Solution Overview
Problem
The independent design of speaker and motor structures in electronic devices, such as smartphones and smartwatches, limits the internal space and hinders overall performance improvement due to inefficient spatial arrangement.
Innovation Solution
A structural design integrating a weighting base with a hollow frame and a bearing plate, along with a magnetic unit and voice coil configuration, allows for a thinner form factor and closer positioning of motor and speaker components, enhancing magnetic field strength and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If speaker structure and motor structure are independently designed and separately installed, then each component can be optimized individually, but the internal space occupied increases and structural layout is restricted
Solution Approach 1:
The patent combines the speaker structure and motor structure into a single integrated assembly. The voice coil serves dual functions as both the speaker actuator and motor coil, the magnetic unit provides magnetic field for both speaker vibration and motor vibration, and the vibration component acts as both speaker diaphragm and motor vibration element. This merging eliminates the need for separate speaker and motor components, thereby reducing the internal space occupied while maintaining individual component optimization through the unified design.
2Adaptability or versatility
If speaker structure and motor structure are independently designed, then each component can function independently, but the overall performance improvement is hindered due to space limitations
Solution Approach 1:
The integrated structure employs universal components that perform multiple functions. The voice coil generates electromagnetic force for both speaker sound production and motor vibration. The magnetic unit creates the magnetic field necessary for both speaker operation and motor actuation. The vibration component serves as both the speaker diaphragm for sound emission and the motor vibration element for haptic feedback. This multi-functionality enables both components to operate independently while maximizing overall device performance within limited space.
3Ease of manufacture
If separate speaker and motor structures are used, then installation is straightforward, but the structural arrangement of internal space is restricted
Solution Approach 1:
By merging the speaker and motor structures into a single integrated assembly, the patent reduces the number of separate components that need to be installed and arranged within the device. The unified structure with shared components (voice coil, magnetic unit, vibration component) simplifies the structural arrangement of internal space while maintaining ease of manufacture through standardized assembly processes.
