  • Fig. 8 is a plan view of the diaphragm of the bone conduction speaker adapted to be used in the present invention.
  • a hearing aid of the present invention is constructed of a main body portion 1 and a speaker portion 2, which is electrically connected with the main body portion 1.
  • the main body portion 1 is provided with a microphone 3, a power switch 4, a volume knob 5 and like components. Further, incorporated in the main body portion 1 are an amplifier and a driving battery for driving these components.
  • a speaker cable connecting terminal 6 is mounted on a side surface of the main body portion 1.
  • an audio cable connecting terminal 7 is further provided in the hearing aid (see Fig. 3).
  • the speaker portion 2 is constructed of: a bone conduction speaker 8; a grip portion 9 projecting outward from a side surface of the bone conduction speaker 8; and, a cable 10 for electrically connecting the speaker portion 2 with the main body portion 1 through a connector 11 which is inserted into the speaker cable connecting terminal 6.
  • the other end of the audio cable connected with the audio cable connecting terminal 7 is connected with an audio output terminal of an audio output unit.
  • the audio cable is inputting means for inputting an audio signal, which is issued from an audio output unit, to the main body portion 1.
  • Such an audio output unit comprises any output unit issuing a sound signal such as a voice sound signal, an audio signal and like signals from its audio output terminal, wherein the output unit may be any one of a television set, a CD player, a broadcasting radio receiver and like output units.
  • the user may hold the speaker portion 2 through its grip portion 9. It is also possible for the user to wear the speaker portion 2 through a headband, which enables the user to use both hands in a free manner.
  • a headband 13 is provided with an insertion opening 14 in which a shaft portion 9a of the grip portion 9 is mounted in an insertion manner (see Fig. 2).
  • the head set 17 is provided with a bone conduction speaker 8 in at least one of its ear engaging portions 16.
  • the ear engaging portions 16 are provided in opposite ends of a curved member 15 fitted to the back of the user's head (see Fig. 3).
  • mount the speaker portion 2 on a temple member of eyeglasses although the speaker portion 2 is mounted on an end portion of the temple member, it is also possible to mount the speaker portion 2 on an intermediate portion of the temple member). In this case, it is preferable to detachably mount the speaker portion 2 on the temple member.
  • the bone conduction speaker 8 is constructed of: a yoke 21 provided with a central magnetic pole 22; a pair of diametrically-opposing divided magnets 24 disposed outside a doughnut-type voice coil 23 which surround the central magnetic pole 22; and, a vibrating board or diaphragm 25 mounted on a pair of diametrically opposing upright support portions 26 of the yoke 21.
  • the yoke 21 is slightly larger than the voice 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 opposing magnet support portions 27, 27.
  • the remains of the extensions form a pair of diametrically opposing upright support portions 28, 28 for supporting the diaphragm 25.
  • Fixedly mounted on each of the magnet support portions 27, 27 is the magnet 24, which assumes a rectangular parallelepiped shape disposed adjacent to the voice coil 23.
  • Each of the magnet support portions 27 may assume a curved shape extending along the voice coil 23.
  • each of the diaphragm support portions 26, 26 assumes an upright shape, and is integrally formed with each of the upright support portions 28, 28 and provided with a blind hole 29 in its center.
  • the blind hole 29 is used to fixedly mount the diaphragm 25 on the yoke 21.
  • the diaphragm 25 has four extensions each radially outwardly extending in each of four directions.
  • an upper and a lower one of the extensions of the diaphragm 25 are provided with an upper and a lower through-hole 30, respectively.
  • Each of these through-holes 30, 30 corresponds in position to each of the blind holes 29.
  • the diaphragm 25 is provided with a central elongated opening 31 laterally extending in its central area. The diaphragm 25 is fixedly mounted on the diaphragm support portions 26, 26 through screws.
  • a plate yoke 33 Mounted on the diaphragm 25 is a plate yoke 33.
  • This plate yoke 33 extends along the central opening 31, has its thick wall portion positioned within the central opening 31 and has an upper surface of this thick wall portion be flash with an upper surface of the diaphragm 25.
  • the plate yoke 33 has its opposite thin wall portions fixedly mounted on a rear surface of the diaphragm 25 by suitable fastening means such as soldering and the like.
  • the plate yoke 33 has only its opposite thin wall portions fixedly mounted on the diaphragm 25 to permit its central thick wall portion to freely vibrate in a position corresponding to the central opening 31 of the diaphragm 25.
  • the central thick wall portion of the plate yoke 33 is provided with a pair of tapped holes 34 which is threadably engaged with a pair of screws 36 when the plate yoke 33 is incorporated in a housing 35.
  • the speaker 37 is entirely mounted in the housing 35.
  • the housing 35 may be divided into an upper and a lower half.
  • the bone conduction speaker 37 is mounted in the housing 35 through the plate 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 the housing 35, which may realize the bone conduction speaker 37 excellent in efficiency.
  • the magnets 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.
  • the hearing aid of the present invention 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 the main body portion 1. At the same time, it is necessary for the user to have the bone conduction speaker 8 brought into slight contact with the user's temple or its vicinities by using the grip portion 9 and select a favorable contact area in which the user may most effectively pick up the transmitted voice sound through the bone conduction speaker 8. At this time, the user may control the transmitted voice sound in volume by turning the volume control knob 5 of the main body portion 1.
  • 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.
  • the user wears the bone conduction speaker 8 on his head. More specifically, through the headband 13, the head set, or the temple member of the eyeglasses, the bone 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.
