A loudspeaker with low-frequency oscillation, comprising: a housing ( 21 ) with a ring portion ( 211 ) extending inwardly from the bottom thereof; and a reed element ( 22 ) having a top end attached to an oscillatable sound assembly, the reed element ( 22 ) further having an external ring ( 221 ) and two vibration arms ( 222 ) symmetrically extending from the internal side of the external ring ( 221 ) to the internal side of the loudspeaker in a bent manner, each of the vibration arms ( 222 ) having a free end ( 223 ) extending to the center of the reed element ( 22 ), the oscillatable sound assembly including either a magnetic ring ( 25 ) or a coil ( 28 ) disposed within the housing ( 21 ), the ring portion ( 211 ) being attached to either another coil corresponding to the magnetic ring ( 25 ) or another magnetic ring corresponding to the coil ( 28 ), whereby, when the coil ( 28 ) is fed with electric current, a magnetic force is created to impart an up and down vibration to the oscillatable sound assembly, thereby enhancing the effect of the low-frequency sound field as well as the resonance effect.
