Abstract: The present invention provides a smart wearable device includes a glass frame and a pair of temples. The glass frame includes a connecting portion. Each temple includes a shelf, a cover plate, and a rotating shaft assembly matched with the connecting portion. The shelf includes an upper wall and a lower wall. The rotating shaft assembly includes a first rotating shaft bracket, a second rotating shaft bracket, a screw, and a positioning bead assembly. The positioning bead assembly is movably connected between the first and the second rotating shaft bracket to realize a folded and an unfolded state of the smart wearable device. The smart wearable device of the present invention uses a rotating shaft assembly to realize the folded and unfolded states. The smart wearable device has a simple structure, requirements of the processing accuracy and assembly accuracy of components are low, and the development cost is low.

Abstract: Disclosed are a directional bilateral sound intake-based MIC assembly and an electronic device. The electronic device includes the directional bilateral sound intake-based MIC assembly. The MIC assembly includes a front shell with paired sound inlet holes and a microphone arranged on an inner side of the front shell. The microphone has two receiving holes. The MIC assembly further includes a fixture assembled within the inner side of the front shell. An assembling chamber and two sound inlet channels in communication with the assembling chamber are defined in the fixture. The microphone is mounted within the assembling chamber. The two receiving holes of the microphone are in communication with the two sound inlet channels respectively. The two sound inlet channels are in communication with a same pair of two sound inlet holes respectively.

Abstract: A method for adjusting a strap of a VR device is provided and includes a method for tightening the strap. The method for tightening the strap includes obtaining, by tightening trigger, a tightening trigger signal; controlling, by PCB, a driver to drive a transmission component according to the tightening trigger signal to drive first and second straps to be tightened synchronously; obtaining, by pressure sensor, a pressure value of a preset part; and when the pressure value reaches a first preset value, controlling, by PCB, the driver to stop driving the transmission component according to a first pressure sensor signal, such that first and second straps are synchronously tightened to an appropriate position. The method automatically adjusts the tightness of straps, reducing user's operation processes and making it convenient and faster for the user to wear the VR device. The method can ensure moderate tightness for all user head shapes.

Abstract: A multifunctional protective case for a tablet computer includes a front plate (110) with a sandwich structure (111), a holding plate configured to hold a back of the tablet computer and a supporting plate (130) connecting the front plate (110) and the holding plate (120) via a bendable portion (140) to support the tablet computer. A printed circuit board (112) with wireless router functionality is installed in the sandwich structure (111) in the front plate (110), therefore enabling the protective case with wireless router functionality. The printed circuit board (112) can be connected with an external wireless network card, and the tablet computer can get access to a cellular network once placed in the multifunctional protective case and connected to the printed circuit board.

Abstract: The present disclosure generally relates to a protective case for a tablet computer, includes: a front plate (110) having a first surface (111) configured to protect a display surface of the tablet computer, wherein a magnetic element (112) is installed on the first surface (111); a holding plate (120) being configured to hold a back of the tablet computer; a supporting plate (130) connecting the front plate (110) and the holding plate (120) to prop up the tablet computer; wherein the magnetic element (112) can be installed at different positions on the first surface (111), in order to enable the tablet computer to stand up at different angles. The magnetic element (112) installed on the first surface (111) of the front plate (110) is attracted with a bottom end of the tablet computer, thus a steady triangle frame is formed between the tablet computer and the folded protective case, further enabling the tablet computer to stand up at different angles.
