摘要： An electro-acoustic transducer of the moving coil type, which includes a driven unit including a drive coil, and a magnet unit including a magnet and two pole-piece so located as to define an annular air gap in which the coil is located. The driven unit further includes a substantially circular central portion whose outer periphery is secured to the coil, and an outer portion whose inner periphery is secured to the coil and whose outer periphery is secured to a member of said transducer, which contains said magnet unit at a flat face of the member. The transducer member is substantially cylindrical. A flat cup-like member of larger diameter than the member is secured to the flat face. The driven unit also includes a cone whose inner periphery is secured to the coil and whose outer periphery is secured to the outer rim of the cup-like member.
