Abstract

Disclosed is a loudspeaker, comprising a vibration diaphragm configured to vibrate to generate air-conducted sound waves and a casing configured to form an accommodation cavity. The vibration diaphragm divides the accommodation cavity into a front cavity and a rear cavity, the casing being provided with a sound outlet hole in flow communication with the front cavity, and at least a portion of the air-conducted sound waves being transmitted to the outside of the loudspeaker via the sound outlet hole. The casing is provided with a sound absorption pipe, and the sound absorption pipe is in flow communication with at least one of the front cavity and the rear cavity and configured to absorb sound waves of a target frequency in the air-conducted sound waves, and a length of the sound absorption pipe being in a range of 3/20-2/5 of a wavelength of the sound waves of the target frequency.
