Description

Technical Field

[0001] This utility model relates to the field of smart wearable technology, and in particular to an ear-hook type of earphone. Background Technology

[0002] With the widespread use of mobile devices and the increasing demand for enjoying music, podcasts, or making calls anytime, anywhere, various types of headphones have emerged and become indispensable companions in people's daily lives. Among them, ear-hook headphones are popular among sports enthusiasts, commuters, and busy people due to their unique advantages, such as not easily falling off during exercise, convenient one-handed operation, and relatively comfortable wearing.

[0003] In existing ear-hook headphones, the angle between the earbud structure (the part that directly contacts or approaches the ear canal) and the main body of the ear hook structure is usually designed to be fixed or have only a very small, imperceptible range of adjustment. However, due to significant differences in the shape of each person's auricle, the angle of the ear canal entrance, and wearing habits, a fixed earbud angle often makes it difficult to achieve a perfect match with the user's ear structure.

[0023] In existing ear-hook headphones, the angle between the earbud structure (the part that directly contacts or approaches the ear canal) and the main body of the ear hook structure is usually designed to be fixed or have only a very small, imperceptible range of adjustment. However, due to significant differences in the shape of each person's auricle, the angle of the ear canal entrance, and wearing habits, a fixed earbud angle often makes it difficult to achieve a perfect match with the user's ear structure.

[0024] This utility model proposes an ear-hook type of headphone.

[0025] Please see Figure 1 and Figure 5 In one embodiment of this utility model, the ear-hook earphone 100 includes:

[0026] Ear hook structure 1 is configured as a bent structure to be hung on the ear;

[0027] The earphone structure 2 includes an earphone body 21 and a connecting component 22. The earphone body 21 is fixedly connected to the ear hook structure 1. The connecting component 22 is located at one end of the earphone body 21 and is a flexible structure that can be bent.

[0028] The earbud structure 3 is located at the end of the connecting component 22 away from the headphone body 21. The earbud structure 3 includes a housing 31 and a rotating seat 32 located inside the housing 31. The rotating seat 32 is located close to the connecting component 22 and is rotatably connected to the connecting component 22.

[0029] The technical solution of this utility model involves rotatably mounting the rotating seat 32 in the earbud structure 3 onto the connecting component 22 in the headphone structure 2. This allows the earbud structure 3 to rotate around the axis of the connecting component 22 at a certain angle (e.g., -60° to 60°), giving the earbud structure 3 a certain degree of rotational freedom. This allows users to rotate the earbud structure 3 according to their ear canal structure and usage habits to find the optimal insertion angle, improving wearing comfort. Furthermore, the connecting component 22 also employs a flexible structure, further providing the earbud structure 3 with greater rotational angle. When the earbud structure 3 is stretched, the connecting component 22 can absorb some of the impact force, thereby reducing the risk of hard breakage of the headphone structure 2.

[0030] Specifically, the ear hook structure 1 can be made of a shape memory alloy with good toughness (such as titanium alloy) or a flexible rubber (such as natural rubber or silicone rubber). Users can easily bend it into an arc that best suits the contours of their ears with a little force, allowing it to hang on their ears. For example, for users with larger or unusually shaped ears, the end of the ear hook structure 1 can be bent downwards or outwards to fit more snugly against the back of the ear; while for users with smaller ears, the degree of bending can be reduced to avoid the end of the ear hook pressing against the ear and causing discomfort.

[0031] It should be noted that, please refer to Figure 6 and Figure 7 The connecting component 22 acts as a bridge between the headphone body 21 and the earbud structure 3. Its flexibility allows the angle between the two to be freely adjusted within a certain range. The connecting component 22 can be made of materials such as flexible silicone tubes, memory metal wires, or flexible plastic strips. The rotating base 32 is connected to the connecting component 22 through a damped rotating shaft structure, allowing the earbud structure 3 to have a certain degree of rotational freedom. For example, it can rotate within a 60° angle range in both the left and right directions around the axis of the connecting component 22, achieving a total rotation of 120°. The rotation function allows the earbud structure 3 to be combined with the in-ear angle. When the user needs to communicate with people around them, they can easily rotate the earbud to a certain angle so that it does not completely block the ear canal, allowing them to hear the sound inside the headphones while still being able to perceive the external ambient sound.

