Still include a callus on the sole, a callus on the sole locates the second spring bottom. The noise brought by the desktop can be further buffered and eliminated, and the desktop and the second spring are protected. And a spring sleeve for accommodating the second spring is arranged at the bottom of the shell. The spring sleeve can play a role in positioning and protecting the second spring. A positioning piece for positioning the artificial mouth is arranged in the shell and close to the opening. The setting element can be fixed a position artifical mouth in fixed position, the loudspeaker of artifical mouth can be in accurate position, and avoid the collision to bring the noise. The sound insulating material surrounds the positioning member. Therefore, the sound conduction between the shell and the artificial mouth can be isolated, and the sound insulation effect can be further enhanced. The compressing assembly comprises a telescopic rod and a pressing rod, one end of the pressing rod is connected with the top of the telescopic rod around a horizontal shaft hinge, and the other end of the pressing rod extends to the upper part of the opening. The compressing assembly is simple in structure, the stethoscope can be removed and compressed only by lifting the compression rod, and the operation is convenient.

An artificial mouth device, includes artificial mouth, its characterized in that: still include above-mentioned artifical mouth noise reduction device. Such an artificial mouth device can obtain accurate sound without being affected by external noise.

Therefore, the problems that when a traditional artificial mouth is used for testing a stethoscope, the auscultation surface is tightly attached to the loudspeaker of the artificial mouth, external noise is transmitted to the loudspeaker from the outside of the artificial mouth, the sound of the artificial mouth is transmitted to the outside, interference is brought to performance testing of the stethoscope, and a testing result is inaccurate can be effectively solved.
