Speaker Antenna Layout for LTE Interference in Hinged Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with hinged or detachable housings, the overlap of antenna and speaker components can lead to degradation of antenna performance due to radio wave reflection, especially with LTE communication antennas, which require secure antenna performance for effective wireless communication.
Innovation Solution
The antenna and speaker components are positioned at a predetermined distance from each other, and the housings are partially or entirely formed of non-metal materials to minimize interference, ensuring that the antenna performance is maintained even in tablet mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the antenna portion and speaker portion are arranged close to each other or overlapping in tablet mode, then the device can be made thinner, but radio waves may be reflected on metal components of the speaker and antenna performance may be degraded
Solution Approach 1:
The patent extracts the speaker from the second housing and positions it on the first housing, separating the speaker from metal components that would cause radio wave reflection. This allows the antenna and speaker to be close or overlapping in tablet mode without degrading antenna performance, as the speaker is no longer surrounded by metal housing components.
Solution Approach 2:
The patent implements a nested arrangement where the first housing (containing the antenna) and second housing (containing the keyboard) overlap in tablet mode, with the speaker positioned on the first housing within this nested structure. This allows thin profile while maintaining antenna performance through proper spatial arrangement.
2Adaptability or versatility
If a communication antenna for LTE is mounted, then wireless communication capability is enhanced, but antenna performance tends to be degraded more easily due to wide frequency band and long transmission distance
Solution Approach 1:
The patent extracts the speaker from its conventional position within the second housing surrounded by metal components, and relocates it to the first housing. This separation removes the harmful influence of metal components on radio waves, thereby protecting LTE antenna performance in the wide frequency band and long transmission distance scenarios.
Solution Approach 2:
The patent uses the first housing structure as an intermediary positioning platform for the speaker, placing it on the outer surface of the first housing rather than within the second housing. This intermediary positioning allows the speaker to be integrated into the device while minimizing its negative impact on antenna performance.

AI summary
According to one embodiment, an electronic device includes a first housing including an antenna for wireless communication, and a second housing including a speaker for audio output configured to be used in a state where the second housing overlaps the first housing. When the antenna and the speaker are seen through from an upper surface side of the first housing, a location of the antenna and a location of the speaker do not relatively overlap each other.
