Description

Technical Field

[0001] The utility model relates to the field of wireless earphones, in particular to an ear hook structure for earphones. Background Art

[0002] Bone conduction is a method of sound transmission that converts sound into mechanical vibrations of varying frequencies, transmitting them through the skull, bony labyrinth, inner ear lymphatic system, spiracles, auditory nerve, and auditory center. Bone conduction headphones utilize bone conduction technology to receive sound, allowing sound waves to travel directly through the bones to the auditory nerve. This allows the ears to be opened without damaging the eardrum, making them popular with consumers.

[0003] However, existing bone conduction headphones are generally neck-hanging structures, which correspondingly have the following problems: 1. The speaker shell is generally equipped with multiple electronic components, such as batteries, and the corresponding shell is also heavy, which affects the fit of the speaker and thus the sound quality of the bone conduction headphones; 2. There is no unified standard for the fit position between the speaker shell and the ear, which affects the sound quality. Utility Model Content

[0004] The main purpose of this utility model is to propose an ear hook structure for headphones, aiming to improve the structure of existing neck-hanging headphones, reduce the weight of the speaker, thereby improving the sound quality of the speaker, avoiding problems such as resonance, and making it more comfortable to wear.

[0005] To achieve the above-mentioned purpose, the present invention proposes an ear hook structure for headphones, comprising a neck hook, a first shell, and a second shell, the neck hook being used to contact the human neck, the neck hook being in an arc shape, the first shell being provided at both ends of the neck hook, the end of the neck hook being connected to the lower position of the rear wall of the first shell, the second shell being connected to the first shell through the ear hook, the second shell being installed with a bone conduction speaker, the rear end of the ear hook being connected to the upper position of the front wall of the first shell, the front end of the ear hook being connected to the middle position of the first shell, the first shell being provided with a vibration surface, the vibration surface being used to fit the cartilage part of the ear; the ear hook being arranged in an arc shape, the ear hook comprising a first end and a second end, the first end being connected to the first shell, the second end being connected to the second shell, the ear hook being provided with a bending section between the first end and the second end, the bending section being located on the inner wall of the auricle.

[0006] In the actual design, the first shell and the second shell are connected by an ear hook, and the end of the neck hook is connected to the lower part of the rear wall of the first shell, and the rear end of the ear hook is connected to the upper part of the front wall of the first shell, thereby forming a staggered structure, so that the ear hook can fit the head, thereby facilitating the wearing of glasses. That is, a clearance space is formed between the ear hook and the inner wall of the upper part of the auricle, thereby avoiding the need to wear glasses in daily life;

[0007] The ear hook is away from the inner wall of the upper part of the auricle, which can reduce the discomfort of the auricle and thus improve wearing comfort;

[0008] The neck hook extends backward and downward from the first shell, so that the neck hook can fit the position of the neck instead of the lower end of the back wall of the head, thereby improving wearing comfort, and making the second shell in a tilted position. Under the inward elastic force of the ear hook, the vibration surface of the second shell fits the cartilage part, thereby improving the bone conduction sound wave transmission, reducing the problem of sound quality distortion, and improving the user experience of bone conduction headphones.

[0036] like Figures 1 to 13 As shown, an ear hook structure for headphones includes:

[0037] A neck hanger 1, which is used to contact the human neck and is in an arc shape;

[0038] A first shell 2, which is provided at both ends of the neck hanger 1, with the ends of the neck hanger 1 connected to the lower portion of the rear wall of the first shell 2, and the first shell 2 is provided with a first electronic component;

[0039] The second shell 3 is connected to the first shell 2 through the ear hook 4. The second shell 3 is equipped with a bone conduction speaker 37.

[0040] The rear end of the ear hook 4 is connected to the upper portion of the front wall of the first shell 2.

[0041] The front end of the ear hook 4 is connected to the middle of the first shell 2.

[0042] The first shell 2 is provided with a vibration surface, and the vibration surface is used to fit the cartilage part of the ear.

