  "textContent": "The disclosure provides a detection signal for detecting a power receiving device in wireless charging, wherein the detection signal is configured to wake up the power receiving device in a wireless charging field, and cause the power receiving device to generates a feedback signal based on a modulation wave of about 2kHz; a duration time of the detection signal is greater than 1 millisecond and less than 65 milliseconds; and the detection signal is configured to identify the modulation wave. The disclosure further provides a wireless charging method for a wireless charging device using the detection signal, and a wireless charging device using the detection signal.",
