Headset Speaker Shell Layout for Radial Battery Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional headsets with large batteries for extended endurance result in a bulky design, occupying internal space and making the headset thick, which is inconvenient for wearing and use.
Innovation Solution
A headset design with two headset units, each containing a battery and circuit board, where the batteries are arranged side by side in a radial direction, reducing volume and thickness by utilizing the mounting chamber efficiently, and incorporating a speaker shell with angled mounting surfaces to optimize space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a large-sized battery is used to ensure sufficient capacity and long endurance, then the battery capacity is improved, but the headset unit becomes thicker and occupies more internal space
Solution Approach 1:
The patent divides the single large battery into two smaller batteries, each housed in separate headset units. This segmentation allows the batteries to be arranged side by side in the radial direction rather than stacking in the thickness direction, thereby reducing the thickness of each headset unit while maintaining sufficient total battery capacity for long endurance
Solution Approach 2:
The patent changes the arrangement dimension from vertical stacking (thickness direction) to horizontal placement (radial direction). By utilizing the radial space within the headset unit housing, the batteries are positioned side by side, which reduces the thickness dimension while effectively using available internal volume
2Quantity of substance
If a large-sized battery is stacked inside the headset unit shell with other electronic components, then sufficient battery capacity is achieved, but the overall structure becomes thicker and less comfortable for wearing
Solution Approach 1:
The patent segments the single large battery into two smaller batteries distributed across separate headset units. This segmentation enables better spatial distribution of components, allowing the headset units to have a more compact and ergonomic design that is thinner and more comfortable for wearing, while the combined capacity of both batteries maintains sufficient power supply
Solution Approach 2:
The patent transitions from stacking components in the thickness direction to arranging them in the radial direction. This dimensional change allows for more efficient space utilization within the headset unit housing, reducing overall thickness and improving wearing comfort while accommodating all necessary components including batteries, circuit boards, and speaker assemblies

AI summary
A headset comprises a headband and two headset units connected to two ends of the head band respectively. Each of the two headset units comprises a headset housing, a speaker shell, an ear cap, and a battery. At least one of the two headset units further comprises a circuit board. The ear cap is connected to the headset housing in the one of the two headset units. A surface of the speaker shell in the one of the two headset units fits with an inner wall surface of the headset housing to enclose a mounting chamber. The surface of the speaker shell is formed with a first mounting surface and a second mounting surface. The first mounting surface is connected to the battery in the one of the two headset units, and the second mounting surface is connected to the circuit board.
