摘要： A speaker comprises at least four diaphragms, inner connecting rods, outer connecting rods, and a cavity sealing housing. Diaphragms spaced apart from each other respectively form a set of diaphragms. The two sets of diaphragms move relative to each other. Connecting points are provided on rigid domes of each of the diaphragms. The inner connecting rods are connected to the diaphragms via the connecting points on the domes. The inner connecting rods respectively connected to the two sets of diaphragms are connected one to another via different outer connecting rods. Cavities of the speaker are formed between adjacent diaphragms. Cavities spaced apart from each other jointly form a front acoustic cavity. The cavities adjacent to the front acoustic cavity form a rear acoustic cavity. The cavity sealing housing seals the front acoustic cavity/rear acoustic cavity, thus allowing separation of the front and rear acoustic cavities of the speaker.

摘要： 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.
