HANDHELD STRUCTURE FOR PORTABLE HIGH FIDELITY MUSIC PLAYBACK

摘要

A portable housing structure of an audio data processing device having a rotatable knob for inputting user commands, and a touch screen display on the side wall. The rotary knob is coupled to a rotary encoder and a power management circuit is coupled to push-button. A plurality of functional components installed on this portable audio data processing device in responding to said knob's rotation.

主权项

1. A handheld structure for a portable audio data processing and playback device, comprising:
a housing having a top side, a bottom side, and enclosed a wall, wherein said housing is configured to be held by a human hand; an aperture is disposed on said top side; a rotatable part is rotatably mounted on said aperture, said rotatable part being a cylindrical tubular structure, having a first opening and a narrowed second opening; a rotatable knob case is coupled to said first opening fixedly and fitly, wherein said rotatable knob case is configured for hand-gripping; a rotary encoder being fixedly coupled with said second opening of said rotatable part so that rotating of said rotatable knob case causes rotation of rotatable part and said rotary encoder; and a primary PCB board electrically wired with a set of circuits and multi-core micro-processors for processing high density audio data, said primary PCB board is configured in electronic communication with said rotary encoder, when system power is on, a rotation of said encoder sends an electronic signal to said primary PCB board to be executed as a command.
