Abstract
The present invention discloses a pair of hearing-aid ear-plugs. The ear-plugs comprise ear-plug main bodies (1) and sound channels (3). The ear-plug main bodies (1) consist of support sheets (2). Air channels (4) are arranged between the ear-plug main bodies (1) and the sound channels (3). The air channels (4) are non-linear circuitous type air channels arranged along the long direction of ear canals. The ear-plug structure effectively avoids sound pressure leakage and avoids eardrum damage due to excessive stuffing. Sound pressure leakage or absorption is reduced by the surface design of the ear-plugs to the utmost extent. The design of the circuitous type air channels (4) eliminates blocking effect, reduces excessive leakage of horn sound waves or sound pressure, and prevents excessive sound waves outside ears from entering inner ears. Besides, the present invention can avoid loosening or displacement and avoid receiver vibration and resonance. The ear-plugs are soft, comfortable to wear, convenient to exchange or clean, and easy to put and take out.
Description
Technical field
The present invention relates to a kind of earplug of hearing aids, belong to the hearing aids technical field.
Background technology
In the hearing aids technical field, button commonly used is generally to have definite shape, is made by silicon rubber.A part of earplug in European Union (EU) appearance design of on April 1st, for example known registration 000007893-0001 number.Such earplug in use often runs into following situation: owing to the different acoustic pressures that cause with size and shape of length of user's duct are revealed; Use causes near the black-out effect that can not circulate of the air the duct center; Material is crossed soft meeting and is caused becoming flexible or coming off, and material is really up to the mark can damage duct or the like.Prevent along the acoustic pressure of earplug periphery reveal, prevent near near the black-out effect of the circulation of air duct center, prevent the loosening of earplug or come off, prevent vibrations and resonance and be easy to wear and take out, be that those skilled in the art want the technical problem that solves always.
Publication number is the earplug that 101138273 Chinese invention patent application discloses a kind of hearing aids, it has solved the acoustic pressure leakage effectively, ventilating opening is set solves the black-out effect problem, but, such structure De Ersai does not but solve loudspeaker sound wave or sound pressure and leaks in a large number, and the problem that sound wave enters inner ear in a large number outside the ear.
Summary of the invention
The present invention will solve the problems of the technologies described above exactly, and providing a kind of can prevent on the basis of black-out effect preventing the leakage of earplug periphery acoustic pressure, can reduce loudspeaker sound wave or sound pressure and leak, and reduces the earplug that the outer sound wave of ear enters inner ear.
For achieving the above object, technical scheme of the present invention is: a kind of button, comprise the sound channel on earplug bodies and the earplug bodies, described earplug bodies is made of support chip, described support chip is the mushroom-shaped shape, be provided with air flue between described earplug bodies and sound channel, described air flue is nonlinear circuitous type along the duct length direction.
The front end of described support chip is ganoid concave surface; The rear end of described support chip is shaggy convex surface.
Described support chip is for to be made of the flabellum shape blade.
Described earplug bodies is made of a slice, two or three support chips.
For preventing black-out effect effectively, the aperture of described air flue is greater than 0.5mm.
Described earplug bodies upwards is circle, ellipse or polygon in the footpath of duct.
For the pressure and the sound intensity of keeping sound wave prevents to leak, the contact area of described earplug bodies and duct is not less than 0.5mm
2,, along the contact length of duct length direction at 0.1mm ~ 5mm.
Described earplug material is hardness single below 35 or mixes high molecular polymer that the polymer of described earplug material is generally silicon rubber, polyurethane, chlorine tincture rubber or plastics.
Earplug structure of the present invention, when a slice support chip of earplug bodies was squeezed distortion, other support chips also can keep its shape, can prevent effectively that so just earplug is subjected to duct pressure and produces unstability or torsional deformation, to guarantee that earplug closely contacts with duct, do not produce the circumference acoustic pressure and leak; The surface design of earplug support chip reduces sound wave to greatest extent and leaks or " being absorbed ", and acoustic reflection is returned internal auditory meatus or ear-drum; In addition, the present invention can prevent the loosening or dislocation of receiver, prevent vibrations and resonance, and is soft and wear comfortablely, is convenient to change or cleaning, is easy to put and take out.The design of circuitous type air flue when solving the black-out effect problem, reduces the loudspeaker sound wave or sound pressure is excessive leaks, and reduces the outer excessive problem that enters inner ear of sound wave of ear.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a structure cutaway view of the present invention.
Fig. 3 is three utmost point monolithic earplug structural representations.
Fig. 4 is the three lug plug structure schematic diagrames in three holes for sound channel.

Embodiment
As shown in Figure 1, a kind of button comprises the sound channel 3 on earplug bodies 1 and the earplug bodies 1, and described earplug bodies 1 is made of support chip 2, and described support chip 2 is the mushroom-shaped shape; As shown in Figure 2, be provided with air flue 4 between described earplug bodies 1 and sound channel 3, described air flue 4 is nonlinear circuitous type along the duct length direction.
For with sound wave focusing reflected back ear-drum, the front end of support chip 2 is ganoid convex surface, and sound wave just can not dispersed by diffraction like this.Surface treatment can be carried out in the surface of support chip 2, such as coating, plated film etc., ETFE, PTFE, Parylene, Parylin,, Parylast,, mode such as Polyurethane, Polyethylenimin, Polyimide.
For outer wave absorption of ear or diffraction are dispersed, the rear end of support chip 2 is shaggy concave surface, and the sound wave of external auditory meatus will can not enter internal auditory meatus like this.
Described support chip 2 is for to be made of flabellum shape blade 5, and the blade 5 that constitutes support chip 2 can be monolithic, biplate or multi-disc.
Described earplug bodies 1 is made of a slice, two or three or multi-disc support chip 2.
The sheet number of support chip 2 is called number of poles, and the blade sheet number of support chip 2 is called the sheet number, and then earplug just can be divided into one pole monolithic, one pole multi-disc, types such as multipole monolithic, multipole multi-disc.Shown in Figure 3 is three utmost point monolithic earplug structural representations, and it has 3 support chips 2, and every support chip 2 is made of a slice blade 5.
Shown in Figure 4 is that sound channel is the three lug plug structure schematic diagrames in three holes.
In order to prevent black-out effect effectively, the aperture of described air flue 4 is greater than 0.5mm, and to prevent black-out effect, air flue 4 should be circuitous type rather than linear pattern along the duct length direction for circulation of air, reduce loudspeaker sound wave or sound pressure and leak, reduce the outer sound wave of ear and enter inner ear.Fig. 5 is the cutaway view of Fig. 4, can see also that from figure gas off-take 4 should be circuitous type rather than linear pattern along the duct length direction.
Described earplug material is hardness single below 35 or mixes high molecular polymer that the polymer of described earplug material is generally silicon rubber, polyurethane, chlorine tincture rubber or plastics.
The foregoing description does not limit the present invention in any way, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
