Mechanical Characteristics
Item
Solderability
Test Condition
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 pull force should be applied to double lead
wire:
Horizontal 3.0N (0.306kg) for 30 seconds
Vertical 2.0N (0.204kg) for 30 seconds
The speaker should be measured after applying
a vibration amplitude of 1.5 mm with 10 to
55 Hz band of vibration frequency to each of
the 3 perpendicular directions for 2 hours.
The part will be dropped, contained inside a
normal box, from a height of 75 cm onto a 40
mm thick wooden board 10 times.
Evaluation Standard
90% min. stripped wires will be
wet with solder.
(Connector Excepted)
(Except the edge of the terminal.)
Lead Wire Pull Strength
Vibration
No damage or cutting off.
No obstacle will be harmful to
normal operation; damage,
cracks, rust, and distortions.
Should not be audible at 1.55 V
sine wave between Fo ~ 20 KHz.

Test Condition
Evaluation Standard
High temp. test
After being placed in a chamber at 85°C for
8 hours.
Low temp. test
Humidity test
After being placed in a chamber at -20°C for
96 hours.
After being placed in a chamber at +60°C and
90% relative humidity for 240 hours.
The part shall be subjected to 5 cycles. One
cycle will consist of:
The speaker will be measured
after being placed at +25°C for 6
hours. No obstacle will be harm
ful to normal operation; damage,
cracks, rust, and distortions.
Should not be audible at 1.55 V
sine wave between Fo ~ 20 KHz.
The SPL should be within ±3dB
when compared to the initial
measurements.
