To provide an on-vehicle speaker system and audio system with improved output characteristics of a low sound region of rear speakers.SOLUTION: When an audio signal is applied to a voice coil 205 from an audio device 1, a voice coil bobbin 204 is vibrated together with a connected diaphragm 208 in response to amplitude of an audio signal by an electromagnetic actuation between a magnetic flux to be generated from a magnetic circuit 220 and an audio signal flowing through the voice coil 205, so as to generate sound corresponding to an audio signal. A front speaker 2(a1) and a rear speaker 3(b1) have nearly the same constitutions. The number of turns and a winding width ChR of the voice coil 205 of a rear speaker 3(b2) are twice the number of turns and a winding width Chf of the voice coil 205 of a front speaker 2(a2).SELECTED DRAWING: Figure 3

    【課題】リアスピーカの低音域の出力特性を向上した「車載用スピーカシステム及びオーディオシステム」を提供する。【解決手段】オーディオ装置1からオーディオ信号がボイスコイル205に印加されると、磁気回路220から発生する磁束と、ボイスコイル205を流れるオーディオ信号との電磁作用によって、オーディオ信号の振幅に応じて、ボイスコイルボビン204が連結されている振動板208と共に振動し、オーディオ信号に応じた音が発生する。フロントスピーカ2(a1)と、リアスピーカ3(b1)とは、ほぼ同様の構成を備えているが、リアスピーカ3(b2)のボイスコイル205の巻数と巻幅ChRは、フロントスピーカ2(a2)のボイスコイル205の巻数と巻幅Chfの2倍とする。【選択図】図3
