Description

Wireless sound transfer and receiver card for computer

The present invention relates to a wireless sound transmission and reception card for a computer, and more particularly, it is possible to transmit and receive sound without connecting a cable between two or more computers, and to temporarily store a portion of the sound and repeat it more than once. A wireless sound transmission and reception card for a computer that enables playback.

In a conventional computer, a sound card is built in so that various types of information can be heard not only by text but also by sound. In particular, by imposing a two-way communication function to the sound card used in the office or academy, there is an advantage that the dialogue between the staff, the student and the teacher or the multiple conversation between the student and the student is possible.

Two-way communication between two or more computers up to now, each computer must be connected with a separate cable, so there is a drawback, such as rising construction costs and occupy a lot of space.

The present invention is to provide a wireless sound transmission and reception card for a computer that can transmit and receive sound without connecting a separate cable between two or more computers, and to temporarily store a part of the sound and to play it repeatedly one or more times. For that purpose.

Hereinafter, a preferred embodiment of the present invention will be described in more detail with an exemplary drawing.

Referring to FIG. 1, the present invention is a wireless receiving circuit unit 1 for receiving a radio transmitted from another computer and inputting it to an amplifying circuit unit 6, 7, the wireless receiving circuit unit 1, and a microphone jack 2. Amplifying circuit section 6 (7) for first amplifying the sound input from the microphone inserted into the (3), and the first amplified sound and the external input terminal (8) from the amplifying circuit section (6) (7). Amplifying circuit section 9 (10) for amplifying the sound input through the secondary and outputting to headphones connected to the wireless transmission circuit section 12, the speaker 13, the external output terminal 14, and the headphone jacks 15 and 16. And the sound output from the amplifying circuit section 9, 10 under the control of the computer CPU 4, and temporarily recording the sound output from the amplifying circuit section 9 and 10 repeatedly and feeding it back to the amplifying circuit section 6 and 7. To control the overall driving of the wireless sound transmission / reception card by an external input or embedded program A computer CPU 4 and a wireless transmission circuit section 12 for converting the sound output from the amplifying circuit sections 9 and 10 into radio signals for radio transmission and transmitting them wirelessly to another computer.

In addition, according to the present invention, the switch (S1) for switching the sound input to the amplification circuit section (6) (7) from the wireless receiving circuit section 1, and the wireless transmission circuit section (a) in the amplification circuit section (9) (10) 12) or a switch (S2) (S3) for switching the sound output to the speaker 13, and a switch for switching the sound fed back from the amplifying circuit section (9) (10) to the recording / reproducing IC (11) (S4) and the like, and the switches S1 to S4 are 'on / off' by the computer CPU 4 driven by an external input such as a keyboard or a mouse or a program mounted therein.

In the present invention configured as described above, the amplification circuit section 6, 7 includes sound collected by a microphone connected to the microphone jack 2 or 3 through which sound transmitted wirelessly from another computer is input through the wireless receiving circuit section 1. Will be entered. At this time, the sound transmitted wirelessly from another computer is selective to the amplifying circuit unit 6 and 7 as the switch S1 is switched to an 'on / off' state under the control of the computer CPU 4 through the interface unit 5. Will be entered.

The first amplified sound in the amplifying circuit unit 6 and 7 and the sound input from the external input terminal 8 are amplified again in the amplifying circuit unit 9 and 10 and wirelessly connected through the wireless transmitting circuit unit 12. It is selectively output to headphones connected to another computer or speaker 13, external output terminal 14, headphone jacks 15 and 16.

Here, the switches S2 and S3 for selectively connecting the amplifying circuit sections 9 and 10 to the wireless transmission circuit section 12 and the speaker 13 are connected to the computer CPU 4 via the interface section 5. The control, that is, switched on or off by an external input such as a keyboard or a mouse or a program mounted in a computer, determines the output path of the sound output of the amplifying circuit unit 9 (10).

In other words, as the switches S1, S2, and S3 are switched 'on / off' under the control of the computer CPU 4, the sound transmitted wirelessly from another computer is transmitted to the speaker 13 or the external output terminal ( 14) or the sound collected by the microphone connected to the headphone jacks 15 and 16 and collected by the microphone connected to the microphone jacks 2 and 3 is wirelessly transmitted to another computer through the wireless transmission circuit unit 12. Will be.

Next, when the recording, recording interval, and the number of times of reproduction are set by the operation of the mouse or the keyboard, the switch S4 is switched to the 'on' state under the control of the computer CPU 4, and the amplification circuit unit 9 (10) The sound outputted from the C1) is fed back and recorded in the recording / reproducing IC 11.

Then, the recorded sound is reproduced again and first amplified in the amplifying circuit section 6, 7, second amplified in the amplifying circuit section 9, 10, and then another computer connected wirelessly to the wireless transmitting circuit section 12 or the like. It is selectively output to the headphones connected to the speaker 13, the external output terminal 14, and the headphone jacks 15 and 16.

Of course, the recording period or the number of times of the recorded sound as described above can be naturally set by the user.

Therefore, according to the present invention, two or more computers are separately cabled by wirelessly transmitting and receiving a sound transmitted and received between two or more computers, and temporarily storing a part of the sound and repeatedly playing it one or more times. You can send and receive sounds without connecting them, and you can hear the necessary sounds repeatedly.

Although the present invention has been described in detail only with respect to the embodiments described, it will be apparent to those skilled in the art that various modifications and changes are possible within the technical idea of the present invention, and such modifications and modifications belong to the appended utility model registration claims. will be.
