Description

Technical Field

[0001] The present application relates to the technical field of earphones, and in particular to an earphone. Background Art

[0002] As a sound conversion device, the core function of headphones is to receive electrical signals from a media player or receiver and convert these electrical signals into sound waves that can be perceived by humans through its internal sound unit.

[0003] However, in the prior art, when the sound unit of most earphones is in operation, the diaphragm is often subjected to non-uniform air driving force due to the different positions of the through holes on the basin frame. This non-uniform air driving force causes the diaphragm to vibrate irregularly, which is the so-called rolling vibration phenomenon. This irregular vibration not only affects the movement state of the diaphragm itself, but may also cause resonance or interference of other components inside the sound unit, thereby negatively affecting the working stability of the entire sound unit. Utility Model Content

[0004] The embodiment of the present application provides an earphone that can reduce the difference in amplitude of the diaphragm at different positions when the earphone is working, reduce the occurrence of rolling vibration, make the earphone less likely to produce noise, and optimize the acoustic performance of the earphone.

[0005] An embodiment of the present application provides an earphone, the earphone comprising:

[0006] The housing is provided with a receiving cavity and a sound outlet hole and an air leakage hole connecting the receiving cavity with the outside;

[0007] a sound-emitting unit, which is arranged in the accommodating cavity and divides the accommodating cavity into a front cavity and a rear cavity, wherein the front cavity is connected to the sound outlet hole, and the rear cavity is connected to the air leakage hole; the sound-emitting unit comprises a basin frame and a diaphragm connected to the basin frame, a vibration cavity is constructed between the basin frame and the diaphragm, and two through holes connecting the vibration cavity and the rear cavity are arranged on the basin frame at intervals, and the distances between the two through holes and the air leakage hole are different; and

[0008] Two flow guide components are respectively connected to the two sides of the basin frame, each of the flow guide components cooperates with the basin frame to form a flow guide channel, and each of the flow guide channels is connected to a corresponding through hole, so that the airflow flowing out of the through hole flows through the flow guide channel and then flows to the air leakage hole, and is discharged from the air leakage hole.

[0009] Based on the earphones of the embodiment of the present application, each flow guide component is matched with the basin frame to form a flow guide channel, each flow guide channel is respectively connected to a through hole on the basin frame, and each through hole is connected to the vibration cavity and the back cavity, so that the airflow flowing out of the through hole flows through the flow guide channel and then flows to the air leakage hole, and is discharged from the air leakage hole. Compared with the conventional solution in which the airflow is directly transmitted from the through hole to the air leakage hole, the present application forms a flow guide channel to extend the air propagation path from different through holes to the air leakage hole connected to the outside world, thereby reducing the influence of the different distances between different through holes and the air leakage hole on the air propagation path, reducing the diaphragm swing and amplitude instability caused by the large difference in the air propagation path, and reducing the amplitude difference of the diaphragm at different positions during the vibration process. This improvement makes the vibration of the diaphragm closer to the ideal piston-type up and down vibration, effectively reducing the probability of rolling vibration. This not only avoids the potential impact of diaphragm vibration on other parts of the sound unit, but also ensures the stability of the sound loudness of the headphones, reduces the noise generated during operation, improves the sound perception of the headphones, and ensures the stability and durability of the headphones during long-term use.

[0018] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0019] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0020] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0021] In the description of the present application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] As a sound conversion device, the core function of headphones is to receive electrical signals from a media player or receiver and convert these electrical signals into sound waves that can be perceived by humans through its internal sound unit.

[0024] However, in the prior art, when the sound unit of most earphones is in operation, the diaphragm is often subjected to non-uniform air driving force due to the different positions of the through holes on the basin frame. This non-uniform air driving force causes the diaphragm to vibrate irregularly, which is the so-called rolling vibration phenomenon. This irregular vibration not only affects the movement state of the diaphragm itself, but may also cause resonance or interference of other components inside the sound unit, thereby negatively affecting the working stability of the entire sound unit.

