EAR KEY EQUIPMENT USING VOLTAGE DIVIDER AND WIRELESS TELECOMMUNICATION TERMIANL USING THAT EAR KEY EQUIPMENT

摘要

1. The art that the invention defined in the claims ; Thing of multi-function key followed using the same apparatus and radio communication terminal using the present invention, the voltage distribution ; 2. SUMMARY OF invention to solve the ; The present invention is provided in the earphone ear key device (including the ear microphone) by using a voltage distribution to a predetermined voltage level according to the input signal for each ear key and generating, by the earphone to be associated with the wireless communication terminal receives the voltage level signal through the ear jack single sense terminals thereof perform a predetermined function that maps, various kinds of wireless communication terminals that are associated with using the earphones to allow the remote control function, followed by multi-function key unit, and the purpose is that to provide a radio communication terminal using the same using a voltage divider. ; 3. A base ; This invention is in the solution of the invention, multi-function followed in the radio communication terminal having a key recognition function, each of the digital control signal with a predetermined function performed in the wireless communication terminal is mapped to correspond to each other storage means storing a mapping table in which the control signal; The voltage level signal having a different voltage level from the multi-function key unit of the external ear through the ear jack single sense terminals ear jack for receiving transmission; Signal conversion means for converting the voltage level signal from the ear jack to a digital control signal according to the transmission reception; And retrieve a desired function that is mapped to the digital control signal from the control signal mapping table stored in the storage means by a control means for performing in accordance with the digital control signal delivered from the reception signal conversion means. ; 4. An important use of the invention ; and used to fight the present invention a wireless communication terminal.
