[0025] The present invention provides a deep ear canal Bluetooth hearing aid. Figures 1 to 3 This is a specific embodiment of the deep ear canal Bluetooth hearing aid provided by the present invention.

[0026] Referring to Figures 1 to 3 , the deep ear canal Bluetooth hearing aid includes a housing 1. One end of the housing 1 is provided with a holding member 2. A main board 13 is arranged inside the housing 1. An antenna assembly 3 is arranged on the main board 13. The antenna assembly 3 includes an external antenna unit 31. The external antenna unit 31 and the holding member 2 are arranged as an integrated structure.

[0027] A contact block 21 is arranged on the holding member 2. A contact groove 111 that abuts against the contact block 21 is arranged on the inner wall of the housing 1.

[0028] In this embodiment, by integrating the external antenna unit 31 with the holding member 2, the Bluetooth signal strength of the antenna assembly 3 is ensured, and the external structure of the housing 1 is made simple and more beautiful. In the existing deep-ear canal Bluetooth hearing aids, the pull cord is usually fixed to the housing, and the pull cord cannot be disassembled, which is not convenient for cleaning and maintenance. Moreover, the pull cord is usually small, and the connection between the pull cord and the housing is not stable enough, posing a risk of breakage. In this embodiment, the holding member 2 is passed through the housing 1, making the holding member 2 detachable from the housing 1, facilitating disassembly for cleaning, replacement, etc. And through the abutment between the abutting block 21 and the abutting groove 111, a large contact area is provided between the holding member 2 and the housing 1, which can reduce stress concentration and improve the load-bearing capacity of the holding member 2.

[0029] Further, the holding member 2 is sleeved outside the external antenna unit 31. In this embodiment, the holding member 2 is arranged to wrap the external antenna unit 31. The external antenna unit 31 can be protected by the holding member 2, and at the same time, the overall appearance consistency can be improved, making it more beautiful.

[0030] The housing 1 includes a bottom shell 12 and a face shell 11 that are snap-fitted together, and the holding member 2 is passed through the face shell 11. In this embodiment, the housing 1 is set as a detachable bottom shell 12 and face shell 11, allowing the user to open the housing 1, which is convenient for inspection, replacement, and repair of internal components, reducing the maintenance cost and time. Specifically, the bottom shell 12 is provided with an annular groove for the face shell 11 to snap into. The face shell 11 is snap-fitted with the annular groove of the bottom shell 12. This setting makes the installation and disassembly of the face shell 11 and the bottom shell 12 convenient and can also achieve a seamless connection between the face shell 11 and the bottom shell 12, making the product appearance more neat and beautiful.

[0031] Further, the antenna assembly 3 further includes an internal antenna unit 32 connected to the external antenna unit 31, and a strip-shaped groove 112 for accommodating the internal antenna unit 32 is provided on the inner wall of the face shell 11. In this embodiment, the internal antenna unit 32 can be accommodated and limited by the strip-shaped groove 112, making the internal structure of the housing 1 more compact and improving stability. Specifically, the internal antenna unit 32 is of a ring structure, and the cross-section of the strip-shaped groove 112 is semi-circular.

[0032] Further, a speaker 14 is provided in the bottom shell 12. An ear tip 16 communicating with the speaker 14 is sleeved on one end of the bottom shell 12 away from the face shell 11. In this embodiment, the ear tip 16 is used to extend into the ear canal, and the speaker 14 is used to appropriately amplify the sound collected by the microphone 15 and broadcast it into the user's ear canal to achieve a hearing aid effect. Specifically, the deep-ear canal Bluetooth hearing aid includes a plurality of ear tips 16 of different size specifications, and the user can select the ear tip 16 according to their own needs, providing a better user experience.

[0033] Further, a microphone 15 is provided on the main board 13, and a plurality of through holes 113 corresponding to the position of the microphone 15 are formed on the front shell 11. In this embodiment, the microphone 15 is used to collect external sounds, and the microphone 15 is disposed inside the housing 1. The housing 1 can protect the microphone 15 to improve its service life. The through holes 113 are used for sound to pass through the front shell 11, facilitating the microphone 15 to receive external sounds.

[0034] Further, the abutting surfaces of the abutting block 21 and the abutting groove 111 are both set as arc-shaped surfaces. In this embodiment, the arc-shaped surface has a larger contact area compared to the flat surface, so that the pressure can be distributed more evenly, reducing local stress concentration and enhancing the stability and load-bearing capacity between the abutting block 21 and the abutting groove 111; the arc-shaped surface contact can also reduce friction and wear, and extend the service life of the abutting block 21 and the abutting groove 111.

[0035] Further, a spherical holding structure 22 is provided at the end of the holding member 2. In this embodiment, by providing the spherical holding structure 22, the holding member 2 can be more easily grasped and moved, avoiding the problem of the user's hand slipping when pulling the holding member 2.

[0036] The above are only the optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
