1. A multi-input-driving loudspeaker comprising:
a frame;
a diaphragm arranged on the frame;
a plurality of input driving mechanisms, each input driving mechanism comprising a voice coil and a magnetic circuit assembly for driving the voice coil to vibrate;
a plurality of magnetic circuit mounting holes arranged on the frame, wherein at most one magnetic circuit assembly is arranged at each of the plurality of magnetic circuit mounting holes; and
a plurality of voice coil mounting holes are arranged on the diaphragm, wherein at most one voice coil is provided at each of the plurality of voice coil mounting holes,
wherein each magnetic circuit assembly comprises a U-yoke having an inner cavity, a magnetic steel and a magnetic pole core arranged within the U-yoke, a magnetic gap is formed between the magnetic steel and the magnetic pole core and an inner wall of the U-yoke, wherein the voice coil is inserted in the magnetic gap and capable of moving in an up-and-down direction, and an upper edge of the U-yoke is fixedly connected to a respective magnetic circuit mounting hole of the plurality of magnetic circuit mounting holes of the frame, and
wherein the upper edge of the U-yoke is fixedly connected to an inner hole-wall of the respective magnetic circuit mounting hole of the plurality of magnetic circuit mounting holes or a lower surface of the frame adjacent to the respective magnetic circuit mounting hole of the plurality of magnetic circuit mounting holes.
