蜂鸣器有有源和无源之分，此处用的是无源蜂鸣器。信号驱动有IO模拟PWM和硬件PWM，鉴于IO模拟PWM太占用中断资源，严重影响MCU效率，故采用硬件产生PWM。本帖主要介绍蜂鸣器PWM的两种使用方式：
1：将播放程序放到主函数main中的while(1)来播放曲目。此种方式，仅适合任务量轻，时序要求不高的系统，一旦单片机处理的任务太多，而while(1)中的程序得不到及时执行，就会出现曲目变形，节奏不符。不过也可以用RTOS操作系统来弥补缺憾，在此不介绍！
2：将播放的程序放到定时器中断中。执行效率高，耗时极少，不影响其他任务
/*说明
  硬件平台--STM32F103VET6-(可适用STM32F103VCT6)
  采用标准库

  功能：蜂鸣器信号采用PWM方式，由NPN三极管驱动电磁蜂鸣器，播放特定曲目
  引脚：PB1----TIM3CH4
