Wireless communication device with non-linear pickup arrangement matrix

Abstract

The invention provides a wireless communication device with a non-linear pickup arrangement matrix. The wireless communication device comprises a bottom shell and a surface shell, wherein the bottom shell has an accommodating cavity; the bottom shell comprises a side wall and a bottom wall; the surface shell is propped against the side wall so as to cover the accommodating cavity; the distance between the middle point of the side wall and the bottom wall is linearly increased from the distance between the end point of the side wall and the bottom wall; a first pickup, a second sound pickup anda third pickup are fixedly arranged in the accommodating cavity; the distance between the first pickup and the bottom wall, the distance between the second pickup and the bottom wall, and the distance between the third pickup and the bottom wall are different. Therefore, the arrangement matrix among the first pickup, the second pickup and the third pickup is non-linear and non-planar, the vibration interference of the loudspeaker is reduced, and the voice recognition accuracy rate is improved.

Description

technical field [0001] The invention relates to the field of wireless communication equipment, in particular to a wireless communication device with a non-linear pickup arrangement matrix. Background technique [0002] Existing wireless communication devices, such as wireless bluetooth voice control speakers or voice assistants, the arrangement matrix of the pickups inside it is usually distributed in four directions on a plane, or distributed linearly, and the distance from the speaker is very close, so it is easy to be affected by the speaker. vibration interference, it is difficult to improve the accuracy of surrounding sound recognition in this way. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a wireless communication device with a non-linear array of pick-ups, which reduces the vibration interference of the speakers, thereby improving the accuracy of voice recognition. [0004] The present invention is realiz...
