Description

Self-adaptive earplug device and hearing-aid equipment applying same

Technical Field

The invention relates to the field of hearing equipment, in particular to a self-adaptive earplug device and hearing equipment applying the same.

Background

There are many electronic devices, such as hearing aids, that transmit sound energy into the ear canal of a listener through an earplug, and the types of earplugs currently available on the market are generally closed earplugs, open earplugs, custom eardrums, and the like. Each type of earplug has its advantages and disadvantages and a suitable population, where comfort and acoustic performance of the earplug are of the greatest concern.

With the improvement of the auditory protection consciousness of people, many people with mild and moderate hearing impairment can also adopt electronic equipment such as hearing aids or hearing protection earphones, and if the traditional closed earplug is used, the traditional closed earplug can have serious foreign body sensation, stuffy feeling and ear blocking effect, so that the traditional closed earplug is unacceptable for users. The open type earplug is a better method for solving the problems of stuffiness and ear blockage at present, but the earplug does not completely seal the auditory canal, so that the loss of the incoming sound energy is easily caused, and in addition, when the earplug is used in a noisy environment, the external noise is easily leaked into the auditory canal to influence the listening definition, and the acoustic performance is not well ensured.

To this end, a new type of earplug is needed.

An adaptive sound transmission tube assembly 22 is mounted to the earplug body 21, the adaptive sound transmission tube assembly 22 being flexibly connected to the earplug body 21.

The adaptive sound tube assembly 22 includes a sound tube 221, a regulator 222, and a sleeve 223. The sleeve 223 is attached to the earplug body 21, and the sound transmitting tube 221 is fitted inside the sleeve 223 through the adjuster 222. One end of the sleeve 223 extends into the earplug body 21 and the other end extends out of the ear canal 1.

As shown in fig. 2, the earplug body 21 of the present embodiment includes a case 211 and a support strip 212. The supporting bars 212 are disposed inside the housing 211, and at least one supporting bar 212 is 3 supporting bars in this embodiment. The middle of the housing 211 is provided with a mounting post 2111. The support bar 212 has one end connected to the mounting post 2111 and the other end connected to the inner wall of the housing 211. The sleeve 223 is mounted to the mounting post 2111. Thus, the mounting posts 2111 and the support bars 212 can effectively reinforce the strength of the housing 211.

The housing 211 of this embodiment is a flexible housing, and the support bar 212 is an elastic support bar. Therefore, the shell 211 is a circular ring made of silica gel material which can be contacted with the skin of a human body, and the shell 211 made of silica gel material is soft and is easy to be attached to the inner wall of the auditory canal 1; the shell 211 is circular and hollow in the middle, and cannot be completely sealed after being plugged into ears, so that the ear muff is comfortable to wear. The support strip 212 may be a bending strip made of elastic material such as plastic or metal, and when the earplug body 21 is placed in the ear canal 1, the support strip 212 can support the shell 211 and also can deform in cooperation with the deformation of the shell 211, so that the overall shape of the earplug body 21 is matched with the shape of the ear canal 1 of the user.

The outer wall of the regulator 222 is fixedly connected to the sleeve 223 by bonding or the like, and the sound tube 221 is attached to the regulator 222 and penetrates the regulator 222. Thus, the actuator 222 of the present invention may be a ring made of plastic or metal.

The inner wall of the sleeve 223 is formed with a mounting groove 2231, and the mounting groove 2231 is engaged with the adjuster 222. Thus, the mounting slot 2231 facilitates installation and spacing of the adjuster 222.

The adjuster 222 is provided with a second mounting hole 2221, the sound transmission pipe 221 is mounted in the second mounting hole 2221, and the aperture of the second mounting hole 2221 is larger than the outer diameter of the sound transmission pipe 221. Thus, a certain gap is formed between the regulator 222 and the sound transmission tube 221, and the sound transmission tube 221 can freely swing in a certain space inside the sleeve 223.

The invention provides a self-adaptive earplug device 2 with a brand new structure, which comprises the following specific change processes:

the earplug is inserted into the ear → the deformation of the earplug body 21 → the support band 212 presses the first fitting hole 2111a → the deformation of the sleeve 223 → the pressing regulator 222 → the regulator 222 so that the sound transmitting tube 221 is angularly swung inside the sleeve 223 → the direction of the sound outlet is changed.

The specific using process is as follows: insert earplug main part 21 in the duct 1, because earplug main part 21 is whole soft, can warp along with duct 1, the 1 foreign body sensation in the greatly reduced duct, earplug main part 21 incompletely seals the duct 1, obviously improves the vexed and stifled ear effect of ear. As the earplug body 21 deforms, the first mounting hole 2111a is pulled by the support band 212 to deform, which causes the sleeve 223 of the adaptive sound transmission tube assembly 22 to deform, and the internal actuator 222 is actuated, so that the sound transmission tube 221 swings at a certain angle inside the sleeve 223, which can change the direction of the sound outlet to make the sound follow the direction of the ear canal 1 to be transmitted into the ear, which is a significant help for the user to listen to the sound signal. Therefore, the adaptive earplug apparatus 2 of the present invention can ensure wearing comfort and improve listening quality.
