Description
TECHNICAL FIELD
[0001] The utility model relates to a vibrating diaphragm, especially to a headphone vibrating diaphragm with positive and negative waveform arc surface characteristics. BACKGROUND
[0002] The vibrating diaphragm, also commonly known as a cone, is a core component of a loudspeaker and is a key to converting an electrical signal into an audio signal. When an electrical signal is input into the loudspeaker, the electrical signal drives the vibrating diaphragm to vibrate through electromagnetic effect, piezoelectric effect or electrostatic effect, thereby emitting an audio signal.
[0003] Conventional vibrating diaphragms are mostly designed in combination of a one-way folded ring and a dome, which are usually used in loudspeaker units to improve the clarity and directivity of sound. However, this one-way folded ring design has several problems. Firstly, the rigidity of the folded ring is insufficient, which is prone to deformation under working vibration, affecting the sound quality and stability of the loudspeaker. Secondly, the intensity of the middle and low frequencies is insufficient, which makes the sound performance unbalanced, with the high frequency part being relatively prominent, resulting in a high-frequency valley and a folded phenomenon in the SPL curve. Thirdly, the diaphragm is prone to segmented vibration under high-power vibration, resulting in distortion of the middle and low frequencies and affecting the purity of the sound quality. SUMMARY
[0004] Therefore, it is necessary to provide a headphone vibrating diaphragm with positive and negative waveform arc surface characteristics to solve the above problems.
[0005] A headphone vibrating diaphragm with positive and negative waveform arc surface characteristics comprises a dome, a vibrating diaphragm body and a folded ring arranged in sequence from inside to outside. The vibrating diaphragm body is annularly connected to the outer edge of the dome, and the folded ring is annularly connected to the outer edge of the vibrating diaphragm body. The folded ring comprises a plurality of convex peak segments and a plurality of concave valley segments, which are uniformly and alternately spliced to form the folded ring. The highest height of the convex peak segment is greater than the height of the outer edge of the vibrating diaphragm body, and the lowest height of the concave valley segment is less than the height of the outer edge of the vibrating diaphragm body.
[0006] Further, the cross section of the convex peak segment along its extension direction is designed in a wave shape, which comprises a plurality of outer convex parts and a plurality of inner concave parts arranged in sequence and alternately.
[0007] Further, the outer convex part and the inner concave part are both higher than the top surface of the vibrating diaphragm body.
[0008] Further, the concave valley segment is designed in a boat-shaped structure, with the bottom being designed in a middle section level and the two ends being designed in a gradually upward curved and warped manner.
[0009] Further, one end of the convex peak segment is designed in a "V"-shaped outward convex structure, and the other end of the concave valley segment is designed in a "V"-shaped inward concave structure. The "V"-shaped outward convex end of the convex peak segment and the "V"-shaped inward concave end of the corresponding concave valley segment are smoothly spliced.
[0010] Further, the earphone diaphragm with positive and negative wave-shaped curved surface features further comprises a connecting portion, which is in a horizontal ring structure design and integrally connected with the spherical top and the diaphragm body on two sides.
[0011] Further, the earphone diaphragm with positive and negative wave-shaped curved surface features further comprises a positioning ring, which is integrally connected to the outer edge of the folded ring in a horizontal ring structure.
[0012] Further, the spherical top is in a conical shape.
[0013] Further, the convex peak segments and the concave valley segments are each provided with four, and the four convex peak segments and the concave valley segments are uniformly staggered and spliced to form the folded ring.
[0014] In summary, the earphone diaphragm with positive and negative wave-shaped curved surface features has the beneficial effects that: the diaphragm with the folded ring with positive and negative wave-shaped peak and valley structure can provide stable support for the operation of the loudspeaker, and also increases the rigidity and ductility of the folded ring, effectively improving the clarity of the sound; the positive and negative concave-convex structure design greatly improves the support strength of the suspension edge structure, makes the middle-high frequency valley, the turning peak valley gentle, and the high frequency extension, which helps to improve the performance and sound quality of the loudspeaker; in the high-power state of the loudspeaker, the positive and negative curved surface feature design of the diaphragm can also effectively avoid the large distortion caused by the divided vibration; the utility model has strong practicability and strong popularization significance.

