Abstract
A microphone assembly includes a microphone, an inner sleeve and an outer sleeve. The microphone has a shell, a diaphragm, a first sound receiving hole and a second sound receiving hole. The inner sleeve has a first hole and a second hole. The microphone is received between the first hole and the second hole. The inner sleeve is movable relative to the outer sleeve. The inner sleeve and the outer sleeve have at least two relative positions: in a first relative position, both the first hole and the second hole communicate with an outside environment; and in a second relative position, the first hole or the second hole communicates with the outside environment. The microphone assembly utilizes the relative movement of the inner sleeve and the outer sleeve to achieve directivity change.
