Abstract
The utility model discloses a kind of phase inverted cabinets, including babinet, the babinet is rectangular parallelepiped structure, the inside of the babinet has a host cavity, it is provided with loudspeaker unit in the host cavity, paraphase hole is distributed in the surrounding of the loudspeaker unit, and the paraphase hole is connected to the host cavity, and paraphase hole is distributed on four angles of babinet.By the above-mentioned means, a kind of phase inverted cabinet disclosed in the utility model, effectively spreads out the Frequency inside speaker, improves the coverage area of sound and increase the lowest resonance frequency lower limit of Frequency, enhance the rigidity and elasticity of babinet.
Description
Technical field
The utility model is related to sound-box device technical fields, more particularly, to a kind of phase inverted cabinet.
Background technology
Phase inverted cabinet is also referred to as inverted phase type trepanning case, and the emanant speaker of low frequency is to tie up to be provided with paraphase hole on Loudspeaker panel
（Slot）A kind of speaker.Paraphase slot is usually rectangular shape, also there is tubulose.Its position some close to loud speaker mounting hole,
Some board bottom portions in front.It by the partial sound of loud speaker backward radiation after conduit paraphase, before conduit mouth is radiated
Side.The sound given off from conduit mouth is superimposed in the same direction with diffuser forward radiation sound component, then together forward
Side is radiate, and as a result greatly strengthens the bass characteristic of speaker system.However, sound makes a sound in the babinet of speaker
Afterwards, the vibration that can cause babinet after being radiate by phase-reversing tube, can also lead to the vibration of phase-reversing tube, to cause babinet
Metal fatigue, to influence the structural integrity of babinet.Phase-reversing tube in existing phase inverted cabinet is all integrally fixed at speaker case
Internal portion so that staff is not easy to repair and replace, and phase-reversing tube is easy the mounting hole internal vibration on speaker, right
The sound quality of speaker has adverse effect on.
Utility model content
A kind of phase inverted cabinet of the utility model offer effectively will be inside speaker by the setting of the loudspeaker box structure
Frequency is spread out, and is improved the coverage area of sound and is increased the lowest resonance frequency lower limit of Frequency, enhances case
The rigidity and elasticity of body.
In order to solve the above technical problems, a kind of technical solution provided by the utility model is：A kind of inverted phase type sound is provided
Case, including babinet, the babinet are rectangular parallelepiped structure, and the inside of the babinet has a host cavity, is arranged in the host cavity
There are loudspeaker unit, the surrounding of the loudspeaker unit that paraphase hole is distributed with, the paraphase hole is connected to the host cavity, paraphase hole point
Cloth is on four angles of babinet.
The utility model, can be uniform by adopting the above-described technical solution, lead phase pore size distribution on four angles of babinet
The sound dispersion that the loudspeaker unit in babinet is sent out is gone out on ground, is increased the lower limit of lowest resonance frequency, is promoted sound frequency
Sensitivity and plumpness improve the sound quality of speaker.
Above-mentioned phase inverted cabinet, the loudspeaker unit are bass unit.
Above-mentioned phase inverted cabinet is provided with protection net on the outside of the loudspeaker unit, and the protection net is detachable
It is arranged on babinet.
Above-mentioned phase inverted cabinet is provided with handle on the both sides of the babinet.
Above-mentioned phase inverted cabinet is provided with suspender member at the top of the babinet.
The both sides of above-mentioned phase inverted cabinet, the front and back of the babinet are respectively arranged with preceding pendant and rear pendant.
Compared with prior art, acquired advantageous effect is the utility model：By being distributed on four angles of babinet
Paraphase hole will be connected to outside host cavity and babinet, and the sound that loudspeaker unit is sent out uniformly diffuses in host cavity through paraphase hole
Outside babinet, enhances acoustic energy and keep same phase；It, can be by forward and backward pendant and suspender member hanging in holder when using this speaker
On, it is easy for assemble or unload, and by handle can direct mobile box, be convenient for carrying.
Description of the drawings
Fig. 1 is a kind of decomposition texture schematic diagram of phase inverted cabinet of the utility model；
Fig. 2 is a kind of dimensional structure diagram of phase inverted cabinet of the utility model.
Specific implementation mode
Below in conjunction with the accompanying drawings and embodiment is described further the utility model：
Embodiment 1
Shown in referring to Figures 1 and 2, a kind of phase inverted cabinet, including babinet 1, the babinet 1 is rectangular parallelepiped structure, described
The inside of babinet 1 has a host cavity 10, and loudspeaker unit 2, the surrounding point of the loudspeaker unit 2 are provided in the host cavity 10
It is furnished with paraphase hole 3, the paraphase hole 3 is connected to the host cavity 10, and paraphase hole 3 is distributed on four angles of babinet 1.Specifically
, the loudspeaker unit 2 is bass unit.
The vibrating diaphragm of the woofer unit of phase inverted cabinet be should be understood that when front and back vibration, in addition to forward（Case
Outside）It, also can be towards radiative acoustic wave in case except radiative acoustic wave.If it is closed sound equipment, towards case in this acoustic wave segment energy for radiating
Amount just wastes, and the electro-acoustic transfer efficiency of loudspeaker reduces；Therefore, it is necessary to discharge the acoustic wave energy of box house, to carry
The electro-acoustic transfer efficiency of high loudspeaker.In the present embodiment, paraphase hole 3 is arranged on four angles of babinet 1, paraphase hole 3 and receiving
Chamber 10 is connected to, and therefore, the sound wave in host cavity 10 inside babinet 1 discharges after the back end reflective of babinet 1 from paraphase hole 3
Go out, the sound wave discharged from paraphase hole 3 keeps same phase with the sound wave discharged from bass unit 2, and which enhances the spokes of sound wave
Penetrate effect.
In addition, phase inverted cabinet described in the utility model, paraphase hole 3 and the side of babinet 1 are integrated, such sound
When wave propagates release from the paraphase hole 3, effectively enhances the impact force of sound wave and enhance the rigidity of babinet 1, reduction is radiating
Resonance when sound wave inside caused babinet 1.
Embodiment 2
Shown in referring to Figures 1 and 2, a kind of phase inverted cabinet, including babinet 1, the babinet 1 is rectangular parallelepiped structure, described
The inside of babinet 1 has a host cavity 10, and loudspeaker unit 2, the surrounding point of the loudspeaker unit 2 are provided in the host cavity 10
It is furnished with paraphase hole 3, the paraphase hole 3 is connected to the host cavity 10, and paraphase hole 3 is distributed on four angles of babinet 1.Specifically
, the loudspeaker unit 2 is bass unit.
In the present embodiment, the outside of the loudspeaker unit 2 is provided with protection net 4, and the protection net 4 is detachably arranged
