Abstract
A speaker system and a cooling device therefor is provided which is capable of effectively dissipating heat generated by a voice coil. The cooling device is formed as a unitary member having a first member having a hollow cylindrical shape which is integrally formed with a second member having a hollow cylindrical shape which is concentric thereto and has a larger diameter than the first member, and a plurality of third members each in the form of a plate and radially arranged between the first member and the second member for connecting the members. The first member is arranged adjacent to the voice coil and at the same time inside a magnetic flux loop generated by a magnetic circuit, and the second member is arranged outside the magnetic flux loop, so that heat generated by the voice coil can be efficiently dissipated from the second member.
