Abstract
An acoustic vibration sensor, also referred to as a speech sensing device, is provided. The acoustic vibration sensor receives speech signals of a human talker and, in response, generates electrical signals representative of human speech. The acoustic vibration sensor includes at least one diaphragm positioned adjacent to a front port and at least one coupler. The coupler couples a first set of signals to the diaphragm while isolating the diaphragm from the second set of signals. The coupler includes at least one material with acoustic impedance matched to the acoustic impedance of human skin.
Claims14
A sensor for generating electrical signals, comprising:
- at least one diaphragm positioned adjacent a front port;
- and
- at least one coupler configured to couple a first set of signals to the diaphragm and reject a second set of signals by isolating the diaphragm from the second set of signals, wherein the coupler includes at least one material having an acoustic impedance matched to an impedance of human skin.
An acoustic sensor, comprising:
- a first port on a first side of an enclosure;
- a second port on a second side of an enclosure;
- at least one diaphragm positioned between the first and second ports;
- and
- a contiguous coupler having a first portion that couples a first side of the diaphragm to skin of a human talker and a second portion that isolates the first side of the diaphragm from an airborne acoustic environment of the human talker, wherein the coupler includes at least one material having an acoustic impedance matched to the impedance of skin.
A communication system, comprising:
- at least one signal processor;
- and
- at least one acoustic sensor that couples electrical signals representative of human speech to the signal processor, the sensor including at least one diaphragm positioned between a first port and a second port of an enclosure, the sensor further including a contiguous coupler comprising at least one material having an acoustic impedance matched to the impedance of skin, wherein the coupler includes a first portion that couples a first side of the diaphragm to skin of a human talker and a second portion that isolates a first side of the diaphragm from an airborne acoustic environment of the human talker.
