And a switching unit for switching on / off the telephone line between the telephone line 20 and the trunk line 30, and the voice signal of the sender or the user's voice signal transmitted from the counterpart phone 30 through the interface circuit and the switching unit. It consists of a network circuit for signal processing.

That is, in the above configuration, when the ring signal transmitted from the trunk line 30 and sensed by the ring signal detecting unit is input to the tone generating unit, the ring signal is driven by the tone generating unit to be output as a predetermined ring tone through the speaker. . When the user hears the ringtone and receives the call, the user enters the off-hook state and sets the switching unit to the on state so that the user can make a phone call with the other party.

By the way, in the telephone 20 which consists of the above-mentioned structure, there exists a following problem. When the user makes a phone call with the other party, the network circuit unit performing the function of transmitting the voice signal from the other party to the user or transmitting the user's sound to the other party does not perform the function of amplifying and attenuating the voice signal according to the call situation. When a user changes the phone to someone or finds something while making a phone call with the other party, a large number of users cover the microphone of the handset 20-a and change the phone to another person or find an object. In addition, when the other party does not like or hear a sudden loud noise, users are unable to adjust the volume of the call according to the call situation, such as hiding or hiding the earpiece of the handset (20-a).

In order to solve this problem, although some devices have been developed that can amplify the call volume by connecting to the telephone and the existing phone 20 that can adjust the call volume in the phone itself, the phone call volume is the external battery (60) In order to amplify or attenuate the linear amplification (40) using a), it does not provide a function to separately control the transmission sound and the reception sound, and to block the transmission and reception sound separated from the amplification and attenuation. When amplifying the call volume, the amplification of the call volume is amplified together with the transmission sound, and a situation such as discomfort is transmitted by transmitting a high volume sound to the other party as it is.

Therefore, the present invention was created in view of the above problems, and in the situation where a telephone call is made with the other party, the function of controlling the call volume by amplifying or attenuating the transmission sound and the reception sound, and adding a function to block the transmission sound and the reception sound. The purpose is to provide better call quality.

Telephone call volume control device 10 according to the present invention for achieving the above object is used to amplify the voice signal amplification unit 40, amplifying the voice signal 50 and a voice signal amplification and reception sound The battery 60 for external power supply, the existing phone-compatible modular plug 70, modular jack (70-a) and the like is configured to include.

That is, according to the present invention having the above configuration, the user can make a call by adjusting the sound of the counterpart while talking on the phone with the user's desired volume, and separately from the reception sound control, The user can adjust the volume as much as the user wants and deliver it, and not only can amplify and attenuate the call volume by receiving and transmitting sound, but also cut off the transmission sound completely if the user's sound is not completely transmitted to the other party. If you do not want to hear the other party completely, you can block the incoming sound completely. In addition, according to the present invention, the apparatus main body 10 and the handset 20-a can be used by connecting the apparatus to all landline telephones 20 and key-phone telephones connected by the modular jacks 70 and 70-a.

Hereinafter, an embodiment according to the present invention will be described with reference to the drawings.

The modular jack 70-a and the plug 70 to be connected are all composed of four pins. In general, microphones are arranged at both ends of the pins, and earphone terminals are arranged at two inner terminals. In the case of the earphone terminal, the terminal connected to the main body of the phone 20 becomes an input terminal and amplifies or attenuates a voice signal and transmits the earphone to the earphone. In the case of a microphone, the terminal connected to the receiver is an input terminal, and processes the voice signal and transmits it to the main body of the telephone. .

In some products, the reception sound terminal and the transmission sound terminal may be changed. In the above case, if the user selects the situation by using the transmission sound-receiving sound selection switch 90, the transmission sound and the reception sound can be precisely adjusted. It doesn't matter at all.

Attenuating the voice signal based on the signals input to the signal input terminals of the microphone and the earphone is possible only with the call volume adjusting switch 100 or 110 without using the battery 60, and the signal is inputted from the signal input to the input terminal. Amplification is possible only with the battery 60. When the user does not replace the battery 60 at the end of life due to the above configuration, it is impossible to amplify the signal input to the reception sound and the transmission sound input terminal, but it is possible to attenuate it.
