Integrated Audio Door Assembly for Concealed Multi-Room Sound
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional solutions for achieving sound/speech privacy, intercom systems, auditory sleep therapy, and whole-home audio often require multiple, expensive, and complex installations, which may not fully satisfy all desires and can be inefficient due to limitations in insulation and visibility of electronics.
Innovation Solution
An audio door system that integrates an audio system, amplifier, and exciter within a door, allowing wireless audio streaming to transform electrical signals into mechanical energy, which is then converted into acoustic sound waves, providing multi-functional audio capabilities without visible wires or electronics, including speech privacy, intercom, sleep therapy, and background music across multiple zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional insulation and separate audio systems are installed, then sound privacy and audio functionality are achieved, but device complexity and installation cost increase
Solution Approach 1:
The patent combines the exciter, amplifier, and audio system into a single integrated door assembly. The exciter is mounted directly to the door surface, with the amplifier and audio system housed within the door structure, eliminating the need for separate wall-mounted speakers and reducing installation complexity while maintaining sound privacy functionality
Solution Approach 2:
The door assembly serves multiple functions: it provides sound privacy through its construction, acts as an audio output device through the exciter and amplifier, and functions as a structural element. This multi-functionality eliminates the need for separate audio equipment in each room, reducing overall system complexity
2Adaptability or versatility
If traditional loudspeakers are installed in walls and ceilings, then audio functionality is achieved, but aesthetic appeal and ease of installation deteriorate due to visible electronics and wiring
Solution Approach 1:
The patent extracts the audio output function from traditional wall/ceiling mounted loudspeakers and relocates it to the door assembly. The exciter is mounted on the door surface, allowing audio functionality to be achieved without visible electronics in walls and ceilings, thereby improving aesthetic appeal while maintaining versatility
Solution Approach 2:
The door itself serves as an intermediary surface that converts electrical audio signals into acoustic sound waves through the exciter. This eliminates the need for traditional loudspeaker enclosures and visible wiring, providing a clean aesthetic while maintaining full audio functionality across multiple rooms
3Adaptability or versatility
If multiple separate systems are installed for different audio needs, then specific audio functions are achieved, but loss of time and installation efficiency worsen
Solution Approach 1:
The door assembly is designed to provide multiple audio functions simultaneously - speech privacy, intercom, sleep therapy, and background music - all through a single installation. The amplifier and exciter can play different audio streams to different sides of the door or to multiple doors, eliminating the need for separate installations for each audio function and significantly reducing installation time
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
The audio door system effectively addresses multiple audio needs with a single installation, offering seamless audio streaming through various materials like sheetrock, insulation, and wood, providing comprehensive audio solutions while maintaining aesthetic appeal by concealing components.
Implementation Method 1
The exciter can transform an audio electrical signal into mechanical energy
Implementation Method 2
cause a surface of the door to transform the mechanical energy into one or more acoustic sound waves

AI summary
According to one example, an audio door system includes a door, an audio system, an amplifier, and an exciter. The audio system is coupled to the door. The amplifier is coupled to the door, and is electrically coupled to the audio system. The exciter is coupled to the door, and is electrically coupled to the amplifier. The exciter can transform an audio electrical signal into mechanical energy, and can further cause a surface of the door to transform the mechanical energy into one or more acoustic sound waves.
