Abstract
The utility model provides an earplug filter core, which comprises a cylindrical chamber. The upper central part of the cylindrical chamber is provided with a sound outlet hole, while the lower central part of the cylindrical chamber is provided with a sound inlet hole. A woolen netted film is arranged above the sound inlet hole. A composite netted film is arranged above the woolen netted film. According to the technical scheme of the utility model, due to the adoption of the above reasonable physical structural design, based on the characteristics of the above mentioned materials, external noises can be effectively attenuated by the earplug filter core. The earplug filter core is wide in application range and strong in effect. Human voices can partially pass through the earplug filter core and the equalization of pressures inside and outside the ear is realized. The earplug filter core can be applied to emergencies and is comfortable to wear.
Description
Technical field
The utility model relates to the earplug field, refers to a kind of earplug filtering fuse especially.
Background technology
In industrial production, in machine room, the drilling well exploitation is medium, often produce the noise of various frequencies, if in such environment, work for a long time, can cause the decline of staff's hearing on the one hand, on the other hand, also may cause on other physiology of staff and psychological disorder, therefore, the personnel that work in such environment need wear the earplug with decrease of noise functions, and are also more about the earplug kind of noise reduction in the market, also relevant for the patent application of this class earplug, such as some fully closed earplugs, can be almost all sound in the external world be all completely cut off, reach the effect of protection hearing, but this class earplug is owing to completely cut off all voice signals, therefore, the personnel of wearing can't be linked up with personnel on every side, need take off earplug when needing to link up; On the other hand, this class earplug causes Er Nei and ear external pressure imbalance easily, thereby makes long periods of wear person produce phenomenons such as fatigue, dizziness, makes troubles to the user; And some have the earplug of selective filter, the decay sound wave of medium-high frequency section of the physical geometry of mainly using its filtering fuse, the SATT of bass frequency range is faint, and because the diversity of operational environment, when the user is exposed to the noisy environment that concentrates on the bass frequency range, can't play the effect of protection hearing; Also having in the market and use the DSP(Digital Signal Processing) chip handles the filtering fuse of sound, but well imagines that it is high a lot of that the cost of this series products is wanted.
The utility model content
The utility model proposes a kind of earplug filtering fuse, solved the problem that can't stir material pending in the resonant cavity in the prior art.
The technical solution of the utility model is achieved in that a kind of earplug filtering fuse, comprise: cylindrical chamber, described cylindrical chamber upper center is provided with sender, and the middle part, lower end is provided with sound inlet, described sound inlet top is provided with woollen goods nethike embrane, and described woollen goods nethike embrane top is provided with laminated film.
Further, described cylindrical chamber is the plastic cement cylindrical chamber.
Further, the diameter of described sound inlet is greater than the diameter of described sender.
Further, described laminated film is resin film.
Further, described resin film is PE film or PET film
By above-mentioned annexation, can reach good noise reduction, concrete implementation can be found out from said structure and annexation, described earplug filtering fuse on the whole an end for advancing the sound macropore, one end is for going out the sound aperture, because a little less than the acoustic wave diffraction ability of high band, so by this structure, can effectively reduce the sound wave of high band, secondly, adopt the plastic cement cylindrical chamber, has pliability preferably, and described woollen goods nethike embrane is because it is good porous sound wave absorbing material, when sound wave advance out-of-date, the medium-high frequency section that can significantly decay sound wave, and described laminated film, as the PE(polyethylene) film or PET(PETG) resin film such as film, sound wave had different transmission capacities, then can effective attenuation medium and low frequency section sound wave, simultaneously, we can be according to residing environment difference, frequency noise kind difference on every side can be adjusted a little to described earplug filtering fuse, such as adopts described woollen goods film and the described laminated film of different-thickness and material, come controlled filter injurious noise accurately, and because described earplug filtering fuse has the sound of going out aperture, rather than complete closed is so the user can hear extraneous voice etc. can make things convenient for emergency on the one hand the time, can make the equilibrium of ear external and internal pressure on the other hand, be not easy to produce sense tired out.
Therefore, the beneficial effects of the utility model are, by adopting physical geometry, the self-characteristic of while apply materials, reach the effective attenuation to noise under the various environment, and described earplug filtering fuse has the sound of going out aperture, can see through voice and balance ear external and internal pressure to a certain extent, can be used for emergent emergency case, and make long periods of wear more comfortable.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the planar structure schematic diagram of an embodiment of a kind of earplug filtering of the utility model fuse;
Fig. 2 is the generalized section of earplug filtering fuse shown in Figure 1.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, a kind of earplug filtering fuse comprises: cylindrical chamber 1, and cylindrical chamber 1 upper center is provided with sender 2, and the middle part, lower end is provided with sound inlet 3, and sound inlet 3 tops are provided with woollen goods nethike embrane 4, and woollen goods nethike embrane 4 tops are provided with laminated film 5.
Further, cylindrical chamber 1 is the plastic cement cylindrical chamber, certainly, also can adopt rubber, and other flexible glues such as silica gel are used as the material of cylindrical chamber.
Further, the diameter of sound inlet 3 is greater than the diameter of sender 2, and this design can be with the high frequency sound wave effective attenuation a little less than the diffracting power.
Further, laminated film 5 is resin film, and what adopt in the present embodiment is the PE film.
We will change earplug filtering fuse and place adaptive noise reduction earplug, and the sound wave of each frequency is effectively decayed to external world, simultaneously, because the reservation of sender 2, we can also hear part voice, for meeting an urgent need in emergency circumstances, and the equilibrium of ear external and internal pressure, comfortable wearing.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
