Speaker Module Wire Suspension for Projector Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of projector speakers due to specialized screws and the limited versatility of rubber dampers, which can deform and affect shock absorption and sound quality.
Innovation Solution
A speaker module that uses wires instead of screws and rubber dampers to suspend the speaker, reducing manufacturing costs and improving shock absorption and tone quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to lock the speaker, then the speaker can be firmly fixed, but the manufacturing cost increases due to special screws
Solution Approach 1:
The invention removes the screw component entirely from the speaker mounting system. Instead of using screws to lock the speaker, the design extracts this fastening function and replaces it with a screwless mounting structure that achieves secure fixation without requiring special screws, thereby reducing manufacturing cost while maintaining fixed strength.
Solution Approach 2:
The invention creates a universal mounting structure that can accommodate different speaker shapes and sizes without requiring different fastening components. The screwless design uses a standardized base structure with rubber dampers that can adapt to various speaker configurations, making the mounting system multi-functional and versatile across different speaker types.
2Reliability
If rubber dampers are used for shock absorption, then the speaker can be protected from vibration, but the dampers deform and affect shock absorption effect and tone quality
Solution Approach 1:
The invention incorporates rubber dampers in advance between the speaker and the base structure to provide pre-positioned shock absorption. These dampers are installed during manufacturing to cushion vibrations before they can cause damage, protecting the speaker from vibration-induced stress while maintaining their shock absorption capabilities through proper material selection and positioning.
Solution Approach 2:
The invention optimizes the physical parameters of the rubber dampers, such as material composition, hardness, and geometric dimensions, to enhance their shock absorption performance. By carefully selecting and adjusting these parameters, the dampers can effectively absorb vibrations without deforming under normal operating conditions, thereby maintaining both shock absorption effect and tone quality.
3Adaptability or versatility
If different shapes of speakers are mounted, then various speaker types can be accommodated, but different rubber dampers are needed reducing versatility
Solution Approach 1:
The invention designs a universal base structure with standardized mounting features that can accommodate different speaker shapes and sizes. The base includes generic attachment points and a standardized rubber damper configuration that works with various speaker types, eliminating the need for different damper variants and maintaining versatility across speaker configurations.
Solution Approach 2:
The invention separates the speaker mounting system into modular components: a standardized base structure, universal rubber dampers, and adaptable speaker mounting interfaces. This segmentation allows the core base and damper system to remain consistent while accommodating different speaker types through flexible interface design, reducing the need for multiple damper varieties.

AI summary
A speaker module includes a base, a speaker and a wire. The base has a bottom and a first wire fixing portion. The speaker is disposed in the base and has a second wire fixing portion. The wire is fixed to the first wire fixing portion and the second wire fixing portion to suspend the speaker in the base, and the speaker is separated from the bottom with a distance. A projection device having the speaker module is further provided.
