Description

Technical Field

[0001] The utility model relates to the field of wireless earphones, and particularly to a rear light structure of a neckband earphone. Background Art

[0002] Bone conduction is a sound conduction method, that is, sound is converted into mechanical vibrations of different frequencies, and is transmitted through the human skull, bony labyrinth, inner ear lymph, spiral organ, auditory nerve, and auditory center to transmit sound waves. Bone conduction earphones use bone conduction technology to receive sound, close to the bone, and sound waves are directly transmitted to the auditory nerve through the bone. Therefore, the ears can be opened, and the eardrum is not damaged, so it is loved by the majority of consumers.

[0003] However, the existing bone conduction earphones generally have a neckband structure, and there are the following problems: 1. There is no light indication during night running, which is prone to danger. 2. The existing bone conduction earphones generally require IP7 waterproofing. The existing methods generally have a more complex structure or use a two-color injection molding method (the mold cost is relatively high), but the cost is relatively high. Summary of the Utility Model

[0004] The main purpose of the utility model is to propose a rear light structure of a neckband earphone, aiming to improve the structure of the existing neckband earphone, and at the same time, it can play a role of light indication, and has good waterproof performance and wearing comfort.

[0005] To achieve the above object, the utility model proposes a rear light structure of a neckband earphone, including a neckband and a first housing. The neckband is used to contact the human neck, and the neckband is arc-shaped. The first housing is arranged at both ends of the neckband. The end of the neckband is connected to the lower part of the rear wall of the first housing. The first housing is provided with a first electronic component, and the first electronic component includes a first PCB board. A light-transmitting hole is provided at a position on the rear wall of the first housing away from the neckband. A lamp post is provided in the light-transmitting hole. The lamp post includes a light-transmitting main body extending into the first light-transmitting hole and a light-transmitting blocking portion located at the rear end of the light-transmitting main body. The outer wall of the light-transmitting main body is attached to the inner wall of the light-transmitting hole. An LED lamp is welded to the first PCB board at the position of the light-transmitting blocking portion.

[0006] The first housing and the lamp post are installed separately, which can reduce the production cost of the mold, and has good sealing performance. At the same time, setting a light on the first housing can more clearly identify the runner at night, improve the safety of night running, and its structure is simple and stable, reducing the production cost of the earphone.

[0034] As Figures 1 to 13 shown, a rear light structure of a neck - hanging earphone includes:

[0035] A neck - hanging part 1 for contacting with the human neck, and the neck - hanging part 1 is arc - shaped;

[0036] A first housing 2 provided at both ends of the neck - hanging part 1. The end of the neck - hanging part 1 is connected to the lower part of the rear wall of the first housing 2, and the first housing 2 is provided with first electronic components;

[0037] A second housing 3 connected to the first housing 2 through an ear - hook 4. The second housing 3 is equipped with a bone - conduction speaker 37,

[0038] The rear end of the ear - hook 4 is connected to the upper part of the front wall of the first housing 2,

[0039] The front end of the ear - hook 4 is connected to the middle part of the first housing 2,

[0040] The first housing 2 is provided with a vibrating surface for fitting with the cartilage part of the ear.

[0041] In actual design, the first housing 2 and the second housing 3 are connected through the ear - hook 4, and the end of the neck - hanging part 1 is connected to the lower part of the rear wall of the first housing 2. The rear end of the ear - hook 4 is connected to the upper part of the front wall of the first housing 2, thus forming a staggered structure, enabling the ear - hook 4 to fit with the head, facilitating the wearing of glasses. That is, a clearance space will be formed between the ear - hook 4 and the inner wall of the upper part of the auricle, thus avoiding the wearing of daily glasses;

[0042] Moreover, 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;

[0043] Among them, the neck - hanging part 1 extends backward and downward from the first housing 2, enabling the neck - hanging part 1 to fit the position of the neck rather than the lower end of the rear wall of the head, thus improving the wearing comfort. Then, the second housing 3 is in a tilted position. Under the inward elastic force of the ear - hook 4, the vibrating surface of the second housing 3 fits with the cartilage part, thus improving the transmission of bone - conduction sound waves, reducing the problem of sound quality distortion, and enhancing the use experience of the bone - conduction earphone.

[0044] Specifically, a protruding extension block 11 is provided in the middle of the neck - hanging part 1, and the extension block 11 is in a long - strip structure. Through the setting of the extension block 11, the problem of the neck - hanging part 1 sticking to the neck caused by sweat during movement is reduced, and the air permeability between the neck and the neck - hanging part 1 is improved.

[0045] Specifically, the extension block 11 is integrally injection-molded from silica gel and is provided with a ventilation groove 12 in the middle. This improves the wearing comfort and at the same time enhances the breathability, avoiding the adhesion problem caused by running.

