To provide a train approach warning device provided with a bone conduction speaker which has a secured safety and mitigates an influence of battery exhaustion when a cable less coupling between a body part and a headset part is adopted.SOLUTION: A wireless communication is held between a transmission and reception part 66 of a body part 60 and a transmission and reception part 71 of a headset part 70. When a signal reception part 33 of the body part 60 receives a train approach signal, a bone conduction speaker 41 of the head set 70 is made to discharge train approach warning sound, when the reception part receives a normal state confirmation signal, a normal state confirmation sound is discharged from the bone conduction speaker 41 and when any of these signals are not received, the bone conduction speaker 41 is made to discharge an abnormality notification sound and a light emitting part 74 of the headset part 70 is made to flash. When a battery of the body part 60 is exhausted, the light emitting part 74 is also made to flash.SELECTED DRAWING: Figure 1
【課題】骨伝導スピーカを具備した列車接近警報装置について本体部とヘッドセット部との間をケーブルレス化するに際して安全性を確保し更に電池切れの影響を緩和する。【解決手段】本体部60の送受信部66とヘッドセット部70の送受信部71とに無線通信を行わせて、本体部60の信号受信部33が列車接近信号を受信したときには列車接近警報音をヘッドセット部70の骨伝導スピーカ41から発出させ、正常状態確認信号の受信時には正常状態確認音を骨伝導スピーカ41から発出させ、それらの信号を何れも受信しないときには異常通知音を骨伝導スピーカ41から発出させるとともにヘッドセット部70の発光部74を点滅させる。本体部60の電池切れでも発光部74を点滅させる。【選択図】 図1
