[0007] 2.2 Since the entire vibrating membrane is made of two different materials with significantly different hardness, the acoustic impedance is different when the sound wave propagates due to the different hardness and density of the two materials. At this time, refraction or scattering will occur at the interface, and the refraction or scattering increases. Attenuation of sound waves
[0008] 2.3 Since the entire vibrating membrane is made of two different materials with significantly different hardness, the sound wave is propagated due to the different hardness and density of the two materials, and the sound wave affects the layering of the sound when it propagates through two different media, resulting in the sound being cloudy and unclear.

Abstract

The invention relates to a matching structure for a stethoscope head, in particular to a stethoscope head capable of clearly listening to multiple audios by adopting a single-sided stethoscope head body under the condition of not changing the size of a sound collection surface, a matching structure of the stethoscope head and a method for listening to multiple audios by adopting the matching structure. The multi-audio stethoscope head provided by the invention comprises a stethoscope head body, a vibrating diaphragm and fixing pieces, wherein a sound collecting surface is arranged on the stethoscope head body, and a sound guide hole is formed in the sound collecting surface; each fixing piece is provided with an axial through hole, a fixing piece side wall used for being matched and fixedly connected with the stethoscope head body and diaphragm pressing parts used for enabling the vibrating diaphragm to be tightly matched with the stethoscope head body; and the vibrating diaphragm is arranged between the diaphragm pressing parts and the stethoscope head body, the vibrating diaphragm is provided with an upper surface and a lower surface, convex columns are arranged on the parts, located on the inner sides of the through holes of the fixing pieces, of the sound collecting surface of the stethoscope body, and the highest points of the convex columns are positioned below the lowersurface of the vibrating diaphragm. The stethoscope head of the invention has the advantages that sound conduction capability can be improved in virtue of a single side, and volume and definition in listening to visceral organ audios are improved.

Description

technical field [0001] The invention relates to a multi-audio stethoscope earpiece and its matching structure, especially the single-sided stethoscope earpiece, which can be heard clearly without changing the size of the sound-collecting surface and without preparing a high-frequency sound collecting ring on the sound-collecting surface. A stethoscope earpiece for high-frequency sounds and its matching structure, and a method for listening to multiple audio frequencies by using the matching structure. 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] 1) The size of the sound collection cavity is greatly reduced when listening to multi-frequency sound on one side in the prior art, [0004] However, when a children's stethoscope listens to multi-frequency sounds by changing the size...
