摘要
A method for manufacturing an acoustic body is comprising the following steps: (A) Inserting a plurality of layers into a moulding tool comprising a first moulding half (6) and a second moulding half (7). The second moulding half (7) comprises a plurality of cup-like indentations (8). The plurality of layers at least comprises a first porous skin layer (1) facing the first moulding half (6), a second impermeable skin layer (3,4) facing the second moulding half (7), and a film layer (2) between the two skin layers (1,3,4). (B) Closing the moulding tool and discharging gas from one side in order to press the first skin layer (1) against the first moulding half (6). (C) Shaping and consolidating the first porous skin layer (1). (D) Charging with pressurized air the first space in order to press the second skin layer (3,4) against the second moulding half (7). (E) Shaping and consolidating the second skin layer (3,4). (F) Meanwhile bonding the first and second skin layer (1,3,4) to each other in the area bewteen the cup-like indentations (8), in order to form an acoustic body comprising a plurality of cup-like cavities.
