Sound collection components and smart devices

Abstract

The invention discloses a sound collection component and an intelligent device. The sound collection component includes a fixing frame, a support rod and a microphone. Eight microphones are correspondingly installed on the eight support rods, and the eight microphones are arranged along the same circumference; The size of four of the eight included angles formed between the struts is 30 degrees, and the size of the other four included angles is 60 degrees. The angles are set opposite to each other; any two microphones are matched to form a sound collector of a binary array; the three microphones with an included angle of 120 degrees are matched to make the sound collection assembly A sound collector that forms a three-element array; four microphones with an angle of 90 degrees between the two are matched to make the sound collection component form a sound collector of a four-element array; the angle between the two is 60 degrees. The six microphones are matched to form a sound collector with a six-element array.

Description

technical field [0001] The invention relates to the field of data collection, in particular to a sound collection component and an intelligent device. Background technique [0002] The microphone array can obtain enough sound data, combined with different signal processing algorithms to realize various functions of IoT intelligent hardware, such as near-field sound collection, far-field sound collection, sound source localization, speech enhancement, blind source separation, etc.; Different algorithms have different requirements on the form and unit spacing of the microphone array, and different microphone arrays also have different advantages and disadvantages. At the same time, the type of microphone also has a direct impact on the acquisition of sound data. [0003] At present, the types of microphone arrays widely used include binary arrays, triple arrays, quadruple arrays, and six-element arrays, which are respectively used in smart speakers and other fields. If differ...

AI Technical Summary

Problems solved by technology

If different algorithms are used, it is necessary to match different microphone arrays and adjust the position of the microphones; to achieve different functions, different microphone array designs are also required. The existing two-element arrays, three-element arrays, four-element arrays, and six-element arrays Microphone arrays are designed separately. For example, when a smart device needs to use two or more of the microphone arrays of binary array, triple array, quadruple array, and six-element array, it needs to be equipped with multiple microphone arrays, which lacks universal and variability, which is not conducive to the cost control of products, and is not conducive to the miniaturization design of products
