Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone incoming / calling device which can be used in combination with a mobile phone, a personal handyphone system (PHS) or the like to enhance the usability of these devices.

[0002]

2. Description of the Related Art Mobile phones (including PHS; the same applies hereinafter)
When receiving in the standby state where the power switch is turned on, emits an incoming signal notifying the base station of the reception. The base station I of the mobile phone that issued the incoming signal
Check the D number and search for data such as whether the fee has not been paid. As a result, when the ID numbers match and no bad data such as unpaid charges is not found, the caller is connected and the call is permitted.

The call of the mobile phone is usually made by ringing a bell (electronic buzzer) like an ordinary telephone for indoor use, but due to the peculiarities of the mobile phone, an incoming signal is generated by vibration regardless of the sound. There are a lot of things to inform. The general structure of the vibrator used for this purpose is that the weight is eccentrically attached to the output shaft of a so-called micro motor, and the weight causes vibration when the output shaft rotates. .

If the vibrator of this system is housed in the body of the mobile phone, the mobile phone can be recognized at the part where the vibration of the body is felt, and the incoming call can be recognized without sound. Currently, the number of cell phones of this kind is extremely small. One of the devices devised there and the number of users is rapidly increasing is one in which a vibrator, a battery as a power source, and a receiver for receiving an incoming signal of a mobile phone are put in a single case. This is to notify an owner of an incoming call by operating a vibrator when an incoming signal of a mobile phone is received by a receiver.

By the way, since the frequency of the incoming signal of the mobile phone does not change the frequency for each terminal, the vibrator can receive the incoming signal of the mobile phone within a range (for example, a radius of 1 to 2 meters). If there are multiple people with mobile phones in
The vibrator will be activated by the incoming signal sent by anyone of the mobile phones. Therefore, there is a possibility that the user's mobile phone may be mistakenly recognized as an incoming call. In addition, it may be sensitive to radio waves other than the incoming signal of the mobile phone, such as radio waves of a broadcasting station and mobile radio devices.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of this point, and makes it difficult to respond to signals other than the incoming call signal of one's own mobile phone, and also when the mobile phone is about to be misplaced. The present invention intends to provide an incoming call calling device for a mobile phone which generates a vibration and notifies it.

[0007]

The present invention is, as means for solving the above problems, in the invention as set forth in claim 1, the main body of the mobile phone receives the incoming signal of the mobile phone. A transmitter and a transmitter that emits a weak electric wave at all times and stops emitting electric wave only when the receiver receives the signal, and a receiver that receives the weak electric wave from the transmitter A receiver having a controller for activating the vibrator when the output signal of the receiver becomes null is provided.

Further, in the invention described in claim 2, a receiver for receiving an incoming signal of the mobile phone and a weak radio wave are constantly emitted to the main body of the mobile phone, and when the receiver receives the signal. , A first pulse signal that continues for a predetermined time,
A second pulse signal fired following the first pulse signal to represent the ID signal of the mobile phone and a third pulse signal fired following the second pulse signal to represent the incoming code of the mobile phone. A transmitter main body having a transmitter for transmitting a combination of pulse signals is mounted, and a receiver for receiving the weak electric wave of the transmitter and a vibrator when receiving the first and second pulse signals are operated. A receiver having a controller is provided.

Further, in the invention described in claim 3, in the invention described in claim 1 or 2, the operation of the transmitter of the transmitter is intermittently repeated in a short time to operate the receiver of the receiver. Is intermittently repeated at a time slightly changed from the operating time of the transmitter.

According to the first aspect of the present invention, the weak radio wave is always emitted from the transmitter when the mobile phone is not used, and the radio wave is stopped when the mobile phone is called. When the radio wave stops, the side activates the vibrator to notify the user that the call has arrived. The vibrator operates when the radio wave stops, so if you try to leave the place with the mobile phone left somewhere, the radio wave that is being emitted at that time will not reach and the vibrator will operate, Notify the owner of the misplacement. Since the radio waves emitted from the transmitter are extremely weak, they are not sensitive to the radio waves of other people's mobile phones, broadcasting stations, mobile radio devices, and the like.

According to the invention described in claim 2, there are three kinds of radio waves emitted from the transmitter, and the receiver has the second pulse signal representing the ID number and the third pulse representing the incoming code. The vibrator is activated when a signal is detected. Then, when the third pulse signal is not detected, the vibrator is not operated. This invention differs from the invention described in claim 1 in that the radio wave emitted from the transmitter is not stopped even when the mobile phone receives an incoming call.

