折腾了:

【整理】音频功放芯片:三星 T9895 音频功放芯片

后来参考:

两款爆品迷你智能音箱拆解对比:天猫精灵方糖、小爱mini-天猫精灵,方糖,小爱,小爱mini,迷你,智能音箱,拆解 ——快科技(原驱动之家)–全球最新科技资讯专业发布平台

的解释:

NXP TFA9895 D类音频放大器。右侧为升压电感,在低压供电时提供足够的输出功率。

-》看来是我搞错了。

再去找找:

Speaker boost IC aims to improve sound quality in smartphones | Smart2.0

NXP has extended its range of speaker driver ICs with the TFA9895 – its second-generation speaker boost solution – which improves the sound quality of handsets and tablets via a new multi-band compression feature which enhances the way music and voice sound, even at louder speaker volumes.

The multi-band processing feature in the TFA9895 improves audio quality at louder speaker volumes via more stable high-gain audio imaging. The TFA9895 also adds a high-frequency noise gate that improves the sound of poor-quality audio signals. Like its predecessor, the TFA9887, the TFA9895 offers a completely integrated small speaker driver, including integrated processing and an on-board 5-V DC/DC converter, as well as complete protection against speaker failure. Both ICs can deliver 4W of peak power into a 4-Ohm speaker that is conventionally limited to 0.5W.

还是搜不到原始芯片的part number的

(也可能是由于文字看不清导致的)

不过倒是从:
