Abstract

The utility model relates to an electromagnetic wave preventing and sound conducting earphone, which is used for the existing mobile phones and personal stereos. The utility model is characterized in that a sound conducting pipe is a hollow soft pipe, a bundling sleeve is arranged and fixed at the front end of the sound conducting pipe and an ear plug is arranged and fixed at the tail end of the sound conducting pipe; the bundling sleeve is sheathed on a loudspeaker of the earphone to guide the sound wave which is generated by the utility model to be transferred to the ear plug through a sound conducting pipe. When users put the ear plug into their ears, the sound of the earphone can be heard clearly to achieve the effect that the electromagnetic wave is prevented from approaching human bodies. The utility model is suitable for the mobile phone to prevent the electromagnetic wave.

Description

Anti electromagnetic wave acoustic earphone

The utility model relates to a kind of earphone, relates in particular to a kind of anti electromagnetic wave acoustic earphone.

Well known electrical appliance, under user mode, all can send electromagnetic wave, especially the electromagnetic wave that sent of mobile phone on-state more exceeds general electrical equipment several times, the excessive electromagnetic effect of this kind confirms harmful through science, be to be one of human body carcinogenic factor, just the mobile phone purpose is being carried convenient the use, and must be close to the electrical equipment that ear is listened to the other side's sound when connecting, and then electromagnetic wave is difficult to avoid for the influence of human body.

A kind of earphone design (being commonly called as handfree receiver unit) of mobile phone is proposed for this reason, its selected end in electric wire is provided with an inserting terminal, this electric wire other end then is installed with the little loud speaker that can fill in the ear, inserting terminal can be located at mobile phone for the user, and little loud speaker is filled in the ear, is sent the sound of mobile phone by little loud speaker; Can avoid high electromagnetic mobile phone in conversation for the user, the design of this kind earphone can be talked with by Handless when driving, and this kind makes things convenient for effect obvious to all.

But existing earphone in use in fact still can send a certain amount of electromagnetic wave, is not to reach not have the effect that electromagnetic wave is right after influences human body fully, and is then bigger to the human influence as long-term use earphone.Therefore, this case creator is the professional experiences with design, manufacturing loud speaker Related product, a kind of anti electromagnetic wave acoustic earphone design is proposed, it utilizes hollow tube to have the acoustic characteristic, cooperating with general earphone becomes a new Headphone structure, utilize acoustic earphone of the present utility model that sound collecting is passed to listen in the ear and read, reach effective eliminating electromagnetic wave near human body, and the result of use that makes things convenient for of possessing mobile phone or walkman simultaneously.

Main purpose of the present utility model is to overcome the prior art deficiency, and a kind of anti electromagnetic wave acoustic earphone is provided.

For this reason, the utility model provides a kind of anti electromagnetic wave acoustic earphone, mainly is made of an earphone and a voice conducting pipe, earphone includes a loud speaker, loud speaker one side also is connected with an electric wire, and connects in the wire terminations place and to establish an inserting terminal, described voice conducting pipe, be a kind of hollow form flexible pipe, front end in voice conducting pipe is provided with a collar, and collar is an elasticity ware shape, establishes a projection in outer back side central authorities, make the middle endoporus of projection just communicate with ware shape collar, projection plugs into the voice conducting pipe front end; Be installed with a soft earplug in the voice conducting pipe end, offer a through hole in the earplug end; The ware shape collar of described voice conducting pipe is sheathed on the loud speaker outside of earphone, by collar the loud speaker periphery is coated.

In the utility model, the electric wire chosen place of this earphone can be established a microphone.

In the utility model, the electric wire place of this earphone can establish a clip.

In the utility model, this voice conducting pipe chosen place can be established a clip.

In the utility model, can establish a hook under the earplug of this voice conducting pipe.

Advantage of the present utility model and effect are: cooperate existing earphone with a kind of flexible pipe with acoustic characteristic, constitute an anti electromagnetic wave acoustic earphone, the sound wave that loud speaker sends that has earphone now can be imported in the ear by this flexible pipe, loud speaker needn't be established in the ear, reaches the effect of complete anti electromagnetic wave near human body; Electric wire place under the loud speaker of the present utility model can set up a microphone, and mobile phone user can carry out the Handless dialogue; The chosen place of acoustic flexible pipe of the present utility model is provided with a hook, the user can conveniently the earplug of acoustic hose end be established pleasant in, and prevent that earplug from coming off.

Now in conjunction with the accompanying drawings the utility model is described in detail as follows:

As shown in Figures 1 and 2, the anti electromagnetic wave acoustic earphone that the utility model is done, it comprises that mainly an earphone 1 and a voice conducting pipe 2 constitute, wherein:

One earphone 1, it is a kind of existing Headphone structure, mainly has a loud speaker 11, loud speaker 11 1 sides also are connected with an electric wire 12, and connect in electric wire 12 ends and to establish an inserting terminal 13, one voice conducting pipe 2, be mainly the hollow form flexible pipe that a kind of soft plastic or rubber constitutes, select in the front end of voice conducting pipe 2 and be provided with a collar 21, this collar 21 is for having elasticity ware shape, be provided with a projection 211 in outer back side central authorities, make the endoporus 212 in the middle of the projection 211 just communicate with ware shape collar 21, this projection 211 can plug into voice conducting pipe 2 front ends; Select the soft earplug 22 that is installed with a hollow form in the end of voice conducting pipe 2 again, offer a through hole 221 in the side of this earplug 22;

Thus, (as shown in Figure 3) can utilize the ware shape collar 21 of above-mentioned voice conducting pipe 2 front ends to be loud speaker 11 outsides and the tight bundle that flexibly is sheathed on earphone 1, by this collar 21 loud speaker 11 is gone out the peripheral coating of part, to make this voice conducting pipe 2 mutually combine, form anti electromagnetic wave acoustic earphone of the present utility model with this with earphone 1.

User mode of the present utility model, (as shown in Figure 4) user can select the inserting terminal 13 of earphone 1 to be inserted in the microphone aperture (MIC) of general mobile phone 3, with this in mobile phone 3 on-states, with the earplug 22 of voice conducting pipe 2 establish pleasant in, when the loud speaker 11 of this earphone 1 sends sound wave, can sound wave be passed in the ear, clearly to listen to message by voice conducting pipe 2 and earplug 22, and with loud speaker 11 not near the structure of ear, reach the effect that prevents that fully electromagnetic wave is close; (as shown in Figure 5) user also can select the utility model is applied to general walkman 4, reaches above-mentioned same effect.

Moreover, (as shown in Figure 6) wherein the selected appropriate locations of electric wire 12 of this earphone 1 also can set up a microphone 14, provide the user when using mobile phone, can engage in the dialogue with this microphone 14, reach the effect that makes things convenient for of Handless.(as shown in Figure 7) the utility model also can be established a clip 15 in electric wire 12 places or voice conducting pipe 2 places of earphone 1 again, and the utility model is fixed on the clothes; And the earplug of this voice conducting pipe 2 also can select to set up a hook 23 for 22 times, allows user's hook be located at the ear upper limb with this hook 23, and earplug 22 is inserted in the ear, and reaches and prevent the effect that comes off.