[0025] To solve the above problems, please refer to Figure 1 , the present application proposes a headset 100. The headset 100 can be of various types such as open-type and closed-type. It can be seen that when the headset is an open-type headset, the user will not have a significant sense of isolation from the outside world when using the open-type headset, and has the advantages of natural and open hearing, and transparent sound, etc., while when the headset is a closed-type headset, it has the advantages of isolating external noise and more focused sound quality. In the following content, the present application still takes the headset as the type of open-type headset.

[0026] Open headphones can be air conduction headphones or bone conduction headphones. Among them, air conduction headphones have a built-in sound unit, and the sound cavity has holes for directional sound conduction. Bone conduction headphones have a built-in oscillator that can convert sound signals into vibrations and then conduct them through bones. It can be understood that open headphones should at least have a wearing state, which is a state in which the open headphones cooperate with the user's ears so that they can be relatively fixed to the user's ears. In this state, the user can obtain a more ideal listening effect.

[0027] See also Figures 2 to 4 The earphone 100 may include a housing 10, a sound unit 20 and electronic components (not shown).

[0028] Among them, a housing cavity is provided in the housing 10, and the sound unit 20 and the electronic components are provided in the housing cavity, so that the housing 10 carries and protects the sound unit 20 and the electronic components and other components. In order to ensure the hardness and rigidity of the housing 10, the housing 10 can be made of plastic material or metal material to meet the ability of various tests such as falling, twisting and sitting pressure without being damaged. It should be noted that the material of the housing 10 is not limited to a certain one. The commonly used housing 10 materials in the field can be applied to the embodiments of the utility model, and they are not listed one by one here. At the same time, the housing 10 also has an air vent 10C and a sound outlet 10D connecting the housing cavity and the outside world. The sound unit 20 cooperates with the housing 10 to define a front cavity 10A and a rear cavity 10B arranged at intervals. The front cavity 10A is connected to the sound outlet 10D, and the rear cavity 10B is connected to the air vent 10C. When the earphone 100 is worn on the ear of the user, the sound outlet 10D is arranged toward the ear canal opening of the ear, and the air outlet is arranged toward the outside of the ear, so that in the actual working process, the sound of the sound unit 20 can be transmitted to the ear of the user through the sound outlet 10D. Specifically, the number of sound outlets 10D can be two, three or more, and this application does not limit this. In order to facilitate production and assembly, the shell 10 generally includes a front shell 11 and a rear shell 12. When the front shell 11 and the rear shell 12 are connected together, the two enclose a receiving cavity.

[0029] Further, the housing 10 may specifically include a front end portion 101, a hanging portion 102 and a rear end portion 103 connected in sequence. The sound unit 20 is installed inside the front end portion 101, the electronic component is installed inside the rear end portion 103, and the interior of the hanging portion 102 is used for the electrical connection line between the sound unit 20 and the electronic component to pass through. In addition, the hanging portion 102 and the rear end portion 103 are both curved in an arc shape and form a hook shape. The hanging portion 102 and the rear end portion 103 are in contact with at least the front and rear sides of the user's ear to achieve clamping and fixing with the user's ear, so that the front end portion 101 connected to one end of the hanging portion 102 can be relatively stably set on the front side of the ear. It can be understood that the hanging portion 102 and the rear end portion 103 have a certain elasticity, so that the user can bend the hanging portion 102 and the rear end portion 103 to match the front end portion 101 with the ear.

[0030] The sound unit 20 may include a basin frame 21, a vibration system 22, a magnetic circuit system 23 and a copper ring 24. It is understandable that the vibration system 22, the magnetic circuit system 23 and the copper ring 24 are all installed on the basin frame 21, and the copper ring 24 is connected to the vibration system 22.

[0031] The basin frame 21 can be used to combine the vibration system 22, the magnetic circuit system 23 and the copper ring 24, and to fix the vibration system 22, the magnetic circuit system 23 and the copper ring 24 inside the accommodating cavity. The basin frame 21 can be constructed as an annular structure, and the material of the basin frame 21 can be a plastic material, such as ABS (Acrylonitrile Butadiene Styrene plastic). Of course, the basin frame 21 can also be a metal material, such as steel, and this application does not limit this.

