Abstract
The utility model discloses an acoustical frequency induction input device of a mini-type coil hearing aid and is arranged nearby a hearing aid body. A mini-type coil is electrically connected with an input plug through a wire, because the utility model leads the mini-type coil to be mounted on the hearing aid body, the mini-type coil and an induction coil which is arranged in the hearing aid are constantly held in short distance, the field intensity of the hearing aid is even, the signals are stable, the input plug which is electrically connected with the mini-type coil through the wire can be directly and externally connected with output ports of power amplifier, radio, and walkman sound signal output devices and the like. The utility model can be quite conveniently utilized.
Description
Technical field
The utility model relates to a kind of hearing aids, particularly relates to a kind of hearing aids frequency induction input unit.
Background technology
At present, hearing aids mostly has an audio frequency input induction coil that is used for receiving the audio frequency field signal.The method that produces the audio-electromagnetically field signal is that the output of power amplifier is directly linked on the fixing big coil, and when hearing aids placed " T " shelves, the coil in the hearing aids can directly be sensed audio signal and amplify output by the back level.A kind of known seat cushion formula hearing aid receiving system (as shown in Figure 1), be to utilize the magnetoelectric induction principle, the magnetoelectric induction coil is embedded in seat cushion 1 ' and the backrest 2 ', link to each other with television set etc. with radio-cassette player with lead 3 ', when the deaf person is sitting on seat cushion 1 ' and the backrest 2 ', can increase magnetoelectric induction, increase the coverage that receives sound.But this big fixed coil is difficult for installing, and because the inhomogeneous jitter that causes of field intensity.In addition, the direct audio input port of each producer's hearing aids must could use by the different separately special audio interface of supporting former producer, costs an arm and a leg, and has only the professional just to understand use.
Summary of the invention
The purpose of this utility model be to provide a kind of easy to use, signal strength signal intensity is reliable and stable, need not the hearing aids frequency induction input unit of special purpose interface,
For achieving the above object, solution of the present utility model is:
A kind of hearing aids frequency induction input unit is provided with a miniature coils near the hearing aids body.
Described miniature coils is fixed on the hearing aids body by a fixed mechanism.
Described fixed mechanism is a silicon rubber loop.
Described miniature coils is electrically connected an input plug by lead.
Because the utility model is that miniature coils is fixed on the hearing aids body with fixed mechanism, make the induction coil in miniature coils and the hearing aids keep closely constant, the field intensity of hearing aids is even, signal stabilization, and the output port of sound signal outputting devices such as the input plug that miniature coils is electrically connected by lead can direct external power amplifier, broadcast receiver, walkman, very convenient to use.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is known seat cushion formula hearing aid receiving system figure;
Fig. 2 is a structural representation of the present utility model.
Embodiment
As shown in Figure 2, the utility model hearing aids frequency induction input unit is provided with a miniature coils 2 near hearing aids body 1, and this miniature coils 2 is fixed on the hearing aids body 1 by a fixed mechanism 3.Described fixed mechanism 3 can adopt silicon rubber loop.
Described miniature coils 2 is electrically connected the input plug 5 of signal input by lead 4, the output port of sound signal outputting devices such as this input plug 5 can direct external power amplifier, broadcast receiver, walkman.
Claims (5)
1, a kind of hearing aids frequency induction input unit is characterized in that: be provided with a miniature coils near the hearing aids body.
2, hearing aids according to claim 1 frequency induction input unit, it is characterized in that: described miniature coils is fixed on the hearing aids body by a fixed mechanism
