ACOUSTIC TRANSDUCERS WITH DYNAMIC FREQUENCY RANGE |
摘要 |
In one aspect, an apparatus for use downhole is provided, which apparatus, in one embodiment, includes an acoustic transducer having a first member in pressure communication with a confined fluid, wherein a displacement of the first member causes a volume change in the confined fluid that amplifies displacement of a second member to generate a pressure wave in medium. |
