Abstract

The utility model discloses a standard ear canal machine which comprises an engine casing, a loudspeaker, a microphone, a sound intensifier, an ear mould head, a connecting head and a battery bin, wherein the loudspeaker is mounted at the inner end of the inner cavity of the engine casing near to human ear; the microphone is mounted at the outer end of the inner cavity of the engine casing; the battery bin is arranged in the engine casing; and the inner end of the standard engine casing is connected with the ear mould head through the connecting head. The casing of the machine is formed by three parts: the engine casing, the ear mould head and the connecting head, the engine casing is connected with the ear mould head through the connecting head, the engine casing serves the same functions with the casing of a common ear canal machine and is used for the installation of loudspeaker and microphone, and the ear mould head used for being inserted into ear can be made into different sizes in the utility model so as to meet the requirements of customers with different ear canal sizes, therefore, the standard ear canal machine has the advantages of high generality, no need of being manufactured by single piece, capability of being produced in batch and low manufacturing cost.

Description

Standard duct machine

Technical field

The utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of standard duct machine.

Background technology

The duct machine is the equipment that is used for compensator's hearing, and it can help the relatively poor crowd of hearing to compensate hearing.The duct machine of commonly using (as shown in Figure 1) is made up of casing, loudspeaker, microphone, sound intensifier (as: chip), battery compartment, loudspeaker 2 ' and microphone 3 ' all are installed in the shell 1 ', and the inner 11 ' of shell 1 ' is made into the shape that the duct with the people adapts.This duct machine of commonly using is an overall structure, and it is to offer special ear mold according to different clients' duct to produce shell 1 ', thereby has following defective:

1, the duct size difference that is used for the client needs to do corresponding shell (auricular concha) shape according to the ear sample of getting the client, and the manufacturing cycle is long, and not can manufacture.

2, the measurement of shell (auricular concha) overall dimension all needs the doctor of comparison specialty and tests and join Shi Caineng and finish the cost height.

3, effect is bad, stifled ear.

The utility model content

The standard duct machine that the purpose of this utility model is to provide a kind of versatility height, can produces in batches, sound effect is good.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of standard duct machine, and it comprises casing, loudspeaker, microphone, sound intensifier (as: chip), battery compartment; Described loudspeaker are installed in chassis cavity, in the duct of people's ear, microphone is installed in the outer end of chassis cavity, on the external auditory meatus or cavity of concha of people's ear, and battery compartment is set in casing; It also comprises ear mold head and connector, and the inner of described casing is connected with the ear mold head by connector.

Described connector has a hollow channel, the two ends of this connector be plugged in the central passage of ear mold head respectively and the inner through hole of casing in, the inner through hole of this casing is over against the loudspeaker that are installed in chassis cavity, and the through hole of the central passage of ear mold head, the hollow channel of connector and casing the inner forms the sound channel that tucket can be imported into people's ear.

Described connector is made by special material, and the abutting end of the ear mold head that itself and flexible material are made has an outer groove, and the last cell wall of this outer groove can insert the central passage of ear mold head and holding on the inner groove on the ear mold head central passage.

After adopting such scheme, because the utility model shell is made up of standard casing, ear mold head, connector three parts, casing couples together by connector and ear mold head, and the function of casing is identical with the shell of commonly using the duct machine, is used to install loudspeaker and microphone etc., and the ear mold head that will insert people's ear is made the ear mold head with multiple overall dimension, thereby can satisfy the demand with different duct size clients, the versatility height need not the single-piece manufacturing, can produce low cost of manufacture in batches.And because ear mold head flexible material commonly used makes, worn more comfortable, sound effect good, perhaps make open ear mold head and eliminate stifled ear effect.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Description of drawings

Fig. 1 is a structural representation of commonly using the duct machine;

Fig. 2 is a three-dimensional exploded view of the present utility model;

Fig. 3 is an installation diagram of the present utility model;

Fig. 4 is the utility model connector and ear mold head connection layout.

Embodiment

As Fig. 2, shown in Figure 3, the utility model is a kind of standard duct machine, and it mainly is made up of casing 1, ear mold head 2, connector 3, loudspeaker 4, microphone 5, battery compartment 6, sound intensifier 7.

Described loudspeaker 4 are installed in casing 1 inner chamber and are positioned near people's duct the inner 11, and microphone 5 is installed in the outer end of casing 1 inner chamber, on the external auditory meatus or cavity of concha of people's ear, and battery compartment 6 is set in casing 1; The inner of described casing 1 is connected with ear mold head 2 by connector 3.Described sound intensifier 7 (as: chip) is installed in the casing 1.

Described connector 3 has a hollow channel 31, the two ends of this connector 3 are plugged on respectively in the central passage 21 of ear mold head 2 and in the casing 1 inner through hole 12, this casing 1 inner through hole 12 is over against the loudspeaker 4 that are installed in casing 1 inner chamber, and the through hole 12 of the central passage 21 of ear mold head 2, the hollow channel 31 of connector and casing 1 the inner forms the sound channel that loudspeaker can be imported into people's ear for 4.

As shown in Figure 4, described connector 3 is made by special material, the abutting end that itself and ear mold head 2 flexible materials (as: rubber) are made has an outer groove 32, and the last cell wall 33 of this outer groove 32 can insert the central passage 21 of ear mold head 2 and holding on the inner groove 22 on ear mold head 2 central passages 21.

During use, will be inserted by connector 3 upper ends that special material is made and be made in ear mold head 2 central passages 21 by flexible material, outer groove 32 holdings of connector 3 are on the inner groove 22 on ear mold head 2 central passages 21; Again connector 3 lower ends are inserted the through hole 12 of casing 1 the inner.

Emphasis of the present utility model just is: be provided with the ear mold head that can satisfy different duct size clients and the casing of standard, and couple together by connector.

The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
