Abstract
The utility model provides a novel cold -proof earmuff, including two protective sheaths, the protective sheath is used for the auricle of cover at people's ear, the inside acoustic through -hole that is equipped with of ear muff. The utility model discloses a protective sheath through setting up acoustic passageway intercommunication external auditory canal and external environment, makes external sound change in importing people's ear into in the parcel auricle. So both guaranteed the basic function of cold -proof auricle, enabled again to guarantee that user's sense of hearing was unrestricted. Overall structure is simple, and easily make and produce, and low in production cost, easily popularize.
Description
Technical field
The utility model relates to a kind of protective sleeve, particularly relates to a kind of Novel heat-preservation ear muff.
Background technology
Current warm earmuffs (warm, the ear muff of ear, warm ear, an earmuff) pair is connected together for cold-proof screening ear thing by the metal tape of strap, elastic cord or softness.The structure of protective sleeve is very simple, primarily of support and protective sleeve composition.Protective sleeve, from quality, divides fox hair ear muff, rabbit hair ear muff, velveteen ear muff, staple fibre ear muff etc.From effect, be basic function with warming, then on this basis, also can attach the functions such as earphone.In structure, can be used alone, or use with cap, mouth mask one.But, due to the covering that protective sleeve is thick to external auditory meatus, to a certain degree have impact on the auditory function of ear, to exchange with external environment to wearer and bring discomfort; Secondly, due to warm earmuffs usually outdoor use in the winter time, on such as road, sports ground, skifield etc., reduce wearer to the vigilance of around hazards and dodging ability, thus threaten the personal safety of wearer.
The major technique defect of existing warm earmuffs: warm earmuffs reduces auricle and collects extraneous sound wave, and imports the ability of eardrum into through external auditory meatus; Certain degree weakens the volume (loudness) importing sound into; Completely cut off the medium of sound air transmitted.These problems directly cause not to be heard, does not hear or auditory localization obstacle.
Utility model content
The technical problems to be solved in the utility model, is to provide a kind of Novel heat-preservation ear muff, comprises two protective sleeves, and described protective sleeve is for covering on the auricle of people's ear, and described earmuff inside is provided with acoustic through hole.
Further, described acoustic through hole entirety is in horn-like, and its aperture near people's ear side is less than the aperture of opposite side.
Further, be provided with voice conducting pipe in described acoustic through hole, described voice conducting pipe entirety is in horn-like, and its aperture near people's ear side is less than the aperture of opposite side.
Further, one end of described voice conducting pipe larger aperture is provided with draw-in groove, and described protective sleeve is inner to being provided with projection by draw-in groove.
Further, described acoustic through hole is provided with protector away from the side of people's ear, and described protector is provided with more than one through hole.
Further, the overall rounded structure of described protector.
Protective sleeve of the present utility model, while parcel auricle, being communicated with external auditory meatus and external environment by arranging sound-delivery channel, making extraneous sound be easier to import people's ear into.So both ensure that the basic function of warming auricle, the guarantee user sense of hearing can be made again unrestricted.Overall structure is simple, is easy to manufacture and produce, and production cost is low, is easy to universal.
Accompanying drawing explanation
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments:
Fig. 1 is the overall structure schematic diagram of Novel heat-preservation ear muff of the present utility model;
Fig. 2 is the internal structure schematic diagram of earmuff of the present utility model;
Fig. 3 is the structural representation of voice conducting pipe of the present utility model;
Fig. 4 is the structural representation of protector of the present utility model.
Detailed description of the invention
Refer to Fig. 1 to 4, be a kind of Novel heat-preservation ear muff as most preferred embodiment of the present utility model, comprise two protective sleeves 10 and support 20, support 20 two ends respectively connect a protective sleeve 10.This protective sleeve 10 is for covering on the auricle of people's ear, and this protective sleeve 10 inside is provided with acoustic through hole 112.This acoustic through hole 112 entirety is in horn-like, and its aperture near people's ear side is less than the aperture of opposite side.
In this acoustic through hole 112, arrange voice conducting pipe 12, this voice conducting pipe 12 entirety is in horn-like, and its aperture near people's ear side is less than the aperture of opposite side.The monnolithic case of this voice conducting pipe 12 and the shape of acoustic through hole 112 suitable, can firmly be arranged in acoustic through hole 112.One end of this voice conducting pipe 12 larger aperture is provided with draw-in groove, and this protective sleeve 10 inside is to being provided with projection 111 by draw-in groove 121.This draw-in groove 121 is stuck on projection 111 with being fixed in protective sleeve 10 of making voice conducting pipe 12 firm.
Be provided with protector 13 at this acoustic through hole 112 away from the side of people's ear, for the dust storm etc. of isolated outside, avoid the open air of external auditory meatus especially at severe cold weather in external environment condition.This protector 13 is provided with more than one through hole, and these through holes facilitate sound to pass through, and also this protector 13 can be arranged to the structure with holes such as latticed.Preferably this protector 13 is designed to circular configuration, with adaptive acoustic through hole.Also other shapes can be designed to, as rectangle, triangle, the shape such as trapezoidal.
In sum, protective sleeve of the present utility model, while parcel auricle, being communicated with external auditory meatus and external environment by arranging sound-delivery channel, making extraneous sound be easier to import people's ear into.So both ensure that the basic function of warming auricle, the guarantee user sense of hearing can be made again unrestricted.Overall structure is simple, is easy to manufacture and produce, and production cost is low, is easy to universal.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
