Description
Technical field
The present invention relates to speaker technology fields, refer in particular to a kind of passive radiator speaker.
Background technology
In order to obtain better low-frequency effect, speaker can generally be increased using guide pipe and passive radiator under low frequency
Latent, principle is the resonant frequency point in speaker, and the wind speed of guide pipe and the vibration velocity of passive radiator reach maximum, sound master
It to be exported by the two, and the Oscillation Amplitude of loudspeaker is minimum at this time, not only enhances low frequency output, also protects to a certain extent
The low frequency signal that loudspeaker are subject to damages.As portable blue-tooth speaker is increasingly favored by people, speaker is generally towards small
Typeization develops, and passive radiator has shown out relative to the advantage of guide pipe, it can occupy internal appearance unlike guide pipe
Product, can be more convenient the internal structure design of speaker.Certain defect can be brought using the design of passive radiator, loudspeaker are in low frequency
Loudspeaker back side cone can push box house air to generate impact air-flow when work, and impact air-flow acts on passive radiator
Passive radiator rocking vibration can be caused if power is uneven, generated abnormal sound to pull outstanding side, especially caused low-frequency sound
It is muddy.Passive radiator waves too violent energy and cannot decay in time can also influence the vibration of Loudspeaker diaphragm in turn, influence
The clarity of loudspeaker medium-high frequency sound.

Specific implementation mode
For the ease of the understanding of those skilled in the art, the present invention is made further with reference to embodiment and attached drawing
Bright, the content that embodiment refers to not is limitation of the invention.The present invention is described in detail below in conjunction with attached drawing.
A kind of passive radiator speaker provided by the present invention, including sound box body, loud speaker and passive radiator, institute
It states loud speaker and passive radiator is respectively arranged at the inner cavity of the sound box body, set between the loud speaker and passive radiator
It is equipped with the ventilating buffering layer 6 that cushioning effect is generated to air-flow.Preferably, the ventilating buffering layer 6 is spongy layer or screen cloth.Thoroughly
The shape of gas buffer layer 6 is unlimited, can be square or round or other arbitrary shapes, be set according to the shape of speaker in practical application
It sets.Ventilating buffering layer 6 is not limited to sponge or screen cloth, can also be ventilative using other as long as can play buffer gas flow
Material substitution, the permeability of material is depending on the specific debugging situation of speaker.In the present invention, spongy layer is ventilating buffering
The optimal selection material of layer 6, spongy layer can weaken the babinet caused by standing wave and resonate, be equivalent in usually speaker and fill acoustical cotton
Effect.
Wherein, the sound box body includes Loudspeaker panel 1, speaker outline border 2 and speaker backboard 3, the Loudspeaker panel 1 and sound
Case backboard 3 is detachably connected with speaker outline border 2 respectively, and positioning is correspondingly arranged on respectively on the Loudspeaker panel 1 and speaker backboard 3
Groove (does not mark) in figure, and the both ends of the ventilating buffering layer 6 are fixed on positioning groove.In assembly, by spongy layer pair
Quasi- positioning groove is simultaneously put into pressing in place, and it is further solid to stamp glue bonding in the position that spongy layer is contacted with positioning groove
Fixed, avoiding spongy layer from deviateing original position under the promotion of air-flow influences other component.
In the present invention, the loud speaker includes the first loud speaker 4 and the second loud speaker 5, the passive radiator setting
In the centre of the first loud speaker 4 and the second loud speaker 5, and the passive radiator and the first loud speaker 4, the second loud speaker 5 it
Between be respectively arranged with ventilating buffering layer 6 described in one piece, sound box body is separated into three separate chambers by two layers of ventilating buffering layer 6
Body.As shown in figure 3, the position that two layers of spongy layer is arranged between loud speaker and passive radiator, by the inner chamber of sound box body
Body is divided into three parts, and the right and left is respectively the cavity of the first loud speaker 4 and the second loud speaker 5, and centre is passive radiator
Cavity, when the first loud speaker 4 and the vibration of the second loud speaker 5 when the generation stream pressure inside sound box body, air-flow can be in
Between cavity impact, spongy layer to air-flow buffer generate cushioning effect.Air velocity after sponge damps reduces, air-flow
Motion state is slowly to squeeze around by quick washing transition, can uniformly be pushed pressure release on passive radiator
It radiates bass, avoids some position on the violent Ground shock waves passive radiator of air-flow and rocking vibration is caused to generate abnormal sound.
It can be seen that the air-flow generated when loudspeaker vibration becomes relatively soft after spongy layer, it will not be to passive
Radiator causes fierce impact, can significantly improve the sound quality of low frequency, allows low frequency to sound cleaner, while medium, high frequency
Clarity be also correspondingly improved.
In the present invention, the passive radiator includes the first passive radiator 7 and the second passive radiator 8, described
For the setting of Loudspeaker panel 1 there are three mounting hole, first loud speaker 4, the first passive radiator 7 and the second loud speaker 5 are fixed
It is installed on Loudspeaker panel 1, speaker backboard 3 corresponds to first passive radiator 7 and opens up there are one mounting hole, second nothing
Source radiation device 8 is fixedly installed on speaker backboard 3.In vibration, two passive radiators on this speaker shake loud speaker simultaneously
It is dynamic, there is better low frequency sound quality.
In the present invention, first passive radiator, 7 and second passive radiator 8 is symmetrical arranged, and described first is passive
The centre of radiator 7 and the second passive radiator 8 is provided with the interactional air-flow retaining piece of air-flow 9 when for reducing vibration.
9 the first passive radiator of distance 7 of the air-flow retaining piece is consistent at a distance from the second passive radiator 8, can effectively reduce front and back
The air-flow generated when two passive radiator vibrations influences each other.
In the present invention, the air-flow retaining piece 9 includes barrier sheet 10, fixed ring 11 and several for connecting the resistance
The connection sheet 12 of catch 10 and fixed ring 11, the barrier sheet 10 are fixed by fixed ring 11 and Loudspeaker panel 1 or speaker backboard 3
Connection.Wherein, the air-flow retaining piece 9 is plastics retaining piece, and air-flow retaining piece 9 is integrally formed with speaker backboard 3.The fixation
Ring 11 can be pasted by glue and screw is fixed on Loudspeaker panel 1 or speaker backboard 3, can also be with Loudspeaker panel 1 or sound
3 integrated injection molding of case backboard.
The above is only present pre-ferred embodiments, is not intended to limit the present invention in any form, although
The present invention is disclosed as above with preferred embodiment, and however, it is not intended to limit the invention, any person skilled in the art,
It does not depart within the scope of technical solution of the present invention, when the technology contents using the disclosure above make a little change or are modified to equivalent change
