Abstract
The present invention disclosed a micro acoustic collector with a lateral cavity, comprising: a base metal layer; a movable film, an annular side wall; a lateral metal layer. The movable film faces towards the base metal layer to form a hollow space. The lateral metal layer is formed at a side of the movable film and around the movable film, fixed by the annular side wall and spaced apart from peripheral of the movable film by a distance, and the lateral metal layer faces towards the base metal layer to form a lateral cavity to assist an acoustic collection.
