Embodiment Construction

[0011] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0012] The present invention provides a kind of recording equipment, through a plurality of mutually layered arrangements, with ear structure and facial contour fixing device, the audio collector is set at the ear canal opening of the ear structure to collect audio information, when audio collection, The horizontal orientation of the face of each fixing device is different, so that the audio collector can acquire the audio information at the ear canal opening of the ear structure facing each horizontal direction, ensuring rich sound sources and sound authenticity, rich in texture, and has a stereosc...

Abstract

The present invention is applicable to the field of audio recording and provides an audio collection apparatus. Multiple fixed apparatuses are stacked and have ear structures and face contours, and audio collectors are disposed at ear canal openings of the ear structures to collect audio information. During audio collection, faces of the fixed apparatuses have different horizontal orientations, so that the audio collectors obtain the audio information at the ear canal openings of the ear structures towards horizontal directions. Therefore, rich sound sources and sound authenticity are ensured, sounds are rich in quality, a stereo field perception effect is achieved, a real sound field relationship can be restored, an in-head effect is avoided, and a requirement for real synchronization between a sound and an image in a virtual reality (VR) panoramic video technology is met.

Description

technical field [0001] The invention belongs to the field of audio recording, in particular to an audio collecting device. Background technique [0002] In traditional computer graphics technology, the change of the field of view is realized through the mouse or keyboard, and the user's visual system and motion perception system are separated. With the development of VR (Virtual Reality, virtual reality) panoramic video technology and Popularity, the use of head tracking to change the perspective of the image, so that the user's visual system and motion perception system have established a connection, the user can observe the scene presented in front of the user through the movement of the head. VR panoramic video equipment allows users to watch videos at any angle of 360°. In order to enable VR panoramic video technology to bring users a stereoscopic experience, the audio recording technology in panoramic video has also become a focus. When the human ear receives sound wav...
