Method of manufacturing a microphone assembly

A method of manufacturing a microphone assembly having an ear set function, the method comprising:

• assembling a mike cell unit;
• obtaining a region for connection with the mike cell unit on a printed circuit board (PCB), mounting only a conductive member in the region, and mounting other remaining components outside the region;
• adhering the mike cell unit to the region of the PCB;
• and
• sealing an adhering portion between the mike cell unit and the PCB,
• wherein the assembling of the mike cell unit comprises:
• inserting a mike cell case comprising a sound hole and a curing portion into a diaphragm assembly;
• stacking a spacer on the diaphragm assembly;
• inserting a back electrode plate into an insulating ring base to be coupled to each other;
• mounting the insulating ring base coupled to the back electrode plate on the spacer;
• mounting a metal ring base on the insulating ring base;
• and
• curing or clamping the curing portion of the mike cell case.
