Abstract

PURPOSE:To allow the user to easily discriminate which telephone set receives a call in case of using plural telephone sets used placed closely by generating a call tone specific to a telephone set. CONSTITUTION:A CPU 106 reads a setting value N of a rotary switch 113. The setting value N is a value to specify a relevant telephone set and set so that no identical value is selected in the telephone sets placed closely and in this case, the switch 113 is able to be set to 0-9, and for example, the lower one digit of an extension number is set. Then the CPU 106 adds an individual tone by N times and in case of N=0, the sound is not provided. Since the call tone specific to the telephone set is generated in this way, it is made easy for the user to discriminate which of plural telephone sets receives an incoming call in case of the plural telephone sets used placed closely.

Description

[Detailed description of the invention] [Industrial application field] TECHNICAL FIELD The present invention relates to a telephone.

[Prior Art] FIG. 4 shows a waveform IA of a conventional ringing tone used in the extension telephone 7. As shown in FIG. One cycle consists of a sounding period of time (TI) and an intermittent period of time (T2). Furthermore, during the sound generation period, the frequency a(fl) is turned on/off at every time (T3). This results in a ringing sound similar to the ringing of a bell.

In conventional telephones, even when a plurality of telephones are used in close proximity, the user is notified of an incoming call by a common ring tone.

[The problem that the invention is trying to solve] However,
In the above-mentioned conventional example, when a plurality of telephones are used in close proximity, the ring tone is common, so it is difficult for the user to distinguish which telephone received a call.

Means for Solving Problem E] The present invention provides a first ring tone that is generated during a first time period and a second ring tone that is generated during a first time period.
a first ringing tone generating means that generates the ringing tone again after the elapse of a period of time; a time setting device that presets the first time and the second time; and a second ringing tone that generates the second ringing tone during the second period of time. By providing a second ring tone generating means and a number setting means for arbitrarily setting the number of times the second ring tone is generated during the second time period, it is possible to generate a ringing sequence unique to the telephone. It is something that can be done.

[Example] An example of the present invention will be described with reference to FIGS. 1, 2, and 3.

FIG. 1 is a block diagram showing the configuration of a control section that controls a calling signal of a telephone using the present invention. In addition, FIG. 2 shows the CPU (Central l'rocessing) in FIG.
FIG. 2 is a control flowchart of UniL) l 06; Furthermore, 31:24 is a signal waveform diagram of each part of the configuration shown in FIG.

In FIG. 1, an oscillator (101) generates an original clock that drives each circuit in FIG. Programmer True Timer 1 (102) and Programmer True Timer 2 (10
3) is to count the timer value set by the CPU (106) using the original clock input from the timer (lot). On the other hand, the programmer full frequency divider (104) divides the original clock according to the frequency division ratio set by the CPU (106).

The CPU (106) monitors the line interface circuit (114) during standby, and when there is an incoming call, the I/
It is known via the O (Input Output) boat (105) (step Sl).

When an incoming call is detected, the CPU (106) starts timer 1.
(102), timer input (TI), timer 2 (
103) to the timer value (T3), and also the frequency divider (10
4), the frequency division ratio that generates the first frequency (fl) is
Each is set (step S2). Next, the gate circuit (107) is turned on by turning on the signal (c) via the I10 port (105) (step S3
). As a result, as shown in FIG. 3, the frequency (fl) is output as the output (a). Hook switch (112)
is turned on when the speaker picks up the handset (lll), and this situation is monitored by the CPU (106) via the I10 boat (lo5) (step S
4). When the timer 2 (103) detects that the time (T3) has ended without turning on the hook switch (112) (step S5), the CPU (106)
is connected to the gate circuit (107) via the I10 boat (105).
) is turned off (step S6). As a result, the output (a) is turned off as shown in FIG. And timer 1
If the sound generation period (TI) has not ended according to (102) (step S?), the CPU (106) waits for the hook switch (112) to be turned on until the time (T3) has elapsed according to timer 2 (103). After (Step S
8. S9), the gate circuit (107) is turned on again. The above operation is repeated until the end of time (T I ) as shown in FIG.

After this, the CPU (106) sends a timer start (T2) to the timer 1 (102), a timer start (T4) to the timer 2 (103), and a second frequency (T4) to the frequency divider (105). f2) are reset (step 5IO). After that, the setting Vfi (N) is read out from the rotary switch (113). This (N) is a value for individualizing each telephone, and is set so that adjacent telephones do not have the same value. In this example, the switch (113) can be set to numbers 0 to 9. For example, one possible method is to set the value of the last digit of the extension number.

In offices, phones are often assigned in order of extension number, so if you do this, you can easily
Effective for individualization. .

CPU (106) runs (N) times, then theory 1!11
Add a unique stop sound.

First, as shown in FIG.
12,513), turns on the gate circuit (107) (
Step 514).

As a result, the frequency a (f2) is output as the output (a). Further, after waiting until the timer value (T4) ends (step sts, 516), the gate circuit (107) is turned off (step 517). This turns off the output (a).

After repeating the above steps S12 to S17 (N) times (step 5ll), the CPU (106) waits until timer E1 (T2) ends (steps S18, 519) and starts over from the beginning. Here, if N=O, the above sounds are not added.

The output (a) is then passed through a low-pass filter (10B) to remove harsh harmonics, and then sent to an analog amplifier (1
09) and then drives the speaker (110).

These steps S4. S8. S12° During standby in S14, when the speaker picks up the handset (111), the hook switch (112) turns on and the CPU (
106) connects the gate circuit (107) to 110 boats (1
05). Therefore, output (a) is turned off and the ringing tone generated by speaker (110) is interrupted.

In this embodiment, the second frequency (f2) is used as the individualization signal.
We have explained the case where only . However, 4ii' of N)
When the value becomes larger than 1, it becomes difficult for human cognition to distinguish between the two. Therefore, if there is a value of (N) or more, for example, if it is greater than (n), then cpυ(106) is the previous (f2)
Even if the third frequency (f3) is used instead of , and the number of repetitions is (N-n+1), it can be implemented with the same configuration as in FIG. Also, if (f3) is insufficient, 4th. This is possible by using the fifth frequency.

Further, in the embodiments, the application to telephones has been described, but the invention can also be used in other applications such as communication terminal devices, etc., in which multiple devices of the same model are used in close proximity at the same time.

As explained above, according to this embodiment, the ring tone of a plurality of telephones of the same model is used at the same time (N).
Make it more individualized! This feature greatly improves the identification of each phone.

Furthermore, since the individualization according to this embodiment does not impair the auditory characteristics of the original ringing tone, when different models or multiple devices are used, the model discrimination based on the ringing tone can be performed using the ηf function using the first frequency fl as before. It is.

[Effects of the Invention] According to the present invention, when a plurality of telephones are used in close proximity, the user can easily tell which telephone received a call by generating a ring tone specific to the telephone. It is possible to make a distinction.
