Open-Back Speaker Assembly for Localized Low-Frequency Sound
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound systems fail to effectively create a localized tactile and auditory experience for users by producing low-frequency sound waves that are optimally directed to the user while minimizing disturbance to others in the surrounding environment.
Innovation Solution
A speaker system with an open back design and venting mechanism that directs low-frequency sound energy directly to the user, creating a personalized plenum without enclosing the speaker's back, thereby reducing sound dispersion and energy waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the speaker back is enclosed in a speaker box, then sound energy is contained and directed forward, but sound energy is wasted and power consumption increases
Solution Approach 1:
The patent removes the traditional enclosed speaker box structure and extracts only the necessary functional elements. The speaker is mounted directly to a speaker support without a full enclosure, taking out the unnecessary enclosing structure while maintaining the core sound projection function. This eliminates the energy waste associated with enclosed designs while reducing structural complexity.
Solution Approach 2:
The patent segments the speaker system into distinct functional components: the speaker itself, the speaker support, and the front member with elongate open portion. This segmentation allows each component to perform its specific function efficiently without the need for a unified enclosed structure, reducing overall system complexity while maintaining acoustic performance.
2Object-affected harmful factors
If low frequency sound is produced to create tactile response, then auditory and tactile experience is enhanced, but sound dispersion disturbs others in the room
Solution Approach 1:
The patent applies local quality by creating a concentrated sound pressure zone through the elongate open portion positioned against the user's back. The sound energy is locally concentrated where needed (at the user's body) rather than dispersed throughout the room. This allows effective tactile and auditory experience for the individual user while minimizing disturbance to others in the surrounding environment.
Solution Approach 2:
The user's body acts as an intermediary medium that receives and transmits the low frequency sound waves. The sound waves travel through the air to the user's back, then through the body tissues, creating the tactile response. This intermediary approach allows the sound energy to be contained and utilized efficiently at the target location rather than dispersing freely throughout the room.
3Adaptability or versatility
If the speaker is positioned to direct sound at the user, then personalized audio experience is achieved, but the speaker structure becomes more complex
Solution Approach 1:
The elongate open portion serves multiple functions: it structures the sound output, positions the sound source relative to the user, and provides a mounting structure for the speaker. This multi-functional design achieves personalized sound delivery without requiring separate positioning mechanisms, thereby avoiding increased structural complexity.
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
The system provides a more impactful auditory and tactile experience for the user with reduced power consumption and minimal disturbance to others, optimizing sound delivery to the individual while conserving resources.
Implementation Method 1
Low frequency sound may produce both a tactile and auditory response from the body
Implementation Method 2
the combination of sound pressure, to provide both auditory and a tactile response
Implementation Method 3
A back of the speaker may not be enclosed in a speaker box, whereby sound energy emitted from the back of the speaker may be substantially free to travel away from the back of the speaker

AI summary
A sound system is shown in the form of a speaker with or without a speaker box. A front member may be used with a speaker support, with the speaker mounted to the speaker support, thus comprising a speaker assembly. The front member of the speaker assembly may include an elongate open portion with a top end and a bottom end and the speaker positioned adjacent to the elongate open portion between the top end and the bottom end. The speaker assembly may be coupled to a portion of the vehicle seat which is not obstructive to the positioning of a user in the vehicle seat. This combination may be used in a vehicle seat but also in a backpack, a chair, personal gaming seat, arcade gaming seat, gambling machine seat, bed, massage table or any other similar device.
