Abstract
Description
Technical Field
[0001] This utility model relates to the field of passive radiator technology, and in particular to a diaphragm structure for a passive radiator. Background Technology
[0002] Passive radiators, as important acoustic transducers, are widely used in loudspeaker systems, especially in products that require low-frequency extension and miniaturization. The core objective of the diaphragm structure of traditional passive radiators is to achieve maximum amplitude at a specific frequency. Therefore, the design focuses on the weight distribution of the diaphragm material, the compliance of the support system, and the reliability of the overall mechanical structure.
[0003] However, as consumer electronics products increasingly demand higher sound quality and visual experiences, traditional passive radiator designs have become increasingly limited. Their diaphragms, during reciprocating motion, offer a monotonous visual effect, failing to meet the high-end market's demand for a combination of sound and visual appeal. While existing technologies have attempted to improve visual effects by adding simple patterns or light guides to the diaphragm, these additional structures often affect the diaphragm's mass distribution and rigidity, easily leading to segmented vibrations and introducing unnecessary harmonic distortion, thus sacrificing fundamental acoustic performance. Utility Model Content
[0004] The main purpose of this invention is to provide a diaphragm structure for a passive radiator, which aims to ensure the structural stability of the diaphragm and improve its visual effect.
[0005] To achieve the above objectives, this utility model proposes a diaphragm structure for a passive radiator, comprising a diaphragm body and an abyss mirror assembly.
[0006] The diaphragm body includes, in a radial direction, a mounting assembly, a diaphragm assembly, and a fixing assembly. The mounting assembly has a through hole along the central axis. The through hole, the mounting assembly, the diaphragm assembly, and the fixing assembly are coaxially arranged.
[0007] The abyss mirror assembly includes, along the axial direction of the diaphragm body, a first lens for semi-transparency and semi-reflection, a support ring, and a second lens for reflecting a light source. The first lens is connected to one side of the mounting assembly and to the radiating surface of the diaphragm body. The support ring is connected to the other side of the mounting assembly and to the non-radiating surface of the diaphragm body. An abyss mirror cavity is formed between the first lens and the second lens. The through hole and the support ring surround the abyss mirror cavity.
[0008] In one embodiment of this application, the mounting component is connected to the inner periphery of the diaphragm assembly and has a first mounting portion protruding toward the first lens, the first mounting portion being connected to the diaphragm assembly; a partition groove is formed on the outer periphery of the first lens, the diaphragm assembly, and the first mounting portion.
[0009] In one embodiment of this application, the mounting assembly has a second mounting portion protruding toward the second lens, and a clearance cavity is formed between the second mounting portion, the mounting assembly, and the diaphragm assembly;
[0010] The support ring is connected to the second mounting part, and a clearance groove is formed between the second mounting part, the support ring, and the second lens.
[0011] In one embodiment of this application, the side of the first lens facing the abyss mirror cavity is provided with an electroplated layer for a light source that is semi-transparent and semi-reflective and is positioned on the abyss mirror assembly.
[0012] In one embodiment of this application, the second lens has a laser-engraved layer on one side facing the abyss cavity, and the other side is used to connect with the lamp structure and is coated with a filter layer.
[0013] By adopting the above technical solution, this utility model has the following advantages:
[0014] The diaphragm structure of this application mainly includes a diaphragm body and an abyss mirror assembly. The diaphragm body of this application has a through hole at its central axis, and an abyss mirror assembly is installed at the through hole. The abyss mirror assembly can strengthen the entire diaphragm body and make the entire diaphragm more aesthetically pleasing.
[0015] To ensure compatibility between the annular diaphragm body and the abyss mirror assembly, a mounting component is provided on the inner side of the diaphragm assembly, with through holes on the mounting component. A fixing component is provided on the outer periphery of the diaphragm assembly to facilitate installation in specific positions. The abyss mirror assembly itself includes a first lens, a support ring, and a second lens. The first lens is a semi-transparent, semi-reflective mirror, connected to the mounting component and located on the radiating surface of the diaphragm body. This first lens allows the user to face the abyss mirror surface for easy observation. The second lens is connected to the support ring and, through the support ring, to the mounting component. Both the second lens and the support ring are located on the non-radiating surface of the diaphragm body. The support ring separates the first and second lenses, increasing the reflection distance between them. This widens the spacing between the patterns formed by the abyss mirror assembly, resulting in better pattern formation. Furthermore, the support ring itself serves as a configuration for the above structure, facilitating the installation of the entire diaphragm structure. This structure improves the structural stability of the diaphragm and enhances its aesthetic appeal. Attached Figure Description

[0022] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0024] The following is in conjunction with the appendix Figures 1 to 3 The present invention will be further described below.
