Viewed from above the Altar, the Source's two coils face each other like orange wedges, each spanning nearly half the Resonator's rim.
The Belluaire Component converts acoustic resonance into electrical energy, but the part that starts that whole process has nothing acoustic about it at all. The Source is the electromagnetic driver of the Infrasonic Reactor +Source: a pair of coils whose only job is to force the Component's main Resonator — a ferromagnetic, bell-shaped element — into ringing. Viewed from above the Altar, with the Pedestal standing perpendicular at its center, the Source's two coils face each other like wedges of an orange, each spanning nearly half of the Resonator's rim.
The Source: A Symmetrical Design
The Source sits on the Altar's second step as two semi-circular electromagnetic coils, flanking the Resonator from opposite sides of its base. Laid out this way — wedge against wedge, together tracing almost the full circumference of the Resonator's rim — the two coils generate an electromagnetic field strong enough to pull the ferromagnetic Resonator first toward one coil, then the other, making it bow or knee rhythmically between them. That symmetry is functional, not decorative: a coil positioned on only one side would pull the Resonator off-axis permanently and leave it there; two coils facing each other, energized in turn, keep that same pull alternating back and forth instead, which is what turns a one-directional tug into a sustained, rhythmic rocking motion. The coils never touch the Resonator at any point in this process — the force is purely electromagnetic, transmitted across the small working gap the Altar's second step is built to hold. The Resonator itself rides on the Pedestal below it, a spring-compliant vertical mount that holds the Resonator and its Load as an inverted pendulum — free to tip toward each coil and spring back on its own, rather than fighting the motion the Source is trying to induce.
Electromagnetic Drive, Not Acoustic Harvesting
Given how central acoustic resonance is to the rest of the Belluaire Component, it's tempting to assume the Source itself taps into ambient sound or infrasonic energy in the air. It doesn't, and the distinction matters. The Source runs on ordinary electrical input, full stop — its coils do nothing but generate an electromagnetic field, the same basic physics as any solenoid or electromagnet. There is no ambient energy being harvested at this stage; the Source is a driver, not a collector. Acoustic behavior only enters the picture once the main Resonator starts ringing: because the Resonator is ferromagnetic and tuned to the activated medium's key frequency, its mechanical ringing propagates outward and sets every other correctly-tuned Resonator in the array ringing too — not because the Source reaches them directly, but by sympathetic resonance, the same way one tuned bell struck in a room sets a second, identically-tuned bell humming nearby without ever being touched. Everything acoustic about the Belluaire Component happens downstream of the Source, never inside it.
The Role of the Source in the Belluaire Component
That handoff is why the Source matters structurally, not just mechanically. Because sympathetic resonance does the work of reaching every other Resonator in the array, the Infrasonic Reactor +Source is the only Reactor in the whole Component that needs a direct electrical input at all. Every additional Reactor rings in sympathy with the one Resonator the Source drives, picking up the shared key frequency on its own and converting it into output through its own Load and Collector — without the Source driving it, or needing to know it exists. That is the leverage the whole design is built on: one electromagnetic driver, feeding one Resonator directly, can set an entire array ringing at no extra electrical cost per Reactor added.
Engineering Precision and the Path Forward
The precision engineering of the Source — two matched, symmetric coils doing nothing more exotic than generating a clean electromagnetic field — is what makes that leverage reliable rather than accidental. Each part, from the Platform to the Dome, is built to support the Resonator's ringing once the Source has started it; the Source's only responsibility is to start that ringing cleanly, on-frequency, every time. That narrow, well-defined job is exactly what lets the Component scale by adding Reactors instead of adding Sources: the electromagnetic drive stays a one-time, fixed cost, while the acoustic side of the system — the part that actually does the work of reaching every other Resonator — scales for free.
