The invention discloses a loudspeaker. The loudspeaker comprises a sound coil and a vibrating diaphragm. The vibrating diaphragm is provided with at least one sound absorption component so as to absorb noise caused by impulse waves. The loudspeaker can absorb microsecond sections and micro impulse waves with the time interval being shorter than that of the microsecond sections, so that the sound quality is effectively improved, digital sounds in the audio field are effectively removed, the sound timbre is made soft, analysis force is increased, and the sound effect is improved.
