Abstract
The utility model provides a cerumen prevention device with an acoustic damping effect, comprising an acoustic damping net and a cerumen protective device body, wherein the cerumen prevention device body is a hollow cylinder, the bottom portion of the cerumen prevention device body is provided with a slot, inside the slot there is provided with a replaceable acoustic damping net, at the periphery of the cylinder located above the slot there is provided a barb structure, the top portion of the cylinder is also provided with a crimping extending outwards, the slot is arranged at a 1/3 position away from the bottom portion of the cylinder, the acoustic damping net is prepared by a filter net prepared by a PE material, and the surface of the filter net is coated with a layer of nanometer waterproof paint. The cerumen prevention device with an acoustic damping effect not only can effectively prevent cerumen from entering a hearing aid, but also can play a role of acoustic damping.
Description
Technical field
The utility model 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, often can running into earwaxes stops up the receiver outlet sound mouth, causes hearing aids without the problem that amplification sound or amplification sound die down, and uses 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 characteristic frequency in the sound in the hearing aids, reaches reduction sound output size, changes the frequency response of the whole output of hearing aids.Existing sound damper such as the patent No. are in 96105590.1 the Chinese patent literature, a kind of loudspeaking damper for the sound output device is provided, and it represents excellent shape retention properties during molding, 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 this cloth of molding under the heating pressurized conditions with mylar.Other has the patent No. is in 99808847.1 the Chinese patent literature, disclosed another kind of acoustic damping material, 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 described side are mutually faced and formed sandwich construction, and elastic plate can be made by any elastomeric polymer film, for example polyolefin, especially polyethylene.
Traditional earwax protector and sound damper all need to use separately respectively, and since the difference of various hearing aids type outward appearances can't support the 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.
The utility model content
The technical problems to be solved in the utility model, be to provide a kind of can effectively prevent from earwaxing enter hearing aids, can play again the protector of earwaxing of the effect of acoustic damping.
The technical problems to be solved in the utility model is achieved in that a kind of protector of earwaxing with the acoustic damping effect, comprise the acoustic damping net and the protector of earwaxing, it is characterized in that: the described protector of earwaxing is the cylinder of hollow, its bottom is provided with a slot, 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.
Described slot is arranged on cylinder from approximately 1/3rd the position of bottom.
Described acoustic damping net uses PE material filter screen to make surface spraying one deck nano water-proof coating of filter screen.
Compared with prior art, the utlity model has following advantage:
1. preventing that ear from earwaxing enters hearing aids receiver outlet sound mouth, stops up or damage the hearing aids receiver;
2. output has damping action to hearing aids, can change by purpose the frequency response of the whole output of hearing aids;
3. adopt the interchangeable protection filter screen of earwaxing, can reduce loss with old money product ratio.
Description of drawings
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is that the utility model is with the overall structure schematic diagram of the protector of earwaxing of acoustic damping effect.
Fig. 2 is that the utility model is with the sectional view of the protector of earwaxing of acoustic damping effect.
Fig. 3 is that the utility model is with the end view of the protector of earwaxing of acoustic damping effect.
Fig. 4 is that the utility model is with the structural representation of the acoustic damping net of the protector of earwaxing of acoustic damping effect.
Embodiment
See also Fig. 1 to Fig. 4, that the utility model is with the structural representation of the protector of earwaxing of acoustic damping effect, the described protector of earwaxing with the acoustic damping effect, comprise acoustic damping net 1 and the protector 2 of earwaxing, the described protector 2 of earwaxing is the cylinder of hollow, its bottom is provided with a slot 21, interchangeable acoustic damping net 1 is installed in the slot 21, 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 described slot 21 is arranged on the cylinder approximately 1/3rd the position from the bottom; Described acoustic damping net 1 uses PE material filter screen to make surface spraying one deck nano water-proof coating of filter screen.
Use the protector of earwaxing described in the utility model, can prevent from that ear from earwaxing to enter hearing aids receiver outlet sound mouth, stop up or damage the hearing aids receiver; And because described acoustic damping net uses PE material filter screen to make, surface spraying one deck nano water-proof coating of filter screen, output has damping action to hearing aids, can change by purpose the frequency response of the whole output of hearing aids; And adopt the interchangeable protection filter screen of earwaxing, can greatly reduce loss with the old money product ratio of needs.
