Foam material embedding device for embedding earphone has earphone layer between upper and lower foam layers, such that a funnel-shaped hole layer is formed on top of the upper foam layer

摘要

A frame has rounded corners. A funnel-shaped hole layer (1) is formed on the top center of the frame. The earphone (5) is embedded under a foam layer (2). A foam layer (4) is formed under the earphone layer. Preferably, a plastic foam layer is provided between foam material (2) and earphone layer (3), and between earphone layer (3) and foam layer (4).
