Abstract

The present invention discloses an audio playing system for protecting a storage medium of an electrical device. The audio playing system includes a detecting unit, a processing unit, an adjusting module and a playing module. The detecting unit detects vibration of the electrical device to generate a detection signal corresponding to the vibration. The processing unit compares the detection signal with the tolerable vibration value of the storage medium to generate a comparison result, and generates an adjustment signal according to the comparison result. The adjusting module adjusts an audio file according to the adjustment signal to generate an adjusted audio file. The playing module plays the adjusted audio file. The present invention also discloses an audio playing method for protecting a storage medium of an electrical device.

First claim

What is claimed is:

1. An audio playing system for protecting a storage medium of an electrical device, the storage medium having a tolerable vibration value, and the audio playing system comprising:
a detecting unit configured to detect vibration of the electrical device to generate a detection signal corresponding to the vibration;
a processing unit electrically connected with the detecting unit, the processing unit configured to compare the detection signal with the tolerable vibration value to generate a comparison result, and to generate an adjustment signal according to the comparison result, wherein the tolerable vibration value includes an information associated with acceptable vibration values in different frequencies and the comparison result shows that the detection signal exceeds on the acceptable vibration values in at least one frequency;
an adjusting module configured to adjust the at least one frequency of an audio file according to the adjustment signal to generate an adjusted audio file; and
a playing module configured to play the adjusted audio file.

2. The audio playing system of claim 1 , wherein the adjusting module comprises an equalizer configured to utilize the adjustment signal to adjust the at least one frequency the audio file for generating the adjusted audio file.

3. The audio playing system of claim 1 , wherein the adjusting module comprises a volume adjuster configured to adjust a volume of the audio file according to the adjustment signal for generating the adjusted audio file.

4. The audio playing system of claim 1 , wherein the playing module is a speaker, and the speaker plays the adjusted audio file.

5. The audio playing system of claim wherein the playing module is an audio output port configured to output the adjusted audio file to an external player for being played.

6. The audio playing system of claim 1 , wherein the detecting unit is a g sensor.

7. The audio playing system of claim 1 , wherein the detecting unit is disposed near the storage medium or a main board of the electrical device.

8. The audio playing system of claim 1 , wherein the adjusting module keeps on adjusting the audio file for generating the adjusted audio file.

9. The audio playing system of claim 1 , wherein the adjusting module adjusts an initial audio source signal of the audio file to generate the adjusted audio file.

10. An audio playing method for protecting a storage medium of an electrical device, wherein the storage medium has a tolerable vibration value, and the audio playing method comprises:
(a) detecting vibration of the electrical device to generate a detection signal corresponding to the vibration;
(b) comparing the detection signal with the tolerable vibration value to generate a comparison result, and generating an adjustment signal according to the comparison result, wherein the tolerable vibration value includes an information associated with acceptable vibration values in different frequencies and the comparison result shows that the detection signal exceeds the one of the acceptable vibration values in at least one frequency;
(c) adjusting the at least one frequency of an audio file according to the adjustment signal to generate an adjusted audio file; and
(d) playing the adjusted audio file utilizing a playing module.

11. The audio playing method of claim 10 , wherein step (c) comprises:
utilizing an equalizer to adjust the at least one frequency of the audio file according to the adjustment signal to generate the adjusted audio file.

12. The audio playing method of claim 10 , Therein step (c) comprises:
adjusting a volume of the audio file according to the adjustment signal for generating the adjusted audio file.
