The value of oscillation
The buzzer will be measured after applying
frequency/current consumption
a vibration amplitude of 1.5 mm with 10 to
should be ±10% of the initial
55 Hz band of vibration frequency to each of
measurements. The SPL should
the 3 perpendicular directions for 2 hours.
The part will be dropped from a height of 75 cm be within ±10dB compared with
the initial measurement.
onto a 40 mm thick wooden board 3 times in
3 axis (X, Y, Z) for a total of 9 drops.
