Abstract

PURPOSE:To cancel a 'noisy' incoming sound to a person near a telephone set and to eliminate the inconvenience of the incoming sound not to be heard by automatically adjusting incoming sound volume according to the number of times of reception by the counting circuit of an incoming signal. CONSTITUTION:When the incoming signal arrives, the incoming sound is rung by a bell 4 and the signal is detected by an incoming signal detecting circuit 1. Then, the contact r3 of an A relay 3 is operated and a make is executed during one second, in which the incoming signal stays. By periodically repeating the sending and stopping of the incoming signal, an incoming signal counting circuit CNT5 is counted-up and by a first receiving number of times value of the incoming signal to be set in advance, B relay 6 is activated and the sound volume of the bell 4 is caused to be large. Further, when the sound receiving number value of the incoming signal to be set in advance is passed, a C relay 7 is activated and the sound volume of the bell 4 is allowed to be large further.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone set, and more particularly to a telephone set having a ring tone volume setting circuit.

[Conventional technology]

Conventionally, this type of telephone has a volume setting circuit that outputs a set volume at which the volume of a ringtone is adjusted in advance when a call arrives.

[Problem that the invention seeks to solve]

With the conventional telephones mentioned above, even if you can set the ringtone volume, the volume is fixed. Depending on the setting conditions (or the indoor environment conditions at the time of receiving a call on the M call side), the ringtone may be too high and harsh on the ears. If the size is manually adjusted, the disadvantage is that the ringtone may be too low to be heard by someone who is far away from the room where the phone is installed.

[+ steps to solve problem t']

The telephone of the present invention includes an incoming signal detection circuit that detects an incoming signal, an incoming call number 15 counting circuit that counts the number of received strokes of the incoming call signal, and an incoming call volume that automatically adjusts the incoming call volume based on the count signal of the incoming call number 1G counting circuit. It has a volume control circuit and 1-.

[Tentative implementation IJ] Next, an uninvented embodiment will be described with reference to the drawings.

FIG. 1 is a circuit diagram showing one embodiment of the present invention.

In FIG. 1, the telephone of this embodiment has a capacitor C, a resistor R, an incoming call volume adjustment circuit 2, and a bell 4 connected in series between the input terminals connected to the telephone line and L. or,
Input terminal L1. Between L and hook switch (hereinafter referred to as H8) 8t e 8z Transmitter (hereinafter referred to as T) 9
and the receiver (hereinafter referred to as C) 10 are connected in parallel,
An incoming signal detection circuit 1 is connected with both ends of the resistance ratio as input terminals, and the number of signals in the n layers is detected by the incoming signal detection circuit 1.2. Relay (hereinafter referred to as A IJ relay) 3 temporarily contacts the incoming signal detection circuit 1, and when the A IJ relay is driven, the number of connections of A relay 3 and the number of ons of J and ra is determined. Counting arrival 1N signal counting circuit (hereinafter referred to as CNT) 5
Two incoming call volume adjustment relays (hereinafter referred to as B relay and C relay, respectively) 6 are driven according to the count of CNT 5.
．． 7 is connected to the clear terminal of CNT5, and H8F33 is connected to the clear terminal of CNT5.
Contact r of B relay 6 connected to both ends of 22, and R12
Contact r of the C relay connected between one end of 1 and R, 222 no 4. It is composed of:

The operation of this embodiment after the arrival of an incoming call signal will now be explained.

Furthermore, when an incoming signal input from the telephone line (9) arrives at the input terminal Ll*L2, the bell 4 makes a ringing sound, and the incoming signal detection circuit 1 detects the signal and sends it to the A relay 3.
The contact RA is activated and remains open for 1 second while the incoming signal is present.

First, the B relay 6 is activated according to the first reception count value (=-1) of the incoming signal that is counted up and set in advance. The operation of relay B closes the HIJ relay contact rb in the incoming call volume adjustment circuit 2, and the input terminal L
The current value of the incoming signal from 1 becomes larger, and the sound of the bell 4 becomes louder. Furthermore, when the preset second reception count value (work time) of the N-other signal has elapsed, the C relay 7 is activated, and the contact r0 of the C relay of the incoming call volume adjustment circuit 2 is closed in the same way, and the result is The sound of bell 4 becomes even louder.

As mentioned above, in this embodiment, the first ringtone is low;
After a preset time has elapsed, the sound will ring loudly, and then the 7&i-tone will be automatically adjusted in three stages so that it will ring even louder.

〔Effect of the invention〕

As explained above, the present invention has the advantage of fully automatically adjusting the number of times a ringtone is received by a counting circuit for N and other signals, and the number of times a danger 16 signal is received for a person near the telephone. Since it responds in a relatively small amount of time, the loudness of the 1g sound is completely eliminated, and the blasphemy volume at a long distance from the phone becomes high after receiving an incoming signal 6 times. It has the effect of eliminating the inconvenience of not being able to hear the ringtone by 9%.
