Transducer for sensing actual or simulated body sounds
First Claim
1. A system for simulating listening to body sounds comprising:
- An audio signal generation means that produces an electronic audio signal;
An electrically conductive electrode;
An electrically conductive body;
An electrical voltage or electrical field sensor;
An audio reproduction means to convert electrical audio signal detected by said sensor to acoustic signals;
wherein said audio signal generation means is electrically connected to said electrically conductive electrode, which is in turn electrically connected to electrically conductive body such that said electronic audio signal is conducted into said body, such that placing said sensor in close proximity to said body results in the detection of said electronic audio signal from said body to said sensor and converted to an acoustic sound by said audio reproduction means such that signal from said audio signal generation means is audible via said audio reproduction means.

Abstract
A transducer system is disclosed for detecting actual or simulated body sounds. An audio signal generation and detection system is disclosed for the purposes of simulating the medical examination of a patient or simulating the listening of sounds seeming to emanate from a live or inanimate body. A signal generator sets up a voltage potential at an electrode physically attached to the body, or electrically connected to a body, thereby setting up a voltage potential on a surface area of the body. An electric field potential sensor or a capacitive electrical sensor placed in proximity to the electrode or body surface then detects the voltage potential. The signals produced by the signal generator can represent heart, lung, bowel or other sounds and the electrical sensor can take the physical form of a listening device such as a stethoscope, thereby creating a simulation of listening to body sounds for medical diagnostic purposes.
