For 1 minute, the preset pressure value can between -1~-0.5 atmospheric pressure value.Here, due to the envelope of terminal inner formation
Pressure in closed chamber body is standard atmospheric pressure, under subnormal ambient, if the air-tightness of terminal is qualified, due to the pressure in closed cavity
It is powerful in the pressure in detection case 110, evagination deformation and displacement occur for the vibrating membrane of receiver；If the air-tightness of terminal does not conform to
Lattice, because the pressure in closed cavity is more than the pressure in detection case 110, the vibrating membrane of receiver occur first indent deformation with
Displacement, and because the air-tightness of terminal is unqualified, under differential pressure action, in the rapid flow detection case 110 of air-flow in closed cavity,
And inside and outside pressing weighing apparatus is formed, the vibrating membrane of receiver recovers deformation and displacement.
After the scheduled time, terminal is taken out from detection case 110, because ambient pressure is standard atmospheric pressure, if terminal
Air-tightness it is qualified, then because the pressure in closed cavity and ambient pressure pressure are same or like, the vibrating membrane of receiver is fast
Quick-recovery is normal, now, the sounding index of the receiver of terminal is detected by voice signal detection means, can typically be led to
Cross and call " 112 " so that receiver sounding, the voice signal detection means can detect the sounding of the receiver of the terminal
Index reaches pre-set level；And if the air-tightness of terminal is unqualified, due to the pressure in closed cavity in the short time less than outer
The pressure of boundary's air pressure, the vibrating membrane of receiver concaves deformation and displacement towards closed cavity, now, passes through voice signal detection dress
Put and the sounding index of the receiver of terminal is detected, typically can be by dialing numbers " 112 " so that receiver sounding, then sound
The sounding index that sound signal supervisory instrument detects receiver is less than pre-set level.
Negative pressure air tightness detection apparatus and the detecting system of detection terminal air-tightness that the utility model embodiment is provided, pass through
Air extraction structure extracts the air in detection case so that the measured terminal in detection case is in the subnormal ambient of preset pressure value, from
And the change that can occur using the air pressure of the closed cavity of measured terminal itself under subnormal ambient, detect the gas of measured terminal
Close property, it is simple to operate, and testing cost can be reduced.
