The invention provides an automatically adjusted microphone array, a method for automatically adjusting the microphone array and a device carrying the microphone array, wherein the automatically adjusted microphone array comprises the microphone array for collecting sound of a sound source, a collecting unit for detecting space parameters of the sound source in the space, a processing unit connected with the collecting unit and used for generating control signals when the space parameters satisfy the predetermined conditions, and a microphone array control unit connected with the microphone array and the processing unit and used for adjusting the microphone array according to the control signal so that the sound collected by the adjusted microphone array is coincident with the scheduled sound standard. The technology provided by the embodiment of the invention is used for automatically adjusting according to states of users so as to improve conversation or recording quality, and avoid many problems caused by the setting of the fixed parameters.
Description
technical field [0001] The invention relates to microphone technology, in particular to an automatically adjusted microphone array, a method and a device carrying the microphone array. Background technique [0002] With the development of digital microphone technology, due to the advantages of digital microphone array (SAM, Small Array Microphone) that can capture sound sensitively, suppress environmental noise more effectively, and eliminate echo more effectively, it is increasingly widely used in applications such as computers, mobile terminals, video Players MP3 / 4, cameras and video cameras and other electronic equipment. [0003] Digital microphone arrays are widely used due to the use of such figure 1 For the pickup angle technology shown, the pickup angle can be placed back-to-back or side-to-side by the main microphone (Uni-MIC) and the reference microphone (Omni-MIC) to form an array, using two microphones The difference in physical characteristics is processed by ...
