Problems solved by technology

Generally speaking, when the diameter of the sound-collecting surface is between 38mm-41mm, the effect of collecting sound is the best. In the prior art, when listening to different audio frequencies, it is realized by reducing the diameter of the sound-collecting surface, but reducing the diameter of the sound-collecting surface A larger diameter will result in a lower volume of the sound heard, especially when listening to small sounds, which may easily lead to misjudgment by the user

Abstract

The invention relates to a listening head matching structure of a stethoscope, in particular to a stethoscope head matching structure which can improve organ sound listening definition and improve thesound listening effect. The stethoscope head matching structure comprises a listening head body, a vibrating diaphragm and a fixing part, wherein a sound leading hole is formed in the listening headbody; the fixing part is provided with an axial through hole, a fixing part side wall for matched fixation with the listening head body and a diaphragm press part closely fit with the listening head body; the vibrating diaphragm is placed between the diaphragm press part and the listening head body, the vibrating diaphragm comprises an upper surface and a lower surface, a sound increasing ring isarranged between the vibrating diaphragm and the listening head body and / or between the vibrating diaphragm and the diaphragm press part, and at least part of the sound increasing ring is located on the outer side of the through hole of the fixing part. The listening head matching structure has the advantages of improving sound conduction capacity and improving the volume and definition of listened organ audios.

Description

technical field [0001] The invention relates to a stethoscope listening head fitting structure, in particular to a stethoscope listening head fitting structure which can improve the sound clarity of listening organs and the macro brightness to improve the listening effect. Background technique [0002] The existing stethoscope earpiece matching structure includes an earpiece body, a vibrating membrane and a fixing piece, and the vibrating membrane is fixed on the listening piece body by the fixing piece. [0003] In the prior art, the vibrating membrane is significantly bent, such as increasing the convex height and tension of the vibrating membrane to improve the listening effect. Although the convex vibrating membrane increases the contact surface between the vibrating membrane and the listening place during auscultation, there is It is beneficial to the collection of audio, but the convex structure of the vibrating membrane makes the surface of the vibrating membrane fo...
