Abstract: The key design methods of microphone array structure matching and the influence of microphone array and speaker placement position are studied. The attention points that affect the acoustic structure of microphone array are comprehensively described, and its application in air conditioning is comprehensively analyzed. The proposed design methods and attention points are verified by corresponding engineering tests, which can meet the product application requirements, can better guide the design and production of voice air conditioning.

Key words: Microphone array, Placement position, Structure matching, Design method, Key points, Air conditioning application
