Electronic product

Abstract

The invention provides an electronic product. The electronic product comprises a shell and a sound sensor array which is arranged in the shell and is composed of at least two sound sensor units, wherein sound holes corresponding to sound sensor units are arranged on the shell; the center spacing between two of the sound sensor units is less than the spacing between two of the sound holes on the shell; and the sound sensor units are respectively communicated with the corresponding sound holes on the shell by relatively diffused and extended sound channels. According to the electronic product, a plurality of sound sensor units can be arranged adjacently without increasing internal size of product, and the outside signal receiving positions of the sound holes of a plurality of sound sensors are extended by relatively diffused and extended sound channels, so that the spacing between two of the sound holes in the sound sensors is realized.

Description

technical field [0001] The present invention relates to the technical field of microphone application, and more specifically, to an electronic product using a microphone product. Background technique [0002] With the progress of society and the development of technology, the penetration rate of small portable electronic products such as mobile phones is getting higher and higher. Generally, small portable electronic products such as mobile phones are equipped with sound sensors to receive external sound signals. In recent years, as electronic products have higher and higher requirements for voice input performance, the requirements for noise reduction have become more stringent. The microphone of a pickup has a single function, and it is difficult to realize some specific functions, which cannot meet the diversified needs of the current portable electronic products for the microphone. [0003] Therefore, some electronic products begin to use at least two sound sensors to f...

Problems solved by technology

But for the sound sensor array disclosed in the patent application number 200820043724.4, in order to achieve the necessary acoustic performance, it is necessary to achieve sufficient phase difference. There is no phase difference or time difference, and the acoustic signal cannot be processed, so the center-to-center distance of the sound sensor unit is required to be large

[0004] However, as we all know, the size of portable electronic products such as mobile phones is rapidly decreasing, and the space for installing various components inside is also gradually shrinking. The overall size of the sound sensor used is generally reduced to less than 10 cubic millimeters, combining multiple sound sensors Installed in different positions, in addition to occupying the internal space of electronic products, it also increases the complexity of installation, complex circuit layout, increased production costs, and decreased product reliability.
