Wireless Home Entertainment System with Bluetooth Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home entertainment systems require costly installation involving drilling, wiring, and wall construction, which damages the original decoration and poses safety hazards while achieving stereo surround sound.
Innovation Solution
A wireless home entertainment system connecting entertainment equipment with Bluetooth transmitters and speakers via wireless radio waves, eliminating the need for physical installation and using a control panel for audio control functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wired home entertainment system is installed, then stereo surround sound effect is achieved, but installation cost increases and original decoration is damaged
Solution Approach 1:
The patent replaces the mechanical wiring system with a wireless Bluetooth transmission system. The entertainment equipment connects to speakers through Bluetooth radio waves instead of physical wires, eliminating the need for drilling and wall construction while maintaining audio output functionality. This substitution resolves the contradiction by achieving surround sound without decoration damage.
Solution Approach 2:
The patent introduces a Bluetooth transmitter as an intermediary device between the entertainment equipment and speakers. This intermediary enables wireless audio transmission, allowing the system to achieve stereo surround sound effect without direct physical connections, thereby avoiding wall drilling and decoration damage.
2Device complexity
If wireless Bluetooth connection is used, then installation complexity and cost are reduced, but connection stability may be affected
Solution Approach 1:
The patent divides the audio system into independent modular units (entertainment equipment, Bluetooth transmitter, front speakers, rear speakers) that can be independently positioned and connected. This segmentation allows flexible wireless placement without complex wiring, reducing installation complexity while maintaining connection stability through dedicated Bluetooth pairs between each component.
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 system achieves 4-channel stereo surround sound efficiently and safely without damaging the original decoration, reducing costs and installation complexity.
Implementation Method 1
The Bluetooth transmitter (110) is simultaneously connected to the front speakers (130) and the rear speakers (120) through wireless radio waves

AI summary
The present invention relates to a home entertainment system, which includes four major parts: entertainment play equipment, a Bluetooth transmitter, a set of rear audio play devices, and a set of front audio play devices with a subwoofer.The rear audio play devices are composed of a main speaker, a sub-speaker, wire, and a Bluetooth receiver; the front Bluetooth speakers are composed of a main speaker, a sub-speaker, a subwoofer, wire, and a Bluetooth receiver, and each Bluetooth receiver is integrated in each main speaker.This home entertainment system uses a Bluetooth transmitter module to connect the entertainment play equipment with the rear speakers and the front speakers through wireless radio waves, and can simultaneously emit 4-channel audio of left front, left rear, right front, and right rear to achieve stereo surround sound effects. When the existing home entertainment audio is installed, it is necessary to drill, wire, and construct on the wall. That method is costly, and will destroy the original decoration and cause inconvenience. Therefore, we bring forward the home entertainment system.
