Audio Device Sliding Baffle for Versatile Sound Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio devices have a single audio playback effect and are unable to meet the diverse requirements of various scenarios, such as smart watches, smart bracelets, AR devices, VR devices, and neck-mounted speakers.
Innovation Solution
An audio device with two sound generation units, each with separate front and rear cavities, and a sliding baffle that switches the sound generation combination between the front and rear cavities, allowing for different sound effects by controlling the opening and closing of sound holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single sound generation unit is used, then the device structure is simple, but the audio playback effect is single and cannot meet diverse scenario requirements
Solution Approach 1:
The sound generation unit is segmented into first and second sound generation units, each with independent front and rear cavities. This segmentation allows different sound generation combinations to be implemented, enabling diverse audio playback effects while maintaining a relatively simple overall structure.
Solution Approach 2:
A sliding baffle is introduced to dynamically switch between different sound generation combinations. The baffle can move to connect either the front cavities or rear cavities to sound holes, allowing the device to adapt between different audio playback modes (stereo, mono, bass enhancement) based on scenario requirements.
2Adaptability or versatility
If multiple sound generation combinations are provided, then diverse audio playback effects can be achieved, but the device structure becomes complex
Solution Approach 1:
The first and second sound generation units are designed with identical front and rear cavity structures, making them multi-functional. Each unit can independently contribute to different audio effects (stereo separation, mono summation, bass enhancement), allowing the device to achieve diverse playback effects without requiring fundamentally different structural components.
Solution Approach 2:
The sliding baffle acts as an intermediary element that controls the connection between cavities and sound holes. Instead of creating complex separate pathways for different audio modes, the baffle mediates the sound transmission by selectively opening or blocking pathways, simplifying the overall structural design while enabling multiple audio playback effects.

AI summary
Disclosed are an audio device and an intelligent wearable device. The audio device includes: a housing in which a first sound generation unit and a second sound generation unit are disposed, each of the first sound generation unit and the second sound generation unit has a front cavity and a rear cavity separated from each other, and the housing is provided with a first front sound hole in communication with the front cavity of the first sound generation unit, a second front sound hole in communication with the front cavity of the second sound generation unit, and a rear sound hole in communication with the rear cavity of the second sound generation unit. The audio device further includes a sliding baffle, wherein the sliding baffle is slidable between a first position and a second position with respect to the housing, and the sliding baffle is provided with a hole.
