摘要
介绍了具有较强通用性的语音告警系统。系统通过单片机ATMEGA16控制语音芯片ISD1790,实现了在不同情况下提供不同的语音提示告警,且提示语音可以自行录入。最后通过D类音频功率放大器TPA3101D2,实现了高音质大音量语音输出。
This paper introduced a common audio module for instruments to warn the user. In this system, the singleehip ATMEGA16 is taken to control the ISD1790 to display different records in different conditions, which are recorded in advance. In the end, the class-D audio amplifier TPA3101D2 is adopted to output a clear good and loud voice.
