Description

Technical Field

[0001] The utility model relates to the field of wireless earphones, and particularly relates to a neck-hanging structure for earphones. Background Art

[0002] Bone conduction is a sound conduction method, that is, sound is converted into mechanical vibrations of different frequencies and 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 without damaging the eardrum, and thus are loved by the majority of consumers.

[0003] However, the existing bone conduction earphones are generally of a neck-hanging structure, and correspondingly, there are the following problems: 1. When exercising, the neck-hanging part often rubs against the neck, resulting in discomfort. The main factor is that an elastic support is provided at the position of the neck-hanging part to make the neck-hanging part provide an inward bending pressure to ensure comfortable wearing; 2. In the existing round rod-shaped neck-hanging part, after sweating during exercise, the problem of adhesion between the neck-hanging part and the neck will occur, affecting the use experience. Content of the Utility Model

[0004] The main purpose of the utility model is to propose a neck-hanging structure for earphones, aiming to improve the existing neck-hanging structure, reduce the contact area between the neck-hanging part and the neck, and at the same time facilitate the discharge of sweat to avoid the problem of the neck-hanging part fitting with the neck.

[0005] To achieve the above object, the utility model proposes a neck-hanging structure for earphones, including:

[0006] A neck-hanging part for contacting with the human neck, and the neck-hanging part is arc-shaped;

[0007] A first housing provided at both ends of the neck-hanging part, the end of the neck-hanging part is connected to the lower part of the rear wall of the first housing, and the first housing is provided with a first electronic component;

[0008] A second housing connected to the first housing through an earhook, and a bone conduction speaker is installed in the second housing,

[0009] The rear end of the earhook is connected to the upper part of the front wall of the first housing,

[0010] The front end of the earhook is connected to the middle part of the first housing,

[0011] The first housing is provided with a vibration surface for fitting with the cartilage part of the ear.

[0012] An extension block protrudes from the middle of the neck-hanging part, the extension block is in a long strip structure, and the extension block is gradually reduced in diameter from the neck-hanging part and extends outwards.

[0013] In the actual design, an extension block is provided at the neck-hanging position, and the extension block with a reduced diameter contacts the neck, thereby reducing the contact area between the neck and the rear end of the neck-hanging part, reducing friction, facilitating the discharge of sweat, and improving the user experience.

[0014] At the same time, through the reasonable cooperation relationship of the neck-hanging part, ear-hanging parts, the first housing and the second housing, the comfort of use is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] As Figures 1 to 13 shown, a neck-hanging structure for headphones includes:

[0043] A neck-hanging part 1, which is used to contact the human neck and is in an arc shape;

[0044] A first housing 2, which is provided at both ends of the neck-hanging part 1. The end of the neck-hanging part 1 is connected to the lower position of the rear wall of the first housing 2, and the first housing 2 is provided with first electronic components;

[0045] A second housing 3, which is connected to the first housing 2 through an earhook 4, and a bone conduction speaker 37 is installed in the second housing 3,

[0046] The rear end of the earhook 4 is connected to the upper position of the front wall of the first housing 2,

[0047] The front end of the earhook 4 is connected to the middle position of the first housing 2,

[0048] The first housing 2 is provided with a vibrating surface, which is used to fit against the cartilage part of the ear.

[0049] In the actual design, the first housing 2 and the second housing 3 are connected by the ear hook 4, and the end of the neck strap 1 is connected to the lower position of the rear wall of the first housing 2. The rear end of the ear hook 4 is connected to the upper position of the front wall of the first housing 2, thus forming a staggered structure, enabling the ear hook 4 to fit the head, which facilitates the wearing of the 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 daily wearing of glasses;

[0050] 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;

[0051] Among them, the neck strap 1 extends backward and downward from the first housing 2, enabling the neck strap 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. As a result, the second housing 3 is in a tilted position. Under the inward elastic force of the ear hook 4, the vibration surface of the second housing 3 fits the cartilage part, thus improving the bone-conducted sound wave transmission and reducing the problem of sound quality distortion, enhancing the use experience of the bone conduction earphone.

[0052] Specifically, an extension block 11 protrudes from the middle of the neck strap 1, and the extension block 11 is in a long strip structure. Through the arrangement of the extension block 11, the problem of the neck strap 1 sticking to the neck caused by sweat during movement is reduced, and the air permeability between the neck and the neck strap 1 is improved.

[0053] Specifically, the extension block 11 is integrally injection molded from silicone and has a ventilation groove 12 in the middle. This improves the wearing comfort and at the same time enhances the air permeability, avoiding the adhesion problem caused by running.

[0054] Specifically, the extension block 11 is gradually reduced in diameter as it extends outward from the neck strap 1, further reducing the contact area between the neck and the neck strap 1, achieving the function of the neck strap 1 while avoiding the sticky feeling after the sweat dries.

[0055] Specifically, the two ends of the neck strap 1 are provided with a first arc portion 51, the first housing 2 is provided with a second arc portion 52 that cooperates with the first arc portion 51, the neck strap 1 is provided with a first insertion portion 61 at the first arc portion 51, and the first housing 2 is provided with a first insertion groove 62 that cooperates with the first insertion portion 61;

[0056] When the first insertion portion 61 extends into the first insertion groove 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 ear hook 4 and the first housing 2, making the earphone more aesthetically pleasing.

