Description

Multifunctional noise reduction earphone

Technical Field

The invention relates to the technical field of earphone accessories, in particular to a multifunctional noise reduction earphone.

Background

Earphones are common entertainment products for people, and are divided into music earphones, noise reduction earphones, sports earphones and the like according to functions; the noise reduction earphone mainly plays a role in eliminating external noise and creates a quiet and pure music space for a user, and is divided into active noise reduction and passive noise reduction, wherein the active noise reduction collects the noise of an external environment through collecting wheat, and the noise of the external environment is counteracted by analyzing and emitting reverse sound waves; the passive noise reduction reduces the transmission of noise by blocking a transmission channel of an external space;

however, in the prior art, complete isolation of sound is often pursued for the use of the noise reduction earphone, in real life, particularly when the user walks on a busy road surface, the completely sound-proof earphone may cause great potential safety hazard in use, and the commonly used noise reduction earphone generally adopts an in-ear structure, and after the earphone is used for a long time, the ear may be uncomfortable, so that the ear is red and swollen, and the heating phenomenon is generated.

Disclosure of Invention

The invention aims to solve the problem that traffic safety can be caused when a noise reduction type earphone in the prior art is used and is isolated from external sound, and adverse effects are generated on ears after long-time use, and provides a multifunctional noise reduction earphone.

In order to achieve the purpose, the invention adopts the following technical scheme: a multifunctional noise-reducing earphone comprises a shell, wherein a sucker is fixedly connected to one end of the shell, an arc-shaped layer is fixedly connected to one end, away from the sucker, of the shell, a pressure rod is arranged in the center of the arc-shaped layer, a foam metal plate is arranged on one side, away from an arc-shaped surface, of the arc-shaped layer, a shell is fixedly connected to the center of the shell, a loudspeaker is arranged in the shell and connected with an earphone cord, a fixing box is sleeved outside one end of the shell, a fixing layer is sleeved on the other end of the shell, the fixing layer is fixedly connected with the outer wall of the fixing box, and one end, close to the sucker, of;

the fixed box is close to one side of the foam metal plate and is connected with a pressing plate in a sealing and sliding mode, the pressing plate is fixedly connected with a pressing rod, a spring is fixedly connected onto the pressing plate, the other end of the spring is fixedly connected with the casing, the casing penetrates through the inner wall of the fixed box and is connected with the fixed box in a sealing and sliding mode, and the fixed layer is made of an intelligent polymer gel material.

In above-mentioned multi-functional earphone of making an uproar that falls, the earphone cord runs through the inner wall of fixed box and shell simultaneously, the intercommunication is equipped with a chemical valve and a check valve in fixed box and the fixed layer, the chemical valve adopts intelligent polymer gel material, fixedly connected with annular current conducting plate in the fixed box, the current conducting plate electricity is connected with a plurality of centrifugal impellers, centrifugal impeller fixed connection is in the clearance of shell and fixed box.

Compared with the prior art, the invention has the advantages that:

1. in the invention, the shell is fixedly connected with the sucker and used for fixing the whole earphone outside the auditory canal, the shell and the fixing layer can be plugged into the auditory canal to fix the earphone, and in the process, the pressing plate compresses the space in the fixing box by pushing the pressing rod connected with the arc-shaped surface, and the gas is pressed into the fixing layer by the one-way valve, so that the fixing layer expands and is matched with the auditory canal of a corresponding user, and the problem of unmatched size can be avoided;

2. when the arc-shaped surface is pressed, the pressing rod acts on the pressing plate, the pressing rod acts on the piezoelectric sheet on the arc-shaped surface, so that the piezoelectric sheet generates a small current, the magnetorheological fluid in the arc-shaped layer is converted into the Bingham body characteristic with high viscosity and low fluidity, and the magnetorheological fluid is pushed into the gap of the foam metal plate by the arc-shaped surface while the pressing rod acts on the pressing plate, so that the gap is completely filled, and the interference of external noise on the earphone is isolated;

3. under normal noise, the magnetorheological fluid is filled in the foam metal plate to completely isolate sound, and when the external noise is too large and is similar to the sound of a whistling of an automobile; the piezoelectric patches who inlays in the arcwall face at this moment will vibrate under the sound wave effect, and the foam metal sheet vibration of drive thin layer, make the spring electrified and make self take place the shrink on the one hand, withdraw the casing initiative from user's duct, on the other hand makes the magnetorheological suspensions in the gap will break away from among the foam metal sheet, make the foam metal sheet only play and fall the noise, and can not produce syllable-dividing, make external noise pass through the clearance in shell and the casing and get into the duct, and be accepted by the user together with the sound of earphone broadcast itself, avoid appearing the traffic safety problem, perhaps called and can't hear clearly by the relative loud sound.

4. Meanwhile, the fixing layer is made of a thermal shrinkage material, namely, when the auditory canal generates heat due to red swelling, the fixing layer can contract inwards at the moment, so that a shell entering the auditory canal is pushed to be recovered, and expanded gas in the fixing layer is pushed out through a chemical valve arranged on an intelligent polymer gel material, so that the phenomenon that the ear is inflamed or discomfortable due to long-time use of the earphone is avoided;

5. after casing and fixed layer withdraw from the duct, the casing other end and the contact of current conducting plate this moment for the connection of current conducting plate intercommunication and micro battery makes the impeller in the shell begin to rotate, through output centrifugal force on the one hand, makes the sucking disc inseparable with the duct outside is fixed, still keeps the stable of earphone fixed under the state that the casing does not go into the duct, and on the other hand is through accelerating the air current flow, makes the near red and swollen phenomenon of environment duct.

6. After the temperature of the auditory canal is recovered, the original area of the fixing layer made of the heat-shrinkable material is recovered, and the shell is plugged into the auditory canal again under the action of the spring, so that the earphone can be used for reducing noise normally.
