【经验】音频驱动芯片SGM4890出现POP音和语音中断问题的分析与解决
某客户设计一款扫地机器人,同时具备语音播报功能,音频驱动芯片采用国产圣邦微SGM4890,但是在实际测试中发现输出会有POP音,同时部分语音有中断现象,本文主要分析SGM4890 POP音产生的原因,同时提供解决办法。客户设计原理图如下:
客户描述故障现象如下:
语音播报初始内容丢失。
语音播报前会有CLICK-POP音。
故障原因分析:
测试Pin3 Bypass脚电压C357为4.7uF),和Vo启动电压波形如下:
从波形可以看出,SGM4890的Bypass电压的建立时间为680ms,而语音播报会在芯片使能后320ms后输出,因此会造成前级语音丢失现象,减小启动电容C357,减小芯片启动时间,可以解决语音丢失问题,实际在C357设置为1uF时,启动时间为110ms,没有语音丢失现象。在电容更换为1uF之后 测试电容对POP的抑制现象。
如图所示,如果Vbias跳变的缓慢,POP冲击就会减小,此时的冲击脉宽就会变宽,幅度有所下降,这样POP音就会变小,低于人耳接收频率。
总体结论是:减小启动电容同时可以解决POP音和输出音频丢失问题。