[0025] To achieve the above objectives, this utility model proposes a diaphragm structure for a passive radiator, comprising a diaphragm body 1 and an abyss mirror assembly 5.
[0026] The diaphragm body 1 includes, in a radial direction, a mounting component 2, a diaphragm component 3, and a fixing component 4. The mounting component 2 has a through hole 26 along the central axis. The through hole 26, the mounting component 2, the diaphragm component 3, and the fixing component 4 are coaxially arranged.
[0027] The abyss mirror assembly 5 includes, along the axial direction of the diaphragm body 1, a first lens 51 for semi-transparency and semi-reflection, a support ring 52, and a second lens 53 for reflecting a light source. The first lens 51 is connected to one side of the mounting assembly 2 and to the radiating surface of the diaphragm body 1. The support ring 52 is connected to the other side of the mounting assembly 2 and to the non-radiating surface of the diaphragm body 1. An abyss mirror cavity 6 is formed between the first lens 51 and the second lens 53. The through hole 26 and the support ring 52 surround the abyss mirror cavity 6.
[0028] The diaphragm structure of this application mainly includes a diaphragm body 1 and an abyss mirror assembly 5. The diaphragm body 1 of this application has a through hole 26 at its central axis, and the abyss mirror assembly 5 is installed at the through hole 26. The abyss mirror assembly 5 can strengthen the entire diaphragm body 1 and make the entire diaphragm more aesthetically pleasing.
[0029] To ensure the annular diaphragm body 1 can be compatible with the abyss mirror assembly 5, a mounting component 2 is provided on the inner side of the diaphragm assembly 3 of the diaphragm body 1. A through hole 26 is provided on the mounting component 2, and a fixing component 4 is provided on the outer periphery of the diaphragm assembly 3 to facilitate the installation of the diaphragm in a specific position. The abyss mirror assembly 5 itself includes a first lens 51, a support ring 52, and a second lens 53. The first lens 51 is a semi-transparent and semi-reflective mirror, which is connected to the mounting component 2 and located at the radiating surface of the diaphragm body 1. The first lens 51 installed here allows the user to face the mirror surface of the abyss mirror, facilitating observation. The second lens 53 is connected to... The second lens 53 and the support ring 52 are connected to the mounting assembly 2. The second lens 53 and the support ring 52 are located on the non-radiative surface of the diaphragm body 1. The support ring 52 can separate the first lens 51 and the second lens 53, thereby increasing the reflection distance between the first lens 51 and the second lens 53. This can increase the spacing between the patterns formed by the abyss mirror assembly 5, resulting in a better pattern effect. The support ring 52 itself can also be used as a configuration for the above structure, facilitating the installation of the entire diaphragm structure. The above structure can improve the structural stability of the diaphragm and give the diaphragm a better aesthetic function.
[0030] In one feasible embodiment, the fixing component 4 is connected to the outer ring of the diaphragm component 3 and is integrally formed with the diaphragm component 3. An undercut is provided on the outer ring of the fixing component 4 facing the non-radiating surface of the diaphragm body 1, which allows the diaphragm component 3 to be easily fixed to a structure such as a passive radiator. Meanwhile, the mounting component 2 can also be a ring structure and is integrally formed with the diaphragm component 3 and is connected to the inner side of the diaphragm component 3.
[0031] The specific mounting component 2 can have adhesive layers at both ends of the ring, which makes it easy to fix the first lens 51 and the support ring 52 onto the mounting component 2 and ensures the stability of the structure.
[0032] The diaphragm body 1 of this application is circular. The specific shape of the diaphragm body 1 can include various shapes such as arc, elliptical ring, and polygon. It is mainly used to make the diaphragm structure easy to install and meet the needs of different users.
