Coaxial Speaker Sound Guide for Multi-Directional Treble Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coaxial speakers emit sound in a single direction due to the alignment of the woofer and tweeter diaphragms, limiting sound propagation.
Innovation Solution
A coaxial speaker design where the woofer assembly generates bass sound in one direction and the treble sound from the tweeter assembly is guided by a sound guide portion to propagate in a different direction, allowing for sound emission in at least two main directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the woofer and tweeter diaphragms are aligned along the same axis with the same motion direction, then the coaxial speaker structure is simple and compact, but the sound propagation is limited to a single direction
Solution Approach 1:
The speaker system is segmented into two independent sound propagation paths: the woofer diaphragm generates sound that propagates in the first direction (frontal), while the tweeter diaphragm generates sound that propagates in the second direction (side or rear). This segmentation allows each component to have a dedicated propagation path, achieving multi-directional sound emission without requiring complex integrated structures.
Solution Approach 2:
The invention transitions from single-direction (one-dimensional) sound propagation to multi-directional (two or three-dimensional) sound propagation by introducing a second propagation direction that is different from the first direction. This dimensional expansion allows sound to be emitted both frontally and to the side/rear, significantly improving spatial audio coverage.
2Adaptability or versatility
If the woofer and tweeter are arranged coaxially with the same motion direction, then the manufacturing process is simple, but the sound dispersion is limited
Solution Approach 1:
The sound dispersion function is segmented between the woofer and tweeter components. The woofer is designed to primarily disperse sound in the first direction (frontal), while the tweeter is designed to primarily disperse sound in the second direction (side/rear). This functional segmentation achieves improved overall sound dispersion without requiring complex manufacturing processes, as each component maintains its traditional simple structure.
Solution Approach 2:
The coaxial speaker structure maintains universality by using the same basic coaxial arrangement and mounting mechanisms for both the woofer and tweeter, while achieving multi-directional sound dispersion through the differential design of their diaphragm motion directions. This allows the system to maintain ease of manufacture while improving sound dispersion performance.
3Adaptability or versatility
If the woofer and tweeter diaphragms move in the same direction, then the acoustic coupling is simple, but the sound coverage is limited to a single direction
Solution Approach 1:
The acoustic coupling is segmented into two independent pathways: the woofer diaphragm creates acoustic pressure waves that propagate in the first direction, while the tweeter diaphragm creates acoustic pressure waves that propagate in the second direction. This segmentation allows each diaphragm to be acoustically coupled to its respective propagation path independently, achieving comprehensive sound coverage without complex acoustic interference management.
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 design enables sound propagation in multiple directions, enhancing sound dispersion and avoiding the limitation of single-direction emission found in conventional coaxial speakers.
Implementation Method 1
The treble sound, generated by the tweeter assembly with the primary propagation direction along the first direction, is guided by the sound guide portion to propagate in a second direction
Data Source
AI summary
A coaxial speaker includes a tweeter assembly, a woofer assembly, and a frame. The tweeter assembly is used to generate treble sound with a primary propagation direction along a first direction. The woofer assembly is used to generate bass sound with a primary propagation direction along the first direction. The woofer assembly includes a sound guide portion, which faces the tweeter assembly. The treble sound generated by the tweeter assembly, having a primary propagation direction along the first direction, is guided by the sound guide portion to propagate in a second direction. The tweeter assembly and woofer assembly are coaxially arranged, and the second direction is different from the first direction. The tweeter assembly and woofer assembly are mounted on the frame.
