The body comprises a shell with at least one hole and a side with a sound hole. The shell defines a sound cavity in the body. The thermoelectric converter, disposed around at least a part of the shell, comprises a circuit and a conductive membrane and covers at least a part of the at least one hole. The circuit receives at least one electrical audio signal. The conductive membrane contacts a part of the circuit so that the thermoelectric converter heats air in the sound cavity to emit sound."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Thermal acoustic speaker","description":"A thermal acoustic speaker comprises a body and a thermoelectric converter.
