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.
