3. The speaker device according to claim 2, wherein the first and second coils are configured to drive the vibrating film based on the same voice signal in the same phase.
4. The speaker device according to claim 3, wherein the first and second coils are fixed to both surfaces of the vibrating film, in the same shape and at the same position.
5. The speaker device according to claim 3, wherein the first and second magnets are formed so that the sides facing the vibrating film are mutually magnetized in heteropolarity, and the first yoke has an annular outer wall extending to the vicinity of a tip of the vibrating film of the first magnet with the first coil interposed between them, and the second yoke has an annular inner wall extending to the vicinity of a tip of the vibrating film of the second magnet with the second coil interposed between them.
6. The speaker device according to claim 3, wherein lead wires for applying the voice signal to the first and second coils, are formed so as to be led out from the first and second coils to an outer edge diagonally on one surface side and the other surface side of the vibrating film.
7. A speaker device comprising:
a cylindrical body frame;
a vibrating film supported in the body frame so as to close the body frame;
a first driving unit disposed in the body frame on one surface side of the vibrating film and configured to drive the vibrating film based on an applied voice signal;
a second driving unit disposed in the body frame on the other surface side of the vibrating film and configured to drive the vibrating film based on the applied voice signal, in the same direction as a vibrating direction of the vibrating film vibrated by the first driving unit;
wherein the first driving unit comprises:
a magnetic first yoke disposed in the body frame so as to face a central area of the vibrating film on one surface side of the vibrating film, and formed into a cup-shape;
a first magnet disposed in the first yoke so as to face the central area of the vibrating film; and
a cylindrical first coil fixed to the vibrating film on one surface side of the vibrating film, and inserted into an outer periphery of the first magnet, with a slight space provided between them,
and the second driving unit comprises:
a magnetic second yoke disposed in the body frame so as to face an annular outer peripheral area surrounding the central area of the vibrating film on the other surface side of the vibrating film, and formed into a ring-shape;
a ring-shaped second magnet disposed on a vibrating film side of the second yoke so as to face the outer peripheral area; and
a cylindrical second coil fixed to the vibrating film on the other surface side of the vibrating film, and inserted into an inner periphery of the second magnet, with a slight space provided between them.
