Abstract: A multi-diaphragm speaker system comprises a speaker apparatus and a front/rear cavity sealing apparatus. The speaker apparatus comprises at least four diaphragms. Cavities of the speaker apparatus are formed between every two adjacent diaphragms of the speaker apparatus. The cavities that are spaced apart from each other jointly form a first acoustic cavity of the speaker apparatus. The cavities adjacent to the first acoustic cavity form a second acoustic cavity of the speaker apparatus. The first acoustic cavity and the second acoustic cavity are separated via the front/rear cavity sealing apparatus. Utilization of the present utility model solves the problem of speaker front/rear cavity separation.
