Abstract

The invention discloses a micro loudspeaker module and a design method thereof. The module comprises an upper casing, a vibration system, a middle casing, a magnetic circuit system and a lower casing from the top to the bottom successively. The vibration system is arranged in the middle casing and is in seamless connection with the middle casing, a front cavity and a rear cavity of the middle casing are isolated completely through the upper casing, and preset-shape holes are formed in the wall of the rear cavity, so that the rear cavity and the outside can form gas exchange during the vibration of the vibration system. By means of the module and the design method, the preset-shape holes are formed in the wall of the rear cavity of the middle casing, the rear cavity and the outside can form gas exchange by the aid of the holes, and accordingly, large enough gas exchange space is provided, the design requirement of the micro loudspeaker module is guaranteed, and the problem that design space for the micro loudspeaker module become smaller and smaller and cannot meet the micro loudspeaker module design requirement in the prior art is solved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a micro speaker module and a design method thereof. Background technique [0002] At present, the speaker module of the mobile phone adopts the design with a rear cavity, and the rear cavity is basically from 0.5cm 3 to 1.5cm 3 wait. Usually, the structure of the speaker module is larger, and the rear cavity is correspondingly larger. [0003] However, as mobile phones are becoming thinner and more functional modules, the space left for the audio speaker module is less and less, and it is difficult to meet the requirement of 1cm for electroacoustic devices. 3 usage requirements. However, for existing miniature speaker modules, it is often less than 0.3cm 3 Condition. Contents of the invention [0004] The present invention provides a micro-speaker module and a design method thereof to at least solve the problem in the prior art that the design space left for the micro-...
