A glass panel that improves the sound gathering effect of the microphone

Abstract

The invention discloses a glass panel with an improved microphone sound collecting effect. The glass panel comprises a sound receiving head, a sound collecting cavity, an adjusting member and a base.The sound receiving head serves as a microphone sound collecting structure. The sound collecting cavity includes a sound insulation layer and a sound collection layer; the sound collection layer is aglass panel having a conical structure rotating around the sound receiving head and is in a screw joint relationship with the sound receiving head; a plurality of spherical grooves for sound reflection are formed uniformly in the inner wall of the sound collection layer; and the sound insulation layer is adhered to the outer peripheral side of the sound collection layer to realize ambient noise isolation. The adjusting member consists of a connecting body and a rotating body that are integrated into one. The base includes a rotation base body and a support rod; the rotation base body is in a screw joint relationship with the support rod; a rotation groove is formed in one end of the rotation base body; and the adjusting member is clamped to the rotation base body based on cooperation of the rotating body and the rotation groove. With the glass panel disclosed by the invention, a problem of poor sound receiving effect in cooperation of the glass panel with the voice microphone is solved.

Description

technical field [0001] The invention relates to the technical field of sound-gathering glass, in particular to a glass panel capable of improving the sound-gathering effect of a microphone. Background technique [0002] When a person is speaking, the sound wave is transmitted. If an obstacle is encountered, it will cause a part of the reflection, resulting in a decrease in the ability of the voice microphone to accurately recognize the voice. [0003] The prior art CN206517560U provides a retractable sound-gathering microphone for interviews, including a sensor head for audio collection by the microphone, and a sound-gathering cover is provided outside the sensor head, and the sound-gathering cover is a spliced ​​structure of two vertebral cylinders , and the small ends of the two vertebral tubes are connected, and there are several uniformly arranged sound transmission holes on the upper periphery of the sound collection cover, the sound transmission holes run through the i...
