Abstract
As part of my ongoing work with speakers that use uncommon technologies to project sound, this time I turned to the vibration speaker, a kind of transducer that, in order to radiate sound, coaxes a surface to vibrate by direct contact. Therefore, in this article, pros and cons of vibration speakers will be highlighted and, at the same time, I will proceed to illustrate a piano suite I assembled that uses an expressly built-for Android application as an interface between whatever sound is produced in, on or with the piano and the vibration speaker: the sound is captured by the microphone of the Android device, then it is processed by the application and eventually is sent via Bluetooth to the speaker sitting on the piano soundboard, through which it gets amplified. This relatively simple system allows for a large array of timbral possibilities and unconventional ways of playing the piano.
