A buckle-type closing device (30), placed between two parts to be connected to one another, comprises a first component (31) and a second component (32) that are associable with one another in a releasable manner in which said first component (31) of said closing device (30) comprises a chamber (33) in which a magnet (34) is housed and a support element (35), and in which said second component (32) comprises a ferromagnetic locking element (40) that is adapted to interact, in operation, with said magnet (34), said locking element (40) being movable between a first released position and a second locking position in which it (40) is attracted by said magnet (34) against said support element (35), said locking element (40) consisting of a lever that is rotatable with respect to a pin (43), said lever having a folded end (46) forming a coupling element associable with said support element (35), said second component (32) comprising a mechanical element adapted to act on said locking element (40) to overcome the force of magnetic attraction of the magnet (34) and return the locking element (40) to the released position of said first component (31) with respect to said second component (32) of said closing device (30). Said mechanical element comprises a pair of release components (42) that are elastically opposite one another specularly with respect to the longitudinal centreline of said closing device (30), each release component comprising a respective inclined plane (44) adapted to release said locking element (40) wedging itself between said rotatable lever and a fixed part, and removing said rotatable lever with respect to said magnet (34) and thus releasing said locking element (40) from said support element (35).

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 bracelet having a first separation body (100) connected with a first button body (102) having an accommodation part (104) and a limiting part (105) connected and a second separation body (101) connected with a second button body (103) of which abutment surface having an accommodation slot (109); the accommodation part (104) is located within the accommodation slot (109), slot walls of the accommodation slot provided with bayonets (106), the limiting part (105) engages the bayonet (106), and the width of the bayonet (106) is smaller than of the accommodation part (104); a magnetic assembly (107,108) is provided between the bottom of the accommodation slot (109) and the accommodation part (104) for connecting the first button body (102) to the second button body (103); the direction of the suction force generated by the magnetic assembly is parallel to the direction that the accommodation part (104) enters the accommodation slot (109).

A belt connection structure of a wearable product is provided. A first transmission rack is provided on a side wall of a first elongate hole. A second transmission rack is provided on a side wall of a second elongate hole facing the first transmission rack. A gear is engaged with the first and second transmission racks respectively. A connecting member coaxial with the gear is provided on a side surface of the gear. A sleeve communicating with a slide way is provided on the outer side wall of an outer cover. The inner side wall of the sleeve is provided with teeth extending in the axial direction. At least two annular grooves are formed on the outer side wall of the sleeve. A belt button is mounted on the sleeve, and comprises a pressing portion and a connecting column. The pressing portion and the connecting column are slidable in the axial direction but are not rotatable relative to each other. Position limiting teeth are provided on the outer side surface of the connecting column. The circumferential surface of the connecting column is further provided with a snap-fit flange spaced from the connecting column. The snap-fit flange is engaged with an annular groove.
