It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
Fig. 1 and 2 show a schematic structural diagram of a diaphragm 10 according to an embodiment of the present invention. As shown in fig. 1 and 2.
The vibrating diaphragm provided by the embodiment of the invention is rectangular, and comprises: the middle part 1 and the folded ring part 2 surrounding the outer periphery of the middle part 1.
The tuck-ring portion 2 comprises two opposite first edge portions and two opposite second edge portions, and an arc-shaped corner portion located between the first edge portions and the second edge portions, the arc-shaped corner portion and the end portions of the first edge portions and the end portions of the second edge portions connected thereto constituting corner regions. The corner region of the folded-over portion 2 is provided with a first pattern group 3 and a second pattern group 4.
The first pattern group 3 and the second pattern group 4 each comprise a plurality of single patterns 5.
The plurality of single patterns 5 of the first pattern group 3 are divergently arranged from the outer side to the inner side of the folded ring portion 2, and the plurality of single patterns 5 of the second pattern group 4 are divergently arranged from the inner side to the outer side of the folded ring portion 2.
The inner side of the folded ring portion 2 is the side connected to the intermediate portion 1, and the side opposite to the inner side of the folded ring portion 2, that is, the outer side of the folded ring portion 2.
When the diaphragm is operated in an operation mode higher than normal temperature, the vibration frequency of the outer side position of the junction of the corner region of the folded ring part 2 and the middle part 1 is large, so that the junction is easy to damage. When the diaphragm works in a normal-temperature working mode, the vibration frequency of the inner side position of the joint of the corner region of the folded ring part 2 and the middle part 1 is large, so that the joint is easy to damage.
Therefore, the technical scheme provided by the embodiment of the invention adopts a novel pattern design scheme, the adjacent first pattern group 3 and second pattern group 4 are arranged in the corner area of the folded ring part 2, the plurality of single patterns 5 of the first pattern group 3 are diverged from the outer side to the inner side of the folded ring part 2, and the plurality of single patterns 5 of the second pattern group 4 are diverged from the inner side to the outer side of the folded ring part 2. The combined action of the first pattern group 3 and the second pattern group 4 enables the vibrating diaphragm to meet the temperature requirements of different working modes, has an effective inhibiting effect on harmonic distortion, can improve the hearing quality and the acoustic performance of the electroacoustic transducer, and ensures that the loudspeaker has good performance under two working states. In addition, the vibrating diaphragm adopting the structure has high strength, and can effectively lighten the polarization phenomenon of products.
In the embodiment of the present invention, one possible way to implement the first pattern group 3 and the second pattern group 4 is to continue to refer to fig. 1, where the center lines 6 of the plurality of single patterns 5 of the first pattern group 3 intersect at a point outside the turnup portion 2. That is, the plurality of single patterns 5 of the first pattern group 3 are densely arranged at the outer side of the connection position of the corner region and the intermediate portion 1, and the connection strength thereof is enhanced.
Any two of the center lines 6 of the plurality of single patterns 5 of the second pattern group 4 of the same group intersect at a point inside the turnup portion 2. That is, the plurality of single patterns 5 of the second pattern group 4 are densely arranged at the inner side of the connection position of the corner region and the intermediate portion 1, and the connection strength thereof is enhanced.
Further, as shown in fig. 2, in order to more effectively suppress harmonic distortion, in the embodiment of the present invention, the first pattern group 3 is disposed near the first edge, and the lengths of the plurality of single patterns 5 of the first pattern group 3 gradually increase from the arc-shaped corner portion toward the first edge. The second pattern group 4 is disposed near the second side portion, and the lengths of the plurality of single patterns 5 of the second pattern group 4 become shorter gradually from the arc-shaped corner portion toward the second side portion.
In a specific implementation, the first side is a long side, and the second side is a short side. Taking the acquisition of the single patterns 5 in the first pattern group 3 as an example, the extending direction of the single patterns 5 of the first pattern group 3 can be acquired by the following method: taking a preset intersection point on the outer side of the ring folding part 2 as a center, and making a plurality of rays to the arc-shaped corner part of the ring folding part 2 according to a preset included angle and the number of single patterns 5, wherein each ray is the central line 6 of one single pattern 5. A single pattern 5 having a gradually longer length is formed from the arc-shaped corner portion toward the first side portion with the ray as the center line 6 across the annular folding portion 2. With continued reference to fig. 1, in order to strengthen the connection strength of the corner region of the turn-down portion 2 with the vibration position inside the junction of the intermediate portion 1, it is possible that the center lines 6 of the plurality of single patterns 5 of the second pattern group 4 are each tangential to the same circle inside the turn-down portion 2, which is close to the arc-shaped corner portion.
Further, among the center lines 6 of the plurality of single patterns 5 of the second pattern group 4, all the center lines 6 are equal to the tangential point chords of the tangential point lines of the same circle inside the turn-up portion 2.
In order to strengthen the connection strength of the corner region of the folded ring portion 2 and the vibration position outside the connection of the intermediate portion 1, one possible way is that the included angles of all two adjacent center lines 6 are equal among the center lines 6 of the plurality of single patterns 5 of the first pattern group 3.
In the embodiment of the present invention, the first pattern group 3 and the second pattern group 4 may be set on the folded ring portion 2 in different setting modes according to different application environments and requirements. For example, including but not limited to the following:
