At this time, the coupling part 1210 corresponds to a circle-shaped part of the shape of a magatama, and the wing part 1220 corresponds to a horn-shaped part of the shape of a magatama. However, the shape of the support portion 1220 is not limited thereto, and may be any shape conforming to the shape of the outer ear.

By having such a shape, the wing portion 1220 is more firmly fixed to the outer ear of the user. At this time, the outer ear of the user is, for example, the cymba concha. That is, the wing portion 1220 includes all shapes that are the same as or similar to the shape of the user's yigap revision.

The coupling part 1210 according to the embodiments is coupled to the inside of the housing 1100 or one surface of the housing 1100 . The coupling part 1210 has a hole 1211 therein to be coupled with the housing 1100 . The holes 1211 are formed to be coupled to each other based on the outer surface size of the housing 1100 .

In FIG. 5 , only small-sized supports are shown, but all support parts 1200 have holes 1211 regardless of the size. The hole 1211 makes the support 1200 compatible with the housing 1100 regardless of size.
