VOICE INPUT DEVICE

To provide a technique capable of improving soundproofness of a voice input device.SOLUTION: A sound input device having a function of suppressing leakage of voice uttered by a user to the outside includes: a casing for forming a first space between a user's mouth and itself by opening one surface side and pressing the one surface side while covering the user's mouth; a microphone for detecting voice; and a sound absorption member for absorbing voice. A second space in which the sound absorption member is disposed is formed within the casing, a first through hole for connecting the first space and the second space, and a second through hole for connecting the second space and the outside of the casing are formed in the casing, and the sound absorption member is disposed between the first through hole and the second through hole in a route for propagating voice with the second space as a medium, and is disposed along the longitudinal direction of the casing.SELECTED DRAWING: Figure 2 【課題】音声入力装置の防音性を向上できる技術を提供する。【解決手段】使用者が発する音声の外部への漏えいを抑制する機能を有する音声入力装置は、一面側が開口し一面側が使用者の口を覆って押し当てられることによって口との間に第１の空間を形成する筐体と、音声を検出するマイクロフォンと、音声を吸収する吸音部材とを備え、筐体の内部には吸音部材が配置された第２の空間が形成されており、筐体には、第１の空間と第２の空間とを連通する第１の貫通孔と、第２の空間と筐体の外部とを連通する第２の貫通孔とが形成されており、吸音部材は、第２の空間を媒質とする音声が伝搬する経路において、第１の貫通孔と第２の貫通孔との間に配置されており、筐体の長手方向に沿って配置されている、ことを特徴とする。【選択図】図２
