Abstract

PROBLEM TO BE SOLVED: To prevent destruction owing to falling by self-movement at a vibration information mode by suppressing the magnitude of vibration to a level self-movement is not caused when the magnitude of the actual vibration of a mobile communication terminal main body is the magnitude of the vibration of self-movement when vibration is activated. SOLUTION: A vibration magnitude control part 14A restricts the self-movement of a PHS terminal. That is, a vibrator 14 is driven when an incoming call arrives in a state where the PHS terminal is set to a vibration information mode. A vibration magnitude sensor part 15 measures the magnitude of the vibration (b) of the PHS terminal and a vibration magnitude comparison part 16 compares the magnitude of vibration (a) and the magnitude of vibration (b) which are stored in a maximum vibration quantity memory part 17. It is judged whether the magnitude of vibration (b) is smaller than the magnitude of vibration (a). When the magnitude of vibration (b) is smaller than the magnitude of vibration (a), the present magnitude of vibration (b) is maintained. When the magnitude of vibration (b) exceeds the magnitude of vibration (a), a vibration magnitude adjusting part 18 suppresses the current flowing in the vibrator 14. Thus, the number of revolutions of the vibrator 14 is reduced and consequently the magnitude of vibration (b) is reduced.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication terminal suitable for preventing falling due to self-movement during vibration of a vibrator, and a self-movement prevention method therefor.

[0002]

2. Description of the Related Art In recent years, a mobile communication terminal such as a PHS terminal has been provided with a vibration notification mode in which an incoming call can be surely recognized even in noise.

FIG. 6 shows an example of such a conventional PHS terminal.

The PHS terminal includes an ANT unit 1, a TRX 2, a baseband processing unit 3, an MCPU 4, a power supply 5, a receiver 6, a microphone 7, a display unit 8, a user IF unit 9, a number button 10, a data communication IF unit 11, and a driver. A part 12, a sounder 13, and a vibrator 14 are provided.

[0005] The ANT unit 1 transmits and receives radio signals.
The TRX 2 and the baseband processing unit 3 modulate and demodulate a wireless signal input and output. The MCPU 4 is the center of control of the functional operation of the PHS terminal.

[0006] The power supply 5 is a power supply for the PHS terminal. The receiver 6 is a receiver, and the microphone 7 is a transmitter. The display unit 8 displays a telephone number, a clock, and the like. User IF section 9

Is a vibration motor for transmitting a notification at the time of an incoming call by vibration.

In such a configuration, if there is an incoming call in a state where the vibration notification mode is activated, the vibration 14 vibrates. Therefore, by attaching the PHS terminal to the body, it is possible to reliably recognize the incoming call even in the noise due to the vibration.

[0009]

Incidentally, there is a case where the above-mentioned conventional PHS terminal is placed on a desk or a table in a state where the vibration notification mode is activated. If there is an incoming call in this state, the vibration of the vibrator 14 causes the PHS terminal to move by itself.

[0010] In this case, if the place where the PHS terminal is placed is soft, the vibration is absorbed, and the self-movement of the PHS terminal is small. However, like a desk or table,

As described above, when the self-movement of the PHS terminal increases, the PHS terminal may fall from a desk or a table.

In recent years, PHS terminals have become smaller and lighter,
Because of its low earthquake resistance, as described above, there has been a problem that, in the worst case, it may be damaged if it falls from a desk or table.

The present invention has been made in view of such circumstances, and provides a mobile communication terminal capable of preventing destruction due to a fall due to self-movement in a vibrating mode and a self-movement prevention method thereof. Is to be able to do.

Embodiments of the present invention will be described below. In the drawings described below, the same parts as those in FIG. 6 are denoted by the same reference numerals.

(First Embodiment) FIG. 1 is a block diagram showing a PHS terminal according to a first embodiment of a mobile communication terminal of the present invention, and FIG. 2 explains the operation of the PHS terminal of FIG. FIG. 3 is a flowchart for explaining the operation of the PHS terminal of FIG.

The ANT unit 1 transmits and receives radio signals.
The TRX 2 and the baseband processing unit 3 modulate and demodulate a wireless signal input and output. The MCPU 4 is the center of control of the functional operation of the PHS terminal.

The power supply 5 is a power supply for the PHS terminal. The receiver 6 is a receiver, and the microphone 7 is a transmitter. The display unit 8 displays a telephone number, a clock, and the like. User IF section 9
Recognizes the input of a plurality of number buttons 10 and
To communicate.

The data communication IF unit 11 is connected to another terminal (OA)
Connection terminal for data communication with a device or the like. The driver unit 12 as a driver receives a notification command at the time of an incoming call from the MCPU 4 and drives the sounder 13 or the vibrator 14. The sounder 13 is a speaker that emits a ringtone. The vibrator 14 is a vibration motor for transmitting a notification at the time of an incoming call by vibration.

A vibration amount control unit 14A serving as vibration amount control means
Has a vibration amount sensor unit 15, a vibration amount comparison unit 16, a maximum vibration amount memory unit 17, and a vibration amount adjustment unit 18.

Vibration amount sensor unit 1 as vibration amount sensor means
Numeral 5 is connected to the main body of the PHS terminal, and measures the vibration amount of the main body of the PHS terminal at the time of vibration at the time of an incoming call. The vibration amount comparison unit 16 serving as a vibration amount comparison unit includes an actual vibration amount b measured by the vibration amount sensor unit 15 and a maximum vibration amount a stored in a maximum vibration amount memory unit 17 serving as a maximum vibration amount memory unit. When the actual vibration amount b exceeds the maximum vibration amount a, the vibration amount adjusting unit 18 as the vibration amount adjusting means is controlled.

