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.

摘要： Provided are a mobile terminal and a drop protection method thereof. The mobile terminal includes a display panel, a middle frame, a rear shell, a protection module and a detection module; the middle frame being mounted in the rear shell; and the display being arranged on the middle frame. The protection module includes a buffer elastic block mounted on the middle frame and an elastic block control unit for controlling buffer elastic block to eject out if the mobile terminal is in a drop state. At the instant of dropping down to the ground, the buffer elastic block absorbs a generated momentum reduces instant impact stress of mobile terminal, thereby protecting modules, and preventing stress concentration. Since buffer elastic block is arranged on middle frame, the mobile terminal is better protected, and damages to the screen and the internal modules caused by drop of the mobile terminal are be avoided.
