Quiet noise-cancelling earbuds

technical field

The present invention relates to a noise reduction earplug, in particular, to a passive noise reduction type earplug.

Background technique

With the acceleration of the pace of life, people in the city are busy with work and socializing all day, and it is more and more difficult to set aside time to be alone, think or read quietly. The hustle and bustle of the city can easily interrupt the fleeting thoughts. It is easy to make people feel irritable; so noise reduction products came into being, ranging from noise reducers, noise reduction headphones to noise reduction earplugs. The first is an active noise reduction product, which collects and analyzes the sound waves of the external environmental sound, and uses the feedback microphone to send out the inverse sound waves of the environmental sound, so as to cancel the environmental sound and achieve noise reduction; because the collection, analysis, and feedback require certain processing. Therefore, active noise reduction products cannot eliminate sudden and irregular noises; the other is passive noise reduction products, which achieve noise reduction by blocking the transmission of sound. Common products such as earplugs are blocked by earplugs. The ear canal isolates the eardrum from the outside air, so that the external sound cannot enter the human ear from the air, thereby achieving passive noise reduction; therefore, the sealing between the product and the human ear seriously affects the effect of passive noise reduction, and many products blindly The pursuit of sealing makes the earplugs exert greater pressure on the human ear, compressing the microvessels in the ear canal and hindering blood flow; long-term wearing will cause discomfort to the ear and even cause damage to the ear canal.

SUMMARY OF THE INVENTION

In view of the above problems, the present invention provides a silent noise reduction earplug, which has a novel structure and a unique principle. While ensuring the noise reduction effect, it can effectively reduce the stimulation to the ear canal skin and microvessels, and improve the comfort of the ear. , to provide users with a comfortable and quiet meditation space.

In order to solve the above problems, the technical solution adopted in the present invention is: the silent noise reduction earplugs include a soft and elastic plug sleeve and a soothing device placed inside the plug sleeve; A central controller is arranged in the cylinder, and the central controller divides the central control cylinder into two spaces that are not connected to the left and right; the two ends of the central control cylinder are respectively connected with diversion pipes, and the free ends of the diversion pipes are closed; The diversion pipes at both ends of the cylinder are not connected to each other; the inside of the plug sleeve is filled with elastic and closed relief balls, the interior of the relief ball is hollow, and each relief ball is connected to the diversion pipe by bypassing the guiding pipe; one end of the central control cylinder The soothing balls on the guide tube and the soothing balls on the guide tube at the other end of the central control tube are alternately distributed in the plug sleeve; the central control tube, the guide tube and the soothing ball are filled with soothing liquid.

The beneficial effects of the invention are as follows: the plug sleeve is soft and elastic, and will bounce up slowly and return to its original shape after being deformed under pressure; when in use, the user squeezes the plug sleeve into a slender strip and puts it into the ear canal After holding the appropriate depth for a few seconds, the plug sleeve slowly expands, restores its shape, and gradually fills the ear canal. At this time, the plug sleeve isolates the ear canal from the outside world, effectively preventing the air from introducing external noise into the human ear, achieving passive noise reduction. Function: During use, the internal central controller periodically changes the size of the two separated spaces in the central control cylinder, that is, when the space on the left side of the central controller becomes larger, the space on the right becomes smaller, and the space on the right side becomes smaller. When the space on the left becomes larger, the space on the left becomes smaller; when the space on the left becomes larger, the soothing fluid in the soothing ball connected to the space on the left returns to the space on the left through the guide tube and the drainage tube, and the soothing ball shrinks; The space on the right is reduced in volume, and the internal soothing fluid is injected into the soothing sphere connected to the space on the right through the guide tube and the guide tube. These soothing spheres expand and become larger in volume; When the direction changes, the changes of the soothing balls connected to them are opposite; therefore, in the process of periodic adjustment of the central controller, under the premise that the plug sleeve has a sufficient expansion size and can be in close contact with the ear canal, each soothing ball will be adjusted. The staggered expansion and contraction will not cause long-term and continuous compression of the ear canal; therefore, when using the silent noise-cancelling earplugs, there is always enough soothing ball expansion, so as to ensure that the plug cover can effectively block the transmission of sound, and at the same time There is always a soothing bulb that shrinks to relieve the pressure on the ear canal by the plug sleeve, thereby promoting the flow of blood in the ear canal.