[0032] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The connection component 22 includes:

[0033] Connecting bridge 221, made of flexible material, connects the outer shell 31 and the earphone body 21; and

[0034] Mounting base 222 is located inside the connecting bridge 221 near the rotating base 32. One end of mounting base 222 extends into the interior of housing 31, and rotating base 32 is rotatably mounted on mounting base 222.

[0035] Specifically, the connecting bridge 221 can adopt a double-layer composite structure, with an outer layer of flexible silicone and an inner layer of thermoplastic polyurethane with a certain supporting strength. The mounting base 222 can be a small injection-molded part, with a mounting hole on the side of the mounting base 222 facing the rotating base 32, and a rotating shaft protruding from the side of the rotating base 32 facing the mounting base 222. By installing the rotating shaft in the mounting hole, the rotating base 32 can rotate within a certain angle range. Understandably, the mounting base 222 can be fixed inside the connecting bridge 221 by a snap-fit ​​or threaded connection, and a groove can be provided at the corresponding position on the outer shell 31 to accommodate the extended portion of the mounting base 222. Optionally, the rotating base 32 can be designed as a "universal joint" structure, allowing for fine-tuning of the angle in multiple directions to accommodate different users' ear canal angles.

[0036] In the embodiments of this utility model, please refer to Figure 3 The mounting base 222 is provided with a mounting plug 2221. A positioning block 3121 is provided on one of the mounting plug 2221 and the housing 31, and a positioning groove 2220 is provided on the other of the mounting plug 2221 and the housing 31. The positioning block 3121 and the positioning groove 2220 cooperate. The mounting plug 2221 on the mounting base 222 and the housing 31 are connected by the cooperation of the positioning block 3121 and the positioning groove 2220 (for example, one has a raised positioning block 3121, and the other has a corresponding recessed positioning groove 2220). The shape of the positioning block 3121 and the positioning groove 2220 is not specifically limited and can be square or triangular, etc. In this way, while the rotating seat 32 realizes the rotation function, it provides precise axial and radial positioning for the mounting base 222 inside the housing.

[0037] In the embodiments of this utility model, please refer to Figure 3The outer shell 31 includes an upper shell 311 and a lower shell 312, which are interlocked to form a cavity inside each other. The inner wall of the lower shell 312 is provided with a positioning block 3121, and the outer periphery of the mounting plug 2221 is provided with a positioning groove 2220. In this design, the outer shell 31 is divided into two parts, the upper shell 311 and the lower shell 312, making the installation and disassembly of internal components more convenient. For example, components such as the rotating seat 32 can be installed in the lower shell 312 first, and then the upper shell 311 can be interlocked onto the lower shell 312 to complete the assembly of the outer shell 31. The interlocking structure between the upper shell 311 and the lower shell 312 can use a snap-fit ​​connection, eliminating the need for additional fasteners and improving assembly speed. In this embodiment, a positioning block 3121 is provided on the inner wall of the lower shell 312, and a positioning groove 2220 is provided on the outer wall of the mounting plug 2221. Thus, when the mounting plug 2221 is inserted into the lower shell 312, its outer positioning groove 2220 can precisely align and engage with the positioning block 3121 on the inner wall of the lower shell 312. This ensures the accurate position of the mounting seat 222 within the cavity, thereby guaranteeing the precise installation of the rotating seat 32 relative to the lower shell 312. For example, the positioning block 3121 can be designed in an L-shape, with the positioning groove 2220 matching it. In this case, the mounting plug 2221 can not only be positioned axially but also limited radially, preventing unnecessary displacement of the mounting seat 222 within the cavity.

