| titleOfInvention | Filling structure of sound absorption material in loudspeaker cavity and closed loudspeaker system |
| abstract | The invention relates to a filling structure of a sound absorption material in a loudspeaker cavity and a closed loudspeaker system. The closed box part is suitable for a closed loudspeaker system or a loudspeaker system and comprises a loudspeaker single body, a box body of the closed loudspeaker system and a sound absorption material component used for wrapping the sound absorption material; the sound absorption material assembly is arranged in the box body and comprises a sound transmission front end face and a sound transmission rear end face, and the front end face and the sound transmission rear end face are perpendicular to the sound transmission direction; the peripheral frame of the sound absorption material assembly is a hard frame, and the outer surface of the hard frame is used as an installation surface and is tightly matched and fixed with the inner wall of the box body or the installation part on the inner wall of the box body; the thickness of the sound absorption material component is smaller than the length of the box body in the sound transmission direction, so that a space which is not filled with the sound absorption material is reserved inside the box body in the sound transmission direction. The invention can reduce the filling cost of the sound absorption material and simultaneously ensure that the performance of the loudspeaker system is better. |
