This work explores how wireless, self-contained CMOS synthesizers with built-in speakers can enable low-threshold interaction with multichannel sound fields. Using deliberate low-tech and DIY approaches, simple sound modules are developed for music interaction and education, prioritizing accessibility of the technology.
The modules are powered via wireless power transfer (WPT). A multichannel sound field can be generated and shaped by arranging several sound objects near induction coils — repositioning, moving, or grouping the modules produces direct alterations in sound. Although the objects are not physically connected, they begin interacting electro-acoustically when they share the same magnetic field. Equipped with electronic sound generators and transducers, the modules operate independently of a studio environment.
