Speaker Second Ring-Shaped Body Low-Frequency Resonance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional speakers, such as flat panel speakers, primarily transmit tone quality to medium- and high-frequency sounds, with limited low-frequency transmission, resulting in poor sound performance and high manufacturing costs when attempting to improve low-frequency effects.
Innovation Solution
The speaker design incorporates a second ring-shaped body between the washer and the first ring-shaped body, connected to the groove's wall surface, enhancing low-frequency effects and peak power with reduced distortion, allowing for improved sound transmission across frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional speaker structures are used, then manufacturing cost is reduced, but low-frequency transmission capability deteriorates
Solution Approach 1:
The speaker structure is divided into multiple functional segments: the groove structure for low-frequency resonance, the tube for magnetic field generation, the first ring-shaped body for structural support, and the second ring-shaped body for enhanced low-frequency transmission. Each segment performs a specific function, allowing the system to achieve improved low-frequency capability without requiring a complete redesign of the entire speaker structure.
Solution Approach 2:
The invention introduces a vertical dimension by creating a groove that extends downward from the base surface, and places the magnet at the bottom of this groove. This three-dimensional arrangement allows the magnetic field to interact with air volumes in the vertical dimension, enhancing low-frequency resonance and transmission without increasing the horizontal footprint or requiring expensive external acoustic enclosures.
2Reliability
If outer structure is improved to enhance low-frequency effect, then low-frequency transmission capability is improved, but manufacturing cost increases
Solution Approach 1:
The groove structure serves multiple functions: it provides mechanical support for the magnet, creates a resonance chamber for low-frequency enhancement, and guides the magnetic field interaction. The first and second ring-shaped bodies simultaneously provide structural support and enhance acoustic transmission. This multi-functionality eliminates the need for separate, expensive acoustic enclosure components.
Solution Approach 2:
The speaker structure uses its own components (groove, magnet, ring-shaped bodies) to generate and enhance low-frequency sounds internally, without requiring external acoustic enclosures or additional passive radiators. The groove and ring-shaped bodies work together to create resonance and enhance low-frequency transmission using the existing magnetic field generation mechanism.
3Device complexity
If conventional speaker structures are used, then device complexity is reduced, but sound quality deteriorates
Solution Approach 1:
The invention enhances sound quality by optimizing specific local regions: the groove concentration at the bottom portion, the magnet placement in the groove, the first ring-shaped body positioned between the tube and washer, and the second ring-shaped body connected to the groove wall. Each local region is designed with specific properties to enhance its functional contribution to overall sound quality without requiring complex changes throughout the entire structure.
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 speaker effectively transmits tone quality across medium-, high-, and low-frequency sounds with improved sound sensitivity and reduced distortion, achieving enhanced sound quality without the need for costly outer structure modifications.
Implementation Method 1
Signals output from an amplifier are input to the coils 121, and the coil 121 generates a magnetic field that interacts with the magnet 11. As a result, the tube 12 moves back and forth relative to the magnet 11
Implementation Method 2
the driving surface 14a of the washer 14 upwardly drives the vibration plate 15 to vibrate the air and to make sound

AI summary
A speaker includes a base having a groove, a tube received in the groove, a magnet disposed in the tube, a first ring-shaped body and a washer mounted, from top to bottom, on an outer side of the tube sequentially, and a second ring-shaped body connected to an edge of the first ring-shaped body and installed around a wall surface of a rim of the groove. The second ring-shaped body has an inner ring-shaped plate, an outer ring-shaped plate, and a connection segment connected between the inner ring-shaped plate and the outer ring-shaped plate. Therefore, a low-frequency effect thus generated is greatly improved.
