Description

pickup diaphragm

This creation relates to a sound pickup diaphragm, which is an audio receiving element used for being sleeved on an auscultation head.

In the conventional technology, the pickup device is used to receive the physiological sound of the human body, and it is called a stethoscope when used in medical applications. Among them, there are relatively old wired stethoscopes and wireless electronic stethoscopes, whether it is the wired stethoscope or the wireless electronic Most of the stethoscopes are equipped with contact-type microphones inside, and when the stethoscope is in contact with the human body, the sound is collected/picked up.

The conventional stethoscope contacting the sound pickup element with the human body will be sleeved with a flat diaphragm. During the sound collection/picking process, the plane of the flat diaphragm in contact with the human body is only for the purpose of receiving audio. Audio has many subtle vibrations, and the flat diaphragm cannot fully receive it effectively because of its low sensitivity.

The pickup diaphragm of this creation combines at least two designs of different materials and shapes, and uses the relative linkage relationship between different materials and shapes to make the movement between the two highly flexible, so as to improve the accuracy of the pickup process. The sensitivity of the vibration reception of subtle audio, so this is the solution for the original creation of the pickup diaphragm.
