The invention provides a path information getting method and a path calculating node (PCE). From the original PCE, the shortest paths between the original node and the outlet border node of a self-charged region are calculated one by one, the calculating result is sent to a next jump PCE, the process goes on until a converging PCE is reached. At the same time, from a target PCE, the shortest paths between the target node and the inlet border node of the self-charged region are calculated one by one, the calculating result is sent to the proceeding jump PCE, the process goes on until the converging PCE is reached. The converging receives the calculated results sent by the proceeding jump and the next jump and then calculates the shortest path between the original node and the target node and sends the shortest path to the original PCE. That is to say, the PCE on the two sides of the converging PCE calculates the shortest path and transmits the calculated result at the same time; and the calculated result is transmitted to the original PCE by the converging PCE. So the total time consumed by getting the shortest path is shortened.

A speaker leak test system which quickly tests if a speaker enclosure is sealed properly. The speaker leak test system tests for air leaks in the speaker enclosure, which air leaks degrade the acoustic performance of the speaker. A vacuum (or pressure) source is connected through a vacuum hose to the speaker enclosure and vacuum is drawn. After a test vacuum level is reached, the mass air flow through the vacuum hose is measured. If the mass air flow does not exceed a pre-determined speaker dependent threshold for the speaker under test, the speaker is declared to be leak free. A bypass solenoid may reside in parallel with a mass air flow sensor to reach test vacuum quickly. This speaker leak test system is intended to be used in a prototyping and production environment and tests the speaker enclosure for leaks both quickly (e.g., less than five seconds) and accurately.
