An accessory detachably mounted on a mobile phone for a hearing aid is provided to listen an easily amplified sound by a blind person wearing the hearing aid. In an accessory(200) detachably mounted on a mobile phone for a hearing aid, a frame(210) is electrically connected to a voice coil by being inserted into a connection unit. A yoke(220) forms a magnetic circuit where a magnetic flux applied from an outside passes. A magnet(230) is formed inside the yoke(220) to generate the magnetic flux in a predetermined direction. A plate(240) is attached to a top surface of the magnet(230) to form the magnetic circuit where the magnetic flux generated from the magnet(230) passes. A protection plate(250) covers an open end by being assembled on a top surface of the frame(210). And, a hearing aid coil(260) is electrically connected to a connection terminal of the frame(210) to vibrate a vibration plate of the hearing aid worn by a deaf person. |
