Description

Telephone support device of having internet phone adapter}

The present invention relates to a telephone stand, and more particularly, to a telephone stand equipped with an Internet phone adapter function that allows a general telephone to be connected to a public telephone network (PSTN) or used as an Internet phone.

In general, a telephone stand is for placing a telephone and is widely used for promotion. That is, the telephone stand is printed and distributed on the front of the logo or telephone number of the public relations company, such a conventional telephone stand was a degree of attaching additional mechanisms for the function of simply placing the phone or writing instruments.

In order to achieve the above object, the telephone stand of the present invention has a stepped portion and an inclined portion formed at the front thereof to display an operation mode, and a rear plated body for seating the telephone; and the body A built-in DTMF detector for detecting a specific DTMF signal when a button of the telephone is operated; A sound processor for converting the analog voice signal transmitted from the telephone into digital, converting the digital voice data into analog and transmitting the analog voice signal to the telephone, and transmitting and receiving voice data to and from the computer according to a predetermined communication protocol; And a switching means for connecting the telephone to the line connection jack to be connected to the telephone network, and then connecting the telephone to the sound processor when the control signal comes from the DTMF detector.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a state diagram using the telephone stand according to the present invention, the phone 120 is placed on the telephone stand 110 is shown.

Referring to FIG. 1, the telephone base 110 protrudes from the front to form a stepped portion and an inclined portion, and LED lamps 111, 112, and 113 for displaying an operation state are positioned on the inclined portion. The LED lamp on the front is ON lamp 111 to indicate the power-on state, VoIP lamp 112 to operate as an Internet phone, PSTN lamp to indicate that it is operating as a general telephone connected to a public telephone network ( 113). In addition, the phone 120 is prevented from flowing down by the stepped portion, and the rear surface of the telephone base 110 is provided with a connection jack as shown in FIG. 2. Referring to FIG. 2, the rear of the telephone base 110 has a speaker jack 114 for connecting a speaker, an ear / microphone 115 for connecting an ear headset, and a telephone connection jack 116 for connecting a telephone. , A line connecting jack 117 for connecting a telephone line, and a USB port 118 for connecting with a computer is installed.

In addition, the inside of the telephone base 110 has a circuit as shown in FIG. 3 so that a general telephone can be connected to a public telephone network or an internet network so that the general telephone can be used as an Internet phone.

Referring to Fig. 3, the telephone connection jack 116 is connected to a telephone placed on the telephone base. The DTMF detection unit 302 monitors a DTMF signal from the telephone to detect a specific key signal (e.g., a "*" key signal). When it is determined that the user requires the operation in the Internet phone mode, the relay 306 is controlled to connect the phone to the sound processor 304.

The relay 306 normally connects the telephone to the line side and then connects the telephone to the sound processor 304 when a control signal is received from the DTMF detector 302. The sound processor 304 converts the analog voice signal transmitted from the phone into digital data, packetizes it according to the USB communication protocol, and outputs the packet to the USB port 118. The digital data received through the USB port 118 is analog signal. Play it and pass it to your phone. In addition, the sound processor 304 provides a function of connecting the speaker output and the ear / microphone jack, and controls the LED (111, 112, 113) to display the operation state.

4 is an operation flowchart of a telephone stand according to the present invention.
