摘要： An acoustic-to-electrical transducer for sensing body sounds is disclosed. The transducer comprises a capacitive sensor, whereby a stethoscope diaphragm forms one plate of a capacitor, with the second plate of the capacitor being co-planar to the diaphragm. The capacitance of the two plates varies with the distance between them, said distance being modified by motion of the diaphragm in response to sound pressure. The sensor, circuitry, manufacturing methods and improvements are disclosed.

摘要： A chest piece for a stethoscope has a housing with a cavity. The cavity has a cavity surface which is paraboloid in shape, having an apex, an axis, and a focal point. The cavity terminates at the apex and an opening, and the focal point resides in the cavity. A transducer is positioned at the focal point. The parabolic shape of the cavity surface acts to reflect sound waves transmitted normal to the opening to the transducer, while reflecting other sound waves. A mechanical wave guide with a series of parallel passages preferably extends across the opening. Preferably, a membrane with a convex surface covers the opening. The cavity is preferably filled with a liquid or gel having physical characteristics similar to human flesh. To reduce noise from motion of the chest piece across the skin, the stethoscope can be activated by a pressure switch responsive to fluid pressure inside the cavity.

摘要： Physiological condition monitors utilizing very low frequency acoustic signals and signals indicative of body orientation are disclosed. The physiological condition monitors comprise a sensor that is capable of detecting low frequency acoustic signals in the frequency range of one tenth Hertz to thirty Hertz. The sensor comprises a chamber having portions that form a cavity and a low frequency microphone placed within the cavity. An alternate embodiment of the invention comprises a chamber having portions that form a resonant cavity, a microphone mounted in the resonant cavity, and a membrane that covers the resonant cavity. Low frequency acoustic signals that are incident on the membrane cause the membrane to move and amplify the acoustic signals within the resonant cavity. The sensor provides information concerning physiological conditions, such as respiration and cardiac activity. The sensor in a physiological condition monitor does not need to be directly coupled to the skin of the person being monitored. The physiological condition monitor simultaneously provides information concerning cardiac activity, and respiration activity, and the movement and position orientation of the monitored person's body.
