Problems solved by technology

[0004] Because the outer edge 23 of the vibrating membrane 2 is fixed, and the central part 24 of the vibrating membrane 2 protrudes, the center of the lower surface 22 of the vibrating membrane 2 is pressed by the ring-shaped protrusion 13, and the edge 23 of the vibrating membrane 2 is pressed down, so that the vibrating membrane 2. The upper surface 21 becomes arched, and the shape of the vibrating membrane 2 changes. After the vibrating membrane 2 changes from a flat membrane to an arched membrane, the performance of the vibrating membrane 2 changes, thereby destroying the original sound transmission of the vibrating membrane 2. performance, causing the audio volume and clarity to drop significantly
[0005] Secondly, because the edge 23 of the vibrating membrane 2 is compressed, the vibration of the vibrating membrane 2 is limited. Since the sound is transmitted through vibration, the vibration of the vibrating membrane is limited, which also leads to the weakening of the sound transmission capacity.

Abstract

The invention relates to a stethoscope head matching structure, in particular to a stethoscope head matching structure capable of improving sound clarity of listening visceral organs and improving listening effect. The stethoscope head matching structure comprises a head body, a vibrating membrane and fixing parts; the vibrating membrane is a flat membrane, and each fixing part is provided with anaxial through hole, a fixing part side wall and a membrane pressing part; the vibrating membrane is arranged between the membrane pressing parts and the head body and has an upper surface and a lowersurface, a sound enhancement ring is arranged at least between the vibrating membrane and the head body and between the vibrating membrane and the membrane pressing parts, the sound enhancement ringis connected with the upper surface or the lower surface of the vibrating membrane to form a joint part, the joint part is located between the axial extending surfaces of the side wall of the throughholes and the side walls of the fixing parts or the axial extending surfaces of the side walls of the fixing parts, and the vibrating membrane does not bend after being fixedly connected with the fixing part. The stethoscope head matching structure has the advantages of improving sound conduction capacity and increasing sound volume and clarity of listening visceral organ audio.

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. In the prior art, the listening effect is improved by increasing the convex height and tightness of the diaphragm. Although the convex diaphragm increases the contact surface between the diaphragm and the listening place during auscultation, which is beneficial to audio collection, the vibration The convex structure of the diaphragm makes the surface of the diaphragm form an arch with strong support, and the outer edge of the diaphragm is fixed by fixtures. The macro brig...
