Detailed implementation manners

[0025] To make the objectives, features, and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present disclosure.

[0026] With the wide application of electronic devices, the research and development directions of the performance of each component or structural member in the electronic device are becoming more and more extensive. According to different functions, different functional structures are included in the electronic device. On the premise that the electronic device needs to emit sound, the electronic device generally includes a speaker. As a sound - emitting component, the speaker is generally fixedly installed at a corresponding position in the electronic device. However, the existing methods for assembling the speaker basically rely on screw locking, rubber parts, and adhesive tape attachment to be fixed on the circuit board. Such a method requires the following three components: adhesive tape, rubber parts, and screws. In this way, the fixed material costs of the three components are relatively high and it is labor - consuming.

[0027] To alleviate the above problems, embodiments of the present disclosure provide a speaker fixing module, which can apply a small number of structural components, reduce the assembly process, and perform rapid assembly and disassembly of the speaker module. It should be noted that the first direction is the length direction of the speaker module, the second direction is the width direction of the speaker module, and the third direction is the height direction of the speaker module.

[0028] Referring to Figures 1-5 , embodiments of the present disclosure provide a speaker fixing module 001, including: a fixing member 30, which can be an original structure on the electronic device or a new structure matching the installation space of the speaker 20. Specifically, the fixing member 30 includes a first fixing plate 31, a first fixing member 32 located on the first fixing plate 31, and a second fixing plate 33 located above the first fixing plate 31. Among them, there are two first fixing members 32, and the two first fixing members 32 are oppositely arranged on the surface of the first fixing plate 31, and an installation space for assembling the speaker 20 module is reserved between the two first fixing members 32. For the convenience of rapid assembly and without introducing other assembly processes, the speaker 20 can be elastically pressed between the two first fixing members 32 along the first direction X, and the speaker 20 can be elastically pressed between the first fixing plate 31 and the second fixing plate 33 along the third direction Z. Taking the electronic device as a laptop computer as an example, considering the actual installation scenario of the speaker 20, the first fixing plate 31 and the second fixing plate 33 can be one of the upper shell or the lower shell of the electronic device housing respectively.

[0029] In this way, during the assembly and fixing process of the speaker 20, it is only necessary to assemble the speaker 20 module into the installation space between the two first fixing members 32, without other auxiliary structures with a fixing function. With as few assembly components as possible, the production cost can be saved to the greatest extent.

[0030] Specifically, embodiments of the present disclosure provide a speaker fixing module 001, further including: a damping member 10, which can be wrapped and installed on both sides of the speaker 20 cavity, and the damping member 10 is used to absorb the vibration potential energy of the speaker 20; the aforementioned fixing member 30 has a first installation position, and the first installation position is the installation space between the two first fixing members 32 mentioned above. The damping member 10 is installed in the first installation position in a point contact manner, so that the speaker 20 is installed at a preset position in an immovable manner along its circumferential direction. In this way, the speaker 20 can be assembled at the preset position of the electronic device through the damping member 10. By utilizing the elastic low-pressure performance between the damping member 10 and the first fixing member 32, the first fixing plate 31, and the second fixing plate 33, the speaker 20 can be stably assembled in the first installation position.

[0031] Considering the stable limit of the speaker 20 at the first installation position, in the embodiments of the present disclosure, the damping member 10 wraps around one side of the cavity of the speaker 20 in the first direction X, and the fixing member 30 limits and installs the damping member 10 and the speaker 20 at a preset position in the first direction X, the second direction Y, and the third direction Z respectively. In this way, six degrees of freedom can be restricted circumferentially of the speaker 20 to prevent the speaker 20 from shifting during the assembly state of the electronic device.

[0032] Specifically, according to the installation scenario of the speaker 20 in the embodiments of the present disclosure, the first fixing member 32 and the damping member 10 are used to limit the non-rotatable installation of the speaker 20 at a preset position along the first direction X and the second direction Y; the second fixing plate 33, the first fixing plate 31, and the damping member 10 are used to limit the non-movable installation of the speaker 20 at a preset position along the third direction Z.

[0033] Exemplarily, there are two first fixing members 32, and the two first fixing members 32 are isolated and oppositely arranged on the surface of the first fixing plate 31. Each first fixing member 32 has a fixing card slot 321, and the openings of the two fixing card slots 321 are oppositely arranged. Each fixing card slot 321 is used to accommodate a damping member 10, and a first installation position is reserved between the two oppositely arranged fixing card slots 321. Exemplarily, the fixing card slot 321 runs through the first fixing member 32 along the third direction Z; alternatively, the fixing card slot 321 is formed in the first fixing member 32 along the third direction Z and forms an inner bottom surface in the first fixing member 32, and the damping member 10 can be clamped between the inner bottom surface and the second fixing plate 33, that is, the damping member 10 is limited at a preset position along the third direction Z. The function of the inner bottom surface relative to the damping member 10 is the same as that of the surface of the first fixing plate 31 relative to the damping member 10.

