Apparatus with mechanical electric energy generation for audio processing

An apparatus comprising:

• a mechanical module;
• an electronics module including a microphone, a non-volatile memory, and a speaker, wherein the electronics module is configured to record an audio with the microphone into the non-volatile memory, and to play the audio from the non-volatile memory with the speaker;
• and
• a designed housing;
• wherein the mechanical module includes an interface configured to receive rotation from a user, a disc-shaped flywheel rotor embedded with a plurality of permanent magnets and configured to rotate next to a disc-shaped stator, and a gearing coupled from the interface to the disc-shaped flywheel rotor and configured to increase speed of the rotation,
• the electronics module includes a disc-shaped stator embedded with a plurality of coils and configured and positioned next to the disc-shaped flywheel rotor to generate electric energy for powering the electronics module during rotation of the disc-shaped flywheel rotor, and
• the designed housing is configured to accommodate and protect the mechanical module and the electronics module.
