| description | The invention provides sound pickup equipment, method, device and system and a storage medium. The equipment comprises a sound cover and a microphone array, two side edges of the axial section of the sound cover are two inclined straight line sections which are symmetrical along the axis of the sound cover; and the microphone array is arranged on the axis in the sound cover. According to the sound pickup equipment, method, device and system and the storage medium provided by the invention, incident sound waves are uniformly dispersed to the microphone array deployed on the axis of the sound cover by arranging the sound cover of which the axial section side edges are two inclined straight line sections symmetrical along the axis, so that the area for receiving sound source sound signals is increased. Therefore, the radiation sound energy of the received long-distance sound source is improved, the sensitivity of the microphone is improved, the optimal super-directivity wave beam can be designed through the micr |
