SWITCHING APPARATUS OF HEAD SET CAN CONNECT TO MOBILE PHONE WHILE HEARING STEREO MUSIC SOUND

摘要

The subject innovation is music to reduce power consumption by operating only when the normal environment, but has to standby mobile phone response signal detected, and prevent malfunction by determining the reception state of the mobile phone to detect with the mobile phones response signal and the Ring / vibration signals appreciation that of about headset switching device that can be connected to mobile phones, mobile phones and close to be installed, upon detecting a response RF signal from the mobile phone via the antenna and, at the same time, when the called via the microphone detection for detecting a ring tone or a vibration signal from the cellular phone unit .; Connecting the base end to the sensing portion side, and the generated, it connects the emitter to the battery side, hayeoseo install the resistance R1 between the collector and the base, and the consumption current is generated by the response RF signals sensed by the sensing resistance R1 a transistor which is operated by a voltage; A low-dropout voltage circuitry; Low voltage detector; Power holding section; Signal amplifier and a level comparator; The low-voltage and lowering the constant voltage circuit and a power holding section operating at a voltage which is supplied from, generates each separated sound that corresponds to a comparison of the state determined in the mobile phone an incoming signal and battery-voltage detection from the sensing unit, the this relay operation through the control unit to output to the earphone of the headset; The consists of a first switch.
