Referring to FIGS. 3 to 6 , the ear tip 100 according to the present invention is provided in the earphone head 200 and can maintain airtightness while inserted into the ear hole. To this end, the ear tip 100 may include a fixing part 110 inserted into and fixed to the earphone head 200 . The ear tip 100 is also provided in the form of a propeller that expands in the output direction from the fixing part 110, and is folded while being rolled in the direction of the fixing part 110 when fitted into the ear hole. Elastic wearing part that expands and contracts according to the size of the ear hole ( 130) may be included. Here, the ear tip 100 may be composed of a soft elastic injection molding material based on silicone or rubber.

The fixing part 110 may be formed in the form of a rim having a shape and thickness corresponding to the fixing part of the earphone head 200 . In one embodiment, the fixing part 110 may be made of an inward-turning annular protrusion fitted into an annular groove formed on the rim of the main body in the output direction of the earphone head 200, and conversely, the main body in the output direction of the earphone head 200. It may also consist of an inwardly turned annular groove fitted into an annular projection formed on the rim.

In one embodiment, the fixing part 110 may be formed in a cylindrical shape in which a hole penetrating the front and rear surfaces is formed in the center, and the earphone head ( 200) may be fixed to the ear tip 100.

The elastic wearing part 130 may include a plurality of wing pieces 131 extending from one side of the fixing part 110 in the output direction. The plurality of wing pieces 131 are disposed in the shape of a propeller on the fixing part 110, and when worn, their organic action can form an air circulation structure between the inside of the external auditory meatus and the outside of the ear, which is characteristic of the present invention. Available in free size.

In one embodiment, each of the plurality of wing pieces 131 has a constant inclination angle θ with the outer circumferential surface of the fixing part 110, and may extend from the fixing part 110 in the output direction. Here, the plurality of wing pieces 131 is composed of four, but is not limited thereto and may be composed of variously, such as two, three, or six.

In addition, each of the plurality of wing pieces 131 may be radially fixed along the outer circumference of the fixing part 110 and may be formed in a spiral propeller shape bent in one direction. Here, the bending angle of each of the plurality of wing pieces 131 may be determined in consideration of smooth air flow in the overlapped state with adjacent wing pieces. For example, each of the plurality of wing pieces 131 may be formed in a non-linear manner so that the wings are bent more inwardly and less bent toward the outside, but the degree of bending gradually decreases, and the plurality of wing pieces 131 When folded, an air circulation structure may be formed due to the space between overlapping portions. In one embodiment, each of the plurality of wing pieces 131 may be formed to extend in a propeller shape from one side opposite to one side of the through hole of the fixing part 110 to which the earphone head 200 is fixed. Both sides of each of the plurality of wing pieces 131 may be formed in a curved surface, and bent toward the rear end toward the edge, and the bending angle may be elastically adjusted according to a structure such as the inner diameter of the user's external auditory canal.

The thickness of each of the plurality of wing pieces 131 becomes thinner from the center of the wing to the edge and gradually becomes thinner from the fixing part 110 toward the distal end, so that the wing piece 131 is rolled and the thickness is relatively thick The inner part maintains the shape of the ear tip 100 when worn in the ear hole, while the outer part, which has a relatively thin thickness, expands and contracts while the diameter changes as the wing piece 131 is unfolded or folded in a folded state. .

Each of the plurality of wing pieces 131 may be formed to have a specific gap between the wings so that the wings do not overlap or overlap to a minimum when rolled inside, so that an air circulation passage is formed between the wings. Here, the specific distance between the blades of the plurality of wing pieces 131 may vary depending on the outer circumference of the fixing part 110, the number of wing pieces, and the width of the wing pieces. The air circulation passage 133 facilitates the folding of the plurality of wing pieces 131 when the ear tip 100 is inserted into the outer ear canal, thereby facilitating insertion when worn, as well as passing between the folded plurality of wing pieces 131. Allow air circulation to occur. The plurality of wing pieces 131 may be rolled inside within a specific interval and folded without overlapping each other to induce a smooth flow of air.

7 is a view explaining the operation of the ear tip according to the present invention.

Referring to FIG. 7 , the ear tip 100 according to the present invention has a propeller-type elastic wearing part 130 at the opposite part of the end coupled to the earphone head 200 of the fixing part 110, so that air can be released through the configuration. A circulation function and a free size function can be implemented. The ear tip 100 allows the earphone to be worn by inserting the fixing part 110 into the ear hole through the elastic wearing part 130 in a state in which the fixing part 110 is coupled to the earphone head 200 and fixed. At this time, the elastic wearing part 130 is worn according to the size of the ear hole while the plurality of propeller-shaped wing pieces 131 are rolled inward along the ear hole. Since the plurality of wing pieces 131 have a certain inclination angle with the outer circumferential surface of the fixing part 110, insertion into the external auditory meatus is easy, and the earphone can be prevented from being separated by the action of the wing pieces 131 having an inclination angle during use. In this process, the air circulation passage 300 may be formed by the gap between the plurality of wing pieces 131 . Here, the degree to which the plurality of wing pieces 131 are rolled inside varies according to the size of the ear hole, and accordingly, the size of the air circulation passage 300 can be changed.

Eartips having an air circulation structure according to an embodiment can be fitted into ears of various sizes through propeller-shaped elastic wearing parts, and mold is generated due to high temperature and humidity in the ear due to air circulation, resulting in severe itching or pain due to mycosis of the ear canal. symptoms can be prevented.
