Abstract

The present invention discloses an audio acquiring device and an audio recording device, wherein, the audio acquiring device comprises the following components: a left earphone body; a right earphone body; a first microphone which is arranged on the left earphone body; a second microphone which is arranged on the right earphone body; and an interface component which has a first end that is respectively connected with the first microphone and the second microphone and a second end that is used for connecting with external equipment. Through the audio acquiring device of the invention, a problem of incapability of realizing stereo field perception by human ears in the prior-art audio acquiring device is settled, and furthermore an effect of improving stereo field perception degree by the human ears is obtained.

Description

technical field [0001] The present invention relates to the field of information processing, in particular to an audio collection device and an audio recording device. Background technique [0002] Traditional recording methods include single microphone recording, stereo recording (AB, XY, MS, ORTF). Figure 1a It is a schematic diagram of the appearance of a single microphone used for single-mic recording in the prior art, Figure 1b to Figure 1e It is a commonly used directivity configuration when recording with a single microphone. Although the recording with a single microphone is the easiest, the sound field is also the most monotonous; for this reason, the prior art also provides equipment for stereo recording. Figure 2a It is a schematic diagram of the appearance of the AB microphone used for stereo recording in the prior art, Figure 2b It is a schematic diagram of AB microphones relying on the distance attenuation of the sound field to achieve stereo field recordi...
