Technical Field

[0001] The utility model relates to the technical field of computers, in particular to a keyboard. Background Art

[0002] With the continuous development of science and technology, people's requirements for the functions and experience of electronic devices are getting higher and higher. As a common device for inputting instructions and data to operate equipment, keyboards have become an indispensable part of people's daily work and entertainment.

[0003] However, the traditional keyboard can only provide text input function, and its function is single, which cannot meet people's demand for multi-functional devices. Specifically, in order to increase the sound structure, an external speaker is added, so in order to facilitate carrying, the size of the external speaker is reduced. However, since the external speaker is an independent unit, if the user forgets the external speaker when carrying the keyboard, it will cause trouble to the user. At the same time, the external speaker will also occupy the already limited desktop space, which is not convenient for users to use. Utility Model Content

[0004] In view of this, the utility model provides a keyboard to solve the problem that when adding sound effects to the existing keyboard, an independent sound system needs to be added, which is inconvenient for users to use.

[0005] The utility model provides a keyboard, comprising a keyboard body and a sound producing component, wherein the sound producing component is integrated and installed on the keyboard body.

[0006] Beneficial effect: By integrating the sound component on the keyboard body, the keyboard has the function of making sound, ensuring that the user carries the sound component at the same time when carrying the keyboard. At the same time, installing the sound component on the keyboard can save desktop space. Compared with the external speaker solution, there is no need to occupy additional space outside the keyboard, which improves the user's auditory experience.

[0007] In an optional embodiment, the keyboard body includes a key installation area and a peripheral area arranged around the key installation area; the keyboard also includes function keys, and there are multiple function keys, and the multiple function keys are arranged in the key installation area; the pronunciation component is installed in the key installation area.

[0008] Beneficial effect: By installing the sound component in the button installation area, compared with the solution of using an external speaker, the sound component is closer to the user in the space, the sound heard by the user is clearer, and the user's auditory experience is improved.

[0009] In an optional embodiment, the sounding member is provided in plurality, and a spacing is left between any one of the sounding members and an adjacent one of the sounding members.

[0010] Beneficial effect: By providing multiple sounding parts, the user's auditory experience can be further enhanced.

[0011] In an optional embodiment, the sound-generating component includes a shell and a diaphragm, wherein a mounting chamber is provided inside the shell, a sound outlet hole is provided at the upper end of the shell, and the diaphragm is installed inside the mounting chamber and is disposed close to the sound outlet hole.

[0012] Beneficial effect: By opening a sound hole at the upper end of the shell and installing the diaphragm inside the installation chamber and arranging it close to the sound hole, the sound generated when the diaphragm pushes the surrounding air to vibrate can be transmitted to the outside of the keyboard at the sound hole, thereby enhancing the user's auditory experience.

[0013] In an optional embodiment, the sound producing component further includes a voice coil and a magnet installed inside the installation chamber, wherein the voice coil is arranged on a side of the diaphragm away from the upper end of the shell, and alternating current is passed through the voice coil; and the magnet is installed on a side of the voice coil away from the diaphragm.

[0014] Beneficial effect: By installing the magnet on the side of the voice coil away from the diaphragm, when alternating current is passed through the voice coil, the magnetic field generated by the voice coil interacts with the magnetic field generated by the magnet, and the generated force causes the voice coil to vibrate along with the audio current. Since the diaphragm and the voice coil are connected together, when the voice coil and the diaphragm vibrate together, they push the air around the diaphragm to vibrate, thereby generating sound.

[0015] In an optional embodiment, the sound producing component further comprises a magnetic bowl, and the magnetic bowl is mounted on a side of the magnet away from the voice coil.

[0016] In an optional implementation, the voice coil is fixedly connected to the diaphragm.

[0017] In an optional implementation, the diaphragm is spaced apart from an upper end portion of the shell.

[0018] In an optional embodiment, the sounding member is of a button-type design, and the upper end of the shell is close to the diaphragm under the action of an external force, and is away from the diaphragm under the action of an elastic member.

