PROBLEM TO BE SOLVED: To implement a hearing aid which is connected to a connector in accordance with the number of persons having conversations to enable persons to have conversations with a person whose hearing is failing, without loud voice.SOLUTION: A funnel-shaped hearing aid 2 suitable for collecting sounds is connected to one of both ends of a tube 3, and the other is connected to a connector port 1. In the same manner, another hearing air and another tube are connected to the connector port 1. When two persons use the hearing aids to have conversations, one person whose hearing is failing puts a hearing aid 2a on his or her ear, and the other whose hearing is not failing puts another hearing aid 2b connected to the connector port 1, near his or her mouth. When another person participates in the conversations, he or she puts a hearing aid 2c near his or her mouth. The number of connector ports is increased to allow more persons to have conversations. When the number of persons having conversations is less than 4, unused connector ports 1 are covered with lids 4.COPYRIGHT: (C)2013,JPO&INPIT【課題】会話人数によって、聴話器をコネクターに接続することにより聴力の衰えている人に、大きな声をせずに会話ができ聴話器を実現する。【解決手段】管3の両端の一方に音を捕集しやすいロート状の聴話器2を接続し、もう一方をコネクター1に接続する。これと同じように別の聴話器と管をコネクター1に接続する。使用とするとき聴力の悪い人は、聴話器2aを耳にし、聞こえの悪くない人は、他方のコネクター1に接続されている聴話器2bを口部に接して会話する、3人で会話をする時は、聴話器2cを口部に接続し手会話する、コネクターを増やせば多人数が会話ができるものである、使用しないコネクター1は4人以上で会話をしない時はふた4をする。【選択図】図1
