Description

MRI earphone specials

Technical field

The utility model is related to magnetic resonance equipment technical field, more particularly to a kind of MRI (Magnetic Resonance Imaging, magnetic resonance imaging) earphone special.

Background technology

It is well known that due to the particularity of magnetic resonance examination room strong magnetic field circumstance, common earphone is under magnetic resonance environment Strong electromagnetic interference can be subject to, it is impossible to normally use, thus, need badly and produce one kind and can normally be used under magnetic resonance environment Earphone.

Utility model content

The purpose of this utility model there are provided a kind of MRI earphone specials, and it can normally be used under magnetic resonance environment.

What the utility model was realized in：

A kind of MRI earphone specials, including head hoop and the two relative auricular conchas located at the head hoop two ends, each auricular concha Built-in piezo assembly, each piezo assembly includes piezo pedestal, installs in the piezo pedestal Piezo and wrap up the first copper mesh radome of the piezo pedestal.

Used as the improvement of above-mentioned MRI earphone specials, the piezo pedestal includes the piezo bottom with piezo mounting groove Seat and lid set the piezo lid of the piezo mounting groove, and the bottom wall of the piezo mounting groove is provided with some perforates.

Used as the improvement of above-mentioned MRI earphone specials, each auricular concha also includes installing the ear of the piezo assembly Hood shell, lid set the cavernous body of the piezo assembly and cover the ear for setting the piezo assembly and the cavernous body Circle, the earphone enclosure shell is rotated with the respective end of the head hoop and is connected.

As the improvement of above-mentioned MRI earphone specials, also including being covered with the trident connecting line and trident PU of copper shield (Polyurethane, polyurethanes) is managed, and the trident connecting line is built in the trident PU pipes, the trident connection Line includes electrical tip side and two terminals being respectively connected in auricular concha described in two.

Used as the improvement of above-mentioned MRI earphone specials, also including headset, the headset is fixedly arranged on trident connecting line described in Intersection, and the pickup hole of the headset is covered with the second copper mesh radome.

The beneficial effects of the utility model are：The MRI earphone specials that the utility model is provided, its two auricular concha difference is built-in Piezo assembly include piezo pedestal, install in the piezo in piezo pedestal and parcel piezo pedestal first Copper mesh radome, by effective shielding of the first copper mesh radome so that the loudspeaker output of auricular concha will not be subject to electromagnetic interference, So that this MRI earphone specials can normally be used under magnetic resonance environment.

Brief description of the drawings

In order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art, below will be to embodiment Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only It is some embodiments of the present utility model, for those of ordinary skill in the art, before creative labor is not paid Put, other accompanying drawings can also be obtained according to these accompanying drawings.

Fig. 1 is a kind of structural representation of preferred embodiment of the utility model MRI earphone specials.

Fig. 2 is the fractionation structural representation of MRI earphone specials shown in Fig. 1.

Fig. 3 is the fractionation structural representation of the piezo assembly of MRI earphone specials shown in Fig. 1.

Specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.

As shown in Figure 1, Figure 2 and Figure 3, the present embodiment provides a kind of MRI earphone specials 1, and MRI earphone specials 1 include head hoop 11 and two relatively located at the auricular concha 12 at the two ends of head hoop 11, the built-in piezo assembly 121 of each auricular concha 12, each piezo Assembly 121 includes piezo pedestal 1211, installs in the piezo 1212 in piezo pedestal 1211 and parcel piezo First copper mesh radome 1213 of pedestal 1211.

In the present embodiment, as shown in figure 3, piezo pedestal 1211 is included with piezo mounting groove (not indicated in figure) Piezo base 12111 and lid set the piezo lid 12112 of piezo mounting groove, and the bottom wall of piezo mounting groove is provided with some Perforate.As shown in Fig. 2 each auricular concha 12 also includes that installing the earphone enclosure shell 122 of piezo assembly 121, lid sets piezo The cavernous body 123 and cover of assembly 121 set the ear circle 124 of piezo assembly 121 and cavernous body 123, earphone enclosure shell 122 Rotated with the respective end of head hoop 11 and be connected.

This MRI earphone specials 1 also include that trident connecting line (not shown) and trident the PU pipe for being covered with copper shield (are not schemed Show), trident connecting line is built in trident PU pipes, and trident connecting line is respectively connected to two auricular conchas 12 including electrical tip side and two In terminals.This MRI earphone specials 1 also include headset (not shown), and headset is fixedly arranged on the intersection of a trident connecting line, and The pickup hole of headset is covered with the second copper mesh radome, by the structure setting of the headset, is being capable of achieving this MRI earphone specials 1 just Chang Shengyin is input into.

The MRI earphone specials that the present embodiment is provided, its two auricular concha distinguishes built-in piezo assembly includes buzzing bar Body, the first copper mesh radome for installing in the piezo in piezo pedestal and wrapping up piezo pedestal, by the first copper mesh Effective shielding of radome so that the loudspeaker output of auricular concha will not be subject to electromagnetic interference so that this MRI earphone specials can be in magnetic Normally used under resonance environment.

Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model Protection domain within.
