Description

Double-colored shaping structure and neck wear earphone

Technical Field

The utility model relates to a double-colored forming structure and neck wear earphone.

Background

The neck wear rack of the neck wear type earphone double-color forming structure is generally formed by forming a circle of shell (silica gel, rubber or soft plastic) outside a lead, so that the neck wear rack with the soft and protective function is obtained. In order to produce a better appearance, the protection strips of two colors are selected to wrap the wires in the actual process, and the neck-wearing frame is obtained after thermoforming.

In the traditional process, the protective strips with two colors are symmetrically arranged, so that the obtained neck wear frame has two colors which are symmetrically distributed. In the current new product demand, two colors are required to be asymmetrically distributed on the neck wear rack.

Referring to fig. 1, when two colors are asymmetrically distributed on a neck wear frame, if a conventional molding structure is adopted, the color mixing phenomenon is easily generated at the joint due to the different thicknesses of the joint of the

protective strips

01 and 02 of the two colors.
