Double-walled unit |
| abstract |
Double-walled unit. The invention relates to a unit comprising a double wall and an active control system. The double wall defines a cavity. The active control system comprises one or more loudspeakers which are arranged in the cavity. Each of the one or more loudspeakers has a membrane. At least one loudspeaker is arranged in such a manner that its membrane is substantially parallel with the walls of the double wall and the loudspeaker has a thickness which is strictly less than the thickness of the cavity. The invention constitutes an improved unit comprising a double wall and an active control system. |
