Description
Technical field
The utility model is related to Medical Devices, more particularly, to stethoscope.
Background technology
Stethoscopic sound conduction mainly passes through air transmitted and solid conduction.
In prior art, stethoscope improves the conduction of sound, generally by the tension force changing stethoscope diaphragm, or
Improve listening head body density, or improve the modes such as the sealing of rotating shaft and listening head body to realize, these modes are all passed through
Change the part of the air transmitted in hearing device conductive process.
How to reduce decay in solid conduction for the sound in stethoscope, and energy reduces cost, become industry urgently to be resolved hurrily
Technical barrier.
Utility model content
Goal of the invention of the present utility model is to disclose a kind of reduction loss in solid conduction for the sound, can reduce into again
This stethoscope head assembly.
Goal of the invention of the present utility model is achieved in that
A kind of stethoscope head assembly, including listening head body, collects sound body and rotating shaft；Described listening head body and described rotating shaft turn
Dynamic cooperation；The described sound body that collects is coordinated with described listening head body；The described sound body that collects is provided with the voice guide hole b that insertion collects sound body；Described turn
Axle is provided with axial voice guide hole a, and the side voice guide hole intersecting and communicating with described voice guide hole a；Described voice guide hole b and described side
Voice guide hole connects；The described sound body that collects is made up of the first density material, and described listening head body is made up of the second density material, described turn
Axle is made up of triple density material, and the second density material density and triple density density of material respectively less than the first density material are close
Degree.
Further, the second density material density is same or like with triple density density of material.
When sound conducts in different mounting mediums, because the impedance of different medium is different, lead to impedance discontinuity so that
Sound attenuating is quickly.Secondly, in the discontinuous interface of medium, there is refraction and reflect in sound wave to sound, lead to the loss of acoustic energy.When
When listening head body and rotating shaft adopt the preparation of equal densities material or the preparation of similar density material, can effectively reduce sound attenuating speed
Degree.
Wherein, described listening head body can be for integral type or split type.
Described listening head body with described collect sound body can be integrative-structure or split cooperation be fixedly connected.
Described voice guide hole a and described side voice guide hole and this body by integral forming of rotating shaft.
The utility model has the advantage that
1st, the utility model, by making the impedance of listening head body and rotating shaft continuous, reduces the loss of sound energy attenuation.
2nd, the utility model listening head body density of material and rotating shaft material density are low compared with the density of material collecting sound body, thus greatly
Width reduces cost.
3rd, the utility model, by making the impedance matching of listening head body and rotating shaft, slow down the speed of the decay of sound.
