directional_speaker

The Ultrasonic Directional Speaker repository provides C++ code for the STM32 Microcontroller and KiCad schematic images for the circuit and transducer array, facilitating the construction of an affordable laser directional speaker, also known as a parametric speaker. Its primary use case is in creating directed audio applications where sound is focused in a narrow beam. Notable features include low-cost components and detailed schematic guidance for building the speaker system.
