Description

Technical Field

[0001] The present application belongs to the field of earphone technology, and more specifically, relates to an earphone body and an open earphone. Background Art

[0002] Since open-back headphones do not enter the ear and do not directly stimulate the eardrum, they greatly reduce damage to the ear and are therefore very popular among consumers.

[0003] When using open-back headphones, users can receive external sounds and sounds emitted by the headphones at the same time. In order to reduce noise, some open-back headphones are designed with noise reduction functions. The noise reduction function is generally divided into passive noise reduction and active noise reduction. The active noise reduction function is achieved by setting a feedback microphone in the earphone shell of the open-back headphones. The feedback microphone picks up the sound in the user's ear canal through the pickup port on the earphone shell, and then analyzes and processes it through the built-in circuit board to generate sound waves with an opposite phase to the noise, thereby offsetting the ambient noise.

[0004] At present, the sound pickup port and the outer surface of the earphone shell are on the same plane or curved surface, but the shape and size of each person's ears are different. When some users wear them, the sound pickup port will contact the ear skin, causing the sound pickup port to be blocked and howling to occur, giving the user a bad experience. Utility Model Content

[0030] Please also read Figures 1 to 3 , an earphone body 100 is now described in an embodiment of the present application.

[0031] Please also read Figure 1 and Figure 2 The earphone body 100 includes an earphone shell 10 and a feedback microphone 20. The earphone shell 10 is provided with a accommodating cavity 11. The earphone shell 10 is formed with a surface wall 12. The surface wall 12 has an outer surface 121 that is away from the accommodating cavity 11. The surface wall 12 is provided with a through opening 123 and a plurality of sound pickup ports 122. The through opening 123 is connected with the accommodating cavity 11. The plurality of sound pickup ports 122 all penetrate the outer surface 121. On the outer surface 121, the plurality of sound pickup ports 122 are distributed at intervals, and each sound pickup port 122 is connected with the through opening 123. The feedback microphone 20 is arranged in the accommodating cavity 11 and is arranged corresponding to the through opening 123.

[0032] Among them, the facing wall 12 refers to the part of the earphone shell 10 close to the user's ear canal and covering the entrance of the ear canal when the user wears the earphone body 100 on the user's ear. It can be understood that when the user wears the earphone body 100 on the ear, the earphone shell 10 fits the user's ear, the facing wall 12 covers the entrance of the user's ear canal, and the outer surface 121 faces the entrance of the ear canal.

[0033] The corresponding arrangement of the feedback microphone 20 and the opening 123 means that the feedback microphone 20 corresponds to and covers the opening 123 . It can be understood that when worn, the sound in the ear canal can be transmitted from the sound pickup port 122 to the opening 123 to be picked up by the feedback microphone 20 .

[0034] Compared with the prior art, the earphone body 100 provided in the present application has the earphone shell 10 fitted to the user's ear when worn, and the outer surface 121 of the face wall 12 faces and covers the entrance of the user's ear canal. The feedback microphone 20 picks up the sound in the user's ear canal through the through opening 123 and the sound pickup opening 122. By opening a plurality of sound pickup openings 122 in the face wall 12, and distributing the plurality of sound pickup openings 122 at intervals on the outer surface 121, the earphone body 100 can be effectively prevented from blocking all the sound pickup openings 122 at the same time when worn. It can be understood that even if part of the sound pickup openings 122 are blocked, another part of the sound pickup openings 122 are exposed and connected to the ear canal, so that the feedback microphone 20 can normally pick up the sound in the user's ear canal, thereby effectively avoiding the generation of howling, which is beneficial to improving the user's usage experience.

[0035] In one embodiment of the present application, the spacing between the multiple sound pickup ports 122 is greater than 1 mm.

[0036] Optionally, the spacing between the multiple sound pickup ports 122 may be 1.2 mm, 1.5 mm, 1.8 mm, etc.

[0037] By setting the spacing between the multiple sound pickup ports 122 to be greater than 1 mm, the spacing is relatively large, which effectively prevents all the sound pickup ports 122 from being blocked by the user's ear skin at the same time when worn, so that at least part of the sound pickup ports 122 are exposed and connected to the user's ear canal entrance.

[0038] In one embodiment of the present application, see Figure 2 The surface wall 12 is dome-shaped, and the outer surface 121 is a convex arc surface. On the outer surface 121, multiple sound pickup ports 122 are distributed in sequence along the length direction of the earphone shell 10.

[0039] Specifically, along the length direction of the earphone shell 10 , the distance between two adjacent sound pickup ports 122 is greater than 1 mm.

[0040] When the outer surface 121 is a convex arc surface, the multiple sound pickup ports 122 are distributed in sequence along the length direction of the earphone shell 10. In this way, the multiple sound pickup ports 122 are not on the same plane, thereby effectively preventing the ear skin from blocking all the sound pickup ports 122 when wearing.

[0041] In one embodiment of the present application, the surface wall 12 is dome-shaped, and the feedback microphone 20 is disposed near the center of the surface wall 12 .

[0042] Specifically, see Figure 3 The earphone shell 10 includes a first shell 14 and a second shell 15. The first shell 14 and the second shell 15 are connected to form a receiving cavity 11. The surface wall 12 is part of the first shell 14 and protrudes in a dome shape in a direction away from the second shell 15.

[0043] In another embodiment of the present application, the feedback microphone 20 is disposed at the center of the face wall 12 .

[0044] Since the face wall 12 is dome-shaped, the space between the center of the face wall 12 and the speaker 30 is relatively large. By arranging the feedback microphone 20 at the center of the face wall 12 or near the center of the face wall 12, the thickness of the earphone shell 10 does not need to be increased or the increased thickness is relatively small, thereby facilitating the miniaturization of the earphone body 100.

