Description

Telephone for Internet Phones {Telephone for Internet-phone}

The present invention relates to a telephone, and more particularly, to a telephone for an internet phone incorporating a sound card.

An Internet phone is a device or software provided to a client side in an Internet telephone call. Internet phone is a client program for Internet phone developed to run in Windows environment. It can make a voice call with a regular telephone through the ITSP in the receiving city through the Internet, and it can also add and receive video transmission. By using such an Internet phone, the user can make a telephone call with the other country in the foreign country having a terminal at an extremely low cost.

The Internet phone user must have a terminal such as a personal computer capable of internet, and the terminal must be equipped with a voice reproducing circuit, so-called 'sound card', for converting digital voice signals transmitted through the Internet into analog signals. do. The sound card outputs the converted signal to the speaker so that the user can hear the voice. In addition, the sound card converts the external voice into a digital signal through a microphone and converts the data into an external system for transmission or processing.

On the other hand, multimedia personal computers, which are widely used in recent years, have a sound card. This means that the utilization of the sound card is increased as much, and when another signal is input from the external system to the sound card when the Internet phone is used, signal interference occurs. This is often the cause of poor currency. In addition, when using an inner phone, there is a problem that a voice signal having a different route cannot be accepted.

The purpose of the present invention for the above problems, to provide a telephone that can make a telephone call over the Internet with clearer sound without interference from the outside. In addition, the present invention has an object to provide a telephone that allows the real-time use of a sound card installed in a computer even when using the Internet phone.

FIG. 2 shows the structure of a terminal section of the telephone for Internet phone of FIG.

The above object is a main body in which a sound card including an audio signal input / output unit for external microphones and speakers, a data input / output port for exchanging data by connecting to a terminal such as a PC capable of Internet phones, and a voice data processing circuit. ; A handset containing a microphone and a speaker connected to the voice signal input / output unit; By including a cradle (Cradle) is installed in the main body so that the handset can be coupled to the main body, by using the handset achieved by the phone for the Internet phone, characterized in that the phone call using the Internet do.

According to a feature of the present invention, the main body has an ON / OFF switch installed on the cradle. Here, the on-off switch automatically connects to and releases from an Internet site providing an Internet phone service according to its operation.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. 1 is a perspective view of a telephone for an Internet phone according to the present invention. FIG. 2 shows the structure of a terminal section of the telephone for Internet phone of FIG. 3 is a state diagram used in connection with a PC.

The appearance is almost the same as a regular phone except for the key button for entering a phone number. That is, the handset 2, the handset on which the handset is mounted, the circuit 4 and the like are installed, the cradle 6 is installed on the body, although not shown is installed on the cradle, the handset is automatically placed on or off Consists of a button-type switch operated by a button. One side of the main body 4 is provided with a terminal portion 8 for exchanging signals with an external system. The appearance of the telephone as shown can be variously changed as required.

The main body incorporates a sound signal reproducing circuit, a so-called sound card 10, therein. The sound card used in the present invention is not much different from that of the general. The sound card has a terminal section for input and output of an external signal. As shown in FIG. 2, the terminal portion 8 is composed of a data input / output port 12, a microphone terminal 14, and a speaker terminal 16. The data input / output port 12 allows a voice signal processing circuit, that is, a sound card, to connect with a terminal 18 (see FIG. 3) such as a PC or a notebook to exchange data with each other. According to the present embodiment, the data input / output port uses a format applied to an interface such as USB (Universal Serial Bus) provided in Windows 98 provided by Microsoft Corporation.

USB is a serial port released with Windows 98. It is a Plug and Play (PnP) interface between a computer and peripherals such as joysticks, keyboards, phones, scanners, and printers. Therefore, in addition to this format, other interfaces of similar functions that have been used previously can be used.

The handset 2 may be coupled to the cradle 6 of the main body, and incorporates a speaker and a microphone, and exchanges an analog voice signal with a sound card of the main body. The handset is connected to the main body (more specifically, the input / output unit of the sound card) through the elastic cord 20. The main body is provided with a terminal (not shown) having the same shape as a terminal provided on the bottom or side of the main body of a general telephone on the bottom or side.

The switch operated on or off depending on whether the handset is coupled is for connection and disconnection between an Internet site providing an Internet phone service and a user terminal. According to this, the user's terminal is automatically connected to the Internet site by lifting the handset from the cradle, and automatically released when it is released. This is similar to the cradle switch of a regular telephone.

Through the microphone terminal 14 opened to the outside of the main body can receive a voice signal output from an external system such as a microphone and transmit it to the user terminal. In addition, the speaker terminal 16 enables output of audio signals to amplifiers and other systems. In other words, these functions are the same as the existing sound card, so detailed description thereof will be omitted.

The present invention is based on the use of the phone for the Internet by embedding a sound card in the phone. Those skilled in the art can make various changes or additions to the phone of the embodiment for this purpose, but it is within the scope of the technical idea of the present invention.

According to the above configuration, since the Internet phone user uses a sound card dedicated to the Internet phone, the user can make a call with clean sound quality without receiving any interference from the outside when using the Internet phone. In addition, in the way of use, it is similar to the way of using a regular phone, so it is possible to conveniently implement the Internet phone.
