AI Technical Summary

Technical Problem

Ultrasonic acoustic waveguides face challenges in operating effectively in extreme conditions such as high temperatures, radiation, and electromagnetic interference, as well as in corrosive environments, where they often suffer from energy loss and structural integrity issues.

Method used

A flexible metal rod acoustic waveguide design with rigidly attached cylindrical waveguides and conical acoustic concentrators, allowing for flexible positioning and hermetic sealing, and the use of a protective tube for added protection, enables efficient transmission and reception of ultrasonic signals across distances and through corrosive media.

Benefits of technology

This design enhances the operational capacity of acoustic waveguides by maintaining signal integrity and extending service life, even in harsh conditions, by allowing flexible placement and hermetic sealing, while minimizing energy loss and corrosion.

Abstract

An acoustic waveguide includes a flexible metal rod, to each end of which a cylindrical waveguide is rigidly attached through a conical acoustic concentrator, wherein one cylindrical waveguide being made for its attachment to an electroacoustic transducer, while the other cylindrical waveguide is made for its attachment to a receiving device for receiving acoustic oscillations. The design helps to increase the functional capabilities of the acoustic waveguide due to its use in devices operating in conditions of high temperature, radiation, strong electromagnetic inference and other negative factors.
