摘要： An earbud for detecting biosignals from and presenting audio signals at an inner ear canal and method therefor are disclosed. The earbud includes a nozzle and a housing including a body. The nozzle extends from the housing body and has a proximal end arranged for positioning within an inner ear canal of an individual. An earbud tip of the earbud attaches to the proximal end of the nozzle and is adapted to engage the inner ear canal. The earbud includes a speaker and various sensors including an infrasonic/vibration sensor. The infrasonic/vibration sensor detects the biosignals including infrasonic signals from the body of the individual in the canal, and the speaker transmits sound from an audio source into the canal via the nozzle. The earbud preferably seals the inner ear canal to block external sound while also decreasing an acoustic volume of the canal that amplifies the biosignals prior to detection.

摘要： A microphone includes a sensing element having two opposing sides; and a housing including a first acoustic port having an external-facing portion defined in part by a first aperture located on a first housing side and an internal-facing portion defined in part by a first cavity within the housing, the first cavity being coupled to a first side of the element; and a second acoustic port having an external-facing portion defined in part by a second aperture located on the first housing side and an internal-facing portion defined in part by a second cavity within the housing, the second cavity being coupled to a second side of the element. The ports are spaced apart at a distance such that a level of an electrical response by the element to an ambient acoustic noise at 50 dB A-weighted sound pressure level exceeds an internal electrical noise level of the element.

摘要： A system and method for leak correction and normalization of in-ear pressure measurement for hemodynamic monitoring are disclosed. The system includes an acoustical assembly and a data analysis system. The acoustical assembly includes an earbud system that forms an earbud seal with an ear canal of an individual, where the earbud system includes an earbud with an in-ear acoustic sensor that detects acoustic signals in the ear canal. The acoustic signals include audible signals and infrasonic signals. The data analysis system receives the acoustic signals from the earbud system, identifies hemodynamic pressure signals from a body of the individual included within the infrasonic signals, and identifies signal characteristics of the pressure signals over time. The data analysis system can then correct the hemodynamic pressure signals for effects caused by leaks in the earbud seal based upon changes to the signal characteristics over time.

摘要： A flextensional transducer for use in surface ship applications requiring the capability of withstanding underwater explosive shock is described. The transducer includes a plurality of ceramic stacked drivers disposed between an elliptical outer shell having opposing slots disposed along an inner surface of the shell and a flextensional limiting support block. The drivers are mounted on ball joint sockets which allow pivoting during high acceleration loading conditions. The support block further has a pair of curved surfaces which will generally follow, in close proximity, the inner surface of the shell and a member coupled to the opposing slots of the elliptical shell. The block can be fixed to a rigid mount disposed over at least one end of the transducer using a plurality of tie rods.

摘要： A vibroacoustic earbud (“earbud”) is proposed that includes a housing and an infrasonic/vibration sensor. The housing includes a nozzle with a nozzle tip that is configured for positioning within an ear canal of an individual. The sensor is included within the nozzle and detects biosignals including infrasonic signals from a body of the individual in the ear canal. The nozzle tip engages with a wall of the ear canal to provide an earbud seal, the result of which forms an ear canal acoustic volume that amplifies the biosignals. The earbud is tuned/designed to minimize loss of amplitude of the biosignals detected by the sensor in the ear canal acoustic volume when an unintentional leak occurs in the earbud seal that possibly reduces acoustic pressure in the ear canal acoustic volume.
