EMARK：

In order to keep the forerunner position of the product, our company carry out the layout

upgrading and color adjustment. After the technique renewing, further notice will be given. If you

have any doubt, please contact with our marketing department .

The color difference is according to different batch purchasing, while the functions of product

will not be affected. So it does not regards as acceptance standard.

5.2 REQUEST:

The tolerance of sensitivity is within +/- 3dB to standard microphone.

5.3.1 Measure the microphones under standard operating condition.

5.3.2 Put the microphone and standard microphone face to the sound source（speaker）, the

distance between sound sourcet and microphone & standard microphone is 50cm. And keep the

center distance 5cm between them to ensure that the change of sound pressure should be kept within

+/- 1dB.

5.3.3 Keep the sound source pressure within +/- 1dB from speaker（Measured by standard

microphone）

5.3.4 The sensitivity of microphone can obtain its output voltage when sound source kept

within 1000Hz & 1Pa.

6. RELIABILITY TEST

All tests are carried out on the same test batch according to the listing order.

The sensitivity should be within ±3dB from initial sensitivity after 3 hours recovering on the

After exposure at 60℃ for 200 hours, ,the sensitivity should be within ±3dB from the initial value.

After exposure at –25℃ for 200 hours the sensitivity should be within ±3dB from the initial value.

After exposure at 40℃ and 90~95% relative humidity for 200 hours, the

sensitivity should be within ±3dB from the initial sensitivity.

7. REGARDING THE SOLDERING OPERATION

THE STORAGE, TRANSPORTATION AND USING GUIDE OF CONDENCER MICROPHONE

7.1Testing Condition

In Normal Weather

Environment Temperature : 5 ~ +35°C

Relative Humidity : 45 ~ 85%

Air Pressure : 86 ~ 106Kpa

In Arbitrate Weather

Environment Temperature : 20 +/- 2°C

Relative Humidity : 60 ~ 70%

Air Pressure : 86 ~ 106Kpa

8. TEMPERATURE CONDITONS

The full packed Mic. should be stored at warehouse in –20 ~ 70°C, and the relative humidity

should not be more than 90%. The warehouse must keep constant temperature, without acid or any

other poisonous gas, and no influence from strong magnetic field.

Operating temperature: -20℃~+70℃

9. CONCEPT OF UNIT

The difference between the concept of unit “Pascal” and that of the unit “μbar” can be

explained as follows. In order to calibrate the sensitivity of ECMs the sensitivity is manifested

differently according to the unit “Pascal” or “μbar”.

That is, the sensitivity will be increased by 20 dB when using of the unit “Pascal”.

Example:-60dB(0dB=1V/μbar)=-40dB(0dB=1V/Pa)
