Solution Overview
Problem
Existing sounding devices with bone conduction speakers face challenges in completely preventing sound leakage even when in contact with a human body, and are limited in their application beyond audio listening.
Innovation Solution
A pet toy equipped with both a bone conduction speaker and a normal speaker, where the output control unit manages sound output from both speakers to minimize sound leakage and enhance usability, by adjusting volume and content based on contact detection and orientation, allowing for animal sounds and human-like language to be emitted simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bone conduction speaker is used to output sound, then sound can be transmitted through bone conduction when in contact with a human body, but sound leakage cannot be completely prevented
Solution Approach 1:
The sounding device is divided into two independent speaker systems: a bone conduction speaker for bone conduction transmission and a normal speaker for air conduction transmission. Each speaker handles different functions, allowing the bone conduction speaker to focus on reliable bone conduction transmission while the normal speaker manages sound leakage control through active noise cancellation or masking sounds.
Solution Approach 2:
The system dynamically adjusts the output parameters of both speakers based on contact detection. When contact with a human body is detected, the bone conduction speaker activates for reliable transmission, while the normal speaker simultaneously outputs counter-sounds or adjusts volume to prevent sound leakage. The output control unit coordinates both speakers to optimize transmission reliability while minimizing harmful sound leakage.
2Adaptability or versatility
If a bone conduction speaker is used for audio listening, then bone conduction audio transmission is achieved, but the device cannot be used for other purposes
Solution Approach 1:
The sounding device incorporates both a bone conduction speaker and a normal speaker, enabling it to perform multiple functions: bone conduction audio transmission, normal audio playback, and pet sound output. The output control unit intelligently switches between different modes and functions based on usage scenarios, making the device versatile for both human audio listening and pet communication applications.
Solution Approach 2:
The system dynamically switches between different operating modes: bone conduction mode for human audio listening, normal speaker mode for general audio playback, and pet sound mode for animal communication. The output control unit adjusts the activation state of each speaker based on detected contact and selected function, allowing the device to adapt to various applications while maintaining reliable bone conduction transmission when needed.
3Adaptability or versatility
If both a normal speaker and a bone conduction speaker are used, then sound leakage can be reduced and application range expanded, but device complexity increases
Solution Approach 1:
The device merges a normal speaker and a bone conduction speaker into a single integrated sounding unit with unified control. The output control unit coordinates both speakers to work together for sound leakage reduction and can independently activate either speaker based on the application. This merged design achieves multi-functionality and sound leakage control while managing complexity through integrated control architecture.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces sound leakage from the bone conduction speaker by using the normal speaker to drown out its output, making it easier to hear sounds from the bone conduction speaker when in contact with a human body, thereby enhancing user experience and expanding the device's application range.
