Low-profile latching mechanisms and related mechanical interfaces for allowing straps and other fastening accessories for limb-wearable devices are provided. The mechanisms in question allow for a very strong, yet easily releasable, connection to be made between a strap accessory and a device housing, with very little of the mechanism being visible.

A wristband can comfortably secure an electronic device, such as a wristwatch or fitness/health tracking device, to a wrist of a user. The wristband can include a number of magnets that allow the wristband to be magnetically coupled to itself when folded over or when separate band portions are overlapping. The magnets can include a polymer mixed with a magnetic material to provide magnetic properties and flexibility. The magnets can be joined together by a continuous support structure that extends through opposing pairs of the magnets. The support structure can provide substantial and ability as well as tensile strength. The magnets and the support structure can be surrounded by a flexible cover to protect the components within.

Closure devices for simply and securely fastening items of jewelry, such as hoop earrings and bracelets, to a body of a wearer are described. The closure device includes a post element and a latch. The post element is movably connected to a hinge, wherein the hinge is attached to a first end of an item of jewelry. The latch includes a first and second side wires, which are joined at a closed end to form a loop. The latch is attached to a second end of the item of jewelry. A width of the loop is less than a width of the post element. The closure device secures the item of jewelry to a person by removably but securely connecting between the first and second ends of the item of jewelry by fastening the post element between the first side wire and second side wire of the loop.

Attachment systems for attaching a wearable electronic device to a user including a sizing band and a retaining band are disclosed. The sizing band includes at least one sizing eyelet and a band-insertable end. The retaining band includes at least a post for insertion into the sizing eyelet of the sizing band and a concealment aperture configured to receive the band-insertable end of the sizing band. On a bottom surface of the retaining band can be a recessed guide bed configured to guide the band-insertable end along the bottom surface of the retaining band. A wearable electronic device can couple to both the sizing band and the retaining band by accepting an end portion of each band into receiving channels extending into opposite sidewalls of the housing.

Belts (1, 20, 30), straps or similar items are described, equipped with means adapted to fasten their free end, such means being applicati to the free end of the belts, straps or similar items. The items can be belts for clothing, straps for shoes and leather goods in general, for watches, for costume jewelry or jewelry bracelets, and can be applied in all cases in which it is necessary to fasten the excess part; the means adapted to fasten the free end comprise a retention device (3, 32), applied to a hole (1c, 20c, 30c) of the belt (1, 20, 30), adapted to connect the free end (1a, 20a, 30a) of the belt (1, 20, 30) to a part (1b, 20b, 30b) of the belt (1, 20, 30), which adheres to the body of the person who wears it, the retention device (3, 32) being equipped with first means adapted to hook the adhering part (1b, 20b, 30b) of the belt (1, 20, 30), and second means adapted to hook the free end (1a, 20a, 30a) of the belt (1, 20, 30).

Disclosed is an AI voice interaction device, including a main body and an earphone detachably connected with the main body. User's voice is picked up by a voice pick-up, digital voice signals are obtained through analog-to-digital conversion, and are further transmitted to a first communication module through an earphone communication module. A body processor implements communication connection with a cloud server, and transmits to the cloud server for voice recognition and semantic analysis. Afterwards, the cloud server implements the functions such as making phone calls, sending short messages through the cellular transceiver, or calls corresponding network data, and transmits the network data back to the wristband-type AI voice interaction device to perform corresponding voice broadcasting according to the network data. Further, a TWS earphone and a wristband-type AI voice interaction system are disclosed.

A bandage may include a first strap and a second strap. The first strap may include a first strap body, a first connection portion and a first mating portion. The first strap body may define a connection hole between the first connection portion and the first mating portion. The second strap may include a second strap body, a second connection portion, a second mating portion and a buckle. The second mating portion may be arranged between the second connection portion and the buckle. The buckle is configured to be inserted into the connection hole to connect the first strap body and the second strap body. The second mating portion may be configured to be attracted to and coupled with the first mating portion.

A versatile smart device holder that secures the device to a user while offering enhanced protection during physical activity as compared to conventional device bands and holders. The device holder is suitable to wear in a number of locations, such as across the bicep, the forearm, leg, ankle, or the wrist. The device holder comprises a band made of flexible material and a frame permanently or removably embedded within or attached to the band that is capable of securely holding the electronic device in place.

A watch includes a case having a dial, a first strap attached to a first end of the case, the first strap having a plurality of adjustment holes, a second strap attached to a second end of the case, the second strap having a buckle for mating with at least one of the adjustment holes, an adjustable loop disposed over the second strap and having a base portion and a top plate coupled to the base portion and defining a gap therebetween, the adjustable loop being transitionable between a first condition where the base portion and the top plate are relatively far from one another and the gap has a first length, and a second condition where the base portion and the top plate are relatively close to one another and the gap has a second length, the second length being less than the first length.
