It is configured to include.

In addition, Figure 2 is a block diagram of a remote control voice call support personal computer (PC) for a voice call device using a remote control according to the present invention, an infrared signal receiver for receiving an infrared signal transmitted from the infrared signal transmitter 30 of FIG. 380; An analog / digital converter (hereinafter referred to as an `` A / D converter '') 330b for converting the received infrared signal into digital data; A signal combiner / separator 310 for separating and separating a signal to be transmitted and received with the wireless transceiver 200 of FIG. 1; A voice signal detector 320 which detects a voice signal by band demodulating the signal output from the signal combiner / separator 310 after the band pass; An A / D converter (330a) for converting the detected voice signal into digital data; A modem 350 which modulates data and transmits it in analog and demodulates the modulated signal; A serial-parallel element (SIO) 340 for transmitting and receiving serial data with the modem 350; A memory 301 in which voice data to be transmitted and received is temporarily stored; A digital / analog converter (hereinafter, referred to as a 'D / A converter') 360 for converting voice data received from a counterpart and stored in the memory 301 into an analog signal; A voice transmitter 370 for modulating the analog-converted signal after low pass filtering and outputting the modulated signal to the signal combiner / separator 310; And a central processing unit (CPU) 300 that controls the data flow between the components and the connection of the modem 350 and interprets remote control input keys from digital data through the A / D converter 330b. It is composed.

In the voice call apparatus using the remote control according to the present invention configured as described above, first, the battery (B) in the remote control is charged by receiving the input power through the charging circuit 10 to configure each component of the remote control (A). Power the element. In this case, the switch SW is opened so that power is not unnecessarily supplied to the wireless transceiver 200. In this state, when the user selects a preset key for opening a voice call with the other party through the keypad 20, the microcomputer 100 reads the data bit stream corresponding to the input key from the ROM. The power is supplied to the wireless transceiver 200 for voice transmission / reception by controlling the switch SW to be short-circuited at the same time as it is read by the 110 and transmitted to the infrared signal transmitter 30.

The infrared signal transmitter 30 transmits an infrared signal corresponding to the input data bit to the infrared signal receiver 80 in the PC.

The infrared signal receiving unit 380 receives an infrared signal, converts it into an electrical signal, and then formalizes the signal into the A / D converter 330b, and the A / D converter 330b receives the input signal. By converting the digital data into the central processing unit 300, the central processing unit 300 interprets the received data to recognize the voice call request.

When there is a voice call request, the CPU 300 switches the modem 350 to a dialable state by controlling the modem 350, and receives the destination number received and interpreted according to the above-described process. The modem 350 transmits the received destination number to establish a voice call with the desired counterpart.

As described above, when the user inputs a voice through the microphone Mic in the remote controller A, the amplifier 40 is amplified and the low pass filter 50 amplifies the amplified signal. Only the audible frequency band will pass. The audible signal passing through the low pass filter 50 is high frequency modulated by the modulator 55 and input to the signal combiner / separator 310 in the PC through the signal combiner / separator 60 and the antenna ANT1.

The signal combiner / separator 310 separates the received signal from the transmission signal and inputs the received signal to the voice signal detector 320, and the voice signal detector 320 passes only a reception band of the received signal and then passes the received signal. By demodulating and restoring the original audio signal, the A / D converter 330a converts the restored audio signal into digital data and temporarily stores it in the memory 301. While the voice data is stored, the CPU 300 reads the voice data in the memory 301 in a storage order and transmits the voice data to the modem 350 through the serial / parallel element 340. The 350 modulates the received data into an analog signal and transmits the received data to the counterpart PC. The counterpart PC recovers the received analog signal into digital data through a modem and outputs the audio data through a sound card.

On the other hand, the analog signal by the voice received from the counterpart through the modem 350 is converted into digital serial data and input to the serial-parallel element 340 and then converted into parallel data, the converted parallel data is the memory 301 is stored in the input order. The CPU 300 reads the voice data stored in the memory 301 in the order of storage and transmits the voice data to the D / A converter 360 to convert the voice data into an analog voice signal. The voice transmitter 370 Low-pass filtering the analog-converted voice signal to remove high-frequency noise, and then modulates the high-frequency noise and transmits it to the wireless transceiver 200 in the remote controller A through the signal combiner / separator 310 and the antenna ANT2. do.

The signal combiner / separator 60 in the remote controller A separates the received signal from the transmission signal and outputs the signal to the band pass filter 70, and the band pass filter 70 filters only the signals in the reception band. Amplified output by the amplifier (75). The amplified output signal is demodulated by the demodulator 80 into an original analog voice signal and then amplified by a current amplifier 85 to a signal having a current magnitude necessary for driving the speaker Sp. ), The user of the remote controller A listens to the voice transmitted by the opposite party, and the voice call with the opposite terminal is made through the remote controller.

The voice call apparatus using the remote control according to the present invention configured and operated as described above enables the user to perform a voice call with the opposite terminal through the remote control, even when the user is operating the PC at a predetermined distance from the PC. Not only can you make a voice call in a comfortable position on the spot without having to be close to the PC, but you can move freely while the call is being made, which makes the use of the PC very convenient.
