The present invention discloses a novel kinetic energy earphone speaker, comprising a speaker, a battery, and a PCBA circuit main board. A through-hole is provided in the middle of one side face of the speaker, the battery extends into the through-hole for mounting and arranging, the PCBA circuit main board is sleeve jointed on the extending end of the battery, and a second washer can form one T-type magnetizer with a magnetizer metal casing of the battery. The present invention incorporates part of the volume of the battery into the speaker as a magnetizer, which can reduce the combined use space, make the volume of the product small, and shorten the overall design time.
