Development of Lightweight Portable Loudspeaker.

Abstract

This document covers the technical details of work performed to develop a lightweight portable loudspeaker to be worn on the epaulet or pocket of the person carrying a backpack radio. The amplifier contained in the case is powered by the X-mode output of the PRC-70 and other field radios. The loudspeaker supplies approximately 85 dB SPL at one meter and is able to withstand severe environment.
