JPS61212944A - Calling device for telephone set - Google Patents

Abstract

PURPOSE:To inform the presence of an incoming call suitably to a called party by decreasing at first the sound volume of a call tone of a telephone set and increasing gradually afterward. CONSTITUTION:When a bell signal is incoming from a subscriber line L to an incoming detection circuit 1, an oscillation circuit drive signal is fed to an outgoing circuit 2. The call signal from the circuit 2 is outputted to a sounding body 4 via a sound volume control circuit 3. In this case, the circuit 3 uses an incoming start signal from the circuit 1 to increase stepwise automatically the sound volume of the sounding body 4. When a bell signal is stopped, it is detected by a bell signal stop detection circuit 5 and a reset signal is outputted to the circuit 3. The circuit 3 is reset by using the reset signal from the minimum sound volume at the next incoming call. Thus, the presence of the incoming call is informed surely to the called party.

Description

[Detailed description of the invention] [Field of application of the invention] The present invention automatically adjusts the ring tone of the telephone in stages.

Incoming call, to the called party, by increasing the.

The present invention relates to a telephone paging device that can accurately notify of certain events.

[Background of the invention]

Conventionally, the volume of a telephone paging device is fixed, so depending on the surrounding circumstances, it may not be possible to notify the called party of an incoming call.

Ta.

Also, for such cases, for example, Jikoaki.

Switch the volume as described in Japanese Patent No. 57-5955.

There is a paging device that has a mechanism for reading, but this one does.

The volume can be changed depending on the surrounding situation.

The disadvantage was that it had to be done. .

[Purpose of the invention]

The purpose of the present invention is to eliminate the drawbacks of the above-mentioned prior art.

This makes it possible to accurately transmit the ringing tone of the telephone to the called party, thereby notifying the called party of an incoming call within 1°.

To provide a telephone calling device. .

[Summary of the invention]

To achieve this objective, the present invention provides a telephone.

For the called party, the volume of the machine's ringer is initially lowered and then increased five steps later.

This enables accurate notification of incoming calls.

It is distinctive in that it did so.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

The figure shows an example of a telephone calling device according to the present invention.

This is a block diagram showing the ground side, and 1 indicates incoming call detection.

2 is an oscillation circuit, 6 is a volume control circuit, and 4 is a circuit.

A sounding body, 5 is a bell signal stop detection circuit, and L is an addition.

This is the personal line.

In the same figure, the incoming call detection circuit from the subscriber line.

When a bell signal enters the oscillator circuit 2,

Oscillation circuit drive signal while the bell signal is input.

signal is applied. With this oscillation circuit drive signal.

Oscillation circuit 2 is driven and called from oscillation circuit 2.

The signal is output to the sounding unit 4 via the volume control circuit 3.

It will be done. At this time, the volume control circuit 3 serves as an incoming call detection port.

In response to the incoming call start signal from Route 1, the volume of sounding element 4° is automatically increased step by step. When the bell signal stops, the bell signal stop detection circuit 5 detects this and outputs a reset signal to the volume control circuit 3.

This reset signal causes the volume control circuit 3 to be reset so that the next time a call is received, it starts from the minimum volume.

In this way, when you receive a call, the volume is always low.

The ringtone starts at 1 and gradually decreases in volume until the caller is connected or the caller hangs up.

It can be made larger.

〔Effect of the invention〕

As explained above, according to the present invention, the surroundings.

is in a noisy situation or the called party is on a telephone.

Even if you are far away, the ringtone will ring every time.

There is no need to change the amount of acupuncture, and the acupuncture needle is targeted to the called person.

The above can notify you that there is an incoming call.

A phone with excellent features except for the shortcomings of the prior art.

A paging device can be provided.

[Brief explanation of the drawing]

Incoming call detection circuit, 2... Oscillation circuit, 3... Volume control circuit, 4... Sound generating body, 5... Bell signal stop detection circuit.

Claims (1)

[Claims] It consists of a detection circuit that detects the arrival of a bell signal, an oscillation circuit that starts oscillation based on the detection output of the detection circuit, and a volume control circuit that gradually increases the amplitude of the output signal of the oscillation circuit. 1. A telephone ringing device characterized in that the volume of a ringing tone can be gradually increased by supplying an output signal to a sounding body.
