Abstract
The present disclosure discloses a speaker comprising a housing and a sound producing unit fixed to the housing; the sound producing unit comprises: a frame, a vibration system, a magnetic circuit system and a spring damping element; the spring damping element supports the magnetic circuit system in vibration in the holding space; a counterweight block housed in the rear cavity and fixed to a side of magnetic bowl away from the magnetic circuit system. The speaker of the present invention constitutes another vibration system by means of a magnet or a magnetic bowl and a spring damping element, which vibrates opposite to the vibration system consisting of a diaphragm-dome-voice coil, resulting in a reduction of the force on the cone frame; the addition of a counterweight block reduces the effect of air in the rear cavity on the magnet; the magnetic through-holes and leakage holes optimize vibration damping.
