Problems solved by technology

However, when the diaphragm is working, due to the different tension of the diaphragm (equivalent to the different elasticity of the drum surface), different wavelengths and different attenuation values ​​are obtained, which will affect the listening effect
[0005] In the process of manual assembly of stethoscopes, the hearing effect of the assembled stethoscopes is different due to different people. Even the same person cannot guarantee the same assembly. Therefore, how to make the diaphragm work in the best working condition has always been a problem in the industry.

Abstract

The invention relates to fittings of an auscultator, in particular to a structural component for fixing an auscultator head and a fixing part. The structural component comprises the auscultator head and the fixing part, wherein a rotating shaft hole, a sound guiding hole which are communicated with each other and and a sound collecting surface, are formed on the auscultator head; a through hole and a semi-through hole, of which the axes are superposed and the pore diameters are different, are formed along the axis of the fixing part; an annular step is formed on the auscultator head on one side of the sound collecting surface, and at least comprises an annular first side edge, a first bottom edge and an annular second side edge; the first side edge and the second side edge are connected with each other through the first bottom edge; the fixing part is matched and fixed with the annular step. The structural component has the advantages that the consistency of products is high; the sound hearing effect is excellent.

Description

technical field [0001] The invention relates to a medical device accessory, in particular to a stethoscope accessory, specifically a matching structural assembly of a stethoscope earpiece body and a fixing piece and a method for adjusting a diaphragm in the stethoscope to a predetermined tension using the structure. [0002] Background technique [0003] A stethoscope is assembled from multiple parts, mainly including a diaphragm, a listening head body, a fixing piece, a rotating shaft, a rubber tube and an earhook. When in use, the diaphragm is fixed on the listening head body through the fixing piece, and the diaphragm and the listening head body form a sound collecting cavity, and the sound of the organs is amplified in the sound collecting cavity through the diaphragm, and is connected to the listening head body The rotating shaft is transmitted to the rubber tube, and then transmitted to the earhook through the rubber tube for the user to listen to. Thus the diaphragm...
