Description
Technical field
The utility model relates to hearing aids, relates in particular to the improvement of general-purpose type duct hearing aids, in the IPC International Patent Classification (IPC), belongs to H04R25/02 group.
Background technology
Hearing aids (hearing aid) helps hearing disabilities person to improve dysacousis, and then the unit of raising and his conference communicative competence and instrument etc.Hearing aids mainly contains these 4 types: boxlike hearing aids, eyeglass hearing aids, ear-level hearing aid and customized type hearing aids.
In 4 kinds of top hearing aidss, the customized type hearing aids can go customized according to the shape of our everyone ear, is fit to individual's ear.Like this, wear more comfortablely, get easily and wear; Can make full use of the sound collecting function of external ear; More inconspicuous; Mode receives calls normally.Therefore, the customization machine receives liking of users with small and exquisite, hidden characteristic always deeply.But the making of customization machine need be tested teacher of the joining scene and got ear appearance, send factory's customization casing, often needs the 2-3 time-of-week, and the user just can take loom.Also just based on the considering of convenience, many companies make improvement based on the customization machine one after another, reach thousand times die trial on the experience structural engineer, and grind the human antrum auris structure deeply, produce to meet the standard duct machine that most of people's ducts use, i.e. general-purpose type duct hearing aids.
Though yet general-purpose type duct hearing aids is to meet most of people's ducts to use; The goodness of fit that can't look like customized type hearing aids and duct is so high; In order to prevent to wear the possibility of becoming flexible and causing coming off; The earplug of general-purpose type duct hearing aids is designed to circular bowl cup-shaped, and the edge through circular bowl cup-shaped silica gel earplug comes self adaptation applying duct.Appearance makes earplug fully and otocleisis, and outside air can't circulate, and wears for a long time and can feel inaccessible and uncomfortable, serious even pain.
The utility model content
Therefore, to the above-mentioned weak point that general-purpose type duct hearing aids exists, proposed a kind of wear more comfortable, the general-purpose type duct hearing aids of ventilating that gas permeability is also better.
The concrete technical scheme of the utility model is following:
The general-purpose type duct hearing aids that can ventilate comprises a body and earplug, the digital processing chip that is provided with in the body, microphone, battery, receiver; The rearward end of body is provided with battery compartment, microphone opening and backguy; The leading section of body is an earplug interface, and earplug is placed on the earplug interface, and described earplug interface is provided with annular groove; Described earplug is long elliptical profile, is placed on the annular groove of earplug interface.Being different from existing circle because earplug adopts, is the flat formula profile that adopts long elliptical profile, makes earplug not exclusively contact with duct, forms an air duct, more ventilative.
Further, described interface has 2 annular grooves arranged side by side, and earplug also is 2, is placed in respectively on inside and outside 2 annular grooves of earplug interface, and the size of first earplug is slightly larger than the size of second earplug.Adopt two long elliptical profile earplugs can make the difficult drop-off with the fixing firm more of duct of hearing aids.
The utility model adopts as above technical scheme, and the technique effect that has is:
(1) earplug of the duct hearing aids of the utility model adopts the long elliptical profile of prolate, can keep air flow so that button not exclusively contacts with duct, and long-time like this wearing can not feel inaccessible, and pain is worn also more comfortable;
(2) on the earplug interface of the preferred duct hearing aids of the utility model 2 earplugs are arranged; An earplug can be placed into the dark duct near the human body ear-drum; Another earplug then plays main fixation through the Elastic Contact duct, and hearing aids fixes reliable more and difficult drop-off when can guarantee the earplug gas permeability.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Combine accompanying drawing and embodiment that the utility model is further specified at present.
Embodiment 1:
The general-purpose type duct hearing aids of ventilating of present embodiment comprises a body and earplug, the digital processing chip that is provided with in the body, microphone, battery, receiver; The rearward end of body is provided with battery compartment, microphone opening and backguy; The leading section of body is an earplug interface, and earplug is placed on the earplug interface, and described earplug interface is provided with 1 annular groove; Described earplug is long elliptical profile, is placed on the annular groove of earplug interface.
Embodiment 2:
Consult shown in Figure 1; The general-purpose type duct hearing aids of ventilating of present embodiment; Comprise a body 1 and earplug 3, the digital processing chip that is provided with in the body 1, microphone, battery, receiver, the rearward end of body is provided with battery compartment, microphone opening and backguy; The leading section of shell is an earplug interface 2, and earplug 3 is placed on the earplug interface 2.Wherein, Described earplug interface 2 has 2 annular grooves arranged side by side; Earplug 3 also is that the slightly variant earplug of 2 long elliptical profile and size is formed; The size of first earplug 31 is slightly larger than the size of second earplug 32, and first earplug 31 and second earplug 32 are placed in respectively on inside and outside 2 annular grooves 21,22 of earplug interface.
Preferably, the earplug among 2 embodiment is the prolate elliptical profile earplug that adopts the bowl cup-shaped that flexible silica gel processes.More comfortable on wearing, and better with the stationarity of duct, also ventilation more simultaneously.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; Can make various variations to the utility model in form with on the details, be the protection range of the utility model.
