Introduction: In the year 2021, Audfly Ultrasonic Directional Speaker was introduced into some gas stations to deliver advertising audio information to the target customers. When people pass by the gas station or the bathroom in the service area, when they wash their hands at the sink, they can hear the audio sound of the advertisement from the ceiling of the sink by Audfly in ceiling directional speakers, which attracts the attention and interest of customers and effectively spreads the advertisement. A directional speaker is installed on a sink, and you can only hear the sound when you walk directly under the washbasin, and there is almost no sound around, which also effectively protects the surrounding quiet sound environment.
