Abstract: A light filtering assembly is installed in a lens module, including a fixed mount having a hollow part, a light filter at the hollow part, a shutter annularly disposed on the light filter, and a binding element. The hollow part is annularly formed by a support part extending from the fixed mount toward the hollow part. A first binding space is formed between the support part and the fixed mount, extending the outer periphery of the light filter and the shutter into the first binding space. An adhesive material is injected into the first binding space, and is then cooled down to form the binding element in the first binding space, so as to stop the light filter and the shutter at the hollow part as well as fix the light filter and the shutter on the fixed mount.

Abstract: A diaphragm for a micro loudspeaker includes an outer casing that is provided with a through-hole, a membrane that is disposed in the through-hole, and a suspension that connects the membrane and the outer casing. The outer casing is provided with an inner wall that wraps into the through-hole. The suspension includes an effective operation zone that is extended from the inner wall into the through-hole, and a fixed area that is extended from the inner wall to outside the through-hole. The fixed area of the suspension is provided with a cut-off area, which keeps the effective operation zone at a good intactness, and enables the membrane to vibrate up and down more uniformly, thereby improving the sound quality of micro loudspeaker.
