Problems solved by technology

At present, digital HRTF cannot achieve the real effect of natural HRTF due to various limitations.
[0004] It can be seen that the above-mentioned existing methods obviously still have inconveniences and defects, and cannot create a more realistic sense of immersion, and need to be further improved.

specific Embodiment

[0036] In this embodiment, the bionic microphone sound pickup device takes 24 sound pickup channels as an example to describe its technical solution in detail. Specific examples are as follows:

[0037] Refer to attached figure 1As shown, the bionic microphone pickup device of this embodiment includes a socket 1 and a modular microphone head 2, and the socket 1 is provided with 24 multi-level multi-channel recessed sockets 11 for inserting the modular microphone head 2, 24 modules The microphone head 2 and the 24 concave sockets 11 are connected by a standardized standard interface, such as a Canon interface, which is convenient for plugging and unplugging, and has strong adaptability. That is, 24 modular microphone heads 2 form a human head recording pickup array, which is used to collect bionic audio information of different rotation angles of the human head.

[0038] Among them, refer to the attached Figures 2 to 4 As shown, the modular microphone head 2 adopts a bionic...

Abstract

The invention discloses a bionic microphone pickup device and a bionic spatial audio algorithm based on the same. The device comprises a socket and a modular microphone head, the socket is provided with at least two concave jacks used for inserting the modular microphone head, and the modular microphone head is connected with the concave jacks through standard interfaces. The modular microphone head is a bionic ear microphone head. The socket comprises an upper horizontal layer, a middle horizontal layer and a lower horizontal layer, and each horizontal layer is provided with one to four pairsof inwards-concave jacks which are oppositely arranged left and right. By using the multichannel bionic ear microphone head, bionic audio information of different rotation angles during look-up, head-up and top-down of a human head can be collected, and multichannel audio is calculated in real time and output to the earphone in combination with head movement track parameters, so that a more realistic sound effect of restoring a real sound field is achieved, and more excellent auditory experience is brought to people.

Description

technical field [0001] The invention belongs to the technical field of VR audio, and is a VR auditory solution based on a bionic spatial audio algorithm, which also includes a modular bionic microphone sound pickup device. Background technique [0002] For the human brain, hearing and vision work together, and only through sound judgments can humans make various responses in the real world. At present, VR technology is very popular among people. In order to create a realistic sense of immersion, VR headset manufacturers have tried their best to improve key technical parameters, such as refresh rate, head tracking delay, field of view, resolution, etc., but audio parameters are missing among these parameters. . This will cause users to only receive a large amount of disordered concurrent information after wearing the VR head-mounted display device, without sound guidance. This kind of experience can only bring richness in perception, and there is no sense of immersion at all...
