Abstract
Abstract The manikin audio system described is an audio simulation system in which it is not necessary to have the audio signals emanating directly from a physical area under auscultation, but in which the proper sound is acoustically coupled to the ears of a listener when a particular region of the manikin is explored. The audio simulation system comprises a synthetoscope having a transducer and a contact portion which activates one of a plurality of responsive means within the manikin. Each of the responsive means selects an associated one of a plurality of stored signals and couples the selected signal to a transducer located within the synthetoscope to provide a high quality audio signal.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
39 words
Audio system for a manikin comprising: signal producing means; a synthetoscope coupled to said signal means; and means within said manikin responsive to said synthetoscope to select one of a plurality of signals stored in said signal producing means.
Claim 2
Dependent Claim
39 words
Audio system for a manikin comprising: signal producing means; a synthetoscope coupled to said signal means; and means within said manikin responsive to said synthetoscope to select one of a plurality of signals stored in said signal producing means.
Claim 3
Dependent Claim
22 words
The system of claim 1 wherein said synthetoscope includes a transducer coupled to receive said selected signal and produce an audio signal.
Claim 4
Dependent Claim
26 words
The system of claim 1 wherein said response means includes a plurality of switches which are individually activated by said synthetoscope to select said one Signal.
Claim 5
Dependent Claim
24 words
The system of claim 1 wherein said synthetoscope includes a conductive probe to contact one of a plurality of predetermined areas on said manikin.
Claim 6
Dependent Claim
40 words
The system of claim 4 including: an oscillator coupled to said probe; detector means capacitively coupled to said oscillator; and means responsive to the output of said detector means to select said one signal associated with the one predetermined area.
Claim 7
Dependent Claim
36 words
The system of claim 5 wherein said signal producing means includes an amplifier having its input coupled to said selected one signal and being biased by the output of said detector means to control its gain.
Claim 8
Dependent Claim
40 words
The system of claim 6 including a transducer position within said conductive probe to produce an output representative of the pressure applied by said probe on said manikin, said output being coupled to said amplifier to control its frequency response.
Claim 9
Dependent Claim
21 words
The system of claim 1 including a library of stored signal information which is selectively transferable to said signal producing means.
Claim 10
Dependent Claim
20 words
The system of claim 1 wherein said signal producing means is operated in a predetermined synchronism with said manikin operation.
Claim 11
Dependent Claim
43 words
A manikin audio system comprising: means for storing and producing at least one of a plurality of signals; a synthetoscope coupled to receive said one signal; and responsive means within said manikin and activated by said synthetoscope to select said one stored signal.
Claim 12
Dependent Claim
43 words
A manikin audio system comprising: means for storing and producing at least one of a plurality of signals; a synthetoscope coupled to receive said one signal; and responsive means within said manikin and activated by said synthetoscope to select said one stored signal.
Claim 13
Dependent Claim
18 words
The system of claim 10 including means to proportionally combine at least two of said plurality of signals.
