[0025] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0026] In the description of the present invention, terms such as "up", "down", "left", "right", "front", "back", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0027] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0028] Reference Figures 1 to 7 As shown, this embodiment provides a glasses-type air conduction hearing aid with a sound collector, including a glasses body 10 with temples 11 and a receiver 20; specifically, in this embodiment, the glasses body 10 includes a frame 12, a lens 13 arranged on the frame 12, and two temples 11 hinged on both sides of the frame 12; of course, in other embodiments, the glasses body 10 can also be frameless glasses, that is, the two temples 11 are directly assembled on the two lenses 13; or lensless glasses, that is, only the structure of the frame 12 and the temples 11, etc.

[0029] Among them, the two temples 11 of the eyeglass body 10 are both provided with an installation cavity 101 and a sound outlet 102 arranged on the surface of the temple 11 and connected to the installation cavity 101; the number of the receivers 20 is two, and they are respectively assembled in the installation cavities 101 of the two temples 11; such a layout not only saves space, but also better fits the user's wearing habits.

[0030] It also includes two sound collectors 50, which are respectively assembled on two temples 11, and the sound collectors 50 have a sound guide channel 51 and a protrusion 52 protruding and extending toward the inner side of the temple 11; the sound outlet 102 of the temple 11 is connected to the sound guide channel 51, and the sound outlet 511 of the sound guide channel 51 is arranged at the end of the protrusion 52.

[0031] After the user wears the earphone, the raised portion 52 of the sound collector 50 faces the ear canal. The structure of the raised portion 52 of the sound collector 50 is different from the existing in-ear structure. After wearing, the raised portion 52 is not inserted into the ear canal; instead, the sound outlet 511 of the sound guide channel 51 is aligned with the ear canal opening of the user. After the sound emitted by the receiver 20 is transmitted through the sound outlet 102 of the temple 11, it will be concentratedly output to the ear canal of the user under the guidance of the sound guide channel 51 of the sound collector 50, effectively improving the problem of large sound loss and privacy leakage of the eyeglass-type air conduction hearing aid.

[0032] Specifically, the sound collector 50 is detachably mounted on the temple 11 . With this arrangement, the wearer can choose whether to add the structure of the sound collector 50 according to actual conditions, and the sound collector 50 can be easily replaced.

[0033] More specifically, in the present embodiment, the detachable assembly structure of the sound collector 50 is as follows: 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 sleeve assembly method is adopted, and the operation is simpler; of course, in other embodiments, the sound collector 50 can also be fixed by means of snap-on connection or the like.

[0034] At the same time, in order to ensure the accurate assembly of the sound collector 50, the temple 11 includes a front leg portion 111 connected to the frame 12 of the eyeglass body 10 and an ear rest 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 surface 113 that is lower than the ear rest portion 112 and tilted downward, and the sound outlet 102 is arranged on the rear end surface 113; the sound collector 50 is provided with a contact surface 54 that contacts and cooperates with the rear end surface 113 of the front leg portion 111. During assembly, the sound collector 50 is inserted from the end of the temple 11 (i.e., the ear rest portion 112) until the contact surface 54 contacts the rear end surface 113 of the front leg portion 111, so as to achieve accurate assembly; the sound inlet of the sound guide channel 51 of the sound collector 50 can be aligned with the sound outlet 102 on the temple 11, so as to ensure that the sound can be effectively collected.

[0035] The sound outlet 102 is arranged on the rear end surface 113, and the sound guide channel 51 of the sound collector 50 is "L"-shaped, that is, the sound guide channel 51 connects the front half 501 of the sound outlet 102 and the rear half 502 forming the sound outlet 511 at a certain angle to form a curved channel. The sound outlet 511 of the sound collector 50 is directly pointed to the ear canal opening of the user in a twisted manner, and the sound can be effectively transmitted to the ear canal, thereby providing a better auditory experience.

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

[0037] The sound outlet of the receiver 20 is connected to the sound outlet 102 of the temple 11 through a rubber hose 30, so that the sound waves output by the receiver 20 are transmitted through the rubber hose 30 and then transmitted from the sound outlet 102 of the temple 11. As with the above-mentioned sound collector 50, when the sound passes through the rubber hose 30, the high-frequency sound is appropriately amplified, thereby significantly improving the speech clarity of the hearing-impaired patient. In this way, the sound emitted by the receiver 20 can be more effectively transmitted in a directional manner throughout the entire process.

[0038] At the same time, the arrangement of the rubber hose 30 and the arrangement of the sound outlet 102 on the rear end surface 113 of the front leg 111, when the user removes the sound collector 50 to wear it, the sound outlet 102 can well correspond to the position of the concha cavity, and the sound can be well focused and transmitted to the position of the concha cavity after being conducted by the rubber hose 30, ensuring that the sound can be accurately and directly transmitted to the user's ear canal. Even without the structure of the sound collector 50, the sound conduction can be well achieved. Of course, the sound collector 50 added in this embodiment can directly output the sound to the user's ear canal, which will have a better effect.

[0039] The inner wall of the mounting inner cavity 101 of the temple 11 is also provided with a fixing groove 103 connected to 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, in order to better fix, in this embodiment, the rubber hose 30 and the temple 11 are fixed by adhesive, which further ensures that the electroacoustic signal can be stably and efficiently converted into sound.

[0040] The sound output portion of the receiver 20 is also equipped with a connecting tube 40, and the connecting tube 40 is fixedly inserted into the rubber hose 30; thus, the receiver 20 and the rubber hose 30 are assembled; the structure is simple and the assembly operation is easy.

[0041] Of course, in other embodiments, the fixed installation structure of the receiver 20, the rubber hose 30 and the temple 11 is not limited thereto, and other methods such as snap-fitting or direct gluing may also be used.

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

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

[0044] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
