Abstract: A thin double-sided vibrating speaker includes a magnet member, a first vibration assembly and a second vibration assembly; the magnet member includes a main magnetic plate, a first magnetic path unit, a second magnetic path unit and side magnetic path units, the first magnetic path unit is disposed on one surface of the main magnetic plate, the second magnetic path unit is disposed on another surface of the main magnetic plate, the side magnetic path units are disposed on the main magnetic plate and correspond to two sides of the first magnetic path unit, the first vibration assembly is disposed on one surface of the magnet member, and the second vibration assembly is disposed on another surface of the magnet member. Accordingly, in addition to achieving the requirement of thinning, the thin double-sided vibrating speaker of the present disclosure also has the effect of vibration reduction and two-way sounding.
