Summary: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.
