Abstract:
An earphone includes a basket defining a through hole. A leading wire board fixed underneath the basket has a pair of solder foils on a bottom surface thereof. A magnet unit is located in the basket with the through hole adjacent to a side edge of the magnet unit. A diaphragm is arranged on the basket and over the magnet unit. A voice coil is fixed to a bottom of the diaphragm and surrounding the magnet unit. The voice coil has two leading wires. Each leading wire passes through the through hole of the basket and further bends to solder with the corresponding solder foils of the leading wire board.
