Description

Technical Field

[0001] This application relates to the field of loudspeaker technology, and specifically to an ear-hook composite conductive headphone. Background Technology

[0002] Most headphones on the market currently use air conduction and / or bone conduction as sound transmission modes. In existing composite headphones that combine bone conduction and air conduction, the vibrating component generally includes a cover for connecting the magnet. The cover is connected to the headphone shell through a vibrating plate to transmit the vibration of the magnet to the headphone shell. The addition of the cover for connecting the magnet increases the weight of the headphones, reduces wearing comfort, and increases production costs. Utility Model Content

[0003] This application provides an ear-hook composite conductive headphone, which aims to solve the problem of high cost of existing headphones.

[0004] In one embodiment, an ear-hook composite conductive headphone is provided, comprising:

[0005] The housing has an opening for mounting the diaphragm, and the housing and the diaphragm enclose a sealed vibration cavity.

[0006] A substrate is mounted inside the vibration cavity; the substrate is electrically connected to a power source.

[0007] A coil, the coil being fixed on the substrate and electrically connected to the substrate;

[0008] A magnet having a cavity into which a coil can extend; the magnet is fixedly connected to the inner wall of the vibration cavity via a connecting piece.

[0009] The power source is a portable power bank, i.e., a battery.

[0010] In one embodiment, a connecting housing is further included, which is detachably connected to the outer casing via a connecting pipe, and the power source is located inside the connecting housing.

[0011] In one embodiment, the outer casing has a connection hole; a snap-fit ​​block is inserted and fixed inside the connecting tube, the snap-fit ​​block is snapped into the connection hole and engages with the inner wall of the connection hole.

[0012] In one embodiment, the substrate has a through hole, and the coil is fixed along the edge of the through hole.

[0013] In one embodiment, the housing includes a first housing and a second housing, which are detachably connected; the opening and the connection hole are both located on the second housing.

[0014] In one embodiment, a connecting cylinder abutting against the inner wall of the second housing is further included; the base plate is fixed to one end of the connecting cylinder, and a protective cover is fixedly connected to the other end of the connecting cylinder; the magnet and the inner wall of the connecting cylinder are both fixedly connected to the connecting piece.

[0015] Specifically, the edge of the protective cover abuts against the inner wall of the connecting cylinder.

[0016] In one embodiment, the connecting piece has a mounting hole, and the mounting hole is fitted over the outside of the magnet. The magnet has a protruding ring that abuts against the connecting piece, and a fixing ring is fitted over the magnet. The connecting piece is clamped between the protruding ring and the fixing ring.

[0017] In one embodiment, the connecting piece includes a first ring body, a second ring body, and a connecting segment; the first ring body is fixedly connected to the magnet, and the second ring body is fixedly connected to the inner wall of the connecting cylinder; one end of the connecting segment is fixedly connected to the first ring body, and the other end is fixedly connected to the second ring body.

[0018] In one embodiment, the number of connecting segments is four, and the four connecting segments are distributed at circumferential intervals along the first ring body.

[0019] In one embodiment, the connecting segment is in the form of a curved U-shape.

[0020] The beneficial effects of this application are:

[0021] By creating a cavity in the magnet, a coil can be inserted into the cavity. The changing magnetic field generated by the coil can drive the magnet to move. Therefore, the vibration of the magnet can be transmitted to the outer shell through the connecting piece. When the user wears the headphones, the outer shell fits against the skull, so the sound from the vibrating outer shell can be transmitted to the cerebral cortex through the skull, achieving a bone conduction effect. At the same time, the vibration of the magnet in the sealed vibration cavity causes the air inside the cavity to vibrate as well. The vibrating air drives the diaphragm to vibrate, achieving an air conduction effect.

[0022] This application designs the magnet in the shape of a cover, avoiding the need to separately install a magnetic block for induction with the coil. By integrating the functions of the cover and the magnet into one unit, the number of components is reduced, the weight of the headphones is decreased, and wearing comfort is improved. At the same time, the reduction in the number of components lowers production costs. Attached Figure Description

[0037] This application proposes improvements and innovations, and presents the following embodiments.

[0038] In some implementations, please refer to Figures 1 to 5 An ear-hook composite conductive headphone is provided, comprising:

[0039] The outer casing 1 has an opening 13 for mounting the diaphragm 12, and the outer casing 1 and the diaphragm 12 enclose a sealed vibration cavity 11.

[0040] Substrate 2 is installed inside vibration cavity 11; substrate 2 is electrically connected to a power source.

[0041] Coil 3 is fixed on substrate 2 and is electrically connected to substrate 2;

[0042] Magnet 4 has a cavity 41 into which coil 3 can extend; magnet 4 is fixedly connected to the inner wall of vibration cavity 11 by connecting piece 5.

[0043] The power source is a portable power bank, i.e., a battery.