[0038] In the embodiments of this utility model, please refer to Figure 3 and Figure 4 The mounting plug 2221 has an internal insertion hole 2222, which is axially aligned with the mounting plug 2221. A rotating seat 32 is fixedly disposed within the cavity, with a portion of the rotating seat 32 extending into the insertion hole 2222 to press the positioning groove 2220 on the mounting plug 2221 towards the positioning block 3121. The insertion hole 2222 can be a through hole or a blind hole located at the center of the mounting plug 2221. The portion of the rotating seat 32 extending into the insertion hole 2222 can be a slightly tapered small column or a protrusion with a bevel. When the mounting plug 2221 (with the positioning groove 2220) is inserted into the positioning block 3121 on the lower housing 312, the portion of the rotating seat 32 extending into the insertion hole 2222 generates an outward axial thrust on the mounting plug 2221, ensuring that the positioning block 3121 and the positioning groove 2220 form a locking structure, thereby improving the connection strength between the mounting plug 2221 and the lower housing 312. It is worth mentioning that for the part of the rotating seat 32 that does not extend into the insertion hole 2222, it can be bonded to the inner wall of the lower shell 312 with adhesive to further improve the connection strength between the rotating seat 32 and the lower shell 312.

[0039] In the embodiments of this utility model, please refer to Figure 4The mounting plug 2221 also has a notch 2223, which communicates with the socket 2222 and extends along the axial direction of the mounting plug 2221. The notch 2223 can be a slender groove evenly distributed along the axial direction of the mounting plug 2221, or a long strip opening penetrating the side wall of the plug. The notch 2223 provides elastic deformation space for the mounting plug 2221, which facilitates the installation of the mounting plug 2221 into the lower shell 312 and also avoids damage to the mounting plug 2221 due to excessive local force on the rotating seat 32.

[0040] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 The earbud structure 3 also includes a damping element 33, which is sleeved on the outer periphery of the rotating base 32 and has an interference fit with the wall of the jack 2222. The damping element 33 can be a flexible cylinder or annular sleeve, for example, a silicone ring, wrapped around the outer periphery of the rotating base 32. In this way, when the rotating base 32 needs to rotate, it needs to overcome a certain damping force, making the rotation adjustment of the rotating base 32 more stable and smooth, ensuring that the earbud structure 3 can stay at the required angle, and effectively suppressing the shaking, vibration or jamming of the rotating base 32 during rotation.

[0041] In the embodiments of this utility model, please refer to Figure 3 The earbud structure 3 also includes an electrical component 34 housed within the housing 31; the connecting component 22 further includes a memory steel wire 223, with its two ends connected to the earphone body 21 and the electrical component 34 respectively, and the memory steel wire 223 passing through the interior of the mounting base 222 and the rotating base 32. The memory steel wire 223 can be made of spring steel or alloy steel wire. The "memory" characteristic of the memory steel wire 223 allows it to act as a "skeleton" for flexible connections, providing necessary support while allowing the connecting component 22 to bend and rotate as needed according to the internal space of the mounting base 222, the rotating base 32, and the connecting bridge 221. For example, when the user needs to adjust the angle of the earbud structure 3, the memory steel wire 223 will bend accordingly, but will provide a reverse restoring force, so that the adjusted position can remain stable and not easily spring back or wobble. It should be noted that the two ends of the memory steel wire 223 may have tiny hooks or welding points for connection to specific electrical contact points on the earphone body 21 and the electrical component 34. In addition, the exterior of the memory steel wire 223 can be coated with an insulating material (such as polyimide) to prevent short circuits with internal electronic components.

[0042] In this embodiment of the invention, the connecting bridge 221 is made of flexible adhesive to cover the memory steel wire 223 and the mounting base 222. The flexible adhesive can be thermoplastic polyurethane (TPU) or silicone rubber, which can wrap the memory steel wire 223, wires, or mounting base 222, making the overall structure very soft and more comfortable to wear. Optionally, the outer wall of the flexible adhesive can be provided with different textures (such as frosted, dotted, or striped textures) to improve aesthetics and anti-slip properties.