The maximum vibration amount memory unit 17 stores the maximum vibration amount (the level at which the PHS body starts to move due to vibration). The vibration amount adjustment unit 18 controls the current flowing through the vibrator 14 to suppress the vibration amount.

Next, the operation of the mobile communication terminal having such a configuration will be described.

First, FIG. 2 shows a change in the amount of vibration with respect to the hardness of the place where the PHS terminal is placed. The PHS terminal
The amount of vibration varies depending on the hardness of the place where it is placed. For example, when it is placed on a soft object, the vibration is absorbed by the soft object, so that the vibration amount is small. However, when the PHS terminal is placed on a hard object, the vibration force returns due to the reaction, and the amount of vibration of the PHS terminal increases.

As described above, the movement of the PHS terminal by the vibration is caused by the magnitude of the vibration. With a vibration amount lower than the dotted line shown in FIG. 2, the PHS terminal does not move by itself, but with a vibration amount higher than the dotted line, the PHS terminal moves by itself.

By the occurrence of such self-movement, P
The HS terminal falls from a desk or the like, leading to destruction.

Therefore, as shown in FIG. 3, the vibration amount control unit 14A of FIG. 1 regulates the self-movement of the PHS terminal.

That is, when there is an incoming call in a state where the PHS terminal is in the vibration notification mode, the vibration 14 is driven (step 301). At this time, the vibration amount b of the PHS terminal is measured by the vibration amount sensor unit 15 (step 30).
2). Further, the vibration amount a and the vibration amount b stored in the maximum vibration amount memory unit 17 are compared by the vibration amount comparison unit 16 (step 303).

Here, it is determined whether or not the vibration amount b is smaller than the vibration amount a (step 304). If the vibration amount b is smaller than the vibration amount a, the current vibration amount b is maintained (step 304). Step 305).

On the other hand, when the vibration amount b exceeds the vibration amount a, the current flowing through the vibrator 14 is suppressed by the vibration amount adjusting unit 18. Thereby, the rotation speed of the vibrator 14 is reduced, and the vibration amount b is reduced (step 30).
6).

Then, again, the vibration sensor 15
The vibration amount b of the PHS terminal is measured (step 30).
2). This operation is repeated until the vibration amount b becomes smaller than the vibration amount a.

By such an operation, the amount of vibration (less than vibration amount a) at which the PHS terminal does not move by itself can be reduced. Therefore, even if there is an incoming call with the PHS terminal in the vibration mode, the PHS terminal does not move. Can be suppressed.

As described above, in the first embodiment, when an incoming call occurs, when the vibrator 14 is driven by the driver unit 12, when the actual amount of vibration of the mobile communication terminal is the amount of self-moving vibration, Since the vibration amount is controlled by the vibration amount control unit 14A to a vibration amount that does not move by itself,
It is possible to prevent destruction due to falling due to self-movement in the vibration notification mode.

Further, preventing the destruction of the PHS terminal can save labor and unnecessary repair cost for the user of the PHS terminal. Further, the same can be said for the provider of the PHS terminal.

(Second Embodiment) FIG. 4 is a block diagram showing a PHS terminal according to a second embodiment of the mobile communication terminal of the present invention, and FIG. 5 explains the operation of the PHS terminal of FIG. It is a flowchart for performing.

In the second embodiment, the vibration amount control unit 14A in FIG. 1 is changed to a vibration amount control unit 14B. That is, the vibration amount adjustment unit 1 of FIG.
8, a notifying means changing circuit 19 which is a vibration amount adjusting means.
Is provided.

The notifying means changing circuit 19 switches the notifying means from the vibrator 14 to the sounder 13 (sound) in accordance with a command from the vibration amount comparing section 16.

Next, the operation of the PHS terminal having such a configuration will be described.

First, as shown in FIG. 5, when there is an incoming call while the PHS terminal is in the vibration notification mode, the vibration 14
Is driven (step 501).

At this time, P
The vibration amount b of the HS terminal is measured (step 502).
Further, the maximum vibration amount memory unit 1 is controlled by the vibration amount comparison unit 16.
The vibration amount a and the vibration amount b stored in the memory 7 are compared (step 503).

Here, it is determined whether or not the vibration amount b is smaller than the vibration amount a (step 504). If the vibration amount b is smaller than the vibration amount a, the current vibration amount b is maintained (step 504). Step 505).

On the other hand, when the vibration amount b exceeds the vibration amount a, the notification method is switched by the notification means changing circuit 19 from the vibrator 14 to the sounder 13 (sounding sound).

As described above, in the second embodiment, when the vibration amount b exceeds the vibration amount a, the notification means is switched from the vibrator 14 to the sounder 13 (sounding sound) by the notification means changing circuit 19. Therefore, similarly to the above, it is possible to prevent destruction due to dropping due to self-movement in the vibration notification mode.

Further, since the vibration is automatically switched from the vibrator 14 to the sounder 13 (sound), it is possible to prevent the user from noticing the incoming call due to forgetting to switch the incoming call notification mode (sound or vibration).

That is, when the incoming call notification is set on the desk with the vibration notification mode, the incoming call is often not noticed at all. In such a case, the sound is automatically switched from the vibration notification mode to the sound when the device is left on the desk, which leads to improvement in usability.

[0047]

As described above, according to the mobile communication terminal and the method for preventing self-movement thereof according to the present invention, when an incoming call occurs and the vibrator is driven by the driver means, the actual amount of vibration of the mobile communication terminal main body is reduced. In the case of the self-moving vibration amount, the vibration amount is controlled by the vibration amount control means to the vibration amount that does not move by itself, so that it is possible to prevent destruction due to dropping due to self-movement in the vibration notification mode.
