Structure of an andio device
First Claim
1. A structure of an audio device for receiving an audio signal, comprising:
- a housing accommodating a circuit board, at least a speaker, and at least an optical trace detecting module;
wherein the circuit board has a micro control unit and a memory;
the speaker is coupled to the circuit board; and
the optical trace detecting module is coupled to the micro control unit;
wherein the optical trace detecting module at least has a light source and a image sensor for detecting a user'"'"'s finger moving thereon so as to generate a corresponding moving signal, which is supplied to the micro control unit;
whereby, in response to the moving signal, the micro control unit generates a first control signal for adjusting the audio signal.

Abstract
An audio device or system includes a housing which accommodates a circuit board having a micro control unit located within the housing, at least a speaker, and at least an optical trace detecting module coupled to the micro control unit. The optical trace detecting module at least has a light source and an image sensor for detecting a movement of a user'"'"'s finger moving thereon so as to generate a corresponding moving signal, which is supplied to the micro control unit to cause the micro control unit to generate a control signal for adjusting a received audio signal. The micro control unit may be used in place of a rotary audio adjustment button or knob.

15. A method for adjusting an audio signal, comprising:
-
providing a housing for accommodating a circuit board and at least an optical trace detecting module; causing the optical trace detecting module to detect movement of a user'"'"'s finger thereon so as to generate a corresponding moving signal and supplying the moving signal to a micro control unit of the circuit to cause the micro control unit to generate a first control signal for adjusting the audio signal; moving the optical trace detecting module relative to the housing so as to cause a micro switch next to the optical trace detecting module to generate a second control signal.
