Abstract
The invention discloses gas-liquid combined sealing sound arrester, including air bag and liquid capsule is provided, the liquid capsule is sleeved in air bag, and the air bag and liquid capsule are annular sealing member.As a result, using air bag as sound insulation outer layer, sound-insulating inner layer is acted on liquid capsule, after noise enters liquid capsule after the air bag of outer layer, acoustic wave energy can play good soundproof effect by reflection, absorption and scattering.On the one hand the gas-liquid combined sealing sound arrester of the present invention avoids the accuracy of the interference effect test result of noise, on the other hand improve the comfort of subject during the test.Due to the convenience and validity of the invention, can well spread in the various mechanisms using hearing test.
Description
Technical field
The present invention relates to a kind of sound arrester, more particularly to gas-liquid combined sealing sound arrester.
Background technology
Hearing test is that most conventional and most important inspection item, result can reflect the journey of hearing loss in otology outpatient service
The position of degree, property and lesion is widely used on the clinic diagnosis such as ear-nose-throat department and experience.In order to meet huge at present face
Bed demand, various hospital outpatients are tested and have all opened up hearing test project with center, rehabilitation institution, using it is most be exactly pure tone
Test, pure tone test need pure tone audiometer, test earphone and sound insulation environment.It is exactly to press that wherein test earphone is most common
Aural headphone and cover aural headphone, there is no the effects of sound insulation for these earphones, although entire test process is usually in soundproof room
Middle progress, but any sound, such as the rustle of clothes friction sent out inside soundproof room etc. can all become quite apparent,
This may allow subject that cannot preferably cool it during the test, need the conversion for avoiding posture, breathing and saliva
The problems such as swallowing.Although thus the soundproof room sound source external to it preferably obstructs, sound is sent out then without effect to inside.
Invention content
In view of a little, the present invention provides one kind to add on routine test earphone or earmuff, forms confined space and increases
To the gas-liquid combined sealing sound arrester of the buffer action of external noise.
According to an aspect of the invention, there is provided gas-liquid combined sealing sound arrester, including air bag and liquid capsule,
The liquid capsule is sleeved in air bag, and the air bag and liquid capsule are annular sealing member.As a result, using air bag as every
Sound outer layer acts on sound-insulating inner layer with liquid capsule, and after noise enters liquid capsule after the air bag of outer layer, acoustic wave energy is anti-
It penetrates, absorb and scatters, good soundproof effect can be played.
In some embodiments, gas-liquid combined sealing sound arrester further includes support column, and the support column is located at sky
In air bag, one end of the support column is fixedly connected with air bag, and the other end of the support column is fixedly connected with liquid capsule.By
This, the sustainable relative position between positioning air bag and liquid capsule of support column.
In some embodiments, the inside filling of a diameter of 18~22mm of air bag, the air bag are full dry empty
Gas.
In some embodiments, a diameter of 8~12mm of the liquid capsule, the inside of the liquid capsule, which is filled with, contains stone
The silicon oil solution of sand.
In some embodiments, the wall thickness of the air bag and liquid capsule is 0.8~1.2mm.
The beneficial effects of the invention are as follows：On the one hand the accuracy of the interference effect test result of noise is avoided, on the other hand
Improve the comfort of subject during the test.Due to the convenience and validity of the invention, can spread to well each
Kind is using in the mechanism of hearing test.
Description of the drawings
Fig. 1 is the structural schematic diagram of the gas-liquid combined sealing sound arrester of an embodiment of the present invention；
Fig. 2 is the sound insulation principle schematic of gas-liquid combined sealing sound arrester shown in Fig. 1.
Specific implementation mode
The invention will now be described in further detail with reference to the accompanying drawings.
Fig. 1 and Fig. 2 schematically shows a kind of gas-liquid combined sealing sound insulation dress of embodiment according to the present invention
It sets.
As shown in Figure 1, gas-liquid combined sealing sound arrester includes air bag 1, liquid capsule 2 and support column 3, liquid capsule 2
It is sleeved in air bag 1, air bag 1 and liquid capsule 2 are annular sealing member.
The appearance of the present apparatus is a flexible organic silica gel material sleeve, can be sleeved on the edge of conductance earphone, this
Device can also be customized according to the earmuff of used conductance earphone model or other specifications, according to the side of installed equipment
Edge size produces the side set met, makes it that can securely be placed on installed equipment.
Support column 3 is located in air bag 1, and one end of support column 3 is fixedly connected with air bag 1, the other end of support column 3 with
Liquid capsule 2 is fixedly connected.A symmetrical supporting pillar 3 is respectively set inside and outside between liquid capsule 2 to connect with the inner wall of air bag 1,
It can keep the stationarity of relative position between air bag 1 and liquid capsule 2.Supporting pillar 3 may be set to be multigroup, and supporting pillar 3 is adopted
It is made of solid silica gel material.
Air bag 1 is annular organic silica gel seal tube, and the diameter of air bag 1 can be 18~22mm, air bag 1 it is interior
The full dry air of portion's filling.When earphone is pressed on subject's face, due to the flowability of air, keep the edge of silica gel sheath close
Ground forms closed space in docile and skin, prevents the incoming of sound and ensures the comfort worn.
Liquid capsule 2 is ring packing organic silica gel hose, and the diameter of liquid capsule 2 can be 8~12mm, liquid capsule 2 it is interior
Portion's filling silicon oil solution, silicon oil solution contain the quartz sand that weight ratio is 0.5%.When noise enters after the air bag of outer layer
Liquid capsule, acoustic wave energy play good soundproof effect by reflection, absorption and scattering.
The wall thickness of air bag 1 and liquid capsule 2 may each be 0.8~1.2mm, preferably 1mm.
Soundproof principle：With reference to Fig. 2, sound wave is in the route of transmission by air, when encountering a homogeneous wall surface, makees in sound wave
Under, wall surface is vibrated by certain way, this part acoustic energy becomes transmission acoustic energy, in addition outside radiated noise, for most
For number wall surface, transmission acoustic energy is only one of hundreds of parts of incident acoustic energy or smaller, and most acoustic energy are reflected back toward
It goes, therefore, setting adequate shielding object can be so that most of sound energy reflection goes back, to reduce sonic propagation of making an uproar.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to the protection model of the present invention
It encloses.
