Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate speaker and vibrator are installed, then sound emission and vibration functions are achieved, but device complexity and interior space occupancy increase
Solution Approach 1:
The patent combines the speaker and vibrator into a single integrated unit. The vibration assembly serves dual purposes: it vibrates along a first direction to emit sounds and along a second direction (perpendicular to the first) to provide vibrations. This merging eliminates the need for separate installations, reducing manufacturing complexity while maintaining both sound emission and vibration functions.
Solution Approach 2:
The integrated sounding device achieves multi-functionality by enabling the same structural components to perform multiple functions. The vibration assembly and magnetic assembly work together to produce both acoustic output and haptic feedback, allowing a single device to replace what would traditionally require separate speaker and vibrator components.
2Adaptability or versatility
If separate speaker and vibrator are installed, then sound emission and vibration functions are achieved, but interior space occupancy increases
Solution Approach 1:
By merging the speaker and vibrator into one integrated unit with shared components (vibration assembly, magnetic assembly, driving coil), the patent significantly reduces the total volume required in the electronic device. The perpendicular vibration directions are achieved within the same spatial footprint, eliminating the need for separate spaces for individual speaker and vibrator installations.
Solution Approach 2:
The patent utilizes perpendicular vibration directions (first direction for sound, second direction perpendicular to first for haptic feedback) to achieve multi-functionality within the same spatial plane. This dimensional approach allows both sound emission and vibration provision without requiring additional interior space.
3Device complexity
If integrated speaker and vibrator are combined, then manufacturing complexity and space occupancy are reduced, but structural integrity must be maintained
Solution Approach 1:
The integration is achieved through a unified structure where the vibration assembly, magnetic assembly, and driving coil form a cohesive unit. The magnetic assembly includes a main magnet and auxiliary magnet with a magnetic gap, and the driving coil is positioned to interact with both magnets, creating a stable integrated structure that maintains structural integrity while simplifying manufacturing.
Solution Approach 2:
While integrating components, the patent uses segmentation to divide the housing into functional regions. The housing includes a top wall, bottom wall, and side wall with specific recessed portions that accommodate different components (driving coil in first recessed portion, elastic member in second recessed portion), maintaining structural organization and integrity.

AI summary
Disclosed is a multifunctional sounding device which combines functions of emitting sounds and providing vibrations and includes a housing; a speaker unit including a vibration assembly vibrating along a first direction and a magnetic assembly including a main magnet and an auxiliary magnet; an elastic member suspending the speaker unit in the housing; a flexible sealing membrane assembly connected between the housing and the speaker unit including an outer ring, an inner ring, and a flexible sealing membrane connected between the two rings; and a driving coil driving the speaker unit for vibrating in a second direction including two sides respectively facing the main magnet and the auxiliary magnet in the first direction. The two directions are perpendicular. The outer ring, the flexible sealing membrane and the inner ring are integrally formed, thereby achieving a high structural consistency and avoiding glue width requirements so as to release spaces.
