Abstract

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, a first electrically insulated layer, a conductive pin, a conductive plate, a second magnetically insulated layer and a bracket, 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.

Claims

1. 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.

2. Magnetic means for detachably and rotatably connecting components in an audio speaker system as in claim 1, wherein a front end of the conductive pin of the receiver module is spring-loaded to movably protrude outward from the front wall of the magnetic body of the receiver module;

and a front end of the conductive pin of the transmitter module is securely disposed within the first electrically insulated layer of the transmitter module.

3. Magnetic means for detachably and rotatably connecting components in an audio speaker system as in claim 1, wherein the front end of the bracket extends inward towards the magnet so as to provide more surface area for magnetically connecting the transmitter module and the receiver module and concentrate the magnetic force at the front end of the bracket.

4. Magnetic means for detachably and rotatably connecting components in an audio speaker system as in claim 3, wherein the second magnetically insulated layers each has a front wall which extends inward towards the magnetic bodies to insulate inner surface of the front end of the bracket from the front wall of the magnetic body and hold the magnetic bodies in place and thereby preventing the magnetic bodies from colliding with each other when the transmitter module and the receiver module connect with each other.

5. Magnetic means for detachably and rotatably connecting components in an audio speaker system as in claim 1, wherein an electrically insulated casing is provided at a rear end of the conductive plate for encasing the conductive pin.

6. Magnetic means for detachably and rotatably connecting components in an audio speaker system as in claim 1, wherein the magnetic body is in form of a magnetic material.

7. Magnetic means for detachably and rotatably connecting components in an audio speaker system as in claim 1, wherein the magnetic body is in form of a ferrite.

8. Magnetic means for detachably and rotatably connecting components in an audio speaker system as in claim 1, wherein the magnetic body is in form of a neodymium-ferrite-boron magnet.

9. Magnetic means for detachably and rotatably connecting components in an audio speaker system as in claim 1, wherein the bracket is made of a ferrous material.

10. Magnetic means for detachably and rotatably connecting components in an audio speaker system as in claim 1, wherein the bracket is made of iron.
