Patent Application
20080091420
Many aspects of the present apparatus and the present method can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the present device. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Reference will now be made to the drawings to describe a preferred embodiment of the present apparatus and a preferred embodiment of the present method.
Referring to
The data reader 10 includes a semiconductor memory (not shown) for storing digitized and compressed encoded audio data. The data reader 10 can reproduce the compressed encoded audio data, thus yielding reproduced compressed encoded audio signals. An MP3/MP4 player, a mobile phone, or the like may act as the data reader 10 in this embodiment.
The apparatus 20 communicates with the data reader 10 via a wired or wireless connection and is configured for receiving the reproduced compressed encoded audio signals from the data reader 10. The apparatus 20 stores sound effect processing technology related programs, such as BBE, Dolby, so that the apparatus 20 can process the audio signals with one or more sound effect processing technology, thus compensating lost data in the compressed encoded audio signals. The compensated audio signals are of a higher quality, and are converted into audible sound by the earphone 30.

The power supply 200 is used for providing power for all components among the apparatus 20. The power supply 200 can be a dry battery or a storage battery. The input module 202 is for receiving the reproduced audio signals from the data reader 10. The ADC 204 is for converting the reproduced audio signal from an analog format into a digital format. The processor 206 is for processing the digital audio signal with the sound effect processing technology, such as the BBE technology. The DAC 208 is for converting the digital audio signal processed by the processor 206 into an analog audio signal. The volume adjusting module 210 is for adjusting a volume of the analog audio signal from the DAC 208. The amplifier 212 is for amplifying the analog audio signal from the volume adjusting module. The output module 214 is for outputting the analog audio signal from the volume adjusting module to the earphone 30. The display module 216 is for displaying some data of the audio signal, such as names of songs, volume.
The volume adjusting module 210 includes a collecting unit 220, an identifying unit 222, a controller 224, and a volume adjuster 226. The collecting unit 220 is for collecting sound waves of various environments where the portable audio reproducing apparatus is located. The identifying unit 222 is for identifying a volume of the sound waves. The controller 224 is for generating a volume adjusting signal based on the volume of the sound waves, and using the volume adjusting signal to control the volume adjuster 226 to adjust volume of the analog audio signal.
Therefore, the portable audio reproducing apparatus can output the audible sound with optimal volume wherever the portable audio reproducing apparatus is located.
