Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling audio service interference, such as noise cancellation and automatic volume adjustment, are inefficient and costly, often requiring additional devices or increasing terminal power consumption, leading to reduced noise reduction effectiveness and shorter terminal lifespan.
Innovation Solution
A method using short-range wireless communication technologies like Bluetooth, Wi-Fi, or infrared to send interference control messages between terminals, allowing one terminal to adjust its settings to reduce noise interference without the need for additional devices, thereby conserving power and improving user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If noise cancellation method is used, then noise reduction effect is improved, but device complexity increases due to additional noise reduction device
Solution Approach 1:
The patent introduces a message as an intermediary carrier to transmit interference control parameters between terminals. Instead of direct noise cancellation hardware, the first terminal sends a message containing interference control parameters to the second terminal, which then adjusts its output accordingly. This message-based intermediary approach achieves noise reduction without adding complex cancellation devices.
Solution Approach 2:
The patent replaces the mechanical/acoustic noise cancellation system with an information-based control system. Rather than using acoustic waves to cancel noise physically, the system uses electronic messages to convey interference control parameters, which then trigger software-based or settings-based noise control on the second terminal.
2Object-affected harmful factors
If automatic volume adjustment method is used, then noise resistance is improved, but power consumption increases and terminal lifespan decreases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and transmitting interference control parameters before the audio service is affected by noise. The first terminal determines the appropriate control parameters in advance and sends them to the second terminal via message, allowing the second terminal to proactively adjust its settings rather than reactively increasing volume during noise events.
Solution Approach 2:
The patent changes the control parameter from volume level to interference control parameters that include play mode, volume level, and pause state. By transmitting these comprehensive parameters through a message, the system enables the second terminal to adjust multiple settings optimally rather than simply increasing volume, thereby reducing power consumption while maintaining noise resistance.
3Object-affected harmful factors
If automatic volume adjustment method is used, then noise resistance is improved, but terminal lifespan is reduced due to frequent volume adjustments
Solution Approach 1:
The system performs preliminary determination of interference control parameters and transmits them via message before noise interference occurs. This allows the second terminal to pre-adjust its audio output settings, avoiding the need for frequent reactive volume adjustments that would stress the terminal hardware and reduce lifespan.
Solution Approach 2:
The patent implements a feedback mechanism where the first terminal monitors the audio service execution state and surrounding noise conditions, then sends interference control parameters to the second terminal. This closed-loop feedback enables optimized, condition-based adjustments rather than frequent unconditional volume increases, reducing wear on the terminal.

AI summary
The present invention provides a method for controlling interference in an audio service and a terminal. The method includes: when executing an audio service, sending, by a first terminal, a first message by using a short-range wireless communications technology; determining, by a second terminal according to the first message, whether the second terminal supports interference control; and adjusting, by the second terminal, a setting of the second terminal according to the interference control parameter if the second terminal supports the interference control, and the second terminal falls within a controlled range. It can be learned that in a process in which the first terminal performs interference control on the second terminal, the first terminal may send the first message to the second terminal without a need of a noise reduction device, so that the second terminal adjusts the setting of the second terminal. This can be implemented easily without complex operations at low costs.
