Hearing aid

Abstract

Abstract PURPOSE:To obtain the voice of a stable voice level without being influenced by the behavior of a user by generating a voice magnetic field by means of an induction coil composed of small-sized coils. CONSTITUTION:The induction coil 13A of a voice magnetic field generating part 13 is composed by using the small-sized coils. Consequently, when the voice magnetic field generating part 13 is mounted to the upper half part of the body of a user 21, for an ear fitting type hearing aid 12, even though the user 21 executes a behavior (namely, the behavior to incline a head in a right and left direction or in a front and rear direction, or to rotate the head in a horizontal direction), a large fluctuation is not generated to a pickup signal IDT obtained from an induction coil 12A to be magnetically connected to a voice magnetic field HO. Thus, the voice of the practically almost optimum voce level can be always obtained from an earphone 12C without being influenced by the behavior of the user 21.
