Pivotable Driver Supporter for Vibrator Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional musical instruments face durability issues due to deformation of vibratable members like sound boards, which cause misalignment between the movable portion and the driver, leading to inappropriate electromagnetic engagement and vibration transmission, resulting in unstable operation and sound production.
Innovation Solution
A vibrator design that includes a driver supporter allowing the magnetic-path definer to be pivotable about an axis intersecting the movable direction, absorbing differences in angle and position caused by deformation or manufacturing errors, thereby maintaining appropriate electromagnetic engagement and improving durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the movable portion is secured to the vibratable member and the driver is secured to the support member, then the structure is simple and easy to manufacture, but the positional relationship between the movable portion and driver becomes inappropriate due to deformation or movement of the vibratable member, leading to lower durability
Solution Approach 1:
The driver supporter is designed to be pivotable about an axis extending in a direction intersecting the movable direction of the movable portion. This dynamic capability allows the driver supporter to adjust its position and maintain appropriate alignment between the movable portion and driver even when the vibratable member deforms or moves, thereby preventing inappropriate electromagnetic engagement and improving durability
Solution Approach 2:
The pivotable driver supporter changes its angular parameter dynamically to compensate for deformation or movement of the vibratable member. By allowing rotation about an axis intersecting the movable direction, the system adapts to positional changes and maintains optimal operational parameters for electromagnetic engagement
2Reliability
If the movable portion absorbs movement in the horizontal direction, then horizontal movement is compensated, but the difference in angle between the movable direction and the normal to the vibratable member cannot be absorbed, leading to excessive force generation
Solution Approach 1:
The driver supporter's pivotable design enables it to dynamically adjust its orientation by rotating about an axis that intersects the movable direction. This angular adjustment capability allows the system to absorb angle differences caused by vibratable member deformation, preventing excessive force generation while maintaining reliable positional stability
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
The pivotable driver supporter effectively maintains the positional relationship between the movable member and the magnetic-path definer, reducing excessive forces and ensuring stable vibration transmission and improved durability of the vibrating member.
Implementation Method 1
the movable portion is electromagnetically engaged with a magnetic-path definer (the driver) including a magnet and a core. When a current is applied to the coil of the movable portion, the movable portion vibrates

AI summary
A vibrator includes: a movable portion connected to a vibratable member; a driver configured to drive the movable portion to cause vibration of the movable portion to vibrate the vibratable member; and a driver supporter secured to a support member and configured to support the driver such that the driver is pivotable about an axis extending in a direction intersecting a movable direction of the movable portion.
