Abstract
The invention provides an earwax protector with a sound-damping function. The earwax protector comprises a sound-damping screen and an earwax protector body which is a hollow cylinder, the replaceable sound-damping screen is mounted in a slot which is arranged at the bottom of the cylinder, barb structures are further arranged on the periphery of the cylinder above the slot, turned edges extending outwards are further arranged at the top of the cylinder, the slot is arranged at the position, about one third distance away from the bottom, of the cylinder, the sound-damping screen is made of a PE (poly ethylene) filter screen, and a nano waterproof coating layer is sprayed on the surface of the filter screen. The earwax protector with the sound-damping function is capable of effectively preventing earwax from entering a hearing aid and damping sound.
Description
Technical field
The present invention relates to a kind of medicine equipment, particularly a kind of protector of earwaxing of hearing aids.
Background technology
Earwaxing is people's ear normal secretion, appears in people's external auditory meatus, generally is light yellow viscous liquid, runs into after the air drying to solidify.For the hearing aids user, run into to earwax through regular meeting and stop up the receiver outlet sound mouth, cause hearing aids not have the problem that amplification sound or amplification sound die down, use the protector of earwaxing can effectively avoid the problems referred to above.
The effect of sound damper mainly is the energy that consumes a certain CF in the sound in the hearing aids, reaches reduction sound output size, changes the frequency response of the whole output of hearing aids.The existing sound damper such as the patent No. are in 96105590.1 the Chinese patent document; A kind of loudspeaking damper that is used for output device is provided, and it represents excellent shape retention properties during moulding, to the operational environment high safety; Have excellent water proofing property, thermal endurance and durability.The preparation method of loudspeaking damper is, the cloth that the mixed yarn of Wholly aromatic polyamide fiber and aromatic polyester fiber is formed floods with mylar, at this cloth of heating and pressurizing condition molded.Other has the patent No. is in 99808847.1 the Chinese patent document, to have disclosed another kind of acoustic damping material, and it comprises at least one elastic plate; Wherein, Every block of plate has one first side and one second side, and at least two parts of said side are faced each other and formed sandwich construction, and elastic plate can be processed by any elastomeric polymer film; For example polyolefin, especially polyethylene.
Traditional earwax protector and sound damper all need be distinguished independent use, and since the difference of various hearing aids type outward appearances, supporting use simultaneously; And the protector of earwaxing that adopts on the existing part hearing aids is the integral type design, after the obstruction of earwaxing, just integral body is abandoned, and causes great waste.
Summary of the invention
The technical problem that the present invention will solve is to provide a kind of entering hearing aids that can effectively prevent to earwax, and can play the protector of earwaxing of the effect of acoustic damping again.
The technical problem that the present invention will solve is achieved in that a kind of protector of earwaxing that has the acoustic damping effect; Comprise the acoustic damping net and earwax protector; It is characterized in that: the said protector of earwaxing is the cylinder of hollow, and its bottom is provided with a slot, and interchangeable acoustic damping net is installed in the slot; The cylindrical periphery that is positioned at the slot top also is provided with overhead structure, and cylindrical top also is provided with outward extending crimping.
Said slot is arranged on about 1/3rd the position of cylinder from the bottom.
Said acoustic damping net uses PE material filter screen to process, surface spraying one deck nano water-proof coating of filter screen.
Compared with prior art, the present invention has following advantage:
1. preventing that ear from earwaxing gets into hearing aids receiver outlet sound mouth, stops up or damage the hearing aids receiver;
2. output has damping action to hearing aids, can change the frequency response of the whole output of hearing aids by purpose;
3. adopt the interchangeable protection filter screen of earwaxing, can reduce loss with old money product ratio.
Description of drawings
Combine embodiment that the present invention is further described with reference to the accompanying drawings.
Fig. 1 is the overall structure sketch map that the present invention has the protector of earwaxing of acoustic damping effect.
Fig. 2 is the sectional view that the present invention has the protector of earwaxing of acoustic damping effect.
Fig. 3 is the end view that the present invention has the protector of earwaxing of acoustic damping effect.
Fig. 4 is the structural representation of the acoustic damping net of the present invention's protector of earwaxing of having the acoustic damping effect.
Embodiment
See also Fig. 1 to Fig. 4; Be the structural representation that the present invention has the protector of earwaxing of acoustic damping effect, the said protector of earwaxing that has the acoustic damping effect comprises acoustic damping net 1 and earwaxes protector 2; The said protector 2 of earwaxing is the cylinder of hollow; Its bottom is provided with a slot 21, and interchangeable acoustic damping net 1 is installed in the slot 21, and the periphery that is positioned at slot 21 tops on the cylinder also is provided with overhead structure 22; Cylindrical top also is provided with outward extending crimping 23, and said slot 21 is arranged on the cylinder about 1/3rd position from the bottom; Said acoustic damping net 1 uses PE material filter screen to process, surface spraying one deck nano water-proof coating of filter screen.
Use the protector of earwaxing of the present invention, can prevent that ear from earwaxing to get into hearing aids receiver outlet sound mouth, stop up or damage the hearing aids receiver; And because said acoustic damping net uses PE material filter screen to process, surface spraying one deck nano water-proof coating of filter screen, output has damping action to hearing aids, can change the frequency response of the whole output of hearing aids by purpose; And adopt the interchangeable protection filter screen of earwaxing, can significantly reduce loss with the old money product ratio of needs.
Claims (3)
1. protector of earwaxing that has the acoustic damping effect; It is characterized in that: comprise the acoustic damping net and earwax protector; The said protector of earwaxing is the cylinder of hollow, and its bottom is provided with a slot, and interchangeable acoustic damping net is installed in the slot; The cylindrical periphery that is positioned at the slot top also is provided with overhead structure, and cylindrical top also is provided with outward extending crimping.
