Porting

摘要

A ported electroacoustical device that uses the action of the port to provide cooling airflow across a heat producing device. The device includes a loudspeaker enclosure including a first acoustic port, an acoustic driver, mounted in the loudspeaker enclosure. The device also includes a heat producing device. The acoustic driver and the acoustic port are constructed and arranged to coact to provide a cooling, substantially unidirectional airflow across the heat producing device, thereby transferring heat from the heat producing device.

主权项

1. An electroacoustical device, comprising:
an acoustical enclosure having an enclosure interior and an enclosure exterior; a port tube having a port tube interior, acoustically coupling the enclosure interior and the enclosure exterior, having a first end adjacent the enclosure interior and a second end adjacent the enclosure exterior; the port tube comprising a vent intermediate the port tube first end and the port tube second end acoustically coupling the port tube interior with a first close ended resonant tube and a second close ended resonant tube; and
acoustic damping material in the vent.
