Description

Technical Field

[0001] The utility model relates to the technical field of earphones, and more specifically to a double-flat unit module and an earphone. Background Art

[0002] The sound-generating principle of the flat-panel unit (also called flat speaker, planar unit, flat speaker or planar magnetic unit, etc.) is the isomagnetic principle, which has existed in the audio industry for a long time. Unlike the circular magnet of the dynamic coil, the magnets of the flat-panel unit are distributed in parallel on both sides of the diaphragm, and the diaphragm is provided with a conductive planar coil, or a thin metal conductor is formed by etching the circuit. When the current signal passes through, the diaphragm moves in the gap between the two flat magnets, thereby making a sound. Existing flat-panel units are difficult to drive and are prone to distortion, resulting in poor sound quality. Utility Model Content

[0026] The following will be combined with the specific embodiments of the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] It should be understood that when used in this specification and claims, the terms "include" and "comprises" indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or collections thereof.

[0028] It should also be understood that the terms used in the utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in the utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0029] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0030] like Figure 1The embodiment of the utility model provides a dual flat panel unit module, including a bracket 1 and two flat panel units 2, wherein the bracket 1 is provided with an upper mounting groove 11 and a lower mounting groove 12, wherein the two flat panel units 2 are respectively mounted in the upper mounting groove 11 and the lower mounting groove 12, and the two flat panel units 2 are arranged symmetrically in the upper and lower horizontal directions. By symmetrically arranging the two flat panel units 2 in the upper and lower horizontal directions, the mutual interference of vibrations can be reduced and the low-frequency response can be improved. At the same time, since the two flat panel units 2 are symmetrically arranged, the sound pressures are superimposed on each other, thereby generating a higher sound pressure level, and the propagation intensity of the sound energy per unit area is increased, thereby making the sound stronger and clearer. The improvement of the unit sound pressure level can better process high-intensity signals, improve the accuracy and fidelity of the signals, and reduce the occurrence of dynamic distortion.

[0031] It should be noted that the dual flat-panel unit module can be responsible for the entire full-frequency sound band alone; or by matching the frequency division circuit, the dual flat-panel unit module can be responsible for the low-frequency sound band, the medium-frequency sound band, or the high-frequency sound band.

[0032] Furthermore, the flat panel unit 2 is a ring-shaped magnetic structure or an array-shaped magnetic structure. It should be noted that the diaphragms in the ring-shaped magnetic structure or the array-shaped magnetic structure are all planar diaphragms 21 .

[0033] Furthermore, if Figure 1 As shown, the bracket 1 is provided with a cavity 13 between the upper mounting groove 11 and the lower mounting groove 12 .

[0034] The benefits of providing the cavity 13 are: improving the independence and stability of the flat panel unit 2, reducing resonance and distortion, and thus improving the clarity and accuracy of the sound quality.

[0035] Furthermore, if Figure 1 As shown, a plurality of air holes 131 are provided on the left and right walls of the cavity 13, and the shape of the air holes 131 can be round or square. The air holes 131 can reduce the back pressure effect inside the cavity 13. The back pressure refers to the reaction force generated in the air when the flat unit 2 vibrates, which has a negative impact on the sound quality. The air holes 131 can effectively reduce the back pressure effect, improve the free vibration ability of the flat unit 2, make the sound purer and more natural, and avoid distortion.

[0036] Furthermore, a tuning net 1311 is provided on the air hole 131, and the tuning net 1311 can be pasted on the air hole 131 using glue or adhesive, or fixed by screws, etc. The provided tuning net 1311 can play a role in filtering noise.

[0037] Furthermore, the diameter of the flat panel unit 2 ranges from 5mm to 20mm. By controlling the diameter of the flat panel unit 2 within this range, the size is moderate, and a wider frequency response range can be provided, with lower distortion and better sound field performance. In addition, compared with traditional dynamic magnetic units, they have a lighter and thinner diaphragm structure, which enables them to respond to audio signals faster and provide more accurate and clear sound quality.

[0038] Furthermore, if Figure 1 As shown, the flat unit 2 includes a planar diaphragm 21 with a planar voice coil 211 built in and an annular magnet, and the annular magnet is arranged in parallel with the planar diaphragm 21. It should be noted that a single-layer annular magnet or a double-layer annular magnet can be designed for the planar diaphragm 21, wherein the single-layer annular magnet refers to a layer of annular magnet arranged on the upper side or the lower side of the planar diaphragm 21, and the double-layer annular magnet refers to a layer of annular magnet arranged on both the upper side and the lower side of the planar diaphragm 21.

[0039] like Figure 1 As shown, in the first embodiment of the present application, the annular magnet includes an upper annular magnet 22 and a lower annular magnet 23 , and the planar diaphragm 21 is disposed between the upper annular magnet 22 and the lower annular magnet 23 .

[0040] The upper annular magnet 22 includes an upper annular inner magnet 221 and an upper annular outer magnet 222. The upper annular inner magnet 221 is located in the inner circle of the upper annular outer magnet 222. The lower annular magnet 23 includes a lower annular inner magnet 231 and a lower annular outer magnet 232. The lower annular inner magnet 231 is located in the inner circle of the lower annular outer magnet 232.

[0041] Furthermore, if Figure 2 As shown, the flat unit 2A includes a planar diaphragm 21A with an etched circuit built in, and a plurality of planar array magnet groups formed by a single magnet array distribution, and the planar array magnet group is arranged in parallel with the planar diaphragm 21A. It should be noted that a single-layer planar array magnet group or a double-layer planar array magnet group can be designed for the planar diaphragm 21A, wherein the single-layer planar array magnet group refers to a layer of planar array magnet group arranged on the upper side or the lower side of the planar diaphragm 21A, and the double-layer planar array magnet group refers to a layer of planar array magnet group arranged on both the upper side and the lower side of the planar diaphragm 21A.

[0042] like Figure 2 As shown, in the second embodiment of the present application, the planar array magnet group includes an upper planar array magnet group 22A and a lower planar array magnet group 23A, the planar diaphragm 21A is arranged between the upper planar array magnet group 22A and the lower planar array magnet group 23A, and the single magnet is in the shape of a long strip.

[0043] It should be noted that the difference between the second embodiment of the present application and the first embodiment of the present application lies in the different structures of the flat plate unit. The first embodiment is a ring-shaped magnet structure, and the second embodiment is an array-type magnet structure.

[0044] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
