DC type micro magnetic buzzer with oscillator circuit Φ9.6*5mm
Description:
The electromagnetic buzzer generally consists of a plastic housing
with a metal diaphragm that is flexed by an electro- magnet. The
main benefit of this design is the ability to obtain low
frequencies in a small package. Drawbacks include mechanical wear,
electrical noise, lower sound output, and large power consumption.
Precautions for use:
• Do not apply DC bias to the buzzer; otherwise insulation
resistance may become low and affect the performance.
• Do not supply any voltage higher than applicable to the buzzer.
• Do not use the buzzer outdoors. It is designed for indoor use. If
the buzzer has to be used outdoors, provide it with waterproofing
measures; it will not operate normally if subjected to moisture.
• Do not wash the buzzer with solvent or allow gas to enter it
while washing; any solvent that enters it may stay inside a long
time and damage it.
• Do not apply any mechanical force to the buzzer; otherwise the
case may deform and result in improper operation.
• Do not place any shielding material or the like just in front of
the sound release hole of the buzzer; otherwise the sound pressure
may vary and result in unstable buzzer operation. Make sure that
the buzzer is not affected by a standing wave or the like.
• Be sure to solder the buzzer terminal at 350℃ max.(80W
max.)(soldering iron trip) within 5 seconds using a solder
containing silver.
• Avoid using the buzzer for a long time where any corrosive gas
(H2S, etc.) exists; otherwise the parts or sound generator may
corroded and result in improper operation.
• Be careful not to drop the buzzer.
