Passive SD150 telephone dynamic receiver for mobile phone, Φ38mm 150Ω
|Type||Dynamic receiver unit|
|Dimension||External diameter 38mm|
|Sensitivity(S.P.L)||93dB ±3dB at 1kHz 60mV with IEC 318 coupler|
|Frequency response||Refer to frequency response chart|
|Impedance||150OHM ±20% at 1 KHz|
|Magnet field intensity||Axial - dB, Radial - dB at 1KHz|
|Max. input power||Must be normal at a white noise, 50mW for 1 minute|
|Appearance||Should not exist any obstacle to be harmful to normal operation: damages, cracks, rusts, and distortions, etc.|
|Buzzer, rattle, etc.||Should not be audible at 1V sine wave between 300Hz to 3.4KHz|
|Terminal strength||Capable of withstanding 1KG load for 15 sec. without resulting in any damage or rejection|
|Load test||1mW white noise(-filter) is applied for 72 hours satisfy the tests listed on item 03,04,09 and 10|
Sensitivity difference shall be within ±3dB and should satisfy the listed on item 03,04,09 and 10, after each following test.
|Thermal cycle test||
Low temperature -40℃±3℃
Cycle: 6 hour/cycles each, and then keep 2 hours in a room.
|High temperature. test||Keep 96 hours at +70℃±3℃ and leave 6 hours in normal temperature and then check.|
|Low temperature test||Keep 96 hours at -40℃±3℃ and leave 6 hours in normal temperature and then check.|
|Humidity test||Keep 96 hours at +40℃±3℃ and relative humidity 95% and leave 3 hours in normal temperature and then check.|
|Drop test||Drop the handset mounted a unit onto a board 5mm thick 18 times from the height of 1m and them should satisfy the test listed on item 09 and 10.|
Test and measurement will be carried out under normal condition of temperature within 5℃ to 35℃, relative humidity within 45% to 85% and air pressure of 860mbar to 1060mbar.
Should uncertainly arise in data obtained from the above atmosphere, control of temperature at 20℃±2℃ and relative humidity within 60% and 70%, with air pressure remaining unchanged, to be enforced.
|Sweep freq.response||Apply test signal varying logarithmical from 100Hz to 10KHz, 2 times for 0.5 second.|
|S.P.L(Sensiticity)||Read out average figure of S.P.L meter needle|
|Freq. response curve||Apply test signal and check response curve with frequency response recorder.|
