Abstract

The subject invention relates to a type of multi-functional audio & video control box, comprising such components as an antimagnetic speaker box and several sets of audio/video selector whereby an audio/video connection switch box and an audio input/output speaker switch functions are completely integrated inside an antimagnetic speaker box, so as to very efficiently save space, with possible designing and combination of easily operated switches.

Claims

1. A multi-functional audio and video control device, comprising:

a speaker set having a plurality of speakers each having a magnetically shielded main body;

said magnetically shielded main body connected with a first momentary push button switch to select said speaker for audio input/output;

a common node of said first momentary push button connected to a normally closed node, a normally open node thereof being connected to an output of an audio amplifier and a lead of said magnetically shielded main body;

the output of said audio amplifier being connected to a second momentary push button switch for audio/video signal input/output selection, a common node of said second momentary push button switch being connected to said normally closed node;

at least one audio/video converter arranged within said magnetically shielded main body, each said audio/video converter having;

an audio input selection switch connected to the normally open node of said first momentary push button switch;

an audio output selection switch connected to the common node of said first momentary push button switch;

an A/V input selection switch connected to the normally open node of said second momentary push button switch;

an A/V output selection switch connected to the common node of said second momentary push button switch.

2. The multi-functional audio and video control device as in claim 1, wherein said first momentary push button switch has a plurality of switches.

3. The multi-functional audio and video control device as in claim 1, wherein said second momentary push button switch has a plurality of switches.

4. The multi-functional audio and video control device as in claim 1, wherein said audio input selection switch has a plurality of switches.

5. The multi-functional audio and video control device as in claim 1, wherein said audio output selection switch has a plurality of switches.

6. The multi-functional audio and video control device as in claim 1, wherein said A/V input selection switch has a plurality of switches.

7. The multi-functional audio and video control device as in claim 1, wherein said A/V output selection switch has a plurality of switches.

8. The multi-functional audio and video control device as in claim 1, further comprising an audio amplifier having an output connected to said magnetically shielded main body through said first momentary push button switch.

9. The multi-functional audio and video control device as in claim 1, further comprising means for signal switching and distribution arranged in an unused space of said magnetically shielded main body.

10. The multi-functional audio and video control device as in claim 9, wherein said means for signal switching and distribution are used for a plurality of telephone lines, a plurality of microphones and computer data switch/distribution.
