Abstract: A thin speaker driver has a supporting frame, a magnet assembly, a voice coil assembly, a spider, a surround, and a diaphragm. The diaphragm is curved in radial section and has multiple coaxially arranged arc portions. A radial section of each arc portion has a curvature radius. The curvature radiuses of the radial sections of the arc portions are different from each other. Two of the arc portions that are disposed adjacent to each other are tangent to each other at which the two adjacent arc portions connect to each other. With the curvature variation of the radial section of the arc portions, different arc portions can be use to create sounds with different pitches. Accordingly, the speaker driver can create sounds with wide frequency responses to achieve full-range operation and thickness of the speaker driver can be greatly reduced, such that the speaker driver can be thinned.

Abstract: A speaker decorative rim mounting structure includes a speaker body holding a speaker driver, a face panel assembly including an outer face panel mounted at the speaker body and an inner face panel mounted within the outer face panel and providing a retaining flange, and a decorative rim holding a metal mesh and having equiangularly spaced bottom hooks directly hooked on the retaining flange of the inner face panel to secure to the decorative rim to the face panel assembly.

Abstract: A speaker mounting structure includes a speaker body holding a speaker driver, a face panel assembly including an outer face panel having a retaining flange extending around the outer perimeter thereof and mounted at the speaker body and an inner face panel mounted within the outer face panel, and a decorative rim holding a metal mesh and having upper and lower hooks alternatively arranged around the inner perimeter thereof and respectively hooked on opposing top and bottom sides of the retaining flange of the inner face panel to secure to the decorative rim to the face panel assembly.
