Description
Technical field
The present invention relates to acoustic product technical field, more particularly to a kind of loudspeaker bugle.
Background technology
In traditional speaker system design, it is frequently encountered using a high frequency driver and a low frequency cell group
Into the full-range cabinet of one two frequency dividing, high frequency driver can carry a bugle to coordinate with low frequency cell, so that high-frequency drive
Think highly of the sound wave put and project and use space.
Sound wave reflection and sound wave interference phenomenon are had according to acoustic theory sound wave, high frequency driver vibrating diaphragm does piston before and after
During motion, by bugle throat, outwards radiation forms sound to resulting sound wave.However, not all sound wave is all direct
To external diffusion, in the ear that acoustic wave segment just will deliver to listener on the reflecting surface of bugle after crossed reflex.Traditional
In bugle, sound wave will first be reflected to another side and be re-reflected into listener.Because these sound waves were produced in the same time
But hear in different time, the sound wave that this process is produced with vibrating diaphragm not only again but also generates sound wave interference phenomenon, and this is just
Define standing wave distortion.And phase plug rapidly can launch secondary counter ejected wave, lag time is reduced.
Phase potential energy plug enough effectively improves Frequency Response, prevents standing wave and intermodulation distortion so that off-axis frequency response diffusion property
With more smooth to axle frequency response diffusion property, it is to avoid the off-axis frequency response peak valley phenomenon that Jing often occurs in bugle.That is, phase place
The presence of plug, can effectively improve the phase place performance of loudspeaker, the name origin of this namely phase plug.
At present, general " eight " shape of bugle that high frequency driver is carried, bugle shell is with the joining place of high frequency driver
One circular hole, commonly referred to as bugle trunnion, bugle shell is usually directly by certain linear to external expansion from bugle trunnion
To bugle shell big opening (face) place.The typically no phase plug of bugle that on the market high-pitched driver is used, or be only
Using easy sub warhead phase plug, and sub warhead phase plug only even circumferential type " eight " shape bugle shell is had it is certain
Positive effect, when bugle shell is other shape, far can not just meet needs.
In addition, in prior art, the upper limiting frequency of the bugle of high frequency driver is only 16.5kHz, with high-quality requirement
The upper limiting frequency of 20kHz requires there be a certain distance；The lower frequency limit of the bugle of high frequency driver can not meet needs.
The deficiency of the bugle of the high frequency driver used according to above existing market be necessary invention performance it is more excellent number
Angle, to manufacture more excellent speaker system.
The content of the invention
In order to solve above technical problem, the present invention provides one kind and can lift bugle upper limiting frequency, expands lower frequency limit simultaneously
Reduce the loudspeaker bugle of sonic transmissions distortion.
In order to realize the technique effect of the present invention, employ the following technical solutions and be achieved：
A kind of loudspeaker bugle, including a horn-like shell, the small end connection mounting seat of the shell, big end is face
Disk, the shell includes the trunnion being connected with mounting seat, and several manifolds, the manifold and trunnion are fixed with the trunnion
Two ports be connected.
Used as further improvement, the bugle also includes the air deflector for the sound wave of high frequency driver to be shunted.
Certainly, when high frequency driver connected with outer casing, high frequency driver is close to the small end of shell.Shell can be by peace
Dress seat is connected with high frequency driver.
Used as further improvement, the air deflector part is in trunnion, and it is outer and outside that another part is located at shell
During the jugular groove of high frequency driver is stretched into during shell connection high frequency driver.；Manifold is close to be distributed in air deflector periphery.
Used as further improvement, the inside the shell is additionally provided with phase plug, and the phase place plug portion is in trunnion.
Used as further improvement, the part that air deflector is stretched out outside shell is cone, and in cage connection high-frequency drive
Its microcephaly is located in jugular groove during device, and major part is near trunnion；When the shell of high frequency bugle is connected with high frequency driver, high frequency bugle
Manifold be connected with the jugular groove of high frequency driver.
Used as further improvement, the phase plug is close to air deflector near one end of face.
Used as further improvement, the cover top portion both sides are also arranged with bugle lip.
Used as further improvement, the outer shell outer wall is also close to be provided with the reinforcement for removing resonance.
As further improvement, bugle resonance abatement type position is additionally provided with the top of the shell, the manifold is in streamline
Type curve.
Used as further improvement, the cross section of the shell is quadrangle；The phase plug is gradually thinning from bottom to up,
In front and back both sides are domatic, and being projected as left and right sides in the vertical direction is streamlined, and top is arc；Each side of phase plug
It is corresponding with the side of a quadrangle.
The present invention has the beneficial effect that：
1) present invention, can be with the upper limiting frequency of significant increase bugle by arranging manifold.
2) reflecting surface in shell (extension) is additionally arranged phase plug, can prevent standing wave and intermodulation distortion so that off-axis
Frequency response diffusion property and more smooth to axle frequency response diffusion property, it is to avoid the off-axis frequency response peak valley phenomenon that Jing often occurs in bugle,
Greatly reduce clarino.
3) because high frequency driver has a sounding larynx, bugle trunnion dimensions is typically consistent with sounding larynx could to match somebody with somebody
With, and bugle of the prior art is all not provided with conical bugle air deflector, is exactly a straight larynx, sound wave ability it is excessive or
Sound focusing can be produced when too small, i.e., sound wave gas explosion (horn sound) is shown as when excessive, sound node is shown as when too small
Separate with bass unit, and then generation there is not bass or there is not the defect of high pitch, the present invention arranges air deflector, eliminates high frequency driver
Sound focusing in jugular groove, realization has the effect of high pitch and bass.
4) bugle lip is set, bugle length is extended, bugle lower limit effective frequency is improved.
5) the reinforcement and bugle resonance abatement groove of resonance is provided for, the intensity for making bugle is greatly increased, greatly
The mechanical oscillation of bugle when reducing work, the sound wave for making bugle exports more stable.
