Patent ID: 7998091

Claim:
A bioacoustic sensor, comprising: a housing comprising an interfacing portion configured to establish coupling with a body part during use; a transducer assembly comprising: a transducer element coupled to the interfacing portion of the housing and configured to sense sound within a frequency range produced by matter of biological orgin, the transducer element configured to modulate or generate a signal in response to deformation of the transducer element; and a mass element compliantly coupled to a surface of the transducer element, the mass element positioned to improve the sensitivity of the transducer element in the frequency range, such that the transducer element includes a substantially uniform broadband improved sensitivity in the frequency range, wherein the transducer assembly is mounted on the inner surface of the interfacing portion within the housing so that the transducer element is preferentially sensitive to bioacoustic energy transmitted to the transducer element via the interfacing portion; and one or more conductors coupled to the transducer element.