The structure can not only ensure effective sound insulation and noise reduction effect, but also can effectively relieve the pressure of earplugs on the ear canal, effectively prevent the blockage of microvessels, and reduce discomfort. , to promote the circulation of blood in the ear canal, open up a quiet space for users in the hustle and bustle of the city, and provide them with a comfortable and quiet meditation moment.

Preferably, each of the diversion tubes is rotationally symmetrically arranged on the outer peripheral wall of the central control cylinder, and adjacent diversion tubes are connected to different ends of the central control cylinder; this structure can improve the complexity of the staggered arrangement of the relief balls and ensure that Adjacent soothing balls will not shrink and expand synchronously, so as to ensure the stability of the plug sleeve.

Preferably, the soothing balls are distributed at 1-3 mm of the lower part of the outer epidermis of the plug cover; the structure size enables the surface of the plug cover to fully respond to the shrinkage and expansion of the soothing balls, thereby improving the effect of massaging and promoting blood circulation.

Preferably, the central controller includes two pieces of memory metal sheets, and the memory metal sheets are airtightly connected to the inner wall of the central control cylinder; the two memory metal sheets are bent and deformed to the left when the temperature is high, and are bent and deformed to the right when the temperature is low; A heating element is arranged between the two metal sheets, and the heating element is powered by a power supply; the power supply periodically energizes and powers off the heating element, so that the two memory metal sheets are periodically bent left and right, and then Change the size of the space on both sides of the central controller, thereby promoting the expansion and contraction of the soothing ball.

The plug cover 1 is soft and elastic, and will bounce up slowly and return to its original shape after being deformed under pressure; when in use, the user squeezes the plug cover 1 into a slender strip, and puts it into the ear canal to a suitable depth for a few seconds. In seconds, the plug sleeve 1 slowly expands, restores its shape and gradually fills the ear canal. At this time, the plug sleeve 1 isolates the ear canal from the outside world, effectively preventing the air from introducing external noise into the human ear, and realizing the passive noise reduction function; During use, the internal central controller 3 periodically alternately changes the size of the two separated spaces in the central control cylinder 2; The two memory metal sheets 31 are periodically bent to the left and to the right, thereby changing the size of the space on both sides of the central controller 3. When the space on the left side of the central controller 3 becomes larger, the space on the right becomes smaller, and the space on the right becomes smaller. When the space is large, the space on the left becomes smaller; specific analysis: when the space on the left becomes larger, the soothing liquid in the soothing ball 5 connected with the space on the left flows back into the space on the left through the guide tube 6 and the guide tube 4, soothing The ball 5 is shrunk; at the same time, the space on the right side is reduced in volume, and the internal soothing liquid is injected into the soothing ball 5 connected with the space on the right side through the guide tube 4 and the guide tube 6, and these soothing balls 5 expand and become larger in volume. ; When the left space and the right space change in the opposite direction, the changes of the soothing balls 5 connected to them are opposite; therefore, during the periodical adjustment of the central controller 3, half of the soothing balls 5 are always shrunk, and the other Half the number of soothing balls 5 are expanded; on the premise that the plug sleeve 1 has a sufficient expansion size and can be in close contact with the ear canal, the soothing balls 5 staggeredly shrink and expand, and there will be no long-term and continuous pressure on the ear Therefore, when using the silent noise reduction earplugs, there is always enough soothing ball 5 to expand, so as to ensure that the plug cover 1 can effectively block the transmission of sound, and at the same time, the soothing ball 5 is always shrunk to relieve the pair of ears of the plug cover 1. Compression of the ear canal, thereby promoting the flow of blood in the ear canal.

This structure can not only ensure effective sound insulation and noise reduction effect, but also can effectively relieve the pressure of earplugs on the ear canal, effectively prevent the blockage of microvessels, and reduce discomfort. Massage, promote the blood circulation of the ear canal, open up a quiet space for users in the hustle and bustle of the city, and provide them with a comfortable and peaceful meditation moment.
