Abstract: The present invention provides a speaker module comprising a peripheral frame and speaker units housed in the peripheral frame, and the peripheral frame is provided with sound holes in communication with the outside, a front acoustic cavity in communication with the sound holes is defined between one side of the speaker units and the peripheral frame, and a rear acoustic cavity is defined between the peripheral frame and another side of the speaker units away from the front acoustic cavity; in which the speaker units are provided in plurality, and the rear acoustic cavity is divided into the same number of rear sub-cavities as that of the speaker units, and each of the speaker units corresponds to one of the rear sub-cavities and is in communication with its corresponding rear sub-cavity. The above structure makes it easier to adjust the acoustic performance and improves the stereo effect of the product.

Abstract translation: 本发明提供了一种扬声器模块，包括外围框架和容纳在外围框架中的扬声器单元，并且外围框架设置有与外部连通的声孔，与声孔连通的前声腔定义在一侧 的扬声器单元和外围框架，并且在外围框架和扬声器单元的远离前声腔的另一侧之间限定后声腔; 其中扬声器单元设置在多个中，并且后声腔被分成与扬声器单元相同数量的后子腔，并且每个扬声器单元对应于后子腔中的一个，并且是 与其相应的后子腔连通。 上述结构使得更容易调节声学性能并改善产品的立体效果。
