Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electroacoustic transducers with curved diaphragms lack optimal design and acoustic characteristics, failing to meet diverse consumer preferences and requiring improved performance in both design and sound reproduction.
Innovation Solution
An electroacoustic transducer featuring a vibrating body with longitudinally divided cylindrical surfaces, supported by a frame and housed within a chamber, where the actuator converts electrical signals into vibrations or vice versa, allowing the vibrating body to cover the housing and extend around its exterior, providing a smooth integral design and enhanced acoustic performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the vibrating body is separated from the housing in existing speakers, then the external appearance becomes standardized, but the design property deteriorates and cannot meet diverse consumer preferences
Solution Approach 1:
The vibrating body is designed to extend to and connect with the exterior surface of the housing, merging previously separate components into an integrated structure. This eliminates the standardized appearance while enabling diverse design configurations that match consumer preferences.
Solution Approach 2:
The vibrating body extends beyond the traditional planar diaphragm configuration into three-dimensional space, wrapping around or connecting to the housing exterior. This dimensional expansion creates new design possibilities while maintaining acoustic functionality.
2Reliability
If conventional curved diaphragm structures are used, then basic speaker function is achieved, but acoustic characteristics utilizing the curved shape are not optimized
Solution Approach 1:
The vibrating body incorporates curved surfaces that extend to the housing exterior, utilizing the curvature to optimize sound radiation patterns and acoustic characteristics while maintaining reliable speaker function.
Solution Approach 2:
Different portions of the vibrating body have differentiated functions: the central portion provides primary vibration while the peripheral portions extending to the housing contribute to sound diffusion and acoustic optimization, creating locally optimized performance.
3Adaptability or versatility
If the vibrating body extends to connect with the housing exterior, then design property and acoustic characteristics are improved, but the structure becomes more complex
Solution Approach 1:
The vibrating body serves multiple functions simultaneously: it acts as the acoustic diaphragm, the exterior design element, and the connecting structure between components. This multi-functionality reduces overall structural complexity despite the extended configuration.

Function Achieved in This Case
The solution results in an electroacoustic transducer with improved acoustic characteristics and design properties, minimizing diffracted waves and standing waves, and offering a seamless integration of the vibrating body and housing, enhancing both sound radiation and visual appeal.
Implementation Method 1
The actuator is connected to the vibrating body, in particular connected to where the first pair of longitudinally divided cylindrical surfaces meet, and is configured to convert one of an electrical signal into vibration of the vibrating body or vibration of the vibrating body into an electrical signal

AI summary
An electroacoustic transducer, which can be a speaker or a microphone, includes a frame, a housing, and a vibrating body having one or more vertically split cylindrical faces. The opposing sides of the vibrating body is connected to the housing or the frame. A conversion section converts an electrical signal into vibration of the vibrating body or vibration of the vibrating body to an electrical signal. The vibrating body can extend to the side surfaces of the housing or completely wrap around the housing.
