Movable Drone Speaker for Dynamic Sound Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional unmanned aerial vehicles equipped with speakers do not effectively impart a sense of presence to listeners, as they lack the ability to dynamically position sound sources in accordance with the content's spatial information.
Innovation Solution
A speaker system comprising a first fixed speaker and a second movable speaker, where the first speaker emits sound signals corresponding to ambient or static sound sources, and the second speaker, equipped with a moving body, emits sound effects while moving to positions indicated by position information within the content, creating a more immersive audio experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed speaker system is used, then the system structure is simple and stable, but the sense of presence and immersion for the listener is insufficient
Solution Approach 1:
The speaker system is divided into a fixed first speaker and a movable second speaker (drone), allowing different functional roles. The first speaker provides stable ambient sound while the second speaker delivers dynamic sound effects, resolving the contradiction by segmenting the system into fixed and movable components.
Solution Approach 2:
The second speaker is designed to move dynamically based on position information from the content, transforming from a static to a dynamic system. This enables the sound source to relocate in sync with the content, enhancing the sense of presence while maintaining overall system stability through the fixed first speaker.
2Reliability
If a movable speaker is added to enhance sound localization, then the sense of immersion is improved, but the device complexity increases
Solution Approach 1:
The system segments sound output into two categories: ambient sound from the fixed first speaker and sound effects from the movable second speaker. This segmentation allows precise sound localization for effects while keeping the overall system manageable through clear functional division.
Solution Approach 2:
The movable second speaker serves multiple functions: it provides sound effects, enhances spatial audio positioning, and creates immersive experiences. By consolidating these functions into a single movable unit rather than adding multiple fixed speakers, the system achieves high sound localization accuracy without excessive complexity.
3Reliability
If the second speaker moves to different positions, then the sound source localization is enhanced, but the control complexity increases
Solution Approach 1:
The control system receives position information from the content as feedback and automatically adjusts the second speaker's position accordingly. This feedback mechanism enables accurate sound source positioning without requiring complex manual control, as the system autonomously responds to position data from the audio content.
Solution Approach 2:
The second speaker autonomously navigates to the correct positions based on embedded position information in the content, without requiring external real-time control. The speaker system self-adjusts its configuration to match the content requirements, reducing control complexity while maintaining accurate sound source positioning.

AI summary
A speaker system includes a first speaker and a second speaker. The first speaker includes a first sound signal input interface configured to acquire a first sound signal, and a first sound emitter configured to output a first sound based on the first sound signal in a state in which a position of a host device is fixed. The second speaker includes a second sound signal input interface configured to acquire a second sound signal, a moving body that includes a position information acquisition interface configured to acquire information relating to position and that is configured to move based on the information relating to position, and a second sound emitter configured to output a second sound based on the second sound signal.
