Transducer with the Direct D/A Conversion Using Optoacoustic Principle

Original language description

Transducers with the direct D/A conversion, sometimes called digital transducers, either loudspeakers or earphones, are searching their ways into being. There have been several attempts to design such devices, but none of them left research laboratoriesand made its way to commercial use yet. Most of them use "classical" electroacoustic transduction principles, i.e. electrodynamic or electrostatic. In this article the possibility to use opto-acoustic transduction principle is explored. First, the principles of physical phenomena used in this transducer are revised. Then, some construction details in light of their usage in the digital earphone are described.
