Speaker

摘要

A speaker is disclosed in the present disclosure. The speaker includes a vibration system including a vibrating diaphragm and a flat voice coil for driving the vibrating diaphragm; a magnetic circuit system including two separated permanent magnets with opposite magnetic poles thereof facing each other; a magnetic gap formed between the permanent magnets for partially receiving the flat voice coil; and a housing for accommodating the vibrational system and the magnetic circuit system. Magnetic conductive plates are attached to external surfaces of the permanent magnets. The housing includes a through-hole with a shape matched with the magnetic conductive plates, a wall of the housing has support steps located in the through-hole, and the magnetic conductive plates are placed in the through-hole and are fixed on the support steps.
