Smart Eyeglass Temple Speaker Layout for Wider Diaphragm Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart wearable eyeglasses with rectangular eyeglass temples have smaller speaker units due to limited space, resulting in reduced volume and vibration area of the diaphragm, which compromises acoustic performance.
Innovation Solution
A smart wearable eyeglass temple design with a housing that allows a larger speaker unit by tilting the frame and magnet system, featuring a quadrilateral cross-section and chamfered magnet surfaces, enabling a larger diaphragm and magnet volume, and incorporating a sound hole and leakage hole to enhance acoustic performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the width of the eyeglass temple is reduced for comfort and aesthetics, then the size of the speaker unit is reduced, but the volume of the magnet and vibration area of the diaphragm are reduced
Solution Approach 1:
The patent changes the orientation of the speaker unit from a conventional alignment to a tilted arrangement where the diaphragm vibrates in a direction perpendicular to the traditional front-back axis. By rotating the vibration direction to a left-right orientation and tilting the speaker unit at approximately 45 degrees, the design utilizes unused spatial dimensions within the temple structure, allowing a larger magnet and diaphragm volume without increasing the temple's external width.
Solution Approach 2:
The speaker unit is positioned asymmetrically within the temple, with the magnet located in the rear portion and the diaphragm in the front portion, creating a tilted configuration rather than a symmetric front-to-back arrangement. This asymmetric placement optimizes the use of available space within the constrained temple width, enabling larger acoustic components while maintaining a compact overall profile.
2Volume of moving object
If the speaker unit is made larger to improve acoustic performance, then the volume and vibration area increase, but the width of the eyeglass temple must be increased
Solution Approach 1:
The patent reorients the speaker unit so that the diaphragm vibrates in a left-right direction rather than the conventional front-back direction. This dimensional change allows the magnet and diaphragm to be positioned at angles of approximately 45 degrees relative to the temple's longitudinal axis, effectively utilizing three-dimensional space within the temple structure without increasing its external width.
Solution Approach 2:
The speaker unit is designed with a tilted orientation that optimizes the vibration dynamics of the diaphragm. By positioning the diaphragm to vibrate perpendicular to the traditional axis and tilting the entire speaker unit, the design creates optimal acoustic pathways and vibration efficiency within the constrained space, allowing larger components without proportionally increasing the temple width.
