Veylcoil / field notes
Questions worth answering before the coil meets the product.
Inductive power for untethered Bluetooth sound. These answers keep the conversation close to geometry, energy balance, and the listening pattern that the hardware must actually support.
Qualification lens
Measure the source, the buffer, the load, and the moments when sound is required.
