Description

Technical Field

[0001] This utility model relates to the field of hearing testing and hearing impairment diagnosis technology, and in particular to an air conduction earphone. Background Technology

[0002] The pure-tone audiometry air conduction headset is a device specifically designed for hearing testing and hearing impairment diagnosis. Utilizing the principle of air conduction, it transmits pure-tone signals of different frequencies and intensities to the subject through the headset, thereby accurately measuring their hearing threshold. In clinical applications, doctors can accurately determine the degree and nature of hearing loss by comparing the hearing thresholds of the healthy and affected ears, providing strong support for the early detection, diagnosis, and treatment of hearing impairment.

[0003] Currently available pure-tone hearing threshold testing air conduction headphones have revealed several shortcomings in practical use. One issue is that these headphones require a complete seal around the test subject's ear; however, the earcups cannot be adjusted to fit the shape of the test subject's ear or face. This prevents them from achieving the necessary seal in practice, severely impacting test accuracy and reducing efficiency. Test subjects may need to repeatedly adjust the headphone position or even repeat the test, increasing time costs and potentially leading to inaccurate and inconsistent results, thus affecting the accurate assessment of hearing loss. Utility Model Content

[0004] To address the technical problem of poor testing accuracy in existing pure-tone hearing threshold testing air-conduction headphones, an air-conduction headphone is provided that allows adjustment of both ear tip components and the depth of the earplug insertion into the ear canal to improve testing accuracy.

[0005] An air-conduction earphone, comprising:

[0006] Headband assembly;

[0007] Two drive structures are respectively disposed at both ends of the headband assembly;

[0008] Two earplugs, each corresponding to one of the two drive structures, are mounted on the headband assembly via the corresponding drive structure, and the drive structure can move the corresponding earplug relative to the headband assembly to adjust the depth of insertion into the ear canal.

[0009] The earplugs are provided with vent holes, and the vent holes of both earplugs are connected to a preset instrument through gas pipelines.

[0010] The drive structure includes a mounting body and a slider. The mounting body is disposed on the headband assembly, and the slider is movably disposed on the mounting body and is movable relative to the mounting body. The earpiece is connected to the slider.

[0011] The drive structure also includes a knob, which is rotatably mounted on the mounting body, and the slider is driven by the knob, so that the knob can rotate to move the slider.

[0012] The slider is provided with a threaded hole, and the knob is provided with an external thread. The external thread and the threaded hole are threaded together to realize the movement of the slider.

[0013] The first end of the mounting body is disposed on the headband assembly, and the second end of the mounting body is disposed on the corresponding earplug. The mounting body can deform to drive the earplug to perform curved movement.

[0014] The driving structure is movably disposed on the headband assembly, and the direction of movement of the driving structure is different from the direction of movement of the earpiece.

[0015] The headband assembly is provided with at least one first adjusting member, and the drive structure is provided with at least two second adjusting members, wherein any one of the first adjusting members can engage with any one of the second adjusting members.

[0016] The air-conducting earphone further includes a first tube and a second tube, and the two earplugs include a first earplug and a second earplug. The vent of the first earplug is connected to the preset instrument through the first tube, and the vent of the second earplug is connected to the preset instrument through the second tube.

[0017] The air-conducting earphone also includes a connecting tube, and the two earplugs include a first earplug and a second earplug. One end of the connecting tube is connected to the preset instrument, and the other end of the connecting tube is connected to the vent hole of the first earplug and the vent hole of the second earplug, respectively.

[0018] The earpiece is hinged to the corresponding drive structure.

[0019] The air-conducting headphones also include a handle, which corresponds to one of the earpieces. The earpieces are mounted on the corresponding handles, and the handles are hinged to the drive structure.

[0020] The inner wall of the headband assembly near the earplug has a protrusion structure that can abut against and fit with the tester's head.

