Abstract
An extension flash module is provided in the present invention. The extension flash module adopts xenon flash light and is for attaching on the headphone jack of a mobile device. When the extension flash module operates, the voltage output from the headphone connector is boosted to provide a high voltage to the extension flash module. When the high voltage is charged to a rate voltage, the extension flash module sends a charging complete signal to the mobile device through the microphone terminal of the headphone connector. When shutter instruction is performed, the mobile device triggers the extension flash module to flash.
