摘要： A sound production device, a display system, and a sound production method for a sound production device. The sound production device includes ultrasonic transducers, a sounding control unit, and a motion unit. The ultrasonic transducers can constitute at least one sounding unit, each of the sounding units includes two ultrasonic transducers, and one ultrasonic transducer in each sounding unit emits a first ultrasonic wave, and the other ultrasonic transducer emits a second ultrasonic wave. The sounding control unit is configured to determine a target direction and output a direction command to the motion unit according to the target direction. The motion unit is configured to adjust a sounding direction of each ultrasonic transducer according to the direction command, such that two ultrasonic transducers in each sounding unit emit sound toward the target direction to generate a difference frequency sound wave within an audible frequency range in a target area.