[0019] In order to make the purpose, technical scheme and advantages of the utility model more clear and explicit, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.
[0020] As Figs. 1 to 4As shown, the utility model provides a earphone diaphragm 100 with positive and negative waveform camber characteristics, it includes the spherical top 10, diaphragm main part 20 and the ring 30 that are sequentially arranged from inside to outside. It needs to be noticed, because simple line structure schematic diagram cannot fully embody the structure design of the utility model, therefore in the description accompanying drawing, the entity structure schematic diagram of the utility model is added.
[0021] The spherical top 10 is conically arranged, and the diaphragm main part 20 is annularly connected to the outer edge of the spherical top 10. The ring 30 is annularly connected to the outer edge of the diaphragm main part 20, and the ring 30 includes four convex peak segments 31 and four concave valley segments 32. The four convex peak segments 31 and the four concave valley segments 32 are uniformly and alternately spliced to form the ring 30. The maximum height of the convex peak segment 31 is greater than the height of the outer edge of the diaphragm main part 20, and the minimum height of the concave valley segment 32 is less than the height of the outer edge of the diaphragm main part 20.
[0022] The ring 30 with positive and negative waveform camber characteristics has higher structural strength compared with the conventional ring 30 with one-way convex arc or concave arc structure. The ring 30 not only provides stable support for the speaker, but also effectively avoids large distortion caused by segmented vibration in the high-power state of the loudspeaker. In addition, the structure of the positive and negative waveform camber can further optimize the frequency response curve, especially for the extension of high frequency.
[0023] Specifically, in the embodiment, the cross section of the convex peak segment 31 along the extension direction thereof is designed in a wave shape, which includes a plurality of outer convex portions 311 and a plurality of inner concave portions 312 arranged alternately. The outer convex portions 311 and the inner concave portions 312 are both higher than the top surface of the diaphragm main part 20. The concave valley segment 32 is designed in a boat shape, and the bottom thereof is designed in a middle section horizontally and two ends gradually upwardly curved. The wave-shaped convex peak segment 31 can further improve the rigidity and ductility of the ring 30, and greatly improve the sound clarity. The curved boat-shaped concave valley segment 32 further improves the smoothness of the ring 30, and enriches the sound quality of the diaphragm.
[0024] Specifically, in the embodiment, one end of the convex peak segment 31 is designed in a "V"-shaped outer convex structure, and one end of the concave valley segment 32 is designed in a "V"-shaped inner concave structure. The "V"-shaped outer convex end of the convex peak segment 31 is smoothly spliced with the "V"-shaped inner concave end of the corresponding concave valley segment 32. The asymmetric smooth splicing structure design can further reduce the segmented vibration phenomenon and avoid the problem of large distortion of the loudspeaker sound.
[0025] The earphone diaphragm 100 with positive and negative waveform arc surface characteristics further comprises a connecting portion 40, which is designed in a horizontal ring structure and integrally connected with the spherical top 10 and the diaphragm body 20 on both sides.
[0026] In conclusion, the earphone diaphragm 100 with positive and negative waveform arc surface characteristics has the following advantages: the diaphragm with the positive and negative waveform peak and valley structure folding ring 30 can provide stable support for the speaker, and the rigidity and ductility of the folding ring 30 are increased, so that the sound clarity is effectively improved; the positive and negative concave-convex structure design greatly improves the support strength of the suspension edge structure, so that the middle-high frequency valley, turning peak, peak valley is gentle, and the high frequency is extended, which helps to improve the performance and sound quality of the speaker; in the high-power state of the speaker, the positive and negative arc surface characteristic design of the diaphragm can effectively avoid the large distortion caused by the divided vibration; the utility model has strong practicability and strong popularization significance.
