Description

Technical Field

[0001] This application relates to the field of loudspeaker technology, and specifically to a rear-mounted composite conductive headphone. Background Technology

[0002] Most headphones on the market currently use both air conduction and / or bone conduction as sound transmission modes. In existing composite headphones that combine bone and air conduction, the bone conduction and air conduction structures are set up separately. That is, the sound-emitting part of the air conduction structure is connected to the ear canal, while the sound-emitting part of the bone conduction structure is located outside the ear contour, attached to the temporal bone. Although the separate bone and air conduction structures can achieve a better sound transmission position and improve the sound transmission effect of the headphones, they increase the size and weight of the headphones. After wearing them for a long time, the area affected by the headphones is larger than that of headphones with only bone or air conduction structures. Moreover, due to the greater weight, the wearing comfort is low, resulting in a poor wearing experience for the user. Utility Model Content

[0003] This application provides a rear-mounted composite conductive headphone, which aims to solve the problem of poor wearing experience in existing headphones.

[0004] In one embodiment, a rear-mounted composite conductive headphone is provided, comprising:

[0005] The outer shell has a first side and a second side for fitting against a human ear; the first side has an opening for communicating with the ear canal of the human ear; the opening is sealed with a vibrating diaphragm.

[0006] A vibration structure, which is fixedly connected to the interior of the outer shell;

[0007] The controller is fixedly connected to the outer casing via a connecting pipe; a transmission line is provided inside the connecting pipe, and the controller is electrically connected to the vibration structure via the transmission line; a mobile power supply electrically connected to the transmission line is provided inside the controller.

[0008] The first and second sides are adjacent sides; the second side fits against the bottom of the concha of the human ear.

[0009] In one embodiment, the number of the controller, the housing, and the vibration structure are all in one-to-one correspondence of two, and the two controllers are fixedly connected together by a connecting line.

[0010] In one embodiment, the vibrating structure abuts against the interior of the outer shell corresponding to the second side.

[0011] In one embodiment, the controller is equipped with a button that is electrically connected to the transmission line.

[0012] In one embodiment, the vibration structure includes: a cylinder and a vibrating element; the outer wall of the cylinder abuts against the inner wall of the outer shell; and the vibrating element is fixedly connected inside the cylinder.

[0013] In one embodiment, the cylinder has a first end and a second end, with a cover plate abutting against the first end; the cover plate abuts against the inner wall of the outer shell corresponding to the second side.

[0014] In one embodiment, a groove is provided on the edge of the opening for the edge of the vibrating diaphragm to engage.

[0015] In one embodiment, the vibrating element includes: a base plate, a coil, a magnet, a vibrating cover, and a connecting piece; the base plate is fixedly connected to the second end, and the base plate is electrically connected and fixed to the coil; the vibrating cover is located inside the cylinder, and the vibrating cover is fixedly connected to the inner wall of the cylinder through the connecting piece; the magnet is adsorbed and fixed to the vibrating cover, and a portion of the magnet extends into the area enclosed by the coil.

[0016] Specifically, the controller has a circuit board, and the buttons are electrically connected to the base plate through the circuit board.

[0017] In one embodiment, a vent hole is provided on the side wall of the cylinder, and the vent hole is close to the opening.

[0018] In one embodiment, demagnetizing sheets are fixedly connected to both the vibrating diaphragm and the magnet.

[0019] The beneficial effects of this application are:

[0020] By placing the vibrating structure inside the shell, the vibration of the vibrating structure is transmitted to the shell when it vibrates. The shell is worn on the ear, with the second side fitting against the ear. The vibration is transmitted to the temporal bone through the ear, achieving a bone conduction effect. The vibrating structure vibrates inside the shell. Since the shell and the vibrating diaphragm form a closed space, the vibration of the vibrating structure causes the air inside the shell to vibrate as well. The breathing effect generated by the air vibration drives the vibrating diaphragm to vibrate as well. The sound of the vibrating diaphragm is transmitted through the ear canal, achieving air conduction.

