Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The sound pickup effect of microphones in terminal devices, such as mobile phones, deteriorates when the device is far from the user or in noisy environments, leading to poor audio and video recording quality.
Innovation Solution
A sound pickup method using Bluetooth peripherals that adjusts sound effect processing dynamically based on device type or model through preset sound effect DRC parameters, enhancing sound quality by using different DRC parameters for different Bluetooth devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal device uses its built-in microphone to pick up sound, then the sound pickup effect is good when the photographed person is close to the device, but the sound pickup effect deteriorates when the photographed person is far away or environmental noise is excessive
Solution Approach 1:
The terminal device integrates multiple sound pickup paths (built-in microphone and Bluetooth peripheral microphone) into a unified system. The system can automatically or manually switch between different microphones based on the scenario, making the sound pickup system universally applicable to both close-range and far-range scenarios, as well as noisy and quiet environments.
Solution Approach 2:
The system dynamically adjusts the sound pickup path by switching between the built-in microphone and Bluetooth peripheral microphone based on real-time conditions. The terminal device can detect distance and noise levels, then dynamically select the optimal microphone source, or allow manual switching based on user needs, making the system adaptable to changing scenarios.
2Measurement precision
If the terminal device uses a single sound effect processing parameter for all Bluetooth devices, then the system complexity is reduced, but the sound effect quality cannot be optimized for different Bluetooth device types or models
Solution Approach 1:
The system applies different sound effect processing parameters to different Bluetooth device types or models. By identifying the specific Bluetooth device being used, the terminal device can select and apply tailored sound effect parameters optimized for that device's characteristics, thereby improving sound effect quality for each specific device type or model.
Solution Approach 2:
The system changes sound effect processing parameters based on the identified Bluetooth device type or model. Different parameter sets are prepared for different device categories, and the system automatically selects the appropriate parameter set, enabling optimized sound processing without requiring complex manual configuration.

AI summary
This application provides a sound pickup method for a terminal device through a Bluetooth peripheral and a terminal device. The terminal device may pick up sound data through a microphone of the Bluetooth peripheral, and may perform targeted sound effect processing on the sound data picked up by the Bluetooth peripheral by using a preset sound effect DRC parameter corresponding to the Bluetooth peripheral. By using the solution in this application, the terminal device may not only pick up sound through the Bluetooth peripheral, but also perform sound effect processing for different Bluetooth peripherals by using different preset sound effect DRC parameters respectively, to improve the sound effect of the sound picked up through the Bluetooth peripheral, so that a better recording effect can be achieved even if the terminal device is relatively far away from a photographed person or environmental noise surrounding the terminal device is relatively large.
