Solution Overview
Problem
Existing acoustic devices for chairs, such as those used in gaming or automobile seats, often hinder concentration by applying unwanted vibrations during tasks that require focus, like driving or playing first-person shooter games, and fail to adjust sound pressure levels effectively based on user preferences and postures.
Innovation Solution
The acoustic device features a mounting system that allows for two operational modes: a first acoustic operation where sound pressure and vibration are applied to the seated person, and a second acoustic operation where the vibration is minimized, allowing the user to focus without significant vibration, achieved by adjusting the orientation of the speakers and their mounting positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If speakers are configured to apply vibration to the seated person, then sensory experience is enhanced, but concentration is hindered during tasks requiring focus
Solution Approach 1:
The speaker system is designed with dynamic configurability, allowing the orientation and operational mode of speakers to be changed based on user needs. The mounting device enables speakers to be repositioned between different layouts (first layout for vibration application, second layout for minimized vibration), and the system can switch between different acoustic operations (first acoustic operation for sensory experience, second acoustic operation for concentration), making the system adaptable to different tasks and user preferences
2Adaptability or versatility
If speakers are mounted in a fixed layout, then device complexity is reduced, but adaptability to different acoustic operations is limited
Solution Approach 1:
The mounting device is designed with multi-functionality, incorporating both a first mounting portion for securing speakers in the first layout and a second mounting portion for securing speakers in the second layout. This universal mounting structure allows the same speaker system to perform multiple acoustic operations (first acoustic operation for vibration, second acoustic operation for minimized vibration) without requiring separate dedicated mounting systems for each function
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables users to selectively experience vibrations or focus without them, maintaining optimal sound pressure levels and user comfort across different activities and postures, thereby enhancing the overall user experience.
Implementation Method 1
an electro-acoustic transducer is mounted opens near the head of a person seated in the seat. When the electro-acoustic transducer operates, its acoustic energy is delivered
Implementation Method 2
an electro-acoustic transducer is mounted opens near the head of a person seated in the seat. When the electro-acoustic transducer operates, its acoustic energy is delivered from the upper outlet to the vicinity of the person's head
Implementation Method 3
its acoustic energy is delivered from the upper outlet to the vicinity of the person's head, and the acoustic energy can provide sensor stimulus to the seated person by a pressure shock or a pressure wave

AI summary
An acoustic device includes: a chair; and a speaker attached to the chair, wherein the acoustic device is configured to select and set at least one of a first acoustic operation in which a sound pressure or vibration is applied to a seated person sitting in the chair by emitting sound from the speaker, or a second acoustic operation in which two speakers, each being the speaker, face each other with an interval therebetween, and diaphragms of the two speakers vibrate in a direction the two speakers face each other.
