Fig. 4 to Fig. 7 is referred to, now the embodiment of audio device provided by the invention is illustrated.Audio device, including
Babinet, sounding component and the sounding chamber 11 in babinet, sounding component are located in the sounding chamber 11.Babinet is additionally provided with level-one
It leads phase structure 3 and the two level for nonlinear type air guide leads phase structure 21, level-one leads phase structure 3 for two level to be led phase structure 21
It is connected with sounding chamber 11.Two level leads the tool of phase structure 21 there are two opening, i.e., and the of the first opening 212 and opposite first open 212
Two openings 211, for being in communication with the outside, the second opening 211 is connected the first opening 212 for leading phase structure 3 with level-one.
Level-one lead phase structure 3 and two level to lead phase structure 21 can be the leading notes such as traditional phase guide tube or channel, air guide knot
Structure.Two level lead phase structure 21 be carry out nonlinear type air guide lead phase structure, phase structure i.e. the is led in so-called nonlinear type air guide
It (may be broken line or arc that the communication path of one opening 212 and the second opening 211 in two level leads phase structure 21, which is non-rectilinear,
Communication path), sound wave is non-straightline propagation in two level leads phase structure 21.
It is to be arranged along substantive vertical direction (direction for being substantially perpendicular to tank floor), that is, make that level-one, which leads phase structure 3,
Level-one is led the sound wave in phase structure 3 and is propagated along substantive vertical direction, and two level leads phase structure 21 and leads 3 essence of phase structure with level-one and hangs down
Straight setting, that is to say, that it is in the horizontal plane of essence or to be parallel in the plane in substantial level face and set that two level, which leads phase structure 21,
The nonlinear type set leads phase structure, and two level leads the sound wave in phase structure 21 in substantial level face or is parallel to substantial level face
Plane in propagated.First opening 212 is divided into the both sides of babinet, i.e., the first opening 212 and sounding group with sounding component
Location interval 180 degree setting of the part on babinet.Usually, sounding component is located at the front side of babinet, towards user, the first opening
212 are located at the rear side of babinet, backwards to user.
In this way, when the normal use of audio device provided in an embodiment of the present invention (generating assembly towards user), sound wave
Propagation in leading phase structure is to first pass through the level-one that vertical direction is arranged to lead phase structure 3, first by sound in level-one leads phase structure 3
Wave phase is adjusted to vertical direction, is parallel to the phase of metope, is equivalent to decrease (adjustment) sound wave, is so equivalent to covert
The influence of metope and metope distance factor to audio device provided in an embodiment of the present invention is reduced, metope environment is influenced to reduce；
When sound wave leads phase structure 21 by two level, and acoustic phase is adjusted to the parallel bottom of box (parallel water plane), and because
It is that nonlinear type leads phase structure that two level, which leads phase structure 21, makes to lead phase sound wave and are nonlinearly travels to first from the second opening 211 and opens
At mouthfuls 212, sound wave can blaze abroad from the first opening 212 with certain angle again, this also makes two level lead the sound of phase structure 21
Wave, in the relationship (lead phase sound wave non-90 degree and be incident on metope) of (vertical) incidence of non-90 degree, further subtracts with the metope being vertically arranged
The influence to leading phase sound wave of few metope and metope distance.
Audio device provided in an embodiment of the present invention leads phase structure by adding the level-one being vertically arranged and leads phase with level-one
Structure vertical is arranged and the two level of nonlinear type air guide leads phase structure, and decrease leads phase sound wave, and sound wave is made to hang down in non-with metope
Straight incident relationship, to make audio device provided in an embodiment of the present invention combine leading phase, after lead phase acoustic structure and ABR
The advantages of passive vibrating diaphragm leads phase sound equipment reduces audio by metope and from wall while reservation guide type sound equipment low-frequency effect is good
The influence of face distance factor；In the varying environment of distance from the wall distance, the music of audio device provided in an embodiment of the present invention
Effect is almost consistent.
