Bass Seat Module with Double-Sided Diaphragms for Vibration Offset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automobile sound modules mounted on doors or under chassis cause discomfort due to Z-directional vibrations and occupy space, resulting in poor listening experiences for drivers and rear passengers.
Innovation Solution
A bass automobile seat module with a speaker box embedded in the seat's mounting slot, featuring a double-sided sound module with opposing vibration diaphragms that transmit sound through the seat, reducing resonance and enhancing listening experience while freeing up door space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-sided sound production unit is used in the BOX module, then the structure is simple, but the Z-directional vibration increases causing driver discomfort
Solution Approach 1:
The patent applies inversion by using a double-sided sound production unit instead of a single-sided one. The sound module vibrates both the front diaphragm (facing the driver) and the rear diaphragm (facing away from the driver) in opposite directions. This counteracts the Z-directional vibrations that cause discomfort, while maintaining relatively simple structural complexity.
2Reliability
If the BOX module is mounted on the automobile chassis, then the sound production is effective, but it occupies space for rear passengers to stretch their feet
Solution Approach 1:
The patent relocates the BOX module from the traditional chassis-mounted position (horizontal plane occupation) to the seat bottom mounting slot (vertical plane utilization). By mounting the speaker box in the Z-direction under the seat, the design frees up horizontal foot space for rear passengers while maintaining effective sound production through the seat structure.
3Area of stationary object
If the BOX module is mounted on the door, then the space is utilized, but the storage space on the door is reduced
Solution Approach 1:
The patent moves the BOX module from door mounting (horizontal space utilization) to seat bottom mounting (vertical space utilization). The seat bottom mounting slot provides sufficient vertical space for the speaker box, thereby restoring door storage space while maintaining effective sound production through the seat structure and vibration diaphragms.
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 solution provides a comfortable listening experience by offsetting vibrations and optimizing space usage, allowing for improved sound production and reduced discomfort during use.
Implementation Method 1
the first vibration diaphragm and the second vibration diaphragm have opposite vibration directions within the same time
Implementation Method 2
By means of the double-sided sound module, resonance can be automatically offset
Implementation Method 3
the first vibration diaphragm located in the mounting slot transmits a sound through the seat and a sound production channel of the double-sided sound module
