The invention discloses a loudspeaker assembly, an assembly method of the loudspeaker assembly and sound production equipment, the loudspeaker assembly comprises a first pole body, a first magnet anda second magnet, and the first magnet is arranged on the first pole body; the second magnet is arranged on the first pole body and is coaxial with the first magnet, and a gap is formed between the second magnet and the first magnet; a first protrusion is arranged on the side, facing the gap, of the first pole body. According to the loudspeaker assembly, the first protrusions are arranged on the first pole body so that the positioning and limiting effects can be achieved, the assembling efficiency can be improved, the height of the whole loudspeaker assembly can be reduced, and miniaturizationdesign of the loudspeaker assembly is facilitated. In addition, the thickness of the first pole body in the gap is increased due to the fact that the first pole body is provided with the first protrusions towards the gap, more magnetic energy can pass through the gap, hysteresis and magnetic saturation risks can be reduced, and the sound production quality of the loudspeaker assembly can be improved.
