  Next, a second modification of the hearing aid device A will be described with reference to FIGS.

[Second Modification of Hearing Aid Device A]
14 to 16 show a second modification example of the hearing aid device A, and the hearing aid device A according to the second modification example has the same basic structure as the hearing aid device A as the first modification example described above. However, the loop antenna 70 is different in that it can be arranged in the vicinity of the induction coil 85 incorporated in the hearing aid 69.

  That is, as shown in FIG. 14, the loop antenna 70 is attached to an antenna body 71 formed in a loop shape, a connection cord 72 having a base end connected to the antenna body 71, and a distal end portion of the connection cord 72. The plug 73 can be connected to the external output terminal 18 of the receiver 10 so as to be freely inserted and removed.

  As shown in FIG. 14, the antenna body 71 is built in a sheet-like adhesive body 78, and one surface 86 a of a hook-and-loop fastener 86 is stretched on one surface of the adhesive body 78.

  14 and FIG. 15 or the pocket-accommodating hearing aid 69 shown in FIGS. 14 and 16 incorporates the induction coil 85 described above and is close to the induction coil 85. The other piece 86b of the hook-and-loop fastener 86 is stretched on the side wall 69a of the hearing aid 69.

  Moreover, one piece 86a of the hook-and-loop fastener 86 is detachably bonded to the other piece 86b of the hook-and-loop fastener 86, and in this bonded state, an antenna is connected to the induction coil 85 built in the hearing aid 69 as shown in FIG. The main body 71 is arranged close to the opposing state so that the magnetic coupling between the induction coil 85 and the antenna main body 71 is ensured satisfactorily.

  Here, as shown in FIG. 18, when the attitude (angle) of the induction coil 85 built in the hearing aid 69 changes from (a) to (d) with respect to the fixed magnetic induction loop antenna 87. Changes in the effect of magnetic coupling occur. Reference numeral 88 denotes a magnetic loop amplifier, and G denotes a magnetic field line.

  That is, the induction coil 85 has the maximum magnetic coupling effect with the magnetic induction loop antenna 87 in the posture (a), but the magnetic coupling effect is attenuated in the postures (b) to (d).

  In this regard, in the present embodiment, the other piece 86b of the hook-and-loop fastener 86 in which the sheet-like adhesive body 78 incorporating the antenna main body 71 is stretched on the side wall 69a of the hearing aid 69 via the piece 86a of the hook-and-loop fastener 86. Since the antenna body 71 can be secured in the posture (a) with respect to the induction coil 85 simply by bonding to the magnetic coil, the magnetic coupling can be maintained in the optimum state.

  At this time, the hook-and-loop fastener 86 can prevent electrical contact failure caused by sweat or vibration during use.

  Further, when the loop antenna 70 is unnecessary, it is only necessary to peel the adhesive 78 from the surface of the hearing aid 69 via the surface fastener 86, and the loop antenna 70 can be easily removed.

  Here, when the base end portion of the connection cord 72 is detachably connected to the adhesive body 78 and the loop antenna 70 is unnecessary, the adhesive body 78 is left attached to the hearing aid 69 and the adhesive body is used. It is also possible to remove the connection cord 72 from 78.

  Thus, once the adhesive body 78 is attached to the hearing aid 69, the loop antenna 70 can be used by simply connecting the connection cord 72 to the adhesive body 78 as necessary. In addition, it is also possible to prevent the connection cord 72 and the plug 73 from being hindered in a non-use state by simply cutting the connection cord 72 from the adhesive body 78.

  Even if the adhesive 78 is left attached to the hearing aid 69, the adhesive 78 is very lightweight, so that the hearing-impaired person M3 wearing the hearing aid 69 does not feel uncomfortable.

  Further, in the present embodiment, as shown in FIG. 14, the plug 73 of the loop antenna 70 can be detachably connected to the external output terminal 18 of the mobile phone as the receiver 10.

  The means for adhering the adhesive body 78 to the side wall 69a of the hearing aid 69 is not limited to the hook-and-loop fastener 86, and it is possible to prevent poor electrical contact caused by sweat or vibration during use. What is necessary is just to be able to bond easily and reliably.

  Thus, in the present embodiment, the antenna body 71 of the loop antenna 70 can be adhered to the side wall 69a of the hearing aid 69 close to the induction coil 85. The optimum distance and angle can be maintained in the optimum state as close as possible.

  As a result, the loss of magnetic coupling between the antenna body 71 and the induction coil 85 can be reduced as much as possible, and even when the output signal is a small output, the hearing aid 69 can reliably receive and save Power consumption (reduction of battery consumption) can be achieved, and a signal with appropriate sound volume can be efficiently transmitted with good sound quality, which can have a great effect particularly for a hard-of-hearing person. .

  Further, since the output signal transmitted from the antenna body 71 arranged in the vicinity of the induction coil 85 of the hearing aid 69 can be made as small as possible, it is possible to prevent an unnecessary leakage magnetic field from being generated, Even if a hearing-impaired person receiving signals with different reception frequencies is nearby, it is possible to listen to information reliably and safely without mutual interference.

  Moreover, the transmission / reception channels can be used simultaneously according to the number of channels of the transmitter and the receiver. For example, in the case of the C band of 300 MHz band, the desired number of channels can be determined from the number of 13 channels. Can be selected and all channels can be used simultaneously.

  Therefore, even when a plurality of hearing-impaired persons M3 are close to each other, a wide variety of different information can be transmitted simultaneously and reliably.

  In addition, since the loop antenna 70 can be miniaturized as much as possible, it is possible to satisfactorily ensure the usability when it is worn or carried with a hearing aid.
