Description

Technical Field

[0001] The present invention relates to the technical field of electronic equipment design, and in particular to a noise reduction component and electronic equipment. Background Art

[0002] Existing electronic devices will generate certain noises during operation. For example, laptop computers generate a lot of heat during operation. Therefore, a cooling fan is generally installed inside the shell of the laptop computer to dissipate the heat of the internal electronic components. The cooling fan will generate a lot of noise during the heat dissipation process.

[0003] Specific as Figure 1 As shown in the figure, the noise generated by the cooling fan of the laptop computer can be roughly divided into two paths according to the propagation path: the bottom shell propagation and the keyboard surface propagation. The noise propagating toward the bottom shell will lose a lot of sound energy after being absorbed and refracted by the desktop, and the proportion transmitted to the human ear is very small; the noise heard by the user is mainly caused by the transmission through the keyboard surface. Excessive noise will cause a poor user experience and make the user feel uncomfortable.

[0029] The invention discloses a noise reduction component and an electronic device, which are used to solve the technical problem that the existing electronic devices generate relatively large noise during operation.

[0030] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] See also Figures 2 to 4 , a noise reduction component provided by an embodiment of the present invention is used in an electronic device, wherein the electronic device comprises a housing 6, a noise source component 8 is installed inside the housing 6, a keyboard 7 is provided on the surface of the housing 6, the noise reduction component is installed inside the housing 6 and the noise reduction component is located between the keyboard 7 and the noise source component 8;

[0032] The noise reduction assembly includes a support plate 1, a support bar 3 and a film 2;

[0033] The support plate 1 is connected to the film 2 via the support bar 3 . The support plate 1 is used to support the keyboard 7 . The film 2 is located on a side of the support plate 1 facing the noise source component 8 .

[0034] In addition, the film 2 in this embodiment has a certain elasticity, and the film 2 needs to be arranged at a preset distance from the noise source component 8 .

[0035] It should be noted that the preset distance between the film 2 and the noise source component 8 can ensure that the film 2 has sufficient space to vibrate, so that it can convert the sound wave energy of the noise source component 8 into mechanical energy and internal energy as much as possible.

[0036] Through the above design, when the noise emitted by the noise source component 8 is transmitted to the film 2, the film 2 vibrates under the excitation of the high-variable pressure of the noise sound wave, and then bends and deforms, and the energy of the sound wave is converted into the mechanical energy and internal energy of the film 2, thereby reducing the sound energy of the noise to achieve a noise reduction effect, thereby giving the user a better experience. In addition, in the above design, while achieving a noise reduction effect, it will not affect the heat dissipation performance of the electronic device, ensuring that the user can use the electronic device normally.

[0037] Furthermore, in this embodiment, there are multiple support bars 3 , and the multiple support bars 3 are arranged at intervals between the film 2 and the support plate 1 .

[0038] It should be noted that this embodiment does not limit the number of support bars 3 , and designers can select a suitable number of support bars 3 according to the specific areas of the support plate 1 and the film 2 .

[0039] In addition, in this example, the support bars 3 are mainly provided to connect the film 2 and the support plate 1, and the support bars 3 arranged at intervals can provide the film 2 with sufficient vibration space.

[0040] Specifically, the first end of the support bar 3 in this embodiment is connected to the support plate 1, and the second end of the support bar 3 is connected to the film 2, wherein the second end of the support bar 3 is provided with a supporting protrusion 4 protruding toward the direction of the noise source component 8, and the supporting protrusion 4 protrudes from the film 2 and is used to abut against the noise source component 8 so that the film 2 is suspended on the noise source component 8.

[0041] It should be noted that, through the design of the above-mentioned support protrusion 4, sufficient space can be left between the lower surface of the film 2 and the noise source component 8 for the film 2 to vibrate. In addition, in order to facilitate the support protrusion 4 to protrude from the film 2, a through hole for the support protrusion 4 to protrude is pre-opened on the film 2 of this embodiment.

