Abstract

PURPOSE:To prevent the sound volume of a tone ringer from becoming excessively large in a usual condition, and besides, to facilitate the hearing of a ringing tone even if a callee is comparatively distant from a telephone set or is sleeping. CONSTITUTION:A detecting part 1 detects the ringing tone by the ringing of the tone ringer 6. The number of the ringing of the ringing tone detected by the detecting part 1 is counted by a ringing tone counting part 2. A controlling and processing part 4 supervises the counting of the number of times of the ringing tone at the ringing tone counting part 2, and every time it counts some definite number, it gives an instruction to increase stepwise the amplification degree of the sound volume to a ringing tone sound volume amplifying part 3. The sound volume of the ringing tone is increased by the operation of the ringing tone sound volume amplifying part 3. When a stop switch 5 is turned on by manual operation, the detecting part 1 does not detect the ringing tone even if the ringing tone rings, and the sound volume of the ringing tone is not increased.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone, and more particularly to a telephone which can change the volume of a ringing tone when an incoming call arrives.

[0002]

2. Description of the Related Art In conventional telephones, the volume of the ringing tone when an incoming call is set is fixed or the level is set by manual operation of the volume, and is automatically changed while the tone ringer is ringing. It was a constant volume that was not played.

[0003]

The ringing volume of the conventional telephone is fixedly set so that a person can listen to the telephone relatively close to the place where the telephone is installed and the noise is not excessive. As a result, people who are a little far from the phone, who are separated by doors or walls, or who are in noisy surroundings may not hear the ringing tone and may not notice the incoming call. There is a drawback in that a person near the phone may feel uncomfortable due to the loud volume.

[0004]

The telephone of the present invention is a telephone having a tone ringer, and is provided with ringing volume varying means for gradually increasing the volume of the ringing tone that the tone ringer rings from the time of the incoming call until it is off-hook. I have it.

The ringing sound volume changing means detects a ringing sound from the tone ringer, a ringing sound counting unit for counting the number of ringing sounds of the ringing sound detected by the detecting unit, and this ringing sound. A ringing tone amplifying unit that increases the ringing volume each time the counting unit counts a predetermined number, and a control processing unit that controls the amplification degree of the ringing tone amplifying unit according to the count number from the ringing tone counting unit. And a stop switch for stopping the function of the ringing volume changing means.

[0006]

The present invention will be described below with reference to the drawings. FIG. 1 is a circuit block diagram showing an embodiment of a telephone of the present invention.

The telephone 12 of this embodiment is a tone ringer 6.
A conventional telephone having a dial circuit section 7, a call circuit section 8, a handset 9, a hook switch 10 and a telephone terminal 11 is provided with a detecting section 1, a ringing tone counting section 2, a ringing volume amplifying section 3, a control processing section 4 and a stop switch. It is configured by adding 5.

The detection unit 1 detects the ringing tone from the tone ringer 6, the ringing tone counting unit 2 counts the ringing of the detected ringing tone, and the ringing tone volume amplifying unit 3 increases the volume of the ringing tone. The control processing unit 4 controls the ringing tone counting unit 2 in stages after counting a certain number of ringing tones and then counting the amplification amount of the volume of the ringing volume amplification unit 3 every certain number of times.
After the ringing tone is stopped, a control process for restoring the ringing tone counting unit 2 and the ringing tone amplifying unit 3 is performed. The tone ringer 6 is a ringing circuit for a ringing tone, and the volume is increased by the operation of the ringing volume amplifying unit 3. When the ringing volume automatic variable is not necessary, the stop switch 5 is manually turned on to stop the ringing volume automatic changing function.

Next, the operation of this embodiment will be described.
When the ringing tone due to an incoming call rings at the tone ringer 6, the detecting unit 1 detects the ringing tone. The ringing tone count unit 2 counts the number of ringing tones detected by the detection unit 1.
The control processing unit 4 monitors the number of ringing tones in the ringing tone counting unit 2 after the detection unit 1 detects the ringing tone, and the volume of ringing to the ringing volume amplifying unit 3 is gradually increased every time a certain number is counted. Instruct to increase the amplification degree. The volume of the ringing tone is increased by the operation of the ringing volume amplification unit 3. For example, the ringer sounds at the initial volume until the ringing 5 times, 1.2 times the initial volume from the 6th ringing, 1.5 times as much as the 9th ringing, 12
The volume gradually increases from the first ringing to twice the initial volume.

After the ringing tone stops due to the called party response or the caller disconnection, the control processing unit 4 performs a control process for restoring the ringing tone counting unit 2 and the ringing sound volume amplifying unit 3.

If the stop switch 5 is manually turned on when the ringing volume automatic variable function is not required, the detecting unit 1 does not detect the ringing tone and does not increase the ringing volume. Further, if the called volume turns on the stop switch 5 while the ring volume amplification section 3 is operating and the volume is amplified during the incoming call, the control processing section 4 instructs the ring volume amplification section 3 to restore the amplification, The volume amplification unit 3 is restored and the volume of the ringing tone of the tone ringer 6 returns to the initial volume.

[0012]

As described above, according to the present invention, the volume of the ringing tone is increased stepwise after a certain number of ringing tones are counted, so that the tone ringer volume is not excessively increased during normal operation. Even if the called party is relatively far away from the telephone or is sleeping, it is easy to hear the ringing tone, so that there is an effect that it is not left without noticing the incoming call.
