Flexible Speaker Arrangement for Dynamic Audio Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices face limitations in producing high-quality audio due to fixed speaker configurations, which fail to adapt to the type of audio content, leading to inadequate loudness and sound quality, especially when playing stereo content on mono or dual speakers.
Innovation Solution
A method and apparatus that analyze audio data to identify the optimal angle for bending sides of a flexible electronic device, adjusting the speaker arrangement to match the type of audio content, thereby optimizing sound output by dynamically configuring the speaker positions based on the audio data analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed speaker configuration is used in mobile devices, then the device structure remains simple and compact, but the audio quality and loudness are insufficient for different types of audio content
Solution Approach 1:
The patent implements a flexible display structure that can dynamically change its shape between flat and bent states. The speaker configuration adapts dynamically based on the display shape: when the display is flat, speakers are arranged in a first configuration; when bent, they switch to a second configuration. This dynamic adaptability allows the same physical speaker components to serve different audio content types (stereo, mono, surround) without adding permanent structural complexity.
Solution Approach 2:
The system changes the spatial parameters of speaker arrangement based on display shape parameters. When the display bending angle changes, the relative positions and orientations of the speakers change accordingly. This parameter coupling allows the speaker configuration to adapt to different audio content requirements without requiring independent control mechanisms for each speaker.
2Reliability
If multiple speakers are added to improve audio quality, then the loudness and sound fidelity improve, but the device size and weight increase
Solution Approach 1:
The patent makes the existing speaker components multi-functional by changing their spatial arrangement rather than adding dedicated speakers for each audio mode. The same physical speakers can produce stereo sound, mono sound, or surround sound effects depending on their relative positions and orientations, which are adjusted according to the display shape. This eliminates the need for separate speaker sets for different audio content types.
Solution Approach 2:
Instead of having fixed multiple speakers for all audio modes, the system dynamically configures the speaker arrangement based on the actual audio content being played and the display shape. This allows the device to achieve high-quality audio output comparable to multiple fixed speakers while using fewer physical speaker components, thereby reducing overall device weight.
3Adaptability or versatility
If the speaker arrangement is fixed, then the manufacturing process is simple, but the speaker configuration does not match the audio content type
Solution Approach 1:
The patent couples the speaker arrangement parameters with the display shape parameters. When the display is manufactured with specific bending capabilities, the speaker mounting positions are designed to automatically achieve optimal configurations based on the display's bent or flat state. This parameter coupling is built into the manufacturing design, allowing the speakers to self-configure without complex assembly processes or additional adjustment mechanisms.
Solution Approach 2:
The speaker mounting structure is pre-designed with hinge connections and adjustable mechanisms that allow the speakers to be positioned in optimal configurations for different display shapes. This preliminary design of the mounting system enables easy reconfiguration during assembly or use, without requiring complex manufacturing processes for each specific speaker arrangement.
