Speaker system and cooling device therefor

A cooling device for a speaker system, comprising:

• a first member arranged adjacent to said voice coil and inside a magnetic flux loop generated by said magnetic circuit;
• a second member arranged outside magnetic flux loop generated by said magnetic circuit;
• and
• a third member connecting said first member and said second member to each other, said third member disposed between said magnetic circuit and a yoke,
• wherein said first to third members are formed of a material that is efficient in thermal conductivity
• wherein the cooling device is not a frame.

A speaker apparatus comprising:

• a frame;
• a magnet unit supported by the frame for creating a magnetic circuit, the magnet unit having an upper yoke and a lower yoke;
• a bobbin supported by the frame such that at least part of the bobbin is present in the magnetic circuit, the bobbin having a generally cylindrical shape, the bobbin having a height direction and a radial direction;
• a voice coil arranged around the bobbin, the voice coil having a lower end and an upper end;
• a diaphragm attached to the voice coil and supported by the frame such that the diaphragm and the voice coil are driven by a drive current supplied to the voice coil;
• and
• a cooling device including:
• a first member extending in the height direction of the bobbin such that the first member is adjacent to the lower end of the voice coil;
• a second member extending outwardly from the first member in the radial direction of the bobbin, and
• third member extending from the second member in the height direction of the bobbin such that the third member stands in parallel to the first member.
