The present disclosure provides a magnetic housing for mobile device and a manufacturing process of the magnetic housing. The magnetic housing includes a housing body, an outer sleeve, a magnetic coil, and an inner lining. The housing body comprises a bearing part and a surrounding part. The surrounding part is connected to and intersecting with an outer periphery of the bearing part to form an accommodating space. The accommodating space accommodates a mobile device. The bearing part comprises a groove. The outer sleeve is disposed on a surface of the housing body away from the accommodating space. The magnetic coil is disposed in the groove. The inner lining is disposed on a surface of the housing body close to the accommodating space. The overall thickness of the housing for mobile device would not be increased when magnetic coils are disposed.

A protective case for a mobile or handheld device is disclosed. The case includes front and rear cover components that are configured to rotate relative to one another so that the case is capable of being configured by the user into have multi-mode use configurations. The case includes a rotatable magnetic clasp that rotates to magnetically secure the case in desired configuration. The magnetic clasp includes a rotatable magnet component attached to one end region of the case and a fixedly positioned and oriented magnet secured to another opposing end region of the case. The rotation of the magnet allows the user to re-orient the polarity of the magnetic component to facilitate mechanical and magnetic retention of the desired configuration.

A device incorporating both a magnet and a living hinge may be employed to construct cases to protect electronic devices and to function as a closure for cases and lidded containers. Such cases often can be bent three 360 allowing the cases to be either closed protecting devices therein are closed upon themselves allowing the case to function to secure an electronic device to a substrate such as an article of clothing. The devices of the disclosure can also be used to organize and hold loose items together.

Embodiments of the present disclosure relate to a headphone or speaker assembly that contains two or more audio components that are configured to be magnetically coupled together by use of a complementary magnetic pole configuration in the headphone or speaker assembly to provide one or more useful functions. These useful functions may include elements that are able to sense that the two or more audio components are in contact with each other, or are at least proximate to each other, so that their audio playback capability can be suspended while they are in this unused state. A sensor located within one of the components can detect a change in the magnetic field and generate an electronic signal indicating a clasped condition.

Disclosed is a method of magnetising a substrate comprising the steps of: preparing a magnetising coat by dispersing a plurality of particles of at least one magnetisable material in a binder; applying the magnetising coat on a surface of the substrate;

setting the magnetising coat; and magnetising the magnetisable material in the magnetising coat by exposing the magnetising coat to a magnetic field.

A magnetic sealing closure, comprising: a. a first flexible strip, with a plurality of cavities adapted to incorporate a plurality of magnetic elements; b. a second flexible strip, with a plurality of cavities adapted to incorporate a plurality of magnetic elements; wherein said sealing closure comprises membranes connectable to said first strip, and a second membrane connectable to said second strip, such that said plurality of magnetic elements of said second strip are embedded within said plurality of cavities between said second strip and said second membrane; when said first and second strips and are brought together from the side of said first and second membranes, magnetic elements of said first and said second strips magnetically attract each other, such that a sealing is provided.

Provided is an access control electro-permanent magnetic lock for locking and unlocking physical barriers with electromagnetism, but without a continual power source. The lock comprises permanent magnets juxtaposed with electro-permanent magnets. The polarity of the permanent magnets is fixed and aligned. The polarity of the electro-permanent magnets can be switched by introducing a pulse of electric current for a fraction of a second at low voltage to the electro-permanent magnets. A strong magnetic field generating a locking or holding force is produced when the polarity of the electro-permanent magnets aligns with or is in the same direction as the polarity of the permanent magnets. The magnetic field is canceled such that there is no locking or holding force when the polarity of the electro-permanent magnets is opposite to the polarity of the permanent magnets. The lock can further provide fail-secure or fail-safe protections in the event of power loss.

These useful functions may include elements that are able to sense that the two or more audio components are in contact with each other, or are at least proximate to each other, so that their audio playback capability can be suspended while they are in this unused state. A sensor located within one of the components can detect a change in the magnetic field and generate an electronic signal indicating a clasped condition.

An electronic device comprising a first portion and a second portion pivotably connected to each other is disclosed. The electronic device is pivotable between a closed position and an open position. The device comprises a magnetically attractable arrangement within or on the second portion and a magnetic arrangement comprising a magnet having a magnetic field and a magnetic shielding element disposed within or on the first portion. At least one of the magnet or the magnetic shielding element is configured to move translationally with respect to the other between a shielded position and an engaging position when the first portion is pivoted with respect to the second portion. In the shielded position, the magnetic shielding element at least partially reduces a portion of the magnetic field extending outside of the first portion. In the engaging position, the magnet engages the magnetically attractable arrangement.

An electronic device or electronic device assembly may comprise a first portion and a second portion, a first magnet disposed inside the first portion and rotatable about a pivot axis with respect to the first portion, and a second magnet disposed inside the second portion and rotatable about a pivot axis with respect to the second portion. The first and second magnet may be configured to rotate so that the first and second magnets magnetically engage each other when the distance between the first and second magnet is equal to or smaller than a first distance.
