Embodiment 1

[0048] Such as figure 1 As shown, the audio playback device provided by the embodiment of the present invention includes a playback unit, a storage unit, a control unit, and a signal scaling unit, wherein:

[0049] The storage unit is used for pre-storing at least two characteristic values ​​of volume modes with different sound volume lines;

[0050] The control unit is used to read the feature value in the storage unit, and according to the feature value, the volume mode corresponding to the feature value, and the sound volume line corresponding to the volume mode, the signal scaling unit performs scaling processing on the audio signal and sends it to the playback unit to play.

[0051] Since the storage unit provided by the embodiment of the present invention has at least two different volume modes pre-stored, and the sound volume lines of different volume modes are different, multiple volume modes can be designed according to user preferences and needs, so that different u...

Embodiment 2

[0066] Such as Figure 4 and Figure 5 As shown, this embodiment is basically the same as Embodiment 1, and the difference is that the audio playback device provided by this embodiment also includes a mapping unit, and the mapping unit is used to prestore or record the actual volume of the same, different sound modes Correspondence between eigenvalues;

[0067] The control unit is used to read from the storage unit the desired value corresponding to the characteristic value of the sound mode before switching according to the mode switching instruction input by the user and the corresponding relationship between the characteristic values ​​of different sound modes pre-stored or recorded by the mapping unit. The characteristic value of the sound mode changed.

[0068] In this embodiment, according to the corresponding relationship between the mode switching instruction input by the user and the characteristic values ​​of different sound modes, the control unit reads the corres...