[0042] Furthermore, in another specific implementation of the present embodiment, the support strip 3 may adopt a structure in which the head and tail are connected, so as to form an annular closed structure (such as a rectangular structure, etc.), thereby closing the support plate 1, the support strip 3, and the film 2, ensuring that the air layer between the film 2 and the support plate 1 is a closed environment (closed but not a vacuum) to prevent air flow from affecting the sound absorption effect.

[0043] Furthermore, the support bar 3, the support protrusion 4 and the support plate 1 in this embodiment are an integrated structure.

[0044] It should be noted that the above design can ensure the structural integrity and stability of the noise reduction component and is easier to manufacture.

[0045] Furthermore, in this embodiment, a sound absorbing layer 5 is disposed on the surface of the support plate 1 facing the film 2 , and the sound absorbing layer 5 is spaced a preset distance from the film 2 .

[0046] It should be noted that, in this embodiment, when the noise generated by the noise source component 8 is between 20 and 2000 Hz, the above film 2 can absorb the noise very well; when the noise generated by the noise source component 8 exceeds 2000 Hz, the sound-absorbing layer 5 cooperates with the film 2 to absorb the high-frequency noise very well, thereby preventing the high-frequency noise from interfering with the user.

[0047] In addition, the design of the preset distance between the sound absorbing layer 5 and the film 2 can ensure that the film 2 has enough vibration space.

[0048] Furthermore, the sound absorbing layer 5 in this embodiment is preferably made of porous material, such as sound absorbing cotton.

[0049] Furthermore, the film 2 in this embodiment is preferably a graphene film.

[0050] It should be noted that the graphene film has elastic properties, which can absorb sound and reduce noise, and because graphene itself has excellent thermal conductivity, it can evenly distribute the temperature on the surface of the keyboard 7. Therefore, in this embodiment, the film 2 is preferably made of graphene material.

[0051] See also Figures 2 to 5 , an electronic device provided by an embodiment of the present invention comprises a housing 6, a noise source component 8 disposed in the housing 6, a keyboard 7 disposed on the surface of the housing 6, and the above-mentioned noise reduction component;

[0052] The noise reduction component is installed inside the housing 6 and is located between the keyboard 7 and the noise source component 8. The noise reduction component includes a support plate 1, a support bar 3 and a film 2;

[0053] The support plate 1 is connected to the film 2 via the support bar 3. The support plate 1 is attached to the surface of the keyboard 7 facing the noise source component 8 to support the keyboard 7. The film 2 is located on the side of the support plate 1 facing the noise source component 8 and is set at a preset distance from the noise source component 8.

[0054] Through the above design, when the noise emitted by the noise source component 8 is transmitted to the film 2, the film 2 vibrates under the excitation of the high-variable pressure of the noise sound wave, and then bends and deforms, and the energy of the sound wave is converted into the mechanical energy and internal energy of the film 2, thereby reducing the sound energy of the noise to achieve a noise reduction effect, thereby giving the user a better experience. In addition, in the above design, while achieving a noise reduction effect, it will not affect the heat dissipation performance of the electronic device, ensuring that the user can use the electronic device normally.

[0055] Furthermore, the first end of the support bar 3 in this embodiment is connected to the support plate 1, and the second end of the support bar 3 is connected to the film 2, wherein the second end of the support bar 3 is provided with a supporting protrusion 4 protruding toward the direction of the noise source component 8, and the supporting protrusion 4 protrudes from the film 2 and abuts against the noise source component 8 so that the film 2 is suspended on the noise source component 8.

[0056] It should be noted that, through the design of the above-mentioned supporting protrusion 4, sufficient space can be left between the lower surface of the film 2 and the noise source component 8 to allow the film 2 to vibrate.

[0057] Furthermore, the noise source component 8 in this embodiment includes a mainboard and at least one heat dissipation fan electrically connected to the mainboard.

[0058] It should be noted that the mainboard in this embodiment is mainly used to control the cooling fan. The noise generated by the cooling fan during operation is the noise source to be overcome in this embodiment.

[0059] Furthermore, the electronic device in this embodiment may be a notebook computer, etc., which is not limited in this embodiment.
