Abstract
The utility model discloses a kind of anthropomorphic hearing aids selection device, comprise mineral processing model and audition device, the bilateral symmetry of described mineral processing model is provided with the emulation duct that two are convenient to insert hearing aids, distance between described two emulation ducts is imitate the spacing between human body ears, described audition device is provided with the earphone jack that at least one can be connected with the hearing aids in described emulation duct, in described earphone jack, is inserted with apolegamy earphone.By making a mineral processing model, two the emulation ducts being used for inserting hearing aids being arranged on the both sides of mineral processing model, and distance being between the two set as imitate people's ear space, making the result of apolegamy more accurate.
Description
Technical field
The utility model relate to a kind of anthropomorphic 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, to add a height 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, the distance of two emulation holes is also different from the distance between normal human ear, 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.
In addition, auricle, the duct of ear all can produce certain impact to hearing aids, and thus, offer two circular cavities to test hearing aids simply by a flat board, its effect can be had a greatly reduced quality.
In addition, state-of-the art hearing aids must and the mating shapes of duct, like this, be just not suitable for apolegamy person and select, because his hearing aids of selecting probably does not mate with hole or the shape that emulates duct.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of anthropomorphic hearing aids selection device, by making a mineral processing model, two the emulation ducts being used for inserting hearing aids are 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 anthropomorphic hearing aids selection device, comprise mineral processing model and audition device, it is characterized in that: described mineral processing model is apery bust form structure, comprises head and chest, the both sides of described mineral processing model are provided with auricle, emulation duct is provided with in two ears, a hearing aids is respectively provided with in described emulation duct, described audition device is arranged in the inner chamber of described chest, described chest is provided with the earphone jack that at least one can be connected with the hearing aids in described emulation duct, in described earphone jack, is inserted with apolegamy earphone.
The anthropomorphic hearing aids selection device of aforesaid one, is characterized in that: the front of described mineral processing model arranges the display screen of a display sound spectrum.
The anthropomorphic hearing aids selection device of aforesaid one, it is characterized in that: described audition device comprises the acoustic coupler in the inner chamber being arranged on described chest, two of described mineral processing model between ear with acoustic coupler by two independently phonocatheter be connected, be also provided with microphone amplifying circuit between described acoustic coupler and earphone jack.
The anthropomorphic hearing aids selection device of aforesaid one, is characterized in that: described chest is provided with four earphone jacks.
The anthropomorphic hearing aids selection device of aforesaid one, is characterized in that: the bottom of described mineral processing model is also provided with tripod, for regulating the height of mineral processing model.
The beneficial effects of the utility model are:
1, adopt apery bust form structure, more there is compatibility; By the collection sound of auricle and the sound transmission of emulation duct, test effect is made more to tend to true;
2, emulate duct to carry out in advance, then prepare the hearing aids of multiple different model for apolegamy according to the shape of emulation duct, avoid the unmatched phenomenon of shape to occur;
3, by two the emulation ducts 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;
4, by the distance between two emulation ducts is set to the spacing of imitating people's ear, the apolegamy quality of hearing aids is improved further;
5, by arranging multiple earphone jack at audition device, the synchronous audition of many people is convenient to a hearing aids.
