Claims18
An acoustic sensor comprising:
- f) a body formed of a solid integral mass having a circular apron with two opposite major side walls,
- i. one side wall being concave in configuration and the other side wall having a rearwardly facing portion coaxially formed thereon, the rearwardly facing portion defining an attachment for a microphone;
- ii. an opening coaxially formed through the rearwardly facing portion;
- and
- iii. an annular edge connecting the periphery of the side walls;
- g) a microphone, attached to the rearwardly facing portion,
- wherein the microphone is configured to produce electrical signals in response to acoustic signals transmitted from an abdomen of a pregnant subject;
- h) a flexible membrane covering the one side wall, wherein the edge of the flexible membrane covers the annular edge of the one side wall,
- wherein the flexible membrane is configured to contact the skin of the human pregnant subject,
- wherein the flexible membrane is configured to transduce transmitted acoustic signals to the body;
- and
- wherein the body is configured to transmit the transduced acoustic signals to the microphone;
- i) an electrical conductor electrically connected to the microphone;
- and
- j) a connector in electrical contact with the electrical conductor for connection to a lead wire.