[0021] The air-conduction earphone provided by this utility model uses a driving structure to move the earplug, so that the earplug can be adjusted in position within the ear canal to fit the tester's ear canal, thereby ensuring the sealing effect of the earplug on the ear canal. This overcomes the problem of existing technologies that rely solely on the earmuff covering the tester's ear without being able to reliably seal the ear, effectively improving the accuracy of the test. It also avoids repeated testing, thus improving work efficiency and increasing the accuracy of testing the degree of hearing loss of the tester. Attached Figure Description

[0034] Currently available pure-tone hearing threshold testing air conduction headphones have revealed several shortcomings in practical use. One issue is that these headphones require a complete seal around the test subject's ear; however, the earcups cannot be adjusted to fit the shape of the test subject's ear or face. This prevents them from achieving the necessary seal in practice, severely impacting test accuracy and reducing efficiency. Test subjects may need to repeatedly adjust the headphone position or even repeat the test, increasing time costs and potentially leading to inaccurate and inconsistent results, thus affecting the accurate assessment of hearing loss.

[0035] Therefore, this application provides a method such as Figures 1 to 5 The air-conduction earphone shown includes a headband assembly 1; two drive structures 2, each disposed at one end of the headband assembly 1; and two earplugs 3, each corresponding to one of the drive structures 2. The earplugs 3 are mounted on the headband assembly 1 via their respective drive structures 2, and each drive structure 2 can move the corresponding earplug relative to the headband assembly 1 to adjust its depth into the ear canal. Each earplug 3 has a vent 31, and both vent 31 are connected to a preset instrument via gas tubing. By using the drive structures 2 to move the earplugs 3, the earplugs 3 can be adjusted in position within the ear canal to fit the tester's ear canal, ensuring a proper seal. This overcomes the problem in existing technologies where simply covering the ear with an earmuff does not provide a reliable seal, effectively improving testing accuracy. It also avoids repeated testing, increasing work efficiency and improving the accuracy of testing the degree of hearing loss.

[0036] During use, the tester or operator holds one earplug 3 in each hand and increases the distance between the two earplugs 3. When the distance between the two earplugs 3 exceeds the distance between the tester's ears, the air-conducting headphones are put on the head. At this time, the headband assembly 1 will deform due to the increased distance between the two earplugs 3. After the air-conducting headphones are put on the head, the headband assembly 1 will return to its original shape, thus clamping the two earplugs 3 onto the tester's head. At the same time, the earplugs 3 will extend into the corresponding ear canal of the tester. Since the ear canal shape of different testers is different, the position of the earplugs 3 is adjusted by the drive structure 2 so that the earplugs 3 can extend into the corresponding size part of the ear canal, thereby ensuring that the earplugs 3 completely seal the ear canal. Then, the air vent 31 of the earplugs 3 can be supplied with test gas for testing. This overcomes the problem of existing technologies that only have earmuffs but cannot seal the ear canal, effectively improving the test accuracy and the precision of testing the degree of hearing loss of the tester.

[0037] In one embodiment, the driving structure 2 includes a mounting body 21 and a slider 22. The mounting body 21 is disposed on the headband assembly 1, and the slider 22 is movably disposed on the mounting body 21 and is movable relative to the mounting body 21. The earplug 3 is connected to the slider 22. The movement of the slider 22 enables the movement of the earplug 3 relative to the headband assembly 1. When the headband assembly 1 is worn on the head, the position of the earplug 3 within the ear canal can be adjusted. This ensures that when the headband assembly 1 is properly fitted to the head, the earplug 3 can reliably seal the ear canal while preventing the earplug 3 from being inserted too deeply and causing injury to the test subject.

[0038] Specifically, the drive structure 2 also includes a knob 23, which is rotatably mounted on the mounting body 21. The slider 22 is in a transmission engagement with the knob 23, and the knob 23 can rotate to move the slider 22. The rotation of the knob 23 drives the slider 22. The knob 23 is exposed on the outer surface of the air-conducting earphone, facilitating the user's operation of the earplug 3. The rotation of the knob 23 also reduces the movement speed of the slider 22, preventing excessive speed movement and potential ear canal damage, thus improving user comfort.

