Sound Components (Buzzer)Piezoelectric Buzzers: Precautions When Correcting Products That Have Been Soldered in a Tilted State

If the pins touch two locations on the piezoelectric diaphragm, a short may occur, preventing any sound from being emitted.

The image below depicts the piezoelectric buzzer's structure.

Due to the structure, if a large enough force is applied to the external pins, they may be pushed into the product. This is liable to cause a failure.

In order to prevent a defect due to the pins being pushed in, be careful not to apply a force exceeding the value shown below, for each product. Note that if the temperature of the product is high, there is a possibility of a defect occurring even under a force that is weaker than the following value.
