Chordophone with Integrated Speaker and Wireless Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chordophones lack integrated speaker and accompaniment functions, making it difficult for violin practitioners to practice and perform with simultaneous sound output and accompaniment.
Innovation Solution
A chordophone with a speaker unit integrated into its body, featuring a cut-out plate with a grille, a bracket for the speaker, a control unit, and a communication module, allowing for wireless sound output and control via a user terminal, enabling lesson mode practice and accompaniment functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a speaker unit is integrated into the chordophone body, then sound output and accompaniment functions are enabled, but the structural complexity increases
Solution Approach 1:
The speaker unit is integrated into the chordophone body by combining the speaker, bracket, cut-out plate with grille, and control unit into a unified assembly that becomes part of the instrument's structure, enabling sound output functionality without requiring separate external devices
Solution Approach 2:
The chordophone body is designed to serve multiple functions: traditional string sound production plus amplified sound output through the speaker unit, allowing the instrument to function both as a acoustic instrument and an amplified performance/practice tool
2Reliability
If a grille is formed on the cut-out plate corresponding to the speaker diameter, then sound output efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The grille is specifically positioned and sized to match the speaker's sound output characteristics, creating an optimized local structure that directs and enhances sound projection from the speaker while maintaining overall body integrity
3Ease of operation
If a control unit and communication module are added for wireless control, then ease of operation is improved, but device complexity increases
Solution Approach 1:
Physical control mechanisms are replaced with wireless electronic control through the communication module, allowing the user to control speaker functions remotely via a user terminal without requiring physical buttons or switches on the instrument itself

AI summary
The present invention provides a chordophone including a body configured to have a top plate, a bottom plate, and a side plate connected to the top plate and the bottom plate, which comprises: a cut-out plate formed by cutting the bottom plate, and configured to have a grille formed on a portion penetrated of the cut-out plate; a bracket formed in a shape corresponding to the cut-out plate and configured to have a base plate coupled to an inner side of the cut-out plate; and a speaker unit configured to have a speaker installed in the bracket, a control unit for controlling an output of the speaker, and a communication module for allowing a sound source output from the speaker to be received from an external user terminal, in which the grille is formed in a size and shape corresponding to a diameter of a side on which a sound of the speaker is output, and a through-hole is formed penetrated on the base plate at a corresponding position to the grille and with a corresponding shape to a shape of the sound output side of the speaker.
