Rotating Speaker Driver for Omnidirectional Sound
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional speaker drivers are limited in their ability to produce omnidirectional sound and require a complex structure to cover the full range of high, mid, and low tones, necessitating multiple drivers.
Innovation Solution
A speaker driver design featuring a pair of yoke members with empty spaces, mounted magnets, and a rotating member with a voice coil and diaphragm, allowing for omnidirectional sound output with a simple structure that covers the entire tone range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional speaker driver structure is used, then the structure is simple, but it can only output sound in a specific direction and cannot achieve omnidirectional sound
Solution Approach 1:
The speaker driver is divided into multiple independent sound output units, each capable of producing sound in a specific direction. These segmented units work together to achieve omnidirectional sound coverage while maintaining a relatively simple overall structure.
Solution Approach 2:
The speaker driver structure is designed to perform multiple functions: it can output sound in multiple directions simultaneously and cover the entire frequency range (high, mid, and low tones) using a single driver unit, eliminating the need for separate tweeters, mid-range drivers, and woofers.
2Adaptability or versatility
If multiple speaker drivers are used to cover high, mid, and low tones, then the full range sound is achieved, but the structure becomes more complex
Solution Approach 1:
A single speaker driver unit is designed to perform multiple functions by incorporating the ability to produce high, mid, and low tones within one driver, eliminating the need for separate tweeters, mid-range drivers, and woofers that would otherwise be required to cover the full frequency range.
Solution Approach 2:
The functions of multiple speaker drivers (tweeter, mid-range driver, woofer) are merged into a single speaker driver unit, which integrates the capabilities to produce all frequency ranges in one unified structure, thereby simplifying the overall system.
3Adaptability or versatility
If sound absorbing agents are used to direct sound in a specific direction, then directional sound output is achieved, but omnidirectional sound output becomes difficult to implement
Solution Approach 1:
Instead of using sound absorbing agents to block sound in certain directions and allow sound to propagate in a specific direction, the invention inverts the approach by using multiple sound output units that actively produce sound in all directions simultaneously, achieving omnidirectional sound without relying on sound absorption or blocking mechanisms.
