Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the magnetic circuit system is suspended in the accommodation space with the help of the spring plate, then the speaker can achieve vibration function, but the structural stability deteriorates and the speaker is prone to drop-related damage
Solution Approach 1:
The patent applies preliminary anti-action by designing a protective structure that prevents drop damage before it occurs. The magnetic circuit system is positioned and constrained within the frame structure with specific spacing and support mechanisms that prevent collision with the rear cover during accidental drops, thereby counteracting the harmful effects of drops before they can cause damage.
2Adaptability or versatility
If the magnetic circuit system is suspended with spring plate, then the speaker achieves multifunctionality, but the service life deteriorates due to structural instability
Solution Approach 1:
The patent implements beforehand cushioning by creating a protective spatial arrangement where the magnetic circuit system is positioned at a specific distance from the rear cover and supported by the spring plate mechanism. This pre-configured protective structure cushions the magnetic circuit system against impact forces during accidental drops, thereby extending the service life while maintaining multifunctionality.
3Ease of operation
If the magnetic bowl and magnetic body component form a magnetic gap, then the speaker achieves sound production function, but the structural stability deteriorates
Solution Approach 1:
The patent applies local quality by optimizing the local structural characteristics of the magnetic circuit system. The magnetic bowl is designed with specific geometric features and the magnetic body component is positioned to create an optimized magnetic gap configuration. This localized structural optimization maintains the sound production function while improving the overall structural stability of the magnetic circuit system within the frame.

AI summary
A multifunctional speaker includes a frame with an accommodation space; a magnetic circuit system suspended in the accommodation space by the spring plate; a spring plate connected with the frame, one end of the spring plate being fixed at the frame, the other end of the spring plate being fixed at the side wall; and a annular rear cover attached to an end of the frame. The magnetic circuit system includes a magnetic bowl and a magnetic body supported by the magnetic bowl. The magnetic bowl includes a baseplate fixedly connected with the magnetic body and a side wall formed by bending from an edge of the baseplate. A gap is formed between the periphery of the baseplate and the annular rear cover, and the gap has a width between 0.05 and 0.20 mm.