According to the third aspect of the present invention, the transmitter emits the radio wave and the receiver receives the radio wave intermittently, so that the consumption of the battery can be reduced. The operation of the receiver of the receiver is intermittently repeated in a time slightly shorter than the operation time of the transmitter of the transmitter, so that the receiver does not miss the signal from the transmitter.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention corresponding to claim 1 will be described with reference to FIG. Reference numeral 1 is a mobile phone, and 2 is a transmitter integrally attached to the main body (casing) of the mobile phone 1 by a double-sided adhesive tape or the like. A weak radio wave 3 is intermittently emitted from the transmitter 2, and the receiver 4 receives the radio wave 3. Although the configurations of the transmitter 2 and the receiver 4 will be described later, the receiver 4 has a built-in vibrator, and vibration of the receiver 4 informs the person carrying the vibrator that the mobile phone 1 has arrived.

FIG. 2 shows a circuit configuration of the transmitter 2. The transmitter 2 receives the incoming signal of the mobile phone 1 and the output signal of the receiver 5, and stops the output of the transmitter 7 of the next stage only when there is the output signal, When there is no output signal at 5, the controller 6 is configured to generate an output signal at the transmitter 7, and the power supply circuit 8 serving as a power supply. The power supply circuit 8 receives an intermittent signal from the controller 6 and supplies power to the transmitter 7 in response to the signal.

The receiver 5 is composed of a tuning circuit composed of a coil and a capacitor, a diode for rectifying the output signal of the tuning circuit, and the like, and when an antenna 9 housed in the case of the transmitter 2 receives a radio wave. , Generates an output signal of a predetermined level on the output side. The tuning circuit has a wide bandwidth and is adapted to handle incoming signals of all mobile phones. However, the receiving sensitivity is made extremely small so that it does not react to radio waves other than the mobile phone 1 to which the transmitter 2 is attached.

The input side of the controller 6 is connected to the output side of the receiver 5. The controller 6 is composed of, for example, an inverter circuit and a timer circuit, and has an inverting function of preventing an output from being generated when an input is made, and a function of intermittently generating an output at a constant interval, for example, every 2 seconds. The power supply circuit 8 intermittently supplies power to the transmitter 7 in response to this signal. The transmitter 7 has a weak output and emits an output radio wave corresponding to the output of the controller 6. Like the antenna 9 of the receiver 5, the antenna 10 of the transmitter 7 is also housed in the case of the transmitter 2.

FIG. 3 shows the circuit configuration of the receiver 4. The receiver 4 includes an antenna 11, a receiver 12, a controller 13, a vibrator 14, and a power supply circuit 15. The circuit of the receiver 12 uses a transistor, an IC or the like, but the tuning frequency is adjusted to the oscillation frequency of the transmitter 7 of the transmitter 2.

According to the invention described in claim 3, the controller 13 intermittently issues the output signal at a constant interval slightly shorter than the intermittent time of the controller 6 of the transmitter 2, for example, at an interval of 1.8 seconds, and the receiver 12 Control the power supply to. The controller 13 also controls the vibrator 14 to operate when the output signal of the receiver 12 is cut off. The output signal of the receiver 12 is interrupted when the power supply is cut off by the controller 13 and when the radio wave stops coming from the transmitter 7 of the transmitter 2. In the former case, the power supply to the vibrator 14 is supplied. Vibrator 14 only in the latter case
Works.

The vibrator 14 operates by being controlled by the output signal of the controller 13, and when operated,
The case of the receiver 4 is vibrated. The structure for generating the vibration is not limited, but as an example, a structure in which a weight is eccentrically attached to the output shaft of a small motor can be considered.

Both the power supply circuit 8 of the transmitter 2 and the power supply circuit 15 of the receiver 4 are composed of a battery and a switch circuit (not shown). A small battery such as a so-called button battery is used as the battery. Since both the transmitter 2 and the receiver 4 are made to flow an electric current intermittently, the power saving effect is enhanced, and even this type of battery can be used for a long time.

The operation will be described. The oscillator 7 of the transmitter 2 attached to the mobile phone 1 intermittently emits radio waves from the antenna 10 at regular intervals when the mobile phone 1 is not used. The intermittent timing is, for example, every 2 seconds as described above. When the mobile phone 1 is called from the base station, the mobile phone 1 emits an incoming signal to the base station. The receiver 5 of the transmitter 2 receives this radio wave and stops the operation of the transmitter 7 via the controller 6.

