Abstract
The invention discloses a kind of microphone array device for 3D immersion surround sound music and video display pickup, microphone is pointed to including six the heart-shaped of same model, the microphone be divided into above and below two layers arrangement, upper strata is using two microphones, spacing is provided between its microphone cartridge, the axial angle of vibrating diaphragm is 110 degree of sensings, microphone formed plane and horizontal plane；Four microphones that lower floor is set using adjacent spaces into square；The central point of four microphones in axial angle top and lower floor of two, upper strata microphone vibrating diaphragm is overlapped in the vertical.The present invention can solve to make immersion surround sound production of film and TV and music recording technical problem.
Description
Technical field
The present invention relates to a kind of sound pick up equipment.
Background technology
In recent years, rapid spread in film industry of the concept of immersion surround sound was come, Dolby Labs and Ba Kegong
Department is also proposed respective immersion surround sound solution A tmos and Auro-3D respectively, and in manufacturing terminal two, company also focuses on
Application of the immersion surround sound in post-production is emphasized, and for the outdoor scene pickup of immersion surround sound, is substantially belonged to
Technological gap.
Prior art is also in stereo and surround sound pickup substantially, and the pickup for immersion sound is not transaudient
Device array.
The content of the invention
Equipped it is an object of the invention to provide a kind of microphone array for 3D immersion surround sound music and video display pickup
Put, to solve to make immersion surround sound production of film and TV and music recording technical problem.
In order to realize foregoing invention purpose, the technical solution adopted in the present invention is as follows：
For the microphone array device of 3D immersion surround sound music and video display pickup, including six point to it is identical if
Cylinder, the microphone be divided into above and below two layers of arrangement, upper strata is provided with spacing, the axle of vibrating diaphragm using two microphones between its microphone cartridge
It is 110 degree of sensings, microphone formed plane and horizontal plane to angle；Lower floor uses four that adjacent spaces are set into square
Microphone；The central point of four microphones in axial angle top and lower floor of two, upper strata microphone vibrating diaphragm is overlapped in the vertical.
The microphone points to microphone using heart-shaped.
The lower floor uses cartridge spacing to point to microphone for the four heart-shaped of 19cm~21cm, into square setting；It is described
Upper strata microphone cartridge spacing is 16cm~18cm.The upper and lower layer arrangement spacing is 16~18cm；Upper and lower layer is talked about from the side
Cylinder cartridge is about in a positive side triangle.
Heart-shaped point to of six same models is cased with hurricane globe respectively outside microphone.
Advantages of the present invention and good effect are as follows：The present invention is used in the immersion surround sound form sound of music and video display
The pickup of sound, had both met the pickup of immersion surround sound, while being easy to carry out under surround sound and stereo format material
Conversion, it is obvious by multiple integration of operation using effect.
Brief description of the drawings
Fig. 1 is the upper strata microphone distribution schematic diagram of the present invention.
Fig. 2 is lower floor's microphone distribution schematic diagram of the present invention.
Fig. 3 is the front view of the present invention.
Fig. 4 is Fig. 3 top view.
Embodiment
The structure of the present invention is referring to shown in Fig. 3,4, the microphone array for 3D immersion surround sound music and video display pickup
Array apparatus, includes the heart-shaped of six same models and points to microphone, it is described it is heart-shaped point to microphone be divided into above and below two layers of arrangement.Referring to figure
Shown in 1, upper strata is provided with spacing using two heart-shaped point between microphone, its microphone cartridge, and the axial angle of vibrating diaphragm is 110 degree and referred to
To microphone formed plane and horizontal plane.It is shown in Figure 2, four hearts that lower floor is set using adjacent spaces into square
Shape points to microphone；With the four heart-shaped center for pointing to microphone of lower floor at the top of the two heart-shaped axial angle for pointing to microphone vibrating diaphragm in upper strata
Point is overlapped in the vertical.Unit is cm in Fig. 1,2,3,4.
The lower floor uses cartridge spacing to point to microphone for the four heart-shaped of 19m~21cm, into square setting；On described
Layer microphone cartridge spacing is 16cm~18cm；The upper and lower layer arrangement spacing is 16~18cm.
Six microphones are connected by support, form said structure.The heart-shaped of six same models points to microphone
It is outer to be cased with hurricane globe respectively.
According to the requirement of different recording technology schemes, the microphone of being differently directed property can be used to be replaced, two layers up and down
Spacing between microphone array column pitch and microphone can be also adjusted.