[0057] 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;

[0058] The first housing 2 is provided with a first card hole 64. The first insertion part 61 passes through the first insertion slot 62 and then extends into the first housing 2. The first insertion part 61 is provided with a first through hole 65 that cooperates with the first card hole 64. A first limit 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, thereby realizing the limit. At the same time, the first arc part 51 and the second arc part 52 exert a predetermined elastic pressure, thereby ensuring stable combination;

[0059] The inner wall of the first insertion slot 62 is provided with an inwardly protruding first clamping part 71. The first insertion part 61 is provided with a first limiting part 72 that cooperates with the first clamping part 71;

[0060] The position where the first insertion part 61 is provided with the first through hole 65 is the first card seat 73. The thickness of the first card seat 73 is one-half of the thickness of the first insertion part 61. Thereby realizing the mutual cooperation between the neck strap and the first housing 2. First, the elastic fit of the first arc part 51 and the second arc part 52 plays a first waterproof effect;

[0061] The first elastic ring, such as a sealing ring, plays a second waterproof effect;

[0062] Among them, the cooperation between the first insertion part 61 and the first insertion slot 62 can realize the mutual fixation between the neck strap and the first housing 2.

[0063] The first insertion part 61 and the neck strap 1 are integrally injection-molded.

[0064] Specifically, the first housing 2 is provided with a first inner cavity. The first inner cavity is provided with a first PCB board 25. 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.

[0065] Among them, 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;

[0066] 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. Reducing power consumption.

[0067] 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 is in contact with the inner wall of the light-transmitting hole 8 (where a snap-fit structure is adopted to play a waterproof role). The first PCB board 25 is welded with an LED lamp 82 at the position of the light-transmitting blocking portion 812.

[0068] 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, improving the safety of night running.

[0069] 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;

[0070] 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;

[0071] The first cavity 23 is provided with a first socket 28, and the first upper cover 24 is provided with a first plug post 29 matching the first socket 28, thus realizing the assembly of the first housing 2. Among them, the first PCB board 25 is adapted to the shape of the first cavity 23 or the shape of the remaining space, thus realizing conformal snap-fit fixation.

[0072] Among them, the first upper cover 24 and the first opening 21 are fixed by ultrasonic welding or glue bonding to achieve waterproofing.

[0073] Specifically, a limiting step seat 74 is provided at the rear end of the first plugging portion 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 plugging portion.

[0074] 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.

[0075] 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 position of the auricle. Among them, the bending end can be referenced by hooking the inner wall position of the auricle.

[0076] Specifically, the first end portion 41 is provided with a third arc portion 53, and the first housing 2 is provided with a fourth arc portion 54 that cooperates with the third arc portion 53; the second end portion 42 is provided with a fifth arc portion, and the second housing 3 is provided with a sixth arc portion 56 that cooperates with the fifth arc portion 55; the first end portion 41 is provided with a second insertion portion 91, and the first housing 2 is provided with a second insertion slot 92 that cooperates with the second insertion portion 91; the second end portion 42 is provided with a third insertion portion 93, and the second housing 3 is provided with a third insertion slot 94 that cooperates with the third insertion portion 93; thus, the mutual cooperation among the ear hook 4, the first housing 2, and the second housing 3 is realized.

[0077] The cooperation relationship between the second insertion portion 91 and the second insertion slot 92, and the cooperation relationship between the third insertion portion 93 and the third insertion slot 94 can refer to the cooperation relationship between the first insertion portion 61 and the first insertion slot 62.

[0078] Specifically, the third arc portion 53 and the fifth arc portion take the bending section 43 as the first reference point position, and 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 that the second housing 3 fits against the cartilage portion. The preferred embodiment is 8 degrees, and it has been tested that 5 degrees to 15 degrees can be applicable to different types of users, such as thin or fat people. The ear hook 4 body has a certain elasticity, so it has a degree of deformation, and its reference is based on the non-deformed state of the ear hook 4.

[0079] Specifically, with the Z-axis direction as the reference, the height of the inner side wall of the bending end and the lowermost end of the third arc portion 53 is h1, and the height of the inner side wall of the bending end and the lowermost end of the fifth arc portion is h2. The height of h2 is 0.75 times to 0.85 times that of h1. After 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 ear hook 4 part, that is, the ear hook 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 the stable output of sound quality. The ear hook 4 body has a certain elasticity, so it has a degree of deformation, and its reference is based on the non-deformed state of the ear hook 4.

[0080] Specifically, with the Y-axis direction as the reference, the length from the bending end to the inner side of the third arc portion 53 is a1, and the length from the bending end to the inner side of the fifth arc portion is a2. The length of a1 is 1.8 times to 2.2 times that of a2. The ear hook 4 body has a certain elasticity, so it has a degree of deformation, and its reference is based on the non-deformed state of the ear hook 4;

[0081] Thus, it is ensured to be applicable to different ear shapes. At the same time, it is convenient to wear glasses while wearing the ear hook 4.

[0082] Specifically, the diameter of the bent section 43 is smaller than the diameters of the first end portion 41 and the second end portion 42. The ear hook 4 is tapered from the bent end towards both ends, and the diameter of the second end portion 42 is larger than that of the first end portion 41, thereby reducing discomfort when wearing glasses.
