Abstract

This application discloses a sound acquisition component array, including: two first sound acquisition components, two second sound acquisition components, and two third sound acquisition components. The two second sound acquisition components are located at a first side of a line connecting the two first sound acquisition components, and the two third sound acquisition components are located at a second side of the connecting line that is opposite to the first side of the connecting line; the two second sound acquisition components are symmetrical about a perpendicular bisector of the connecting line, and the two third sound acquisition components are symmetrical about the perpendicular bisector; and a distance between the two first sound acquisition components, a distance between the two second sound acquisition components, and a distance between the two third sound acquisition components are respectively different from one another along a direction defined by the connecting line.

First claim

What is claimed is:

the two second sound acquisition components are symmetrically positioned to each other with respect to a second line, wherein the second line is a perpendicular bisector of the first line;
the two third sound acquisition components are symmetrically positioned to each other with respect to the second line;
a first distance between the two first sound acquisition components along a first direction of the first line, a second distance between the two second sound acquisition components along a second direction parallel to the first line, and a third distance between the two third sound acquisition components along a third direction parallel to the first line being respectively different from one another; and
each of the first distance, the second distance, and the third distance is divided into two halves by the second line that is perpendicular to the first line, such that each pair of the two first sound acquisition components, the two second sound acquisition components, and the two third sound acquisition components are located on two opposite sides of the second line.

2. The sound acquisition component array according to claim 1 , wherein
the first distance between the two first sound acquisition components is three times the second distance between the two second sound acquisition components; and
the third distance between the two third sound acquisition components is twice the second distance between the two second sound acquisition components.

3. The sound acquisition component array according to claim 2 , wherein
a vertical distance between the two second sound acquisition components and the first line is the same as that between the two third sound acquisition components and the first line.

4. The sound acquisition component array according to claim 3 , wherein:
a ratio of the second distance between the two second sound acquisition components to the vertical distance between the two second sound acquisition components and the first line is 5:2.

5. The sound acquisition component array according to claim 1 , wherein the sound acquisition component array is a microphone assembly or a pickup assembly.

6. The sound acquisition component array according to claim 1 , wherein the six sound acquisition components are located on the same plane.

7. The sound acquisition component array according to claim 1 , wherein
