Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to an ear clip-on headphone. Background Technology

[0002] In the consumer electronics field, clip-on headphones have gained widespread attention due to their advantages such as not needing to be inserted into the ear canal, convenient wearing, and reduced pressure on the ear canal. Their unique wearing method makes them suitable for various scenarios such as sports and office work, meeting users' needs for headphone comfort and portability. As the core component of headphones, the driver unit radiates sound waves in both forward and backward directions during operation. The sound waves radiated in the front directly act on the ear canal to transmit sound signals, while the sound waves radiated in the rear (i.e., rear cavity sound) can easily cause a series of problems if not handled properly.

[0003] In traditional clip-on earphones, the lack of targeted isolation design within the shell's internal cavity structure easily leads to acoustic interference between the two drivers. Each driver needs a relatively independent rear cavity space to ensure acoustic performance, but traditional shells often have a single, interconnected structure, allowing the rear cavities of the two drivers to communicate through internal gaps. This results in muddy sound quality and loss of depth, negatively impacting the user's listening experience. Utility Model Content

[0004] The main purpose of this invention is to propose an ear clip-on earphone, which aims to solve the technical problem of unreasonable internal cavity design in related technologies.

[0005] To achieve the above objectives, this utility model proposes an ear clip-on earphone, comprising a clamping member, a first earphone body, and a second earphone body, wherein the second earphone body is located opposite the first earphone body, and the clamping member connects the first earphone body and the second earphone body respectively. The first earphone body includes:

[0006] The housing has a cavity, and the inner wall of the cavity has a protrusion.

[0007] A sound-generating unit, comprising two speaker modules and a bracket housed within the cavity, wherein the bracket abuts against the protrusion;

[0008] The protrusion is configured to support the sound-generating unit and, together with the bracket, isolates the rear cavities of the two speaker modules.

[0009] In one embodiment, the extending direction of the protrusion is consistent with the extending direction of the sound-emitting channel of the sound-emitting unit.

[0010] In one embodiment, the protrusion is a continuous curved surface from the end near the clamping member to the end away from the clamping member.

[0011] In one embodiment, the protrusion includes two protruding sections, and the housing also has a wire-passing hole. The two protruding sections are symmetrically arranged along the axis of the wire-passing hole.

[0012] In one embodiment, the inner wall of the cavity is provided with two protrusions, which abut against the sound-generating unit respectively, and the two protrusions are symmetrically arranged along the other hole axis of the wire hole.

[0013] In one embodiment, the inner wall of the cavity is further provided with two spaced-apart limiting segments. The two limiting segments are located at one end of the inner wall of the cavity near the protrusion, and the two limiting segments enclose an area through which the power supply line passes.

[0014] In one embodiment, the housing is further provided with two vent holes, which are respectively connected to the cavity and the outside. The vent holes are symmetrically arranged along the center of the cavity.

[0015] In one embodiment, the opening cross-section of each of the vent holes is square.

[0016] In one embodiment, the first earphone body further includes two waterproof membranes, each of which is disposed on the inner periphery of one of the vent holes.

[0017] In one embodiment, the housing includes an upper shell and a lower shell. The upper shell has the protrusion inside and is connected to the clamping member. The inner cavity of the upper shell and the inner cavity of the lower shell surround each other to form the receiving cavity. The upper shell and the lower shell are detachably connected.

[0018] The ear-clip earphone provided by this utility model solves the problems of poor sound quality, sound leakage, and insufficient structural stability caused by the ineffective isolation of the rear cavity of the sound unit in traditional ear-clip earphones by providing a protrusion on the inner wall of the shell cavity of the first earphone body. The protrusion abuts against the sound-generating unit inside the cavity to jointly isolate the rear cavity of the sound-generating unit. Specifically, the ear-clip earphone connects the first earphone body and the second earphone body through a clamping component to form an ear-clip wearing structure. The shell of the first earphone body has a cavity to accommodate the sound-generating unit. The protrusion on the inner wall of the cavity directly abuts against the sound-generating unit. The contact between the protrusion and the sound-generating unit effectively isolates the rear cavity of the sound-generating unit, effectively reducing sound reflection and interference in the rear cavity, making the sound purer and clearer, and significantly improving the sound quality performance. In addition, the isolation of the rear cavity can also reduce the amount of sound leakage, reduce interference to the surrounding environment, and enhance the ability to block external noise, further optimizing the listening experience. At the same time, the protrusion provides stable support and positioning for the sound-generating unit, reducing the displacement of the sound-generating unit during vibration or wearing, and enhancing structural stability.

