Abstract

PURPOSE:To recognize a telephone set having an incoming call immediately through an incoming call tone by recording a specific tone to each telephone set so as to set lots of kinds of incoming tones to telephone sets. CONSTITUTION:A telephone set circuit 1 is provided with a voice recording means to record a sound from a handset, a storage means 6 storing its content, a detection means 4 for an incoming signal, a voice synthesis means 8 converting the content from the storage means 6 into a read tone and a voice output means 9 outputting the sound from a speaker, and an incoming call is noticed by means of a sound stored in advance in the storage means 6 at the arrival of a call. Thus, a specific sound for each telephone set is stored in the means 6 and the sound is outputted in place of a bell tone on the arrival of a call.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a telephone that can make a call by outputting a prerecorded sound when an incoming call is received.

(Prior Art) A conventional telephone has a telephone circuit 21. as shown in FIG.
A rectifying circuit 23 for a calling signal sent from the handset as a 22.16 Hz signal. and an oscillation circuit 24 that operates with the voltage generated by the rectifier circuit 23. By sounding the signal generated by the oscillation circuit 24 through the speaker 25, an incoming call can be announced with sound. Note that the capacitor 26 is for DC cut.

(Problems to be Solved by the Invention) In the above-mentioned conventional telephone, the sound that can be output from the speaker is determined by the characteristics of the oscillation circuit, and therefore only two or three types of sound changes can be made. For this reason, when many telephones are placed in one room, it is difficult to know which telephone is ringing.

It is an object of the present invention to overcome the drawbacks of the prior art, and by recording a unique sound for each phone, it is possible to set a virtually unlimited variety of ringtones on the phone, and when the ringtone is heard, it is possible to tell which phone is ringing. The objective is to provide a telephone that is immediately recognizable.

(Means for Solving the Problems) The telephone of the present invention has a telephone circuit that includes a voice recording means for recording the sound from the handset, a storage means for storing the contents, and a 16-wire telephone that is an incoming call signal. A detecting means, a sound synthesizing means for reading the content from the storage means and converting it into a sound while the incoming signal is being detected, and an audio output means for outputting the sound from the speaker,
When an incoming call is received, the incoming call is notified by a sound stored in the storage means in advance.

(Function) According to the present invention, a unique sound can be stored in advance for each telephone, and by outputting that sound instead of a bell when an incoming call is received, it is possible to determine which telephone receives the call. You can recognize it right away.

(Example) An example of the present invention will be described based on FIGS. 1 to 3.

FIG. 1 is a block diagram showing the configuration of a telephone according to the present invention. In the figure, 1 is a conventional telephone circuit, 2 is a handset, and 3 is a DC cut capacitor.
It enters the detection means 4 of 16Hz.

Reference numeral 5 denotes a voice recording means, in which sound input from the microphone of the handset 2 is input through the telephone circuit 1, processed there, and recorded in the storage means 6. The start of this recording is notified to the audio recording means 5 by the switch 7. The thus recorded sound is extracted by the sound synthesis means 8 operated by the input from the detection means 4, and is outputted from the speaker 10 through the sound output means 9.

FIG. 2 is a block diagram of one embodiment of the present invention. In the figure, 1 is a conventional telephone circuit, 2 is a handset,
3 is a capacitor for DC cut.

Reference numeral 11 denotes a 167 detection circuit, which includes a photocoupler 11-1 and a circuit 11-2 that shapes the waveform of its output signal.

12 is an A/D (analog → digital) conversion circuit, 13
is a D/A (digital to analog) conversion circuit, which together with the timing and address generation circuit 14 constitutes the audio recording means 5 and the audio synthesizing means 8 shown in FIG. 15 is an amplifier, 10 is a speaker, and 7 is a switch for starting sound recording. 16 is a clock generation circuit for operating the timing and address generation circuit 14, and 17 is an R for recording sound.
AM (memory).

Next, the specific operation will be explained with reference to FIG.

To record sound, when the switch 7 is pressed, the timing and address generation circuit 14 operates for two seconds.

The sound to be recorded enters from the microphone of the band set 2, passes through the telephone circuit 1, and is input to the A/D conversion circuit 12. A
The /D conversion circuit 12 samples the input analog sound according to the timing and the signal from the address generation circuit 14, and writes it into the RAM 17. The address of the RAM 17 at this time is inputted by the timing and address generation circuit 14. RAM17 in this case
If the audio band is 4K) Iz, the capacity is normally sampled at 8 &, so if 8 bits are used in one sampling, 8 bits x
8000 times/second x 2 seconds = 128 bits = 16 bytes.

The capacity of 16 bytes is on the small side with current memory technology. Recently, technologies such as 1/2 compression and 1/4 compression have advanced, so this capacity can be easily achieved.

Next, the composite output will be explained. The signal for normal incoming calls is N.
The sound is sent at 16Hz from the TT converter. In this telephone, this signal is received by a photocoupler 11-1 and waveform-shaped by a waveform shaping circuit 11-2.

The 1611z incoming signal is normally sent at intervals of 2 seconds ON and 1 second OFF, but the relationship between this signal and the output of the waveform shaping circuit 11-2, that is, the timing and the A input signal of the address generation circuit 14, is as follows. Figure 3(a)
, (b). Here, the timing and address generation circuit 14 is configured such that the A input is ON as in the case of recording.
It operates when , and sends an address to the RAM 17 and at the same time sends a conversion timing signal to the D/A conversion circuit 13. Then, the D/A conversion circuit 13 reads the data from the RAM 17, converts it into an audio signal, and outputs the sound from the speaker 10 through the amplifier 15.

This timing is as shown in FIG. 3(c).

Incidentally, recently, A/D conversion circuit 12. D/A conversion circuit 13. Amplifier 15. Timing and address generation circuit 14. The clock generation circuit 16 is an inexpensive one-chip LSI.
This is used to create answering machines with IC recording.

As previously mentioned, the memory capacity used in the storage means of the present invention is negligible, so it can be easily implemented using a portion of an IC recording answering machine.

With the above, you can easily record sound.

It is possible to realize telephones each having a different ring tone.

(Effects of the Invention) According to the present invention, it is possible to easily set a unique ring tone for each telephone, and even in a place where many telephones are set, the ring tone of a specific telephone can be immediately recognized. People who don't like traditional ringtones can choose their favorite ringtone, which has great practical effects.