[0039] Optionally, the slider 22 is provided with a threaded hole, and the knob 23 is provided with an external thread. The external thread engages with the threaded hole to realize the movement of the slider 22. The threaded engagement enables the rotation of the knob 23 to be transmitted linearly to the slider 22, thereby ensuring that the earplug 3 also moves linearly, achieving reliable adjustment within the ear canal.

[0040] The first end of the mounting body 21 is disposed on the headband assembly 1, and the second end of the mounting body 21 is disposed on the corresponding earplug 3. The mounting body 21 can deform to drive the earplug 3 to perform curved movement. The deformation of the mounting body 21 further adjusts the position of the earplug 3 and the angle of insertion into the ear canal, and also further adapts the air-conducting headphones to the shape of the tester's head, improving the tester's wearing comfort. Figure 1 or Figure 4 As shown, the mounting body 21 is L-shaped. When the two earplugs 3 are subjected to external force, the included angle of the L-shape can change, thereby causing the mounting body 21 to deform. The mounting body 21 is made of rigid material. When the air conduction headphones are worn on the tester's head, the mounting body 21 can recover part of the deformation. The deformation that cannot be recovered can increase the clamping effect on the tester's head, improve the wearing reliability of the air conduction headphones, and further enhance the force of the earplugs 3 into the ear canal, thereby improving the sealing effect of the earplugs 3 on the ear canal.

[0041] Furthermore, the driving structure 2 is movably mounted on the headband assembly 1, and the direction of movement of the driving structure 2 is different from the direction of movement of the earpiece 3. By utilizing the movement of the driving structure 2 relative to the headband assembly 1, further adjustment of the earpiece 3 in directions other than its own movement is achieved, increasing the degree of freedom of the earpiece 3 and further improving the adaptability of the air-conducting headphones to different head shapes of testers, thereby improving testing accuracy and tester comfort.

[0042] Specifically, the headband assembly 1 is provided with at least one first adjusting member 41, and the drive structure 2 is provided with at least two second adjusting members 42, wherein any one of the first adjusting members 41 can engage with any one of the second adjusting members 42. By utilizing the different engagements between the first adjusting members 41 and the second adjusting members 42, the drive structure 2 and the headband assembly 1 can be fixed at different positions, further enabling position adjustment between the two earpieces 3 and improving the fit of the air-conducting headphones to the tester's head shape.

[0043] Optionally, multiple second adjusting members 42 are provided on the drive structure 2, and all the second adjusting members 42 are arranged sequentially along the sliding direction of the drive structure 2. A first adjusting member 41 is provided on the headband assembly 1, and the first adjusting member 41 can cooperate with any of the second adjusting members 42. For example, the drive structure 2 is provided with multiple grooves, and the headband assembly 1 is provided with a protrusion. The protrusion can engage with any of the grooves. When adjustment is required, the protrusion can slide out of the groove under the action of external force and continue to slide into another groove, thereby realizing the engagement between the drive structure 2 and the headband assembly 1 again.

[0044] Optionally, the first adjusting member 41 and the second adjusting member 42 can also be locked together by means of threaded connection or spring connection.

[0045] The air-conducting earphone also includes a first tube 51 and a second tube 52. The two earplugs 3 include a first earplug 32 and a second earplug 33. The vent 31 of the first earplug 32 is connected to the preset instrument through the first tube 51, and the vent 31 of the second earplug 33 is connected to the preset instrument through the second tube 52. Air is supplied to the vent 31 of the first earplug 32 through the first tube 51, and to the vent 31 of the second earplug 33 through the second tube 52. The preset instrument can provide the corresponding gas according to the testing requirements to achieve separate testing of both ears, further reducing the operational complexity of the test. When the tester only needs to test one ear, the other earplug 3 can also increase the sealing effect of the earplug 3 on the side to be tested by fixing it in the ear canal, improving the accuracy of the test and the precision of the hearing loss degree.

