Description

Adjustable earplugs

The present invention relates to an earplug, and more particularly to an adjustable earplug that can adjust the shape of the earplug to conform to the shape or diameter of each ear canal.

There are many different types of earplugs on the market. Most of the earplugs are molded with soft fillers into the ear cans. The earplugs are gently pressed into the ear canal and are excellent in elasticity. Reverting to the original soft filling as soon as possible, so that the earplug can quickly close the outer ear canal without any gap, almost completely blocking the external environmental sound.

However, earplugs of this effect are not necessarily suitable for everyone. Some people wear the above-mentioned earplugs that can almost completely block the outside sound. Tinnitus may occur or the earplugs of the ears are tightly blocked around the external auditory canal, which changes the original comfortable environment in the ear and causes discomfort. Other earplugs often make the wearer feel uncomfortable when they need to wear them for a long time, so workers who wear the device under high noise are usually not worn or used only at the request of their employer. This is very inappropriate.

In view of this, the inventors feel that they have not perfected their efforts and painstakingly studied, and based on their accumulated experience in the industry for many years, and then provided a type of earplugs, in order to improve the lack of the above-mentioned conventional techniques.

One of the aims of this creation is to provide an adjustable earplug to provide a user The shape of the earplugs that have been inserted in the ear canal can be adjusted to meet the user's current purpose of using the earplugs, such as simply to completely block the noise or the comfort that needs to be worn for a long time, and the adjustment can be more consistent with each The difference in the individual ear canal environment.

In order to achieve the above objective, the earphone of the present invention comprises: an earplug body, which is plugged in the ear canal, the earplug body has an opening, and the earplug body extends inwardly from the opening to form an outer narrow inner portion. One of the widths of the accommodating space, and the earplug body has a blocking portion at one end of the opening; an adjusting column, one end of the adjusting column is provided with a plurality of elastic pieces, and the elastic pieces are arranged at an annular interval, and are arranged One end of the elastic piece is inserted into the accommodating space of the earplug body, and the surface of the column of the adjusting column is an inner circular curved surface; and a holding member is extended on the adjusting column One end, and the shape of the holding member is a ring to facilitate moving the adjusting column and thereby adjusting the shape of the earplug body.

The depth of the accommodating space of the earplug body is greater than the length of the adjusting column, and the material of the earplug body is a soft material. In addition, the earplug body is further provided with a hole to balance the internal and external pressure of the earplug body.

In this way, by the above means, the present invention can adjust the shape of the earplug body to conform to the shape of the ear canal, and if the discomfort is caused by too close fitting, it can also be relieved by adjusting the earplug body.

In the following description, the same components are denoted by the same reference numerals for the sake of understanding, in order to make the understanding of the present invention clear.

Please refer to FIG. 1 to FIG. 4 , which are exploded views, cross-sectional views and usage diagrams of different perspectives of the preferred embodiment of the present invention. As shown in FIG. 1 to FIG. 4, the adjustable earplug 1 of the present invention comprises: an earplug body 11 which is plugged in the ear canal, and the earplug body 11 has an opening 111, and the earplug body 11 The opening 111 extends inwardly to form an accommodating space 112 having an outer narrow inner width, and the earplug body 11 has a blocking portion 113 at one end of the opening 111, so that the earplug body 11 is not completely inserted due to excessive force. In the ear canal; an adjustment column 12, one end of the adjustment column 12 is provided with a plurality of elastic pieces 121, which are arranged at an annular interval, and are inserted into the earplug body with one end of the elastic piece 121 In the accommodating space 112 of the ellipse, the surface of the cylinder of the adjusting column 12 is an inner curved surface; and a holding member 13 is extended at the other end of the adjusting column 12, and the holding member The shape of 13 is a ring to facilitate moving the adjustment post 12 and thereby adjusting the shape of the earplug body 11. The adjusted earplug 1 of the present invention has the following effects.

First, when the earplug body 11 is inserted into the ear canal and the size is reduced, the surface of the earplug body 11 can be continuously contacted with the ear canal. The reason why the capability is such that the adjustment column 12 is inserted into the earplug body 11 during use, since the shape, size, and the like of each ear canal are different, the adjustment column 12 is required to be finely adjusted, and the earplug body is utilized. The surface of the accommodating space 112 of the 11 and the inner surface of the curved surface of the adjusting column 12 and the elastic sheets 121 are attached to each other. To change the shape of the earplug body 11, and since the depth d of the accommodating space 112 is greater than the length L of the adjusting column 12, the moving column 12 is moved from all directions, such as moving outward or moving inward. The shape of the original outer narrow inner width of the earplug body 11 can be changed to improve the user's discomfort or to better fit the earplug body 11 to the ear canal, and can also improve the general prior art to balance the earplugs. A disadvantage of the internal and external pressures is that a hole 114 is formed in the earplug body 11 so that the gas inside and outside the earplug body 11 can communicate with the hole 114 to balance the pressure inside and outside the earplug body 11.

Second, the surface of the earplug body 11 can conform to an irregular shape of the ear canal. Since the material of the earplug body 11 is a soft and slightly elastic material, the shape of the adjusting column 12 can be changed according to the movement of the adjusting column 12, and when it is taken out from the ear canal, the original shape before the original use is restored. .

In use, the user first grasps the holding member 13 on the adjusting column 12, such as by pulling the holding member 13 through the thumb and the index finger of the user, and inserting the holding member 13 into the earplug body 11, and then The earplug body 11 is placed close to the outer ear of the user, and then the user pushes the adjustable earplug 1 into the ear canal until the blocking portion 113 of the earplug body 11 is snap-fitted and comfortably fitted. In this way, the adjustable earplug 1 can be finely adjusted, such as to completely block the ear canal according to the user's needs to block the noise or have a certain comfort under long-term wearing, in particular, Finally, the position of the adjustable earplug 1 in the ear can be determined by the shape and size of the ear canal of each user. When it is not desired to use, the user only needs to withdraw the adjustment column 12 together with the earplug body 11 from the ear canal. Compared with the existing ear-in-ear earplugs, this creation has many advantages in use, especially in order to achieve the proper balance of fit, comfort and sound attenuation, and to enhance the user's long-wearing comfort. .

However, the above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, so it is common knowledge in the technical field or equivalent or easy to be familiar with the technology. The change and modification of the changer without departing from the spirit and scope of this creation shall be covered by the scope of the patent of this creation.
