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 loudspeaker module comprises a housing and a loudspeaker unit. The housing is provided with an inner cavity for receiving and fixing the loudspeaker unit. A vibrating diaphragm of the loudspeaker unit partitions the inner cavity into a front sound cavity and a rear sound cavity. The front sound cavity is in communication with at least two sound uttering holes, and the at least two sound uttering holes are distributed on different sides of the housing. The electronic product comprises the loudspeaker module. By means of the technical solution of the present disclosure, the sound uttering holes are provided individually on different sides of a housing of a loudspeaker module. Due to the design of holes opened on at least two sides around the front cavity structure, the loudspeaker module having a side sound uttering structure reduces pipelines introduced during the implementation of the side sound uttering solution, and can achieve the effect of equivalently increasing the length of the sound uttering holes by increasing the number of the sound uttering holes, thereby extending the high-frequency characteristic of the electronic product having the loudspeaker module.

摘要： 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.

摘要： 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.
