Creation Instructions (i) [Technical Field to which the New Type belongs] This creation relates to an adapter, and in particular to an adapter for connecting a ear phone microphone of a mobile phone to a stereo system . [Previous Technology] Due to the advancement of radio technology and semiconductor technology, the size of mobile phones has become increasingly lighter and more versatile, making mobile phones almost one of the indispensable communication tools in today's life. Most of the hands-free handset components (headphones for mobile phones) used with mobile phones before today only provide call functions. But recently, in order to increase business opportunities, various manufacturers are actively launching mobile phones with more additional functions, and people's requirements for mobile phones have become more than just call functions. Recently, some manufacturers have proposed that the mobile phone has built-in FM radio, MP3, and audio and video (V i d e 〇) playback and other entertainment-like additional functions. Therefore, the hands-free handset assembly used with the mobile phone has changed from the original mono headset to a stereo headset with left and right channels, so that the mobile phone user can listen to the FM built-in during the idle time of the call Music programs such as radio, MP 3 and video playback. A mobile phone that can listen to music programs like this is naturally more expensive than a normal mobile phone, and the hands-free handset assembly used with this phone is also more expensive than a general hands-free handset assembly. The difference between the stereo speakerphone assembly for this type of mobile phone and the mono speakerphone assembly for general mobile phones is not only mono 4 channels and stereo channels, but also the sound quality requirements are higher than the general speakerphone components. .