[0030] This utility model proposes an ear clip-on headphone 1000.

[0031] Please see Figure 1 In one embodiment of the present invention, the ear clip-on earphone 1000 includes a clamping member 6, a first earphone body 1, and a second earphone body 5. The second earphone body 5 is located on the opposite side of the first earphone body 1. The clamping member 6 connects the first earphone body 1 and the second earphone body 5 respectively. The first earphone body 1 includes a housing 11 and a sound-generating unit 12. The housing 11 has a cavity, and the inner wall of the cavity has a protrusion 2. The sound-generating unit 12 includes two speaker modules and a bracket housed in the cavity. The bracket abuts against the protrusion 2. The protrusion 2 is configured to support the sound-generating unit 12 and, together with the bracket, isolates the rear cavity of the two speaker modules.

[0032] In this embodiment, it should be noted that the sound-generating unit 12 includes two opposing speaker modules, which are separated by a bracket, thus allowing the rear cavities of the two speaker modules to be independently arranged. However, in related technologies, the cavity of the earphone shell 11 is often a single, interconnected structure, making it easy for the rear cavities of the two speaker modules to communicate through internal gaps in the shell 11. This can easily lead to superimposed or canceling interference effects between the two speaker modules, resulting in muddy sound, loss of layering, weakening the sound quality advantage between the two speaker modules of the sound-generating unit 12, reducing the user experience of the earphones, and affecting the overall user experience. It is understood that the shell 11 is used to house the sound-generating unit 12, which includes two opposing speaker modules and a bracket, with the bracket located between the two speaker modules to separate their rear cavities. The material of the shell 11 includes, but is not limited to, polycarbonate, polypropylene, and ABS (acrylonitrile-butadiene-styrene copolymer). The protrusion 2 is disposed on the inner wall of the cavity of the housing 11. When the sound-generating unit 12 (especially its support) is assembled in the cavity, the protrusion 2 directly abuts against the support, forming a tight contact structure. This contact can block the airflow between the rear cavity of the sound-generating unit 12 and the outside or other cavities of the earphone, thereby jointly isolating the rear cavity and preventing sound leakage (such as low-frequency sound wave loss) or external noise from entering the rear cavity, ensuring the integrity and purity of the sound quality. It should be noted that the inner wall side of the cavity where the protrusion 2 is located is the side of the housing 11 closest to the clamping member 6, that is, the inner wall side of the cavity where the protrusion 2 is located is the side of the housing 11 corresponding to the rear cavity of the sound-generating unit 12. This will not affect the sound-generating direction and sound propagation path of the sound-generating unit 12, while effectively isolating the rear cavity of the sound-generating unit 12. The protrusion 2 can be disposed on the inner wall of the cavity by injection molding or integral molding, which is not limited here.

[0033] The ear-clip earphone 1000 provided by this utility model solves the problems of poor sound quality, sound leakage, and insufficient structural stability caused by the ineffective isolation of the rear cavity of the sound unit 12 in traditional ear-clip earphones 1000. Specifically, the ear-clip earphone 1000 connects the first earphone body 1 and the second earphone body 5 through a clamping member 6 to form an ear-clip wearing structure. The shell 11 of the first earphone body 1 has a cavity to accommodate the sound unit 12. The protrusion 2 on the inner wall of the cavity directly abuts against the sound unit 12. The contact between the protrusion 2 and the sound unit 12 effectively isolates the rear cavity of the sound unit 12, effectively reducing sound reflection and interference in the rear cavity, making the sound purer and clearer, and significantly improving the sound quality performance. Furthermore, the isolation of the rear cavity reduces sound leakage, minimizes interference with the surrounding environment, and enhances the ability to block external noise, further optimizing the auditory experience. Simultaneously, the protrusion 2 provides stable support and positioning for the sound-generating unit 12, reducing displacement of the sound-generating unit 12 during vibration or wearing, and enhancing structural stability.

