An omnidirectional pickup device

Abstract

The embodiment of the invention provides an all-directional pickup device which is used for carrying out pickup for an earphone listening mode. The all-directional pickup device comprises a supporting body and two microphones connected with the supporting body. The two microphones are symmetrically arranged on the two sides of the supporting body. The supporting body is filled with media capable of flowing, wherein the media capable of flowing are liquid or solid. The all-directional pickup device can pick up integrated sound field information through the arrangement of the supporting body and the microphones, amplification of time difference, volume difference and tone difference of stereophonic location information can be achieved, in this way, reproduced sound field effects in an earphone listening process are more real, locating is more accurate, more integrated sound field information can be restored, and the earphone listening effect can be improved.

Description

technical field [0001] The present application relates to the technical field of sound pickup, in particular to an omnidirectional sound pickup device. Background technique [0002] At present, the way people listen to music has gradually transitioned from the era of large-size speakers to the era of earphones through the era of bookshelf speakers. The effects of listening to music using earphones and loudspeakers are different. However, the structure of most sound pickup devices is not set for the earphone listening mode to pick up sound. [0003] For example, the relatively simple pickup device is only a microphone, and the stereo effect is completely completed by the post-production equipment of the mixing console. The method of realizing sound image positioning is only realized by adjusting the volume difference between the left and right speakers. The current ORTF (microphone system designed by the French Radio and Television Bureau), artificial head and other sound pi...

Problems solved by technology

The effect of listening to music with earphones and speakers is different. However, the structure of most sound pickup devices is not set for the earphone listening mode to pick up sound.

[0003] For example, the relatively simple pickup device is only a microphone, and the stereo effect is completely completed by the post-production equipment of the mixing console. The method of realizing sound image positioning is only realized by adjusting the volume difference between the left and right speakers. The current ORTF (microphone system designed by the French Radio and Television Bureau), artificial head and other sound pickup devices, although they can perform on-site stereo sound pickup, these sound pickup devices cannot restore and reproduce the sound when people listen to the picked up sound with headphones due to their own structure. All the sound field information, and people will not be able to hear high-quality omnidirectional music
