本实用新型涉及蜂鸣器技术领域,特别涉及一种便于安装的压电式蜂鸣器。背景技术:蜂鸣器是一种一体化结构的电子讯响器,采用直流电压供电,广泛应用于计算机、打印机、复印机、报警器、电子玩具、汽车电子设备、电话机、定时器等电子产品中作发声器件。蜂鸣器主要分为压电式蜂鸣器和电磁式蜂鸣器两种类型,压电式蜂鸣器是一种电声转换器件,将压电材料粘贴在金属片上,当压电材料和金属片两端施加上一个电压后,因为逆压电效应,蜂鸣片就会产生机械变形而发出声响,压电式蜂鸣器大致分为回授式蜂鸣片(自激式)与无回授式蜂鸣片(外激式)两种。当回授式蜂鸣片搭配正回授振荡电路会产生一个与共振腔频率相同的单音;而无回授式蜂鸣片则可以搭配外部振荡电路,选择任意频率发出声音。然而,目前现有的压电式蜂鸣器大多装配复杂,安装较为繁琐,效率低,不方便安装及后期维护。徐州主营AD16系列蜂鸣器厂家
振荡回路30会根据第二开关管q2和第三开关管q3的状态变化而改变振荡回路,振荡回路改变时,电容c1两端的压差由2*vcc变为4*vcc,增加了蜂鸣器两端的压差变化。本发明的有益效果:1.上述蜂鸣器驱动电路由电感l1、第二点l2和电容c1组成的振荡回路驱动蜂鸣器,同时由第三电感l3和第二开关管q2、第三开关q3组成的振荡控制电路对所述振荡回路进行稳定的闭环控制,使振荡回路工作时的振荡波形稳定,在蜂鸣器两端产生标准正弦波,驱动蜂鸣器发声,无需mcu输出pwm来驱动蜂鸣器,从而减少mcu的io口占用,节省了主控mcu的资源;此外,标准正弦波作用于蜂鸣器两端,蜂鸣器发出的声音比由pwm方波驱动...
