Title:
AN ACOUSTIC STRUCTURE WITH A PASSIVE DIAPHRAGM UNIT
Document Type and Number:
WIPO Patent Application WO/2017/199177
Kind Code:
A1
Abstract:
This invention provides an acoustic structure with a passive diaphragm unit comprising: a housing, a speaker unit, at least one passive diaphragm unit and a fairing. The housing, as mentioned earlier, has a closely connected aperture with the speaker unit and the passive diaphragm unit, the cavity inside the housing mentioned above forms a resonator of the speaker unit and the passive diaphragm unit. The fairing above is arranged inside the resonator and is arranged in a coaxial relation with the passive diaphragm unit; there is a through-hole connected to the passive diaphragm unit at the axis of the fairing, the remaining parts separate the passive diaphragm unit from the resonator. This invention provides an acoustic structure that has a passive diaphragm unit, wherein the acoustic radiation wave of the passive diaphragm unit is uniformly symmetrical, and the vibration is relatively uniform.