[0021] This application uses only one sound source. Compared to the separate sound transmission structures of bone conduction and air conduction, which require two sound-generating devices, this application not only reduces the size and weight of the headphones but also lowers production costs. Wearing them is simple; just place the outer shell into the ear. They are easy to wear, and due to their small size and light weight, they have minimal impact on the ears, improving the wearing experience and allowing for extended use. Attached Figure Description

[0034] This application proposes improvements and innovations, and presents the following embodiments.

[0035] In some implementations, please refer to Figures 1 to 3 A rear-mounted composite conductive headphone is provided, comprising:

[0036] The outer shell 1 has a first side 11 and a second side 12 for fitting with the human ear; the first side 11 has an opening 13 for communicating with the ear canal of the human ear; the opening 13 is sealed with a vibrating diaphragm 14.

[0037] Vibration structure 2 is fixedly connected to the inside of the outer shell 1;

[0038] The controller 3 is fixedly connected to the outer casing 1 via a connecting pipe 4; a transmission line is provided inside the connecting pipe 4, and the controller 3 is electrically connected to the vibration structure 2 via the transmission line; a mobile power supply electrically connected to the transmission line is provided inside the controller 3.

[0039] Among them, the first side 11 and the second side 12 are adjacent sides; the second side 12 fits against the bottom of the concha cavity of the human ear. When the second side 12 fits against the concha cavity, the vibration of the second side 12 can be better transmitted to the temporal bone at the bottom of the concha cavity, thus achieving solid sound transmission.

[0040] Alternatively, the first side 11 and the second side 12 may overlap, meaning the opening 13 is located on the second side 12. The second side 12 is closer to the ear canal, which is more conducive to the diaphragm transmitting sound into the ear canal.

[0041] By placing the vibrating structure 2 inside the outer shell 1, when the vibrating structure 2 vibrates, it transmits the vibration to the outer shell 1. The outer shell 1 is worn on the ear, and the second side 12 fits against the ear. The vibration is transmitted to the temporal bone through the ear, achieving the effect of bone conduction. The vibrating structure 2 vibrates inside the outer shell 1. Since the inner shell 1 and the vibrating diaphragm 14 form a closed space, the vibration of the vibrating structure 2 causes the air inside the outer shell 1 to vibrate together. The breathing effect generated by the air vibration drives the vibrating diaphragm 14 to vibrate together. The sound of the vibrating diaphragm 14 is transmitted through the ear canal, achieving air conduction.

[0042] This application uses only one sound source. Compared to the separate sound transmission structures of bone conduction and air conduction, which require two sound-generating devices, this application not only reduces the size and weight of the headphones but also lowers production costs. Wearing them is simple; just place the outer shell 1 into the ear. The headphones are easy to wear, and due to their small size and light weight, they have minimal impact on the ears, improving the wearing experience and allowing for extended use.

[0043] In some embodiments, the number of controllers 3, housing 1, and vibration structure 2 are all in one-to-one pairs, and the two controllers 3 are fixedly connected together by a connecting cable 5. When worn, the connecting cable 5 hangs around the neck, pulling on the two controllers 3, reducing the pulling force of the controllers 3 on the connecting tube 4, and thus reducing the pulling force of the connecting tube 4 on the housing 1, thereby improving the comfort of wearing the headphones.

[0044] Specifically, there is one controller 3 and the other is a power bank. The controller 3 and the power bank are connected together by a connecting cable 5. The controller 3 and the power bank are connected to the two outer shells 1 one by one by a connecting tube 4.

[0045] In some embodiments, the vibrating structure 2 abuts against the interior of the outer shell 1 corresponding to the second side 12. This contact between the vibrating structure 2 and the second side 12 improves the transmission of vibrations to the second side 12, thus enhancing the bone conduction effect.

[0046] In some embodiments, the controller 3 is provided with a button 31, which is electrically connected to the transmission line. The button 31 is provided to facilitate user operation of the headphones, such as adjusting the volume or switching songs.