[0046] Specifically, the extension block 11 extends outward from the neck strap 1 and is gradually reduced in diameter, further reducing the contact area between the neck and the neck strap 1, realizing the function of the neck strap 1 while avoiding the sticky feeling after the sweat dries.

[0047] Specifically, both ends of the neck strap 1 are provided with first arc portions 51, the first housing 2 is provided with second arc portions 52 that cooperate with the first arc portions 51, the neck strap 1 is provided with first insertion portions 61 at the first arc portions 51, and the first housing 2 is provided with first insertion slots 62 that cooperate with the first insertion portions 61;

[0048] When the first insertion portion 61 extends into the first insertion slot 62, the first arc portion 51 and the second arc portion 52 are in contact and have an arc transition. This ensures the transition between the earhook 4 and the first housing 2, making the earphone more aesthetically pleasing.

[0049] Specifically, the outer peripheral wall of the first insertion portion 61 is provided with a first card slot 63, and the first card slot 63 is provided with a first elastic ring;

[0050] The first housing 2 is provided with a first card hole 64. After the first insertion portion 61 passes through the first insertion slot 62 and extends into the first housing 2, the first insertion portion 61 is provided with a first through hole 65 that cooperates with the first card hole 64. A first limiting post 66 passes through the first through hole 65 and is clamped in the first card hole 64. Its structure is similar to a mortise and tenon structure, thus realizing the limitation. At the same time, the first arc portion 51 and the second arc portion 52 exert a predetermined elastic pressure, thus ensuring stable combination;

[0051] The inner wall of the first insertion slot 62 is provided with an inwardly protruding first clamping portion 71, and the first insertion portion 61 is provided with a first limiting portion 72 that cooperates with the first clamping portion 71;

[0052] The position of the first insertion portion 61 where the first through hole 65 is provided is a first card seat 73, and the thickness of the first card seat 73 is one-half of the thickness of the first insertion portion 61. This realizes the mutual cooperation between the neck strap and the first housing 2. First, the elastic fit of the first arc portion 51 and the second arc portion 52 plays the first waterproofing effect;

[0053] The first elastic ring, such as a sealing ring, plays the second waterproofing effect;

[0054] The cooperation between the first insertion portion 61 and the first insertion slot 62 can realize the mutual fixation between the neck strap and the first housing 2.

[0055] The first plug-in part 61 and the neck strap 1 are integrally injection molded.

[0056] Specifically, the first housing 2 is provided with a first inner cavity, the first inner cavity 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. Two of the first housings 2 can be provided according to actual needs. For example, one is provided with the first control button 27 and the other is provided with the lithium battery 26. The neck strap is provided with an integrally formed cable to electrically connect the first PCB boards 25 of the two first housings 2;

[0057] The first control button 27 can be used to control the opening and closing of the speaker or the opening and closing of the LED lamp 82;

[0058] Of course, when the first control button 27 is used to control the opening or closing of the LED lamp 82, the controller can flash, be constantly on, or control the brightness, thereby realizing problems such as energy saving and reducing power consumption.

[0059] Specifically, a light-transmitting hole 8 (i.e., the upper position of the rear wall of the first housing 2) is provided at a position on the rear wall of the first housing 2 away from the neck strap. The light-transmitting hole 8 is inclined. The light-transmitting hole 8 is provided with a lamp post 81. The lamp post 81 includes a light-transmitting main 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 main 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 main body 811 fits with the inner wall of the light-transmitting hole 8 (a clamping structure is adopted to play a waterproof role). The LED lamp 82 is welded at the position of the light-transmitting blocking portion 812 of the first PCB board 25.

[0060] The first housing 2 and the lamp post 81 installed separately can reduce the production cost of the mold, and have good sealing performance. At the same time, setting lights on the first housing 2 can more clearly identify the exerciser at night during exercise and improve the safety of night running.

[0061] 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 on the first opening 21;

[0062] The inner wall of the first cavity 23 at the first opening 21 is provided with a first sealing groove 22, and the first upper cover 24 is clamped at the upper wall position of the first sealing groove 22;

[0063] The first cavity 23 is provided with a first jack 28, and the first upper cover 24 is provided with a first plug post 29 matching the first jack 28, thereby realizing the assembly of the first housing 2. 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 clamping and fixing.

[0064] The first upper cover 24 and the first opening 21 are fixed by ultrasonic welding or glue bonding to achieve waterproofing.

[0065] Specifically, a limiting step seat 74 is provided at the rear end of the first insertion part 61. The limiting step seat 74 is integrally injection-molded with the neck strap 1, that is, the silica gel is directly molded on the limiting step seat 74 to ensure the stability of the neck strap 1 and the insertion part.

[0066] Specifically, the ear hook 4 is arranged in an arc shape. The ear hook 4 includes a first end 41 and a second end 42. The first end 41 is connected to the first housing 2, and the second end 42 is connected to the second housing 3.

