Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional loudspeakers lack vibration damping and isolation, leading to discomfort during operation, and have low production yield and rated power due to direct vibration transmission.
Innovation Solution
A vibration damping loudspeaker design featuring a sound-generating unit, magnetic member, assembly-auxiliary frame, and dampers that are easily assembled, with dampers acting as a buffer between the sound-generating unit and magnetic member to absorb and prevent kinetic energy transmission, enhancing vibration damping and isolation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional loudspeaker structure without dampers is used, then the device complexity is low and assembly is simple, but vibration damping and isolation are insufficient causing user discomfort
Solution Approach 1:
The patent introduces dampers as intermediary elements positioned between the magnetic member and the speaker base. These dampers serve as vibration isolation mediators that absorb and dissipate kinetic energy, preventing direct transmission of vibrations to the speaker base and subsequent transmission to the electronic device casing. This intermediary approach effectively resolves the contradiction by adding minimal structural complexity to achieve significant vibration damping improvement.
Solution Approach 2:
The dampers are pre-installed between the magnetic member and speaker base before assembly, creating a cushioning layer that anticipates and absorbs vibration energy before it can be transmitted to the speaker base. This beforehand cushioning mechanism prevents the harmful vibration transmission without requiring complex active control systems, thus resolving the contradiction between vibration isolation and device complexity.
2Object-affected harmful factors
If dampers are added between the speaker base and magnetic member, then vibration damping is improved, but assembly complexity increases
Solution Approach 1:
The patent merges the damper installation with the existing speaker base and magnetic member assembly process. The dampers are positioned and secured as integral parts of the assembly, combining multiple functions (vibration damping, structural support, and positioning) into a single assembly operation. This merging approach maintains ease of manufacture while achieving effective vibration damping.
Solution Approach 2:
The dampers serve multiple functions simultaneously: vibration damping, kinetic energy absorption, structural cushioning, and positioning elements. By making the dampers multi-functional, the patent reduces the need for separate components and simplifies the overall assembly process, thereby maintaining ease of manufacture while achieving comprehensive vibration isolation.
3Power
If the loudspeaker operates at high rated power, then sound output is improved, but vibration intensity increases causing more discomfort
Solution Approach 1:
The patent converts the harmful high-intensity vibrations generated at high rated power into beneficial effects by using the dampers to absorb and dissipate this kinetic energy. The vibration energy that would otherwise cause discomfort is transformed into thermal energy through the dampers' damping material, converting the harmful high-power vibrations into harmless heat, thus enabling high rated power operation without user discomfort.

AI summary
A vibration damping loudspeaker includes a sound-generating unit, a magnetic member, an assembly-auxiliary frame and dampers. Aligning units of the assembly-auxiliary frame are coupled to positioning units of the sound-generating unit. The dampers are symmetrically disposed between the magnetic member and the assembly-auxiliary frame. The sound-generating unit and the magnetic member can be quickly and easily mounted in place because of the assembly-auxiliary frame to not only enhance the production yield of the vibration damping loudspeaker but also allow the dampers to function as a buffer between the sound-generating unit and the magnetic member, so as to achieve vibration damping and vibration isolation during the operation of the vibration damping loudspeaker to spare users the discomfort they will otherwise experience for using electronic devices.
