Sound detecting device for pelvic floor muscle exercise

A sound detecting device for pelvic floor muscle exercise, applied to receive low frequencies generated when the pelvic floor muscle is relaxed and contracted, characterized in including:

• a main body, having a base seat disposed therein and used for supporting;
• a sound collecting chamber, disposed in the main body and used for amplifying and collecting sounds for increasing the sensibility, wherein an opening having a sound receiving function is formed at a top end of the sound collecting chamber;
• an elastic sound receiving membrane, disposed in the main body and located at the opening of the sound collecting chamber, wherein the elastic sound receiving membrane covers on at a desired detecting location of an outer skin layer or an outfit or a skirt where the lower frequencies generated when the pelvic floor muscle is relaxed or contracted;
• a support ring, disposed at a top end of the main body, arranged at a periphery of the elastic sound receiving membrane and corresponding to an outer periphery of the opening of the sound collecting chamber, wherein a center of the support ring is formed with a middle hole allowing the elastic sound receiving membrane to be exposed;
• a microphone, disposed at a bottom end of the sound collecting chamber;
• and
• an electric circuit board, disposed on the base seat, used for providing a wave filtering function and an amplifying function, and connected to the microphone ;
• wherein, the elastic sound receiving membrane is downwardly pressed through a pressure supplied by the skin muscle weight for being in a recessed status so as to be tightly adjacent to the skin or the outfit or the skirt, thus the low frequencies generated through the vibrations caused by the pelvic floor muscle being contracted and relaxed are able to be amplified and precisely collected.
