Sound Components (Buzzer)Piezoelectric Buzzers: Precautions in the Event the Case and Rear Cover Come off after Mounting

Deformation and mis-positioning of the pins or the vibration plate may result in unstable sound or prevent the generation of any sound at all.

After mounting the piezoelectric buzzer on the printed circuit board or the set, if you apply a large force exceeding the fitting force or the adhesive force to the side of the product, the casing or the vibration plate will separate from the rear cover.

If you re-assembled the casing and the piezoelectric diaphragms, the exterior may in some cases appear to have returned to the condition prior to the separation of these parts.
