STRUCTURE OF THE SPEAKER

摘要

The present invention relates to a structure of a speaker and, more specifically, to a structure of a speaker, capable of improving the centering of a voice coil and reducing heat from the voice coil by changing the structure of the speaker. In the structure of the speaker according to one desirable embodiment of the present invention, a magnetic fluid element is wound around the voice coil to absorb a delicate impact of a bobbin around which the voice coil (16) is wound. A pole piece (22) of the center of a bottom plate (20) is tapered from the upper side to the lower side thereof to prevent the separation of the center of the bobbin. Correspondingly, the bobbin (14) around the pole piece is tapered from the upper side to the lower side thereof. A plurality of air holes (24) are formed on the bottom plate (20) to discharge heat from the speaker to the outside.
