A mechanical resonator (100) for a thermoacoustic device (102) having a compressible fluid (104) contained within a housing (106),the housing having a pair of heat exchangers (108, 110) and a thermodnamic medium (112) therebetween. The resonator (100) includes a member (114) for mimicking dynamic conditions at a position of the housing (106); and a linear suspension element (116) suspending the member (114) in the housing (106). The mechanical resonator saves length and eliminates high-velocity flow losses. A transducer may also be mounted with the mechanical resonator to derive power in another form from the system, for example, electricity, or introduce power into the system. In combination, the transducer and mechanical resonator allow for cool-side driving of a thermoacoustic system. |
