Many studies have dealt with the realisation of ionic transducers, the most famous remaining the ionophone. These transducers combine two effects, one related to a heat source, and the other corresponding to a force distributed in the volume of the ionized area. This paper gives some basic equations describing the acoustic field generated by these two effects in the case of a Corona discharge ; these show that each source predominates in a separate frequency range. These analytical results are compared with experiments, and show a good agreement.
