The Sound touch wall senses the customer's touch action through a capacitive sensor. The capacitive sensor is embedded in the wall, and after sensing the customer's touch, it will play the audio file (MP3, WAV, etc.) pre-stored in the control panel. Or, it can automatically recognize that the customer touches several sensors at the same time, and play different audio files. The picture of the wall can be customized according to the customer's picture. Up to 24 sensors are possible. Suitable for all kinds of music, sound effects, voice interactive scenes.
