Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If audio signal processing is applied based on speaker position and orientation, then audio quality is improved, but device complexity increases due to additional sensors and processing requirements
Solution Approach 1:
The patent applies multi-functionality by using existing sensors (accelerometer, gyroscope, proximity sensor, camera) for multiple purposes. These sensors originally serve other functions in the device but are repurposed to detect speaker position and orientation for audio equalization, avoiding the need for dedicated additional hardware while achieving improved audio quality.
Solution Approach 2:
The system performs self-service by automatically detecting the speaker's position and orientation using the device's own sensors, and automatically applying appropriate equalization settings without requiring manual user input or external calibration equipment. The device uses its existing computational resources to process sensor data and adjust audio output in real-time.
2Measurement precision
If multiple sensors are used to determine device position and orientation, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent leverages existing multi-functional sensors already present in modern electronic devices. The accelerometer and gyroscope serve both motion tracking and speaker positioning functions, the proximity sensor detects both user proximity and surface contact, and the camera captures both images and depth information for orientation detection. This approach achieves high measurement precision without adding dedicated single-purpose components.
Solution Approach 2:
The system merges multiple sensor data streams (accelerometer, gyroscope, proximity sensor, camera) into a unified position and orientation detection framework. By combining information from these diverse sensors, the system achieves more accurate and robust spatial awareness than any single sensor could provide alone, while utilizing existing hardware resources efficiently.

AI summary
Embodiments are provided for receiving a request to output audio at a first speaker and a second speaker of an electronic device, determining that the electronic device is oriented in a portrait orientation or a landscape orientation, identifying, based on the determined orientation, a first equalization setting for the first speaker and a second equalization setting for the second speaker, providing, for output at the first speaker, a first audio signal with the first equalization setting, and providing, for output at the second speaker, a second audio signal with the second equalization setting.
