True Wireless Multichannel Speakers Energy Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing true wireless multichannel-speakers devices consume excessive energy when generating sound effects independently, leading to battery depletion and limited customization options, with user experience compromised by continuous noise and limited natural sound effects.
Innovation Solution
A true wireless multichannel-speakers device comprising a first and second sounder, each equipped with a sound effect generator, provider, and speaker, connected via wireless transceivers, allowing independent sound effect generation and synchronization of output timelines using control value sets and synchronous control signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If sound effects are generated from one sounding end and transmitted to the other, then sound effect output is achieved, but energy consumption increases and battery power becomes insufficient
Solution Approach 1:
The patent divides the sound effect generation function into separate segments for each sounding end. Each sounder (first sounder and second sounder) independently generates its own sound effects locally rather than one end generating and transmitting to the other. This segmentation eliminates the need for wireless transmission of audio data between devices, significantly reducing energy consumption and preserving battery power while maintaining the ability to output natural sound effects independently.
2Use of energy by moving object
If sound effects are stored on respective sounding ends, then energy consumption is reduced, but customization options are limited and user interaction becomes difficult
Solution Approach 1:
The patent implements a dual-mode system where each sounder can function independently with locally stored sound effects (conserving energy) or connect wirelessly to a host device for expanded sound effect libraries and customization options. The sound effect value provider can receive control values from either local storage or external sources, enabling the system to adapt between energy-saving independent operation and versatile customized operation based on user needs.
3Productivity
If limited natural sound effects are continuously played, then sound effect output is maintained, but user experience is disturbed by noise and repetition
Solution Approach 1:
The patent implements timeline synchronization that coordinates the periodic playback of sound effects between multiple sounders. The synchronizer manages the timing and sequencing of sound effect generation across different channels, ensuring that natural sound effects are distributed and alternated properly over time. This periodic coordination prevents continuous repetition of the same sounds, reduces noise disturbance, and maintains an immersive natural environment experience.

AI summary
A true wireless multichannel-speakers device and a multiple sound-source voicing method thereof are disclosed. The true wireless multichannel-speakers device includes a first and a second sounder. The first and the second sounders respectively include a first and a second sound effect generators, a first and a second sound effect value providers, and a first and a second speakers. The first sound effect value provider provides a first sound effect control value set to the first sound effect generator to generate a first sound effect output signal so that the first speaker outputs the first sound effect output signal. The second sound effect value provider provides a second sound effect control value set to the second sound effect generator to generate a second sound effect output signal so that the second speaker outputs the second sound effect output signal.
