Conference Call Volume Adjustment via Device Count Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conference calls where multiple devices are used by participants in close proximity, the summation of voice volumes often results in excessive play volume, causing discomfort to participants.
Innovation Solution
A method and system where a host device detects the number of connected sub-devices and adjusts the volume of voice signals according to a predetermined volume threshold, ensuring that the voice signals played or collected by each device remain within a tolerable range by either decreasing the volume to the threshold or proportionally adjusting it based on the decibels of the sub-devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple calling devices are used in close proximity for conference call, then the conference call capability is enhanced, but the voice volume becomes excessive due to summation effect
Solution Approach 1:
The patent dynamically adjusts the voice signal parameters (volume level) based on the number of calling devices detected. When multiple devices are detected, the system automatically reduces the volume parameter of the voice signal to prevent excessive summation effect, while maintaining the conference call functionality.
Solution Approach 2:
The system implements a feedback mechanism by detecting the number of connected calling devices and using this information to adjust the voice volume. The detection result feeds back to the volume control module, which then modifies the output volume accordingly to maintain comfortable listening levels.
2Reliability
If voice volume is increased for better audibility, then the voice can be heard more clearly, but it causes discomfort to participants due to excessive volume
Solution Approach 1:
The system dynamically changes the volume parameter based on the number of devices detected. By calculating the appropriate volume level according to device count, the system ensures voice signals remain clearly audible while preventing excessive volume that would cause participant discomfort.

AI summary
A method and a system for adjusting a volume of a conference call are provided. The system includes at least one sub-device and a host. The host respectively connects the at least one sub-device and detects a number of the connected sub-devices. The host adjusts a volume of an original voice signal received from an external device according to the number of the connected sub-devices to generate an adjusted voice signal adapted to each sub-device and provides the same to each sub-device to play. The host also adjusts volumes of the original voice signals received by the host and each sub-device, integrates the adjusted original voice signals into an integrated voice signal adapted to the external device, and provides the same to the external device to play.