[0032] The vibration system 22 may include a diaphragm 221 and a voice coil 222. The diaphragm 221 is connected to the copper ring 24 to achieve indirect connection to the basin frame 21. In actual operation, the diaphragm 221 drives the air to vibrate, so that the air can conduct sound through the sound outlet 10D. The voice coil 222 is connected to the diaphragm 221, and is located in the accommodating cavity and is spaced apart from the magnetic circuit system 23. A vibration cavity 20A is constructed between the basin frame 21 and the diaphragm 221, so that when the diaphragm 221 vibrates, sound waves are generated in the vibration cavity 20A, and these sound waves are reflected and interfered in the vibration cavity 20A.

[0033] The magnetic circuit system 23 may include a magnetic bowl 231, a magnet 233 and a washer 232. The magnetic bowl 231 may be a roughly annular bowl-shaped structure, and the magnet 233 is connected to the washer 232 and both are installed on the magnetic bowl 231. The magnetic circuit system 23 may provide the magnetic field required by the voice coil 222. The principles of the magnetic circuit system 23 and the vibration system 22 have long been disclosed in the relevant technology and will not be repeated here.

[0034] The electronic components include a battery and a circuit board. The circuit board is electrically connected to the sound unit 20 to control the vibration of the diaphragm 221 of the sound unit 20 to produce sound. The battery is electrically connected to the circuit board to provide power to the sound unit 20.

[0035] Reference Figures 2 to 4 In the present application, two through holes (21a, 21b) are arranged on the basin frame 21 at intervals, and the two through holes (21a, 21b) connect the vibration chamber 20A and the rear chamber 10B, and the distances between the two through holes (21a, 21b) and the air leakage hole 10C are different. At the same time, the earphone 100 also includes two flow guide components 30, and the two flow guide components 30 are connected to both sides of the basin frame 21. Each flow guide component 30 cooperates with the basin frame 21 to form two independent flow guide channels 40, and each flow guide channel 40 corresponds to a through hole (21a, 21b), so that the airflow flowing out of the through hole (21a, 21b) flows through the flow guide channel 40 and then flows to the air leakage hole 10C, and is discharged from the air leakage hole 10C.

[0036] Among them, in some structural forms, the flow guide member 30 and the basin frame 21 are detachably connected to form the flow guide channel 40, such as being connected in a detachable manner such as a buckle or a screw. Compared with the method of forming the flow guide channel 40 by the perforation process, in this embodiment, the flow guide channel 40 can be formed by disassembling and replacing the flow guide member 30 of different shapes, which can save the cost of the perforation process, and the detachable method is convenient for cleaning the inside of the flow guide channel 40 and reducing the blockage. Of course, in other embodiments, the two flow guide members 30 and the basin frame 21 can also be an integrated structure, which can improve the structural stability of the flow guide member 30 and the basin frame 21, and the integrated design simplifies the production process and reduces the manufacturing cost.

[0037] Specifically, the two through holes can be the first sub-hole 21a and the second sub-hole 21b, respectively. The first sub-hole 21a is closer to the air leakage hole 10C than the second sub-hole 21b. The straight-line distance between the first sub-hole 21a and the air leakage hole 10C is D1, and the straight-line distance between the second sub-hole 21b and the air leakage hole 10C is D2, so that D2 is greater than D1. The two independent guide channels 40 are connected to the first sub-hole 21a and the second sub-hole 21b, respectively. The air propagation distance from the first sub-hole 21a to the air leakage hole 10C is the sum of the length of the guide channel 40 and the straight-line distance D1 between the first sub-hole 21a and the air leakage hole 10C, and the air propagation distance between the second sub-hole 21b and the air leakage hole 10C is the sum of the straight-line distance D2 between the second sub-hole 21b and the air leakage hole 10C and the length of the guide channel 40. In this way, the length of the guide channel 40 can be made much larger than D1 and D2 to reduce the difference between D1 and D2 in the air propagation path, so that the ratio of the air propagation distance between the first sub-hole 21a and the air leakage hole 10C and the air propagation distance between the second sub-hole 21b and the air leakage hole 10C is closer to 1. At this time, the air flow resistance between the diaphragm 221 and the basin frame 21 through the two through holes (21a, 21b) to the air leakage hole 10C is closer, so as to reduce the swaying of the diaphragm 221 and the unstable amplitude.

