Abstract

PURPOSE:To distinctly discriminate between an extension and a line wire by hearing by reading out digital data stored in a memory from this memory, and outputting it to a second converter when the result of decision from a call incoming detection.decision circuit is the call incoming signal of the extension. CONSTITUTION:A processor 20 stores the digital data received from an A/D converter 17 in an area 15a to store the ringing tone of the line wire in the case of the line wire, and in the area 15b to store the ringing tone of the extension in the case of the extension in accordance with the line wire.extension selection instruction of a key input means 21. The call incoming detection.decision circuit 7a detects the call incoming signal from a private branch exchange 2, and decides it to be either the call incoming signal of the line wire or the call incoming signal of the extension, and sends the result of this decision to the processor 20. The processor 20 reads out the data of each ringing tone according to the result of the decision, and sends it to a D/A converter 16, and it is converted into a sound by a speaker 10, and is outputted as the ringing tone. Thus, the ringing tone of the line wire and the ringing tone of the extension are set quite different from each other, and both the ringing tones are discriminated distinctly by hearing.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a telephone set, and more specifically, the present invention relates to a telephone set that is connected to a private branch exchange (including base units and handset units such as home telephones and parent-child telephones), etc., and that is connected to outside lines and extension lines. This relates to a telephone that can make calls.

[Prior Art] FIG. 2(a) is a block diagram showing a connection form between a telephone and a private branch exchange. The private branch exchange 2 is connected to the telephone office 3 by an external telephone line 4, and is connected to each of the internal telephones 1a, lb, . . . and an extension telephone line 5a,
5b, . . . are connected.

FIG. 2(b) is a block diagram showing the circuit configuration of a conventional telephone 1. As shown in FIG. The bridge circuit 6 connects the telephone line L
1. This is a circuit that is connected to L2 and always supplies power with a constant polarity to the internal circuit of the telephone even if the polarity of the telephone line is reversed (a condition that normally occurs when connecting to the other party when making a call). be.

The private branch exchange 2 connects telephones 1a to 1n from outside lines or extensions.
When a call is made to one of the telephones, an incoming call signal is output to that telephone.

At this time, on the telephone side, the incoming call signal detection circuit 7b detects the incoming call signal received via the bridge circuit 6, and outputs an incoming call detection signal to the bell sound generating section 8. Bell sound generator 8
receives this incoming call detection signal and generates a bell sound signal. The bell sound signal is amplified by an amplifier 9 and then output to a speaker 10. The ringing sound generator 8 continues to output the ringing signal until the handset 12 of the telephone is picked up or the caller hangs up.

When a ringing sound occurs and the handset 12 is picked up, the transmitting/receiving circuit 11 inside the dialer/transmitting/receiving circuit 11
At step b, the voice signal received from the telephone line is output to the handset 12, and the voice signal received from the handset 12 is transmitted to the telephone line, thereby starting a telephone conversation.

When making a call from this telephone to another telephone with an extension or outside line, the dialer lla inside the dialing signal/answering circuit 11 generates a dialing signal in response to the selection of the outside line or extension from the keyboard 13 and the key input. , output to the telephone line.

[Problem to be solved] With such conventional telephones, the ring tone is the same when receiving a call from an outside line and a call from an internal line, which causes inconvenience when responding to calls. was occurring.

Additionally, some telephones have a system that distinguishes between internal and external calls based on the interval between rings and the pitch of the sound, but it is difficult to distinguish between the two. , don't make mistakes.

The present invention is intended to solve the problems of the prior art, and it is an object of the present invention to provide a telephone that can clearly distinguish between internal and external calls.

[Means for Solving the Problem] The features of the telephone of the present invention for achieving this object are as follows:
a processor, a memory, an audio signal input means, a first converter that converts the audio signal received from the audio signal input means into digital data and sends it to the processor, and converts the digital data received from the processor into an analog signal. a second converter that converts and outputs the converted signal; and an audio output means that converts and outputs the analog signal received from the second converter into audio.
A telephone that has an incoming call detection reference judgment circuit that detects an incoming call signal transmitted from a private branch exchange, determines whether it is an incoming signal of an outside line or an incoming call signal of an extension line, and outputs the judgment result to a processor, and a key input means. When the processor stores the digital data received from the first converter in the memory in response to the instruction from the key input means, and receives the determination result from the incoming call detection dispute determination circuit, it determines that the extension is incoming. When the signal is a signal, the digital data stored in the memory is read out and output to the second converter.

If the determination result is an incoming call signal from an outside line, a preset bell sound may be output as in the past, but second digital data different from the digital data is stored in another area of the memory. The second digital data may be stored in the second converter and output the second digital data to the second converter when the processor receives a determination result that the signal is an incoming call signal of an outside line.

