A suspension supports a magnetic circuit assembly vibratably in the cylindrical side wall. The suspension has a ring-shaped outer section integrally formed along the peripheral edge of the second end opening of the cylindrical side wall, an inner section provided at the radial center of the cylindrical side wall, and a connecting section that interconnects the inner and outer sections. The inner, outer and connecting sections are integrally molded with the casing.
