Abstract

PURPOSE:To prevent a person from being surprised and a call tone from being missed by forming a device so as to increase the sound volume level of the call tone gradually from a low range to a high range. CONSTITUTION:A CI(call signal) detection circuit 2 and a ringer 3 are provided at an NCU(network control unit) 1, and when the circuit 2 detects the call signal, the ringer 3 is started up, and also, the detection informing signal (b) of the call signal is sent out to a control circuit 4. A bell signal (d) sent out from the ringer 3 is supplied to an amplifier 6 via a bell sound volume switching circuit 5, and furthermore, it is sent out to a speaker 7, then, it goes to sound. Meanwhile, the circuit 4, when receiving the signal (b), detects the presence/ absence of response by the on-hook state of a hook switch 8, and sends a sound volume increasing signal (c) to the circuit 5 and increases the sound volume level gradually as far as no response is issued.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a telephone ring tone generating device for generating a ring tone in a telephone set.

(Prior Art) In conventional devices of this type, the volume was manually adjusted using a switch. And on the phone, the third
As shown in the figure, the process from detection of a ringing signal (301) to off-hook and response (303, 304) to ringing the bell (02) was all that was required.

However, the volume adjusted with the switch remains constant. That is, if the volume level is set to low, there is a possibility that the user may miss the ringing sound, and if the volume level is set to high, the user may suddenly hear a loud ringing sound, which may cause discomfort.

(Problems to be Solved by the Invention) As described above, according to the conventional telephone ring tone generating device, although the volume can be adjusted with a switch, the volume remains constant after setting. For this reason, if the volume level is set to low, there is a possibility that the user may miss the ringing sound, and if the volume level is set to high, the user may suddenly hear a loud ringing sound, which may cause discomfort.

The present invention was made to solve the problems of the conventional telephone ringer, and the purpose is to prevent problems such as missing a sound without adjusting the volume or being surprised by a loud ringer. To provide a telephone ringing tone generator capable of making an appropriate call without any hassle.

2. Structure of the invention; (Means for solving the problem) Therefore, in the present invention, there is provided a ringing signal output means for detecting the arrival of a ringing signal and outputting a ringing signal, and a ringing signal output means for detecting the arrival of a ringing signal and outputting a ringing signal; a volume level increasing means for detecting whether there is a response, and gradually increasing the volume level of the ringing tone signal output from the ringing tone signal output means if there is no response; A telephone ringing tone generating device is constructed by comprising a ringing tone generating means for generating a ringing tone based on the telephone ringing tone.

(Function) According to the above configuration, since the volume level of the ringing tone gradually increases from a small range to a large range, there is no surprise, and there is no chance of missing the ringing tone.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of one embodiment of the present invention. In the figure, 1 indicates an NCU (network control unit), which is connected to a line 9. NCUI has CI (calling signal) detection times 12
When the CI detection circuit 2 detects a ringing signal, it activates the ringer 3 and also controls the control circuit 4.
A call signal detection notification signal (b) is sent to. ringer
The bell sound signal d sent out from the bell sound signal d is given to an amplifier 6 via a bell volume switching circuit 5, and further sent to a speaker 7, where it is converted into sound.

On the other hand, when the control circuit 4 receives the detection notification signal (b),
The presence or absence of a response is detected depending on whether the hook switch 8 is off-hook, and unless there is a response, a volume gradual increase signal (C) is sent to the bell volume switching circuit 5 to gradually increase the volume level.

Specifically, the bell volume switching circuit 5 can be configured with a variable gain amplifier, for example.

In the telephone ring tone generator configured as described above, the second
As shown in the figure, NCU1 detects the arrival of the paging signal (a) (201), and when detecting the arrival of the paging signal (a> at CI detection time #I2, a bell sound is generated from the ringer 3. The signal d is converted into e and f and is applied to the speaker 7, causing a bell to ring (202).

The volume level at this time is the minimum. Then, the control circuit 4 receives the detection notification signal (b) and performs off-hook detection (203>), and if it is not off-hook, detects whether the volume has been set to the maximum volume (205).If the volume is not the maximum volume, the bell volume switching circuit 3 Sends a volume gradual increase signal (c) to increase the volume (206).Then, the process returns to step 202 and continues the operation.If off-hook is detected during this time (206),
03), the process moves to a response operation (204) and the ringing of the bell is stopped. Note that when the volume level is gradually increased without a response and reaches the maximum value (205), the fi loud volume is maintained.

In the embodiment, a bell tone is used, but other ring tones such as music may be used. Also, the volume level may be adjusted and amplified using a single variable gain amplifier.

7. Effects of the Invention: As explained above, according to the present invention, the volume of the ringtone is gradually increased, so no adjustment is necessary, and there is no need to be surprised by a sudden loud ringtone. This eliminates problems such as missing calls.
