Abstract

The invention provides a loudspeaker module and an electronic product. The loudspeaker module comprises: a shell and a loudspeaker single body, wherein the loudspeaker single body is arranged in the shell and divides the shell into a front sound outlet area and a rear sound cavity; an acoustic pipeline, wherein the acoustic pipeline is provided with a sound inlet and a sound outlet, the sound inlet is communicated to the rear sound cavity, and the ratio L / S of the length L to the sectional area S of the acoustic pipeline is more than 1.6 / mm and less than 9 / mm; and a closed cavity, wherein thesound outlet of the acoustic pipeline is communicated with the closed cavity, and the sound transmitted from the sound outlet is closed in the closed cavity and is isolated from the sound transmittedfrom the front sound outlet area. The acoustic pipeline is arranged on the loudspeaker module, and the ratio of the length of the acoustic pipeline to the sectional area of the acoustic pipeline L / S is set to be greater than 1.6 / mm and less than 9 / mm, so that the resonant frequency of the loudspeaker module can be reduced, and the low-frequency sensitivity of the loudspeaker module below 500Hz canbe improved.

Description

technical field [0001] The present invention relates to the field of acoustic technology, and more specifically, the present invention relates to a loudspeaker module and an electronic product. Background technique [0002] As an electroacoustic conversion device, the speaker module is often used as a sound emitting device in electronic products. Due to the miniaturization of electronic products, the installation space of the speaker module is greatly reduced, and the size of the speaker module is increasingly restricted. The size of the loudspeaker module is reduced, and the volume of the rear cavity of the corresponding module is reduced, which has an adverse effect on the low-frequency performance of the loudspeaker module. Therefore, the low-frequency sound effect of the speaker module needs to be improved urgently, and the bass effect of the speaker module is mainly controlled by the volume of the rear acoustic cavity. When the volume of the rear acoustic cavity is lar...
