The fourth figure is a schematic diagram of the circuit block of the present invention. The device for combining the main headphone and the sound reinforcement base of the invention comprises a blue machine and a sound reinforcement seat. The fifth figure is a schematic diagram of the internal circuit of the sound reinforcement base of the present invention, which has: - control After the device 21, the gram wind 24 is operated. The controller 21 is a model FM1182 connected to the electric tuner 23, which is composed of a model leg_compound integrated circuit and other electronic components, and a microphone 24 21 electrical connecting component C1. The controller has a transmission port 1 and a 1:2 signal transmission terminal 10, which is electrically connected to the poor material transmission and data processing through the signal 23. The speaker is controlled by the controller 2, and is controlled by the controller 21, so that the two are connected to the controller 21, and the controlled button is provided for the sound capturing function. Four diagrams 'When the remote mobile phone (not marked) calls, the control telecommunications fee si ^ headset 1 obtains an incoming call signal S1, and then the incoming bud headset is placed in the amplified seat 2, the sound reinforcement seat 2 Provide blue-sounding sound (Ε_'s two-seat 2 controller 21 has the elimination of the common Bluetooth headset. 1 The connection action is as follows: When the mobile phone calls, the bud headset 1 transmits the audio channel. The incoming call signal S1 is extended via blue] The controller 21 of the base 2 performs processing, and the controller 21 transmits the incoming signal si through the internal analog/digital converter to the first digital signal and records the 'after a digital/analog signal converter'. The incoming call signal of the caller is amplified by the speaker 23 and the listener hears it. Since the sound reinforcement seat 2 functions as a sound amplification function, the volume emitted by the speaker 23 is very loud, and the microphone 24 receives the volume. That is, a black horn is generated. The control state 21 converts the resonance signal into a second digital signal through the internal analog/娄 bit converter, and compares it with the face _1st bit signal. If the second Digital signal conforms to the first digit When the number is not used, the controller 21 suppresses the second digital signal to achieve the function of eliminating the resonance sound (ECHO). With the fifth figure, referring to the fourth figure, the sound reinforcement base 2 of the present invention further includes a function key. Unit 28, the function key unit is formed by the resistance elements R56, R57 connected to the switch Sb S2.
