Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices require separate installations for speakers and vibrators, leading to a cumbersome manufacturing process and significant occupancy of interior space.
Innovation Solution
A multifunctional sounding device that combines speaker and vibrator functions by incorporating a frame with a vibrator assembly and a speaker assembly, where the vibrator assembly includes a vibrating unit suspended in the frame and the speaker assembly features two magnetic units, a diaphragm, and voice coils, allowing for simultaneous sound emission and vibration provision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate speaker and vibrator are installed individually, then each component can perform its dedicated function, but the manufacturing process becomes cumbersome and interior space is significantly occupied
Solution Approach 1:
The patent combines the speaker and vibrator into a single integrated sounding device that shares a common frame, magnetic units, and voice coils. This merging eliminates the need for separate installations of individual speaker and vibrator components, simplifying the manufacturing process while reducing the total volume occupied in the electronic device.
Solution Approach 2:
The integrated sounding device performs multiple functions simultaneously - it can emit sounds through the diaphragm and provide vibrations through the vibrating unit, both through the same voice coils and magnetic units. This multi-functionality allows one component to replace what would traditionally require two separate components.
2Adaptability or versatility
If separate speaker and vibrator are installed, then functional independence is maintained, but device complexity increases
Solution Approach 1:
The patent integrates the speaker and vibrator functions into a single device with shared components including the frame, magnetic units, and voice coils. This reduces installation complexity by eliminating separate mounting procedures while maintaining the ability to independently control sound emission and vibration functions through the shared voice coil system.
