Abstract

PURPOSE:To send a key operation confirming tone with the optimum sound volume in response to the operating state by decreasing the sound volume of the confirming tone generated from a receiver in the operation relating to the operation of a function button more than the sound volume of the confirming tone generated from the receiver in sending a dial signal by the operation of a dial button. CONSTITUTION:When the user operates a re-dial button 13 to re-dial a dial sent once, the state of a re-dial button 13 is read from an input terminal R of a control means 15. The control means 15 reads dial data stored in a memory 14 from an input/output terminal M. The control means 15 controls a dial signal generating circuit 6 to generate a dial signal corresponding to the read dial data from an output terminal D. Thus, the confirming tone of the re-dial signal sent to a telephone line after the operation of the re-dial button 13 is generated with a smaller sound volume in comparison with that of the confirming tone sent one by one digit by the dial button 12.

Description

DETAILED DESCRIPTION OF THE INVENTION 3. Detailed Description of the Invention Field of Industrial Application The present invention relates to a telephone set in which a key operation or an operation confirmation sound is generated from the receiver based on the key operation.

Conventional technology Conventionally, in so-called dial-in handset type telephones that have a dial operation section inside the handset,
In order to reduce the size and cost of the telephone, a confirmation sound is generated from the handset when the dial button or redial button is pressed, so that the user can confirm each step of the operation. It has become.

Problems to be Solved by the Invention In the above-mentioned types of telephones, dialing buttons and redialing buttons are provided inside the handset.
Since I can't hold the receiver to my ear when I press the buttons, I set the volume to a high level so that I can hear it even if I'm a little far away from the receiver. In the case of a dial button, the confirmation sound stops when the dial operation is completed, so there is no problem even if you immediately put the handset to your ear. The operation continues for a while, and the dial confirmation tone continues to occur for a while. By the way, when re-dialing, the user presses the re-dial button, then holds the receiver to his ear and the other party answers. Therefore, especially in telephones connected to tone lines, the user may be surprised or, in some cases had the problem that it could cause hearing damage.

The present invention has been made in view of the prior art described in "Yu", and it does not require the provision of a dedicated sounding body in addition to the handset for sending out the key operation confirmation sound. The purpose is to provide a telephone that can send out messages.

Means for Solving the Problems In order to achieve this object, the telephone of the present invention has a function button operation that continues a series of operations even after the operation is completed, and that a confirmation sound is also generated in connection with the above operations. The volume of the confirmation sound generating means is adjusted so that the confirmation sound sent from the handset in the case of an operation related to the operation is lower in volume than the confirmation sound generated by the handset when a dial signal is sent by operating a dial button. A control means is provided for controlling.

Function: With this configuration, it is possible to obtain the key operation confirmation sound at the optimum volume depending on the usage state of the telephone.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

14 is a memory for storing dial data for redialing; 15 is a control means for controlling the operation of the entire telephone; An input/output terminal M1 connected to the memory 14; an output terminal D1 connected to the dial signal generating circuit 6; an output terminal P1 connected to the transistor 10; an input terminal connected to the dial button 12; It is equipped with an input terminal R and is composed of a microcomputer. Note that the same numbers in FIG. 1 and FIG. 2 indicate the same components.

The operation of the telephone configured as described above will be explained below. When the handset is picked up from a stand (not shown) (off-hook), the hook switch 2 is turned on and the telephone line 1 is closed. Subsequently, when the user operates the dial button 12 to make a dial call, the state of the dial button 12 is read by the input terminal K of the control means 15. The control means 15 controls the dial signal generating circuit 6 from the output terminal so as to generate a dial (DTMF) signal corresponding to the operated dial button. The dial signal generated by the dial signal generating circuit 6 is applied to the input terminal PB of the transmitting/receiving circuit 3, amplified by the transmitting/receiving circuit 3, and sent to the telephone line 1. After that, the telephone receiver 5 generates a confirmation tone. At this time, the output terminal P of the control means 15 is at the logic level L#, and the collector-emitter of the transistor 10 is in an off state. At the same time, the dial data is stored in the memory 14 via the input/output terminal M of the control means 15. When dialing the required number of digits is completed and the other party is connected, a telephone conversation can be made using the transmitter 4, handset 5, and transmitting/receiving circuit 3.

When the call is over and the handset is placed on a stand (not shown), the hook switch 2 is turned off and the telephone line 1 is released.

Next, a redialing operation for calling a previously called party again will be explained. When the handset is picked up from a stand (not shown) (off-hook), the hook switch 2 is turned on and the telephone line 1 is closed. continue,
When the user operates the redial button 13 in an attempt to re-dialing a dial that has already been dialed, the redial button 1
3 is read from the input terminal R of the control means 15. The control means 15 reads dial data stored in the memory 14 from the input/output terminal M.

The control means 15 controls the dial signal generation circuit 6 from the output terminal so as to generate a dial (DTMF) signal corresponding to the read dial data. The dial signal generated by the dial signal generating circuit 6 is applied to the input terminal PB of the sending/receiving circuit 3, amplified by the sending/receiving circuit 3, and sent to the telephone line 1. At the same time, the dial signal generated in the dial signal generation circuit 6 is applied to the confirmation sound amplification circuit 11, but at this time, the output terminal P of the control means 15
is at a logic level H', and a control signal is applied to the base via the resistor 9, and the collector and
The area between the emitters is in an on state. Therefore, the signal generated by the dial signal generation circuit 6 is voltage-divided (attenuated) by the resistors 7 and 8 and applied to the confirmation sound amplification circuit 11 where it is amplified, and a confirmation sound with a reduced volume is generated from the receiver 5. do. Therefore, the confirmation sound of the redial signal sent to the telephone line after operating the redial button 13 is generated at a lower volume than the confirmation sound when the dial button 12 sends out one digit at a time. Here, even if the user puts the receiver to his ear immediately after operating the redial button 13, there will be no problem because the volume of the confirmation tone is not large.

Once connected to the other party, a conversation can be made using the transmitter 4, handset 5, and transmitting/receiving circuit 3. When the call is over and the handset is placed on a stand (not shown), the hook switch 2 is turned off and the telephone line 1 is released.

Effects of the Invention As described above, the present invention provides that the handset is activated when a series of operations continues for a certain period of time even after the operation is completed, and the confirmation sound is also generated in conjunction with the operation of a function button. A control means is provided for controlling the volume of the confirmation sound generating means so that the volume of the confirmation sound generated by the receiver is lower than the confirmation sound generated by the receiver when a dial signal is sent by operating the dial button, The key operation confirmation sound can be sent out at the optimal volume depending on the usage condition without the need for a special sounding device other than the receiver to send out the key operation confirmation sound, and its practical effects are great. be.
