SOUND-TRANSMITTING MEMBER

To obtain a sound-transmitting member having a wide sound-transmitting band in a high frequency region. A planar sound-transmitting member (10) having sound-transmitting properties includes two skin layers (102A) and (102B), N + 1 core layers (106A) and (106B), and N intermediate layers (104) (N = 1...

Summary:To obtain a sound-transmitting member having a wide sound-transmitting band in a high frequency region. A planar sound-transmitting member (10) having sound-transmitting properties includes two skin layers (102A) and (102B), N + 1 core layers (106A) and (106B), and N intermediate layers (104) (N = 1), in which the core layer and the intermediate layer being alternately stacked between the skin layers. The skin layers (102A) and (102B) and the intermediate layer (104) are formed of carbon fiber reinforced plastics (CFRP), which is a material having a higher elastic modulus than the core layers (106A) and (106B) formed of rubber.
