用于播放音频信号的设备和方法
摘要：
一种用于控制音频信号(SA)播放的设备和方法，其中该设备通过储能设备(2)运行，包括下列步骤：—使正常模式(MN)无效并激活节能模式(MS)，其中储能设备（2）为播放音频信号（SA）的功率消耗在节能模式(MS)相比于正常模式（MN）减少，—在节能模式(MS)中减少音频信号(SA)的频谱(X(fSA))的低音频率分量(B)，并输出具有降低低音频率分量(B)的音频信号(SA)，—确定储能设备(2)的电荷状态(C)，以及—基于储能设备(2)的电荷状态(C)的降低控制低音频率分量(B)的降低。
摘要（英）：

Device and method for controlling reproduction of an audio signal (S A ), wherein the device is operated by means of an energy storage device (2), characterized in that - a normal mode (M N ) is deactivated and an energy saving mode (M S ) is activated, wherein an power consumption from the energy storage device (2) for reproduction of the audio signal (S A ) is reduced in the energy saving mode (M S ) as compared to the normal mode (M N ), - in the energy saving mode (M S ) a bass frequency component (B) of a frequency spectrum (X(f SA )) of the audio signal (S A ) is reduced and the audio signal (S A ) is output with reduced bass frequency component (B), - a charge state (C) of the energy storage device (2) is ascertained, and - the reduction in the bass frequency component (B) is controlled based on a decrease in the charge state (C) of the energy storage device (2).
