Patented designs of vibrating diaphragm and sound-collecting cavity (patent number: 200520122864. 7 and 200520122862. 8) feature the most valuable effect. When performing auscultation for patients, doctors can get and compare two different sound of high and low tune with the same chest piece cover simply by adjusting the force on the stethoscope so as to obtain more efficient diagnostic basis.
