The present application discloses a miniature speaker. The miniature speaker includes a vibration system including a diaphragm, a voice coil for driving the diaphragm, and a suspension connected to the voice coil; a magnetic circuit system interacting with the voice coil for driving the diaphragm to radiate sound waves; and a frame for accommodating the vibration system and the magnetic circuit system. The suspension includes an outer edge connecting to the frame, an inner edge engaging with the voice coil, and a plurality of spring arms connecting the outer edge to the inner edge. The suspension includes a first isolative layer, a second isolative layer, and a conductive layer. The first isolative layer forms a mounting surface out of which at least part of the conductive layer exposes for connecting to the voice coil.