[0038] Based on the earphone 100 of the embodiment of the present application, a guide channel 40 is formed by setting a guide component 30 to cooperate with the basin frame 21, each guide channel 40 is respectively connected to a through hole (21a, 21b) on the basin frame 21, and each through hole (21a, 21b) is connected to the vibration cavity 20A and the rear cavity 10B, so that the airflow flowing out of the through hole (21a, 21b) flows through the guide channel 40 and then flows to the air leakage hole, and is discharged from the air leakage hole 10C. Compared with the conventional solution in which the airflow is directly transmitted from the through hole to the vent hole, the present application extends the propagation path from different through holes (21a, 21b) to the vent hole 10C connected to the outside through the guide channel 40, thereby reducing the difference in the propagation path from different through holes (21a, 21b) to the vent hole 10C, reducing the swing and amplitude instability of the diaphragm 221 caused by the large difference in the air propagation path, and reducing the amplitude difference of the diaphragm 221 at different positions during the vibration process. This improvement makes the vibration of the diaphragm 221 closer to the ideal piston-like up and down vibration, effectively reducing the probability of rolling vibration. This not only avoids the potential impact of the vibration of the diaphragm 221 on other components of the sound unit 20, but also ensures the stability of the sound loudness of the earphone 100, reduces the noise generated during operation, improves the sound sense of the earphone 100, and ensures the stability and durability of the earphone 100 during long-term use.

[0039] See also Figures 2 to 4 In some structural forms, the basin frame 21 includes a frame body 211 and a surrounding plate 212. The frame body 211 is provided with two through holes (21a, 21b). The surrounding plate 212 is connected to the frame body 211 and extends toward the rear cavity 10B. The frame body 211 is used to carry other components connected to the vibration system 22, the magnetic circuit system 23, and the copper ring 24. The surrounding plate 212 can be an integral structure with the frame body 211, which can not only enhance the structural stability of the entire basin frame 21, but also simplify the manufacturing process, reduce the number of parts and assembly steps, and thus improve the processing efficiency.

[0040] The air guide member 30 is connected to the frame body 211 and the enclosure 212 respectively, and the frame body 211, the enclosure 212 and the air guide member 30 enclose to form the air guide channel 40. The air guide channel 40 formed by the enclosure provides a clear and stable path. The frame body 211 serves as the basic structure, and the enclosure 212 extends toward the rear cavity 10B, providing a clear boundary for the air guide channel 40 to facilitate the installation of the air guide member 30. The setting of the air guide member 30 guides the flow direction of the airflow, so that the air can flow efficiently and stably along the predetermined path, avoiding unnecessary energy loss and noise generation.

[0041] In some structural forms, the air leakage hole 10C is provided on the side wall of the housing 10 close to one of the air guide members 30. By providing the air leakage hole close to one of the air guide members, the air flow in the air guide channel 40 formed by the air guide member 30 can flow to the air leakage hole 10C faster, reducing the turbulence of the air flow in the rear cavity 10B, thereby reducing the generation of noise and vibration.

[0042] Furthermore, the flow guide channel 40 extends along the length direction of the flow guide member 30, and a flow guide port 33 is provided at the end of the flow guide member 30, and the flow guide port 33 is connected to the flow guide channel 40. In this way, the length of the flow guide channel 40 can be directly adjusted by directly changing the length value of the flow guide member 30. It should be noted that in another structural form, flow guide ports are provided at both ends of the flow guide member, so that the flow guide ports 33 at both ends are designed to increase the path selection of air from the flow guide channel 40 to the air leakage hole 10C, and the flexibility of air flow in the flow guide channel 40 is further enhanced.

