Title:
Ultrasonic Audio-spot and Potential Applications in Internet of Things

Abstract:
Generally, electro-dynamic loudspeakers are widely used for speech and music
reproduction. However, the spreading sounds may become noise for non-target listeners
nearby. In contrast, parametric array loudspeaker can reproduce audible sounds in a
narrow area along the propagation axis utilizing the straightness of ultrasounds.
Therefore, an audio-spot can be constructed by parametric array loudspeaker that the
audible sound can only be heard at this spot. In this talk, the basic principles on
ultrasonic audio-spot will be introduced. Recent studies on parametric array loudspeaker
for performance improvement and novel applications will also be presented. Moreover,
the potential applications of ultrasonic audio-spot in internet of things will be discussed.
