WIPO Patent Application WO/2012/060043
Kind Code:
A1
Abstract:
This electronic device (100) is provided with: a video projection unit that projects a video screen (14); an oscillation device that oscillates ultrasonic waves (26) for replaying audio and ultrasonic waves (24) for a sensor towards the video screen (14); a control unit that controls the oscillation device; and a sound wave detection unit that is connected to the control unit. The sound wave detection unit detects the ultrasonic waves (24) for the sensor that have reflected from the video screen (14). Also, the control unit adjusts the sound pressure of the replayed sound on the basis of the detection strength of the sound wave detection unit. As a result, it is possible to reduce the power consumption of the electronic device.
