Description

Technical Field

[0001] This utility model relates to the field of electroacoustic converter technology, and in particular to a diaphragm assembly. Background Technology

[0002] As a commonly used electroacoustic transducer that converts electrical energy into sound energy, the sound generator plays an indispensable role in the sound amplifier system, and the diaphragm assembly is an essential component of the sound generator.

[0003] To reduce the weight of the diaphragm assembly, the industry often chooses to create a window in the central area of ​​the diaphragm assembly, which is then sealed with a dome. The dome also increases the rigidity of the diaphragm assembly. However, in actual production, the material generated from hollowing out the central area of ​​the diaphragm assembly is considered waste, undoubtedly resulting in a waste of raw materials and increased manufacturing costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a diaphragm assembly that can reduce manufacturing costs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a diaphragm assembly, comprising:

[0006] The main body includes an inner fixing part, a deformable part and an outer fixing part connected sequentially from the inside to the outside. The center of the inner fixing part has several parts to be cut, and each part to be cut has a folded ring part.

[0007] Furthermore, when there are multiple portions to be cut, the multiple portions to be cut are arranged concentrically.

[0008] Furthermore, when there are multiple portions to be cut, the multiple portions to be cut are arranged in at least one row.

[0009] Furthermore, the portion to be cut includes an inner mounting portion, the folded ring portion, and an outer mounting portion connected sequentially from the inside out.

[0010] Furthermore, the inner mounting part is provided with a dome.

[0011] Furthermore, the outer mounting portion is provided with a front cover, the edge of which is aligned with the edge of the portion to be cut to which the front cover is connected.

[0012] Furthermore, the material of the main body is PEEE, TPEE, or rubber.

[0013] Furthermore, the inner fixing part is provided with a center sticker, which is close to the deformable part and is arranged in a circle.

[0014] Furthermore, a fixing ring is provided along the edge of the outer fixing part.

[0015] Furthermore, the retaining ring is made of metal, plastic, or rubber.

[0016] The beneficial effects of this invention are as follows: The novel structure of this diaphragm assembly transforms the area that would otherwise need to be hollowed out into a cutting section. Each cutting section can form a diaphragm for manufacturing a smaller sound-generating unit, thus making fuller use of the main material, reducing material waste, and lowering manufacturing costs. In other words, after subsequent cutting, this diaphragm assembly can form at least two diaphragms for sound-generating units of different sizes. Attached Figure Description

[0027] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0028] Please refer to Figures 1 to 4 A diaphragm assembly, comprising:

[0029] The main body includes an inner fixing part 1, a deformable part 2 and an outer fixing part 3 connected sequentially from the inside to the outside. The center of the inner fixing part 1 has several parts to be cut 4, and each part to be cut 4 has a folded ring part 42.

[0030] As can be seen from the above description, the beneficial effects of this utility model are as follows: the diaphragm assembly has a novel structure, which makes the area that originally needed to be hollowed out become the cutting part 4, and each cutting part 4 can form a diaphragm for manufacturing a smaller sound unit, thereby making fuller use of the main material, reducing raw material waste, and reducing manufacturing costs.

[0031] Furthermore, when there are multiple portions 4 to be cut, the multiple portions 4 to be cut are arranged concentrically.

[0032] Furthermore, when there are multiple portions 4 to be cut, the multiple portions 4 to be cut are arranged in at least one row.

[0033] As can be seen from the above description, when there are multiple parts 4 to be cut, the arrangement of these multiple parts 4 on the inner fixing part 1 can be selected according to actual needs.

[0034] Furthermore, the part to be cut 4 includes an inner mounting part 41, the folded ring part 42, and an outer mounting part 43 connected sequentially from the inside to the outside.

[0035] Furthermore, the inner mounting part 41 is provided with a dome 44.

[0036] As can be seen from the above description, the setting of the dome 44 can improve the rigidity of the diaphragm forming the small-sized sound unit, thereby improving the sound performance.

