Description

In view of the above problems, the present invention uses the earplugs for high frequency sound countermeasures, low frequency sound / medium frequency sound countermeasures, and low frequency sound / medium frequency sound / high frequency sound countermeasures having a sound absorbing function. It is an object of the present invention to provide three types of sound-absorbing transmission-type earplugs that do not require any medication or application, and that can reproduce and listen to natural soft sounds.

In order to solve the above-mentioned problem, the sound-absorbing transmitted-tone earplug according to claim 1 is a fine-sponge with good skin and a little tension so that the outer ear hole of a person's ear is not burdened. in order to have a little formed into the shape of the larger similarity than the ear hole, which was the ear hole sponge, the ear hole sponge is inserted and held in the cartilage of the ear hole, the hole opened to the outside of the ear hole and a portion pinna lead regarded as an ear hole end, shaping the end face facing the outside of the ear hole sponge and its end so as to be a shape of the same surface, also in contact with this surface, ear hole end In order to avoid interference with the part where the auricle is connected to the end of the ear canal, excellent rubber plate wear resistance by forming a sound absorbing plate a as a countermeasure, the the said sound absorbing plate a A material obtained by partial and combined adhesive in contact with the end face of the same shape and surface facing the outside of the ear hole sponge and earplugs, the earplugs of the sound by plugging a hole in which the sound absorbing plate A is opened to the outside of the ear It is characterized by being configured to prevent diffraction.

Absorbing type transmission sound type earplug of claim 2, wherein instead of the sound absorbing plate A in absorbing type transmission sound type earplug of claim 1, since the sound absorption is also influenced by the frequency band, low-frequency sound, the rubber plate elastic excellent as a measure medium frequency sound produced in the same manner as the sound absorbing plate a sound-absorbing plate B, the a pre-Symbol acoustical panel B ear hole sponge molding and bonding in claim 1 and the same methods An earplug is used as the earplug, and the earplug is configured such that the sound absorbing plate B can prevent sound diffraction by closing a hole opened outside the ear.

Absorbing type transmission sound type earplug of claim 3 is the external auditory pore sponge and the sound absorbing plate A · said sound absorbing plate B in the sound absorption type transmission sound type earplug of claim 1 and claim 2, firstly the the sound absorbing plate a and the sound absorbing plate B was bonded together in the same shape and surface, this as a sound absorbing plate C measures the low frequency sound, medium frequency sound-high frequency sound, face and this was the sound absorbing plate B side The end plug facing the outside of the outer ear hole sponge is bonded in the same shape and surface to make an ear plug, and the ear plug has a sound by closing the hole opened by the sound absorbing plate C to the outside of the ear. It is characterized in that it can be prevented from diffraction.

Further, the earplugs because blocking the ear acoustical panel A, the moisture such as sweat loving in the ear ear hole sponge can be absorbed.

This eliminates the noise that can be heard roughly so that the sound source cannot be identified, thus eliminating the inflammation and tingling pain that occurred in the ear canal. It becomes useless.

1 through 7, the earplug 1 for the high frequency sound measures, and a sound absorbing plate A3 excellent rubber plate in the ear hole sponge 2 and wear resistance, adhesion constructed in accordance with FIGS. 2 and 5 To do.

The earplug 1 includes an outer ear hole sponge 2 and a rubber plate sound absorbing plate B4 excellent in elasticity, and is bonded and configured in accordance with FIGS. 3 and 6 as a countermeasure against low frequency sound and medium frequency sound.

Further, the earplug 1 is a measure low-frequency sound, medium frequency sound-high frequency sound, provided with a ear hole sponge 2 and the sound absorbing plate A3 and the sound absorbing plate B4, constituting adhere according to FIGS. 4 and 7 .

Claims (3)

A fine, fine-grained sponge is applied to the outer ear canal so that it does not place a burden on the ear canal, and is shaped into a similar shape slightly larger than the outer ear canal. and sponge, the ear hole sponge is inserted and held in the cartilage of the ear hole, it considers the outside open hole and pinna leads part of the ear hole and ear hole end, the ear hole sponge and its end the end face facing the outside, molded so as to be a shape of the same surface, also in contact with this surface, with the shape of the same surface of the ear hole ends, and in order to located outside the ear hole edge the thing which has a cutout portion for avoiding interference with the portion auricle leads ear hole end, excellent rubber plate wear resistance by forming a sound absorbing plate a as a high-frequency sound countermeasure, the said sound-absorbing a portion in contact with the plate a with the end face of the same shape and surface facing the outside of the ear hole sponge And adhere to the ones earplugs, the earplugs sound absorption type transmitted sound, characterized by being configured to capable of preventing diffraction of sound by plugging a hole in which the sound absorbing plate A is opened to the outside of the ear Ear plug. Instead of the sound absorbing plate A in absorbing type transmission sound type earplug of claim 1, since the sound absorption is affected by the frequency band, the sound absorbing plate rubber plate having elasticity superior as a countermeasure low-frequency sound, medium frequency sound prepared in the same manner as the sound absorbing plate a as B, the ear hole sponge and the sound absorbing plate B is the earplugs what molded-bonded in the same manner as according to claim 1, wherein the earplugs the sound absorbing plate B A sound-absorbing transmission-type earplug, characterized in that the sound can be prevented from being diffracted by closing a hole opened outside the ear. The ear hole sponge and the sound absorbing plate A-said sound absorbing plate B in the sound absorbing type transmission sound type earplug of claim 1 and claim 2, firstly the sound absorbing plate B and the sound absorbing plate A in the same shape and surface bonded together, this as a sound absorbing plate C measures the low frequency sound, medium frequency sound-high frequency sound, which outside the same shape and the end face facing the ear hole sponge was surface and said sound absorbing plate B A sound absorbing type characterized in that the earplug is configured to prevent sound diffraction by closing a hole opened to the outside of the ear. Transmitted earplugs.
