Solution Overview
Problem
Conventional vibration devices face the challenge of inhibited vibration when attempting to secure dustproofness and waterproofness, which hampers their functionality in devices like smartphones and touch panels.
Innovation Solution
A vibration device design featuring a touch panel, a vibrator, a frame, and a first connecting member that covers the space between the panel and the frame, utilizing a three-part structure with a thinner third member to minimize interference and enhance dustproofness and waterproofness while allowing for effective vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connecting member is used to cover the space between the operation panel and the frame to secure dustproofness and waterproofness, then dustproofness and waterproofness are improved, but vibration of the operation panel is inhibited
Solution Approach 1:
The connecting member is divided into three distinct members (first member, second member, and third member) with different thicknesses. The third member has a smaller thickness than the first and second members, creating a segmented structure that allows vibration transmission while maintaining sealing functionality.
Solution Approach 2:
Different parts of the connecting member have different thicknesses. Specifically, the third member has a smaller thickness than the first and second members, creating local variations in the structure. This local quality difference allows the connecting member to simultaneously provide sealing and vibration transmission capabilities.
2Ease of manufacture
If the connecting member has uniform thickness to simplify manufacturing, then ease of manufacture is improved, but vibration transmission is inhibited
Solution Approach 1:
The connecting member features non-uniform thickness distribution where the third member has a smaller thickness than the first and second members. This local quality variation optimizes vibration transmission while maintaining overall structural integrity and sealing functionality.
Solution Approach 2:
The thickness parameter of the connecting member is varied across different sections. The third member has a different (smaller) thickness compared to the first and second members, allowing the structure to balance manufacturing feasibility with vibration transmission requirements.

AI summary
A vibration device includes a touch panel, a vibrator that is arranged on the touch panel, a frame that is separated from at least a part of the touch panel and is arranged to surround the touch panel in a planar view, and a first connecting member that is arranged on the touch panel and the frame to cover a space between a part of the touch panel and the frame in a planar view and that connects the touch panel and the frame. Furthermore the first connecting member includes a first member positioned on the operation panel, a second member positioned on the frame, and a third member covering a space in a planar view. The thickness of the third member is smaller than those of the first and second members.
