Alta Controller
- Companion chip for Cypress
- Modulates carrier signal with audio signal
- Generates carrier (Sm) and synchronized demodulation signal (Sv) for Cypress
Cypress Speaker
- Pressure modulator and demodulator
- Membrane(s), driven by Sm produces ultrasonic modulated pressure in chamber
- Valves (Sv) are driven to demodulate ultrasonic pressures, generating pulses
- Audio signal is generated with high fidelity from envelope of pulses
