Abstract: A method and a system for acquiring the natural frequency of a diaphragm, wherein, the method comprises: selecting test frequency points in a closed space, converting an electric signal into an acoustic signal, directing sound into the closed space, and acquiring the acoustic pressure of each test frequency point; adjusting the electric signal until the acoustic pressure of each test frequency point is the same; converting the adjusted electric signal into an acoustic signal; acquiring the displacement generated by the vibration of the diaphragm; and taking the frequency corresponding to the maximum displacement of the diaphragm as the natural frequency of the diaphragm. By adopting the method and system, the natural frequency of the diaphragm is determined by acquiring the maximum displacement of the diaphragm. Moreover, the process of acquiring the natural frequency of the diaphragm is not affected by surrounding environment, and therefore the acquired result is more accurate.

Abstract: A multi-diaphragm speaker comprises at least four diaphragms, inner connecting rods, and outer connecting rods. The diaphragms located at odd-numbered positions are connected to the inner connecting rods via connecting points, and then the inner connecting rods are connected via the outer connecting rods, thus forming a first set of diaphragms. The diaphragms located at even-numbered positions are connected to the inner connecting rods via connecting points, and then the inner connecting points are connected via the outer connecting rods, thus forming a second set of diaphragms. The long rods and short rods of the inner connecting rods in the first set of diaphragms and in the second set of diaphragms are staggered. The present invention can implement connection of diaphragms without requiring penetration of the diaphragms, thus preventing occurrences of air leakage and poor sound quality, and enhancing sound effects of the speaker.

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.
