Wireless Speaker Sound Pressure Coordination for System Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In systems using multiple wireless speakers, controlling sound pressure individually can lead to imbalances, affecting overall sound quality and system stability.
Innovation Solution
A sound output control apparatus that transmits and receives setting information to synchronize sound pressure and frequency ranges across multiple wireless speakers, using a transmitter, receiver, and controller to adjust gain and frequency settings based on temperature, amplitude, and power supply conditions.

1Object-affected harmful factors
If control to suppress sound pressure is performed only with respect to a specified wireless speaker in a system using a plurality of wireless speakers, then the sound pressure of the specified speaker is reduced, but this results in an imbalance in sound in the overall system
Solution Approach 1:
The system divides the sound pressure control into two segments: individual speaker control (for suppressing excessive sound pressure) and system-wide coordination (for maintaining overall balance). Each wireless speaker independently monitors its own sound pressure and communicates with the control device, allowing simultaneous local suppression and global balance maintenance through segmented control architecture
Solution Approach 2:
The control device receives sound pressure information from each wireless speaker and sends back coordinated control instructions. This feedback loop ensures that when one speaker's sound pressure is suppressed, the control device adjusts other speakers accordingly to maintain overall system balance, preventing the imbalance problem
2Manufacturing precision
If gain is increased to improve sound output quality, then sound quality is improved, but temperature of the speaker increases and may cause damage
Solution Approach 1:
The system dynamically adjusts the gain of each wireless speaker based on real-time temperature conditions. When temperature exceeds thresholds, the gain is automatically reduced to prevent damage. This dynamic adjustment allows the system to maintain optimal sound quality when conditions permit while preventing overheating damage when temperature rises
Solution Approach 2:
The control device changes the operating parameters (gain values) of wireless speakers based on temperature measurements. By monitoring temperature and adjusting gain accordingly, the system maintains sound output quality within safe temperature limits, preventing speaker damage while preserving audio fidelity
3Productivity
If individual wireless speakers are controlled independently for optimal performance, then each speaker performs well, but the overall system sound balance deteriorates
Solution Approach 1:
The system merges individual speaker control with system-wide coordination through a central control device. Each speaker maintains its optimal performance settings while the control device combines information from all speakers and sends coordinated adjustments to maintain overall sound balance. This merging of individual and collective control resolves the contradiction between individual performance and system balance

AI summary
The present technology relates to a sound output control apparatus and a sound output control method that perform control to prevent a balance of a system from being disturbed when reproduction is performed using a plurality of wireless speakers. A sound output control apparatus includes a transmitter that transmits first setting information regarding a sound output of the sound output control apparatus, a receiver that receives second setting information regarding a sound output of another sound output control apparatus, and a controller that controls a sound pressure or a reproduction frequency range in which reproduction is performed, on the basis of the first setting information or the second setting information. The first setting information and the second setting information each include at least information regarding a temperature, information regarding an amplitude, information regarding a remaining capacity of a power supply, and/or information regarding the reproduction frequency range.
