Speaker Enclosure Antenna Layout to Prevent Overlap and Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of integrating high-performance speakers and wireless communication antennas into miniaturized electronic devices is significant, as they often overlap and interfere with each other, leading to noise and vibration issues, and limited internal mounting space.
Innovation Solution
The integration of a speaker-integrated antenna system where the first and second antenna patterns are spaced apart and electrically coupled on separate cases of the speaker enclosure, preventing overlap with the speaker unit and allowing for improved antenna efficiency and additional internal space for components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a speaker and antenna are integrated in a miniaturized electronic device, then the device size is reduced and internal space is saved, but noise and vibration increase due to overlap and interference between components
Solution Approach 1:
The speaker enclosure is divided into a first case and a second case, with antenna patterns disposed on different surfaces of each case. This segmentation separates the antenna components from the speaker unit, reducing interference while maintaining integration benefits.
Solution Approach 2:
Antenna patterns are arranged in three-dimensional space on different surfaces and orientations of the speaker enclosure cases, rather than placing all components in a single plane. This spatial arrangement reduces overlap between speaker and antenna while maintaining compact overall dimensions.
2Volume of stationary object
If antenna patterns are disposed on speaker enclosure surfaces, then additional internal space is created for mounting components, but antenna efficiency may be reduced due to potential overlap with speaker units
Solution Approach 1:
Antenna patterns are selectively disposed on specific surfaces of the speaker enclosure cases where they will not overlap with the speaker unit. The first antenna pattern is on a first surface of the first case, and the second antenna pattern is on a second surface of the second case, optimizing both space utilization and antenna performance.
3Object-affected harmful factors
If the speaker enclosure is spaced apart from the housing, then noise and vibration are reduced, but the internal space for mounting the speaker is reduced
Solution Approach 1:
The speaker enclosure is integrated with antenna patterns on its surfaces, combining the speaker and antenna functions into a single assembly. This merging allows the speaker to be spaced from the housing for noise reduction while the antenna utilizes the enclosure surfaces, maintaining compact overall device dimensions.
