Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices, such as mobile phones, face challenges in providing both high-quality audio and vibration tactile experiences due to the separate installation of loudspeaker and motor devices, leading to increased space occupation and unsatisfactory layout effects.
Innovation Solution
A sound production device is designed to integrate a loudspeaker and a motor within a single housing, utilizing a vibration module with a coil and a vibrator assembly, and a loudspeaker module with a vibration system and magnetic circuit system, allowing for synchronous vibration and sound production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a loudspeaker device and a motor device are provided separately, then the audio experience and vibration tactile experience functions are achieved, but the space occupation in smart terminal devices increases
Solution Approach 1:
The patent combines the loudspeaker device and motor device into a single integrated sound production device. The housing contains both the vibration module (with coil and vibrator assembly) and the loudspeaker module (with vibration system and magnetic circuit system), allowing both audio and vibration functions to be achieved within one compact structure, thereby reducing the overall space occupation in smart terminal devices
Solution Approach 2:
The integrated sound production device serves multiple functions simultaneously: it acts as both a loudspeaker for audio output and a motor for vibration tactile feedback. The housing and internal components are designed to support both functions, making the device universal and eliminating the need for separate dedicated components
2Reliability
If a loudspeaker device and a motor device are provided separately, then the audio experience and vibration tactile experience functions are achieved, but the layout effect becomes unsatisfactory
Solution Approach 1:
By merging the loudspeaker and motor into a single integrated unit with unified housing and coordinated internal layout, the patent achieves a more compact and aesthetically pleasing arrangement. The components are positioned to optimize both functionality and spatial efficiency, improving the overall layout effect compared to separate devices
