The telephone line is divided into a tip line and a ring line. When a ring signal (typically 13 to 68 kHz, 40 to 140 Vrms) is received from an exchange (not shown) connected to a telephone line (TR), the ring detector (12) generates a ring sound from the DC voltage obtained by rectifying it. It is fed to a tone riger (15) to generate ring sounds. That is, when a ring signal is received from an exchange (not shown) connected to telephone lines T and R, a ring sound is generated in the tone ringer 15. The tone ringer 15 has a ringer chip, which is widely known as Utility Model Publication No. 494 (July 2, 1981), which produces a softer and more elegant tone than a mechanical ring through the speaker. The tone ringer 15 may also make a ring sound using an integrated circuit device in which a melody is stored, as is widely known as Patent Publication No. 964 (August 3, 1984). At this time, when the receiver does not answer the call, the microcomputer 17 analyzes the ring signal detected by the ring detector 11, and the microcomputer 17 does not go off-hook even if a predetermined number of ring signals are received. ) Creates an off-hook state and controls the voice synthesizer 18 to send a pre-stored message to a voice network 13 so that the message stored on the telephone line (T, R) is delivered to the caller. And, the message conveyed by the talker is stored in the external memory 20 through the recording player 19 so that it can be reproduced and listened later. When making a call, the DTMF (Dual Tone Multi Frequency) signal generated from the dialer 14 is transmitted to an exchange (not shown) through the voice network 13, and the DTMF receiver 16 sends a special message to the caller. When transmitted as a DTMF signal, it is decoded to provide data to the microcomputer 17 so that the microcomputer 17 performs a corresponding process. For the microcomputer 17, the voice synthesizer 18 and the recording player 19, a separate direct current (DC)-direct current (DC) adapter (not shown) is used to supply power. Talk to the other party through the handset 23 connected to the voice network 13, and amplify the voice signal from the speaker amplifier 21 to drive the speaker 22 so that various tones or voices can be heard by the speaker 22. do.

4 is a block diagram showing an answering machine implemented using a ring tone generator according to the present invention, including ring detectors 10 and 31, voice network 13, dialer 14, DTMF receiver 16, and the like. A microcomputer 32, a voice synthesizer 33 and a memory 20 are provided.

When a ring signal (typically 40 to 140 Vrms, 13 to 68 Hz) is received from an exchange (not shown) connected to the telephone line T.R, the ring detector 31 detects the ring signal. That is, when the ring signal determined by the standard is input to the ring detector 31, the current control resistor R2 is provided through the AC impedance control capacitor C1 and the resistor R1 of the ring detector 31 as shown in FIG. The ring detection signal is provided to the microcomputer 32 by the photo coupler OC1 connected in parallel with

In the microcomputer 32, when the ring detection signal is input, the voice synthesis recording player 33 is controlled to generate ring sounds. First, in the on-hook state, the microcomputer 32 continuously checks the interrupt '0'. That is, if the rising edge of the interrupt is detected and detected, it counts up to the next rising edge and checks whether one cycle coincides with the cycle of the ring signal, and if it does not coincide with the cycle of the ring signal, returns to the on-hook state. Check if it is a dial pulse (DP). This is necessary so that when two or more telephones are connected, ringing does not occur on the telephones connected together when dialing in pulse mode on another telephone. If the analyzed ring detection signal is different from the dial pulse (DP normal 10 ppm or 20 ppm) and coincides with a predetermined period of the ring signal, the voice synthesis recording and playback player 33 is controlled to generate a ring sound. Voice synthesis recording player 33 records the ringer desired by the user, such as bird sound and natural sound, and stores it in memory, reproduces the pre-stored ring sound data and amplifies it in the speaker amplifier, and then announces the ring sound to the user through the speaker 22. Let's hear. If a ring signal is inputted while the user is absent and the user does not answer the call, the microcomputer 32 analyzes the ring signal detected by the ring detector 31 and turns off the hook signal even if a predetermined number of ring signals are received. If it does not go into the hook state, the microcomputer 32 creates an off-hook state and controls the voice synthesis recording player 33 to send a pre-stored message to a voice network 13 to a speech network 13. The message stored in, R) is delivered to the talker, and the message conveyed by the talker is stored in the memory 20 so that the message can be reproduced and listened later.

When the user wants to make a call, the DTMF (Dual Tone Multi Frequency) signal generated from the dialer 14 is transmitted to the exchange (not shown) through the voice network 13, and the DTMF receiver 16 allows the caller to make a special call. When the message is transmitted as a DTMF signal, it is decoded to provide data to the microcomputer 32 so that the microcomputer 32 performs a corresponding process. Passes with the other party through the handset 23 connected to the voice network 13, amplifies the voice signal from the speaker amplifier 21 to drive the speaker 22 so that various tones or voices can be heard by the speaker 22 do.

FIG. 5 is a flowchart illustrating a ring detection and ring sound enabling process performed by a microcomputer of an answering machine, such as FIG. 4, and detects a ring signal in an on-hook state and rings a ringing sound. Indicates until off-hook.

The on hook state step 50 is a state in which the handset of the telephone is normally placed. When the ring signal is input from the counterpart in the on-hook state, the rising edge of the ring detection signal is checked in the interrupt '0' activation step 51. If the rising edge is not input, the ring signal is not input, so the process goes to the on-hook state step 50. If the rising edge is detected, the counting cycle 52 counts the period of the input signal. In the count comparison step 53, the counted value is compared with the reference value of the preset ring signal, and if it does not match, the process goes to the on-hook state step 50, and if it matches, the process goes to the dial pulse detection step 54. In the dial pulse detection step 54, it is checked whether the input signal is a dial pulse and goes to the on-hook state step 50 if it is a dial pulse, and goes to the ring sound generation step 55 if it is not a dial pulse. The dial pulse detection step 54 is a step for preventing a ringing sound from being mistaken as a ring signal when dialing to make a call when several telephones are connected to the same telephone line. In the ring sound generation step 55, the voice synthesis recording player 33 is controlled to play the ring sound selected by the user and to play it through the speaker. When the ring sounds, the user picks up the handset of the telephone to off hook. In the off-hook check step 56, it checks whether it is off-hook so that the user can make a call with the other party through the voice network in the off-hook state step 57. In addition, it is possible to provide a ring sound even in the event of a power failure by mounting the battery 34 to supply power even during power failure.