[0019] Beneficial effect: By setting the sound element to a button-type design, specifically, the upper end of the shell is close to the diaphragm under the action of external force, and the upper end of the shell is away from the diaphragm under the action of the elastic member. By leaving a gap between the diaphragm and the upper end of the shell, the phenomenon of poor vibration amplitude of the diaphragm caused by the upper end of the shell colliding with the diaphragm is improved, thereby reducing the influence of the upper end of the shell on the vibration of the diaphragm.

[0020] In an optional embodiment, the keyboard further includes a circuit board, which is installed in the keyboard body and is electrically connected to the electrical components. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0032] In the description of the present application, unless otherwise specified, the term “plurality” means two or more.

[0033] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] In conventional technology, an external speaker is added to the computer to increase the sound structure. However, since the external speaker is an independent unit, if the user forgets the external speaker when carrying the keyboard, it will cause trouble to the user. At the same time, the external speaker will also occupy the already limited desktop space, which is inconvenient for the user to use. Therefore, the utility model integrates the speaker and the keyboard into a design.

[0035] Combine the following Figures 1 to 4 , describing an embodiment of the utility model.

[0036] According to the embodiments of the present utility model, Figures 1 to 4 As shown, a keyboard is provided, comprising a keyboard body and a pronunciation member 2. The pronunciation member 2 is integrated and mounted on the keyboard body.

[0037] The arrangement is as follows: by integrating the sound component 2 on the keyboard body, the keyboard has the function of making sound, ensuring that the user carries the sound component 2 while carrying the keyboard. At the same time, by installing the sound component 2 on the keyboard, it can save desktop space. Compared with the external speaker solution, there is no need to occupy additional space outside the keyboard, which improves the user experience. In addition, by integrating the sound component 2 on the keyboard, the keyboard supplies power to the sound component 2, which can also reduce the number of wiring and make the desktop more concise.

[0038] like Figure 1As shown, the keyboard body includes a key installation area 101 and a peripheral area 102 arranged around the key installation area 101; the keyboard also includes a function key 3, and a plurality of function keys 3 are provided. The plurality of function keys 3 are arranged in the key installation area 101 and are electrically connected to the circuit board 26 inside the keyboard body; the sound component 2 is installed in the key installation area 101.

[0039] By installing the sounding element 2 in the button area, compared with the solution of using an external speaker, the sounding element 2 is closer to the user in space, the sound heard by the user is clearer, and the user's auditory experience is improved.

[0040] It can be explained that the keyboard provided in this embodiment does not specifically limit the number of the pronunciation components 2 .

[0041] As one embodiment, a plurality of the pronunciation members 2 are provided, which may be one, two or more. In this case, a spacing is left between any pronunciation member 2 and an adjacent pronunciation member 2. The key installation area of ​​the keyboard is divided into a main keyboard area, a control key area, a numeric key area and a function key area, and the plurality of pronunciation members 2 are arranged in one or more areas of the main keyboard area, the control key area, the numeric key area and the function key area.

[0042] Such an arrangement, by providing a plurality of sound producing elements 2, facilitates further enhancing the user's auditory experience.

[0043] Preferably, there are two pronunciation members 2, and both are arranged at the main keyboard area. One of the pronunciation members 2 is arranged at the "CapsLock" key, and the other pronunciation member 2 is arranged at the "Enter" key.

[0044] like Figures 2 to 4 As shown, the sounding member 2 includes a housing 21, a diaphragm 22, a voice coil 23, a magnet 24 and a magnetic bowl 25. Specifically, a mounting chamber 211 is provided inside the housing 21, and a sound outlet 212 is provided at the upper end of the housing 21; the diaphragm 22 is installed inside the mounting chamber 211, and the diaphragm 22 is arranged close to the sound outlet 212; the voice coil 23 is arranged on a side of the diaphragm 22 away from the upper end of the housing 21, and an alternating current is passed through the voice coil 23; the magnet 24 is installed on a side of the voice coil 23 away from the diaphragm 22; and the magnetic bowl 25 is installed on a side of the magnet 24 away from the voice coil 23.

