Description

Technical Field

[0001] This utility model relates to the field of electroacoustic converter technology, and in particular to a centering support and a sound generating unit. Background Technology

[0002] As a commonly used electroacoustic transducer that converts electrical energy into sound energy, the sound-generating unit plays an indispensable role in the sound amplifier system.

[0003] As consumers demand higher performance from electroacoustic conversion devices, more and more electronic products are equipped with powder-filled sound modules. In powder-filled sound modules, the sound unit needs to have a metal mesh cover added to allow air to escape and to isolate sound-absorbing particles to prevent them from entering the sound unit.

[0004] In the prior art, the flange of the metal mesh cover is close to the inner edge of the outer fixing part of the centering support plate. The structural strength of the inner edge area of ​​the outer fixing part is not high. The area of ​​the cantilever part close to the outer fixing part can undergo a large degree of deformation. Therefore, when the sound unit is working, the cantilever part and the flange are prone to interference, which causes the sound unit to produce noise, or even the cantilever part to break.

[0029] 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.

[0030] Please refer to Figures 1 to 3 The centering support 4 includes an inner fixing part 41, a cantilever part 42 and an outer fixing part 43. The cantilever part 42 is connected to the inner fixing part 41. The inner edge of the outer fixing part 43 is connected to the cantilever part 42. A reinforcing part 431 protrudes from the outer fixing part 43 and is arranged along the inner edge of the outer fixing part 43.

[0031] As can be seen from the above description, the beneficial effects of this utility model are as follows: The centering support plate 4 has a novel structure, and the inner edge of the outer fixing part 43 is provided with a reinforcing part 431, which greatly enhances the structural strength of the inner edge area of ​​the outer fixing part 43. This helps to reduce the degree of deformation of the area of ​​the cantilever part 42 near the outer fixing part 43, thereby avoiding interference between the cantilever part 42 and the flange 51 when the sound unit is working, and thus ensuring the acoustic performance and structural stability of the sound unit.

[0032] Furthermore, the material of the reinforcing part 431 may be the same as or different from the material of the base material of the external fixing part 43.

[0033] As can be seen from the above description, the material of the reinforcement part 431 can be selected and set as needed.

[0034] Furthermore, the reinforcing part 431 and the external fixing part 43 are integrally formed into a single structure; or, the reinforcing part 431 is bonded to the external fixing part 43.

[0035] As can be seen from the above description, the connection method between the reinforcing part 431 and the external fixing part 43 can be selected as needed, which helps to enrich the diversity of the centering support 4.

[0036] Furthermore, a retaining wall 432 is also provided on the external fixing part 43, and a limiting groove 433 is formed between the retaining wall 432 and the reinforcing part 431.

[0037] As can be seen from the above description, the presence of the limiting groove 433 facilitates the positioning and installation of the metal mesh cover 5.

[0038] Furthermore, the external fixing part 43 is also provided with a welding area 434, which is located on the side of the retaining wall 432 away from the limiting groove 433, and the retaining wall 432 is an insulator.

[0039] As described above, the protruding baffle 432 can isolate the welding area 434. In the sound unit, the area of ​​the flange 51 of the metal mesh cover 5 near the outer fixing part 43 is located on the side of the baffle 432 away from the welding area 434. This ensures that when the centering support 4 is welded to the external structure, the solder will not come into contact with the flange 51 of the metal mesh cover 5, effectively avoiding poor welding and improving the production yield of the sound module or electronic product equipped with the sound unit.

[0040] Furthermore, the material of the retaining wall 432 may be the same as or different from the material of the base material of the external fixing part 43.

[0041] As can be seen from the above description, the material of the retaining wall 432 can be selected and set as needed.

[0042] Furthermore, the retaining wall 432 and the external fixing part 43 are integrally formed into a single structure; or, the retaining wall 432 is bonded to the external fixing part 43.

[0043] As can be seen from the above description, the connection method between the retaining wall 432 and the external fixing part 43 can be selected as needed, which helps to enrich the diversity of the centering support 4.

[0044] The sound-generating unit includes the aforementioned centering support 4.

[0045] Furthermore, it also includes a basin stand 1 and a metal mesh cover 5. The outer fixing part 43 is fixedly connected to the basin stand 1. The metal mesh cover 5 has a flange 51. The area of ​​the flange 51 near the outer fixing part 43 is located on the side of the reinforcing part 431 away from the cantilever part 42.

[0046] As can be seen from the above description, the centering support plate 4 in the sound unit will not have a conductive metal mesh cover 5 during welding.

[0047] Furthermore, the flange 51 is bonded to the reinforcing part 431.

[0048] As can be seen from the above description, the bonding of the flange 51 and the reinforcing part 431 can improve the overall structural stability of the sound unit.

The reinforcing part 431 is provided along the inner edge of the outer fixing part 43. The area of ​​the flange 51 near the outer fixing part 43 is located on the side of the reinforcing part 431 away from the cantilever part 42.

[0051] The protruding reinforcement 431 enhances the structural strength of the inner edge area of ​​the outer fixing part 43, thereby reducing the deformation of the cantilever part 42 near the outer fixing part 43 and thus reducing the risk of collision between the cantilever part 42 and the flange 51.

[0052] The material of the reinforcing part 431 may be the same as or different from the material of the base material of the external fixing part 43. When the material of the reinforcing part 431 is the same as the material of the base material of the external fixing part 43, the material of the reinforcing part 431 may be PI (polyimide), FR4 (epoxy fiberglass board), etc.

[0053] The reinforcing part 431 and the external fixing part 43 are integrally formed. For example, the reinforcing part 431 is formed simultaneously during the forming process of the centering support piece 4; or, the reinforcing part 431 is bonded to the external fixing part 43.

[0056] The material of the retaining wall 432 may be the same as or different from the material of the base material of the external fixing part 43. When the material of the retaining wall 432 is the same as the material of the base material of the external fixing part 43, the material of the retaining wall 432 may be PI (polyimide), FR4 (epoxy fiberglass board), etc.

[0057] The retaining wall 432 and the external fixing part 43 are integrally formed. For example, the retaining wall 432 is formed simultaneously during the forming process of the centering support piece 4; or, the retaining wall 432 is bonded to the external fixing part 43. In this case, the material of the retaining wall 432 can be insulating plastic, insulating rubber, etc.
