Portable audio player with alternative operation interface and expanded function
First Claim
1. A portable audio player comprising:
- a built-in operation interface for inputting a first command therefrom and generating a first control signal in response to said first command;
a main circuit for processing and optionally storing audio data; and
a microcontroller in communication with said built-in operation interface, said main circuit and an external operation interface for controlling said main circuit to process said audio data optionally in response to said first control signal or a second control signal generated by said external operation interface.

Abstract
A portable audio player includes a built-in operation interface for inputting a first command therefrom and generating a first control signal in response to the first command; a main circuit for processing and optionally storing audio data; and a microcontroller in communication with the built-in operation interface, the main circuit and an external operation interface for controlling the main circuit to process the audio data optionally in response to the first control signal or a second control signal generated by the external operation interface. The external operation interface may include a specific control program installed in a computer system, and the microcontroller may communicate with the external operation interface via a USB interface.

16. An audio player for use with a computer system, comprising:
-
a microcontroller communicable with said computer system via a USB interface;
a built-in non-volatile memory unit for storing first audio data in a digital form; and
an audio decoder coupled to said built-in non-volatile memory unit and said microcontroller for converting said first audio data read from said built-in non-volatile memory unit from said digital form into an audible form, and differentially adjusting gains of said first audio data at different frequency sections under the control of said microcontroller in response to a first control signal from said computer system. - View Dependent Claims (17, 18)

19. An audio player for use with a computer system, comprising:
-
a microcontroller communicable with said computer system via a USB interface;
a tuner for receiving radio signals as first audio data and outputting said first audio data in an analog form; and
an analog-to-digital converter coupled to said tuner and said microcontroller for converting said first audio data received from said tuner from said analog form into a digital form and transmitting said first audio data in said digital form to a computer system to be stored under the control of said microcontroller in response to a first control signal. - View Dependent Claims (20)
