    • First and second switches are connected at each node between adjacent resistors in a resistor row and at the end of the resistor row. A predetermined number of first switches are grouped together and short-circuited to obtain a plurality of first switch groups, and a predetermined number of second switches are grouped together and short-circuited to obtain a plurality of second switch groups. The first and second switch groups are connected to output terminals via output switches. The first and second switches are ON/OFF controlled such that only one switch in the first and second switch groups is connected to the resistance row.

    • A loudspeaker includes a flat plate diaphragm mounted in a speaker frame and which is driven by a plurality of magnetic drivers each having a magnetic gap, a voice coil bobbin connected to the diaphragm at a respective node portion of the divided vibration mode and a voice coil in the respective magnetic gap and being wound around the voice coil bobbin therein. Rotational vibration of the diaphragm is prevented by a pole member which is connected from the center of the diaphragm to a damper supported behind the speaker frame on a damper supporting frame. The leverage due to the longer length of the pole member makes the damper member more effective in resisting rotational vibration. The damper supporting frame is mechanically connected to the speaker frame and/or magnetic drivers to add stiffness to the structure.
    • 扬声器包括安装在扬声器框架中的平板隔膜,其由分别具有磁隙的多个磁驱动器驱动,在分隔振动模式的相应节点处连接到隔膜的音圈筒管和音圈 在各自的磁隙中并缠绕在其中的音圈筒管上。 通过从隔膜的中心连接到支撑在扬声器框架后面的阻尼器支撑框架上的阻尼器的极构件来防止隔膜的旋转振动。 由于极构件的长度较长的杠杆作用使阻尼构件更有效地抵抗旋转振动。 阻尼器支撑框架机械地连接到扬声器框架和/或磁性驱动器以增加结构的刚度。
