Hybrid Power System Analysis
⚡ System Schematic
This schematic illustrates the flow for a theoretical hybrid-powered speaker system. It features two independent paths: a Power Path for harvesting ambient energy and a Data Path for receiving the audio signal.

π Appendix: System Calculations & Statistics
The following calculations model the performance of this theoretical system based on a set of optimistic, cutting-edge component assumptions.
1. Core Component Assumptions
| Component | Specification | Value |
|---|---|---|
| Energy Storage | 18650 Li-ion Battery | 3.7 V, 3000 mAh |
| Total Capacity | (3.7 V * 3.0 Ah) | 11.1 Wh |
| Energy Consumption | Hypothetical Graphene Speaker (RMS) | 50 mW (0.05 W) |
| Energy Generation | Hypothetical Harvesters (Li-Fi + Wi-Fi) | 15 mW (0.015 W) |
2. Runtime Calculation: Baseline (Battery Only)
This determines how long the speaker will run on a full battery with no harvesters attached.
11.1 Wh / 0.05 W = 222 hours
(Equivalent to 9.25 days of continuous runtime)
3. Runtime Calculation: Hybrid System (Battery + Harvesters)
This determines how long the speaker runs with the harvesters actively slowing the battery drain.
0.05 W - 0.015 W = 0.035 W (35 mW)
New Runtime Calculation: Total Battery Capacity (Wh) / Net Power Draw (W)
11.1 Wh / 0.035 W = 317.14 hours
(Equivalent to 13.21 days of continuous runtime)
4. Final Extension Time Calculation
This shows the "extra" runtime provided by the hybrid harvesting system.
317.14 hours - 222 hours = 95.14 hours
The harvesters provide an additional ~95 hours (or 3.96 days) of runtime, representing a 42.8% improvement in battery life.
