two hemispherical conductors 50 and 60 to insulate both hemispherical conductors 50 and 60. It serves to maintain the state, and is bonded between the flange 52, 62 formed in the hemispherical conductor 50, 60.

In addition, the insulator 20 may be formed of a coating layer formed on the close contact surface of the flanges 52 and 62 formed on the hemispherical conductors 50 and 60, and in this case, the insulator 20 is not configured separately. Insulation coated flanges 52 and 62 are directly bonded with an adhesive or the like.

In addition, the conduction ball 70 may be configured by using a metal ball, which is an electrical conductor, may be coated with a surface such as gold or silver to improve the electrical conductivity, the hemispherical conductor (50, 60) Is located in the conical conduction grooves 40 and 42 formed by coupling, and both hemispherical conductors 50 and 60 are in an electrically energized state, and when the hemispherical conductors 50 and 60 are located in either side. The insulating films 22 and 24 maintain the electrical failure state.

That is, the conduction ball 70 is located inside the hemispherical conductors 50 and 60 and rolls while being connected to the hemisphere conductors 50 and 60 according to the position of the mobile telephone 30. 54) (55) (64) and (65) inverts the signal detected in the "ON" or "OFF" state while serving as a position sensor for detecting the attitude of the mobile phone (30).

On the other hand, Figure 6 is a circuit diagram for explaining the connection relationship between the control unit 80 and the hemispherical conductors 50, 60 for detecting an energized state and switching the incoming call to the vibration mode or the bell mode. Likewise, if there is no change in the signal detected from the connection terminals 54, 55, 64 and 65 for more than a certain time, it is determined that the user does not carry it, and the incoming call is switched to the bell mode, and the connection terminals 54, 55 ( 64) If the signal detected from 65 is repeatedly changed "ON" and "OFF" several times within a predetermined time, it is determined that it is carried and switches the incoming call to the vibration mode, and the input port of the controller 80 When the charging signal of the mobile telephone 30 is detected through IP1, the incoming call is switched to the bell mode.

In addition, the controller 80 determines whether to switch the incoming call to the bell mode or the vibrate mode, and transmits a signal to an input port of a mobile phone controller (not shown) through the output port to control the incoming call. Inside, a microprocessor (CPU), a clock generator, a timer, a program memory (ROM), a data memory (RAM), and an input / output interface circuit are embedded therein.

One of the hemispherical conductors 50 and 60 is connected to the ground, and the other is connected to the power supply through the pull-up resistor R, and the hemispherical conductor 60 and the pull-up resistor R The connection point is connected to the input port IP0 of the controller 80.

In addition, if the hemispherical conductors 50 and 60 remain in the "OFF" state for a long time while the incoming call of the mobile phone 30 is set to the vibration mode, the controller 80 controls the mobile phone 30 to a certain place. (E.g., a bag, a chest, clothes, etc.), when determined to be left in a predetermined time limit (e.g., 10 hours or more) has elapsed, it is configured to easily switch to the bell mode to find the mobile phone 30.

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

6 and 10, when the power of the mobile telephone 30 is turned "ON", the controller 80 is reset to initialize the built-in timer in step S10 of FIG. In step S11, it is determined whether the bell / vibration switching mode is automatically set from the input port IP2. If the signal detected from the input port IP2 is low level ("0"), it is automatically set. It is determined that the operation is performed in the automatic mode irrespective of the user's setting, and in the case of the high level ("1"), the user setting is judged to be the manual setting.

When the bell / vibration mode switching is set as above, the control unit 80 checks the state of the other input port IP1 in step S12 of FIG. 10 to determine whether the mobile phone 30 is being charged or not in a non-charging state. In this case, when the signal detected at the input port IP1 is at a low level ("0"), the mobile phone 30 is determined to be charging, and the incoming call is unconditionally switched to the bell mode in step S13 of FIG. If the detected signal is at the high level ("1"), it is determined that the mobile phone 30 is in the non-charging state and proceeds to the next step.

In other words, when the mobile phone 30 is being charged, most of the mobile phone 30 is performed indoors, and automatically switches to the bell mode. When the mobile phone 30 is not charged, there are two cases of carrying or storing. Will be.

