Wearable Haptic Device for Multi-Device Audio Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable music listening solutions, such as headphones and earbuds, fail to provide the tactile experience of sound similar to live music events and are limited by single-channel wireless communication, excluding hearing-impaired users and preventing multi-device connectivity.
Innovation Solution
A wearable haptic device with attached transducers and a power source, connected to a music playing device, that produces vibrations based on audio signals and enables wireless communication with multiple output devices, simulating the experience of live music and allowing multi-device connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If headphones or earbuds are used for portable music listening, then audio output is provided, but tactile feedback similar to live music experience is not achieved
Solution Approach 1:
The audio signal is segmented into different frequency components, with bass frequencies directed to the vibration motor for tactile feedback and other frequencies directed to headphones for auditory output. This segmentation allows the system to provide both tactile and auditory experience simultaneously, resolving the contradiction between tactile feedback quality and listening experience.
Solution Approach 2:
The patent combines multiple output devices (headphones and vibration motor) into a single wearable system that processes audio signals through different pathways. By merging auditory and tactile output channels, the system achieves both reliable tactile feedback and high-quality listening experience that mimics live music.
2Adaptability or versatility
If wireless headphones with single communication channel are used, then wireless connectivity is provided, but multi-device communication capability is limited
Solution Approach 1:
The wearable device is designed with universal communication capability that can function as either a traditional single-channel wireless headphone or as a multi-device communication hub. The system can simultaneously maintain connections with multiple devices (smartphone, tablet, computer) and route audio signals from any connected device through the same vibration motor and headphone output, providing adaptability without increasing device complexity.
