铁磁流体换能器的工作原理及其宽带辐射响应的特性

The principle of ferrofluid transducer and the character of wide band transmitting response

本文阐明了铁磁流体的基本特性,及其构成换能器的转换机理。它能获得4个倍频程以上的低频宽带发射响应。并指出它在水声技术中的应用前景。

This paper describes the fundamental characters of ferrefluid, and the transducing mechanism of ferrofluid transducers. Ferrofluid transducer may work in four or more octaves of wide band transmitting in the low frequency range. It is pointed out the application in underwater acoustic technique.
