[0005]为了实现上述发明目的,本发明所采用的技术方案如下: [0005] In order to achieve the above object, the technical solution employed in the present invention is as follows:

用于3D沉浸式环绕声音乐与影视拾音的传声器阵列装置,包括六个指向相同的话筒,所述话筒分为上下两层布置,上层采用两只话筒,其话筒极头间距设置,振膜的轴向夹角为110度指向,话筒所成平面与水平面垂直;下层采用相邻间隔成正方形设置的四只话筒;上层两只话筒振膜的轴向夹角顶部与下层四只话筒的中心点在纵向上重合。 For immersive 3D Surround microphone array pickup apparatus acoustic music and video, the same six points including a microphone, the microphone is arranged divided into two layers, upper layer uses two microphones, microphone poles which spacing setting, diaphragm axially directed angle of 110 degrees, perpendicular to the horizontal plane into a microphone; intervals adjacent to the lower layer using a square four microphones disposed; upper two microphone diaphragm and a top angle of an axial center of the lower four microphones It coincides with a point in the longitudinal direction.

[0006]所述话筒采用心形指向话筒。 The [0006] microphone using cardioid microphones.

[0007]所述下层采用极头间距为19cm〜21cm的四只心形指向话筒,成正方形设置;所述上层话筒极头间距为16cm〜18cm。 [0007] The lower pole head using a pitch of four cardioid microphones pointing 19cm~21cm, arranged in a square; the upper head microphone pole pitch 16cm~18cm. 所述上、下层布置间距为16〜18cm;从侧面看上、下层话筒极头约呈一正边三角形。 The upper and lower layers are arranged spacing 16~18cm; spotted from the side, the lower layer was about a microphone positive poles of an equilateral triangle.

[0008]所述六个相同型号的心形指向话筒外分别套有防风罩。 [0008] The same type of six cardioid microphone are sheathed with the outer windshield.

[0009]本发明的优点及积极效果如下:本发明使用于音乐与影视的沉浸式环绕声格式声音的拾取,既满足了沉浸式环绕声的拾音,同时便于对素材进行环绕声与立体声格式的下变换,经过多次联合作业使用效果明显。 [0009] The advantages of the present invention and the following positive effects: the present invention is applied to music and video format immersive surround sound pickup, both to meet the pickup immersive surround sound, while allowing for creatives surround stereo format down conversion, through a number of joint operations, the results significantly.