[0043] In the actual design, the first shell 2 and the second shell 3 are connected by the ear hook 4, and the end of the neck hook 1 is connected to the lower position of the rear wall of the first shell 2, and the rear end of the ear hook 4 is connected to the upper position of the front wall of the first shell 2, thereby forming a staggered structure, so that the ear hook 4 can fit the head, thereby facilitating the wearing of glasses. That is, a clearance space is formed between the ear hook 4 and the inner wall of the upper part of the auricle, thereby avoiding the wearing of glasses in daily life;

[0044] The ear hook 4 is away from the inner wall of the upper part of the auricle, which can reduce the discomfort of the auricle and thus improve the wearing comfort;

[0045] The neck hanger 1 extends backward and downward from the first shell 2, so that the neck hanger 1 can fit the position of the neck instead of the lower end of the back wall of the head, thereby improving wearing comfort, and making the second shell 3 in a tilted position. Under the inward elastic force of the ear hook 4, the vibration surface of the second shell 3 fits the cartilage part, thereby improving the bone conduction sound wave transmission, reducing the problem of sound quality distortion, and improving the user experience of bone conduction headphones.

[0046] Specifically, an extension block 11 is protruded from the middle of the neck strap 1. The extension block 11 is in a long strip-shaped structure. The provision of the extension block 11 reduces the problem of the neck strap 1 and the neck being stuck together due to sweat during exercise, and improves the air permeability between the neck and the neck strap 1.

[0047] Specifically, the extension block 11 is integrally injection-molded with silicone and is provided with a ventilation groove 12 in the middle, thereby improving wearing comfort and breathability, and avoiding the problem of adhesion caused by running.

[0048] Specifically, the extension block 11 extends outward from the neck hanger 1 and is gradually reduced in diameter, further reducing the contact area between the neck and the neck hanger 1, thereby achieving the function of the neck hanger 1 and avoiding the sticky feeling after the sweat dries.

[0049] Specifically, the two ends of the neck hanger 1 are provided with a first arc-shaped portion 51, the first shell 2 is provided with a second arc-shaped portion 52 that matches the first arc-shaped portion 51, the neck hanger 1 is provided with a first plug-in portion 61 at the first arc-shaped portion 51, and the first shell 2 is provided with a first plug-in slot 62 that matches the first plug-in portion 61;

[0050] When the first plug portion 61 extends into the first plug slot 62, the first arc portion 51 and the second arc portion 52 fit together and form an arc transition, thereby ensuring the transition between the ear hook 4 and the first housing 2 and making the earphone more aesthetically pleasing.

[0051] Specifically, the outer peripheral wall of the first plug-in portion 61 is provided with a first card slot 63, and the first card slot 63 is provided with a first elastic ring;

[0052] The first housing 2 is provided with a first locking hole 64. The first plug-in portion 61 extends into the first housing 2 after passing through the first plug-in slot 62. The first plug-in portion 61 is provided with a first through hole 65 that matches the first locking hole 64. A first limiting post 66 passes through the first through hole 65 and is locked in the first locking hole 64. Its structure is similar to a mortise and tenon structure, thereby achieving position limiting. At the same time, the first curved portion 51 and the second curved portion 52 apply a predetermined elastic pressure to ensure a stable connection.

[0053] The inner wall of the first plug-in slot 62 is provided with a first clamping portion 71 protruding inward, and the first plug-in portion 61 is provided with a first limiting portion 72 that cooperates with the first clamping portion 71;

[0054] The first through hole 65 of the first plug-in portion 61 is located at the first retaining seat 73, and the thickness of the first retaining seat 73 is half of the thickness of the first plug-in portion 61. This achieves the mutual cooperation between the neck halter and the first shell 2. First, the elastic fit between the first curved portion 51 and the second curved portion 52 achieves the first waterproof effect;

[0055] The first elastic ring acts as a sealing ring and plays a second waterproof role;

[0056] The cooperation between the first plug-in portion 61 and the first plug-in slot 62 can achieve mutual fixation between the neck strap and the first shell 2.

[0057] The first plug-in portion 61 and the neck strap 1 are integrally injection-molded.