[0037] Furthermore, the outer mounting part 43 is provided with a front cover 45, the edge of the front cover 45 being aligned with the edge of the part 4 to be cut to which the front cover 45 is connected.

[0038] As can be seen from the above description, the presence of the front cover 45 allows for more precise cutting of the part 4 to be cut, and facilitates the subsequent assembly of small-sized sound units.

[0039] Furthermore, the material of the main body is PEEE, TPEE, or rubber.

[0040] As can be seen from the above description, the material of the main body can be selected and set according to actual needs.

[0041] Furthermore, the inner fixing part 1 is provided with a center sticker, which is close to the deformable part 2 and is arranged in a circle.

[0042] As described above, the presence of a center patch can improve the rigidity of the diaphragm of a large-sized sound unit, thereby improving its sound performance.

[0043] Furthermore, a fixing ring 5 is provided on the edge of the outer fixing part 3.

[0044] As can be seen from the above description, the presence of the fixing ring 5 facilitates the assembly of the diaphragm of the subsequent large-size sound unit.

[0045] Furthermore, the fixing ring 5 is made of metal, plastic, or rubber.

[0046] As can be seen from the above description, there are various materials available for the fixing ring 5, which helps to enrich the diversity of diaphragms in large-size sound units.

[0047] Please refer to Figure 1 and Figure 2 The first embodiment of this utility model is as follows: a diaphragm assembly includes a main body, the main body including an inner fixing part 1, a deformation part 2 and an outer fixing part 3 connected sequentially from the inside to the outside, the center of the inner fixing part 1 has a plurality of cut-out parts 4, each cut-out part 4 has a folded ring part 42, and the material of the main body is PEEK (polyether ether ketone), TPEE (thermoplastic polyester elastomer), rubber or other materials.

[0048] It is easy to understand that after the diaphragm assembly is cut in the later stage, each of the cut-out parts 4 becomes a new diaphragm of a smaller size. It can be seen that this diaphragm assembly also has the advantage of saving storage and transportation costs. Specifically, storing / transporting one of this diaphragm assembly is equivalent to storing / transporting multiple diaphragms of different sizes at the same time.

[0049] In one or more embodiments, the portion to be cut 4 includes an inner mounting portion 41, the folded ring portion 42, and an outer mounting portion 43 connected sequentially from the inside to the outside.

[0050] When there are multiple portions 4 to be cut, the multiple portions 4 to be cut are arranged concentrically. Alternatively, when there are multiple portions 4 to be cut, the multiple portions 4 to be cut are arranged in at least one row.

[0051] In this embodiment, the number of the portion 4 to be cut is one. Figure 1 and Figure 2 The area defined by the dotted line is the part to be cut 4. Later, the main body is cut along the dotted line to obtain two diaphragms of different sizes. These two diaphragms are suitable for two sound generating units of different sizes.

[0052] Optionally, the inner fixing part 1 is provided with a center sticker, which is close to the deformable part 2 and is arranged in a circle.

[0053] In some embodiments, the outer fixing part 3 is provided with a fixing ring 5 along its edge, and the fixing ring 5 is made of metal, plastic, rubber or other materials.

[0054] Please refer to Figure 3 and Figure 4The second embodiment of this utility model is a parallel technical solution to the first embodiment. The difference between the two embodiments is that the inner mounting part 41 of the part to be cut 4 is provided with a dome 44, thereby improving the rigidity of the part to be cut 4.

[0055] Optionally, a front cover 45 is provided on the outer mounting part 43 of the part to be cut 4. It is easy to understand that the front cover 45 is generally in the shape of a ring frame. The edge of the front cover 45 is aligned with the edge of the part to be cut 4 to which the front cover 45 is connected. In this way, during the subsequent cutting, cutting can be carried out along the edge of the front cover 45, which helps to ensure cutting accuracy. At the same time, it facilitates the assembly of the small-sized diaphragm formed by the part to be cut 4 and other components of the small-sized sound unit.

[0056] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
