Fig. 9 is when using jointly with four kinds of dissimilar sound boots, comprises the acceptor device 10 of angled antenna 20 and comprises the schematic diagram of the acceptor device 110 of non-angled antenna 120.Figure 9 illustrates direction 94 direction separately of antenna 20,120 relative user's noses 96, wherein direction 94 is passed nose from prolonging between the ears.
In Fig. 9, be labeled as in the structure of " B ", acceptor device 10 uses with dissimilar hearing instruments/sound boots, make when acceptor device is connected to boots and hearing instrument and wears on user's ear 98, acceptor device 10 is compared with structure A and has been rotated 90 ° by counter clockwise direction, thereby makes the Center Symmetry Plane 90 of output interface device parallel with the direction 94 of user's nose 96.In this case, the second portion 60 of antenna 20 has the best re-pointing with respect to the direction 94 of user's nose 96, and first 58 has least desirable sensing now.In a word, but, thereby the performance of antenna is identical with structure A.
In the structure that is labeled as " C ", the type of hearing instrument/sound boots is as follows, and acceptor device 10 is compared with structure B and rotated 90 ° by counter clockwise direction, thereby makes Center Symmetry Plane 90 have the sensing identical with structure A now.Because 90 ° curved shape of antenna 20, antenna 20 has the performance identical with B with structure A.
In be labeled as in the structure of " D ", the type of hearing instrument/sound boots is as follows, acceptor device 10 is compared with structure C by counterclockwise having rotated 90 °, thereby make Center Symmetry Plane 90 have now identical with structure B towards.Because 90 ° curved shape of antenna 20, antenna 20 has the performance identical with C with structure A, B.
Therefore, by using angled antenna 90, the performance of antenna 20 and acceptor device 10 are irrelevant in fact with the hearing instrument/sound boots of its particular type of together using.
As follows with the alternative embodiment that the sound boots have nothing to do in order to obtain this antenna performance, use antenna 120, this antenna or plane, thereby definition antenna plane 92, or has an axial symmetry, thereby definition antenna direction 92, wherein the sensing of antenna plane 92 or antenna direction 92 is respectively with respect to the angle between 90 one-tenth 30 ° to 60 ° of the Center Symmetry Plane of output interface device, preferably between 40 ° to 50 °.If antenna 120 is planes, its magnetic loop antenna preferably then, and if it has axial symmetry, then be preferably ferrite antenna or air core coil antenna.Optimal, as shown in Figure 9, the angle between the symmetrical plane 90 of antenna direction 92 and output interface device is about 45 °.In this case, in structure A, namely since pin 76A to the direction 94 of the feasible Center Symmetry Plane 90 vertical user's noses 96 by its definition of the sensing of 76C, angle between antenna direction 92 and the Center Symmetry Plane 94 is 45 °, thereby compare the sensing situation of the direction 94 of antenna plane 92 or antenna direction 92 vertical user's noses 96, will produce the medium performance of antenna 120.
In structure B, wherein because of the difference of sound boots type, the sensing of the Center Symmetry Plane 90 of output interface device has changed 90 ° with respect to the direction 94 of user's nose 96, and similarly antenna direction 92 also has been rotated counterclockwise 90 °.Yet because angle at 45 between the Center Symmetry Plane 90 of antenna direction 92 and output interface device, the direction 94 of user's nose 96 still is 45 ° with the angle of antenna direction.So antenna still keeps the performance identical with structure A.