[0058] Specifically, the first housing 2 has a first inner cavity, which is provided with a first PCB board 25, and the first PCB board 25 is provided with a lithium battery 26 or a first control button 27. The first housing 2 has two configurations, which can be configured according to actual needs, for example, one for the first control button 27 and the other for the lithium battery 26.

[0059] The first control button 27 can be used to control the speaker on and off and can also be used to turn the LED light 82 on and off;

[0060] Of course, when the first control button 27 is used to control the LED light 82 to be turned on or off, the controller can be made to flash, be constantly on, or have brightness controlled, thereby achieving energy saving and reducing power consumption.

[0061] Specifically, a light-transmitting hole 8 is provided at a position of the rear wall of the first shell 2 away from the neck strap (i.e., the upper position of the rear wall of the first shell 2), the light-transmitting hole 8 is arranged at an angle, and the light-transmitting hole 8 is provided with a lamp post 81, the lamp post 81 includes a light-transmitting body 811 extending into the first light-transmitting hole 8 and a light-transmitting blocking portion 812 located at the rear end of the light-transmitting body 811, the diameter of the light-transmitting blocking portion 812 is larger than the diameter of the light-transmitting hole 8, the outer wall of the light-transmitting body 811 and the inner wall of the light-transmitting hole 8 are fitted together (a snap-fit ​​structure is adopted to play a waterproof role), and the first PCB board 25 is welded with an LED lamp 82 at the position of the light-transmitting blocking portion 812.

[0062] The use of a split-installed first shell 2 and lamp post 81 can reduce the production cost of the mold and improve the sealing performance. At the same time, setting a light on the first shell 2 can more clearly identify the athlete when exercising at night, thereby improving the safety of night running.

[0063] Specifically, the first housing 2 includes a first cavity 23 with a first opening 21 at the upper end and a first upper cover 24 installed at the first opening 21;

[0064] The first cavity 23 is provided with a first sealing groove 22 on the inner wall of the first opening 21, and the first upper cover 24 is clamped on the upper wall of the first sealing groove 22;

[0065] The first cavity 23 is provided with a first socket 28, and the first upper cover 24 is provided with a first plug 29 that cooperates with the first socket 28, thereby realizing the assembly of the first shell 2, wherein the first PCB board 25 is adapted to the shape of the first cavity 23 or the shape of the remaining space, thereby realizing conformal snap-fit ​​fixation.

[0066] The first upper cover 24 and the first opening 21 are fixed by ultrasonic welding or glue, thereby achieving waterproofing.

[0067] Specifically, a limiting step seat 74 is provided at the rear end of the first plug-in portion 61 , and the limiting step seat 74 is integrally injection-molded with the neck hanger 1 , that is, silicone is directly molded on the limiting step seat 74 to ensure the stability of the neck hanger 1 and the plug-in portion.

[0068] Specifically, the ear hook 4 is arranged in an arc shape, and includes a first end 41 and a second end 42. The first end 41 is connected to the first shell 2, and the second end 42 is connected to the second shell 3.

[0069] The ear hook 4 is provided with a bending section 43 between the first end 41 and the second end 42 . The bending section 43 is located at the inner wall of the auricle, wherein the bending section can use the position where it hooks the inner wall of the auricle as a reference point.

[0070] Specifically, the first end portion 41 is provided with a third arc-shaped portion 53, and the first shell 2 is provided with a fourth arc-shaped portion 54 that cooperates with the third arc-shaped portion 53; the second end portion 42 is provided with a fifth arc-shaped portion, and the second shell 3 is provided with a sixth arc-shaped portion 56 that cooperates with the fifth arc-shaped portion 55; the first end portion 41 is provided with a second plugging portion 91, and the first shell 2 is provided with a second plugging slot 92 that cooperates with the second plugging portion 91; the second end portion 42 is provided with a third plugging portion 93, and the second shell 3 is provided with a third plugging slot 94 that cooperates with the third plugging portion 93, thereby achieving mutual cooperation between the ear hook 4 and the first shell 2 and the second shell 3;

[0071] The matching relationship between the second plug-in portion 91 and the second plug-in slot 92 , and the third plug-in portion 93 and the third plug-in slot 94 may refer to the matching relationship between the first plug-in portion 61 and the first plug-in slot 62 .

