Patent ID: 7625213

Claim:
Magnetic means for detachably and rotatably connecting components in an audio speaker system which comprises a transmitter module securely disposed in a power and/or signal source of the audio system and a corresponding receiver module securely disposed in a power and/or signal receiving means of the audio system, each of the transmitter module and the receiver module comprises a ring-shaped magnetic body with a front wall, a rear wall, an outer wall and an inner wall; a first electrically insulated layer surrounding the inner wall of the magnetic body; a conductive pin passing through the first electrically insulated layer with a rear end electrically connected to a power and/or signal circuit; a conductive plate which connects to the rear wall of the magnetic body and is disposed in an electrically insulated manner from the conductive pin, and a rear end of the conductive plate is electrically connected to a power and/or signal circuit; a second magnetically insulated layer having an insulated outer wall and an insulated inner wall, and the insulated inner wall surrounds the outer wall of the magnetic body; and a bracket which is electrically and magnetically conductive and surrounds the insulated outer wall of the second magnetically insulated layer and connected to the conductive plate, and the bracket is magnetically insulated from the front wall and the outer wall of the magnetic body; wherein the transmitter module has a first polarity at the front wall of the magnetic body thereof and a second polarity opposite to the first polarity at a front end of the bracket thereof, and the receiver module has the second polarity at the front wall of the magnetic body thereof and the first polarity at a front end of the bracket thereof, and the magnetic body and the bracket of the transmitter module have the same diameter as those of the receiver module, so that when the power and/or signal source is activated and the receiver module is connected to the transmitter module, the magnetic bodies and the brackets of transmitter module and the receiver module are rotatably attracted and connected to each other and power and/or signal is transmitted from the transmitter module to the receiver module via the conductive plates and the brackets thereof, and the conductive pins of the transmitter module and the receiver module connect with each other so that power and/or signal is transmitted from the transmitter module to the receiver module.
