Cables are magnetically attracted to magnets in straps and other items such as electronic devices. The cables may contain signal lines to convey power and/or data. Magnetic material that is attracted to magnetic fields may be incorporated into the signal lines and/or other structures in the cables. The straps may have flexible magnets and/or other magnets extending along their lengths. The magnets of the straps create magnetic fields that attract the cables. Electronic devices may also have housings that contain magnets to attract the cables. Using magnetic attraction, cables can be removably attached to straps and other items during operation of an electronic device, thereby helping to prevent tangling of the cables.

A magnetic buckle device has a first base, an inserting component, a second base, a first component, and a second component. The inserting component can be inserted into the first base, which engages the inserting component. The first base and the second base can move or rotate with respect to each other, thereby converting the inserting component into the unbuckled state. The first and second components are respectively mounted on the second base and the inserting component. When the inserting component is close to an inserting component receiver of the first base, a magnetic attraction force is generated between the second component and the first component for drawing the inserting component to the inserting component receiver. When the inserting component is inserted completely, the magnetic attraction force auxiliary keeps the inserting component in the buckled state, so any additional buckling structure is not necessary.

A headset is described that utilizes magnetic frictional couplers. A coupler includes a first member having a first engagement surface and a second member having a second engagement surface disposed for relative positioning of the first and second members along a line of adjustment. One or more magnetic elements are arranged on the first and second members to establish a magnetic flux between the first engagement surface and the second engagement surface, and thereby establishing a frictional force tending to hold the relative positions of the first and second members. The magnetic flux varies as a function of relative position of the first and second members along the line of adjustment, and has peaks at a plurality of detent positions along the line of adjustment.

A dual-contact electro-permanent magnet (EPM) assembly of an information handling system may comprise a plurality of high-coercivity magnets situated on opposite ends of a low-coercivity magnet, a first EPM magnetic contact disposed between a first of the plurality of high-coercivity magnets and the low-coercivity magnet, and a second EPM magnetic contact disposed between a second of the plurality of high-coercivity magnets and the low-coercivity magnet. The low-coercivity magnet polarity may correlate to a direction of current pulse applied to an electrically conductive wire coiled around the low-coercivity magnet, and dependent upon the low-coercivity magnet polarity, the first EPM magnetic contact is capable of operating in an attractive magnetic state to attract a ferromagnetic contact of a peripheral device while the second EPM magnetic contact is magnetically neutral with respect to the ferromagnetic contact.

A magnetic closure device has two complementary magnetic closure elements. Each of the two complementary magnetic closure elements includes an elongated magnet carrier having a single direction of main extension, and a plurality of permanent magnets supported by the magnet carrier in defined positions along the direction of main extension. Each of the permanent magnets is permanently magnetized either longitudinally or diametrically with regard to the direction of main extension. The permanent magnets following to each other in the direction of main extension are arranged in a closure alignment pattern having a magnetic non-repetition length extending over three or more of the permanent magnets. The magnet carrier is bendable in at least one direction orthogonal to the direction of main extension.

A jewelry clasp is disclosed and includes a first part including a first magnet, a first groove and a first catch and a second part including a second magnet, a second groove and a second catch. The first and second magnets generate an attractive force holding the first part to the second part, the first catch is received in the second groove and the second catch is received in the first groove. A relief disposed on at least one of the first part and the second part at an interface between the first part and the second part is provided to aid in releasing the first part from the second part.

An electronic device includes a first housing including a first side surface, a second housing including a second side surface that may face at least a portion of the first side surface, a first magnet group disposed adjacent to the first side surface in the first housing and including a first designated pattern along a lengthwise direction, and a second magnet group disposed adjacent to the second side surface in the second housing and including a second designated pattern along a lengthwise direction, wherein the first designated pattern of the first magnet group and the second designated pattern of the second magnet group are alternately magnetized with an N pole or an S pole, and wherein the first housing and the second housing are coupled together to be rotatable by the first magnet group and the second magnet group.

Cables are magnetically attracted to magnets in straps and other items such as electronic devices. The cables may contain signal lines to convey power and/or data. Magnetic material that is attracted to magnetic fields may be incorporated into the signal lines and/or other structures in the cables. The straps may have flexible magnets and/or other magnets extending along their lengths. The magnets of the straps create magnetic fields that attract the cables. Electronic devices may also have housings that contain magnets to attract the cables. Using magnetic attraction, cables can be removably attached to straps and other items during operation of an electronic device, thereby helping to prevent tangling of the cables.

A closure device includes a first magnet and a housing with a second magnet positioned therein. The first magnet is configured to be position in a first object and the housing is configured to be positioned in a second object. The housing has a top end and at least one adjustment mechanism connected to the housing that moves the second magnet in at least one translational direction or at least one rotational direction relative to the top end of the housing. The movement of the second magnet relative to the top end of the housing adjusts the position or orientation of the second magnet relative to the first magnet to alter a magnetic force between the first magnet and the second magnet when the first magnet is positioned proximate the top end of the housing.

The present disclosure relates to a magnetic assembly structure which utilizes a magnetic attraction or repulsion effect generated by two magnetic components to make two buckle structures automatically engaged to each other. The magnetic assembly structure of the present disclosure has a first main body and a second main body, and via the hardware design of disposing magnetic components and buckle structures respectively on the first main body and the second main body, the first and second main bodies rotate in respect to each other due to the magnetic attraction or repulsion effect, so as to efficiently engage the two buckle structures each other. Thus, it actually eases the installation and uninstallation of the appliance to which the magnetic assembly structure is applied, and the costs of installation and consuming time are reduced.
