JPS619060A - Ringer tone variable device for telephone set - Google Patents

Abstract

PURPOSE:To increase gradually a ringer tone at an incoming call and to attain ease of convenience of the user by providing an attenuator to the front-stage of a ringer and decreasing gradually the attenuation of the attenuator every time a call signal is transmitted. CONSTITUTION:When a hook switch 2 is turned on, a microcomputer 9 generates an initial set signal to set the attenuation of the attenuator by means of an attenuator control means to a maximum value. When a call signal S1 is transmitted, the 1st part of the signal S1 is detected while awaiting a time for one call signal's share thereby keeping the attenuation of the attenuator 10 in the amount of initial state during the signal part and a ringer drive signal S2 from a ringer driver signal output circuit 8 is attenuated to a maximum value. The microcomputer 9 detects on/off of a hook switch 2 and when ON, a control signal is generated to decrease the attenuation of the attenuator 10 by one grade. Similarly, the said operation is repeated and the sound volume is increased gradually every time a call signal comes.

Description

[Detailed description of the invention] Technical field of the present invention> Unreleased F! A relates to a variable ringer tone device in a telephone.

Background technology Currently, telephones in use have a ring tone (linker tone).
You can change the height to, for example, 3 levels using the manual switch, but if you select a height of A person nearby may feel discomfort, and if a low volume is selected, a person who is far away from the phone may miss the ringtone, making it less practical. was.

<Object of the present invention> The present invention was invented in view of the above-mentioned drawbacks of the conventional device, and provides a method for the convenience of the user by increasing the ringer tone at the time of incoming call each time a ringing signal is input. It is something that we try to do.

<Embodiment of the present invention> Configuration: An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a block electrical circuit diagram of a telephone equipped with a ringer tone variable device according to the present invention. In the figure, 1 is a line, and 2 is a function switch that is turned on and off as the handset 4 is raised and lowered. When the receiver is put down, the movable contact 2a is in contact with the fixed contact 2b (hereinafter referred to as ON), and when the receiver is lifted, the movable contact 2a is in contact with the fixed contact 2c. The time when the contact is in contact with the fixed contact 2c is hereinafter referred to as OFF.

A speech circuit provided between the fixed contact 2c of the hook switch 2 and the microcomputer 9,
It functions for communicating using the microphone 5 and speaker 6 of the handset 4.

7d Above - A calling signal detection circuit provided between the fixed contact 2b of the hook switch 2 and the microcomputer 9, when the receiver 4 is placed and the hook switch 2 is turned on, a call is made from the other party's telephone through the telephone line. Signal Sl
When the call signal is sent, it detects the call signal and supplies it to the microcomputer 9. As is well known, the calling signal Sl is a signal with a constant time width that repeats at a constant cycle (see FIG. 3).

Reference numeral 8 denotes a ringer drive signal output circuit which appropriately shapes the waveform of the ringing signal Sl and outputs a ringer drive signal S2.

An attenuator 10 changes the amount of attenuation of the ringer drive signal S2 under the control of the microcomputer 9, thereby changing the volume of the ringer sound (ringing sound) output from the ringer 11.

The microcomputer 9 is composed of a CPU (central processing unit) 12 that operates according to a program set in a ROM (read only memory) 13, a RAM (random access memory) 14, and an input/output port 15, as shown in FIG. As shown in FIG.
and the attenuator 10, and when the initial setting signal S4 is obtained, the attenuator initial setting signal sa is output.
Output k and set the attenuator lO to the initial state “
an attenuation variable signal that is set to the i state (the state in which the attenuation is maximum) and changes (reduces) the attenuation of the attenuator 10 every time the ringing signal S□ is obtained from the ringing signal detection circuit 7 at the time of an incoming call; It forms an attenuator control means 17 that outputs S6 and an incoming call end detection means 18 that detects the end of a ringing signal at the time of one incoming call.

Operation: The present invention is constructed as described above, and its operation will be explained next with reference to the flowchart shown in FIG.

If the handset 4 is placed and the hook switch 2 is turned on in the call hold mode, the hook switch state determining means 16
The attenuator 10, which receives the attenuator initial setting signal Ss from the attenuator control means 17 based on the initial setting signal S4 outputted from the attenuator 17, is set to the initial state with its attenuation level maximized (step 2).

Then, in step (3), the foot switch state determining means 16 determines whether the hook switch 2 is OFF, that is, whether the telephone receiver 4 has been lifted. 2 is OFF, YES
If it is determined, the hook switch state determining means 16 gives a capable signal S to the speech circuit 3 to place the speech circuit 3 in a capable state and proceeds to call processing (step 2). and,
If the hook switch 2 is turned on in step ■, that is,
When the receiver 4 is hung up, the process returns to step (2).

Also, if the answer is NO since the handset 4 is not lifted and the switch 2 is ON in the step (2) above, the process proceeds to step (2) and the attenuator control means 17 is activated to detect a call from the ring signal detection circuit 7. The presence or absence of the signal S1 is determined.

When the calling signal Sl is transmitted through the telephone line 1, the judgment is YES and the process proceeds to step (2), where the attenuator control means 17 controls whether the calling signal Sl is transmitted for the first time (signal portion S, . . . in FIG. 3). I will decide whether or not to do so.

If it is determined in this step (■) that this is the first ringing signal s1 at the time of one incoming call, the attenuation level of the attenuator IO is set to the initial state during the signal portion S11 by waiting for the time S for one ringing signal (step ■). the ringer drive signal S2 from the ringer drive signal output circuit 8 is attenuated to the maximum extent and supplied to the ringer 11, and the ringer 11 is caused to output the minimum previous ringer tone (ringing tone). (Step■)
.

Then, in the next step [phase], the attenuator control means 1
7 to determine the end of 1 ringing signal (1 ringer tone),
When finished, return to step ■.

Also, if NO is determined in the above step (2) since it is not the first time of the calling signal S1, the process proceeds to step (2) in which the attenuator control means 17 increases the volume by one step, and the attenuation variable signal is sent to the attenuator 10. S6 is supplied to lower the attenuation level of the attenuator 10 by one step.

According to this step, the attenuator 10 is
The ringer drive signal S2 is attenuated at the OWN attenuation level, and the ringer 11 outputs a ringer 1 sound having a volume one level higher than the first ringer sound (step (2)). Then, in step [phase], the attenuator control means 17 determines whether the ringer sound (1 ringing signal) has ended, and when it is finished, the process returns to step (2), and from then on, each time a ringing signal comes, the step Repeat [phase] and gradually increase the volume.

Then, when the ringing signal S1 disappears and the attenuator control means 17 determines NO in step (2), it is determined in step (2) whether or not the call from the caller has ended, and the answer is NO.
If YES, the process returns to step (2), and if YES, the incoming call end detection means 18 gives the attenuator control means 17 the same function as the initial setting signal S4, and turns on the attenuator lO. Set to initial state.

Also, if you lift the handset 4 during a call as described above, the hook switch 2 will turn OFF, so select YES in step ■.
When it is determined that the call has ended and the telephone receiver 4 is placed and the hook switch 2 is turned on, the process returns to step (2) and the attenuator 10 is set to the initial state.
f. Effects of the present invention> Since the present invention is configured as described above, when there is a call from a caller, the volume of the ringer tone can be gradually increased. Those who are close to the telephone will not feel any discomfort, and those who are far away from the telephone will know that there is a call when the ringer tone becomes louder, so there is no risk of them missing the call. It is an invention.
