Description

Technical Field

[0001] The utility model relates to the field of hearing aids, in particular to an interference-proof hearing aid. Background Art

[0002] A hearing aid is a small loudspeaker that amplifies sounds that are originally inaudible, and then uses the residual hearing of the hearing-impaired person to send the sound to the auditory center of the brain, allowing the hearing-impaired person to feel the sound, bringing great convenience to the hearing-impaired. Current hearing aids usually have anti-interference functions, which can improve speech clarity and reduce unnecessary background noise interference in noisy environments. By using multiple microphones and combining spatial filtering technology, they can enhance the sound from the speaker's direction while reducing noise from other directions to achieve a better signal-to-noise ratio.

[0003] However, during the use of current hearing aids, the size and shape of the user's auricle may vary greatly, making it impossible for the worn hearing aid to completely match the auricle. At this time, the user may not wear the hearing aid securely, which may lead to the risk of the hearing aid falling off. Therefore, to address the above problem, an anti-interference hearing aid is proposed. Utility Model Content

[0004] In order to remedy the deficiencies of the prior art and avoid the problem that the auricle cannot be expanded and cannot be adapted to the hearing aid, the present utility model proposes an anti-interference hearing aid.

[0006] The adjustment assembly includes a hollow curved rod fixedly installed on the left side of the hearing aid body, a solid curved rod is slidably connected inside the hollow curved rod, a connecting rod is fixedly installed on the surface of the solid curved rod away from the hollow curved rod, an extension body is fixedly installed on the end of the connecting rod away from the solid curved rod, a card slot is provided at the top of the hollow curved rod, a groove is provided at the top of the extension body, a sliding rod is slidably connected inside the groove, and a card block is fixedly installed on the bottom end of the sliding rod.

[0007] Preferably, the right side of the extension body is in adaptive contact with the left side of the hearing aid body, and the slot passes through the top of the hollow curved rod.

[0008] Preferably, the top of the sliding rod and the groove are adapted to be snapped in, and the top of the sliding rod is snapped into the inside of the groove, so that the position of the sliding rod is limited, and the clamping block and the groove are adapted to be snapped in, and the clamping block is snapped into the inside of the groove, so that the position of the hollow bent rod is limited, and at this time the hollow bent rod cannot be further pulled out from the surface of the solid bent rod.

[0009] Preferably, the hearing aid connecting wire passes through the left side of the hearing aid body, the right side of the extension body and the left side of the extension body in sequence and extends to the outside of the extension body. The hearing aid connecting wire transmits the amplified sound received inside the hearing aid body to the eardrum, thereby allowing the user to receive the amplified sound.

[0010] Preferably, the limiting component includes a limiting groove opened on the top of the hearing aid body, a fixing block is fixedly installed on the top of the extension body, an elastic rope is fixedly connected to the right side of the fixing block, and the other end of the elastic rope is fixedly installed with a limiting block.

After the limit block is snapped into the inside of the limit slot, an elastic rope is connected between the hearing aid body and the extension body, thereby preventing the hearing aid body and the extension body from being separated when the user moves with a large amplitude, thereby avoiding inconvenience in use and economic losses.

[0012] The utility model is beneficial in that:

[0013] After the extension body is worn on the top of the auricle, the hearing aid body can be pulled away from the extension body, so that the bottom of the hearing aid body is closely attached to the back of the auricle, thereby allowing the hearing aid body to be firmly placed on the user's ear and avoiding the risk of the hearing aid body falling off the ear.

[0014] After adjusting the position of the extension body, the limit block is snapped into the inside of the limit slot. At this time, an elastic rope is connected between the hearing aid body and the extension body to prevent the hearing aid body and the extension body from separating when the user moves with a large amplitude, thereby avoiding inconvenience in use and unnecessary economic losses.

The block 28 is adapted to be engaged with the groove 25, and the block 28 is engaged with the inside of the groove 25, so that the position of the hollow curved rod 21 is limited. At this time, the hollow curved rod 21 cannot be further pulled out from the surface of the solid curved rod 22. The hearing aid connecting line 3 passes through the left side of the hearing aid body 1, the right side of the extension body 24 and the left side of the extension body 24 in turn and extends to the outside of the extension body 24. The hearing aid connecting line 3 transmits the amplified sound received inside the hearing aid body 1 to the eardrum 4, so that the user can receive the amplified sound.

[0025] Reference Figure 1 and Figure 3 The limiting component 5 includes a limiting groove 51 opened on the top of the hearing aid body 1, a fixing block 52 is fixedly installed on the top of the extension body 24, and an elastic rope 53 is fixedly connected to the right side of the fixing block 52.
