Adjustable Ear Cup Shaper for Eyewear Accommodation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional headsets often fail to accommodate eyewear comfortably, leading to gaps between the headset and the wearer's head that affect audio quality, particularly reducing the perceived loudness of low-frequency audio.
Innovation Solution
The headset incorporates adjustable ear cup shapers, such as straps or plungers, that create space for temple pieces of eyeglasses, and includes sensors to detect the configuration of these shapers. The headset's audio processing circuit adjusts audio settings, like bass boost, based on the detected configuration to maintain optimal audio quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional headsets are designed to fit tightly against the head for good audio quality, then audio quality is improved, but eyewear cannot be accommodated comfortably
Solution Approach 1:
The ear cup shaper is made adjustable with multiple configurations (e.g., straps that can be tightened or loosened, plungers that can be positioned at different depths) allowing the headset to dynamically adapt its shape. This enables the headset to transition between a tight seal configuration for optimal audio and a configured state that accommodates temple pieces of eyeglasses, resolving the contradiction between audio quality and eyewear accommodation.
Solution Approach 2:
The physical parameters of the ear cup shaper (such as the depth of a plunger or the tightness of a strap) can be changed to create different amounts of depression or space in the ear cup. By varying these parameters, the headset can accommodate different types of eyewear while maintaining the necessary seal for audio quality, thus resolving the technical contradiction.
2Ease of operation
If ear cup shaper creates space for eyewear to accommodate temple pieces, then eyewear accommodation is improved, but air gaps are created that reduce perceived loudness of low-frequency audio
Solution Approach 1:
Sensors detect the configuration of the ear cup shaper (e.g., whether the plunger is extended or the strap is tightened) and provide feedback to the audio processing circuit. Based on this feedback, the audio processing circuit dynamically adjusts audio settings such as bass boost to compensate for any air gaps created by the shaper configuration, thereby maintaining audio quality while accommodating eyewear.
Solution Approach 2:
The audio processing circuit changes audio parameters (such as frequency response or gain) based on the detected shaper configuration. When the shaper creates space for eyewear, the system detects this and adjusts the audio output to compensate for potential air gaps, ensuring consistent audio quality across different eyewear configurations.
3Adaptability or versatility
If adjustable ear cup shaper with sensors and audio processing is added to accommodate eyewear, then eyewear accommodation is improved, but device complexity increases
Solution Approach 1:
The adjustable ear cup shaper serves multiple functions: it accommodates eyewear temple pieces, maintains the seal for audio quality, and provides a mechanism for the sensors to detect user configuration. The audio processing circuit also serves multiple functions by processing audio signals and dynamically adjusting settings based on sensor feedback. This multi-functionality reduces the need for separate components, thereby managing complexity while achieving versatility.

AI summary
A headset comprises an ear cup, at least one speaker, an adjustable ear cup shaper, and circuitry. The ear cup shaper is adjustable into at least two configurations, wherein a first of the configurations creates no depression or a first amount of depression in the ear cup and a second of the configurations creates a second amount of depression in the ear cup, where the second amount is greater than the first amount. The circuitry is operable to determine which one of the configurations the ear cup shaper is configured into, and set an audio setting applied to an audio signal output to the speaker based on the determined one of the configurations.
