In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0054] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] The inventors have discovered that when the existing bean-type or rod-type hearing aids on the market are worn by users, the ear caps block the ear canal for a long time. After long-term wearing, the ears will feel swollen and painful due to the expansion force of the ear caps. In addition, since hearing aids are mainly suitable for people with mild to moderate or moderate to severe hearing loss, blocking the ear canal for a long time will further damage the hearing.

[0056] Based on this, the utility model provides an ear-hook open auxiliary hearing headset, which is described in detail through specific embodiments below.

[0057] The utility model provides an ear-hook type open auxiliary listening headset, referring to Figure 1-Figure 5 As shown, it includes a first shell 1, a second shell 2, an ear hook 3 and a speaker 4;

[0058] The first shell 1 is connected to the second shell 2;

[0059] The speaker 4 is fixed to the inner side of the second housing 2;

[0060] The second housing 2 is provided with a sound outlet 5, and the sound-emitting surface of the speaker 4 faces the sound outlet 5 and is parallel to the sound outlet 5;

[0061] The longitudinal length of the sound outlet 5 is greater than the lateral length of the sound outlet 5 , and the area of ​​the sound outlet 5 is smaller than the area of ​​the sound emitting surface of the speaker 4 ;

[0062] The ear hook 3 is connected to the first shell 1 and the second shell 2 respectively, and the ear hook 3 is bent and extended in a direction away from the second shell 2 so that there is a preset distance between the sound outlet 5 and the ear hook 3 .

[0063] When the earhook open hearing aid earphone is worn on the human auricle, the earhook 3 is tightly attached to the ear root, the second shell 2 partially abuts against the cochlea, the sound outlet 5 faces the ear canal, and there is a gap between the sound outlet 5 and the entrance of the ear canal.

[0064] In this embodiment, refer to Figure 1-Figure 2 As shown, the ear hook 3 bends and extends from the first shell 1 and the second shell 2 in a direction away from the second shell 2, so that there is a preset distance between the end of the ear hook 3 away from the second shell 2 and the sound outlet 5, instead of being pressed against the outside of the sound outlet 5 or the second shell 2, so that when the ear-hook open hearing aid earphone is worn, the clamping force on the auricle is moderate, which not only ensures the stability of the ear-hook open hearing aid earphone, but also ensures the comfort of long-term wearing. In addition, because there is a preset distance between the end of the ear hook 3 away from the second shell 2 and the first shell 1, the second shell 2 can partially abut the cochlea instead of completely blocking the entrance to the ear canal, so that a gap can be left between the sound outlet 5 and the entrance to the ear canal, which can prevent the ear canal from being completely closed, thereby effectively preventing potential damage to the eardrum and external auditory canal, and helping to protect hearing.

[0065] In this embodiment, refer to Figure 2 and Figure 3 As shown, the sound-emitting surface of the speaker 4 is parallel to the sound outlet 5, and the area of ​​the sound outlet 5 is smaller than the area of ​​the sound-emitting surface of the speaker 4, which is conducive to the direct conduction of sound and the reflection propagation, thereby improving the sound quality. The longitudinal length of the sound outlet 5 is greater than the lateral length of the sound outlet 5, which can reduce the lateral diffusion of sound, further allowing the sound to be concentrated toward the ear canal, thereby improving the clarity of the sound heard by the wearer. By leaving a gap between the sound outlet 5 and the entrance of the ear canal and concentrating the sound toward the ear canal, the ear-hook open hearing aid can not only protect hearing, but also avoid using a high volume due to unclear sound, making it more suitable for people with mild to moderate and moderate to severe hearing loss.
