Sound acquisition assembly and intelligent equipment

Abstract

The invention discloses a sound acquisition assembly and intelligent equipment. The sound acquisition assembly comprises a fixing frame, support rods and microphones. The eight microphones are correspondingly installed on the eight support rods, and the eight microphones are arranged along the same circumference. Four included angles in eight included angles formed between every two adjacent supporting rods are 30 degrees, the other four included angles are 60 degrees, every two of the four 30-degree included angles are oppositely arranged, and every two of the four 60-degree included angles are oppositely arranged. Any two microphones are matched with each other, so that the sound acquisition assembly forms a binary array sound acquisition device. The three microphones of which the included angles between every two microphones are 120 degrees are matched with one another, so that the sound acquisition assembly forms a ternary array sound acquisition device. The four microphones of which the included angle between every two microphones is 90 degrees are matched with one another, so that the sound acquisition assembly forms a quaternary array sound acquisition device. The six microphones of which the included angle between every two microphones is 60 degrees are matched with one another, so that the sound acquisition assembly forms a six-element array sound acquisition device.

Description

technical field [0001] The present invention relates, 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 different algorithms are used...

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
