DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone terminal connected to a public line.

[0002]

2. Description of the Related Art In recent years, as a service of a telephone exchange, there is a caller telephone number service for transmitting telephone number data of a caller on a call signal.

FIG. 2 is a block diagram showing a configuration of a conventional telephone terminal device having a function of adjusting a reception sound volume. Reference numeral 1 denotes a main unit.
_1, L ₂ are connected. Interface unit 2閉結DC loop office line L _1, L _2, opening the conducted or from the office line L _1, L _2, detects the calling number by the calling party telephone number service described above.

A transmission power amplifier 3 is connected to a microphone 5 of a handset 4. Reference numeral 6 denotes a receiving sound volume level adjusting unit, which adjusts the sound volume level of the audio signal input from the office lines L ₁ and L ₂ via the interface unit 2 by manually operating the receiving sound volume level operating unit 7. A receiving power level amplifying unit 8 amplifies the power of the receiving signal input from the receiving sound volume level adjusting unit 6 and inputs the amplified signal to the speaker 9 of the transmitter / receiver 4.

[0005] The conventional telephone terminal device is configured as described above, and the receiver manually adjusts the reception sound volume level operation unit 7 as necessary to adjust the reception sound volume.

[0006] The received voice level input from the office lines L ₁ and L ₂ may have a low call input level from a remote place even if the input / output level is adjusted in the exchange. There is.

[0007]

Therefore, in a conventional telephone terminal device, for example, when a received voice level is low in a call with a remote place, the received voice level is increased by manually operating the received sound volume level operation unit 7. When the next call was a short-distance call, the input level was high on the contrary, and the level had to be lowered again by manual operation.

That is, the conventional telephone terminal device often manually adjusts the receiving sound volume level every time a call is made.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a telephone terminal device which does not have to be used to adjust the volume level every time a call is made as described above.

[0010]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a receiving sound volume level adjusting means for adjusting a receiving sound volume level.
To detect the caller telephone number sent from the exchange
Call to store the caller's telephone number detected
Double and person number storage means, the part of the local number in the phone number
Area number storage means capable of storing numbers,
And a received sound volume level storage means for storing the received sound volume level information necessary for the call in association with the area code stored in stages, the calling by detecting the caller telephone number from the incoming signal
The area number information is read from the stored calling party telephone number and compared with the area number registered in the area number storage means. As a result, if there is a matching area number, Volume level corresponding to the area code
Reading the bell information from the reception volume level storage means ,
The volume level information is output to the reception volume level adjusting means.
This is achieved by configuring to forcefully adjust the received volume level .

[0011]

According to the above means, the area number of the call is determined from the telephone number of the incoming call, and the received volume level storage means storing the volume level information corresponding to the area number corresponds to the determined area number. The read volume level information is read out,
Based on the information, the level of the received voice is automatically adjusted.

[0012]

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

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In order to facilitate the description, FIG. 1 shows a calling party telephone number (A) and an area number to which the telephone number is assigned. (B), and the received sound volume level information will be described as (C).

In FIG. 1, members corresponding to those described with reference to FIG. 2 are denoted by the same reference numerals.
6 'has a combination of manual adjustment, earpiece volume level control of the electronic control, 10 telephone number of the called telephone input through the office line L _1, L ₂ from the exchange, in other words the calling party telephone number ( A)
Is detected by the interface unit 2 and stored, and 11 is an area number storage unit. The area number storage unit 11 registers the area number (B) by the area number storage operation unit 12. The area code uses the telephone number of the telephone number. Reference numeral 13 denotes a reception voice level storage unit, which stores volume level information (C) necessary for controlling the volume level of the reception volume level adjustment unit 6 ′ in a plurality of area numbers (B) stored in the area number storage unit 11. Each is stored in a one-to-one correspondence with, for example, the area code (B) for the caller telephone number (A)
It is assumed that the sound volume level information (C) is used for.

This embodiment is configured as described above.
Assuming that there is an incoming call accompanied by the caller number (A), the processing flow is as follows. First, the interface unit 2 that has detected the incoming signal detects the caller telephone number (A) transmitted at the same time,
It is stored in the caller number storage unit 10, and the stored telephone number of the caller telephone number (A) is compared with the area code (B) registered in the area number storage unit 11, and as a result, If there is matching registration information (area number), the volume level information (C) corresponding to the area number (B) is read from the receiving voice level storage unit 13 and is output to the receiving volume level adjusting unit 6 '. hand,
Automatically adjust the reception volume level.

That is, a suitable telephone call can be made by the volume level information (C).

In the above, the received sound volume level adjusting unit 6 'is configured so that the sound volume level can be adjusted by manual operation of the received sound volume level operating unit 7, and the sound volume in the received sound volume level storage unit 13 is operated by the operation. The level information (C) is also updated. Note that the received voice level storage unit 13
Is updated to the above-mentioned updated level.

[0018]

As described above, according to the present invention, when an incoming call is received from a station providing a caller number transmission service, the area code information is read from the caller telephone number and the reception voice level is obtained. The volume level information corresponding to the area code information is read from the storage unit, and it is possible to make a telephone call with the volume based on the volume level information. it can.
