Description

Miniature high-pitch vibrating diaphragm

Technical Field

The utility model relates to a vibrating diaphragm, in particular to a miniature high-pitched vibrating diaphragm.

Background

The diaphragm, i.e. the sound membrane, also commonly called "cone", is the core component of the loudspeaker, which is the key of the loudspeaker to convert the level signal into the audio signal. When the loudspeaker inputs an electric signal, the electric signal drives the vibrating diaphragm to vibrate through the electromagnetic effect, the piezoelectric effect or the electrostatic effect principle, so that an audio signal is emitted.

Conventional diaphragms often require larger diaphragm sizes to achieve high frequencies, and for some miniature speakers, the diaphragms also have to be scaled down differently due to product volume limitations. In this way, the micro-speaker always has an unsatisfactory acoustic effect in the high-pitched part during sound production, and the problems of split vibration and the like often occur.

Disclosure of utility model

Based on this, it is necessary to provide a miniature high-pitched diaphragm in view of the shortcomings in the prior art.

A miniature high-pitch vibrating diaphragm comprises a copper ring, a diaphragm and a flat plate, wherein a central area, a corrugated area and an edge area are sequentially arranged on the diaphragm from inside to outside. The flat plate is attached to the central area of the top surface of the diaphragm, the copper ring is arranged on the edge area of the bottom surface of the diaphragm, and the corrugated area is positioned on the inner side of the copper ring and the outer side of the flat plate. The corrugated area is provided with a plurality of corrugated groups, the corrugated groups are radially distributed from the center to the outer side, each corrugated group comprises a plurality of corrugated strips which are sequentially arranged from inside to outside, and the cross sections of the corrugated strips are upwards-protruding arc-shaped.

Further, the corrugated strip comprises arc-shaped protruding portions and side faces arranged at two ends of the arc-shaped protruding portions.

Further, both sides of the corrugated strip face the middle inclined design.

Further, the corrugated sets are integrally arranged in a trapezoid shape from inside to outside, and the lengths of the corrugated strips are gradually widened from inside to outside.

Further, any corrugated strips on the membrane are arranged with equal width and equal height.

Further, the diaphragm is provided with a corrugated groove with a corresponding shape on the bottom surface of the corrugated set.

In summary, the micro high-pitched diaphragm has the beneficial effects that: the size of the vibrating diaphragm can be smaller than that of a conventional vibrating diaphragm by additionally arranging the radially arranged corrugated groups on the diaphragm of the vibrating diaphragm, and the amplitude of the vibrating diaphragm is smaller in the high-frequency vibration sounding process, so that the optimization of a high-frequency curve of the miniature vibrating diaphragm is realized; the arc-shaped raised corrugated strip structure has a certain supporting effect, can strengthen the stability of the vibrating diaphragm to a certain extent, and meanwhile, the tightness of the vibrating diaphragm at each position is more balanced, so that the dividing vibration phenomenon of the vibrating diaphragm is greatly weakened; the corrugated strips on the corrugated set can be designed into different shapes and sizes according to different frequency response requirements, and the acoustic curves of the vibrating diaphragm are further finely adjusted so as to be capable of matching with the hearing of different users; the utility model has strong practicability and has stronger popularization significance.

Detailed Description

In order to make the objects, technical solutions and advantages of the present utility model more apparent, the present utility model will be described in further detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 1 to 5, the present utility model provides a micro-high pitch diaphragm 100, which includes a copper ring 10, a diaphragm 20 and a flat plate 30, wherein the diaphragm 20 is sequentially provided with a central area 21, a corrugated area 22 and an edge area 23 from inside to outside. The flat plate 30 is attached to the central area 21 of the top surface of the membrane 20, the copper ring 10 is arranged on the edge area 23 of the bottom surface of the membrane 20, and the corrugated area 22 is positioned on the inner side of the copper ring 10 and the outer side of the flat plate 30.

The corrugated region 22 is provided with a plurality of corrugated groups 221, the plurality of corrugated groups 221 are radially distributed from the center to the outer direction, each corrugated group 221 comprises a plurality of corrugated strips 221a which are sequentially arranged from inside to outside, and the cross sections of the corrugated strips 221a are in an arc-shaped arrangement with upward protrusions. The annular corrugated area 22 formed by the plurality of corrugated groups 221 can effectively inhibit the vibration deformation amplitude of the vibrating diaphragm, and greatly optimize the vibration performance of the vibrating diaphragm, so that the vibrating diaphragm is more fidelity in a high-frequency sounding curve.

Specifically, in the present embodiment, the corrugated strip 221a includes an arc-shaped protrusion 221b and side surfaces 221c disposed at both ends of the arc-shaped protrusion 221 b. The two sides 221c of the corrugated strip 221a are inclined toward the middle. The structural strength of the vibrating diaphragm can be greatly improved by the design of the arc-shaped convex structure matched with the inclined side 221c, the overall tightness of the vibrating diaphragm is more balanced, and the vibration dividing phenomenon of the vibrating diaphragm is greatly weakened.

Specifically, in this embodiment, the corrugated set 221 is integrally formed in a trapezoid shape from inside to outside, and the lengths of the plurality of corrugated strips 221a are gradually widened from inside to outside. Any corrugated strips 221a on the membrane 20 are equally wide and equally high. The diaphragm 20 is provided with a corrugated groove 222 of a corresponding shape on the bottom surface of the corrugated set 221. It will be appreciated that in other embodiments, the length, width, height, dimension, angle, etc. of the corrugated strip 221a may be set to more different values. While the different shape and size of the corrugated strips 221a can make the acoustic curve of the diaphragm appear differently, so as to match the hearing feeling of different users.

In summary, the micro high-pitched diaphragm 100 of the present utility model has the following advantages: the size of the vibrating diaphragm can be smaller than that of a conventional vibrating diaphragm by additionally arranging the radially arranged corrugated groups 221 on the diaphragm 20 of the vibrating diaphragm, and the amplitude of the vibrating diaphragm is smaller in the high-frequency vibration sounding process, so that the optimization of a high-frequency curve of the miniature vibrating diaphragm is realized; the structure of the arc-shaped convex corrugated strip 221a has a certain supporting effect, so that the stability of the vibrating diaphragm can be enhanced to a certain extent, meanwhile, the tightness of the vibrating diaphragm at each position is more balanced, and the dividing vibration phenomenon of the vibrating diaphragm is greatly weakened; the corrugated strips 221a on the corrugated set 221 can be designed into different shapes and sizes according to different frequency response requirements, and the acoustic curve of the vibrating diaphragm is further finely adjusted so as to be capable of matching with the hearing of different users; the utility model has strong practicability and has stronger popularization significance.
