Abstract
A thermoacoustic module includes a substrate, a sound wave generator, at least one first electrode and at least one second electrode. The substrate has a top surface, and the top surface defines at least one recess. The sound wave generator is located on the top surface of the substrate and includes at least one first region suspended above the at least one recess and at least one second region being in contact with the top surface of the substrate. The at least one first electrode and at least one second electrode are coupled to the sound wave generator.
Claims20
A thermoacoustic module, the thermoacoustic module comprising:
- a substrate having a top surface, and the top surface defining at least one recess;
- a sound wave generator comprising at least one first region suspended above the at least one recess and at least one second region in contact with the top surface of the substrate;
- and
- at least one first electrode and at least one second electrode coupled to the sound wave generator;
- wherein the sound wave generator is capable of generating sound by converting electrical signal into heat, transferring the heat to a medium, and causing a thermoacoustic effect.
A thermoacoustic device, the thermoacoustic device comprising:
- a thermoacoustic module comprising:
- a substrate comprising a top surface, and the top surface defining at least one recess;
- and
- a sound wave generator comprising at least one first region suspended above the at least one recess and at least one second region in contact with the top surface of the substrate;
- and
- an signal input device capable of transmitting signals to the sound wave generator;
- wherein the sound wave generator is capable of generating sound by converting electrical signal into heat, transferring the heat to a medium, and causing a thermoacoustic effect.
A thermoacoustic device, the thermoacoustic device comprising:
- a thermoacoustic module comprising:
- a substrate having a top surface and at least one recess;
- a sound wave generator comprising at least one first region suspended above the at least one recess and at least one second region in contact with the top surface of the substrate;
- at least one first electrode and at least one second electrode coupled to the sound wave generator;
- and
- a cover board;
- and
- two fixing frames, wherein the thermoacoustic module is located between the two fixing frames;
