Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional speakers have a short lifespan due to a weak vibrating membrane that is easily damaged, and they often fail to produce high-quality low-frequency sound, while multifunction vibrators coupled with resonance media suffer from unstable contact and potential damage during vibration.
Innovation Solution
An audio resonance vibrator with a rigid resonance medium, such as a metal or wood plate, and an elastic frame that houses a magnetic circuit unit and vibrating unit, where the elastic frame acts as a damper to restrict vibration amplitude and enhance low-frequency sound quality by synchronizing vibrations with the resonance medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a thin film vibrating membrane is used in conventional speakers, then the device can generate sound, but the lifespan is short due to easy damage and low-frequency sound quality is poor
Solution Approach 1:
The patent removes the traditional thin film vibrating membrane from the speaker system and replaces it with a resonance medium (such as a metal plate or glass plate). This extraction of the vulnerable component eliminates the primary source of damage while maintaining sound generation capability through resonance.
Solution Approach 2:
The patent changes the material parameters of the vibrating element from thin film to rigid materials like metal or glass plates. This parameter change increases strength and durability while the resonance characteristics of these materials provide improved low-frequency sound quality.
2Adaptability or versatility
If a multifunction vibrator is coupled with a resonance medium, then both audible and tactile sensations can be provided, but the contact relationship is unstable and the resonance medium may be damaged during vibration
Solution Approach 1:
The patent designs the vibrator to be nested within or integrated with the resonance medium in a stable configuration. The vibrating element is positioned such that it maintains consistent contact with the resonance medium throughout the vibration cycle, preventing instability and damage.
Solution Approach 2:
The patent incorporates cushioning or protective structures between the vibrator and resonance medium to prevent direct impact damage. This beforehand cushioning protects the resonance medium from damage during vibration while maintaining the necessary contact for sound generation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution extends the lifespan of the speaker by stabilizing the contact between the vibrator and resonance medium, improving low-frequency sound quality and durability, while maintaining effective sound generation.
Implementation Method 1
When the coil is electrified by alternating current, the magnetic circuit part and the coil generates an alternating magnetic field. By the interaction between the alternating magnetic field and the alternating current in the coil, the vibrating member is activated to move along a vibration direction for generating sound.
Implementation Method 2
an elastic frame that houses a magnetic circuit unit and vibrating unit, where the elastic frame acts as a damper to restrict vibration amplitude and enhance low-frequency sound quality
Implementation Method 3
The audio resonance vibrator 1 has an elastic frame 14 disposed on the surface of the resonant medium 2 and a bracket 11 supported by the elastic frame 14 corporately forming a housing having a receiving space 3. The housing accommodates a magnetic circuit unit 5 and a vibrating unit 4 therein... driving the resonant medium 2 to vibrate in a proper frequency range so as to generate sound
