PROBLEM TO BE SOLVED: To provide a sound generator of a vehicle, enabling minimizing of a void, and increase of a driving force or reduction in size, and preventing damage of a coil by suppressing play in a lateral direction (improved safety and reliability).SOLUTION: A sound generator of a vehicle includes a housing, a spring provided at a lower part of the housing, a drive part including an internal yoke and a magnet, being inserted in the housing to be stably fitted to the spring, for vertical sliding, a bobbin whose upper end is fixed to an upper part inside the housing, being extended downward in a manner to enclose the drive part, a coil wound along the periphery of the bobbin, and an external yoke fixed to the housing, being cylindrical and going around the outside of the coil and the internal yoke.

    【課題】空隙の最小化が可能で、駆動力の増大化又はサイズの縮小化が可能となり、そして、横方向への遊動抑制によってコイルの損傷防止(安全性及び信頼性向上)が可能となる車両のサウンドジェネレーターを提供する。【解決手段】本発明による車両のサウンドジェネレーターは、ハウジングとハウジング下部に設けられたスプリング、内部ヨークと磁石で構成され、ハウジングに挿入されスプリングに安着されて上下にスライディングする駆動部、ハウジング内側上部に上端が固定され駆動部を囲む形態で下方に延長されたボビンとボビンの周囲に沿って巻かれたコイル、及びコイルと内部ヨークの外側を回る円筒状でハウジングに固定された外部ヨークを含むことを特徴とする。【選択図】図1
