Speaker Module Airtight Sealing for Space-Efficient Acoustic Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of adhesive materials with waterproof functions for speaker modules in electronic devices can damage components during compression, and the space required for sound phase separation reduces inner space utilization.
Innovation Solution
A speaker module design with a speaker unit, first speaker housing, and an airtight member that seals gaps without requiring a compression process, ensuring dustproof and waterproof functionality while optimizing inner space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an adhesive material having a waterproof function is used to block external foreign substances and moisture, then dustproof and waterproof functionality is improved, but a compression process is required which may damage electronic components or speaker modules
Solution Approach 1:
The patent extracts the sealing function from the adhesive material application process and integrates it into the speaker module housing structure itself. The housing includes a sealing groove and sealing protrusion that work together to block foreign substances and moisture without requiring separate adhesive materials or compression processes, thereby eliminating the damage risk to electronic components.
Solution Approach 2:
The patent introduces a sealing member as an intermediary component between the speaker module housing and the housing opening. This sealing member fits into the sealing groove and works with the sealing protrusion to create an airtight seal, eliminating the need for compression processes while ensuring dustproof and waterproof functionality.
2Reliability
If a housing structure is designed to separate spaces for sound transmission to prevent phase cancellation, then acoustic performance is improved, but the inner space utilization efficiency decreases
Solution Approach 1:
The patent merges the acoustic passage formation with the speaker module housing structure itself. The housing includes a sound transmission hole and acoustic passage that are integrated into the housing design, eliminating the need for separate space separation structures and thereby improving inner space utilization efficiency while maintaining acoustic performance.
Solution Approach 2:
The patent utilizes the vertical dimension by forming the acoustic passage through the thickness of the housing rather than occupying horizontal space. The acoustic passage extends from the inner surface of the housing through the housing thickness to the outer surface, allowing sound transmission without reducing the available inner space for other components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Eliminates component damage risks during assembly and improves inner space efficiency by eliminating the need for compression processes and sealing acoustic passages.
Implementation Method 1
an airtight member which seals a gap between the speaker module and the acoustic passage so that the sound radiated from the speaker unit is transmitted to the acoustic passage
Implementation Method 2
a speaker unit for reproducing a sound... a portion from which sound is radiated by the speaker unit

AI summary
An electronic device comprises a speaker module which includes a speaker unit and a first speaker housing that is coupled to the speaker unit in a first direction. The first speaker housing accommodates the speaker unit, and is arranged in the inner space of the electronic device. An opening for radiating sound allows the inner space of the electronic device to communicate with the outside, and an acoustic passage connects the opening for radiating sound and a portion from which a sound is radiated by the speaker unit of the speaker module. The speaker module can further include an airtight member for sealing a gap between the speaker module and the acoustic passage so that the sound radiated from the speaker unit is transmitted to the acoustic passage.
