As shown in Fig. 1, a general computer system includes a computer main body 20, a monitor 10 for displaying data processed by the computer main body 20, a mouse 31 as a pointing device, and the computer. Essentially, a key board 30 for inputting data into the main body 20 is provided.

As other computer peripheral devices, speakers 71 and 72 for outputting audio signals output from a sound card provided in the computer main body 20 as voice signals through the connection jacks of the computer main body 20, and the computer. A microphone 73 for inputting an audio signal to the computer main body 20 through a connection jack of the main body 20, a modem 32 for connecting the computer main body 20 to an external telephone line for communication; There are printers 33 for printing the data processed by the computer main body 20.

Here, the monitor 10 is connected to the computer main body 20 by conventional connection means 11, such as a D-SUB or BNC video cable. Thus, the computer main body 20 synchronizes video signals, for example, video signals of red (R), green (G) and blue (B), to the monitor 10 via the connecting means 11. Provides all information signals necessary for signal and monitor driving. In addition, the monitor 11 provides the general information signal corresponding to the monitor driving result from the monitor 10 to the computer main body 20 through the connecting means 11.

On the other hand, the computer main body 20 is connected to the sound card provided therein, the speaker (71, 72) and the microphone 73 provided in a separate connection line for input and output of an audio signal.

That is, the audio signal generated by the sound card is output to the speakers 71 and 72 through the headphone jack after the volume, balance, or tone is adjusted. The microphone 73 is connected to the sound card through the microphone jack so that an audio signal is input to the sound card of the computer main body 20.

In this way, since a speaker and a microphone are provided as peripheral devices in the computer system, voice communication can be performed using a computer equipped with a high-speed Internet communication network.

However, the speaker and the microphone, which is a peripheral device of the conventional computer system, have the following problems.

First, as described above, for the voice communication, a speaker and a microphone must be separately provided, or a head cell with a microphone attached to the headphone must be put on the head or inserted into the ear to communicate, which makes the installation of peripheral devices complicated and inconvenient to use.

Second, since the speaker and the microphone must be provided separately, the purchase cost of peripheral devices increases.

Third, as described above, when voice communication is performed using a head cell, multiple voice communication cannot be performed using a single computer.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a complex computer external speaker device that can be used together with an external amplified speaker, which is one of computer peripheral devices, as a microphone function and a voice reception function.

It is micro-operated when used and connected to the input of the first amplifier by the switching section 6.

That is, the hybrid computer external speaker device of the present invention, as shown in Figs. 3 and 4, a speaker connector (1) and a microphone for connecting the two speakers (4, 5) and the speakers (4, 5) to a computer The connector 7 is provided, and the switching part 6 for selecting a microphone function or a speaker function is provided in the front of one speaker 4, for example. In addition, a volume adjusting section 8 for adjusting amplification gain, a power jack 9a for supplying power to the speaker, and a power indicator 9b for displaying the power are provided in the same manner as a general external speaker. .

The operation of the composite computer external speaker of the present invention configured as described above is as follows.

First, the user connects the speaker connector 1 and the microphone connector 7 to the speaker jack (headphone jack) and the microphone jack of the computer main body, respectively.

As described above, the mode desired by the user is set through the switching unit 6 in the state in which the compound computer external speaker of the present invention is connected. In other words, when you want to listen to the audio signal output from the computer, operate the switching unit 6 so that the terminal (b) and the terminal (c) of the switching unit 6 is connected, when switching to perform voice communication using the Internet The terminal (a) and the terminal (b) of the unit 6 is operated to be connected.

Therefore, when the user operates the switching unit 6 so that the terminal (b) and the terminal (c) are connected to listen to the audio signal, the audio signal output from the computer is the first and second amplifiers (2, 3) Amplified by and output as a voice signal through the first and second speakers (4, 5), respectively. At this time, the audio signal output from the first amplifier 2 is applied to the first speaker 4 and also to the microphone connector 7, but the microphone connector 7 and the first speaker 4 Due to the difference in impedance therebetween, no audio signal is output to the microphone connector 7.

In addition, when the user manipulates the switching unit 6 so that the terminal a and the terminal b are connected to each other for the purpose of voice communication using the Internet communication network, the first speaker 4 functions as a microphone. That is, the first speaker 4 converts the surrounding sound into an electric signal and outputs the electric sound signal, and the electric voice signal output from the first speaker 4 is transferred to the first amplifier through the switching unit 6 ( Amplified in 2) is input to the computer through the microphone connector (7). At this time, an audio signal output from the computer is input to the input terminal of the first amplifier 2 and an audio signal output from the first speaker 4 is input. However, due to the impedance of the speaker connector, the signal output from the computer is not amplified by the first amplifier 2, but the audio signal output from the first speaker 4 is amplified. Therefore, since the first speaker 4 functions as a microphone and the second speaker functions as a speaker, voice communication using the Internet can be performed without installing a separate peripheral device.
