Abstract
The utility model relates to a novel noise-proof earplug which is composed of an earplug body and a noise damping column. The earplug body is in nipple shape. The ear damping column which is composed of a column core and a column wall is arranged in the center of the ear plug body. The earplug body is made of soft elastic materials which have an excellent sound absorption function. The utility model has the advantages of excellent effect in sound insulation, comfortable adornment and convenient operation. The utility model is especially suitable for preventing industrial noise, such as the noise in a textile mill workshop or in an aircraft cabin, etc.
Description
This utility model relates to a kind of people's ear protection device of putting in ear, relates in particular to a kind of ear plug.
Commercially available ear plug is a cone-shaped earplug, is made by materials such as flexible plastic or foam plasticss.Though this earplug has certain its anti-noise function, after wearing for a long time, in ear is swollen, and causes dizziness, feels sick, and easily come off or lose.This earplug its anti-noise effect is also relatively poor, can not satisfy the actual needs of protection people's ear and anti-industrial noise and life noise.Chinese patent CN92215956.4 discloses a kind of ear plug, and it is by three floor damping fin, two floor sonic disintegration districts, earplug cylinder and help parts such as wearing sleeve pipe to form, complex structure, and erasure effect is undesirable.
The purpose of this utility model is to provide that a kind of soundproof effect is good, simple in structure, comfortable wearing, ear plug easy to use.
Ear plug of the present utility model, comprise the earplug body, be characterized in that the earplug body is " nipple " shape, is provided with noise damping post in the earplug body, noise damping post is contained in the central authorities of earplug body, and make by resilient material by the softness with good sound absorption function for the earplug body.Noise damping post is made of post core and post jamb.
Ear plug of the present utility model has following advantage: have good its anti-noise effect 1..Compare with commercially available earplug, its sound insulation value is greatly improved, and its reason is that it has specific shape, employed material with good performance muffler, with and the particular structure feature.This earplug is specially adapted to anti-industrial noise, the noise in for example noise in the textile mills, or aircraft cabin etc.2. simple in structure, be convenient to make, cost is low.3. because the earplug body coincide with external auditory meatus, and employing softness and resilient material cause and wear the people and feel comfortably cool handy when using.
This utility model has following accompanying drawing:
Fig. 1: the structural representation of novel ear plug.
Fig. 2: noise damping post sketch map.
Below in conjunction with drawings and Examples this utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.Among the figure, 1 is the earplug body, and 2 is noise damping post.The profile of earplug body 1 is " nipple " shape, and this shape helps to make earplug body 1 and external auditory meatus and auricle well to coincide, and improves sound damping effect.The height of earplug body 1 is about the 20-26 millimeter, and maximum gauge is about the 16-23 millimeter.Earplug body 1 is made by materials such as flexible plastic with good sound absorption function or rubber.Noise damping post 2 is located at the central authorities of earplug body 1.As shown in Figure 2, noise damping post 2 is made up of post core 3 and post jamb 4.Post core 3 is made by the velvet-like sponge of good muffling effect, and post jamb 4 is made by the compo with certain intensity.Noise damping stem stem 2 had both had good sound deadening, played certain supporting role again.By can pushing external auditory meatus to the earplug body easily, and make whole earplug show consideration for tight external auditory meatus, to promote sound damping effect with hand propelled noise damping post 2.The diameter of noise damping post 2 is 3 millimeters (also can be designed to the 2-4 millimeter), and length is 14 millimeters (can be designed to the 13-18 millimeter).
Earplug body 1 is fixedlyed connected with earplug line (not drawing among the figure), and an earplug line fuses two earplug bodies 1.Like this, earplug is more convenient for carrying and is difficult for losing.