[Function] By recording the voice using the voice input means, the ring tone can be freely set. Therefore, it is possible to set the ring tone for the outside line and the ring tone for the extension line to be completely different, so that the two can be clearly distinguished.

Also, any sound or voice can be created according to the user's preference.

It is possible to set music etc. as a ringtone.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a telephone to which the present invention is applied. Note that the same components as in FIG. 2(b) are represented by the same symbols.

In Fig. 1, what is different from Fig. 2 is the jar.

audio input means consisting of a receiver 19 and an amplifier 18;
/D converter 17, memory 15, D/A converter 16, audio output means composed of amplifier 9 and speaker 10, key input means 21, and performs processes such as recording and reproducing ring tones. A processor 20 and a bus 14 for interconnecting these are provided, and the conventional bell sound generating section 8 is deleted.
The conventional incoming signal detection circuit 7b is replaced with an incoming signal detection/judgment circuit 7a.

The memory 15 stores a processing program (not shown) for the processor 20, and also includes an area 15a for storing an outside line ring tone and an area 1 for storing an extension line ring tone.
5b is provided.

As a procedure for setting a ring tone for an outside line or an extension line, the user first connects a microphone, audio equipment, etc. to the jack 19. Next, an outside line or an extension line is selected using an outside line/extension line selection button (not shown) of the key input means 21. After pressing the recording start button (not shown) of the key input means 21, the audio signal to be set as a ring tone is input to the jack 1.
Enter from 9.

When the recording start button is pressed, the processor 20
/D converter 17 starts operating. A/D converter 17
converts the audio signal received from the amplifier 18 into digital data at a constant sampling period, and sends it to the processor 20. The processor 20 converts the received digital data into
In the case of an outside line, it is stored in the area 15a for storing the ring tone of the outside line, and in the case of an extension line, it is stored in the area 15b for storing the ring tone of the extension line.

When the user finishes inputting the ring tone audio signal,
Press the recording end button (not shown) on the key input means 21. At this time, the processor stops the operation of the A/D converter 17, adds an end hood to the end of the digital data stored in the memory 15, and ends the ring tone setting process.

Note that the recording time is about 5 seconds to 30 seconds, and the storage area is set to a limited range that is allocated only for that time.

Next, the operation when outputting a ring tone will be explained.

When a telephone within the premises receives a call from an outside line or an extension, the private branch exchange 2 outputs an incoming call signal to the telephone. Different incoming signals are used depending on whether it is an outside line or an extension line.

This incoming call signal is output until the handset 12 is picked up to initiate a call or the calling party hangs up before the handset 12 is picked up.

The incoming signal detection/determination circuit 7a detects the incoming signal output from the private branch exchange 2, determines whether it is an outside line incoming signal or an extension incoming signal, and as a result of the determination, the incoming signal detection/incoming signal is detected.
A determination signal is sent to the processor 20. Incoming signal detection/
The determination circuit 7a outputs this incoming signal detection/judgment signal until the output of the incoming signal from the private branch exchange 2 stops.

When the processor 20 receives the incoming signal detection report determination signal from the incoming signal detection preference determination circuit 7a, the processor 20 converts the D/A converter 16
If the judgment result is an outside line, the ring tone data is read from the area 15a for storing the ring tone of the outside line, and if it is an extension line, the ring tone data is read from the area 15b for storing the ring tone of the extension line. The data is read out and sent to the D/A converter 16. This ringing tone data is D/A
It is converted into an analog signal by a converter 16 and then sent to an amplifier 9.
After being amplified by the speaker 10, the signal is converted into voice and output as a ring tone.

When the output of the incoming signal from the private branch exchange 2 stops and the incoming signal detection/judgment circuit 7a stops outputting the incoming signal detection Φ judgment signal, the processor 20 stops the operation of the D/A converter 16, Ends the ringtone playback process.

Note that when the processor 20 detects an end code from the ring tone data during the ring tone reproduction process, the processor 20 returns to the beginning of the ring tone data and repeatedly performs the ring tone reproduction process.

As described above, the audio input means comprised of the jack 19 and the amplifier 18 in the embodiment may include a microphone.

In addition, in the embodiment, the configuration is such that both the outside line ring tone and the extension ring tone can be freely set, but only one can be set freely, and the other is a preset bell tone as in the past. It is also possible to output something like this.

[Effects of the Invention] As can be understood from the above explanation, in the telephone of the present invention, the ring tone can be freely set, so the ring tone for the outside line and the ring tone for the extension line are completely different. You can set this to make it possible to clearly distinguish between the two. Further, it is possible to set any sound, voice, music, etc. as a ring tone according to the user's preference.
