Microphone Boom Locking Mechanism for Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional microphone stands cause arm soreness in staff due to the need to maintain a fixed hand position to keep the microphone pole suspended at a certain angle during prolonged filming scenarios.
Innovation Solution
A limiting structure with a mounting component, support component, and locking component that allows for adjustable and lockable positioning of the microphone boom, enabling flexible adjustment and secure fixation of the microphone angle without constant hand support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If staff hold the stand pole with both hands to position the microphone near the subject, then the microphone can be positioned correctly, but staff experience arm soreness during prolonged filming
Solution Approach 1:
The stand is divided into two separate poles: a support pole for structural support and a microphone pole for positioning the microphone. This segmentation allows the support pole to bear the weight and provide stability while the microphone pole can be adjusted independently, reducing the physical burden on staff during prolonged use
Solution Approach 2:
The support pole acts as an intermediary between the staff and the microphone pole. By attaching the support pole to the staff's backpack, it mediates the support function, allowing the staff to hold only the lightweight microphone pole with one hand while the heavier support structure is carried separately
2Ease of operation
If staff wear a backpack with the support pole to hold one end of the stand pole with one hand, then the workload is reduced, but staff still need to maintain a fixed hand position to keep the microphone pole suspended at a certain angle
Solution Approach 1:
The connection between the support pole and microphone pole is made dynamic through a locking mechanism that allows the microphone pole to be adjusted to different angles and then locked in place. This dynamic system enables the pole to transition between movable (for positioning) and fixed (for maintaining angle) states, eliminating the need for continuous manual adjustment while providing flexibility when needed
3Reliability
If the microphone pole is adjusted to a specific angle for good recording, then the recording quality improves, but staff must maintain a fixed hand position continuously
Solution Approach 1:
The locking mechanism allows staff to perform preliminary positioning of the microphone pole at the desired angle for optimal recording, then lock it in place. This preliminary action followed by locking eliminates the need for continuous manual maintenance of the position, as the pole remains fixed at the pre-adjusted optimal angle throughout the recording process

AI summary
This application pertains to the field of photographic equipment technology and introduces a limiting structure, a support mechanism, and an audio stand. The limiting structure encompasses a mounting component, a support component, and a locking component. The mounting component serves to install a microphone boom; the support component is movably connected to the mounting component; one end of the locking component connects to the support component, while the other end connects internally within the mounting component to secure or release the support component and the mounting component. The locking component facilitates a loose and a locked condition between the mounting component and the support component. When rotated to achieve the loose condition, the mounting component can shift relative to the support component, allowing the microphone boom mounted on it to be adjusted to a suitable angle relative to the support component. Following adjustment, the locking component can be rotated to establish the locked condition between the mounting component and the support component, thereby fixing the microphone boom at the adjusted angle.
