    • A moving coil drive unit for exciting a resonant member into a vibrational state is disclosed. The moving coil drive unit comprises a magnet assembly and a coil assembly comprising a voice coil arranged concentrically with the magnet assembly and configured such that the voice coil is moveable axially relative to the magnet assembly in use. The magnet assembly comprises a permanent magnet and one or more pole pieces. The magnet assembly is configured to provide an annular magnetic gap, the voice coil being suspended therein. The pole piece is configured to have a laminated structure comprising at least two spaced layers. The pole piece may include at least three spaced layers, preferably at least four layers. One or more of the layers of the pole piece may be shaped, in at least an region thereof surrounding the magnetic gap, so as to generally follow and guide the magnetic field lines emanating from the permanent magnet. A distributed mode vibrating panel loudspeaker comprising the moving coil drive unit arranged as an exciter is also disclosed. The distributed mode vibrating panel loudspeaker comprises a resonant member to be vibrationally excited in use and a backing frame supporting the resonant member. The exciter is supported by the backing frame and the coil assembly is mechanically coupled to the resonant member to be vibrationally excited in use.
    • 公开了一种用于将谐振元件激发成振动状态的移动线圈驱动单元。 动圈管驱动单元包括磁体组件和线圈组件,该线圈组件包括与磁体组件同心地布置的音圈,并且构造成使得音圈在使用中可相对于磁体组件轴向移动。 磁体组件包括永磁体和一个或多个极片。 磁体组件构造成提供环形磁隙,音圈悬挂在其中。 极片构造成具有包括至少两个间隔层的层压结构。 极片可以包括至少三个间隔开的层,优选地至少四层。 极片中的一个或多个层可以在其至少围绕磁隙的区域中成形,从而大致跟随并引导从永磁体发出的磁场线。 还公开了一种分布式振动面板扬声器,其包括设置为励磁机的动圈式驱动单元。 分布式振动面板扬声器包括在使用中被振动激励的共振构件和支撑谐振构件的背衬框架。 励磁机由背衬框架支撑,并且线圈组件机械耦合到共振构件以在使用中被振动激励。
