Abstract
Description
Technical Field
[0001] The present application relates to the field of acoustic technology, and in particular to a double-folded ring passive radiator and a speaker. Background Art
[0002] A passive radiator is a passive vibrating component, also known as a passive radiator. It typically consists of a diaphragm and a surround. Mounted to the speaker cabinet via its surround, the passive radiator forms a resonant system with the air inside. When the air inside the cabinet vibrates, the passive radiator vibrates with it, enhancing the low-frequency effect.
[0003] Traditional passive radiators have limited low-frequency performance. To improve performance, traditional designs require installing multiple passive radiators in different locations within the speaker cabinet, which increases costs and takes up a lot of space. Furthermore, in small, space-constrained speaker cabinets, increasing performance by adding multiple passive radiators is difficult. Summary of the Invention

[0012] In some optional embodiments, the cross-sectional shapes of the first upward convex section and the second upward convex section are both upward convex semicircular arcs, and the cross-sectional shapes of the first downward concave section and the second downward concave section are both downward concave semicircular arcs.
[0013] In some alternative embodiments, the lateral projections of the first convex segment and the first concave segment do not overlap, and the lateral projections of the second convex segment and the second concave segment do not overlap.
[0014] In some alternative embodiments, the radiator body is in a runway shape when viewed from above.
[0015] In some alternative embodiments, the radiator body includes: a frame, a diaphragm disposed within the frame, and a weight block connected to the diaphragm; wherein, the lateral projection of the first convex segment is higher than the frame, the lateral projection of the second concave segment is lower than the frame, and the lateral projections of the first concave segment and the second convex segment overlap with the frame.

[0032] A second folded ring 22, which is circumferentially connected to the outer lower edge of the radiator main body 10.
[0033] Here, the radiator main body 10 can be connected to the speaker box through at least one of its first folded ring 21 and second folded ring 22, and vibrates as the air in the speaker vibrates, thereby enhancing the low-frequency effect of the speaker.
[0034] In some alternative embodiments, the first surround 21 includes a plurality of first upper convex segments 211 and a plurality of first lower concave segments 212 that are sequentially spaced apart in the circumferential direction.

[0035] In some alternative embodiments, the first upper convex segment 211 and the second upper convex segment 221 overlap in the vertical direction, and the first lower concave segment 212 and the second lower concave segment 222 overlap in the vertical direction. In this way, the vibration balance can be better ensured.

[0036] In some alternative embodiments, the cross-sectional shapes of the first upper convex segment 211 and the second upper convex segment 221 can both be upwardly convex semi-circular arcs, or can also be triangular or other shapes, and the cross-sectional shapes of the first lower concave segment 212 and the second lower concave segment 222 can both be downwardly concave semi-circular arcs, or can also be triangular or other shapes.

[0039] In some alternative embodiments, the radiator body 10 includes: a frame, a diaphragm disposed within the frame, and a weight block connected to the diaphragm.
[0040] In some alternative embodiments, the lateral projection of the first upper convex segment 211 is higher than the frame, the lateral projection of the second lower concave segment 222 is lower than the frame, and the lateral projections of the first lower concave segment 212 and the second upper convex segment 221 overlap with the frame.
[0041] In some alternative embodiments, the diaphragm includes a first diaphragm and a second diaphragm: the first diaphragm is connected to the inner upper edge of the frame; the second diaphragm is connected to the inner lower edge of the frame; the weight block is located between the first diaphragm and the second diaphragm. By providing a double-layer diaphragm, a double vibration area can be achieved, and further combined with the weight block, the low-frequency effect can be better enhanced.
[0042] Reference Figures 5 to 6, embodiments of the present application also propose a speaker, which includes a double-folded ring passive radiator 100 as shown in FIGS. 1 to Figure 4 As shown. Here, the double-folded ring passive radiator 100 can be installed on the speaker cabinet 300. Exemplarily, an opening matching the shape of the double-folded ring passive radiator 100 is formed on the cabinet 300, and the double-folded ring passive radiator 100 is disposed at the opening and connected to the cabinet 300 through at least one of its first folded ring 21 and second folded ring 22.
