An electronic device may include conductive structures with a light-reflecting coating. The coating may have a two or four-layer thin-film interference filter. The two-layer filter may have a CrN layer and an SiCrN layer. The four-layer filter may have two CrN layers and two SiCrN layers. The two-layer filter may be used to coat relatively small conductive components. The four-layer filter may be used to coat a conductive housing sidewall. Both types of interference filter may produce a relatively uniform light blue color despite variations in coating thickness produced on account of the geometry of the underlying conductive structure.

An electronic device is provided. The electronic device includes a housing, a button member which is coupled to the housing and at least a portion of which is exposed to the outside of the housing, a bracket which is disposed inside the housing and on which a circuit board is mounted, a connection member which is disposed in the bracket and is electrically connected to the circuit board, and a conductive structure which is disposed in one portion of the connection member so as to be in contact with the button member, and which is electrically connected to the connection member and the button member, wherein the conductive structure comprises a contact portion in contact with the button member and a fixed portion which extends from the contact portion to the connection member so as to space the contact portion and the connection member apart from each other.

A strap structure and a wearable electronic device comprising same, the strap structure being connected to one side of a housing are provided. The strap structure includes a strap body, a holder body connected to one side of the strap body, a first holder part, which protrudes toward the inside of the housing from the end on one side of the holder body, and is inserted into the housing at an angle of inclination greater than 0 and less than 90 in the inward direction of the housing, with the horizontal direction being defined as 0 and the vertical direction defined as 90 or 90 when the housing is placed with the center thereof facing upward, and a second holder part arranged at the end on the other side of the holder body and inserted into the housing at an angle of inclination less than 0 and greater than 90.

A wearable computing device is provided. The wearable computing device includes a housing and a rechargeable battery disposed within a cavity defined by the housing. The wearable computing device further includes a charging system disposed within the cavity. The charging system includes an alternating current (AC) generator configured to generate alternating current power. The charging system includes a rectifier circuit electrically coupled to a stator of the AC generator. The rectifier circuit is configured to convert AC power to direct current (DC) power. The charging system includes an energy storage device electrically coupled to the rectifier circuit such that the energy storage device is charged with the DC power. The charging system includes a solid state switch configured to selectively couple the energy storage device to the rechargeable battery to transfer charge from the energy storage device to the rechargeable battery.

Types of metal component parts including a casing, a bezel, a buckle, parts for a watch band, etc. are made with the Metal Injection Molding (MIM) process. Each type of metal component part can be derived from an instance of a MIM blank corresponding to that particular type of metal component part formed from its corresponding injection molding tool. The MIM blank formed for the metal component part from the injection molding tool then has a portion of the MIM blank subtracted through a laser subtraction process to form an interim shape and geometry of the instance of the metal component part. The laser subtraction process is applied to the instance of the MIM blank for the metal component part when the instance of the MIM blank has not yet been sintered and hardened to a finished shape and geometry for that metal component part for the watch design.