[0045] In this arrangement, by installing the magnet 24 on the side of the voice coil 23 away from the diaphragm 22, when alternating current (audio current) is passed through the voice coil 23, the magnetic field generated by the voice coil 23 interacts with the magnetic field generated by the magnet 24, and the generated force causes the voice coil 23 to vibrate along with the audio current. Since the diaphragm 22 is connected to the voice coil 23, when the voice coil 23 vibrates together with the diaphragm 22, the air around the diaphragm 22 is pushed to vibrate, thereby generating sound; at the same time, by opening a sound outlet hole 212 at the upper end of the shell 21, and the diaphragm 22 is installed in the installation chamber 211 and arranged close to the sound outlet hole 212, the sound generated when the diaphragm 22 pushes the surrounding air to vibrate can be transmitted to the outside of the keyboard at the sound outlet hole 212, so that the user can enhance the auditory experience.

[0046] It can be explained that a through hole is opened on the side wall of the housing 21 for the input end and the output end of the voice coil 23 to pass through.

[0047] It can be explained that there is no specific limitation on the material selection of the magnet 24. It can be aluminum nickel cobalt, ferrite and neodymium iron boron. Neodymium iron boron is preferred.

[0048] like Figure 4 As shown, the voice coil 23 is connected and fixed to the diaphragm 22 .

[0049] It can be explained that there is no specific limitation on the connection method between the voice coil 23 and the diaphragm 22. For example, they can be fixed by bonding.

[0050] With such arrangement, the magnetic field generated by the voice coil 23 under the action of alternating current (current) interacts with the magnetic field generated by the magnet 24, that is, it is intuitively manifested as the voice coil 23 vibrating along with the audio current. By connecting and fixing the voice coil 23 to the diaphragm 22, the voice coil 23 and the diaphragm 22 vibrate together, pushing the air around the two to vibrate, thereby producing sound.

[0051] It can be explained that the diaphragm 22 is spaced apart from the upper end of the housing 21 .

[0052] Similarly, the sounding member 2 can be of fixed design, such as Figures 1 to 4 As shown, that is, the sounding member 2 is fixed after installation, and the upper end of the shell 21 and the lower end of the shell 21 are designed as an integral unit.

[0053] Of course, the sounding member 2 can also be designed as a key-type, in which case the upper end of the shell 21 and the lower end of the shell 21 are designed as a separate part, and the upper end of the shell 21 and the lower end of the shell 21 are spaced apart, and the two deformed ends of the elastic member are respectively in contact with the upper end of the shell 21 and the lower end of the shell 21, that is, the upper end of the shell 21 is close to the diaphragm 22 under the action of external force, and at the same time, the distance between the diaphragm 22 and the upper end of the shell 21 is greater than the maximum deformation of the elastic member, so as to avoid the upper end of the shell 21 from contacting the diaphragm 22. After the external force is removed, the upper end of the shell 21 is away from the diaphragm 22 under the action of the elastic member. Further, the selection of the elastic member is not specifically limited. Preferably, the elastic member at least includes a spring, and the deformation direction of the spring is close to the keyboard surface or away from the keyboard surface.

[0054] It can be explained that there is no specific limitation on the number and arrangement of the sound outlet holes 212. For example, a plurality of sound outlet holes are arranged in an array.

[0055] like Figures 1 to 4 As shown, the keyboard further includes a circuit board 26, such as a PCB board. The circuit board 26 is installed in the keyboard body, and the circuit board 26 is electrically connected to the electrical components.

[0056] Specifically, the keyboard body includes an upper cover 103 and a lower cover 104, and the upper cover 103 and the lower cover 104 enclose a accommodating chamber. The circuit board 26 is installed in the accommodating chamber, and the circuit board 26 is installed close to the side of the lower cover 104. At this time, the sound component 2 can be provided with only an upper end, and its upper end is set as a key cap structure, so that the physical structure of the upper end of the shell 21 avoids the diaphragm 22, the voice coil 23, the magnet 24, the magnetic bowl 25 and the elastic component to avoid collision during movement. One end of the elastic component is connected to the upper end of the shell 21, and the other end of the elastic component is fixedly mounted on the circuit board 26.

[0057] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
