摘要： A micro speaker capable of preventing voice coil rubbing, including an outer casing provided with a holding space, a diaphragm installed within the holding space, a magnet provided with an axis, a voice coil encircling the exterior of the magnet and connected to a diaphragm, and an elastic connecting member connected between the voice coil and the magnet. The diaphragm is disposed on the first end, and the magnet is disposed on the second end of the holding space so as to be separated from the diaphragm. The elastic connecting member is used to maintain a clearance between the voice coil and the magnet. After a signal voltage is fed into the voice coil, the diaphragm extends along the axis causing amplitudes of vibration, and the elastic connecting member reduces amplitudes of deflection produced along the axis, thereby preventing rubbing between the voice coil and the magnet from occurring.
