Piezoelectric Earphone for ANC with Built-In Microphone

Original language description

Electrodynamic acoustic transducer in headset/earphone with active noise control (ANC) system has some features which complicate design of ANC system. Its higher power demand challenges usage of power amplifier, its bigger group delay causes bigger geometry of the ANC system in respect to keep causality. Wide frequency transfer function of acoustic transducer brings on necessity to use an interpolation filter adding delay and makes ANC headset system larger. Piezoelectric transducer in newly designed earphone with built-in microphone was solution.
