Abstract: A loudspeaker module comprises an outer casing in which a vibration system and a magnetic circuit system are received. The magnetic circuit system comprises a basin-like stand fixed on the outer casing. The outer casing comprises a second casing provided with a rear sound exit hole that transversely runs through the inner side surface and the outer side surface of the second casing at the position corresponding to the outer side surface of the sidewall of the basin-like stand. The rear sound exit hole is communicated with an inner cavity of the module and an inner cavity of the electronic terminal. A chamfered plane is disposed at an upper end of the sidewall of the basin-like stand, and on a side of the sidewall of the basin-like stand. A sound emitting channel is formed between the chamfered plane and the inner side surface of the second casing.

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.
