Patent ID: 8306246

Claim:
A thermoacoustic device comprising: a first conductive element defining a plurality of first conductive holes spaced from each other; a second conductive element defining a plurality of second conductive holes spaced from each other; a plurality of first electrodes having first ends and second ends opposite to the first ends, and the first ends of the first electrodes received in the first conductive holes in a one-to-one manner and electrically connected to the first conductive element; a plurality of first insulators insulating the second ends of the first electrodes from the second conductive element; a plurality of second electrodes having third ends and fourth ends opposite to the third ends, and the third ends of the second electrodes received in the second conductive holes in a one-to-one manner and electrically connected to the second conductive element; a plurality of second insulators insulating the fourth ends of the second electrodes from the first conductive element; and a thermoacoustic film electrically connected to the first electrodes and the second electrodes.
