Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker systems face challenges in automatically adapting transmission and reception modes of wireless communication modules when switching between different source apparatuses, leading to instability in audio signal reception and transmission.
Innovation Solution
A speaker apparatus and its controlling method that automatically switch transmission and reception modes of the wireless communication module based on the connected source apparatus, allowing for seamless changes and stable audio signal handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the speaker apparatus uses a fixed transmission/reception mode for wireless communication, then the wireless communication module operates stably, but the system cannot automatically adapt when switching between different source apparatuses
Solution Approach 1:
The patent implements dynamic switching between transmission mode and reception mode based on the connection status of source apparatuses. The wireless communication module automatically adjusts its operating mode according to whether a source apparatus is connected, enabling the system to adapt to different scenarios (playing local content vs. receiving wireless audio) while maintaining stable communication in each state
2Adaptability or versatility
If the speaker apparatus automatically switches transmission and reception modes based on source apparatus connection, then adaptability improves, but system complexity increases
Solution Approach 1:
The speaker apparatus autonomously determines whether to switch between transmission and reception modes based on the connection status of source apparatuses. The system automatically detects connection changes and performs mode switching without requiring user intervention or complex external control, simplifying the overall system architecture while maintaining adaptability
3Ease of operation
If manual switching of transmission/reception modes is required, then system stability is maintained, but ease of operation deteriorates
Solution Approach 1:
The system continuously monitors the connection status of source apparatuses and uses this feedback information to automatically adjust the wireless communication mode. When a source apparatus is connected, the system switches to reception mode; when disconnected, it switches to transmission mode. This feedback-driven automatic adjustment simplifies operation while maintaining communication stability through context-appropriate mode selection

AI summary
A speaker apparatus includes a first wireless communicator connected with a first source apparatus to receive a first audio signal from the first source apparatus or connected with an external speaker apparatus to transmit the first audio signal to the external speaker apparatus; a second wireless communicator configured to be connected with a second source apparatus to receive a second audio signal from the second source apparatus; and a controller configured to control the first wireless communicator and the second wireless communicator. The controller controls the first wireless communicator to switch from a reception mode to a transmission mode to transmit the second audio signal to the external speaker apparatus in response to the second wireless communicator being connected with the second source apparatus.
