    • A dynamic transducer having a voice coil attached to and suspended between two diaphragms that comprise two opposite sides of an enclosure. The voice coil is suspended within the enclosure on a center support that passes through the enclosure and is attached to the diaphragms. Within the enclosure, an annular magnet having a hollow cylindrical ferromagnetic core is disposed between two annular ferromagnetic plates and is attached to one of the plates. A narrow gap is formed within the magnetic structure. The voice coil travels within the gap and is attached to a non-ferromagnetic shaft that extends through the hollow cylindrical ferromagnetic core. The voice coil is fastened to the diaphragm comprising each side of the housing, so that the diaphragms move to produce audible sound. An internal fusing mechanism is directly attached to the voice coil to protect the coil against thermal and electrical overload.
    • 具有附接到并悬挂在包括外壳的两个相对侧的两个隔膜之间的音圈的动态换能器。 音圈悬挂在外壳内的中心支架上,该支架穿过外壳并连接到隔膜上。 在外壳内,具有中空圆柱形铁磁芯的环形磁体设置在两个环形铁磁板之间,并连接到其中一个板。 在磁结构内形成窄间隙。 音圈在间隙内行进并附接到延伸穿过中空圆柱形铁磁芯的非铁磁轴。 音圈被固定到包括壳体的每一侧的隔膜上,使得隔膜移动以产生可听见的声音。 内部定影机构直接连接到音圈,以保护线圈免受热和电过载。
