The preferred embodiment and the detailed description are as follows. [Embodiment] The following will refer to the relevant drawings. A volume range adjustment system and method in accordance with a preferred embodiment of the present invention will be described with the same reference numerals. Please refer to the first figure, which is a block diagram of the volume range adjustment system of the present invention, and is applicable to a playback device such as a multimedia player. The towel, volume range adjustment system 11 includes a recording unit 12, a sampling unit 13, a processing unit 14, and a sound source output unit 15. The recording unit 12 has at least one music file 121. The sampling unit it 13 performs a sampling operation according to the music slot #121 to generate a plurality of sample values m. The processing unit 14 calculates an average value between the volume sample values 131 and the same as the fresh value 141, the canister-output volume range. The sound source output single το15 touches the volume range of the touch sound case 121. In the case of the towel, when the average value is greater than the standard value 141, the button unit 14 will lower the volume range, and when the average value of 1294094 is less than the standard value 141, the processing unit 14 will increase the output volume range. The processing unit 14 also records the output volume range to the recording unit 12 for use in playing the music file 121 again. In addition, the music file can be Mp3 (MpEG岚 ratio = yer~3) music format, wma (Windows Media Audio) music format, 0GG 曰 格式 format or ASF (Audio Steaming format) music format. Wherein, the sampling unit selects a plurality of sampling points according to the distribution position of the main melody on the music file 121, and generates corresponding plurality of volume sampling values according to the sampling points. The number of sampling points depends on the execution ability of the playback device. When the playback device is executed, the stronger the b-force, the more the number of sampling points, that is, the more accurate the average value of the processing unit is. Please refer to the second figure, which is a volume coordinate diagram of a music file according to an embodiment of the present invention, taking a small music file as an example. The volume coordinate map 21 has a horizontal axis 22, a vertical axis 23, and a plurality of sampling points 24 (represented by squares). The axis 22 represents the frequency of each music signal in the music file, and the vertical axis 23 represents the corresponding volume. The sampling unit corresponds to the vertical axis 23 according to the sampling points 24 to generate a corresponding plurality of volume sampling values. Taking the sampling point 241 and the sampling point 242 as an example, the sampling value 231 of the sampling point 241 is called l〇dB.
