发明名称 EARPHONE-MICROPHONE-EARMUFF ASSEMBLY
摘要 The main components of an earphone-microphone-earmuff assembly are an earphone, a microphone and an earmuff. Besides using the assembly as a whole, each component can be independently used as well. The assembly has several parts including a mounting cap, an earphone, an earmuff, and each part has its own mounting structure or structures for interconnection. In operation, the mounting cap and the earphone can be assembled together just for listening. Alternatively, the mounting cap and the earmuff can be assembled together just for ear warming or noise shielding. However, the mounting cap, the earmuff and the earphone can all be put together for hearing, ear warming and noise shielding. Furthermore, a microphone can also be installed on the earphone for easy communication.
