[0003] However, existing stethoscopes have some drawbacks in use, such as:

[0004] 1. Traditional stethoscopes require doctors to place the stethoscope head on the human body based on experience, and then move the stethoscope head continuously during the auscultation to find the location of the organ emitting sound. This method of finding the sound source is not intuitive enough, making it difficult for doctors to accurately find the location of the sound source during auscultation, which affects the doctor's judgment of the results.

[0005] 2. The clarity of sound heard by a stethoscope is related to the size of the contact area between the stethoscope head and the human body.
