In this case, it is preferable to detachably mount thespeaker portion 2 on the temple member. - Next, the
bone conduction speaker 8 adapted to be used in the present invention and shown inFigs. 4 to 8 will be described. Thebone conduction speaker 8 is constructed of: ayoke 21 provided with a centralmagnetic pole 22; a pair of diametrically-opposing dividedmagnets 24 disposed outside a doughnut-type voice coil 23 which surround the centralmagnetic pole 22; and, a vibrating board ordiaphragm 25 mounted on a pair of diametrically opposingupright support portions 26 of theyoke 21. - The
yoke 21 is slightly larger than thevoice coil 23, and provided with four extensions each radially outwardly extending in each of four directions. One pair of the four extensions form a pair of diametrically opposingmagnet support portions upright support portions diaphragm 25. Fixedly mounted on each of themagnet support portions magnet 24, which assumes a rectangular parallelepiped shape disposed adjacent to thevoice coil 23. Each of themagnet support portions 27 may assume a curved shape extending along thevoice coil 23. - Each of the diaphragm support

Thehousing 35 may be divided into an upper and a lower half. - In an assembling operation, the bone conduction speaker 37 is mounted in the
housing 35 through theplate yoke 33 in a floating manner. Consequently, vibration caused by a voice sound or by application of an audio input signal may be effectively transmitted to thehousing 35, which may realize the bone conduction speaker 37 excellent in efficiency. Furthermore, in construction of this embodiment, themagnets 24 are divided ones (in contrast with the conventional magnet assuming a circular shape an outer surface of which is surrounded by a casing), and coaxially disposed so as not to extend radially outwardly. This enables the bone conduction speaker 37 of this embodiment to be compact in size. - In use of the hearing aid of the present invention in making conversation to a conversation partner, it is necessary for the user to hand the partner the
main body portion 1 and have the partner talk to the microphone 3 of themain body portion 1. At the same time, it is necessary for the user to have thebone conduction speaker 8 brought into slight contact with the user's temple or its vicinities by using thegrip portion 9 and select a favorable contact area in which the user may most effectively pick up the transmitted voice sound through thebone conduction speaker 8. At this time, the user may control the transmitted voice sound in volume by turning thevolume control knob 5 of themain body portion 1. - In watching television, one of opposite end portions of the audio cable is electrically connected with the audio
cable connecting terminal 7 in a condition in which the other of the opposite end portions is electrically connected with an audio output terminal which is generally provided in a rear side of a television set. After that, as is in the case described above, the user wears thebone conduction speaker 8 on his head. More specifically, through theheadband 13, the head set, or the temple member of the eyeglasses, thebone conduction speaker 8 is brought into slight contact with the user's head. - The present invention has the construction described above. Consequently, the present invention is adapted to be used by a person suffering from some impairment in hearing ability when he or she makes conversation to others or watches television. The present invention is also adapted to be used by persons each normal in hearing ability when they make conversation to each other in a noisy environment.
