The present invention relates to a molded earphone, and more specifically, by forming and providing earphones corresponding to the external shape of a specific person, excellent wearing comfort, fatigue does not feel even after long use, effectively blocks outside noise and good sound quality It relates to an earphone that can provide.

Headphones or earphones are mainly used as a portable sound device, and in particular, the earphones are lightweight and small in volume compared to the headphones, so they are easy to wear and carry. Due to these characteristics, earphones are used as portable sound devices for audio devices such as radios, cassette tape players, and compact disc players, and for other purposes, they are also used as ear microphones that are connected to a mobile phone with a microphone.

However, since each user using the earphone has a different ear shape, earphones that are standardized and mass-produced are small and can be worn loosely. On the contrary, they are too large compared to the outer ear, which may cause pain to the wearer. In addition, even if the first wearing is comfortable, the wearer is tired as the time of continuous use elapses.

In addition, long-term use may cause hearing loss because earphones that do not fit the outer ear induce a user to use excessively large volume. In particular, the problem of using the earphone is a social issue for adolescents who use the earphone a lot in music listening or language practice.

The contents of several conventional patent applications for comfortably using such earphones are as follows.

1) An impression material 520 is provided in which a prosyl and a prosyl hardener are mixed in a one-to-one manner. When the prosyl and prosyl hardener are mixed, the impression material 520 gradually cures over time. It is preferable to mix the prosyl and its curing agent in a one-to-one manner, but the mixing ratio may vary depending on the time and conditions required for curing.

2) The impression material 520 is injected into the outer ear 510 of a specific person through a filled syringe 525. The syringe 525 scans the impression material 520 while moving outward from the inside of the outer ear 510, and the impression material 520 is not injected at a deep point of the ear canal but at a depth enough to form a molded earphone. If injection is enough. Therefore, it is harmless to the human body and not dangerous.

3) The injected impression material 520 hardens over time to form the outer ear model 530. The time that elapses for the impression material 520 to cure is preferably 1 to 2 minutes.

4) The outer ear model 530 is separated from the outer ear 510 and then cut and trimmed with a knife and processed. During processing, the rough face of the outer ear model 530 is trimmed and the outer ear model 530 is cut to an appropriate size.

5) The outer ear model 530 is immersed in a wax 535 at about 60 ° C. to adjust thickness and surface roughness. The thickness of the outer ear model 530 is adjusted while repeatedly dipping the outer ear model 530 in the wax 535. The reason why the outer ear model 530 is immersed in the wax 535 is to smooth the rough surface of the outer ear model 530 and to finely adjust the size of the molding housing that is produced by adjusting the thickness of the outer ear model 530. .