[0045] In one embodiment of the present application, see Figure 2 The face wall 12 is provided with a plurality of sound pickup channels 124 , one end of the plurality of sound pickup channels 124 penetrates the outer surface 121 to form a plurality of sound pickup openings 122 , and the other ends of the plurality of sound pickup channels 124 are joined and connected to form a through opening 123 .

[0046] Optionally, there are two sound pickup channels 124, and the two sound pickup channels 124 roughly form an L shape, so that the two sound pickup ports 122 are not on the same plane, effectively preventing the two sound pickup ports 122 from being blocked by the skin of the user's ears at the same time when worn.

[0047] Of course, there may be three sound pickup channels 124, and the three sound pickup channels 124 may roughly form a T shape. Figure 2 , so that the three sound pickup ports 122 are not on the same plane, effectively preventing the three sound pickup ports 122 from being blocked by the skin of the user's ear at the same time when worn.

[0048] In one embodiment of the present application, see Figure 2 The surface wall 12 further has an inner surface 125 facing the accommodating cavity 11 . The inner surface 125 is formed with a protrusion 126 , and the sound pickup channel 124 passes through the protrusion 126 .

[0049] Specifically, the inner surface 125 is disposed opposite to the outer surface 121 .

[0050] Optionally, the protrusion 126 and the surface wall 12 are integrally formed, so that the structure is stable, the process is simple, and the production cost is low.

[0051] By forming a protrusion 126 on the inner surface 125, the sound pickup channel 124 passes through the protrusion 126, which effectively ensures the strength of the portion of the face wall 12 where the sound pickup channel 124 is provided, and effectively avoids the portion of the face wall 12 where the sound pickup channel 124 is provided being too weak and easily damaged. At the same time, the protrusion 126 is formed on the inner surface 125, and there is no need to increase the overall thickness of the earphone shell 10, which is beneficial to reducing the weight of the earphone body 100 and making it easier for users to use and carry.

[0052] Please also refer to Figure 2 and Figure 3 The raised portion 126 is provided with a limiting ring 127 , the limiting ring 127 is provided corresponding to the sound pickup port 122 , and the feedback microphone 20 is limited in the limiting ring 127 .

[0053] Specifically, the limiting ring 127 and the surface wall 12 are integrally formed, which has a simple process and low production cost.

[0054] Optionally, the shape of the limiting ring 127 matches the shape of the feedback microphone 20, and the feedback microphone 20 is clamped in the limiting ring 127. In addition, the feedback microphone 20 can be limited in the limiting ring 127 by bonding, magnetic attraction, etc.

[0055] By setting a limiting ring 127 corresponding to the sound pickup port 122 on the raised portion 126 and limiting the feedback microphone 20 within the limiting ring 127, when worn, the distance between the feedback microphone 20 and the user's eardrum is shorter, so that the sound picked up by the feedback microphone 20 is closer to the sound at the eardrum, which is beneficial to improving the noise reduction effect.

[0056] In one embodiment of the present application, see Figure 2 The earphone body 100 also includes a speaker 30 and a circuit board 40. The speaker 30 and the circuit board 40 are both arranged in the accommodating cavity 11. The surface wall 12 is also provided with a sound outlet 13, which is connected to the accommodating cavity 11. The speaker 30 and the feedback microphone 20 are both electrically connected to the circuit board 40.

[0057] When worn, the sound outlet 13 is directly opposite to the entrance of the user's ear canal, and the sound output by the speaker 30 is transmitted to the user's ear canal through the sound outlet 13. When active noise reduction is performed, the feedback microphone 20 picks up the sound in the user's ear canal through the opening 123 and the sound pickup port 122. The feedback microphone 20 feeds back the picked-up ambient noise and target sound to the circuit board 40. After analyzing and processing the ambient noise, the circuit board 40 generates a sound wave with a phase opposite to the ambient noise to offset the ambient noise, thereby eliminating noise interference near the ear canal, allowing the target sound output by the speaker 30 to be transmitted to the user's ear canal more purely, which is beneficial to improving the clarity of the sound quality.

[0058] See also Figure 1 The present application also provides an open-type earphone, comprising an ear hook 200 and an earphone body 100 as described in any of the above embodiments, wherein the ear hook 200 is curved, and one end of the ear hook 200 is connected to the earphone shell 10. When worn, the ear hook 200 is hung on the ear of the user. It can be understood that the open-type earphone is an ear hook earphone.

[0059] Compared with the prior art, the open earphones provided by the present application adopt the above-mentioned earphone body 100. When worn, the earphone shell 10 fits the user's ear, and the outer surface 121 of the face wall 12 faces and covers the entrance of the user's ear canal. The feedback microphone 20 picks up the sound in the user's ear canal through the through opening 123 and the sound pickup opening 122. By opening a plurality of sound pickup openings 122 in the face wall 12, and distributing the plurality of sound pickup openings 122 at intervals on the outer surface 121, the skin of the ear can be effectively prevented from blocking all the sound pickup openings 122 at the same time when worn. It can be understood that even if part of the sound pickup openings 122 are blocked, another part of the sound pickup openings 122 are exposed and connected to the ear canal, so that the feedback microphone 20 can normally pick up the sound in the user's ear canal, thereby effectively avoiding the generation of howling, which is beneficial to improving the user's usage experience.

[0060] Optionally, the open-type earphone is a Bluetooth wireless earphone, and the open-type earphone also includes a battery, which is arranged in the shell or in the ear hook 200, and the battery is used to provide electrical energy.

[0061] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
