To provide a sub-woofer capable of reducing a sound caused by bumper vibration.SOLUTION: A sub-woofer 100 comprises: a sound output unit 110 that is provided to an interior panel 10 of a vehicle 8 and that outputs a sound; a housing 120 that is provided to a gap between the interior panel 10 and a frame of the vehicle 8 so as to extend from the sound output unit 110 toward a through-hole 14b formed in the frame; and a guide 130 that is provided between a bumper provided outside the frame so as to cover the through-hole 14b and the housing 120 and that guides a sound output from the housing 120 in a direction different from an advancing direction of the sound propagated through the internal space of the housing 120. The guide 130 is disposed such that an extension line L which is a tangent line of a wall surface of a member forming the guide 130 inclines with respect to a normal N perpendicular to an inner surface of the bumper.SELECTED DRAWING: Figure 8

    【課題】バンパーの振動に起因して生じる音を低減できるサブウーファを得ること。【解決手段】サブウーファ100は、車両8の内装パネル10に設けられ音を出力する音出力部110と、内装パネル10と車両8のフレームとの間の隙間に設けられ、音出力部110からフレームに形成される貫通孔14bに向かって伸びるハウジング120と、貫通孔14bを覆うようにフレームの外側に設けられるバンパーとハウジング120との間に設けられ、ハウジング120から排出される音を、ハウジング120の内部空間を伝搬する音の進行方向とは異なる方向に向かうように案内するガイド部130とを備える。そして、ガイド部130は、ガイド部130を形作る部材の壁面の接線である延長線Lが、バンパーの内側面に垂直な法線Nに対して斜めになるように配置される。【選択図】図8
