A multiple engine array system and speaker. The multiple engine array system includes at least two engine components, the at least two engine components are mounted at the bottom of the basin rack ofthe loudspeaker, each of the engine components includes a voice coil provided with a voice coil skeleton and a magnetic circuit system for providing a magnetic field to the voice coil, the magnetic circuit system comprises a magnetic bowl, a magnetic and a magnetic conductive plate , the magnetic bowl is arranged at the bottom of the basin rack, the magnetic and the magnetic conductive plate arearranged in the magnetic bowl, a magnetic gap is formed between the magnetic bowl and the magnet and the magnetic conductive plate, the voice coil is suspended in the magnetic gap, and the cross-sectional shapes of the voice coil and the magnetic circuit system are rectangular. The invention has wide application range, can effectively reduce power consumption, improve loudspeaker efficiency, reduce resonant frequency, improve heat dissipation effect, and can reduce various distortions such as non-linear distortion through cooperation and restriction of a plurality of engine components.
