Abstract: An air valve and a speaker are provided. The air valve comprises a valve body, an elastic valve plate, an air inlet penetrating through an inner surface and an outer surface of the valve body, and an air outlet penetrating through an inner surface and an outer surface of the valve plate. The valve plate is connected with the valve body in a sealing manner to form an annular sealing area encircling the air outlet and the air inlet, and the inner surface of the valve body covers the air outlet, and/or the inner surface of the valve plate covers the air inlet. The speaker is provided with or incorporates the air valve. The air valve can be opened or closed via elastic deformation of the valve plate of the air valve.

Abstract: Described is an air valve and a speaker containing the air valve described. The air valve comprises a valve body, an elastic valve plate, an air inlet penetrating through an inner surface and an outer surface of the valve body, and an air outlet penetrating through an inner surface and an outer surface of the valve plate. The valve plate is connected with the valve body in a sealing manner to form an annular sealing area encircling the air outlet and the air inlet. The inner surface of the valve body covers the air outlet, and/or the inner surface of the valve plate covers the air inlet. The air valve can be opened or closed via elastic deformation of the valve plate of the air valve. Therefore, the air valve can be perfectly matched with smaller sized products, reducing the difficulty in adjusting the micro speaker in a limited space.
