摘要：Thermoacoustic engines and coolers are a promising emerging technology due to its environmental friendliness and the lack of mechanical moving parts. Acoustic-to-electrical (or vice versa) transduction devices are the key components allowing for the conversion between acoustic (i.e. mechanical) and electrical energies (or vice versa). Some of researchers investigated the use of acoustic drivers in their devices due to their high acoustic power and transduction efficiency. This paper focuses on the performance analysis of a few selected acoustic drivers, available commercially, in order to provide a better understanding of their efficient utilisation in the context of coupling with thermoacoustic machines (engines or refrigerators). Six different acoustic drivers where studied using analytical solutions. The selected drivers have widely varied specifications which leads to major differences (in terms of ultimate performance) when various acoustic conditions are applied to simulate the presence of different thermoacoustic networks. Such investigation could lead to better engineering practices in coupling the drivers to thermoacoustic systems and positively influence their overall efficiency. Therefore, this study is thought to be beneficial design engineers working on thermoacoustic machines.
