The invention relates to the technical field of loudspeakers, in particular to a loudspeaker which comprises a diaphragm assembly, an inner cover, a base, a shell and a mounting rack, the diaphragm assembly comprises a vibrating diaphragm, an outer cover, U iron, a magnetic conductive plate, magnetic steel and a voice coil, a first groove with a hole is formed in the side wall of the U iron, the hole is used for communicating air between the inside and the outside of the U iron, and when the vibrating diaphragm vibrates, the U iron is prevented from being blocked by the hole. Air between the vibrating diaphragm and the magnetic conductive plate enters the U-shaped iron along the gap between the U-shaped iron and the side wall of the magnetic conductive plate, passes through the hole to the position between the U-shaped iron and the outer cover, then moves to the position between the U-shaped iron and the vibrating diaphragm along the gap between the U-shaped iron and the inner wall of the outer cover and retu