[0072] Specifically, the third and fifth arcuate portions 53 and 5th arcuate portions are positioned with the bend 43 as a first reference point. The angle α between the inner sidewalls of the third and fifth arcuate portions, located along the X-axis, is greater than 5 degrees and less than 15 degrees. This allows for a predetermined preload to be applied to the second shell 3 to ensure proper contact between the second shell 3 and the cartilage portion. A preferred embodiment employs a preload of 8 degrees, with testing showing that a preload of 5 to 15 degrees can accommodate different user types, such as those with thin or overweight skin. The ear hook 4 body has a certain degree of elasticity and, therefore, a degree of deformability, which is referenced to the undeformed state of the ear hook 4.

[0073] Specifically, with the Z-axis as a reference, the height of the inner sidewall of the bent section and the lowest end of the third curved portion 53 is h1, and the height of the inner sidewall of the bent section and the lowest end of the fifth curved portion is h2, with h2 being 0.75 to 0.85 times the height of h1. Testing has shown that this height allows the first shell 2 to be positioned against the posterior wall of the cavum concha, thereby reducing the weight of the second shell 3 and the ear hook 4. Specifically, the ear hook 4 and the first shell 2 each form a fulcrum. This height also maximizes the contact area of ​​the vibration surface of the second shell 3 with the cartilage of the ear, ensuring stable sound quality output. The ear hook 4 itself has a certain degree of elasticity and, therefore, a degree of deformability, which is referenced to the undeformed state of the ear hook 4.

[0074] Specifically, with the Y-axis as a reference, the length from the bent section to the inner side of the third arcuate portion 53 is a1, and the length from the bent section to the inner side of the fifth arcuate portion is a2. The length of a1 is 1.8 to 2.2 times that of a2. The ear hook 4 has a certain elasticity and therefore has a degree of deformability. The reference is based on the undeformed state of the ear hook 4.

[0075] This ensures that the ear hook is suitable for different ear shapes. At the same time, the ear hook 4 can be worn while glasses are conveniently worn.

[0076] Specifically, the diameter of the bending section 43 is smaller than the diameters of the first end 41 and the second end 42, and the ear hook 4 is gradually reduced in diameter from the bending section toward both ends, wherein the diameter of the second end 42 is larger than the diameter of the first end 41, thereby reducing discomfort when wearing glasses.

[0077] Specifically, the second shell 3 includes a second cavity 33 with a second opening 31 at the upper end and a second upper cover 34 installed on the second opening 31; the second cavity 33 is located at the inner wall of the second opening 31 and is provided with a second sealing groove 32, and the second upper cover 34 is clamped on the upper wall position of the second sealing groove 32; the second cavity 33 is provided with a second socket, and the second upper cover 34 is provided with a second plug column that cooperates with the second socket.

[0078] Specifically, the second cavity 33 is provided with a positioning cavity 36, and the positioning cavity 36 is used to install a bone conduction speaker 37. The sound-emitting surface 35 of the bone conduction speaker 37 is located on the vibration surface, wherein the bone conduction speaker 37 can be fixed by gluing.

[0079] Specifically, a second PCB board is welded on the wall of the bone conduction speaker 37 away from the sound-emitting surface 35 , and the second PCB board is provided with a second control button 39 , which is a touch button or a press button, and is located at the position of the second upper cover 34 .

[0080] Specifically, another second shell 3 is provided with a bracket 381, and the bracket 381 is installed with two microphones 38 set at intervals. The second upper cover 34 is provided with a limiting cavity for accommodating the microphone 38. The two limiting cavities are respectively provided with a vertically set sound pickup hole 382 and a horizontally set sound pickup hole 382, ​​thereby realizing multi-dimensional sound acquisition and reducing the problem of unclear sound.

[0081] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the practical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
