Description

Technical Field

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

[0002] True wireless earbuds are earbuds without traditional connecting wires, including Bluetooth earbuds.

[0003] With increasing demands for headphone comfort, in-ear headphones have significant limitations in actual sports or general use: 1. Long usage times can lead to reduced comfort due to negative pressure in the ear canal; 2. In-ear headphones create a relatively closed channel in the ear canal, which also affects the ear canal and thus impacts the user experience.

[0004] There are also existing ear clip-on headphones, such as Chinese patent CN202411825038.2, which only has a single first sound hole. When worn, the design requirements for the sound hole are also higher, and the design of the fit and curvature are also improved. However, when the fit is improved, the comfort of contact with the ear is reduced.

[0005] Current practices typically employ silicone structures to achieve wearing comfort, but silicone also absorbs sound, affecting the user experience. Utility Model Content

[0006] The main purpose of this invention is to propose an ear clip-on earphone, which aims to improve existing ear clip-on earphones, thereby improving sound quality and providing better wearing comfort.

[0007] To achieve the above objectives, this utility model proposes an ear clip-on earphone, comprising:

[0008] A first housing, the first housing having a first chamber for mounting a speaker;

[0009] The second housing is provided with a lithium battery and a PCB board, and the PCB board is equipped with electronic components.

[0010] A U-shaped connecting arm, the two ends of which are respectively connected to the first housing and the second housing, and the U-shaped connecting arm is equipped with cables that electrically connect the PCB board to the speaker.

[0011] The U-shaped connecting arm is an elastic plastic part.

[0012] The first housing extends along the length of the U-shaped connecting arm and is elongated.

[0013] The second housing extends along the width of the U-shaped connecting arm and is in a strip shape.

[0014] The first housing includes an inner shell and an outer shell, which together form the first chamber. The inner shell has a first sound outlet integrally formed at its length end. The loudspeaker is mounted on the outer shell, and a sound-guiding gap is provided between the loudspeaker's sound outlet surface and the inner wall of the inner shell.

[0015] The sound guide spacing is distributed at a perpendicular angle or at an inclined angle to the first sound outlet hole;

[0016] The inner shell and the sound-emitting surface are provided with a second sound-emitting hole. The inner shell has an arc-shaped shell on the wall surface away from the outer shell. The wall surface of the arc-shaped shell is a hard shell or has a flexible layer.

[0017] In the actual design, by setting both the first and second shells to be elongated, a larger contact area can be provided. At the same time, the two shells are distributed in different directions, which can reduce the force area on the ear and improve the stability of wearing.

[0018] Furthermore, to achieve stable sound quality in the headphones, the distance between the ear canal and the first sound outlet can be shortened by setting a side-emitting first sound outlet in the inner shell.

[0019] At the same time, the second sound hole can effectively reduce the resonance caused by the non-linear sound channel, improve the sound channel clarity of the first sound hole, and also play a role in relieving pressure and reducing the negative pressure in the ear canal.

[0036] like Figures 1 to 6 As shown, an ear clip-on headphone includes:

[0037] A first housing 11, wherein the first housing 11 is provided with a first chamber 110 for mounting a speaker;

[0038] The second housing 12 has a second chamber 120 for installing a lithium battery 121 and a PCB board 122, wherein electronic components are mounted on the PCB board 122.

[0039] U-shaped connecting arm 2, the two ends of which are respectively connected to the first housing 11 and the second housing 12, the U-shaped connecting arm 2 is provided with cables and electrically connects the PCB board 122 to the speaker.

[0040] The U-shaped connecting arm 2 is an elastic plastic part.

[0041] The first housing 11 extends along the length of the U-shaped connecting arm 2 and is elongated.

[0042] The second housing 12 extends along the width direction of the U-shaped connecting arm 2 and is in the shape of a strip.

[0043] The first housing 11 includes an inner housing 111 and an outer housing 112, which together form the first chamber 110. The inner housing 111 has a first sound outlet 31 integrally formed at its length end. The loudspeaker is mounted on the outer housing 112, and a sound-guiding gap 30 is provided between the sound outlet surface of the loudspeaker and the inner wall of the inner housing 111.

[0044] The sound guide spacing 30 is distributed at a perpendicular angle or at an inclined angle with the first sound outlet 31;

[0045] The inner shell 111 has a second sound outlet 32 ​​on its sound outlet surface, and the inner shell 111 has an arc-shaped shell 113 on its wall surface away from the outer shell 112. The wall surface of the arc-shaped shell 113 is a hard shell or has a flexible layer.

[0046] In the actual design, by setting both the first shell 11 and the second shell 12 to be elongated, a larger contact area can be provided. At the same time, since the two are distributed in different directions, the force area on the ear can be reduced while improving the stability of wearing.

[0047] Furthermore, in order to achieve stable sound quality in the headphones, by setting a first sound outlet 31 for side-emitting sound in the inner shell 111, the distance between the ear canal and the first sound outlet 31 can be shortened.

[0048] At the same time, the setting of the second sound hole 32 can effectively reduce the resonance caused by the non-linear sound channel, improve the sound channel clarity of the first sound hole 31, and at the same time, it can also play a role in relieving pressure and reducing the negative pressure in the ear canal.

[0049] Specifically, the inner wall of the inner shell 111 is provided with at least two stepped portions 41 spaced apart from the outer periphery of the second sound outlet 32. The inner sides of the stepped portions 41 form stepped grooves 42, and there are at least two stepped grooves. This stepped structure, combined with the use of small holes, reduces the resonance of the second sound outlet 32. That is, the cooperation between the first sound outlet 31 and the second sound outlet 32 ​​concentrates the sound vibration within the auricle.

[0050] The first sound hole 31 faces the ear canal, and the second sound hole 32 fits against the wall of the auricle, which can make the sound more three-dimensional.

[0051] In this embodiment of the invention, the first sound hole 31 is circular or flat, and the preferred embodiment is flat, thereby improving the sound quality.

[0052] Specifically, the arc-shaped shell 113 is provided with a plurality of spaced through holes 4, which are arranged opposite to the second sound outlet 32 ​​to avoid resonance and whistling.

[0053] In this embodiment of the utility model, the inner shell 111 is provided with an upwardly extending positioning post 51, and the arc-shaped shell 113 is provided with a positioning hole 52 that cooperates with the positioning post, thereby facilitating the installation and fixing of the two.

[0054] Specifically, the inner shell 111 and the arc-shaped shell 113 are fixed by ultrasonic welding or glue bonding, and the arc-shaped shell 113 and the inner shell 111 form a sub-cavity 5, thereby improving the stereo effect of the sound.

[0055] In this embodiment of the utility model, the connecting end between the U-shaped connecting arm 2 and the first housing 11 has an arc transition, which improves the aesthetics and fit of the structure and increases the installation area.

[0056] Specifically, the speaker is tilted and the sound guide spacing 30 is gradually widened from the inside toward the first sound outlet 31, thereby concentrating the sound waves in a predetermined direction and improving directional guidance.

[0057] In this embodiment of the utility model, the first sound outlet 31 is integrally formed with the inner shell 111.

[0058] Specifically, the U-shaped connecting arm 2 is provided with shape memory metal or is a plastic tube.

[0059] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using 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.
