Abstract

The invention relates to preparation of a health care earphone. The main structure of the health care earphone comprises an inner shell cover, a ring shell body, an outer shell body, an earphone body, an earphone base, and an earphone frame. The convex arc-shaped round inner shell cover is arranged on a nested structure on the top side of the earphone body of a ring cavity structure. A plurality of opened or drilled voice-through needlelike holes are evenly distributed on the inner shell cover. The outer shell body made of a rubber-plastic material is arranged in an embedding way at the connecting portion of the earphone body and the earphone base. The alloy ring shell body of a ring-shaped structure is sleeved between the inner shell cover and the outer shell body at the periphery of the earphone body in an embedding way. The elastic earphone frame is integrally arranged at the lower portion of the earphone base. The health care earphone has a simple structure and a beautiful and decent appearance, and is convenient to machine and manufacture and easy to popularize.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of earphone preparation, and relates to an improvement in the structure of earplugs or earphones, in particular to the preparation of health-care earphones. [0003] Background technique: [0004] Earphones are a very frequently used sound output tool for wireless and wired communicators, especially for teenagers and college and middle school students, the use of earphones has been quite extensive. Since the earphone can form a private space around the user, it is convenient to enjoy the fun of music alone without affecting others.

AI Technical Summary

Problems solved by technology

Most of the existing earphone shells are made of rubber and plastic materials or general stainless steel materials. During use, due to the contact between the shell and the human body, there will be friction and static electricity, which will cause adverse harm to the human body to varying degrees, especially In summer, due to sweating and other reasons, the rubber or plastic earplug shell will rub against the user's auricle for a long time, which will cause discomfort in the user's ear and cause ear redness and inflammation, which is easy to damage the user's ear health. cause adverse effects

So to sum up, the existing earphones have disadvantages such as unattractive structure, high cost of shell material preparation, and easy to cause discomfort or certain harm when in contact with the human body, especially due to the long-term contact of rubber and plastic materials with the human body. Static electricity has adverse effects on the user's ear nerves, and even causes harm
