    Abstract: Audio amplification may be improved by controlling an audio amplifier based on the audio signal being amplified. For example, when the audio signal level increases or decreases, a boost voltage provided to an audio amplifier by a boost converter may also be increased or decreased. In another example, when the audio signal level decrease below a certain level, the audio amplifier may be switched from amplifying the audio signal with a boost converter input to amplifying the audio signal with a low voltage input. Control of the audio amplifier may be implemented in a digital boost converter controller coupled to the boost converter and/or the audio amplifier.

    Abstract translation: 可以通过基于被放大的音频信号控制音频放大器来改善音频放大。 例如,当音频信号电平增加或减小时,升压转换器提供给音频放大器的升压电压也可以增加或减小。 在另一示例中,当音频信号电平降低到低于某一水平时,可以利用升压转换器输入将音频放大器切换成放大音频信号,以便以低电压输入放大音频信号。 可以在耦合到升压转换器和/或音频放大器的数字升压转换器控制器中实现音频放大器的控制。