The receiver 12 of the receiver 4 worn by the user of the mobile phone 1 always receives the radio wave 3 from the transmitter 2. As described above, the vibrator 14 does not operate while receiving this radio wave. When the mobile phone 1 sends an incoming signal to the base station, the transmitter 2
Oscillator 7 stops oscillating. Then, no output is produced in the receiver 12 of the receiver 4, so the controller 13 activates the vibrator 14 to notify the owner of the mobile phone 1 wearing the receiver 4 of the incoming call. This puts you in a call.

In this way, the vibrator 14 of the receiver 4 is
Is activated when the receiver 12 stops receiving radio waves, the owner of the mobile phone 1 tries to leave the mobile phone 1 somewhere and leaves a certain distance (for example, 1 to 2 meters). Also, it operates even when the receiver 4 cannot receive the radio wave from the transmitter 2.
As a result, misplacement can be effectively prevented.

FIG. 4 shows the difference between the intermittent operation time of the transmitter 2 and the intermittent operation time of the receiver 4. Transmitter 2 has a fixed time (2 seconds as an example)
Do intermittent operation once. When the receiver 4 confirms the radio wave 3 from the transmitter 2, the receiver 4 turns off at the same time as the transmitter 2, and the timing to turn on next is slightly earlier than the operation of the transmitter 2 (transmitter 2GA is 2 seconds while receiver 4 Is 1.8 seconds)
The reception operation starts from. Then, it waits for a radio wave from the transmitter 2.

By operating in this way, the intermittent operation of the transmitter 2 and the receiver 4 can be synchronized. Therefore, when the radio wave 3 from the transmitter 2 is cut off, the receiver 4 will not be turned off. When the receiver 4 cannot confirm the radio wave 3 even after waiting for several times (2 seconds × 3 times = 6 seconds), the receiver 4 stops the reception operation and operates the vibrator to notify the owner.

FIG. 5 is a waveform diagram showing that the contents of the radio wave emitted by the transmitter 2 are changed in accordance with the invention described in claim 2. This emitted radio wave has a first pulse signal A that continues for a predetermined time, a second pulse signal B that is emitted following the first pulse signal to represent the ID number of the mobile phone, and an incoming code of the mobile phone. In order to express, the second pulse signal is combined with a third pulse signal C which is emitted subsequently. In the case of this embodiment, the first pulse signal A is constantly emitted from the transmitter 2, and the second and third pulse signals B and C are emitted at the time of reception.

The first pulse signal A is one, but the second and third pulse signals B and C are plural respectively. Regarding the length (time) of the three kinds of pulse signals, the first pulse signal A is the longest, and the second pulse signal B and the third pulse signal C are shorter (B> C),
The lengths of the second and third pulse signals B and C may be reversed.

When the combined radio waves are emitted from the transmitter 2, the receiver 1 of the receiver 4
2 receives intermittently at a longer interval than the transmitting side so that all of the first to third pulse signals A to C can be received. This reception is performed several times, and when the ID number of them is matched and the third pulse signal C which is the incoming signal can be detected, it is determined that the mobile phone has received, and the vibrator 14 is activated. Deliver the incoming call to the owner.
If the third pulse signal C cannot be detected even if the radio wave from the transmitter 2 is received, it is determined that there is no incoming call and the vibrator 14 is not operated.

Also in this embodiment, the receiver 4
In addition, the function of activating the vibrator 14 when the radio wave from the transmitter 2 cannot be detected is given. As a result, the owner of the mobile phone 1 tries to leave with the mobile phone 1 left somewhere, and when the mobile phone 1 is separated by a certain distance (for example, 1 to 2 meters), the transmitter 2
When the receiver 12 of the receiver 4 is no longer able to receive the radio wave of, the operation is performed and the misplacement is prevented. In this case, if the way of movement of the vibrator 14 is changed depending on whether it is an incoming call or a misplacement, it becomes possible to know whether the incoming call or the misplacement has occurred.

[0030]

Since the present invention is the incoming call calling device for a portable telephone configured as described above, according to the invention described in claim 1, it malfunctions in another person's portable telephone or other wireless equipment. It is possible to obtain an incoming call device that does not cause Further, in the invention described in claim 2, since the incoming signal is detected in the radio waves emitted from the transmitter, and the vibrator is activated when the incoming signal is detected and the ID number is also matched, a plurality of mobile phones are provided in the vicinity. , The vibrator can be activated for only a specific one of them, thus eliminating any malfunction. Further, according to the invention described in claim 2, the power saving effect is enhanced and the battery can be used for a long period of time.
