[0005] The housing has a receiving cavity; the housing has an opening, the opening is covered with a vibrating diaphragm, and the edge of the vibrating diaphragm is sealed to the edge of the opening;

[0006] A vibration structure, the vibration structure comprising a vibrating element and a vibration cover disposed on the vibrating element;

[0008] The controller is electrically connected to the vibrating element;

[0009] A connecting tube, the two ends of which are detachably connected to the outer shell and the controller respectively.

[0010] The connecting tube is bent into an N-shape, with the outer shell and controller spaced apart.

[0011] In one embodiment, the outer casing includes a first housing and a second housing; the first housing and the second housing are detachably connected; the opening is located on the second housing; a through hole is formed on the first housing, and the connecting pipe is detachably connected to the through hole.

[0012] In one embodiment, a slot is provided on the connecting edge of the first housing and the second housing, and the second housing is provided with a protrusion that can be engaged with the slot.

[0013] In one embodiment, the end of the connecting tube is pluggably connected to a pin, and the connecting tube is detachably connected to the through hole via the pin.

[0014] Specifically, the pin is inserted into the through hole and abuts against the through hole.

[0015] In one embodiment, the vibration cover includes a cylinder and a cover; the cover is disposed on the vibrating element; the cover has a raised ring on its side; the cylinder is sleeved and abuts against the outer side of the cover, and the connecting piece is clamped between the end of the cylinder and the raised ring.

[0016] In one embodiment, the vibration structure includes a connecting cylinder that abuts against the interior of the second housing, and the connecting piece is fixedly connected to the connecting cylinder.

[0024] The connecting plate is detachably connected to the vibrating cover. During assembly or replacement of the vibrating cover, the connecting plate can be separated and connected by disassembling or installing the vibrating cover. Compared to the existing method of fixing the connecting plate and vibrating cover, which typically involves welding, the limited space within the vibrating cover increases the difficulty of welding and the workload for workers. This application's detachable connection between the connecting plate and vibrating cover allows for quick separation and connection, reduces installation difficulty, and lightens the workload for workers.

[0025] The detachable connection between the connecting plate and the vibration cover allows for the separate production of the connecting plate and the vibration cover, followed by assembly, thus improving production efficiency. Furthermore, the detachable design simplifies the structure of these components compared to a one-piece molding arrangement. This invention simplifies the equipment used for manufacturing and processing the connecting plate and the vibration cover, reducing construction costs.

[0026] Similarly, the connecting tubes, housing, and controller are also designed with detachable connections, which simplifies the production and processing of the corresponding headphone components and reduces construction costs. Attached Figure Description

[0039] This application proposes improvements and innovations, and presents the following embodiments.

[0040] In some implementations, please refer to Figures 1 to 3 A clip-on composite conductive headphone is provided, comprising:

[0041] The outer shell 1 has a receiving cavity 11; the outer shell 1 has an opening 13, the opening 13 is covered with a vibrating diaphragm 12, and the edge of the vibrating diaphragm 12 is sealed to the edge of the opening 13.

[0042] Vibration structure 2, which includes a vibrating element 22 and a vibration cover 21 covering the vibrating element 22;

[0043] Connecting piece 6 is detachably and fixedly connected to vibration cover 21; connecting piece 6 is connected to accommodating cavity 11;

[0044] Controller 3 is electrically connected to vibrating component 22;

[0045] Connecting pipe 4, with its two ends respectively corresponding to the outer shell 1 and the controller 3, can be detachably connected.

[0046] The connecting tube 4 is bent into an n-shape. The outer shell 1 and the controller 3 are spaced apart and clamped on both sides of the ear. The opening 13 of the outer shell 1 faces the ear canal. The vibration of the diaphragm 12 is transmitted to the ossicles through the ear canal to achieve the function of air transmission of sound. The outer shell 1 is fitted inside the concha cavity, and the vibration of the outer shell 1 is transmitted to the temporal bone through the concha cavity to achieve the function of bone transmission of sound.

[0047] The connecting piece 6 is detachably connected to the vibration cover 21. During assembly or replacement of the vibration cover 21, the connection piece 6 can be separated and connected to the vibration cover 21 simply by disassembling or installing the vibration cover 21. Compared to the fixed connection of the connecting piece 6 and the vibration cover 21, existing methods typically use welding to fix the vibration cover 21 to the connecting piece 6. Due to the limited space of the vibration cover 21, welding becomes more difficult, increasing the workload for workers. This application's detachable connection of the connecting piece 6 and the vibration cover 21 allows for quick separation and connection, reduces installation difficulty, and decreases the workload for workers.

[0048] The detachable connection between the connecting piece 6 and the vibration cover 21 allows for the separate production of the connecting piece 6 and the vibration cover 21, followed by assembly, thus improving production efficiency. Furthermore, the detachable design of the connecting piece 6 and the vibration cover 21 simplifies their component structures. Compared to a one-piece molding, this application simplifies the equipment used for producing and processing the connecting piece 6 and the vibration cover 21, reducing construction costs.

