Piezoelectric buzzers are with us every day, and many of us may not notice them. I'll introduce you to the household appliances that use buzzers in our daily lives: such as rice cookers, washing machines, electric juicers, and air conditioners, all of which use buzzers for alerts or alarm sounds. Now, buzzers are an indispensable and important component in high-intelligence household appliances. To ensure a longer lifespan for buzzers, pay attention to the following points during use:

High welding temperatures can easily cause the buzzer housing to deform and the pins to become loose, resulting in no sound or low sound.

2. Piezoelectric buzzers may have a low or high startup voltage, leading to issues like faint or buzzing sounds during operation.

3. After storing the buzzer for a period of time, the sound may become faint, but it will return to normal after use. This situation could be due to the buzzer being affected by a humid environment; it is important to prevent moisture damage.
