The object of the present invention is to provide an acoustic vibration system with a speaker for air mattresses. This vibration system includes an air mattress (20) consisting of a sealed body and inflated with air. One or more speakers (30) are mounted on the sealed body of the mattress, and are connected to an external audio system (31). The speakers (30) thus convert electrical energy outputted from the audio system (31) into sound energy, and radiate the sound energy into air inside the mattress (20), thus acoustically vibrating the mattress. In the vibration system, the sealed body of the mattress is made of a three-dimensional woven fabric (1) such that the sealed body has a desired durability and effectively resists expansion pressure. A coated layer is formed on the internal surface of the woven fabric (1) so as to prevent a flow of air through the fabric.
