    • An improved electrodynamic acoustic transducer eliminates or reduces the need for flexible or elastic materials to suspend an internal magnetic element by using both static and dynamic signal-dependent magnetic fields to control its movement. In one implementation, the transducer has a magnet that moves within a surrounding tube. This tube in turn supports one or more electromagnetic coils that generate a dynamic signal-dependent magnetic field that causes the internal magnetic element to vibrate. The surrounding tube also supports one or more magnets whose location on the tube is fixed and whose magnetic fields provide appropriate restoring forces acting on the internal magnetic element. These fixed magnets may be replaced or supplemented by ferromagnetic materials. This transducer may provide sound and infrasonic vibration by coupling the internal magnetic element to other radiating elements or by being placed in close proximity to or in actual contact with the pinna or meatus of the human ear when used in headphones or earphones, for example, and it also may provide sound through the direct vibration of the air in contact with the surface of the internal magnetic element. When direct atmospheric coupling is not required, the transducer may be assembled in a sealed enclosure.
    • 改进的电动声学换能器通过使用静态和动态信号相关磁场来控制其运动来消除或减少对柔性或弹性材料悬挂内部磁性元件的需要。 在一个实施方案中,换能器具有在周围管内移动的磁体。 该管又支持一个或多个电磁线圈,其产生导致内部磁性元件振动的动态信号相关磁场。 周围管还支撑一个或多个磁体,其位于管上的位置是固定的,并且其磁场提供作用在内部磁性元件上的合适的恢复力。 这些固定磁体可以被铁磁材料代替或补充。 该传感器可以通过将内部磁性元件耦合到其它辐射元件或者当用于耳机或耳机时被放置在与人耳的耳廓或耳道紧密接触或实际接触的位置时,提供声音和次声振动,例如, 也可以通过与内部磁性元件的表面接触的空气的直接振动来提供声音。 当不需要直接大气耦合时,传感器可以组装在密封的外壳中。
