Abstract: A headband adjustment structure includes a rotary adjusting assembly, a wearing unit having an adjustable accommodation space, a cable management module located between the wearing unit and the rotary adjusting assembly for carrying a cable, an adjustment gear set linkably coupled to the cable management module, and a driving rotation shaft set passing through the wearing unit and the cable management module, and linkably coupled to the wearing unit and the adjustment gear set, and coaxially connected to the rotary adjusting assembly. When the rotary adjusting assembly rotates the driving rotation shaft set, the driving rotation shaft set synchronously moves the wearing unit to adjust the adjustable accommodation space, and moves the cable management module through the adjustment gear set. The amount of the movement of the cable management module is different from that of the wearing unit.

One end of the linkage device is slidably received within the guide grooves, the other end thereof is pivotally connected to the wearable device.

Abstract: A fastener includes a sleeve and a rod received in the sleeve. The sleeve includes a top end including at least one outer flange extending radially outward therefrom and at least one inner flange extending radially inward therefrom and a lower end including at least one spring tab. At least one spring tab comprises an outer flange at its end that extends radially outward. the sleeve is inserted into the receiving holes of the top article and the bottom article until the outer flange of the top end rests on the top plate, the rod is then pressed to move to drive at least one spring tab to deflect outwardly until the outer flange of at least one spring tab is held in contact with the bottom plate.

Abstract: A method for affixing adhesive films to a main board is provided. The main board includes a main body and a shield. The shield includes a first shield and a second shield. The second shield defines openings. When the second shield is attached to the main body, components of the main body are confined within the openings, respectively. The method includes: first absorbing a single adhesive film to an electrostatic absorbing film. Then, stamping the electrostatic absorbing film and the single adhesive film to form adhesive films that have substantially the same shape and arrangement as the openings. Next, aligning the electrostatic absorbing film with the first shield and affixing the adhesive films to the first shield. Then, removing the electrostatic absorbing film from the first shield. And, assembling the first shield to the second shield.

Abstract: An electronic device and a slide switch are disclosed. The slide switch includes a main body, a slider, a rotary plate rotatably connected to the main body, and a rotary arm. The main body includes a fixing space, a channel, and a first contact member protruding from a bottom of the fixing space. The slider is movable between a first position and a second position within the channel. The rotary plate includes a lateral surface and a second contact member protruding from the lateral surface. Two ends of the rotary arm are respectively connected to the slider and the lateral surface. When the slider is located in the first position, the first contact member spaces from the second contact member; when the slider is moved to the second position, the rotary arm rotates the rotary plate causing the first contact member to contact the second contact member.

Abstract: An electronic device includes a housing and a button. The housing defines a through hole. The sidewall of the through hole defines a pair of positioning holes. The button includes a frame, a sliding bar assembly, an elastic conductive member, and a pressing member. The sliding bar assembly is received in the frame with two external ends respectively received in the positioning holes to cause the frame to be received in the through hole. The elastic conductive member is fixed in the housing. The pressing member hooks the frame and extends through the frame to resist the sliding bar assembly. When the pressing member is depressed, the pressing member resists the sliding bar assembly to cause the external ends to move out of the positioning holes. Further depress on the pressing member causes the frame to press the elastic conductive member to actuate the button.
