Solution Overview
Problem
Conventional vehicle-mounted sounding devices face limitations in size due to limited mounting space, resulting in insufficient sound loudness and low-frequency response.
Innovation Solution
A sounding device design featuring a double-sided sounding module with a sound guiding channel and cavity system within an outer casing, where sound from the back side is directed through the channel and cavity to enhance loudness and low-frequency output via a sound outlet on the front side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the size of the sounding device is increased to improve sound loudness and low-frequency response, then the sound performance is improved, but the mounting space limitation is violated
Solution Approach 1:
The patent implements a nested structure where the sound guiding channel is integrated within the outer casing, and the cavity is formed between the outer casing and the sounding component. This nesting arrangement allows the sound guidance system to be compactly housed within the limited device volume, achieving enhanced sound performance without proportionally increasing the overall device size.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement by forming a cavity between the outer casing and the sounding component, and designing the sound guiding channel to traverse through the outer casing. This dimensional optimization allows efficient sound path routing within a compact footprint, improving sound loudness without requiring a larger device envelope.
2Power
If the size of the sounding device is increased to improve low-frequency response, then the bass performance is improved, but the mounting space constraint is violated
Solution Approach 1:
The sound guiding channel and cavity are nested within the outer casing structure, creating a compact low-frequency enhancement system that does not require additional external space. This integrated nesting allows the device to achieve improved bass response while maintaining a size suitable for vehicle mounting.
Solution Approach 2:
The patent employs vertical and lateral spatial arrangement within the outer casing to create an efficient sound path for low-frequency sounds. The cavity and sound guiding channel are positioned to optimize acoustic resonance and bass response within the constrained three-dimensional space, avoiding the need for a larger device volume.
3Power
If a sound guiding channel and cavity system is added to improve sound transmission, then the sound loudness is improved, but the device complexity is increased
Solution Approach 1:
The patent merges the sound guiding channel and cavity functions into the existing outer casing structure. The outer casing serves dual purposes: providing mechanical protection and housing the acoustic guidance system. This merging reduces the number of separate components and simplifies the overall device architecture while achieving improved sound transmission.
Solution Approach 2:
The outer casing is designed to perform multiple functions simultaneously: structural support, sound isolation, and sound guidance. By making the outer casing multi-functional, the patent avoids adding separate dedicated components for each function, thereby reducing device complexity while still achieving enhanced sound loudness through the integrated sound guiding channel and cavity system.
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

Implementation Method 1
one end of the sound guiding channel is communicated with the sound outlet hole, and the other end of the sound guiding channel is communicated with the cavity
Implementation Method 2
an outer casing located outside the sounding component for forming a cavity between the outer casing and the end of the sounding component close to the back side
