Thecore member 1 is formed as a part of ahearing aid 12. - It is required that the ear plug is superior in prevention of noise of high frequency when inserted into the external auditory canal. However, if the degree of prevention of noise is improved at that time, there occurs a pressure difference between the external atmosphere and an inside of the external auditory canal, accompanied by problems such as feeling of oppression with clogging of the ear. The pressure difference can be avoided by manufacturing the[0004]
core member 1 in a straight form, however, sound generated from thehearing aid 12 having an external portion la of thecore member 1 is easy to leak outward due to the short length of the vent in thecore member 1. This causes so-called howling to remarkably decrease the performance of the ear plug. - Consequently, an object of the present invention is to lengthen a communicating passage or vent to an effective degree for remarkably decreasing the pressure difference between the inside of the external auditory canal and the external atmosphere as well as preventing leakage of sound causing so-called howling.[0005]
- In order to realize this object, the present invention provides an ear plug to be interted into the external auditory canal, having a compressible sleeve member and a core member attached therein, the improvement in which plural projections or a single projection are formed intermittently or continuously on an exterior of the core member, and vent is formed through or along the projection to make the external auditory canal communicate with the external atmosphere when inserted into the external auditory canal.[0006]
- According to the present invention, the projections are formed on the exterior of the core member and the vent is defined through or along the projection to make the external auditory canal communicate with the external atmosphere, so as to lengthen a communicating passage or vent to an effective degree for remarkably decreasing only the pressure difference between an inside of the external auditory canal and the external atmosphere as well as preventing leakage of sound causing so-called howling.[0007]
- In the present invention, it is preferable that an innermost vent is formed through an innermost projection of the intermittently formed projections or through an inner end portion of the core member to open into the external auditory canal, other vents are formed through other respective projections, and an outermost vent is formed through an outer end portion of the core member to open into the external atmosphere.[0008]
- In this case, the vents are preferably formed at different positions of adjacent projections, and each of the projections can be ring-shaped.[0009]
- It is also preferable that a continuous vent or groove is formed along the continuously formed projection to make an outermost vent communicate with the external auditory canal, and an outermost vent is formed through an outer end portion of the core member to open into the external atmosphere.[0010]
- In this case, an additional vent is preferably formed through an inner end potion of the core member, and the continuously formed projection can be spiral-shaped.[0011]
- It is further preferable that the sleeve member is composed of a sponge like material such as polyurethane and the core member is composed of a flexible material such as polyethylene, so as to be deformed to meet the shape of the external auditory canal, and that a penetrating lumen is formed through an inside of the core member from one end to another end.[0012]
- A hearing aid can has the core member in one body.[0013]

ear plug 15 of the present invention comprising acore member 1 composed of a flexible material such as polyethylene having a penetratinglumen 14 formed inside from one end to another end, plural disc-like or ring-shaped projections 5 formed intermittently on an exterior of thecore member 1, and acompressible sleeve member 2 composed of a sponge-like material such as polyurethane. Thesleeve member 2 is attached to thecore member 1 through an adhesive agent (not shown) adhered particularly between the circumference of theprojections 5 and thesleeve member 2 so as to maintain respective spaces betweenadjacent projections 5. - The[0035]
projections 5 havevents innermost vent 6ais formed through aninnermost projection 5aof the projections5 (or another vent4 (see FIG. 5 ) can be formed instead through an inner end portion of the core member1) to open into the external auditory canal,other vents 5 are formed through otherrespective projection 5, and anoutermost vent 3 is formed as a penetrating hole through an enlarged outer end portion1aof thecore member 1 to open into the external atmosphere. Thevents adjacent projections 5 and thevent 7 at the left end communicates with theoutermost vent 3. - When the[0036]
ear plug 15 with ahearing aid 12 in one body is inserted into the external auditory canal13 as shown in FIG. 4, thesleeve member 2 composed of a sponge-like material is elastically compressed by an inner wall surface of the external auditory canal13 while thecore member 1 is flexibly deformed so as to meet the shape of the external auditory canal13. - According to this construction of the[0037]
ear plug 15, theprojections 5 are formed on the exterior of thecore member 1 as well as thevents projections 5 to make the external auditory canal13 communicate with the external atmosphere, so as to lengthen a communicating passage or vent to an effective degree for remarkably decreasing only the pressure difference between an inside of the external auditory canal13 and the external atmosphere as well as preventing leakage of sound causing so-called howling. - The positions of the[0038]
vents portions respective projections 5, particularly at an angular interval of 180° according to a second embodiment of the present invention as shown in FIGS. 5 and 6. Theoutermost vent 3 can be easily formed when it is groove-shaped instead of the penetrating hole of FIG. 2. - FIG. 7 shows a third embodiment of a core member of an ear plug wherein a continuous vent or[0039]
groove 11 is formed along a continuously formed spiral-shaped projection 10 like a single projection to make theoutermost vent 3 communicate with the external auditory canal. - Also in this construction of the ear plug of FIG. 7 having the[0040]
core member 21 with the spiral-shaped projection 10 and thesleeve member 2 as already shown in FIG. 2, thecontinuous vent 11 extending along theprojection 10 serves to make the external auditory canal13 communicate with the external atmosphere so as to lengthen a communicating passage or vent to an effective degree for remarkably decreasing only the pressure difference between the inside of the external auditory canal13 and the external atmosphere as well as preventing leakage of sound causing so-called howling. Besides, the spiral-shaped projection 10 can be easily formed on thecore member 21 like an external thread. - FIG. 8 shows a[0041]
further embodiment 25 of an ear plug with ahearing aid 12 having thesleeve member 2 attached to thecore member 21 as shown in FIG. 7. - The above-described[0042]
