折叠编辑本段简介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,因为压电效应,蜂鸣片就会产生机械变形而发出声响。压电材料有多种,用在蜂鸣片上的压电材料通常是高压极化后的压电陶瓷片。折叠编辑本段外观结构压电式蜂鸣器通常呈圆形,由压电陶瓷片、引线和共鸣腔组成。而中间的压电陶瓷片又由金属镀层、陶瓷片、胶水、金属片构成。常见的压电式蜂鸣器的形状及电路符号如右图所示:从电学角度来看,压电陶瓷可以简化为一个电感和一个电容的串联模型。折叠编辑本段分类除上图所示的两根电极的全电极型压电蜂鸣片之外,还有一种三个电极的反馈电极型压电蜂鸣片。通常全电极型蜂鸣片驱动电路简单,但发出的声音较小;反馈电极型驱动电路相对复杂,但发出的声音较大。以回授方式区分,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。折叠编辑本段特点及应用压电式蜂鸣器具有体积小、灵敏度高、耗电省、可靠性好,造价低廉的特点和良好的频率特性。

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方波驱动的蜂鸣器发出的声音效果更好,没有杂音,从而改善蜂鸣器音质。2.第二开关管q2、第三开关q3会同步振荡频率改变振荡电路,从而引起蜂鸣器两端更大的变化,增加了蜂鸣器两端的压差,进而增强了蜂鸣器的音量。3.上述蜂鸣器驱动电路包括电源控制电路10,电源控制电路10根据mcu产生简单的高低电平控制所述蜂鸣器驱动电路是否对gnd形成回路从而控制蜂鸣器的工作状态,确保了整个电路的可控性和有效性,整个控制过程可靠且迅速。静安区AD16系列蜂鸣器代理品牌
