Detachable TV Speaker System with Dual Wired Wireless Audio Modes

Solution Overview

Problem

Conventional TV speakers are integrally manufactured with the TV, making them non-separable and limiting communication with mobile devices and audio output to specific modes.

Innovation Solution

A system comprising a detachable main speaker and sub speaker capable of wire/wireless communication, automatically detecting attachment or separation to output audio signals in different modes and enable bi-directional communication with external mobile devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If TV speaker is integrally manufactured with TV, then structural stability is improved, but communication capability with mobile devices and audio output versatility deteriorate

Engineering Contradiction:

Improvestructural stabilityVSAvoidcommunication capability and audio output versatility

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The speaker system is divided into separate components: a main speaker unit and detachable sub speaker units. This segmentation allows the sub speakers to be independently attached or detached, enabling flexible communication modes (wired when attached, wireless when detached) and multiple audio output configurations, thereby resolving the contradiction between structural stability and adaptability.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If TV speaker is separable from TV set, then adaptability is improved, but communication capability with mobile devices deteriorates

Engineering Contradiction:

ImproveadaptabilityVSAvoidcommunication capability with mobile devices

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The sub speaker units are designed with dual functionality: they can operate in wired mode when attached to the main speaker and in wireless mode when detached. This multi-functionality ensures that communication capability with mobile devices is maintained regardless of the attachment state, while still providing adaptability through detachable design.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If sub speaker is detachably attached to main speaker, then adaptability is improved, but device complexity increases

Engineering Contradiction:

ImproveadaptabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The speaker system is divided into separate components: a main speaker unit and detachable sub speaker units. This segmentation allows the sub speakers to be independently attached or detached, enabling flexible communication modes (wired when attached, wireless when detached) and multiple audio output configurations, thereby resolving the contradiction between structural stability and adaptability.

Inventive Principle:

Principle #1Segmentation

AI summary

Disclosed are a main speaker, sub speaker and system including the same. The present invention includes a main speaker configured to receive a first audio signal from a first source device and output the received first audio signal and at least one sub speaker configured communicate with the main speaker by wire or wireless. Particularly, if the communication with the main speaker is connected, the sub speaker outputs the first audio signal. If the sub speaker is separated from the main speaker, the sub speaker outputs the second audio signal.
