Description

Technical Field

[0001] The present application relates to the field of buttons, and in particular to a button device with adjustable sound status. Background Art

[0002] In the design of contemporary electronic devices, buttons play a vital role as a basic and intuitive interface for users to interact with the device. These button devices are usually designed to contain one or more movable button components, which move and trigger a switch mechanism when the user applies pressure through the finger. This mechanical action produces a physical click sound, which mainly comes from the collision between the button components and the rapid movement of components such as springs.

[0003] For example, the keys in a traditional computer keyboard are reset by a spring or rubber dome structure at the bottom, which rebounds quickly after being pressed, producing a specific sound. Similarly, the keys in remote controls and electronic game controllers also provide feedback through similar mechanical means. This audible feedback ensures that the user is aware that the operation has been performed without visual confirmation, enhancing the intuitiveness and sense of confirmation when using it.

[0004] Most traditional keypad technologies lack flexibility because they are fixed designs and do not provide options for adjusting the sound status, which fails to foresee the diversity of user needs and changes in scenarios. Specifically, in a home environment, especially at night or when children are sleeping, traditional audible keys may cause unnecessary noise interference, affecting the rest or activities of family members. At the same time, in public places such as libraries and conference rooms where quietness needs to be maintained, the keypad sound may be regarded as a factor that disrupts order, limiting the use of the device.

[0005] In summary, although the traditional key technology meets the basic interaction needs in terms of function, it has obvious deficiencies in user experience and environmental adaptability. Therefore, it is of great significance and value to develop a key device that allows users to adjust the sound state according to their needs and environmental conditions. Utility Model Content

[0006] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide an adjustable sound status button device, which allows the user to select an audible mode to obtain clear operational feedback or switch to a silent mode to adapt to a quiet working or resting environment.

[0007] To achieve the above-mentioned purpose, the present application discloses an adjustable sound state button device, comprising a base, a button body cooperating with the base, and a rubber component fixed on the mounting body, wherein the button body is installed in the base and has a resettable active stroke; the base has a stroke adjustment mechanism opposite to the button body, and the distance of the active stroke is adjusted via the stroke adjustment mechanism to control whether the rubber component and the base are in contact and cooperate within the active stroke.

[0008] Furthermore, the key signal triggering is realized between the key body and the base through the trigger component.

[0009] Preferably, the trigger assembly is a tactile trigger assembly, including a magnetic block installed in the guide column and a Hall device fixedly installed in the base and matched with the magnetic block to form a magnetic axis button.

[0010] Preferably, the trigger assembly is a photoelectric trigger assembly, comprising a pair of tubes installed in a base to form an optical axis button.

[0011] Furthermore, the base has a cavity for accommodating and installing the key body, the key body is installed in the cavity, and the key body at least partially extends upwardly out of the base.

[0012] Furthermore, the button body and the base are matched with each other through at least one spring member to achieve the resetting of the movable stroke.

[0013] Furthermore, the button body has a guide post in the stroke direction, the guide post faces the opening preset at the bottom of the base and is aligned with the stroke adjustment mechanism.

[0014] Further, the stroke adjustment mechanism is a switching block installed on the bottom surface of the base and capable of switching positions. The switching block has a deep step position and a shallow step position. The deep step position forms a low stroke position when matched with the bottom end of the guide column, and the shallow step position forms a high stroke position when matched with the bottom end of the guide column. The guide column is switched to the high stroke position or the low stroke position by sliding the switching block. The rubber component is installed on the key body and located in the base, and matches with the bottom surface of the base. A working stroke is formed between the rubber block and the bottom surface of the base. The height of the working stroke is greater than the high stroke position and less than the low stroke position. When the guide column matches with the low stroke position, the rubber block contacts and matches with the switching block earlier than the guide column to achieve silencing.

[0015] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0016] 1. Users can adjust the sound state of the buttons according to the current environment, from sound to silence or vice versa. This flexibility allows the same device to be used in different occasions without worrying about disturbing others or affecting one's concentration. The button device with adjustable sound state makes the product more humane and can attract user groups with specific needs for such functions, such as professionals who need to keep noise low in the office environment or night users at home who do not want to disturb their family. The addition of this innovative technology can significantly enhance the attractiveness and competitiveness of the product in the market. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figures 1 to 6 An exemplary structure for achieving the technical purpose of the present application is shown. Specifically, this embodiment describes a key device with adjustable sound state, which can adjust the key stroke and sound according to user needs and is suitable for electronic devices such as keyboards.

[0031] As shown in the figure, the device includes a base 1, a key body 2, a rubber part 3 and a switching block 4, and has the function of switching the key stroke, and can also realize the silent or audible state of the key operation.

[0032] Specifically, in this embodiment, the base 1 is the core bracket component of the adjustable sound state key device, and its design is responsible for the stability of the entire device and the correct installation of the components. The structure of the base 1 is usually made of high-strength plastic or metal to ensure durability and reliability for long-term use. ABS or polycarbonate (PC) is commonly used because of its good comprehensive properties, such as high strength, impact resistance, heat resistance and high cost-effectiveness. The base 1 has a hollow structure, which provides space for installing internal components such as the key body 2, the spring member 5, the trigger component, etc. The hollow design also helps to reduce the weight of the entire device.

