Measuring Methods
1) Resonant frequency / Resonant impedance
The piezo electric diaphragm should be clamped at a node point (as shown in the following figure) to be free from any
mechanical stress. Measure its resonant frequency and resonant impedance by using a vector impedance analyzer or
equivalent.
When the input frequency is swept within 100 Hz to 3 KHz, the resonant frequency is defined as the frequency where
the impedance shows minimum value. This impedance should be the resonant impedance.
2) Static capacitance
The electrostatic capacitance should be measured at 120 Hz by using an L.C.R. meter (ex. HP4194A(H.P.)) or
equivalent. The part should be clamped in the same way as the measurement or resonant frequency / resonant
impedance mentioned above.

Test Condition
Evaluation Standard
Solderability
(Connector excepted)
Stripped wires of lead wires are immersed in
rosin for 5 seconds and then immersed in
solder bath of 270 ±5°C for 3 ±0.5 seconds.
The horizontal force of 3.0N (0.306kg) should
be applied to the double lead wire for 30 sec.
The diaphragm should be measured after
applying a vibration amplitude of 1.5 mm with
90% min. of the stripped wires
will be wet with solder. (Except
the edge of the terminal)
No damage or cutting off.
Lead Wire Pull Strength
Vibration
The value of the resonant
frequency should be ±10% of the
10 to 55 Hz band of vibration frequency to each initial measurements.
of the 3 perpendicular directions for 2 hours.
Electrostatic capacitance should
be ±20% compared with the initial
measurement. The SPL should
be within ±10dB compared
with the initial measurement.