[0044] By providing a recessed cavity 41 to the magnet 4, the coil 3 can be inserted into the cavity 41. The changing magnetic field generated by the coil 3 can drive the magnet 4 to move. Therefore, the vibration of the magnet 4 can be transmitted to the outer shell 1 through the connecting piece 5. When the user wears the headphones, the outer shell 1 fits against the skull, so the sound from the vibrating outer shell 1 can be transmitted to the cerebral cortex through the skull, achieving a bone conduction effect. At the same time, the vibration of the magnet 4 within the sealed vibration cavity 11 causes the air inside the vibration cavity 11 to vibrate as well. The vibrating air drives the diaphragm 12 to vibrate as well, achieving an air conduction effect.

[0045] In one embodiment, a connecting shell 7 is also included. The connecting shell 7 is detachably connected to the outer shell 1 via a connecting tube 6, and the power supply is located inside the connecting shell 7. The connecting shell 7 provides a location for the installation of the power supply. When worn, the connecting tube 6 and the connecting shell 7 hang behind the ear, providing support for the earphone and making it less likely to fall off.

[0046] Specifically, the power supply and the substrate 2 are connected by wires, which pass through the connecting tube 6 to connect the power supply and the substrate 2.

[0047] In one embodiment, the outer casing 1 has a connection hole 14; a snap-fit ​​block 61 is inserted and fixed inside the connecting pipe 6, the snap-fit ​​block 61 snaps into the connection hole 14 and engages with the inner wall of the connection hole 14. Through the snap-fit ​​engagement of the snap-fit ​​block 61 and the snap-fit ​​hole, the connecting pipe 6 and the outer casing 1 can be connected together by edge.

[0048] In one embodiment, the substrate 2 has a through hole 21, and the coil 3 is fixed along the edge of the through hole 21. The through hole 21 reduces the weight of the substrate 2, thereby reducing the weight of the headphones and improving wearing comfort.

[0049] In one embodiment, the outer casing 1 includes a first casing 15 and a second casing 16, which are detachably connected; the opening 13 and the connection hole 14 are both located on the second casing 16. Dividing the outer casing 1 into the first casing 15 and the second casing 16 facilitates the installation of components such as the substrate 2 into the first casing 15 and the second casing 16, thus facilitating assembly.

[0050] In one embodiment, a connecting cylinder 17 abuts against the inner wall of the second housing 16 is also included; the substrate 2 is fixed to one end of the connecting cylinder 17, and a protective cover 18 is fixedly connected to the other end of the connecting cylinder 17; the magnet 4 and the inner wall of the connecting cylinder 17 are both fixedly connected to the connecting piece 5. The connecting cylinder 17 and the protective cover 18 can improve the protection of the substrate 2 and the cover, and at the same time improve the structural strength of the earphone.

[0051] Specifically, the edge of the protective cover 18 abuts against the inner wall of the connecting cylinder 17.

[0052] Specifically, the protective cover 18 has ventilation holes. The ventilation holes help transmit the air vibration generated by the vibration of the vibrating cover to the vibrating diaphragm 12, thereby driving the vibration of the vibrating diaphragm 12 and improving the vibration sensitivity of the vibrating diaphragm 12.

[0053] Specifically, the inner wall of the connecting cylinder 17 near the opening 13 has a groove for the protective cover 18 to be inserted. The groove improves the firmness of the connection between the cover and the connecting cylinder 17.

[0054] In one embodiment, the connecting piece 5 has a mounting hole 51, and the magnet 4 is fitted into the mounting hole 51. The magnet 4 has a protruding ring 42 that abuts against the connecting piece 5, and a fixing ring 43 is fitted over the magnet 4 for fixation. The connecting piece 5 is clamped between the protruding ring 42 and the fixing ring 43. By clamping and fixing the connecting piece 5 with the protruding ring 42 and the fixing ring 43 of the magnet 4, the connection between the connecting piece 5 and the magnet 4 is ensured to be firm, while facilitating the disassembly and assembly of the connecting piece 5.

[0055] In one embodiment, the connecting piece 5 includes a first ring 52, a second ring 53, and a connecting section 54. The first ring 52 is fixedly connected to the magnet 4, and the second ring 53 is fixedly connected to the inner wall of the connecting cylinder 17. One end of the connecting section 54 is fixedly connected to the first ring 52, and the other end is fixedly connected to the second ring 53. The vibration transmitted by the magnet 4 to the connecting cylinder 17 is transmitted through the connecting section 54. This design is simple and reasonable.

[0056] In one embodiment, there are four connecting segments 54, which are distributed circumferentially around the first ring body 52. ​​The four connecting segments 54 make the force on the magnet 4 more uniform and improve the vibration transmission effect.

[0057] In one embodiment, the connecting segment 54 is in the form of a curved U-shape. The U-shaped design of the connecting segment 54 can increase the amplitude of the magnet 4 and ensure the sound quality of the transmitted vibration.

[0058] Specifically, demagnetizing plates 8 are fixedly connected to both the diaphragm 12 and the magnet 4. The two demagnetizing plates 8 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).

[0059] 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.
