1. A method comprising:
determining, based on (i) audio data, (ii) characteristics of a flexible electrical-to-mechanical (E-M) transducer, and (iii) an error representing a mismatch between expected sound waves and sensed sound waves, a voltage signal to apply to the flexible EM transducer; and
applying the voltage signal to the flexible E-M transducer to mechanically contract, expand, or vibrate the flexible E-M transducer to alter a shape of a pinna of a human ear to which the flexible E-M transducer is conformed, the alteration of the shape creating sound waves in the human ear, the sound waves reproducing, in analog form, the audio data.
