Speaker Module Protrusion Structure for Moisture Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased size of display areas in electronic devices has led to a higher likelihood of moisture interfering with the acoustic output of speakers, causing sound quality deterioration due to the longer internal space and potential blockage of the acoustic generation surface.
Innovation Solution
The implementation of a protrusion structure on the surface where the speaker module is received, which includes a rib with varying clearances and a waterproof member to prevent moisture from blocking the acoustic output and maintain sound quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display area is increased, then the display size is improved, but the internal space for acoustic connection becomes longer and moisture interference increases
Solution Approach 1:
The internal structure's surface is segmented into multiple areas with different clearances from the acoustic generation surface. This segmentation creates zones that can handle moisture differently, with certain areas having larger clearances to prevent moisture blockage while maintaining acoustic connection.
Solution Approach 2:
Different areas of the internal structure's surface are given different local qualities in terms of clearance distance from the acoustic generation surface. This allows specific regions to be optimized for moisture resistance while others maintain acoustic efficiency, addressing the moisture interference problem locally without compromising overall display size.
2Area of stationary object
If the internal space for acoustic connection is lengthened, then the display area can be increased, but the acoustic generation surface may be blocked by moisture
Solution Approach 1:
The internal structure surface is divided into multiple areas with varying clearances, creating a segmented approach to moisture management. This allows the acoustic connection path to be maintained while introducing strategic clearance zones that prevent moisture from blocking the acoustic generation surface.
Solution Approach 2:
The clearance parameter is varied across different areas of the internal structure surface. By changing this geometric parameter locally, the design optimizes both acoustic connection (requiring certain clearances) and moisture resistance (requiring larger clearances in specific zones), thereby maintaining acoustic output reliability despite the lengthened internal space.
3Object-affected harmful factors
If a protrusion structure is added to the speaker receiving surface, then moisture blockage is reduced, but the device complexity increases
Solution Approach 1:
The protrusion structure segments the internal space into multiple areas with different clearances from the acoustic generation surface. This segmentation creates natural moisture management zones without requiring additional separate components, reducing overall device complexity while effectively preventing moisture blockage.
Solution Approach 2:
The protrusion structure introduces a dimensional variation in the internal structure surface, creating areas with different clearances. This dimensional approach to moisture management allows effective moisture prevention through geometric design rather than adding separate functional components, thereby controlling device complexity.

AI summary
An electronic device is disclosed. The electronic device includes a housing, a display, at least one through-hole, a speaker module, and an internal structure. The housing includes a front plate, a rear plate, and a side member. The display and the speaker module are disposed between the front plate and the rear plate. The through-hole is formed through the font plate between a portion of the side member and the display. The speaker module includes an acoustic generation surface facing the front plate near the through-hole. The internal structure is disposed between the front plate and the acoustic generation surface. The internal structure and the acoustic generation surface form a space, acoustically connected to the through-hole. The internal structure includes a surface facing the acoustic generation surface. The surface of the internal structure includes a plurality of areas, each with a different clearance from the acoustic generation surface.
