The present application provides a loudspeaker device, comprising: a cover body which forms an accommodation space and a sound producing unit accommodated in the accommodation space. A sound-absorbing cavity for containing sound-absorbing powder is provided in the cover body. The cover body is provided with a first through hole allowing the sound-absorbing cavity to be communicated with the outside. The loudspeaker device further comprises a packaging component mounted on the outer surface of the cover body and covering the first through hole. The packaging component comprises a sealing element and a gas-permeable spacer which are stacked. The sealing element is provided with a first opening. The sound-absorbing cavity is communicated with the outside by means of the first through hole and the first opening. By improving the first through hole communicated with the accommodation cavity on the surface of the loudspeaker device, the through hole can be used for powder filling and as a leakage channel, the through hole is provided with a packaging component, and the hole size on the packaging component is adjusted and the specification of the mesh cloth is adjusted, thereby achieving sound-absorbing powder sealing and leakage damping effects, and simplifying the assembly process.
