Abstract
A directional microelectromechanical systems (MEMS) microphone, including a first layer, a second layer, and a third layer stacked in sequence and multiple adhesive members formed between the first layer, the second layer, and the third layer, is provided. The adhesive members include an outer adhesive member disposed surrounding a periphery of the first layer, the second layer, and the third layer and an inner adhesive member disposed within a range surrounded by the outer adhesive member. The outer adhesive member and the inner adhesive member form at least two slits between the first layer, the second layer, and the third layer. An external sound is transmitted to a sound sensing element after passing through two receiving holes of the directional MEMS microphone respectively along two paths. One of the two paths passes through the at least two slits.
