Description

SOUND CARD OF COMPUTER INTERCHANGEABLE FOR PHONES AND INTERNET PHONES}

The present invention relates to a sound card of a computer that also functions as a telephone and an Internet phone. More specifically, the present invention relates to a switching circuit having a switching switch incorporating a telephone circuit in a computer sound card and electrically separating the sound card circuit and the telephone circuit. It is about a sound card of a computer that combines a telephone and an internet phone so that one can use both a telephone and an internet phone at the same time.

In general, in order to make a call with a remote party located in a remote place, there are largely classified into a case of using a general wired or wireless telephone and an internet phone.

Recently, due to the explosive increase in the number of computer users, the use of low-cost Internet phones is increasing rapidly, since international phone calls are very expensive.

'Internet phone' refers to the equipment or software provided to the client side to make a phone call through the Internet of the computer. When a computer user connects to an Internet phone provider via the Internet, the user can call the user's desired phone number. This is the name of the client program for Internet telephony, which allows you to make and receive calls using a computer sound card so that you can talk to the remote party by connecting to the Internet without using a regular telephone network. In the case of high-priced long-distance calls or international calls, the Internet phone is widely used due to the burden of the royalty.

In order to use the Internet phone, the user connects the earset to the sound card built into the main body of the computer or talks with the other party using a speaker and a microphone. The earset is formed by integrally forming a microphone and a speaker to transmit and receive. It is a device that can be placed on the user's head to talk to the other party.

Therefore, in the related art, in order to use an Internet phone, there is an inconvenience in using it by connecting an ear set separate from the ear set used in the phone to a computer sound card.

Since the reference voltage level and the magnitude of the resistance components of the sound card switching circuit and the phone switching circuit built in the computer for using the Internet phone are different, unwanted current flows when the phone and the Internet phone are directly connected. There was a problem that the call could not be connected cleanly because of severe noise in the earset.

In order to solve such a conventional problem, the present applicant solved the above problem by devising an earset common device for a telephone and an Internet phone, which is filed by the applicant of the present application No. 20-1999-0030051, Due to the various devices, the appearance is not beautiful and the surrounding area of the computer is complicated, resulting in inconvenience in use and management.

The present invention has been made to solve the above-mentioned conventional problems, and the noise generated by the difference of the reference voltage level and the resistance component by connecting a device having a transmission / reception function such as an earset to a sound card having a telephone circuit The purpose of the present invention is to provide a clear and convenient call and to provide ease of use and convenience when using the Internet phone and telephone.

In order to achieve the above object, a sound card circuit and a telephone circuit are respectively installed in a known sound card, and a telephone and an internet phone which have a switching circuit having a switching switch electrically separating the sound card circuit and the telephone circuit are combined. To provide a sound card.

Hereinafter, the configuration of the present invention with reference to the accompanying drawings in detail as follows.

Fig. 1 is a schematic diagram constructed by an embodiment of the present invention, and is a device in which a sound card circuit 11, a telephone circuit 12, and a switching circuit 13 are built in a sound card 10 of a computer 1; 2 is a block diagram of a sound card according to the present invention, which connects the sound card circuit 11 and the telephone circuit 12 to the switching circuit 13, and detects the operation of the hook button 22 by the sensor unit 15. ) To be electrically disconnected by the changeover switch 14 and connected to the ear set 30.

In order to use an internet phone and a telephone at the same time with one earset 30, a sound card circuit 11 and a telephone circuit 12 are installed in a known sound card 10, respectively, and electrically connected directly to each other. The noise is generated due to the difference between the reference voltage level of the switching circuit 13 and the switching circuit of the telephone and the magnitude of the resistance, thereby preventing the problem of noise. In order to solve the problems described above, the sound circuit 10 and the telephone circuit 12 can be completely separated from each other by incorporating the switching circuit 13 having the switching switch 14 in the sound card 10. It was.

The sound card 10 may be the same as the size of a conventional sound card or may vary somewhat in size due to the formation of the telephone circuit 12 and the switching circuit 13, but it is difficult to be installed in the main body of the computer 1. It is composed of missing sizes.

The telephone circuit 12 is connected to a general telephone line connected to the main body of the computer 1 so that when a telephone call comes out, a signal tone is output through a speaker. It was installed to replace using the numeric keys 21 on the keyboard.

A sound card circuit 11 and a telephone circuit 12 are connected to the switching circuit 13, and a switching switch 14 is formed so that the sound card circuit 11 or the telephone circuit 12 is selected according to a user's selection. It is electrically separated so as to be connected to a device having a transmission and reception function such as the earset 30 to solve the problem of noise caused by the different reference voltage level and the magnitude of the resistance (Impedance).

In addition, the switching circuit 13 detects the operation of the hook button 22 so that a switching sensor 14 is formed so that the switching switch 14 is electrically disconnected and connected to the sound card circuit 11 or the telephone circuit 12. .

The hook button 22 is installed at a predetermined position such as a keyboard or a computer for the user's convenience, and is connected to the sound card switching circuit so as to be electrically connected to the sound card circuit or the telephone circuit by the operation of the hook button. By separating and connecting, Internet phone or telephone can be used freely according to user's choice.

Looking at the operation process by the configuration of one embodiment of the present invention as described above are as follows.

In general, when the user uses the Internet phone or listens to the music by the sound card 10 and presses the hook button 22 at a predetermined position of the keyboard or the computer, the electrical connection with the sound card circuit 11 is cut off. The earset 13 is electrically connected to the telephone circuit 12 so that the user can make a telephone call.

In addition, in order to make a phone call while the ear set 30 is connected to the sound card 10, the ear button 30 is disconnected from the sound card circuit 11 by pressing the hook button 22, and the telephone circuit 12 and In the state to be connected to the desired phone number by using the numeric keys on the keyboard to make a phone call through the earset (30).

Therefore, as described above, it is a very useful design to enable a clear call without disturbing noise when simultaneously using a telephone and an internet phone with one earset. Various modifications and variations are possible without departing from the spirit and scope of the present invention and are not limited to the above-described embodiments and the accompanying drawings.

Sound card circuit or telephone circuit built in sound card is connected by earset with electrical separation so that you can make a call with clear sound quality without disturbing noise when using internet phone and telephone at the same time. It is easy to manage because it provides a simple computer peripheral.