[0043] Furthermore, the lengths of the two flow guide members 30 are equal. In this way, the two flow guide members 30 can be uniformly processed and manufactured, thereby improving production efficiency, and the installation positions of the two flow guide members 30 can be interchangeable without corresponding installation, thereby improving installation efficiency. Optionally, the length of the flow guide member 30 ranges from 1 mm to 300 mm. The length of the flow guide member 30 can be 1 mm, 50 mm, 100 mm, 200 mm, 300 mm, etc.

[0044] In other embodiments, the lengths of the two guide components 30 are not equal, and the length of the guide component 30 close to the air hole 10C is L1, and the length of the guide component 30 far from the air hole 10C is L2. The length of the guide component 30 close to the air hole 10C is greater than the length of the guide component 30 far from the air hole 10C, that is, L1 is greater than L2, so that the ratio of (L1+D1) / (L2+D2) is closer to 1, and then the air flow resistance of the air between the diaphragm 221 and the basin frame 21 through different through holes (21a, 21b) to the air hole 10C is closer, further reducing the swing of the diaphragm 221 and the unstable amplitude.

[0045] Furthermore, the length difference between the two air guide members 30 is within 200 mm. This is to avoid the length difference between the two air guide members 30 being too large, which may cause the weight of the earphone 100 to be unbalanced after installation and affect the sound effect. Specifically, the length difference between the air guide members 30 can be 1 mm, 50 mm, 100 mm, 200 mm, etc.

[0046] Optionally, the flow guide member 30 includes a first plate 31 and a second plate 32 arranged at an angle, the first plate 31 is connected to the surface of the enclosure 212 away from the frame body 211, and the second plate 32 is connected to the frame body 211. The frame body 211, the enclosure 212, the first plate 31 and the second plate 32 enclose a flow guide channel 40. Among them, the first plate 31 and the second plate 32 can be an integral structure, so as to ensure the structural stability of the flow guide member 30. The angle between the first plate 31 and the second plate 32 can be set at ninety degrees, that is, the cross section of the flow guide member 30 is set in a 7-shaped setting, so that the volume of the enclosed flow guide channel 40 can be increased, so that when the diaphragm 221 is vibrating, the volume of the air pushed by the diaphragm 221 is larger, thereby increasing the mass of the air, effectively reducing the resonance frequency f0, and improving the low-frequency performance of the earphone 100 to a certain extent. Of course, in other embodiments, the cross section of the flow guide member 30 can be set in a semicircular, U-shaped, square or other shapes.

[0047] Reference Figure 5 In another embodiment, two air leakage holes 10C are provided, one air leakage hole 10C is arranged near the outer wall of one of the flow guide components 30, and the other air leakage hole 10C is arranged near the outer wall of the other flow guide component 30. The straight-line distances between the two through holes (21a, 21b) and any one of the air leakage holes 10C are different, and during the pressure relief process, the air will flow to the outside through the nearest air leakage hole, so that the air propagation distance between the first sub-hole 21a and the nearest air leakage hole 10C is the sum of the length of the flow guide channel 40 and the straight-line distance D3 between the first sub-hole 21a and the nearest air leakage hole 10C. The air propagation distance between the second through hole 21b and the nearest air leakage hole 10C is the sum of the length of the flow guide channel 40 and the straight-line distance D4 between the second sub-hole 21b and the nearest air leakage hole 10C. Since D3 and D4 are both small, the air propagation distance between the first sub-hole 21a and the nearest air leakage hole 10 and the air propagation distance between the second sub-hole 21b and the nearest air leakage hole 10 are determined by the length of the guide channel 40, and thus the ratio of the air propagation distance between the first sub-hole 21a and the nearest air leakage hole 10 and the air propagation distance between the second sub-hole 21b and the nearest air leakage hole 10 can be easily made closer to 1. At this time, the air flow resistance between the diaphragm 221 and the basin frame 21 through the two through holes (21a, 21b) to the air leakage hole 10C is closer, further reducing the swing of the diaphragm 221 and the unstable amplitude.
