The Pordi Air Piano uses infrared sensing technology. When a person stands in front of the piano and places their hands over the holes, it triggers sound effects, producing pleasant music and bringing joy and happiness. By using the power button and pitch button, the mid, high, and low tones can be freely switched, creating fluctuations in the music’s pitch, enhancing the interactivity and enjoyment of outdoor activities. The Pordi Air Piano combines various cutting-edge technologies such as sound, light, and electricity, suitable for people of all ages. It can be applied in outdoor spaces and halls of early childhood education institutions, and can also be placed in greenway micro-parks, hotel lobbies, children’s playgrounds, and any other location. When using and operating it, users experience physical and mental pleasure, putting them in a positive and excited emotional state, increasing the sustainability of outdoor activities and dispelling physical fatigue. For children, operating the air piano promotes relaxation, positive emotions, and further develops their hand-eye coordination. Casually creating beautiful music can make children fall in love with and enjoy music, sparking their interest in further learning about music and musical instruments.
