Low-Frequency Application Device

摘要

There is provided a low-frequency application device capable of applying a low-frequency voltage in synchronization with emitted music and preventing an unexpected large voltage from being suddenly supplied to a human body. A w-frequency application device, comprising: an audio processor to output audio signals; a filter to pass audio signals in a predetermined frequency band among the audio signals; a signal generator to generate a pulse signal by receiving an audio signal at a preset level or higher among the audio signals passed through the filter; electrodes to supply current to a human body; a voltage generator to generate a low-frequency pulse voltage to supply current corresponding to the voltage to the electrodes; and a controller to control output of the voltage by the pulse signal.
