PROBLEM TO BE SOLVED: To provide an on-vehicle microphone device which can secure safety property without deviation of a sight line of a driver and in which microphone characteristics are not deteriorated.SOLUTION: There is provided an on-vehicle microphone device in which a microphone 1 is attached to a microphone cover 10, in which a sound transmission layer 12 is provided on an interior surface 11a of a microphone cover housing 11 for concealment of an open hole 13 on the microphone cover housing 11. In addition, arrangement is performed so that the open hole 13 surrounds a microphone sound hole 7 of the microphone 1. When the microphone 1 is attached to the microphone cover 10, a protrusion 5S for preventing sound leakage is arranged so as to surround the open hole 13 of the microphone cover 10, and by elastic deformation of the protrusion 5S for preventing sound leakage, the space between the microphone 1 and the microphone cover 10 is sealed.SELECTED DRAWING: Figure 1

    【課題】運転者の視線を逸らすことなく、安全を確保でき、且つマイクロホン特性が劣化しない車載マイクロホン装置を提供する。【解決手段】マイクロホン1をマイクロホンカバー10に装着した車載マイクロホン装置であって、マイクロホンカバー筐体11の内装面11aに通音層12を設け、マイクロホンカバー筐体11の貫通孔13を隠蔽する。また、貫通孔13が、マイクロホン1のマイクロホン音孔7を取り囲むように配置する。マイクロホン1をマイクロホンカバー10に装着したとき、音漏れ防止用突起5Sが、更にマイクロホンカバー10の貫通孔13を取り囲むように配置され、音漏れ防止用突起5Sが弾性変形することで、マイクロホン1とマイクロホンカバー10との間を密閉する。【選択図】 図1
