[0074] When the first vibration assembly 12 and the second vibration assembly 14 act, after the first voice coil 123 and the second voice coil 143 receive external input electronic signals, the first diaphragm 121 and the second diaphragm 141 simultaneously act outward and simultaneously act inward, when the first diaphragm 121 and the second diaphragm 141 simultaneously act outward and simultaneously act inward, the acting forces on both sides will mutually offset, so that the first vibration assembly 12 and the second vibration assembly 14 can realize the effect of vibration reduction, and avoid that the acting force generated by the action of the first diaphragm 121 and the second diaphragm 141 drives the entire double-sided vibration reduction loudspeaker 1 to vibrate.

In addition, the double-sided vibration reduction loudspeaker 1 of the present application can provide sufficient vibration space for the first voice coil 123 and the second voice coil 143 through the bent connecting portions 157, so as to provide greater vibration stroke.
