Abstract: The present invention discloses a micro speaker unit with a waterproof effect, including an outer casing which is provided with an accommodation space and a sound hole, and a micro speaker which is installed in the accommodation space. The micro speaker is assembled from a vibrating diaphragm assembly and a magnetic assembly which is inter-assembled with the vibrating diaphragm assembly. The vibrating diaphragm assembly separates the accommodation space into a front chamber and a rear chamber which are not interconnected; whereas, the front chamber is connected with the sound hole. Therefore, water vapor outside the micro speaker unit can be prevented from entering into the rear chamber and the micro speaker by the vibrating diaphragm assembly, thereby improving the waterproof effect of the entire micro speaker unit.

Abstract: The present invention discloses a Fresnel lens with a light receiving effect, including a converging surface and an incidence surface opposite to the converging surface. The incidence surface is provided with an optically effective refractive region and an optically reflective region annularly surrounding the optically effective refractive region.
