One kind of valve and speaker

The present invention discloses a valve and a speaker, the former includes a valve body (11), an elastic valve plate (12), through the valve body (11), the outer surface (11b, 11a) of the inlet opening (13 inside), and the through valve (12), an outer surface (12b, 12a) of the hole (14), the valve plate (12) and the valve body (11) surrounds the sealed connection is formed vent (14) and the inlet opening (13) an annular sealing zone and the inner surface of the body (11), (11b) covering a hole (14), and / or a valve plate (12) inner surface (12b) covering the inlet opening (13); after there is provided by the valve of the present invention. The elastic deformation of the valve sheet of the present invention utilizes the realization of the valve opening and closing, and therefore may have a thin thickness, which makes it smaller volume product can be a perfect match to a micro speaker, for example, thereby greatly reducing the limited space debugging difficult this kind of miniature speakers.
