  • Patent number: 6871724
    Abstract: A frame of an electroacoustic transducer is made from a mixture of a thermoplastic resin and long fibers dispersed in the resin. The long fibers serve as reinforcing fibers. The long fibers have an average length sufficient to achieve a spring back effect. The spring back effect creases a foam structure. The electroacoustic transducer frame includes single-layer portions and three-layer portions. The single-layer portion is made of a non-foam layer. The three-layer portion is made of a pair of non-foam layers and a foam layer sandwiched by the non-foam layers. The electroacoustic transducer frame is lightweight, and has high internal loss, high rigidity and improved environmental resistance.
