Sound-transmitting member

摘要

To obtain a sound-transmitting member which has a wide sound transmission band in a high-frequency region. A sheet-like sound-transmitting member (10) having sound transmissivity is obtained by alternately laminating (N + 1) core layers (106A, 106B) and N intermediate layer (104) (N = 1) between two skin layers (102A, 102B). The skin layers (102A, 102B) and the intermediate layer (104) are formed of carbon fiber-reinforced plastics (CFRP) that have higher elastic moduli than the core layers (106A, 106B) that are formed of a rubber.
