Vehicle Holder Sound Guiding Groove for Loudspeaker Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handheld electronic device vehicle holders do not effectively direct sound from the device's loudspeaker towards the user, resulting in poor sound quality and missed calls due to the sound output being directed away from the user.
Innovation Solution
A handheld electronic device vehicle holder with a sound guiding groove that positions the loudspeaker's sound outlet at the edge of the holder, allowing sound to be directed towards the user through protrudent edges and a soundproof member to concentrate and transmit sound waves effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the loudspeaker is disposed at the back of the handheld electronic device to meet lightness and slimness requirements, then the device volume is decreased, but the sound output direction is away from the user resulting in poor sound quality
Solution Approach 1:
The holder body acts as an intermediary structure between the loudspeaker and the user. It includes a sound guiding groove that extends from the loudspeaker placement area to the front edge of the holder, serving as a mediator to redirect sound waves from the back-mounted loudspeaker toward the user's direction, thus solving the contradiction between compact device design and effective sound delivery
Solution Approach 2:
The solution transitions from a direct linear sound output path to a three-dimensional sound guidance structure. The sound guiding groove creates a spatial pathway that redirects sound waves in a different direction (from backward output to forward-directed output), utilizing spatial dimensionality to resolve the directional conflict between loudspeaker placement and sound delivery
2Device complexity
If the sound outlet is directed away from the user in conventional holders, then the device structure is simple, but the sound volume and quality obtained by the user is poor
Solution Approach 1:
The holder body serves as a mediating structure that intercepts sound waves from the loudspeaker and redirects them toward the user. The sound guiding groove within the holder body acts as the specific intermediary mechanism, creating a controlled pathway that improves sound delivery without requiring modification to the handheld device itself
Solution Approach 2:
The holder structure provides its own sound guidance function through the integrated sound guiding groove, making the holder self-sufficient in improving sound quality. The groove structure automatically directs sound waves along its path to the front edge, eliminating the need for additional active components or complex mechanisms
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
Enhances sound quality by directing sound towards the user, increasing volume and clarity, addressing the issue of missed calls and poor sound reception in conventional holders.
Implementation Method 1
the sound outlet of the loudspeaker of the handheld electronic device is placed in the sound guiding groove to allow sounds produced from the handheld electronic device to be guided to the edge of the holding body through the sound guiding groove

AI summary
A handheld electronic device vehicle holder is used to hold a handheld electronic device having a loudspeaker. The handheld electronic device vehicle holder includes a holding body, and the holding body has a sound guiding groove extending to the edge of the holding body. When the handheld electronic device is place on the holding body, the sound outlet of the loudspeaker of the handheld electronic device is placed in the sound guiding groove. Then, sounds produced from the handheld electronic device are guided to the edge of the holding body through the sound guiding groove.
