The method of detecting the reception of the portable communication device and informing the wrist wearable reception notification device is a wired method or a wireless method. Here, a preferred embodiment of the wireless method will be described in detail with reference to the accompanying drawings.

1 is a diagram showing the overall configuration of the portable communication device 10, a transmitter 20 for notifying a wrist-wearable reception notification device when a reception is detected through the detection of vibration or light thereof, and a signal from the transmitter is detected. The wearable reception notification device 30 informing the user is configured, and FIG. 2 shows a block diagram of the transmitter 20, and FIG. 3 shows a block of the wrist wearable reception notification device 30. Figure 1 shows an embodiment.

Referring to the configuration and operation of the transmitter of FIG. 2, when a call is made to the portable communication device 10, the portable communication device drives a vibration or reception notification lamp and also flashes light through an LCD window, which causes vibration. Vibration or light detection unit 210 detected by a sensor or a light detection sensor (cds photoconductive cell), and when the detection is detected by the detection unit 210 is received by the central processing unit 1 (hereinafter referred to as CPU1) 220 The reason for driving the power supply unit 230 to supply power to the wireless processing unit is that even when no call is made, if the power is continuously supplied to the wireless processing unit, the power of the buttery is continuously consumed. When the power is supplied to the wireless processing unit, the high frequency signal generator 240 generates a high frequency signal (for example, 27 MHz) and inputs the multiplexer 250 to the digital code generated by the CPU1 220. Accordingly, the multiplexer 250 selects a high frequency signal and ground (hereinafter, referred to as GND). The signal generated in this way is shown in FIG. 4 together with the digital code. The high frequency signal is amplified by the high frequency amplifier 260 and transmitted through the antenna 1 270.

Now, the configuration and operation of the wrist worn reception notification device 30 of FIG. 3 will be described. When the signal transmitted from the transmitter 20 is received by the antenna 2 310, the band pass filter 1 (hereinafter referred to as BPF1) 320 is described. After removing the unnecessary signal through the amplified by the high frequency amplifier 330. The amplified high frequency signal is further removed through the second band pass filter 2 (hereinafter referred to as BPF2) 340 and input to the envelope detector 350 for AM detection to detect the amplitude of the signal.

The detected signal is converted into a digital code through the comparator 360, and then input to the controller 2 (hereinafter referred to as CPU2) 370. The CPU2 370 checks whether it matches the transmitter code of its own, and notifies the user if it matches. do. Methods of notifying the user include a method of driving a shaking device such as a speaker by a signal of a frequency lower or higher than an audible frequency, a method of applying a low voltage to the skin of the user, and a method of using a general vibrating element.

First, when a vibration device such as a speaker is used, the vibration device drive head 380 is driven to drive the vibration device with a low frequency signal (eg, 10 Hz) lower than an audible frequency or an ultrasonic signal (eg, 25 KHz) higher than an audible frequency. Do it.

FIG. 5 is a detailed block diagram of the vibration device driver 380 in the case of using a speaker as an embodiment of the vibration device driver. When a signal is received from the CPU2 370, the signal is supplied to the power supply unit 2381. Is driven to supply power to the signal generator 382. The signal generator 382, which is now powered, generates a low frequency signal (e.g., 10 Hz) or an ultrasonic signal (e.g., 25 KHz), and the speaker driver 383 drives the small speaker 384 with this signal. Is entered.

When the voltage is generated and notified through the user's wrist, the CPU2 370 drives the voltage generator 390. FIG. 6 shows a detailed block diagram of the voltage generator 390. When a signal comes from 370, the signal drives the voltage supply 381 to supply power to the oscillator 392. When power is supplied to the oscillator 392, a signal of a predetermined frequency (for example, 50 KHz) is generated. The signal is inputted to the multiplier voltage rectifying circuit unit 393 to create a voltage that can be sensed by a human wrist and then the switching unit. Enter (394). When a pulse type signal supplied by the CPU2 370 is received, the switching unit 384 receives the voltage supplied from the multiplier voltage rectifying circuit unit 393 only for a short time (for example, 0.1 second). 395) and then turn it off again, repeating it periodically (for example, at intervals of 0.5 seconds). This informs the user through the skin of the wrist.

Alternatively, when driving an existing vibration motor, the CPU2 370 drives the vibration driver 410.

Now, a case in which the wrist-wearing reception notification device 30 is driven by a low sound speaker and a voltage generator is described, and the appearance of a general vibrating device will be described.

First, the structure of the wrist wearable reception notification device 30 of FIG. 1 will be described with a reception notification device 31 and a band 32 that can be worn on the wrist, and the antenna 2 310 along the band. ) May be installed or installed inside the reception notification device.

When driving the speaker as an example of driving the shaking device, the vibration part of the speaker is installed as shown in FIG. 7 on the rear of the reception notification device 31 of FIG. In order to sense the wrist even when driven by the voltage generator, the voltage output terminal 395 and the ground terminal 396 of the voltage generator are connected to the rear of the reception notification device as shown in FIG. Install on either side of the band. In the case of using a general vibrating element, even if installed inside the reception notification device 31 can be installed inside because the user can sense, but it is more effective if it touches the skin like a speaker.

The existing mobile communication device has a problem that when a call is made, the phone rings and disturbs others, and a vibration mode is set to cope with this problem, but there is a problem that a user cannot recognize it. The present invention is a means for notifying the reception of a mobile communication device, by generating a low sound wave or ultrasonic wave to use its vibration or generate voltage, or by wearing a reception notification device using a general vibration motor element as a wristwatch of the user It can be sensed through the wrist so that the user can know the reception clearly without disturbing others.

In addition, the mobile communication device detects a call and informs the wrist wearable reception notification device to use a wired or wireless method. When wireless is used, a code can be assigned to prevent crosstalk.
