摘要： A miniature speaker includes a frame; a vibration system including a diaphragm and a voice coil driving the diaphragm. The diaphragm includes a first fixation part located on a middle position of the diaphragm, a second fixation part located on an edge of the diaphragm and connected fixedly on the frame, and a vibration part connected between the first fixation part and the second fixation part. A magnetic circuit system includes a lower plate and a magnet part on the lower plate. A cover plate includes a bottom wall, and a side wall connected with the second fixation part. A gasket is located between and abuts against the bottom wall and the first fixation part. The gasket, the first fixation part and the magnet part are sandwiched firmly between the bottom wall and the lower plate.
