FIELD: acoustics.
SUBSTANCE: invention relates to devices for receiving and reproducing sound. Acoustic device contains a body having a cavity and several holes, each hole provides communication between the cavity and the outer space; several microphones located in the cavity and made with the possibility of capturing sound through the holes, several sound channels located in the cavity. The channels are located between the microphone and the hole so that the sound is transmitted to the microphone through the channel after passing through the hole. The device contains several speakers, a control circuit containing a plurality of controls. Each control corresponds to one speaker. The holes are located on the side of the cabinet facing away from the speaker. The control scheme contains many interactive nodes. Each interactive node corresponds to one speaker and the corresponding speaker control. The interactive node is configured to launch a control corresponding to the interactive node to control the corresponding speaker to implement the function corresponding to the user's work instruction in response to receiving the user's work instruction.
EFFECT: improvement of acoustic characteristics, reduction of wind noise impact.