If the mobile phone 30 is determined to be in a non-charged state, the controller 80 checks whether the hemispherical conductors 50 and 60 are short-circuited as shown in FIG. It is determined whether it is lying almost horizontally or in other posture according to the state of another input port IP0. At this time, the data ("0" or "1") detected by the input port IP0 is determined. It stores the state in a register or data memory (RAM), stores the state, and starts the built-in timer to measure the time.

Then, the controller 80 detects and stores the state ("0" or "1") of the input port IP0 again, and then stores the port state ("0") stored in a specific register or data memory (RAM) in the previous step. When comparing the values with each other using a comparison means such as " or " 1 ") and exclusive logical sums, and determining that the result values are different, it is determined that the mobile telephone 30 is shaken for a very short time.

Then, the controller 80 determines whether the hemispherical conductor 50 or 60 is "ON" or "OFF" based on the signal detected from the input port IP0 in step S14 of FIG. If the data detected from the input port IP0 is "0" in binary, it is determined that the hemispherical conductors 50 and 60 are turned "ON", and the incoming call is switched to the bell mode in step S16. In contrast, in the case of "OFF", the mode is switched to the vibration mode in step S15.

That is, when the mobile phone 30 is placed in a flat place indoors (for example, on a desk, a desk drawer, etc.), the conical conduction grooves 40 and 42 on the hemispherical conductors 50 and 60 are positioned vertically downward. As the hemispherical conductors 50 and 60 are energized by the energizing ball 70, the input port IP0 of the controller 80 drops to the potential of the low level, and the detected signal is binary 0. When the mobile telephone 30 is detected, the incoming call is switched to the bell mode, and when the mobile phone 30 is held, the hemispherical conductor 50 ( 60 is set to the non-energized state in the " OFF " state, and the signal detected through the input port IP0 of the controller 80 becomes the binary number " 1 "

That is, the mobile phone 30 is shaken when the mobile phone 30 is carried while walking or using a transportation device, and the conduction ball 70 in the built-in hemispherical conductors 50 and 60 is moved therein. The hemispherical conductors 50 and 60 are turned on by the energizing balls 70 while passing through the conical conduction grooves 40 and 42 formed at the boundary of the hemispherical conductors 50 and 60 while rolling on a sphere. When " OFF " is repeated and at the same time, when the hemispherical conductors 50 and 60 are turned "ON", the signal of the low level ("0") is reversed in the input port IP0 of the controller 80, and vice versa. When the hemispherical conductors 50 and 60 are turned "OFF", a high level ("1") signal is repeatedly detected for a very short time, and the mobile phone 30 is shaken by detecting the change of the port. After detecting, it is determined that the portable device is to switch to the vibration mode.

Thereafter, the controller 80 stores the time value measured by the built-in timer in the data memory, and then detects whether the signal input from the input port IP0 has changed within the reference time in step S17 of FIG. If there is a change, the timer is reset in step S19 after switching to the vibration mode in step S18.

In addition, when it is determined in step S17 that there is no change in the state of the input port IP0, it is determined in step S20 how long the input port IP0 lasts in the "ON" or "OFF" state, and then the input is performed in step S23. If the port IP0 remains in the "ON" state, for example, for more than 10 seconds, the device switches to the bell mode in step S24, and in step S21 the input port IP0 is in the "OFF" state, for example, for more than 2 hours. If it is continued, the process switches to the bell mode in step S22.

This is because when the mobile phone 30 is stored in a bag or a chest for a long period of time, it is difficult to find an incoming tone and is difficult to find because the phone is switched to the vibration mode. This is for automatically switching to, so that you can easily hear the ringing tone and at the same time find it easily.

As described above, the present invention is configured to automatically switch to the vibration mode when carrying a mobile phone, and to automatically switch to the bell mode when the mobile phone is placed in a certain place without carrying. In addition, since the mobile phone is configured to switch to the bell mode unconditionally when charging or storing for a long time, the incoming call is more precisely made, and the mobile phone can be easily found.
