Description

Call indication device of telephone

The present invention relates to an incoming call display device of a telephone, and more particularly, to an incoming call display device of a telephone for providing various kinds of incoming signals for informing a user of an incoming call.

The telephone is one of two-way (Duplex) communication devices that can communicate voice signals over long distances. Such a telephone can be classified into a landline telephone and a cordless telephone. Recently, a wired / wireless combined telephone which has a telephone line connected to one telephone line and can be conveniently used wirelessly through a plurality of portable devices is widely used. It is used.

In addition, with the development of the telephone, various functions are provided in the telephone. For example, a phone with an alarm function that outputs a ringtone at the scheduled time, an automatic connection that automatically dials an external contact when the call arrives, and an answering machine that automatically answers in the absence of the caller. It is released in various ways.

1 is a block diagram for explaining output control of an incoming signal in a conventional telephone.

As shown in FIG. 1, such a general telephone has an incoming signal detector 10 for detecting a voice signal induced at a communication terminal (a, b) branched from a public telecommunication network (1). The incoming signal detection unit 10 includes a photodiode PD1 and a photo transistor PT1 for detecting an incoming signal of a telephone. The output terminal of the incoming signal detection unit 10 controls the operation of the various functional blocks constituting the telephone, and is equipped with a microcomputer 20 for controlling it when performing the answering machine function.

One side of the microcomputer 20 receives a display device 30 for visually displaying the operation state of the phone and a key for setting an additional function in the phone, and a key corresponding to a unique number of the counterpart to be called. Key input unit 40 is connected.

In addition, the output terminal of the microcomputer 20 is connected to the voice output unit 50 consisting of an amplifier (AMP1) for notifying the outside when the signal is received from the telephone and a speaker 52 for outputting the buzzer sound.

When the voice signal is induced to the communication terminals a and b through the public telephone network in the conventional telephone, the photodiode PD1 of the incoming signal detection unit 10 is operated. When the photodiode PD1 is operated, the phototransistor PT1 installed to be spaced apart from the photodiode PD1 by a predetermined distance is operated to input an incoming signal of a telephone to the microcomputer 20. Therefore, the microcomputer 20 detects that the call is received. When the incoming signal is detected in the telephone, the microcomputer 20 outputs a control signal to the voice output unit 50 and outputs an alarm signal to the user through the speaker 52. The user hears the alarm signal output from the telephone and recognizes that the telephone is incoming.

However, in the conventional telephone, when the incoming signal of the telephone indicating that the voice signal is received from the outside is uniformized by the alarm sound output through the voice output unit, the telephone is not disturbed by the child room or the incoming signal that requires quietness. There is a problem in that the use of the phone is inconvenient because there is no other method than to disconnect the power plug.

The present invention was devised to solve the above problems, and an object of the present invention is to output the incoming signal indicating that the phone is received, except for ringtones, and other voice signals such as vibrations and lights, and variously output the convenience of using the phone. It is to provide an incoming display device of a telephone to be enhanced.

The telephone according to the present invention has a separate receiving device 200 capable of detecting an incoming signal of the telephone in addition to the main body 100. The called device 200 is configured to be worn by the user so that the user can be informed whether the call is received by vibration or light emission when the user inputs a separate call mode to the main body 100. The main body 100 of the telephone is equipped with a transmission microcomputer 110. When the incoming signal is input, the transmission microcomputer 110 mounted on the main body 100 inputs a corresponding signal to the main body transmission unit 120. The main body transmitter 120 is a modulator 122 for modulating the unique signal input from the transmission microcomputer 110 into a specific frequency band, and a high frequency oscillator 124 for oscillating a high frequency for transmitting the modulated frequency to a long distance. It is composed. An output antenna 130 for transmitting a signal is connected to an output terminal of the high frequency oscillator 124.
