For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] 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.

[0045] Based on this, the utility model provides an ear clip type open hearing aid earphone, which is described in detail through specific embodiments below.

[0046] The utility model provides an ear clip type open hearing aid earphone, referring to Figure 1-Figure 4 As shown, it includes a first shell 1, a front cover 2, a second shell 3, an arc-shaped connecting member 4 and a speaker 5;

[0047] The arc-shaped connecting member 4 includes a flexible shell 41 and a memory elastic member 42, and the flexible shell 41 is sleeved on the memory elastic member 42;

[0048] The flexible shell 41 is connected to the first shell 1 and the second shell 3 respectively, and there is a clamping distance between the first shell 1 and the second shell 3. The first shell 1 and the second shell 3 can be clamped on the auricle under the elastic force of the memory elastic member 42;

[0049] The front cover 2 is clamped on the side of the first shell 1 opposite to the second shell 3, and a first accommodating cavity 6 is formed between the first shell 1 and the front cover 2, and the speaker 5 is accommodated in the first accommodating cavity 6;

[0050] The front cover 2 is provided with a sound outlet 7, and the speaker 5 is connected to the sound outlet 7;

[0051] When the first shell 1 and the second shell 3 are clamped on the auricle, the first shell 1 fits against the cochlea, the second shell 3 fits against the back of the ear, the sound outlet 7 faces the ear canal, and there is a gap between the sound outlet 7 and the ear canal entrance.

[0052] In this embodiment, the flexible shell 41 is relatively soft, and the memory elastic member 42 is shaped into a curved shape and has a shape memory function. The memory elastic member 42 will undergo elastic deformation under the action of external force, so that the arc-shaped connecting member 4 has an elastic clamping force, which can firmly clamp the auricle when the earphone is worn, and because the flexible shell 41 is relatively soft, it will not make the ear uncomfortable, which improves the comfort and will not cause pain even if worn for a long time. The side of the first shell 1 opposite to the second shell 3 is convex, so that it can fit the shape of the cochlea, and the surface of the side of the second shell 3 opposite to the first shell 1 is flat, which can fit the back of the ear, and the volume of the second shell 3 is larger than the first shell 1 to ensure the stability of clamping.

[0053] In this embodiment, refer to Figure 1 and Figure 4As shown, the sound outlet 7 is arranged in the sound emission direction of the speaker 5, and there is a space between the sound outlet 7 and the speaker 5, so that the vibration generated by the speaker 5 drives the surrounding air to generate sound waves, so that the audio signal is converted into audible sound and propagates through the air. Since the sound outlet 7 faces the ear canal and there is a space between it and the ear canal entrance, the sound transmitted by the sound outlet 7 enters the ear canal in an open manner, avoiding potential damage to the eardrum and the external auditory canal, especially protecting the hearing of people with mild to moderate and moderate to severe hearing loss from further damage.

[0054] The ear-clip open hearing aid earphone provided by the embodiment of the utility model, the first shell 1 and the second shell 3 can be clamped in the auricle state under the elastic force of the memory elastic member 42, the clamping force of the memory elastic member 42 is moderate, and has high toughness, which can not only ensure the stability of wearing, but also help to ensure the strength of the earphone. In the clamped state, the first shell 1 fits against the cochlea, and the second shell 3 fits against the back of the ear. Compared with the wearing style of the ear cap blocking the ear canal, the ear swelling and pain caused by the expansion force of the ear cap can be avoided, and the wearing comfort is improved; because the sound outlet 7 is facing the ear canal and has a preset distance from the ear canal, the earphone will not completely close the ear canal, will not cause pressure and discomfort to the ear, avoids potential damage to the eardrum and external auditory canal, helps to protect hearing, and because external sound can enter the ear canal, the wearer can better perceive the surrounding environmental sounds, thereby improving safety.

[0055] In this embodiment, refer to Figure 2-Figure 4 As shown, the first shell 1, the arc-shaped connecting member 4 and the second shell 3 form a C-shaped structure as a whole, and the memory elastic member 42 is deformed by external force, which is convenient for wearing. When wearing, the first shell 1 and the second shell 3 are close to each other, the first shell 1 is located in the cochlea, and the second shell 3 is located at the junction of the back of the auricle and the human head, so that the earphone is small in shape, easy to wear, and not easy to fall. In order to adapt to the auricle, the maximum thickness of the first shell 1 and the second shell 3 are both greater than the thickness of the flexible shell 41, so that the overall earphone is heavy on both sides and light in the middle, which is convenient to wear.

[0056] In a specific embodiment, referring to Figure 1 and Figure 4As shown, the plane where the sound outlet 7 is located and the front face of the speaker 5 (the side opposite to the sound outlet 7) form an angle of 6°-18°, so that the end of the sound outlet 7 close to the ear canal is closer to the speaker 5, while the end close to the arc-shaped connector 4 is farther away from the speaker 5. When the sound is transmitted in the space between the speaker 5 and the sound outlet 7, it will be concentrated in the direction of the ear canal, thereby minimizing the risk of sound leakage, improving the efficiency of sound transmission, and enhancing the clarity of hearing. Preferably, the plane where the sound outlet 7 is located and the front face of the speaker 5 (the side opposite to the sound outlet 7) form an angle of 12°, so that the spatial distribution between the sound outlet 7 and the speaker 5 is more reasonable, further ensuring good sound quality.
