Abstract
The utility model discloses a kind of hearing aids selection device, comprise mineral processing model and base machine box, the bilateral symmetry of described mineral processing model is provided with the hole that two are convenient to insert hearing aids, distance between described two circular cavities is imitate the spacing between human body ears, described base machine box is provided with the earphone jack that at least one can be connected with the hearing aids in described hole, in described earphone jack, is inserted with monitoring earphone.By making a mineral processing model, the two circular cavities being used for inserting hearing aids is arranged on the both sides of mineral processing model, and distance is between the two set as imitate people's ear space, make the result of apolegamy more accurate.
Description
Technical field
The utility model relate to a kind of hearing aids selection device, belongs to hearing aids selection technical field.
Background technology
People, after perception oneself impaired hearing declines, must seek medical advice medical, then according to the suggestion hearing aids of doctor, improve to greatest extent, recover hearing in damaged condition.
Because everyone auricle, duct, cavity of concha are different, in order to coincide with duct the best, to play the optimum efficiency of hearing aids, simultaneously also comfortable in order to wear, preparation hearing aids must configure end user's spot sampling mold.
But hearing aids is also a kind of commodity, manufacturer is different, kind is different, function number difference, the good and bad difference of performance, price height are different, also exist preparation front in numerous product selection and comparison go out the link that a most suitable user wears.
But the every a product in numerous hearing aid product is all on-the-spot is very unpractical for examination hearer customizes ear mold audition, therefore apolegamy is carried out to hearing aids and to seem outbalance.
Existing hearing aids selection device normally offers two for inserting the hole of hearing aids on one piece of panel, testing teacher of the joining inserts in hole by needing the hearing aids of audition, the earphone that hearing aids and this apolegamy equipment are connected is connected, and apolegamy person carries out audition by wearing this earphone.
But two of this matching device are arranged in the same way for the hole inserting hearing aids, distance between two circular cavities and the distance between normal human ear are also different, and normal human ear is long in the both sides of head, and ear hole towards being relative, these all can have influence on the accuracy of apolegamy.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of hearing aids selection device, by making a mineral processing model, the two circular cavities being used for inserting hearing aids is arranged on the both sides of mineral processing model, and distance is between the two set as imitate people's ear space, make the result of apolegamy more accurate.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of hearing aids selection device, comprise mineral processing model and base machine box, the bilateral symmetry of described mineral processing model is provided with the hole that two are convenient to insert hearing aids, distance between described two circular cavities is imitate the spacing between human body ears, described base machine box is provided with the earphone jack that at least one can be connected with the hearing aids in described hole, in described earphone jack, is inserted with monitoring earphone.
Aforesaid a kind of hearing aids selection device, is characterized in that: the spacing between described two holes is between 8cm-22cm.
Aforesaid a kind of hearing aids selection device, it is characterized in that: in described base machine box, be provided with acoustic coupler, described two circular cavities with between acoustic coupler by two independently phonocatheter be connected, be also provided with microphone amplifying circuit between described acoustic coupler and earphone jack.
Aforesaid a kind of hearing aids selection device, is characterized in that: described base machine box is provided with four earphone jacks.
Aforesaid a kind of hearing aids selection device, is characterized in that: described mineral processing model is apery head model structure.
Aforesaid a kind of hearing aids selection device, is characterized in that: the bottom of described base machine box is also provided with tripod.
Aforesaid a kind of hearing aids selection device, is characterized in that: described base machine box is also provided with the volume knob consistent with described earphone jack quantity.
Aforesaid a kind of hearing aids selection device, is characterized in that: described base machine box is also provided with USB interface.
The beneficial effects of the utility model are:
1, by the two circular cavities being used for inserting hearing aids being arranged on the both sides of mineral processing model, imitating people's ear and listening to sound from the both sides of head, making apolegamy effect true and accurate more;
2, by the distance between two circular cavities being set to the spacing of imitating people's ear, the apolegamy quality of hearing aids is improved further;
3, by arranging multiple earphone jack at base machine box, the synchronous audition of many people is convenient to a hearing aids.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of hearing aids selection device of the utility model;
Fig. 2 is the sound conduction schematic diagram of a kind of hearing aids selection device of the utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