[0049] Similarly, the connecting tube 4 is also designed to be detachably connected to the housing 1 and the controller 3, which simplifies the production and processing of the corresponding headphone components and reduces the investment in construction costs.

[0050] In one embodiment, the outer casing 1 includes a first casing 15 and a second casing 16; the first casing 15 and the second casing 16 are detachably connected; an opening 13 is located on the second casing 16; a through hole 14 is provided on the first casing 15, and the connecting pipe 4 is detachably connected to the through hole 14. Dividing the outer casing 1 into the first casing 15 and the second casing 16 facilitates the installation of the vibration structure 2 inside the first casing 15 and the second casing 16, and facilitates assembly. Providing a through hole 14 on the first casing 15 facilitates connection with the connecting pipe 4.

[0051] In one embodiment, a slot 151 is provided on the connecting edge of the first housing 15 and the second housing 16, and the second housing 16 is provided with a protrusion 161 that can be engaged with the slot 151. The slot 151 and the cooperating protrusion 161 facilitate quick assembly and connection of the first housing 15 and the second housing 16.

[0052] In one embodiment, the end of the connecting pipe 4 is pluggably connected to a pin 41, and the connecting pipe 4 is detachably connected to the through hole 14 via the pin 41. The detachable connection between the connecting pipe 4 and the outer shell 1 is achieved through the pin 41, which is simple in structure and reasonable in design.

[0053] Specifically, the pin 41 is inserted into the through hole 14 and abuts against the through hole 14.

[0054] In one embodiment, the vibration cover 21 includes a cylinder 211 and a cover 212; the cover 212 covers the vibrating element 22; the cover 212 has a raised ring 213 on its side; the cylinder 211 is sleeved and abuts against the outer side of the cover 212, and the connecting piece 6 is clamped between the end of the cylinder 211 and the raised ring 213. By clamping and fixing the connecting piece 6 with the cylinder 211 and the cover 212, the connection between the connecting piece 6 and the cover 212 is ensured, while facilitating the disassembly and assembly of the cylinder 211 and the cover 212.

[0055] In one embodiment, the vibration structure 2 includes a connecting cylinder 23 that abuts against the interior of the second housing 16, and a connecting piece 6 is fixedly connected to the connecting cylinder 23. The vibrating element 22 is installed inside the connecting cylinder 23, and then the connecting cylinder 23 is inserted as a whole into the receiving cavity 11 of the outer housing 1, facilitating assembly and installation. Simultaneously, the connecting cylinder 23 protects the vibrating element 22.

[0056] Specifically, the connecting piece 6 and the connecting cylinder 23 are integrally formed parts.

[0057] In one embodiment, the vibrating element 22 includes a base plate 221, a coil 222, and a magnet 223; the base plate 221 is fixed to the end of the connecting cylinder 23, and the base plate 221 is electrically connected to the controller 3; the coil 222 is electrically fixedly connected to the base plate 221; the magnet 223 is adsorbed and fixed on the inner wall of the cover 212, and a portion of the magnet 223 extends into the area enclosed by the coil 222.

[0058] 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 21 to vibrate, the vibration cover 21 drives the connecting piece 6 to vibrate, the connecting piece 6 drives the connecting cylinder 23 to vibrate, and finally drives the outer shell 1 to vibrate. The outer shell 1 is worn in the ear and 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.

[0059] Since the interior of the outer shell 1 and the vibrating diaphragm 12 form a sealed space, the vibration of the vibrating cover 21 causes the air inside the outer shell 1 to vibrate as well. The breathing effect generated by the air vibration drives the vibrating diaphragm 12 to vibrate as well. The sound of the vibrating diaphragm 12 is transmitted through the ear canal, realizing air transmission. The vibrating component 22 has a compact structure and a reasonable design.

[0060] In one embodiment, the vibrating element 22 further includes a protective cover 224, the edge of which abuts against the inner wall of the connecting cylinder 23, the protective cover 224 abuts against the second housing 16, and the edge of the opening 13 abuts against the protective cover 224. Providing the protective cover 224 effectively protects the vibrating element 22 inside the connecting cylinder 23.

[0061] Specifically, the protective cover 224 has ventilation holes. The ventilation holes help transmit the air vibration generated by the vibration of the vibrating cover 21 to the vibrating diaphragm 12, thereby driving the vibration of the vibrating diaphragm 12 and improving the vibration sensitivity of the vibrating diaphragm 12.

[0062] Specifically, the inner wall of the connecting cylinder 23 near the opening 13 is provided with a groove for the protective cover 224 to be inserted. The groove improves the firmness of the connection between the cover 212 and the connecting cylinder 23.

[0063] In one embodiment, the controller 3 includes a power bank 32 and a control board 33; the controller 3 is equipped with a button 31; both the power bank 32 and the button 31 are electrically connected to the control board 33, and the base plate 221 is electrically connected to the control board 33. The controller 3 enhances the intelligence of the headphones.

[0064] In one embodiment, demagnetizing sheets 5 are fixedly connected to both the diaphragm 12 and the magnet 223. The two demagnetizing sheets 5 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).

[0065] 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.
