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.
摘要翻译：本发明涉及扬声器的结构，更具体地说，涉及扬声器的结构，其能够通过改变扬声器的结构来改善音圈的定心并减少来自音圈的热量。在根据本发明的一个期望的实施例的扬声器的结构中，磁性流体元件缠绕在音圈周围以吸收缠绕有线圈（16）的线轴的微妙冲击。底板（20）的中心的极片（22）从其上侧向下侧渐缩，以防止线轴的中心分离。相应地，极片周围的线轴（14）从上侧向下侧逐渐变细。在底板（20）上形成多个气孔（24），以将扬声器的热量排出到外部。