[0033] In one embodiment of this application, the mounting component 2 is connected to the inner periphery of the diaphragm component 3 and has a first mounting portion 21 protruding toward the first lens 51. The first mounting portion 21 is connected to the diaphragm component 3. A partition groove 22 is formed on the outer periphery of the first lens 51, the diaphragm component 3, and the first mounting portion 21.
[0034] The mounting component 2 has a first mounting part 21 protruding from the radiating surface of the diaphragm body 1, which can also be called a first mounting protrusion. One end of the protrusion is connected to the through hole 26, and the other end is connected to the diaphragm assembly 3. It is used to mount the first lens 51. The first mounting part 21 is mainly connected to only part of the diaphragm assembly 3, so that a partition groove 22 is formed between the end of the first mounting part 21, the diaphragm assembly 3, and the first lens 51. The partition groove 22 can facilitate the connection of the first lens 51 by thickening the mounting component 2, and the partition groove 22 separates the first lens 51 from the diaphragm assembly 3, so that the first lens 51 will not be affected when the diaphragm is working normally, and the stability of the overall structure can be effectively guaranteed.
[0035] In one embodiment of this application, the mounting component 2 is provided with a second mounting portion 23 protruding toward the second lens 53, and a clearance cavity 24 is formed between the second mounting portion 23, the mounting component 2, and the diaphragm component 3;
[0036] The support ring 52 is connected to the second mounting part 23, and a clearance groove 25 is formed between the second mounting part 23, the support ring 52, and the second lens 53.
[0037] The second mounting part 23, like the first mounting part 21, thickens the mounting component 2. The connection between the mounting component and the diaphragm component 3 is relatively weak, allowing the mounting component 2 and the diaphragm component 3 to be separated. This facilitates the installation of the support ring 52. The clearance cavity 24 allows the entire diaphragm structure to be more stably fixed to the abyss mirror component 5. The clearance groove 25 allows the mounting component 2 to cover the support ring 52. Since the support ring 52 is made of metal for counterweight, the clearance groove 25 ensures that the diaphragm structure is not affected by the support ring 52 during operation. The light reflected by the support ring 52 can be blocked by the mounting component 2 as much as possible, ensuring the effectiveness of the abyss mirror.
[0038] In one embodiment of this application, the first lens 51 is provided with an electroplated layer on the side facing the abyss mirror cavity 6 for a light source that is semi-transparent and semi-reflective facing the abyss mirror assembly 5.
[0039] The first lens 51 is provided with an electroplated layer, which enables the first lens 51 to transmit light and form an abyss mirror effect under the action of an external light source. When the external light source is not working, the first lens 51 can form a reflective mirror effect, which can cover the internal structure of the abyss mirror assembly 5 and improve the aesthetic performance.
[0040] In one embodiment of this application, the second lens 53 has a laser-engraved layer on one side facing the abyss cavity 6, and the other side is used to connect with the lamp structure and is coated with a filter layer.
[0041] After the second lens 53 is installed on the passive radiator, it will be located inside the passive radiator and adjacent to the lamp structure facing it. To prevent users from seeing the lamp beads through the abyss mirror assembly 5 and thus damaging the aesthetics, the second lens 53 is provided with a filter layer facing the lamp structure. The filter layer is generally a white coating, which has a good shielding effect and can blur the lamp structure, so that the shape of the lamp beads cannot be seen through the second lens 53. Unlike the existing use of white one-piece molded plastic parts to replace the second lens 53 of this application, the second lens 53 of this application does not need to be molded and shaped. It can be directly cut from the glass substrate and sprayed with materials for rapid production. The structure of this application can effectively reduce costs.
[0042] The laser-engraved layer features a repeating pattern of the abyss mirror. It is formed by laser engraving and can scatter light. When part of the light from the lamp structure passes through the second lens 53, it illuminates the laser-engraved layer and forms the laser-engraved image. The light continues to pass through the abyss mirror cavity 6 and then partially passes through the electroplated layer of the first lens 51, and is partially reflected. As the number of reflections increases, the length of the path of the light passing through the first lens 51 in different times is different. The distance at which the user can see the laser-engraved image through the first lens 51 is different, which can form a stable abyss pattern and effectively improve the user experience.
