1. A device for detecting physiological sounds, the device comprising:
a thin film; and
a conductive element configured to conduct the physiological sounds to the thin film when contacting a skin of a live being;
wherein the conductive element comprises a first conductive element and a second conductive element, the first conductive element is located on the thin film and protrudes relative to the thin film, the second conductive element is in a ring shape and disposed around the first conductive element, the height of the second conductive element is equal to that of the first conductive element, and the first conductive element is sealed in a space formed by the second conductive element when the conductive element contacts the skin of the live being so as to reduce an interference from an outside.
