Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the magnetic element is directly fixed to the outer frame, then the structural strength is improved, but the vibration transmission to the outer frame increases causing resonance and poor sound quality

Engineering Contradiction:
Improvestructural strengthVSAvoidvibration transmission
Core Design Contradiction:
StrengthVSObject-generated harmful factors

Solution Approach 1:

The patent introduces elastic members as intermediary components between the magnetic element and the outer frame. These elastic members serve as mediators that decouple the magnetic element from the outer frame, allowing the magnetic element to vibrate freely while preventing direct transmission of vibrations to the outer frame. This resolves the contradiction by maintaining structural connection through the elastic members while blocking harmful vibration transmission.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the harmful vibration transmission path by separating the magnetic element from the outer frame through the elastic members. The elastic members are positioned to isolate the magnetic element's vibrations from the outer frame, effectively removing the direct transmission path of harmful vibrations while maintaining the necessary structural relationship.

Inventive Principle:
Principle #2Taking out (Extraction)

2Object-generated harmful factors

If the magnetic element is suspended through elastic members, then the vibration transmission to the outer frame is reduced, but the structural stability decreases

Engineering Contradiction:
Improvevibration transmissionVSAvoidstructural stability
Core Design Contradiction:
Object-generated harmful factorsVSStability of the object's composition

Solution Approach 1:

The elastic members act as intermediaries that provide both vibration isolation and structural support. They maintain the magnetic element's suspension while absorbing vibrations, thus preserving structural stability without transmitting harmful vibrations to the outer frame.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent utilizes the elastic properties of the elastic members to change the mechanical parameters between the magnetic element and outer frame. The elastic members provide flexibility to absorb vibrations while maintaining sufficient structural connection, effectively changing the stiffness and damping parameters to achieve both stability and vibration reduction.

AI summary

The present invention provides a speaker structure and a speaker device. The speaker structure is connected with the magnetic carrier and the outer frame through the two elastic members. The four ends of the two elastic members are connected to the tour connection positions among the two lateral walls of the magnetic carrier and the bottom plate. When the magnetic element performs electromagnetic induction to make the voice coil and the vibration member vibrate to make sound, the magnetic element will be affected by the same reaction force to vibrate. In the meantime, the reaction force to vibrate received by the magnetic element is thus transmitted to the outer frame. Since the reaction force is mostly absorbed by the two elastic members, the affection from the reaction force to the outer frame is extraordinarily decreased as well, so as to the vibration member.
