Zusammenfassung:	To enable a noise counterplan of a speaker with a simple configuration.SOLUTION: A speaker 10 includes: a bobbin 15 with voice coils 31 arranged therein; a diaphragm 13 connected to the bobbin 15; a frame 11 for supporting the diaphragm 13; and a magnetic circuit part 17 including a magnet 22. The speaker includes: first conductive bodies 41 connected to the voice coils 31 and to be drawn out of the bobbin 15A; and second conductive bodies 51 connected to the first conductive bodies 41 and to penetrate the magnet 22.SELECTED DRAWING: Figure 2 【課題】簡易な構成でスピーカのノイズ対策を可能にする。【解決手段】ボイスコイル３１が設けられたボビン１５と、ボビン１５に接続される振動板１３と、振動板１３を支持するフレーム１１と、マグネット２２を含む磁気回路部１７とを備えるスピーカ１０において、ボイスコイル３１に接続され、ボビン１５Ａの外に引き出される第１導電体４１と、第１導電体４１に接続され、マグネット２２を貫通する第２導電体５１とを備えている。【選択図】図２
