Patent ID: 8331587

Claim:
A thermoacoustic module comprising: a substrate; at least one first electrode and at least one second electrode located on the substrate; at least one first conductive bonding layer located on the at least one first electrode, at least one second conductive bonding layer located on the at least one second electrode; and a sound wave generator spanning between, electrically connected to, and supported by the at least one first electrode and the at least one second electrode; wherein the sound wave generator is spaced from the substrate and embedded in both the at least one first and the at least one second conductive bonding layers, the at least one first and the at least one second conductive bonding layers are infiltrated into the sound wave generator and fix the sound wave generator to the at least one first electrode and the at least one second electrode; wherein the sound wave generator is capable of generating sound by converting electrical signal into heat, transferring the heat to the medium, and causing a thermoacoustic effect.