[0034] Taking the scheme that the damping member 10 is installed between the first fixing plate 31 and the second fixing plate 33 in a point-contact manner along the third direction Z as an example. In the embodiments of the present disclosure, the fixing card slot 321 includes a first surface 3211 and a second surface 3212 arranged oppositely, and a third surface 3213 is between the first surface 3211 and the second surface 3212. The two oppositely arranged third surfaces 3213 of the two first fixing members 32 are used to define the installation position of each damping member 10 along the first direction X, and the first surface 3211 and the second surface 3212 are used to define the installation position of each damping member 10 along the second direction Y. In this way, the first fixing member 32 is configured as a C-shaped member structure, with a simple forming method, convenient for production, and at the same time, facilitating the assembly of the speaker 20 module and the damping member 10 in the embodiments of the present disclosure.

[0035] Based on the specific structural composition of the fixing member 30 as above, the damping member 10 is assembled with the first surface 3211, the second surface 3212, the third surface 3213, the first fixing plate 31, and the second fixing plate 33 in a point-contact manner.

[0036] Exemplarily, the vibration damping member 10 is an elastic housing. One side of the elastic housing has an opening 11, and one side of the cavity of the speaker 20 is wrapped by the elastic housing through the opening 11. In this way, the vibration damping member 10 and the speaker 20 are pre-assembled into an integral structure and are jointly installed in the installation space of the first installation position between the two first fixing members 32. Based on the point contact assembly of the third surfaces 3213 on both sides, the speaker 20 and the vibration damping member 10 can be pre-stably positioned. Then, based on the buckling relationship between the first fixing plate 31 and the second fixing plate 33, the vibration damping member 10 can be elastically pressed between the first fixing plate 31 and the second fixing plate 33 along the third direction Z. In this way, under the combined limiting action of the first fixing member 32, the first fixing plate 31 and the second fixing plate 33, the speaker 20 with the vibration damping member 10 can be stably limited and installed at the preset position. The assembly steps are few, and the auxiliary assembly can be realized only through the vibration damping member 10, which can reduce the fixed installation cost of the speaker 20 module.

[0037] Exemplarily, the outer periphery of the elastic housing has elastic protrusions 12, and the elastic housing is assembled with each installation surface in a point contact manner through the elastic protrusions 12. Here, the installation surfaces are respectively the first surface 3211, the second surface 3212, the third surface 3213 of the fixed card slot 321 of the first fixing member 32, the first fixing plate 31 (or the inner bottom surface), and the second fixing plate 33.

[0038] Exemplarily, the elastic housing is integrally formed by using an elastic material as a whole, or the elastic housing is a combined structure with elastic protrusions 12 formed on the outer periphery of the main body through existing processing techniques. Or, the elastic protrusions 12 can be constructed as an elastic main body structure, or the elastic protrusions 12 can also adopt standard structural bodies with elastic contraction properties such as springs or elastic arms.

[0039] In addition, the embodiment of the present disclosure also provides an electronic device, including the above-mentioned speaker fixing module 001, wherein the fixing member 30 is formed on the electronic device housing, and the electronic device housing has a sound transmission hole position 331 corresponding to the sound emitting position of the speaker 20, so that the speaker 20 module with the vibration damping member 10 can transmit sound to the external environment of the electronic device.

[0040] Exemplarily, the sound transmission hole 331 is configured as a porous structure densely formed within a preset surface area position.

[0041] In summary, for the speaker fixing module 001 and the electronic device provided by the embodiments of the present disclosure, the damping member 10 is fixed on the speaker and assembled into the pre-reserved mechanism fixing slot 321, which plays a role in fixing the speaker. Moreover, the damping member 10 can absorb the vibration of the speaker and effectively reduce the vibration transmitted from the speaker to the whole machine. Specifically, the damping member 10 is sleeved on both sides of the speaker 20 module through the position of its unique opening 11. According to different actual installation scenarios, the damping member 10 can be sleeved around both ends of the speaker 20 cavity. The speaker 20 can be understood as a horn, and the component for generating sound in the horn is the tympanic membrane. The tympanic membrane can transmit the vibration potential energy to the elastic protrusions 12 of the damping member 10 through the speaker 20 cavity. The damping member 10 can be used to absorb the vibration potential energy, further ensuring the stable positioning of the speaker 20 and preventing displacement. In addition, the damping member 10 can be made of silicone material, with a hollow interior. A structure with one end closed can be sleeved on the features at the end of the horn module, and the elastic protrusions 12 are in contact or abutment with the surrounding structural members. Through the point contact between the elastic protrusions 12 and the surrounding structural members, the vibration of the horn is fully absorbed, preventing the vibration from being transmitted to the surrounding structures for fixing the speaker 20. The shape, density, and material of the elastic protrusions 12 can adjust the compliance and damping of the damping system to adapt to horn systems with different vibration forces and vibration masses.

For example, the steps described in the present disclosure can be executed in parallel, sequentially, or in a different order, as long as the desired results of the technical solutions disclosed in the present disclosure can be achieved.

Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present disclosure, and all should be covered by the protection scope of the present disclosure.
