DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In order to solve the problem that in the prior art, a waterproof breathable membrane is provided at the position of the sound hole of the hearing aid, but the waterproof breathable membrane covers the sound hole, which undoubtedly affects the sound emission and may weaken the sound emission, this embodiment provides the following technical solutions:

[0025] See also Figure 1-4A hearing aid with good waterproof effect provided in this embodiment includes a hearing aid body 6, a connecting block 8 is arranged on the hearing aid body 6, a sound outlet piece 9 is arranged at one end of the connecting block 8 away from the hearing aid body 6, a sound outlet hole 10 is opened on the sound outlet piece 9, a water drop-shaped flow block 14 is arranged on the inner wall of the sound outlet hole 10, a waterproof film 13 is arranged on the outer surface of the water drop-shaped flow block 14, a sealing gasket 5 is arranged on the hearing aid body 6, a connecting wire 4 is arranged on the sealing gasket 5, a battery installation compartment 3 is arranged at one end of the connecting wire 4 away from the sealing gasket 5, the sound outlet hole 10 The water drop-shaped flow block 14 arranged on the inner wall will reduce the aperture of the inner wall of the sound-releasing hole 10, but will not block the transmission of sound in the sound-releasing hole 10. In addition, due to the special shape of the flow block, the wider end will prevent the entry of sweat or liquid, while the thinner end at the rear end will not reduce the volume of the sound transmitted. In addition, a waterproof membrane 13 is arranged on the inner wall of the sound-releasing hole 10, which can also prevent liquid from entering the hearing aid body 6 along the sound-releasing hole 10. The arrangement of these structures not only improves the waterproofness of the hearing aid body 6, but also does not affect the volume of normal sound of the hearing aid body 6.

[0026] In this embodiment, reference Figure 1 A rubber ear hook structure 1 is provided on the battery installation compartment 3, and the rubber ear hook structure 1 is adhesively connected to the battery installation compartment 3. An auricle reinforcement sheet 2 is provided on the rubber ear hook structure 1, and the auricle reinforcement sheet 2 and the rubber ear hook structure 1 are integrally provided. When the user inserts the hearing aid body 6 into the external auditory canal, the rubber ear hook structure 1 is hung behind the ear, and the auricle reinforcement sheet 2 is covered on the auricle, so as to prevent the hearing aid body 6 from slipping out of the ear canal and falling on the ground due to the bumps caused by the movement of the person in the ear canal, thereby causing damage to the hearing aid body 6;

[0027] In this embodiment, reference Figure 3 The hearing aid body 6 is provided with an anti-skid pattern 7, which is integrated with the hearing aid body 6. The outer surface of the hearing aid body 6 is covered with the anti-skid pattern 7 in a rhombus shape. When the user holds the hearing aid body 6, the fingertips contact the outer surface of the hearing aid body 6, and the rough anti-skid pattern 7 increases the friction between the fingertips and the hearing aid body 6 to prevent slipping. In addition, the anti-skid pattern 7 is only provided at the position where the hearing aid body 6 does not extend into the external auditory canal, and will not scratch the external auditory canal.

[0028] In this embodiment, reference Figure 3The connecting block 8 is provided with an anti-slip rubber sleeve 11, which is sleeved with the connecting block 8. When the user wants to insert the hearing aid body 6 into the ear canal, the anti-slip rubber sleeve 11 is squeezed by the inner wall of the ear canal to deform, and the anti-slip rubber sleeve 11 wraps the sound outlet piece 9 on the connecting block 8, thereby increasing the friction between the hearing aid body 6 and the ear canal to prevent it from being easily lifted out, and the anti-slip rubber sleeve 11 can fill the gap between the hearing aid body 6 and the ear canal, thereby playing a role in reducing external noise;

[0029] In this embodiment, reference Figure 3 The anti-slip rubber sleeve 11 is provided with an anti-slip extension piece 12, which is integrally provided with the anti-slip rubber sleeve 11. When the anti-slip rubber sleeve 11 is inserted into the ear canal and contacts the inner wall of the ear canal, the anti-slip extension piece 12 is provided so that the anti-slip extension piece 12 is squeezed by the ear canal with a greater force because the diameter of the anti-slip extension piece 12 is larger than that of the anti-slip rubber sleeve 11, thereby further strengthening the firmness of the connection between the anti-slip rubber sleeve 11 and the inner wall of the ear canal;

[0030] Working principle: A connection block 8 is provided on the hearing aid body 6, and a sound outlet piece 9 is provided at the end of the connection block 8 away from the hearing aid body 6, and a sound outlet hole 10 is opened on the sound outlet piece 9, and a water drop-shaped flow block 14 is provided on the inner wall of the sound outlet hole 10, and a waterproof film 13 is provided on the outer surface of the water drop-shaped flow block 14. A sealing gasket 5 is provided on the hearing aid body 6, and a connecting wire 4 is provided on the sealing gasket 5. A battery installation compartment 3 is provided at the end of the connecting wire 4 away from the sealing gasket 5. The water drop-shaped flow block provided on the inner wall of the sound outlet hole 10 14 will reduce the aperture of the inner wall of the sound hole 10, but will not block the transmission of sound in the sound hole 10, and due to the special shape of the baffle, the wider end will prevent the entry of sweat or liquid, while the rear end is the thinner end and will not reduce the volume of the sound transmission, and a waterproof membrane 13 is provided on the inner wall of the sound hole 10, which can also prevent liquid from entering the hearing aid body 6 along the sound hole 10. The arrangement of these structures not only improves the waterproofness of the hearing aid body 6, but also does not affect the volume of normal sound of the hearing aid body 6.