[0043] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 The electrical component 34 includes a circuit board 341 and a speaker unit 342 electrically connected to the circuit board 341. A sound outlet 3111 is provided on the side edge of the upper shell 311. A tuning mesh 310 is provided on the upper shell 311 and / or the lower shell 312, and both the tuning mesh 310 and the sound outlet 3111 are positioned close to the speaker unit 342. By providing the sound outlet 3111 on the side edge of the upper shell 311, the shape of the sound outlet 3111 is not specifically limited; it can be an arc-shaped structure with a sound hole, serving as a precise "glott." Positioning the sound outlet 3111 close to the speaker unit 342 effectively conducts the sound emitted by the speaker unit 342, reducing sound reflection and standing waves in the earphone's internal cavity, resulting in clearer and purer sound. Additionally, a tuning mesh 310 can be installed on either the upper shell 311 or the lower shell 312, or both can have a tuning mesh 310. The tuning mesh 310 can be made of metal mesh (such as steel mesh) and serves as an adjustable "acoustic filter," working in conjunction with the main sound nozzle to transmit sound more directly and accurately to the ear. The circuit board 341 and speaker unit 342 are listed as electrical components 34 and integrated within the cavity of the earbud shell 31, giving the earbud assembly not only rotational adjustment capabilities but also complete electroacoustic conversion capabilities. The circuit board 341 can be a flexible printed circuit board (FPC) or a standard printed circuit board (PCB). Using a flexible circuit board 341 allows it to adapt to any shape of space within the shell 31, further reducing the overall volume of the earbud structure 3.

[0044] In the embodiments of this utility model, please refer to Figure 2The earphone body 21 includes a main board 211 and a protective sleeve 212. The main board 211 is located inside the protective sleeve 212 and is electrically connected to the electrical component 34 via wires, which pass through the interior of the connecting component 22. In this embodiment, the earphone body 21 includes a main board 211 and a protective sleeve 212. The main board 211 can be a multi-layer PCB board, integrating a Bluetooth module, audio decoding chip, processor, etc. The protective sleeve 212 is a plastic or metal shell 31, etc. The main board 211 can be fixed inside the protective sleeve 212 by clips or screws. In addition, the interior of the protective sleeve 212 may also be provided with a heat dissipation structure and shock-absorbing pads to dissipate heat from the main board 211 and protect it. The shape of the protective sleeve 212 is not specifically limited and can be square or round, etc., to enclose the wires and main board 211 inside the protective sleeve 212, protecting them from direct damage from the external environment (such as sweat and dust) and physical impact. The wires can be bound together with the memory steel wire 223 and run together inside the connecting component 22. The two ends are connected to the main board 211 and the electrical component 34 respectively, so as to realize the electrical connection between the main board 211 and the electrical component 34.

[0045] In the embodiments of this utility model, please refer to Figure 1 , Figure 6 and Figure 7 The ear hook structure 1 includes a suspension member 11 and an auxiliary member 12. The suspension member 11 connects the earphone body 21 and the auxiliary member 12. The suspension member 11 is configured as a bent structure to hang on the ear, and the auxiliary member 12 is used to house the power supply, which is electrically connected to the main board 211. The suspension member 11 can be made of materials such as polyurethane or silicone, and is configured as a flat circular sleeve structure. It may contain hidden metal wires or shape memory alloy wires to provide appropriate support and prevent the suspension member 11 from being excessively deformed or unable to recover. The auxiliary member 12 can be a small square or circular hollow structure, and the internal space is used to accommodate a lithium-ion battery or charging chip, etc., to power the main board 211 inside the earphone body 21. The electrical connection between the power supply and the main board 211 can be achieved using a flexible flat cable (FFC) or a thin wire.

[0046] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
