A biological sound acquisition device (10) includes a housing (100), a first acceleration sensor (210), and a second acceleration sensor (220). The first acceleration sensor (210) is disposed in the housing (100). The first acceleration sensor (210) is mechanically connected to the housing (100) through a first vibration damping member (410). The second acceleration sensor (220) is disposed in the housing (100).

An automatic diagnostic apparatus and corresponding method is disclosed for recognizing heart sounds of interest, i.e., murmurs, detected in streaming audio data picked up by a stethoscope. Sensors included in the device capture audio data in real time during an auscultation exam performed by a physician. A feature vector that models the stream of audio data is created and supplied to a deep neural network stored on the diagnostic device. The deep neural network generates a probability for each of the heart sounds of interest. When the probability of detection exceeds a pre-established threshold value the device alerts the physician through visual and/or audio cues, enhancing the physician's diagnostic capability during routine examination.

The invention relates to a device for detecting physiological sounds, the device comprising a thin film, and a first conductive element for conducting sounds, the conductive element being located on the thin film. In some embodiments, the detection device comprises a cavity; the thin film is a part of the cavity. The volume of the cavity is variable; the volume of the cavity is reduced, either when the conductive element contacts the skin of a human or a mammal, or before the conductive element contacts the skin of a human or a mammal, or after the conductive element contacts the skin of a human or a mammal. The device of the inventions can significantly improve the detection sensitivity and resolution of physiological sounds, and can give early diagnosis pathological sounds, for example, heart failure can be detected by heart sound diagnosis.

An acoustic sensor is configured to provide accurate and robust measurement of bodily sounds under a variety of conditions, such as in noisy environments or in situations in which stress, strain, or movement may be imparted onto a sensor with respect to a patient. Embodiments of the sensor provide a conformable electrical shielding, as well as improved acoustic and mechanical coupling between the sensor and the measurement site.

A headphone and an electronic device are provided. The headphone includes a gyroscope, which senses a bone conduction vibration and provides a quadrature error signal for reflecting the bone conduction vibration. Specifically, the headphone includes a transmission assembly that acts directly or indirectly on the gyroscope or an inertial measurement unit (IMU) including the gyroscope. The transmission assembly transmits the bone conduction vibration to the gyroscope to make the gyroscope strain, thereby causing the quadrature error signal of the gyroscope to change to detect the bone conduction vibration with sensitivity.