[0046] Alternatively, the air-conducting earphone may further include a connecting tube. The two earplugs 3 include a first earplug 32 and a second earplug 33. One end of the connecting tube is connected to the preset instrument, and the other end is connected to the vent 31 of the first earplug 32 and the second earplug 33, respectively. In this case, the air-conducting earphone is connected to the preset instrument through a connecting tube. The connecting tube then uses its own structure or related structures to divert the airflow, thereby ensuring that the vent 31 of both earplugs 3 are connected to the preset instrument. This further reduces the structural complexity of the air-conducting earphone and improves its structural reliability.

[0047] The earplug 3 is hinged to the corresponding drive structure 2. The hinged connection between the earplug 3 and the drive structure 2 further enables position adjustment of the earplug 3, improving the ability to adjust the position of the earplug 3 and the angle at which it is inserted into the ear canal. This allows the earplug 3 to maintain a comfortable angle with the ear canal, enhancing the user experience and further adapting the air-conducting headphones to the shape of the user's head, thus improving wearing comfort.

[0048] Optionally, the cross-section of the earplug 3 can be circular or elliptical, allowing the earplug 23 to better adapt to the shape of the ear canal and improve the seal on the tester's ear. The shape of the earplug 3 can be conical, cylindrical, or frustum-shaped, etc.

[0049] The air-conducting earphone also includes a handle 34, which corresponds one-to-one with each earplug 3. Each earplug 3 is mounted on its corresponding handle 34, and the handle 34 is hinged to the drive structure 2. By designing the handle 34, whose size is significantly larger than the earplug 3, it facilitates easy handling by the tester or operator. During use, the tester or operator simply holds the handle 34 corresponding to each earplug 3 with both hands. Simultaneously, the drive structure 2, through its hinged connection with the handle 34, facilitates both the connection between the drive structure 2 and the earplug 3 and the adjustment of the earplug 3's angle, allowing it to be inserted into the ear canal at a more comfortable angle. The handle 34 and the slider 22 are hinged together via a rotating pin.

[0050] The headband component 1 includes an arc-shaped strip, the shape of which can fit most testers' head shapes, thus making it convenient for testers to wear.

[0051] Optionally, the inner wall of the headband assembly near the earplug is provided with a protrusion structure 11, which can abut and cooperate with the tester's head. The protrusion structure 11 forms an inward protrusion at the position of the headband assembly near the earplug 3, ensuring reliable contact between the headband assembly and the tester's head, ensuring the air-conducting headphones are reliably worn on the tester's head. Simultaneously, the protrusion structure 11 also supports the earplug 3, thereby ensuring a proper fit between the earplug 3 and the ear canal, improving the tester's comfort.

[0052] The specific operation for using the air-conduction headphones described in this application is as follows:

[0053] I. Procedures before putting on the air conduction headphones:

[0054] Pick up both earbuds 3 with both hands at the same time, gently pry them apart to a position wider than your head, raise the air conduction headphones above your head, and when the two earbuds 3 are roughly aligned with the corresponding ear canal positions, gently release the two earbuds 3 so that the two earbuds 3 are initially inserted into the ear canal, and then remove your hands from the headphones.

[0055] Rotate knob 23 with both hands to fine-tune the insertion of earplug 3 into the ear canal, adjusting the spacing and force to achieve the appropriate fit. This makes the tester more comfortable, improves overall sealing, and increases the success rate.

[0056] II. Procedure for removing the air-conduction headphones:

[0057] Pick up both earbuds 3 with both hands at the same time, gently pry them apart to a position wider than your head, raise the air conduction headphones above your head, and gently bring the two earbuds 3 together to return to their natural state.

[0058] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
