A wearable electronic device, for example a smart watch, has an optical sensor module disposed near a side of the device meant to face the wearer. The device also includes a wireless charging module. The optical sensor and wireless charging modules are at least partially integrated together via a flexible printed circuit board (FPCB) which is connected to both modules. The wireless charging module surrounds the FPCB of the optical sensor module, thus allowing a reduction in thickness of the wearable device and further allowing simplification in a process of assembly of the device.

A magnetic levitation device for levitating a marker or suspending the marker away from the device having a housing having an outer portion and a lower portion. The device has an electromagnetic configuration positioned on disc and the disc can move or rotate the marker at a constant or variable speed. The rotating disc is configured with the electromagnetic configuration and a gear assembly.

A support assembly includes a left support frame, a right support frame, and a bracket. The left support frame and the right support frame are both slidably connected to the bracket. The bracket defines receiving grooves. The left support frame includes a first tooth portion. The right support frame includes a second tooth portion. When the support assembly is in a folded state, teeth of the first tooth portion and teeth of the second tooth portion are received in the receiving grooves to support the screen assembly in a retracted state; when the support assembly is in an unfolded state, the teeth of the first tooth portion and the teeth of the second tooth portion extend out of the receiving grooves to support the screen assembly in an extension state. A dial plate and a smart bracelet are further provided.

Disclosed is a novel timer module. The novel timer module includes a replaceable movement, a master control circuit board, an upper housing, and a lower housing. A circuit board is disposed inside the replaceable movement. Five first inserting pins are welded on the circuit board. The first inserting pins are exposed from the outside of a housing of the replaceable movement. The master control circuit board is located in the upper housing and the lower housing, and is fixed on an upper surface of the lower housing. A relay is disposed inside the master control circuit board. Contacts of the relay respectively extend and are fixed on a surface of the master control circuit board by using leads. Therefore, a problem that a conventional timer movement is fixedly welded on a circuit of a timer module can be resolved.

A housing assembly, a wearable device and an assembling method are provided. The housing assembly includes: a middle frame with an opening; a screen assembly that is located on the middle frame and covers the opening; an edge of the screen assembly provided with a stepped structure; an annular member that is disposed at the stepped structure of the screen assembly; a center of the annular member being aligned with a center of the opening; a connector that connects the annular member and the middle frame. Furthermore, at least one of the annular member or the middle frame is made of metal.

A portable electronic device may have an electronic device strap. The strap may include inner and outer fabric layers and optional intermediate fabric layers. The inner fabric layer may have strands of material that are characterized by a larger denier per filament value than the outer fabric layer to help draw moisture away from the body of a user. The fabric layers may have stretchable warp fibers that allow the strap to be stretched. Weft fibers at the bottom of grooves that span the width of the strap may be provided with different colors than other weft strands. When the strap is stretched, the visibility of the weft fibers at the bottoms of the grooves may increase. A hook-and-loop fastener may be used to close the strap. Loops for the fastener may be formed from warp strands and may have multiple sizes.
