       电磁式蜂鸣器，具体涉及一种内置低电压启动驱动芯片的有源蜂鸣器。背景技术：现有的电磁式有源蜂鸣器，大部分仍然使用三极管构成驱动电路的双组电磁线圈结构，存在成本高和可靠性低等缺点；也有采用芯片作为驱动电路的单组电磁线圈结构，但存在如启动电压高、可靠性低等缺点。技术实现要素：本发明的目的是为了解决集成电路芯片作为有源蜂鸣器驱动电路时，启动电压高、可靠性低等缺点。为了解决所述问题，本发明提供一种内置低电压启动驱动芯片的蜂鸣器，包括集成电路驱动芯片、电容、单组电磁线圈、线路板、支架、磁环、振动片、正极针脚、负极针脚、壳体、密封胶，其中所述集成电路驱动芯片、电容、正极针脚、负极针脚焊接在线路板上，集成电路驱动芯片电源连接电容一端，电容另一端连接负极针脚，集成电路驱动芯片地线连接负极针脚，单组电磁线圈一端连接正极针脚，单组电磁线圈另一端连接集成电路驱动芯片的输出端，所述集成电路驱动芯片内部包含控制电路、pmos管、振荡电路、整流电路、驱动电路。当蜂鸣器正极针脚接直流正极，当蜂鸣器负极针脚接直流负极时，直流正极通过单组电磁线圈和pmos管对电容充电，集成电路驱动芯片内部振荡电路工作。 按键按下、开始工作、工作结束或是故障等等。这里对单片机在蜂鸣器驱动上的应用作一下描述。主营AD16系列蜂鸣器厂家供应

接通电源后1.5~15V直流工作电压多谐振荡器起振输出1.5~2.5kHZ的音频信号，阻抗匹配器推动压电蜂鸣片发声。主营AD16系列蜂鸣器厂家供应
