Automobile Headrest with Integrated Core Speaker Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional automobile headrests with U-shaped support members limit speaker placement and require additional assemblies, making them less flexible and more costly, especially in compact cars where space is limited.
Innovation Solution
A headrest design featuring a main body with integrated speakers and a core that supports them, eliminating the need for a U-shaped support member, allowing for greater speaker placement freedom and reduced component count, with speakers positioned directly behind the user's head and centered within the headrest, and using a unitary molded plastic core and covers to define acoustic chambers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a U-shaped support member is used in traditional headrests, then structural support is provided, but speaker placement flexibility is limited and additional assemblies are required
Solution Approach 1:
The patent merges the support function and speaker mounting function into a single integrated core structure. The core includes recesses that directly receive and secure speakers, eliminating the need for separate U-shaped support members and additional mounting assemblies. This integration reduces the number of components and simplifies the overall assembly process while maintaining both structural support and speaker placement capabilities.
2Adaptability or versatility
If speakers are positioned directly behind the user's head, then acoustic performance is improved, but traditional U-shaped support members constrain this positioning
Solution Approach 1:
The core structure is segmented to include specific recesses positioned to receive speakers directly behind where the user's head would be. This segmentation allows speakers to be placed in the optimal acoustic position while the overall core structure maintains structural integrity. The recesses are strategically located in the core to enable direct-back speaker positioning without requiring a U-shaped support member.
3Ease of manufacture
If additional assemblies and connecting components are used to secure speakers, then speaker mounting is achieved, but manufacturing cost increases
Solution Approach 1:
The core structure is designed as a single integrated component that combines support functionality with speaker mounting capability. The recesses in the core directly receive and secure speakers, eliminating the need for separate U-shaped support members, stays, and multiple connecting components. This reduction in component count simplifies the manufacturing process and reduces overall manufacturing costs.

AI summary
An automobile headrest includes a main body portion having a front surface arranged to support a back of a head of a user. The main body portion includes first and second speakers which are disposed within the main body portion, and a core that is configured to support the speakers. The automobile headrest also includes a pair of support rods that are connected to the core. The core is configured such that at least a portion of the speakers is disposed directly behind the head of the user when the back of the user's head rests against the front surface of the main body portion and is centered relative to the main body portion. The core defines a portion of one or more acoustic chambers for the first and second speakers.