[0067] A bending section 43 is provided between the first end 41 and the second end 42 of the ear hook 4. The bending section 43 is located at the inner wall position of the auricle, and the bending end can be referenced with the position of hooking the inner wall of the auricle as a reference point.

[0068] Specifically, a third arc portion 53 is provided at the first end 41, and a fourth arc portion 54 is provided on the first housing 2 to cooperate with the third arc portion 53; a fifth arc portion is provided at the second end 42, and a sixth arc portion 56 is provided on the second housing 3 to cooperate with the fifth arc portion 55; a second insertion part 91 is provided at the first end 41, and a second insertion slot 92 is provided on the first housing 2 to cooperate with the second insertion part 91; a third insertion part 93 is provided at the second end 42, and a third insertion slot 94 is provided on the second housing 3 to cooperate with the third insertion part 93; thus, the mutual cooperation between the ear hook 4, the first housing 2, and the second housing 3 is realized.

[0069] The cooperation relationship between the second insertion part 91 and the second insertion slot 92, and the cooperation relationship between the third insertion part 93 and the third insertion slot 94 can refer to the cooperation relationship between the first insertion part 61 and the first insertion slot 62.

[0070] Specifically, the third arc portion 53 and the fifth arc portion take the bending section 43 as the first reference point position. The included angle α between the inner side walls of the third arc portion 53 and the fifth arc portion in the X-axis direction is greater than 5 degrees and less than 15 degrees. Thus, a predetermined pre-pressure can be applied to the second housing 3 to ensure the second housing 3 fits with the cartilage part. The preferred embodiment is 8 degrees. After testing, 5 degrees to 15 degrees can be applicable to different types of users, such as thin or fat users. The ear hook 4 body has a certain elasticity, so it has a deformation degree, and it is referenced with the ear hook 4 when it is not deformed as the benchmark.

[0071] Specifically, with the Z-axis direction as a reference, the height of the innermost wall of the bent end and the lowest end of the third arc portion 53 is h1, and the height of the innermost wall of the bent end and the lowest end of the fifth arc portion is h2. The height of h2 is 0.75 to 0.85 times that of h1. Through testing, this height can make the first housing 2 be stuck at the position of the posterior wall of the concha cavity, thereby reducing the load on the second housing 3 and the load on the earhook 4 portion. That is, the earhook 4 and the first housing 2 respectively form a fulcrum. At the same time, the setting of this height can make the contact area between the vibration surface of the second housing 3 and the cartilage portion of the ear the largest, ensuring stable sound quality output. The earhook 4 body has a certain elasticity, so it has a degree of deformation, and its reference is based on the state when the earhook 4 is not deformed.

[0072] Specifically, with the Y-axis direction as a reference, the length from the bent end to the inside of the third arc portion 53 is a1, and the length from the bent end to the inside of the fifth arc portion is a2. The length of a1 is 1.8 to 2.2 times that of a2. The earhook 4 body has a certain elasticity, so it has a degree of deformation, and its reference is based on the state when the earhook 4 is not deformed;

[0073] Furthermore, it ensures applicability to different ear shapes. At the same time, it is convenient to wear glasses while wearing the earhook 4.

[0074] Specifically, the diameter of the bent section 43 is smaller than the diameters of the first end 41 and the second end 42. The earhook 4 is arranged with a gradually decreasing diameter from the bent end towards both ends, and the diameter of the second end 42 is larger than that of the first end 41, thereby reducing discomfort when wearing glasses.

[0075] Specifically, the second housing 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; a second sealing groove 32 is provided on the inner wall of the second cavity 33 at the second opening 31, and the second upper cover 34 is stuck at the position of the upper wall of the second sealing groove 32; the second cavity 33 is provided with a second jack, and the second upper cover 34 is provided with a second plug column that matches the second jack.

[0076] Specifically, the second cavity 33 is provided with a positioning cavity 36 for installing a bone conduction speaker 37. The sounding surface 35 of the bone conduction speaker 37 is located on the vibration surface, and the bone conduction speaker 37 can be fixed by means of pasting.

[0077] Specifically, a second PCB board is welded to the wall surface of the bone conduction speaker 37 away from the sounding surface 35. The second PCB board is provided with a second control button 39. The second control button is a touch button or a press button, and the second control button is located at the position of the second upper cover 34.

[0078] Specifically, another second housing 3 is provided with a bracket 381, and two spaced microphones 38 are installed on the bracket 381. The second upper cover 34 is provided with limiting cavities for accommodating the microphones 38. The two limiting cavities are respectively provided with vertically arranged sound pickup holes 382 and horizontally arranged sound pickup holes 382, thereby realizing multi-dimensional sound acquisition and reducing the problem of unclear sound.

[0079] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
