Specific implementation mode
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
Embodiment 1
Referring to Fig. 1-2, a kind of phase inverted cabinet, including：Babinet 1, bugle 2, voice unit 3 and at least two are just the same
Bass unit 4；The front panel of the babinet 1 is provided with the bass installing port 11 and V-arrangement recess of at least two recess
Bugle installing port 12, bugle installing port 12 are arranged in the centre position of the front panel of babinet 1, and the bass installing port 11 is symmetrically set
It sets in the both sides of bugle installing port 12, the inside of the babinet 1 and the rear of the bugle installing port 12 is provided with high pitch
Installing port（It is not shown in figure）；The bass unit 4 is mounted on bass installing port 11, and the bugle 2 is mounted on bugle installing port
12, the voice unit 3 is mounted on high pitch installing port, and the rear end of the bugle 2 is connected with the front end of voice unit 3；The case
The also distributed paraphase hole 13 for being provided with the first quantity on the front panel of body 1.
It should be noted that paraphase hole 13 is another attachment inside speaker, it is exactly one section of hollow pipe in fact, usually uses
PVC material is made, and also has plenty of metal tube or cardboard tube, as long as internal diameter is identical with length, effect is the same.Paraphase hole 13
Pass through speaker front panel（Term is baffle）Or the one outlet of postnotum is communicated with free surrounding space, that outlet is exactly paraphase hole
13.13 not every speaker of paraphase hole has, and only phase inverted cabinet is just used, and closed speaker（It is exactly not have on babinet 1
The speaker of any opening）It is not have to paraphase hole 13.As its name suggests, paraphase hole 13 is just used on phase inverted cabinet, plays low frequency
Sound wave inverting function.Originally, the vibrating diaphragm of woofer is when front and back vibration, in addition to will be forward（Outside case）Radiative acoustic wave
Except, it also can be towards radiative acoustic wave in case.If it is closed speaker, towards case in this acoustic wave segment energy for radiating just waste, loudspeaker
Electro-acoustic transfer efficiency is natively low to have pity on, usually only a few percent, and waste in this way is really unfortunate, on babinet 1
A hole is opened, the low-frequency sound wave being radiated in case is released again.At will digging a hole can be not all right, because of the front and back sound radiated of vibrating diaphragm
Wave phase is exactly the opposite, if directly released, total low frequency energy cannot not only be reinforced, and can be cancelled weakening instead.So
The acoustic phase being radiated in case must be tried every possible means to overturn again primary, that is, invert 180 degree, thus with loudspeaker forward radiation
For sound wave with phase, paraphase hole 13 has been exactly this effect.
It should be noted that high-pitched speaker is installed from the rear side of babinet 1.The bugle 2 is sent out for spreading voice unit 3
Sound, the sound pressure level and projection distance of medium-high frequency frequency can be improved.At least two duplicate bass units, 4 same-phase is set
Meter, convenient for expanding application range and increasing projection distance.
In the present embodiment, the paraphase hole 13 is arranged on the periphery of bass installing port 11.Further, the bass list
Member 4 is 2, and first quantity is 8, and the surrounding of each bass installing port 11 is symmetrically distributed with 4 paraphase holes 13, this
Sample improves the Fo of speaker beneficial to the low frequency part in sound（Double bass）And reduce the non-linear distortion of sound wave at Fo.
The upper surface of the present embodiment, the babinet 1 is provided with the groove 14 placed side by side of the second quantity.It is excellent as one
It is 4 to select embodiment, the first quantity, is beneficial to reinforce 1 structure of babinet in this way, reduces resonance.
In the present embodiment, further include：Iron net 5；The iron net 5 is covered in the front panel of the babinet 1.Iron net 5 can prevent
Dirt keeps the cleaning of voice unit 3 and bass unit 4.
It is both provided with suspender member 15, the top of the front of the suspender member 15 in the two sides of the present embodiment, the babinet 1
It is provided with hanging hole 151, the following of the front of the suspender member 15 is provided with raised hanging portion 152, the suspender member 15
The top at rear portion is provided with the location hole 153 for 1 placement angle of regulating box, the following setting at the rear portion of the suspender member 15
The positioning region 154 of protrusion；The suspender member 15 is for connecting multiple babinets 1.The positioning region 154 of a upper babinet 1 is connected to down
The hanging portion 152 of the location hole 153 of one babinet 1, a upper babinet 1 is connected to the hanging hole 151 of next babinet 1, in this way
Can at least two babinets 1 are placed side by side, by this compact combination of babinet 1, the sound between speaker and speaker can be reduced
As interference.
In the present embodiment, the voice unit 3 is high-pitched speaker, and the bass unit 4 is woofer.
It is 110 ° of H × 9 ° V in the diffusion angle of the present embodiment, the bugle 2.It, can by 2 diffusion angle of bugle of setting
Increase audio frequency width, it is ensured that the consistency of audio coverage area and the uniform horizontal angle of coverage of holding.
The phase inverted cabinet of this programme is equipped with bugle 2, and the rear end of the bugle 2 and high pitch list in bugle installing port 12
The front end connection of member 3, can be improved the sound pressure level and projection distance of medium-high frequency frequency.In bass list on the front panel of the babinet 1
The distributed paraphase hole 13 for being provided with the first quantity around member 4, can run the low-frequency sound wave phase being radiated in case again
It is primary so that the low-frequency sound wave being radiated in case and the same phase of low-frequency sound wave being radiated outside case reduce non-linear distortion, and fall
The Distributed Design in phase hole 13 can make the coverage area of low-frequency sound wave consistent, and sound field is uniform, and it is equal to meet Sound image localization, sound field
The high-end technical indicator such as evenness.
Embodiment 2
