[0027] Now, the present utility model will be further described in combination with the accompanying drawings and specific implementation manners.

[0028] Refer to Figures 1 to 7 As shown, this embodiment provides a glasses-type air-conduction hearing aid with a microphone, including a glasses main body 10 with temple arms 11 and a receiver 20; specifically, in this embodiment, the glasses main body 10 includes a frame 12, lenses 13 provided on the frame 12, and two temple arms 11 hinged on both sides of the frame 12; of course, in other embodiments, the glasses main body 10 can also be a frameless glasses, that is, the two temple arms 11 are directly assembled on the two lenses 13; or it can be glasses without lenses, that is, a structure only including the frame 12 and the temple arms 11, etc.

[0029] Among them, both temple arms 11 of the glasses main body 10 are provided with installation cavities 101 and sound outlet openings 102 provided on the surface of the temple arms 11 and communicating with the installation cavities 101; the number of the receivers 20 is two, and they are respectively assembled in the installation cavities 101 of the two temple arms 11; such a layout not only saves space but also better conforms to the wearing habits of users.

[0030] It further includes two microphones 50, the two microphones 50 are respectively assembled on the two temple arms 11, the microphone 50 has a sound guide channel 51 and a convex portion 52 protruding and extending towards the inner side of the temple arm 11; the sound outlet opening 102 of the temple arm 11 communicates with the sound guide channel 51, and the sound outlet 511 of the sound guide channel 51 is arranged at the end of the convex portion 52.

[0031] After the user wears it, the convex part 52 of the sound collector 50 faces the ear canal position. The structure of the convex part 52 of the sound collector 50 is different from the existing in-ear structure. After wearing, the convex part 52 does not plug into the ear canal; instead, the sound outlet 511 of the sound guiding channel 51 is aligned with the user's ear canal opening. After the sound emitted by the receiver 20 is transmitted out through the sound outlet 102 of the temple 11, it will be concentrated and output to the user's ear canal under the guidance of the sound guiding channel 51 of the sound collector 50, effectively improving the problems of large sound loss and privacy leakage in the transmission of the glasses-type air-conduction hearing aid.

[0032] Specifically, the sound collector 50 is detachably assembled on the temple 11. With this setting, the wearer can choose whether to add the structure of the sound collector 50 according to the actual situation, and it is convenient to replace the sound collector 50.

[0033] More specifically, in this embodiment, the detachable assembly structure of the sound collector 50 is: a sleeve hole 53 is provided on the sound collector 50; the sound collector 50 is sleeved on the temple 11 through the sleeve hole 53; the sleeving assembly method is simpler to operate; of course, in other embodiments, a clamping connection or other methods can also be used for fixation.

[0034] At the same time, in order to ensure the precise assembly of the sound collector 50, the temple 11 includes a front leg portion 111 connecting the frame 12 of the glasses main body 10 and an earrest portion 112 connected to the rear end of the front leg portion 111 for wearing; the rear end of the front leg portion 111 has a rear end face 113 that is lower than the earrest portion 112 and slopes downward, and the sound outlet 102 is provided on the rear end face 113; a contact surface 54 that abuts and cooperates with the rear end face 113 of the front leg portion 111 is provided on the sound collector 50. During assembly, the sound collector 50 is inserted from the end of the temple 11 (i.e., the earrest portion 112) until the contact surface 54 abuts against the rear end face 113 of the front leg portion 111 to achieve precise assembly; it can align the sound inlet of the sound guiding channel 51 of the sound collector 50 with the sound outlet 102 on the temple 11 to ensure effective sound collection.

[0035] The sound outlet 102 is provided on the rear end face 113. The sound guiding channel 51 of the sound collector 50 is in an "L" shape, that is, the first half 501 connecting the sound outlet 102 and the second half 502 forming the sound outlet 511 of the sound guiding channel 51 form a certain angle, forming a curved channel. The sound outlet 511 of the sound collector 50 directly points to the user's ear canal opening in a twisted manner, and the sound can be effectively transmitted to the ear canal, thereby providing a better auditory experience.

[0036] Specifically, the material of the sound collector 50 is silica gel, which can transmit sound more effectively. Of course, in other embodiments, the material of the sound collector 50 can also be other soft or hard rubber materials such as rubber that can effectively transmit sound.

[0037] The sound output part of the receiver 20 is connected to the sound outlet 102 of the temple 11 through a rubber hose 30, so that the sound wave output by the receiver 20 is transmitted from the sound outlet 102 of the temple 11 after being conducted through the rubber hose 30. Similar to the above-mentioned microphone 50, when the sound passes through the rubber hose 30, the high-frequency sound is appropriately amplified, thus significantly improving the speech clarity of hearing-impaired patients. In this way, the sound emitted by the receiver 20 can be more effectively directionally transmitted throughout the process.

[0038] At the same time, due to the setting of the rubber hose 30 and the way the sound outlet 102 is arranged on the rear end surface 113 of the front leg part 111, when the user removes the microphone 50 for wearing, the sound outlet 102 can well correspond to the position of the concha. After the sound is conducted through the rubber hose 30, it can be well focused and transmitted to the position of the concha, ensuring that the sound can be accurately and directly transmitted into the user's ear canal. Even without the structure of the microphone 50, the conduction of sound can be well achieved. Of course, with the added microphone 50 in this embodiment, the sound can be directly concentrated and output to the user's ear canal, and the effect will be better.

[0039] The inner wall of the installation cavity 101 of the temple 11 is also provided with a fixing groove 103 communicating with the sound outlet 102, and the rubber hose 30 is inserted into the fixing groove 103; the rubber hose 20 can be well positioned and assembled on the temple 11. At the same time, for better fixing, in this embodiment, the rubber hose 30 and the temple 11 are fixed by glue, which further ensures that the electroacoustic signal can be stably and efficiently converted into sound.

[0040] A connecting cylinder 40 is also assembled on the sound output part of the receiver 20, and the connecting cylinder 40 is fixedly inserted into the rubber hose 30; in this way, the assembly of the receiver 20 and the rubber hose 30 is realized; the structure is simple and the assembly operation is easy.

[0041] Of course, in other embodiments, the fixed installation structures of the receiver 20, the rubber hose 30 and the temple 11 are not limited to this, and other methods such as snap connection or direct glue bonding can also be used.

[0042] At the same time, in order to more conveniently hide and assemble the receiver 20 in the installation cavity 101 of the temple 11; the temple 11 at least includes a first part and a second part that can be detachably separated, and the first part and the second part are assembled and spliced together to jointly form the installation cavity 101; when it is necessary to install and disassemble the internal receiver 20, the first part and the second part can be separated first. After the assembly of the receiver 20 is completed, the first part and the second part are re-spliced to form a complete temple 11 structure.

[0043] Further, in this embodiment, the receiver 20 may be a single bandwidth receiver unit, or a combination of multiple receiver units with different bandwidths, and so on.

[0044] Although the present utility model has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present utility model in terms of form and details without departing from the spirit and scope of the present utility model defined by the appended claims, and all of them fall within the protection scope of the present utility model.
