PROBLEM TO BE SOLVED: To provide a hearing aid that allows a user to easily hear sound without the need for using a power supply such as a battery and to freely move around. SOLUTION: It is important to make sound collection effective by providing an angle and a curved face to collect a sound received in a reflection plate 1 at an ear hole and keeping a part behind the ear to be a face easily facing the sound. Thus, the part of the ear and the reflecting plate are all faced to sound thereby enhancing the effect of sound collection by the both. The reflecting plate has a semispherical curved face at upper and lower parts to pick up sound and sound in the lateral direction is collected to the ear hole by keeping an angle of 45-degrees with respect to the ear. The angle made to the reflection plate is also required to push forward the part behind the ear. A frame 3 is hooked behind the ear, the part behind the ear is instantaneously pushed forward by the reflection plate to form sound collection. The reflection plate is fitted to both end of a spring form frame and fixed to clip a face inbetween. Thus, the form of sound collection can be completed. COPYRIGHT: (C)2003,JPO
