Stereo Microphone Pivoting Coupling and Supporting Bodies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stereo microphones for mobile devices are limited in their ability to capture stereo sound effectively in both portrait and landscape modes, requiring complex and delicate rotation mechanisms and occupying excessive space, making them difficult to use and maneuver.
Innovation Solution
A stereo microphone design featuring a coupling body and a supporting body that pivot about a single rotation axis, allowing easy repositioning between portrait and landscape modes, with resilient locking mechanisms to secure the transducer configuration, ensuring correct sound capture and user-friendly operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a spherical head with rotation mechanism is used to orient cartridges, then adaptability to different operating modes is improved, but device complexity increases
Solution Approach 1:
The microphone is divided into two separate bodies: a coupling body that connects to the mobile device and a supporting body that holds the transducer cartridges. These bodies can pivot relative to each other about a single rotation axis, allowing the cartridges to be oriented for different operating modes without requiring a complex spherical rotation mechanism. This segmentation simplifies the overall structure while maintaining adaptability.
2Adaptability or versatility
If a spherical head with separate cartridge rotation is used, then adaptability to different operating modes is improved, but ease of operation deteriorates
Solution Approach 1:
The controls and buttons for adjusting the microphone are integrated into the supporting body, which moves with the cartridges. This merging ensures that the controls remain in a consistent, easily accessible position relative to the user interface on the mobile device, eliminating the problem of controls becoming difficult to reach when the head is rotated. The user interacts with controls in a predictable location regardless of cartridge orientation.
3Adaptability or versatility
If a spherical head is used, then adaptability to different operating modes is improved, but volume increases
Solution Approach 1:
By separating the coupling body from the supporting body and using a single rotation axis instead of a spherical head, the overall volume of the microphone is reduced. The linear pivot mechanism requires less space than a spherical arrangement, making the microphone more compact while still enabling orientation adjustment for different operating modes.

AI summary
A stereo microphone for mobile devices, comprising a coupling body provided with elements for electromechanical connection to a mobile device and a supporting body for sound wave transducer means, which are integral therewith, the supporting body being pivoted to the coupling body by way of pivoting elements that allow its rotation about a single rotation axis for transition between a first shooting configuration, which corresponds to the use of the mobile device in portrait mode, and a second shooting configuration, which corresponds to the use of the mobile device in landscape mode.
