| 主权项 | 1. A balanced electromagnetic transducer, comprising: first and second components connected together by a flexible component, at least a part of the flexible component flexes upon exposure of the transducer to energy, wherein the transducer is configured to generate static magnetic flux that passes from the first component to the second component via the flexible component and that travels across no more than two air gaps, wherein the balanced electromagnetic transducer is an actuator; the balanced electromagnetic transducer is configured to generate a dynamic magnetic flux, and the balanced electromagnetic transducer is configured such that the static magnetic flux and the dynamic magnetic flux interact across two air gaps, both of which have a span that varies during actuation of the actuator, thereby actuating the actuator. | ||
