Speaker Vibration Plate Layout to Prevent Audio Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional speaker systems with integrated tactile feedback suffer from audio distortion due to high-pressure environments caused by the interaction of the vibration device and acoustic driver, limiting immersive audio experiences.
Innovation Solution
A speaker system design where the vibration unit is positioned in front of the acoustic unit, with through holes in the vibration plate allowing sound to penetrate without obstruction, and a synchronized vibration mechanism to prevent additional air pressure, ensuring high-fidelity audio playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the vibration device is integrated into the speaker system, then the space is saved, but the audio output is distorted
Solution Approach 1:
The vibration device is separated from the acoustic driver by positioning the vibration plate in front of the acoustic unit, with through holes that segment the acoustic path. This allows the vibration function and acoustic function to coexist in the same space without interfering with each other's performance
Solution Approach 2:
The vibration plate with through holes acts as an intermediary structure between the vibration device and the acoustic driver. It allows sound waves to pass through while transmitting vibration to the user, mediating between the two functions without causing distortion
2Device complexity
If the vibration device and acoustic driver operate in a closed cabinet, then the structure is compact, but high-pressure environment limits diaphragm oscillation
Solution Approach 1:
The vibration plate is designed with through holes, creating a porous structure that allows air pressure to equalize between the front and back of the plate. This prevents high-pressure buildup in the closed cabinet while maintaining structural compactness
Solution Approach 2:
The vibration plate is positioned in front of the acoustic unit, creating a new spatial dimension for vibration transmission. This dimensional arrangement allows sound waves to pass through the vibration plate via the through holes, reducing pressure constraints while maintaining compact structure
3Object-generated harmful factors
If the vibration device generates vibration, then tactile feedback is provided, but additional air pressure is generated causing audio distortion
Solution Approach 1:
The through holes in the vibration plate allow air pressure generated during vibration to escape, preventing pressure buildup that would cause audio distortion while maintaining the tactile feedback function
Solution Approach 2:
The vibration plate serves as an intermediary that transmits vibration to the user through the bracket while its through holes allow sound waves to pass through unobstructed, separating the vibration transmission function from the acoustic function

AI summary
A speaker with a vibration system includes an acoustic unit, a vibration unit and a bracket. The vibration unit and the acoustic unit are mounted on the bracket, and the vibration unit is arranged in front of the acoustic unit. The vibration unit provides a vibration plate and a vibration component. The vibration component drives the vibration plate to generate vibration and transmits to the ear through the bracket. The vibration signal generated by the vibration plate is converted from the audio signal of the acoustic unit to can keep in sync with the sound emitted by the acoustic unit. The vibration is closer to the audio than the use of vibration motor, etc. In addition, the vibration unit is arranged in front of the acoustic unit, the vibration signal can be directly transmitted to the ear to the maximize sound and vibration output to the user.