[0033] In this embodiment, the bottom surface of the base 1 is designed with one or more openings for the extension of the guide column 6 in the key body 2 and the installation and sliding of the switching block 4. These openings are precisely aligned with the guide column 6 and the switching block 4 to ensure precise matching and smooth transition during operation. A sliding track is provided at the bottom of the base 1 to guide the movement of the switching block 4. This track ensures that the switching block can slide smoothly and accurately from one position to another to achieve the travel switching function.

[0034] It should be understood that the base 1 generally includes a preset screw hole or a snap-fit ​​structure, so that the key device can be easily installed at a proper position on a PCB substrate such as a keyboard, and can be easily disassembled when necessary.

[0035] Based on the above structure, as a further description of this embodiment, in this embodiment, the key body 2 is the core operating part of the key device, which is designed to respond to the user's pressing operation and transmit the operation signal through different mechanical structures. The key body 2 is usually made of hard materials such as plastic or metal, and is in the shape of a cylinder or a square column. It is fixed inside the base 1 by one or more spring members 7. These spring members 7 are sleeved on the key body 2 or located on the side of the key body 2, so that the key body 2 can move freely in the vertical direction and can automatically return to the initial position when released.

[0036] Furthermore, the key body 2 includes a guide column 6, which is a downwardly protruding structure, usually located at the center of the key body 2. The bottom of the guide column 6 is designed to be able to extend out of the opening on the bottom surface of the base 1, and interact with the switching block 4 to achieve stroke adjustment.

[0037] At the same time, the upper end of the key body 2 is designed to protrude from the base 1, which allows the user to easily reach and operate the key. In actual use, the top of the key body 2 is often matched with the key cap. The key cap has a logo and may include a non-slip surface or an ergonomic shape to enhance the user experience.

[0038] In order to realize the basic function of the key, a magnetic structure key is used in this embodiment, a magnetic block is installed in the key body 2, and a Hall effect device is installed in the relative position in the base 1. When the key is operated, the relative position of the magnetic block and the Hall device changes, generating an electrical signal, thereby realizing magnetic triggering.

[0039] In this embodiment, the function of the rubber part 3 is to adjust the sound and feel of the key operation, and to adjust the sound output of the key through the characteristics of its material and structure. The rubber part 3 is sleeved on the key body 2, connected to the key body 2 as a whole, and located inside the base 1. This arrangement allows the rubber part 3 to move synchronously with the guide column 6 when the key is pressed. The interaction between the rubber part 3 and the bottom surface of the base 1 defines an adjustable working stroke 8. The height of the working stroke 8 is fixed.

[0040] As a necessary component for switching the sound state, the switch block 4 is a mechanical component that can adjust the key stroke height, and the stroke can be quickly switched through user operation. Specifically, the switch block 3 is installed on the bottom surface of the base 1 and has the ability to slide on a preset track. This design allows the user to change the position of the switch block through a simple sliding operation to adjust the key stroke height.

[0041] More specifically, the switch block 3 is provided with a deep step position 9 and a shallow step position 10. The deep step position 9 allows the bottom of the guide post 6 to stop at a lower position, thereby increasing the total stroke of the key and forming a low stroke position 11. On the contrary, the shallow step position 10 provides a higher stop point, reduces the total stroke, and forms a high stroke position 12. The height of the working stroke 8 is designed to be greater than the high stroke position 12 and less than the low stroke position 11. This means that when the switch block is set to the high stroke position 12, the rubber part 3 will not contact the bottom surface of the base 1 before the guide post 6 of the key body 2 touches the bottom, thereby producing a more obvious click sound. When in the low stroke position 11, the working stroke 8 of the rubber part 3 allows it to contact the bottom surface of the base 1 before the guide post 6 touches the bottom, which not only avoids the sound of the guide post 6 due to contact, but also absorbs part of the impact force due to the material when in contact, reduces the sound, and achieves a silent effect.

[0042] It should be understood that, in the low stroke position, the bottom end of the guide post 6 cooperates with the deep step position 9 of the switching block 4 to form a longer stroke. In this setting, the rubber member 3 is designed to contact the bottom surface of the base 1 before the bottom end of the guide post 6 contacts the switching block 4. The purpose of this design is to enable the rubber member 3 to first absorb the kinetic energy generated by the rapid downward pressing of the key, reduce the impact, reduce the noise generated during the key operation, and achieve silence.

[0043] The position of the rubber part 3 on the key body and its material (usually highly elastic silicone or rubber) are key factors, which allow the rubber part to deform under pressure and absorb part of the kinetic energy, thereby reducing the impact sound. When the rubber part 3 first contacts the bottom surface of the base 1, it acts as a buffer, effectively blocking the sound of the guide column 6 hard contacting the bottom surface of the switch block 4, achieving a silent operation effect.

[0044] This key design ensures operational feedback, and the sound state of the key can be adjusted by simply sliding the switch block 4. This is not only suitable for occasions that require low noise in different environments, such as libraries or offices, but also meets the user's personalized needs for key feel and sound. By precisely controlling the working stroke of the rubber parts and guide columns, it is possible to provide silent or audible options while maintaining the quality of the user's input experience.

[0045] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