[0034] In one embodiment of the present invention, the extending direction of the protrusion 2 is consistent with the extending direction of the sound-emitting channel of the sound-emitting unit 12.

[0035] In this embodiment, combined with Figure 3 and Figure 4 When the extension direction of the protrusion 2 is aligned with the sound-emitting channel, the sound waves encounter less resistance when propagating in the rear cavity of the sound-emitting unit 12, and can be transmitted more smoothly from the front cavity of the sound-emitting unit 12. The extension direction of the sound-emitting channel of the sound-emitting unit 12 is... Figure 3 The double arrows in the design reduce sound wave reflection and standing wave phenomena in the rear cavity, thereby improving sound propagation. Since the protrusion 2 is aligned with the sound-generating channel, the sound wave propagation path is more concentrated, reducing sound scattering and allowing the sound to be emitted more concentratedly from the front cavity of the sound-generating unit 12, thus improving sound directivity. It is understood that the protrusion 2 in this embodiment, along with the arc-shaped arrangement of the adaptive earphone shell 11, provides uniform support for the sound-generating unit 12. Furthermore, because the protrusion 2 is generally arc-shaped, sound waves encountering this smooth surface will undergo smooth reflection and refraction along the shape of the surface.

[0036] In one embodiment of this utility model, the end of the protrusion 2 near the clamping member 6 to the end away from the clamping member 6 is a continuous curved surface.

[0037] In this embodiment, combined with Figure 3The continuously convex protrusion 2 smoothly guides the propagation path of sound waves, reducing reflections and standing waves within the rear cavity, thereby improving the purity and clarity of the sound quality. Simultaneously, the continuously curved protrusion 2 provides uniform support, ensuring the sound-generating unit 12 maintains a fixed position during operation and reducing the impact of mechanical vibrations on the sound-generating unit 12. This uniform support improves the stability of the sound-generating unit 12 and reduces sound distortion caused by vibration. It is understood that the continuous curved surface of the protrusion 2 can be a parabolic surface or an elliptical surface; no limitation is made here.

[0038] In one embodiment of the present invention, the protrusion 2 includes two protruding sections 21, and the housing 11 is also provided with a wire hole 13. The two protruding sections 21 are symmetrically arranged along the hole axis direction of the wire hole 13.

[0039] In this embodiment, it is understood that since the protrusion 2 is located on the side of the housing 11 near the clamping member 6, the housing 11 has a wire-passing hole 13. The wire-passing hole 13 is used for the conductive wire of the sound-generating unit 12 to pass through the first earphone body 1, and connect to the circuit board of the second earphone body 5 through the internal space of the clamping member 6. The protrusion 2 is divided into two spaced-apart protruding sections 21. The two protruding sections 21 are symmetrically arranged along the axial hole direction of the wire-passing hole 13. The protruding sections 21 are used to support the sound-generating unit 12 and, together with the bracket of the sound-generating unit 12, isolate the rear cavity of the two speaker modules. Figure 3 and Figure 4 It is understandable that the wire hole 13 is elliptical in shape, and the two protruding sections 21 are symmetrically arranged along the long axis of the wire hole 13.

[0040] In one embodiment of the present invention, two protrusions 2 are provided in the inner wall of the cavity, and the two protrusions 2 respectively abut against the sound-generating unit 12. The two protrusions 2 are symmetrically arranged along the other hole axis of the wire hole 13.

