This creation is related to the technical field of biological sound collection and application, especially a sound collection system of living body organs.

The frequency range of sound waves that humans can feel is about 20 to 200 hertz (Hz). Since there are subtle and rhythmic sounds in the operation of various parts of the human body, the frequency is generally 2 to 16 Hz, such as 8 to 12 Hz for the head and 12 Hz for the internal organs. 4 ~ 6Hz and so on. Stethoscope is a very important instrument in the medical field. It can hear the sounds of organs such as the heart and lungs in the human body. The purpose is to check whether the normal human body mechanism in the body has any disease.

Traditional acoustic stethoscopes can only transmit weak sounds through the air. Therefore, it is difficult for doctors to detect small changes in the sound of the patient's internal organs during auscultation, which brings great difficulties to auscultation. Moreover, traditional auscultation cannot share, save, and objectively analyze and evaluate auscultation signals, and it is difficult for sound signals to be shared among multiple doctors in real time.

Therefore, a new type of electronic stethoscope was later developed. Its principle adopts the sound-electricity/electro-acoustic conversion method, and the patient or user's organ sounds of different parts are collected into the device in real time, which can be repeated repeatedly. And send it to the system platform of monitoring collection summary/diagnosis at any time. For doctors to effectively judge the physical information of the collected person, and give appropriate treatment if necessary. Although the existing electronic stethoscope can amplify the collected body sounds and save the auscultation data of the person being auscultated, it is beneficial to trace the historical health status and determine the change of the condition, but the practical application still cannot avoid environmental clutter. technical problems of interference and sound distortion.

Furthermore, the overall structural design of the existing conventional electronic stethoscopes is still not perfect, and most of them maintain the appearance of the traditional stethoscopes, so that the use is greatly restricted and cannot effectively provide wider applications.
