An effect unit based on dynamic circuit modeling method that can change effect wirelessly, comprises a sound effect algorithm database, a mobile APP client and a sound effect device. The mobile APP client checks updates of the sound effect algorithm database, downloads new sound effect algorithms to the local device and displays the same in the form of a list, and the sound effect algorithms are downloaded to the sound effect device in a wireless communication mode by opening the wireless communication function of the mobile APP client; analog signals sent by an electrophone are converted into digital signals by ADC, the digital signals are processed by a DSP sound effect algorithm in the sound effect device, then the digital signals are converted into analog signals by DAC, and the analog signals are output by sound effect output equipment.
