If a speaker is positioned close to surrounding electrical components to reduce device size, then the device becomes more compact, but magnetic force leakage degrades the performance of surrounding electrical components
Solution Approach 1:
A metal plate is introduced as an intermediary component between the speaker and surrounding electrical components. This metal plate acts as a magnetic shield that blocks magnetic force leakage from the speaker, preventing degradation of nearby electrical components while allowing the speaker to be positioned closely for compact device design.
Solution Approach 2:
The patent utilizes the magnetic properties of the metal plate to convert the harmful magnetic force leakage into a beneficial shielding effect. The metal plate redirects and contains the magnetic field, transforming what would be harmful interference into a controlled magnetic pathway that protects surrounding components while maintaining speaker proximity.
2Object-affected harmful factors
If a metal plate is added to shield magnetic force, then magnetic interference is reduced, but device complexity increases
Solution Approach 1:
The metal plate serves multiple functions simultaneously: it acts as a magnetic shield to block magnetic interference, provides structural support within the device assembly, and can serve as a mounting surface for other components. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
Solution Approach 2:
The shielding function is merged with the structural support function in a single metal plate component. By combining these functions, the patent avoids adding separate shielding structures and support elements, thus minimizing the increase in device complexity while still providing effective magnetic interference protection.
