--professionally manufactures and sells all kinds of buzzers. We have
two production lines: piezo buzzer and magnetic buzzer, both include the
self drive type, external drive type and SMD type.
(Magnetic Buzzer, Transducer, Mechancial Buzzer, Beeper,
Piezo Element, Buzzer, Transducer, Piezo Siren, Alarm.)
There are over one thousand specifications now, the complete dimensions
for you to choose, we can modify the length of the pins and the wires,
or even customize for your unique project.
Rated Voltage: A piezo buzzer is driven
by square waves (V p-p).
Operating Voltage: For normal operating. But it is not
guaranteed to make the minimum SPL under the rated voltage.
Consumption Current: The current is stably consumed under
the regular operation. However, it normally takes three times of current
at the moment of starting to work.
Capacitance: A piezo buzzer can make higher SPL with
higher capacitance, but it consumes more electricity.
Sound Output: The sound output is measured by decibel
meter. Applying rated voltage and square waves, and the distance of 10
Rated Frequency: A buzzer can make sound on any frequencies,
but we suggest that the highest and the most stable SPL comes from the
Operating Temp.: Keep working well between -30℃ and +70℃.
How to choose:
Driving methods: AZ-xxxxS-x series with built drive circuit
will be the best choice when we cannot provide frequency signal to a buzzer,
it only needs direct current. Besides, there are different tone nature
for you to choose, such as continuous, fast pulse, and slow pulse.
Dimension: Dimension affects frequency, small size result in high frequency.
Voltage: Driven by square waves (V p-p), the higher voltage results in
the higher SPL.
Pin Pitch: The numerous spec. for the piezo buzzers lead to the difficulty
in finding a spec. in facsimile, therefore we suggest that you can firstly
choose a spec. with the same pitch and similar frequency.
