An electronic device includes a casing including an annular light-emitting area, a plurality of directly-lit light sources, a light guide plate disposed between the directly-lit light sources and the annular light-emitting area, and a light-shielding rib structure located between the directly-lit light sources, and separating any two adjacent ones of the directly-lit light sources. The light guide plate includes opposite first and second surfaces and a plurality of recessed structures recessed in the second surface. The recessed structure has a corresponding semi-conical surface, and the semi-conical surface faces a zone of the light guide plate. The directly-lit light sources face the first surface and respectively correspond to the semi-conical surfaces. Light emitted by the directly-lit light sources enters the light guide plate and is reflected by the semi-conical surfaces, passes through the zones of the light guide plate, and is transmitted to the annular light-emitting area to emit outwardly.

A microphone having a light-emitting structure includes a housing, a main body, and multiple light-emitting structures. The main body is disposed in the housing. The light-emitting structures are disposed between the housing and the main body and fixed on the main body. Each of the light-emitting structures includes a light-emitting module and a light guide structure. The light-emitting module includes a circuit board and multiple light-emitting elements, and the light-emitting elements are disposed on the circuit board. The light guide structure includes a groove and a light guide part. The groove covers the light-emitting module. The light guide part is mountain-shaped and extends from the groove toward the housing.

A speed reducer used in a server is disclosed to include a first planetary gear set, a planet gear carrier, an internal gear surrounding the first planetary gear set, and an output gear. The first planet gear includes a first sun gear mounted on the motor output shaft, at least one first planet gear pivotally coupled at the first planet gear carrier and meshed with the first sun gear and the internal gear for driving the first planet gear carrier and the output gear to rotate. Thus, the first planetary gear set reduces the revolving speed of the rotary driving force outputted by the motor output shaft, and effectively transfer the rotary driving force to the output gear, achieving the advantages of low backlash and long service life, reducing power transfer loss, increasing server output torque, and providing high speed ratio, high design flexibility and high assembly yields.
