Description

Technical Field

[0001] This utility model relates to the field of headphones, and in particular to a three-dimensional combination ear clip-on headphone structure. Background Technology

[0002] Depending on how they are worn, headphones can be categorized as in-ear, semi-in-ear, and over-ear. In-ear and semi-in-ear headphones need to be inserted into the ear canal, while over-ear headphones need to cover the auricle, both of which can cause pressure on the ear.

[0003] Existing clip-on headphones are generally small in size, which limits their high and low frequencies, thus affecting the actual sound output.

[0004] Existing designs are mainly coaxial speakers for both high and low frequencies, and their sound output direction is generally achieved by side output or through a sound guide channel;

[0005] The distance between the high-frequency sound and the sound outlet is relatively long, and its sound quality deteriorates significantly after passing through the curved sound guide channel.

[0006] That is, insufficient low-frequency leakage and high-frequency extension defects.

[0007] For example, Chinese patent CN202411818543.4 describes a complex structure designed to improve the balance between bass and treble in order to achieve precise sound conduction. Utility Model Content

[0008] The main purpose of this invention is to propose a three-dimensional combination ear clip-on headphone structure, which aims to improve the existing headphone structure, thereby enhancing the stereo sound of the ear clip-on headphone, and making the transition between the high and low frequencies and the sound output channel smoother, reducing sound wave loss and improving sound wave guidance.

[0009] To achieve the above objectives, this utility model proposes a three-dimensional combined ear clip-on headphone structure, comprising:

[0010] The bracket has a positioning groove in the middle and a sound outlet on the side wall of the bracket, which extends to the positioning groove and forms a sound outlet channel.

[0011] The first loudspeaker is disposed in the positioning groove;

[0012] A second speaker, at least one of which is provided, is located at the upper and / or lower end of the bracket.

[0013] The second speaker has a sound-emitting surface, and there is a gap between the sound-emitting surface and the first speaker. The sound-emitting surface and the wall of the bracket form a sound-guiding cavity.

[0014] In the actual design, the first speaker is a planar speaker (preferably a planar tweeter), and the second speaker is a dynamic speaker. By setting the first and second speakers as modular designs and installing them on the bracket, and through the sound outlet channel on the side wall of the bracket, the sound conduction accuracy of the ear clip headphones can be improved while ensuring high and low frequencies, thus improving the sound effect of the headphones.

[0015] Specifically, in the housing of the circular ear clip headphones, the low-frequency extension and high-frequency extension are improved by increasing the number of speakers and stacking planar speakers.

[0016] This mechanism assembles two moving-coil horns and one planar horn within a spherical structure, thereby maximizing volume utilization while ensuring sound directionality. Attached Figure Description

[0032] like Figures 1 to 6 As shown, a three-dimensional combined ear clip-on headphone structure includes:

[0033] The bracket 1 has a positioning groove 13 in the middle and a sound outlet 11 on the side wall of the bracket 1. The sound outlet 11 extends to the positioning groove 13 and forms a sound outlet channel 12.

[0034] The first speaker 21 (embedded) is disposed in the positioning groove 13;

[0035] At least one second speaker 22 is provided, and the second speaker 22 is located at the upper end and / or lower end of the bracket 1.

[0036] The second speaker 22 is provided with a sound-emitting surface, and there is a gap between the sound-emitting surface and the first speaker 21. The sound-emitting surface and the wall of the bracket 1 form a sound-guiding cavity.

[0037] In the actual design, the first speaker 21 is a planar speaker (preferably a planar tweeter), and the second speaker 22 is a dynamic speaker. By setting the first speaker 21 and the second speaker 22 as a modular design and installing them on the bracket 1, and through the sound outlet channel 12 on the side wall of the bracket 1, the sound conduction accuracy of the ear clip headphones can be improved while ensuring high and low frequencies, thereby improving the sound effect of the headphones.

[0038] Specifically, in the housing of the circular ear clip headphones, the low-frequency extension and high-frequency extension are improved by increasing the number of speakers and stacking planar speakers.

[0039] This mechanism assembles two moving-coil horns and one planar horn within a spherical structure, thereby maximizing volume utilization while ensuring sound directionality.

[0040] Specifically, the upper and lower walls of the bracket 1 are respectively provided with second speakers 22, which enclose the sound guiding cavity into a closed cavity.

[0041] In this embodiment of the utility model, the sound outlet channel 12 is widened from the positioning groove 13 toward the sound outlet assembly to improve the sound guiding effect. The narrowed part is used for sound collection, and the widened part is used to avoid resonance of the sound outlet 11.

[0042] Specifically, the first speaker 21 is a planar speaker, and the second speaker 22 is a dynamic speaker; other existing speakers may also be used.

[0043] In this embodiment of the present invention, the cross-sections of the first speaker 21 and the second speaker 22 are both circular, and the outer diameter of the first speaker 21 is smaller than the outer diameter of the second speaker 22.

[0044] This results in a three-dimensional sound quality and a sense of layering. At the same time, the arrangement of the three speakers can also improve the overall sound effect through the optimization of the control device.

[0045] The other two can also have an elliptical cross-section, thus achieving different sound quality effects or adapting to different headphone shells.

[0046] Specifically, the support 1 includes a horizontal wall 102 and a vertical wall 101 extending axially from the outer side of the horizontal wall.

[0047] The horizontal wall is provided with the positioning groove 13.

[0048] The sound outlet 11 is located on the vertical wall 101.

[0049] In this embodiment of the invention, the vertical walls 101 are symmetrically arranged, and the sound outlet 11 is located between the two vertical walls 101.

[0050] The horizontal wall is provided with a plurality of circumferentially distributed air passages 3, and sound waves can be transmitted through the sound outlet 11 through the predetermined spacing and the air passages 3.

[0051] In this embodiment of the utility model, the end wall of the positioning groove 13 is provided with an inwardly extending step portion 4, thereby achieving the limitation of the first speaker 21.

[0052] In this embodiment of the utility model, the wall surface of the bracket 1 opposite to the sound outlet 11 is provided with a notch 5, wherein the notch is used for the terminal of the first speaker 21 to extend and realize electrical connection.

[0053] In this embodiment of the utility model, the second speaker 22 is provided with a housing, which is fixed to the bracket 1 by glue or ultrasonic welding.

[0054] 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.
