摘要

一种新的基于金属带设计的空气耦合换能器已被开发和测试。在稀土磁铁和一组极片提供的磁场中，薄带处于张力下。该装置可以作为空气中超声波频率的源或接收器，具有合理的带宽。

A new design of ultrasonic air-coupled ribbon transducer

A new design of air-coupled transducer has been developed and tested, based on a metallic ribbon design. The thin ribbon is held under tension within a magnetic field provided by rare-earth magnets and a set of pole pieces. The device can act as a source or receiver at ultrasonic frequencies in air, with reasonable bandwidths.
