    • An inertially balanced miniature passive radiator full-range loudspeaker system is disclosed. In one embodiment the speaker system is a two-way system with low and high frequency components, where the low-frequency component is comprised of one active transducer and two passive radiators and the frequency range for this component is not outside of 10 Hz to 500 Hz. The low and high frequency components are individually optimized for operation in low and high frequency ranges respectively. By placing the passive radiators on opposing sides of an enclosure of the speaker system, the momentum generated by the motion of each of the passive radiators substantially cancels when the passive radiators are in phase. A passive radiators may be fitted with a voice-coil electrically connected to a corresponding voice-coil on the other passive radiator in a pair such that the generated back EMF resists out of phase motion of the passive radiators.
    • 公开了一种惯性平衡微型无源辐射器全频扬声器系统。 在一个实施例中,扬声器系统是具有低和高频分量的双向系统,其中低频分量由一个有源换能器和两个无源辐射器组成,并且该分量的频率范围不在10Hz至500之间 赫兹。 低频和高频分量分别针对低频和高频范围进行了优化。 通过将无源辐射器放置在扬声器系统的外壳的相对侧上,当无源辐射器处于同相时,由每个无源辐射器的运动产生的动量基本抵消。 无源辐射器可以安装有一个音圈,其电连接到另一无源辐射器上的对应音圈,使得所生成的反电动势抵抗无源辐射器的异相运动。