[0047] In some embodiments, the vibration structure 2 includes a cylinder 21 and a vibrating element 22; the outer wall of the cylinder 21 abuts against the inner wall of the outer shell 1; the vibrating element 22 is fixedly connected inside the cylinder 21. The vibrating element 22 is located inside the cylinder 21, and the cylinder 21 is installed inside the outer shell 1. During production, the cylinder 21, the vibrating element 22, and the outer shell 1 can be produced first and / or simultaneously to improve production efficiency. The cylinder 21 and the vibrating element 22 are assembled and then installed as a whole into the outer shell 1, which facilitates installation and replacement.

[0048] In some embodiments, the cylinder 21 has a first end 211 and a second end 212, and a cover plate 23 is abutting on the first end 211; the cover plate 23 abuts against the inner wall of the outer shell 1 corresponding to the second side 12. The cover can protect the vibrating components inside the cylinder 21.

[0049] In some embodiments, a groove is provided on the edge of the opening 13 for the edge of the diaphragm 14 to be engaged. By providing the groove, the connection between the diaphragm and the opening can be made more secure. At the same time, the groove increases the connection area between the diaphragm 14 and the outer shell 1, thus improving the airtightness of the connection between the diaphragm 14 and the outer shell 1.

[0050] In some embodiments, the vibrating element 22 includes: a substrate 221, a coil 222, a magnet 223, a vibrating cover 224, and a connecting piece 225; the substrate 221 is fixedly connected to the second end 212, and the substrate 221 is electrically connected and fixed to the coil 222; the vibrating cover 224 is located inside the cylinder 21, and the vibrating cover 224 is fixedly connected to the inner wall of the cylinder 21 through the connecting piece 225; the magnet 223 is adsorbed and fixed on the vibrating cover 224, and a portion of the magnet 223 extends into the area enclosed by the coil 222.

[0051] The coil 222 on the substrate 221 generates an alternating magnetic field, which in turn drives the magnet 223 to move. The movement of the magnet 223 drives the vibration cover 224 to vibrate. The vibration cover 224 drives the connecting piece 225 to vibrate. The connecting piece 225 drives the cylinder 21 to vibrate, which in turn drives the outer shell 1 to vibrate. The outer shell 1 is worn in the ear. The second side 12 of the outer shell 1 fits against the temporal bone of the human body. Therefore, the vibration of the outer shell 1 can be transmitted through the human bone to achieve bone conduction.

[0052] Since the inside of the outer shell 1 and the vibrating diaphragm 14 form a closed space, the vibration of the vibrating cover 224 causes the air inside the outer shell 1 to vibrate together. The breathing effect generated by the air vibration drives the vibrating diaphragm 14 to vibrate together. The sound of the vibrating diaphragm 14 is transmitted through the ear canal, realizing air transmission.

[0053] The vibrating component 22 has a compact structure and a reasonable design. The rotating component can be placed inside the cylinder 21 as a module, and any damaged rotating component can be directly removed and replaced, which is convenient for replacement and installation.

[0054] Specifically, the controller 3 is equipped with a circuit board, and the button 31 is electrically connected to the base plate 221 through the circuit board.

[0055] In some embodiments, a vent hole is provided on the side wall of the cylinder 21, and the vent hole is close to the opening 13. The vent hole helps to transmit the air vibration generated by the vibration of the vibrating cover 224 to the vibrating diaphragm 14, thereby driving the vibration of the vibrating diaphragm 14 and improving the vibration sensitivity of the vibrating diaphragm 14.

[0056] In some embodiments, demagnetizing plates 6 are fixedly connected to both the diaphragm 14 and the magnet 223. The two demagnetizing plates 6 can improve sound quality and energy efficiency, enhance high-frequency details, and make the voice coil vibrate more accurately on the diaphragm by stabilizing the magnetic field, reducing transient response delay and improving high-frequency resolution (such as sibilance in human voices and overtones in musical instruments).

[0057] The above are merely optional embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of this utility model.
