Composite Headphone Merging Wired and Wireless Audio Systems

Solution Overview

Problem

Conventional headphones fail to meet user requirements for portability, high-quality sound effect, and low delay across various scenarios, as they are either non-portable, offer general sound quality, or are costly.

Innovation Solution

A composite headphone is designed by combining a wired headset with a wireless Bluetooth® headphone, allowing the wireless headphone to detach and operate independently for portability and high-quality sound, while connecting with the wired headset for low-delay wireless audio transmission, using a voice decoding chip to manage audio and voice processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a wired headset is used, then low delay and high sound quality are achieved, but portability is reduced

Engineering Contradiction:

Improvesound quality and delayVSAvoidportability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent combines a wired headset and a wireless Bluetooth headphone into a single composite headphone system. The wireless Bluetooth headphone can be detached and attached to the wired headset, merging the portability advantage of wireless headphones with the sound quality and low delay advantage of wired headsets into one unified device.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The composite headphone system provides multiple functions: it can operate as a standalone wireless Bluetooth headphone for portable use, or attach to the wired headset to function as a high-quality wired headphone. This multi-functionality allows the same device to adapt to different usage scenarios and requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If a wireless Bluetooth headphone is used, then portability is improved, but sound quality and delay performance deteriorate

Engineering Contradiction:

ImproveportabilityVSAvoidsound quality and delay

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent combines a wired headset and a wireless Bluetooth headphone into a single composite headphone system. The wireless Bluetooth headphone can be detached and attached to the wired headset, merging the portability advantage of wireless headphones with the sound quality and low delay advantage of wired headsets into one unified device.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The composite headphone system dynamically adapts its configuration based on usage needs. The wireless Bluetooth headphone can be detached for portable use or attached to the wired headset for high-quality audio, allowing the system to transition between different operational states to optimize performance for each scenario.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If separate wired headset and wireless headphone are purchased to meet all requirements, then all scenario needs are met, but cost increases

Engineering Contradiction:

Improvescenario coverageVSAvoidcost

AI summary

A composite headphone is provided. The composite headphone includes a wireless Bluetooth headphone and a wired headset. The wireless Bluetooth headphone is detachably arranged on the wired headset. When the wireless Bluetooth headphone separates from the wired headset, the wireless Bluetooth headphone operates independently and the wired headset operates independently. When the wireless Bluetooth headphone is arranged on the wired headset and a composite event is triggered, the wireless Bluetooth headphone cooperates with the wired headset, so that the wired headset operates as a wireless Bluetooth headphone. When the wireless Bluetooth headphone is arranged on the wired headset and no composite event is triggered, the wired headset charges the wireless Bluetooth headphone.