[0041] In this embodiment, it is understood that, in order to accommodate the arrangement of the two speaker modules of the sound-generating unit 12, the bracket covers part of the speaker modules. To further support the sound-generating unit 12, two symmetrically arranged protrusions 2 are introduced, which can more evenly distribute the supporting force, ensuring that the two speaker modules remain stable during operation and reducing the impact of mechanical vibration on sound quality. Simultaneously, it can also optimize the propagation path of sound waves, reducing sound wave reflection and standing wave phenomena in the rear cavity, thereby further improving sound quality performance. It should be noted that the other hole axis direction in this embodiment is perpendicular to the hole axis direction in the previous embodiment.

[0042] In one embodiment of the present invention, the inner wall of the cavity is further provided with two spaced-apart limiting segments 3. The two limiting segments 3 are located at one end of the inner wall of the cavity near the protrusion 2, and the two limiting segments 3 enclose the area through which the power supply line passes.

[0043] In this embodiment, combined with Figure 3 Understandably, the limiting segment 3 is used to fix the wires and cables to ensure that the wires and cables do not become loose or shift inside the earphone, and to ensure a stable connection of the wires and cables. The limiting segment 3 protrudes from the inner wall of the cavity and is located near one of the protruding segments 21 of the protrusion 2, so that when the sound unit 12 is confined within the cavity, the wires of the sound unit 12 can pass through the area enclosed between the limiting segments 3 into the space enclosed by the clamping member 6.

[0044] In one embodiment of this utility model, the housing 11 is also provided with two vent holes 4, which are respectively connected to the cavity and the outside. Each vent hole 4 is symmetrically arranged along the center of the cavity.

[0045] In this embodiment, combined with Figure 4 The vent 4 is used to balance the air pressure inside and outside the first earphone body 1, reducing low-frequency sound attenuation caused by air pressure difference, thereby improving sound quality. It is understandable that when the sound unit 12 is working, the air pressure inside the rear cavity will change due to vibration. The vent 4 is located on the side of the housing 11 near the clamping member 6, that is, the vent 4 is located at the positions of the housing 11 corresponding to the two rear cavities of the sound unit 12. The vent 4 can balance the air pressure between the rear cavity and the outside, reducing sound distortion and insufficient low-frequency response caused by air pressure difference, thereby improving sound quality. The symmetrically arranged vent 4 can reduce the resonance phenomenon of sound waves in the rear cavity, further optimizing the sound propagation effect.

[0046] In one embodiment of this utility model, the opening cross-section of each vent hole 4 is square.

[0047] In this embodiment, the opening cross-section of the vent 4 is designed to be square. This design can reduce the reflection and resonance of sound waves in the vent 4, while providing a stable air pressure balance.

[0048] In one embodiment of the present invention, the first earphone body 1 further includes two waterproof membranes 41, each waterproof membrane 41 being disposed on the inner periphery of a vent hole 4.

[0049] In this embodiment, to further improve the waterproof and acoustic performance of the first earphone body 1, a waterproof membrane 41 is provided on the inner periphery of each vent hole 4. The material of the waterproof membrane 41 includes, but is not limited to, polytetrafluoroethylene, polypropylene, etc., and is not limited here.

[0050] In one embodiment of the present invention, the housing 11 includes an upper housing 111 and a lower housing 112. The upper housing 111 has a protrusion 2 inside and is connected to the clamping member 6. The inner cavity of the upper housing 111 and the inner cavity of the lower housing 112 surround each other to form a cavity. The upper housing 111 and the lower housing 112 are detachably connected.

[0051] In this embodiment, combined with Figure 2 It is understood that the upper shell 111 is connected to the clamping member 6. The upper shell 111 has a protrusion 2 and a wire-passing hole 13. The upper shell 111 and the clamping member 6 are connected through the wire-passing hole 13 by means of integral molding or injection molding. The upper shell 111 and the lower shell 112 can be connected by means of threaded connection, snap-fit ​​connection, etc., which are not limited here.

[0052] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope 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 patent protection scope of the present utility model.
