Abstract: A speaker capable of active cooling includes a basin frame, and a vibration system and a magnetic circuit system accommodated in the basin frame. The vibration system includes a diaphragm and a voice coil fixed on the diaphragm through a top end of a winding portion thereof. The magnetic circuit system includes a T-iron, a magnet and a washer, wherein the washer and the magnet are located above the T-iron, a magnetic gap is formed between the washer and the magnet and the T-iron, and the voice coil moves up and down in the magnetic gap. The speaker further comprises an active cooling module fixed to a back of the T-iron, and the active cooling module cools the magnetic circuit system by means of heat conduction.
