The second timer unit 104 may provide an initialization signal to the first timer unit.

In addition, a DC power supply means 106 for supplying operation power to the voice storage and reproducing means using a battery or the like, and a voice output for outputting the voice signal reproduced by the voice storage and reproducing means to the outside through a speaker or the like. Means 107 should be provided.

In addition, the ring tone control means must be provided with a ring signal rectifying means 108, in order to block the ring signal entered through the trunk line connecting means to the telephone, by forming the rectifying means as a bridge diode, AC signal The in-ring signal is blocked from being transmitted to the telephone side, but it is also preferably configured to form a call circuit between the exchange and the telephone in the off-hook state at the telephone side.

In addition, the ring tone control means includes a voice detecting means 109 for detecting and amplifying a voice signal on a call circuit formed between the trunk line connecting means and the telephone connecting means and providing the voice signal to the voice storing and reproducing means. It has a function of recording the user's preferred voice data to the voice storage and playback means in the connected state. The apparatus may further include a voice input unit 110 which receives voice data from an external voice signal source through a microphone or the like and provides the voice data to the voice storage and reproducing means.

By further comprising a second setting means 118 for setting or releasing to a mode, it is possible to record or play desired voice data if the user intends.

The operation of the telephone ringing remote call device using the wired control method of this configuration is as follows.

First, in the reproducing operation, when a ring signal comes through the trunk line at the telephone exchange, the ring signal detecting means 101 detects the ring signal and rings the first timer 103 and the first display means 111. The sensing signal is applied, and the ring rectifying means 108 rectifies the ring signal, which is an AC component, so that the ring signal does not flow to the telephone side so that the ring of the telephone does not ring.

In addition, the first display unit 111 is driven by the ring detection signal to confirm to the user that the ring signal is detected, and at the same time, the first timer unit 103 is set by the coupling of the resistor and the capacitor. The operation is started by the time constant, and the voice reproduction control signal is generated at the output terminal at the same time as the ring signal is detected. Therefore, the voice storage and reproducing means 105 reads the voice data already stored in the internal flash ROM to read the speaker. Output to the outside through the voice signal corresponding to the ringtone starts to output.

At the end of the reproducing operation, a short signal of a few seconds (12 msec) is output to the second display unit 112 by a reproducing completion signal (eom) generated in the flash ROM inside the voice recording and reproducing means. The light emitting diode of the second display unit 112 is turned on by this output signal. At the same time, the first timer unit 103 is initialized by this signal, and the first timer unit 103 stops its operation. If the operation of the first timer unit 103 is stopped between the ring and the ring, the first timer unit 103 stops the playback operation until the next ring signal comes.

By the way, when the voice recording and reproducing means 105 is playing back as described above, when the hook of the telephone is lifted (off-hook state), the second timer portion 104 is operated by the output of the hook signal detecting means 102. do. As the second timer unit 104 operates, the first timer unit 103 is initialized by the output signal of the second timer unit 104, and therefore, the reproduction of the voice chip is stopped at the same time.

Next, in the recording operation, the recording operation is possible when the existing telephone is connected to the telephone connection means 12, and the voice and other various kinds of voice signals are detected by the voice detection means 109 at the tip and the ring. And it may be amplified and input to the voice storage and playback means 105, and may also be input through an external voice input means (there is a microphone or the like separately mounted to enable voice input from the outside). When the user presses the first setting means (recording key), the input signal is stored in the flash-ROM inside the voice storing and reproducing means 105, and can be reproduced by a future play button or ring signal.

The above can be made when the output voltage of the DC power supply means 106 is normally supplied, and when the output (battery voltage) of the DC power supply means is normally supplied, the low power detection means 113 that operates in a low voltage state and Since the ring control signal output of the ring signal detecting means 101 is blocked by the ring control means 114, the ring generating means 115 does not operate normally. On the contrary, when the output (battery voltage) of the DC power supply means falls below a predetermined value, the voice storing and reproducing means 105 does not operate, so that the low power detecting means 113 and the ring control means 114 As a result, the interruption of the ring control signal output of the ring signal detecting means 101 is released, so that the ring generating means 115 operates to generate a ring signal in a low voltage state.

Since it is the same as the structure and function of 1, detailed description is abbreviate | omitted and only the part different from the case of FIG. 1 is demonstrated below.

In the fixing device 210 of FIG. 3A, the ring detection signal of the ring signal detection means or the hook detection signal of the hook signal detection means is encoded through each data line in order to implement a wireless control method, and the encoded data is encoded. A radio transmitting means 201 is provided to modulate a radio frequency signal and radiate to the air. A DC power supply means 217 is provided to supply operating power to the radio transmitting means.

Operation of the telephone ringing remote call device using the wireless control method of this configuration is as follows.

First, in the reproducing operation, when the ring signal enters the fixing device 210, the ring signal detecting means 211 generates a ring detecting signal and provides it as an input of the encoding unit 201a of the wireless transmitting means 201. The encoding unit 201a encodes the ring detection signal through a data line. At this time, the address is encoded at the front of the encoded data. The encoded signal is loaded on a carrier wave generated by the first oscillator 201b, converted into a radio frequency signal, and then transmitted to the wireless driver 201c, and the transmitted signal is radiated to the air through the transmission antenna 201d.

At the end of playback, a short signal of several seconds (12 msec) is output to the second display unit 222 by the playback end signal inside the audio storage and playback means 225, whereby the light emitting diode is turned on by the output signal of this terminal. At the same time, the first timer unit 223 is initialized by this signal, and the first timer unit 223 stops the operation. If the voice recording and reproducing means 225 is playing, the hook detection signal of the hook signal detecting means 212 is also decoded by the hook signal detection means 212 when the hook of the telephone is turned off (off-hook). It may be output from 202a, and this signal may operate the second timer unit 224. As the second timer unit 224 operates, the first timer unit 223 is initialized by the output signal of the second timer unit 224, and thus the reproduction of the voice chip is stopped at the same time.

On the other hand, in the recording operation, the existing telephone is connected to the telephone line connecting means 12 of the fixing device, and the voice and other voice signals are transmitted by the voice detecting means 219 (or voice input means). After being detected and amplified by the ring (telephone line), it is input to the voice storage and reproducing means 225 of the portable apparatus 220 by the prepared mono cable. Then, when the user presses the record button, the operation mode of the voice recording and reproducing means is set to the storage mode, so that the signal detected and amplified by the voice detecting means 219 is an analog input signal of the voice recording and reproducing means 225. The transmitted signal is stored in the flash-rom inside the voice storage and reproducing means 225, and may be reproduced in the future by a play button or a ring signal.
