Zusammenfassung: | The embodiment of the invention provides a gesture recognition method, electronic equipment and a storage medium, and relates to the technical field of communication. Using a plurality of microphones to receive ultrasonic echoes corresponding to the ultrasonic waves to obtain a plurality of first sound wave signals; according to a gesture recognition area, accumulating the plurality of first sound wave signals to obtain a second sound wave signal, the gesture recognition area being a frequency area associated with a preset frequency, and the amplitude of the second sound wave signal in the gesture recognition area being greater than the amplitude of each first sound wave signal in the gesture recognition area; and performing gesture recognition according to the second sound wave signal. According to the method provided by the embodiment of the invention, the gesture recognition distance can be increased.
