| titleOfInvention | Preparation method of sound absorption piece |
| abstract | The invention discloses a preparation method of a sound-absorbing piece. The preparation method comprises the following steps: providing a three-dimensional network framework matched with the shape of a rear sound cavity of the sound generating device; attaching a binder to a surface of the three-dimensional network skeleton; bonding a non-foamed sound absorbing material to the surface of the three-dimensional network skeleton by the adhesive; drying the three-dimensional network framework bonded with the non-foaming sound-absorbing material; and roasting the dried three-dimensional network framework to form a blocky sound-absorbing piece. |
