Directional Speaker Audio Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with speakers lack the ability to automatically adjust audio settings to suit different audience sizes and distances, limiting their adaptability for various usage scenarios.
Innovation Solution
Incorporating a directional speaker and a non-directional speaker within the device, along with a processor that determines the appropriate audio configuration based on the target space, allowing for selection between these speakers to tailor audio transmission to specific audience types and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single non-directional speaker is used, then the device structure is simple, but the audio cannot be directed to specific target spaces
Solution Approach 1:
The audio output system is segmented into multiple independent speakers (first speaker and second speaker) that can be controlled separately. Each speaker can be independently activated based on the target space requirements, allowing directional audio control without requiring a completely complex system.
Solution Approach 2:
The system dynamically switches between different speaker configurations based on the detected target space. The processor determines which speakers to activate based on real-time conditions, making the system adaptable rather than static. This allows the same hardware to provide different audio behaviors (directional vs. omnidirectional) as needed.
2Adaptability or versatility
If multiple speakers are added for different target spaces, then audio adaptability improves, but the device complexity increases
Solution Approach 1:
The same speaker hardware is made multi-functional by controlling which speakers are activated based on the target space. The first and second speakers can serve different purposes (directional vs. omnidirectional audio) depending on the mode, allowing a single physical system to perform multiple audio functions without requiring separate dedicated systems.
Solution Approach 2:
The system automatically determines which speakers to activate based on the detected target space without requiring manual intervention. The processor self-regulates the speaker configuration based on conditions, reducing the need for user involvement in managing system complexity.
3Measurement precision
If directional speakers are used for small target spaces, then audio precision improves, but the system cannot serve large audiences
Solution Approach 1:
The system transitions from a static speaker configuration to a dynamic one where the processor adapts the active speakers based on the target space size. For small target spaces, the first speaker provides precise directional audio. For large target spaces, the second speaker provides omnidirectional coverage. This dynamic adaptation allows the system to maintain precision when needed while accommodating large audiences when necessary.
Solution Approach 2:
The system changes the operational parameters of the audio output by switching between different speakers with different radiation patterns. This parameter change (from directional to omnidirectional) allows the same physical system to optimize for different scenarios - precision for small audiences and coverage for large audiences.

AI summary
Implementations disclosed herein relate to transmitting audio in a target space relative to an electronic device using a directional speaker and non-directional speaker. In one implementation, a directional speaker or non-directional speaker is selected to transmit audio based on a target space for the audio. The audio may then be transmitted from the selected speaker.
