Rotating Built-in Speaker for Wireless Audio and Lighting Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional built-in speakers installed in walls or ceilings require a separate audio device for sound output and lack the ability to operate independently, as they are fixed in place and dependent on external power and signal transmission.
Innovation Solution
A built-in audio apparatus with a mode setting unit that allows the speaker unit to be selectively positioned for power application and sound emission, featuring a controller, touch sensor for volume adjustment, and wireless communication for audio data transmission, enabling independent operation and integration with lighting control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the speaker unit is fixed in place within the structure, then the installation stability is improved, but the ability to control power application and sound emission is worsened
Solution Approach 1:
The speaker unit is made rotatable relative to the mode setting unit, allowing it to switch between a first position (recessed into the structure) and a second position (protruding from the structure). This dynamic positioning enables the speaker unit to be rotated into the second position for power application and sound emission, and into the first position for concealment, thus resolving the contradiction between installation stability and operational control.
2Shape
If the speaker unit is recessed into the structure for concealment, then the aesthetic appearance is improved, but the sound emission capability is worsened
Solution Approach 1:
The speaker unit can be rotated between a first position where it is recessed into the structure for aesthetic concealment, and a second position where it protrudes from the structure for effective sound emission. This dynamic repositioning allows the system to switch between aesthetic mode and functional mode as needed.
3Extent of automation
If the built-in audio apparatus operates independently with wireless communication, then the operational autonomy is improved, but the device complexity is worsened
Solution Approach 1:
The built-in audio apparatus integrates multiple functions including wireless communication for receiving audio data, a controller for autonomous operation and power management, a speaker unit for sound emission, and a mode setting unit for position control. This multi-functional integration enables operational autonomy while managing complexity through consolidation of functions within a single apparatus.

AI summary
A built-in audio apparatus includes a speaker unit, a mode setting unit configured to selectively set the speaker unit to one of a first position and a second position, and a controller configured to control the speaker unit depending on the setting of one of the first position and the second position. The mode setting unit is configured to be disposed in a surface of a structure, and includes an opening for emitting sound outputted from the speaker unit.
