[0044] The low-noise key structure and the sound box can effectively solve the problem that key operation easily causes interference to speaker vibration, resulting in noise.
[0045] In the embodiment, the sound box comprises the low-noise key structure and the speaker.
[0046] Referring to Figure 1 and Figure 2 , the low-noise key structure comprises a plurality of key bodies 1, a shell 2, a rotating shaft 3, and a plurality of damping shaft sleeve assemblies 4 corresponding to the key bodies 1 one by one.
[0047] The shell 2 is provided with a mounting hole 201 for mounting the speaker, and a key slot 202 for mounting each key body 1. The rotating shaft 3 is mounted at the key slot 202, and each key body 1 is rotatably connected with the shell 2 through the rotating shaft 3. The damping shaft sleeve assembly 4 is located between the rotating shaft 3 and the corresponding key body 1, and is used to weaken the vibration transmission between the shell 2 and the key body 1.
[0048] The low-noise key structure provided in the embodiment, when the key body 1 is pressed, the key body 1 can rotate around the rotating shaft 3, thereby responding to the pressing operation. Further, the damping shaft sleeve assembly 4 is arranged between the key body 1 and the rotating shaft 3. When the key body 1 is pressed, the vibration on the key body 1 will be absorbed by the damping shaft sleeve assembly 4, and basically cannot be transmitted to the shell 2, and even more cannot interfere with the normal vibration of the speaker.
[0049] Therefore, the low-noise key structure provided in the present application can effectively solve the problem that key operation easily causes interference to speaker vibration, resulting in noise.
[0050] In the embodiment, the key groove 202 is provided with a plurality of partition pieces 203, each of which divides the key groove 202 to form a plurality of key compartments 2021 corresponding to each of the key bodies 1; further, the partition piece 203 is provided with a first shaft passing hole communicating between two adjacent key compartments 2021 and through which the rotating shaft 3 passes, and the rotating shaft 3 passes through each of the first shaft passing holes and further penetrates each of the key compartments 2021.
[0051] By arranging the partition pieces 203 in the key groove 202 to form independent key compartments 2021 and making the rotating shaft 3 penetrate the key compartments 2021, the independence and stability of each key body 1 are maintained, thereby improving the stability and responsiveness of the key operation, and the mutual interference between the key bodies 1 is avoided.
[0052] In the embodiment, a plurality of key compartments 2021 are arranged along the axial direction of the rotating shaft 3, and the key compartments 2021 are provided with a compartment opening in a direction perpendicular to the rotating shaft 3. At least one end of the key body 1 passes through the compartment opening and is arranged in the corresponding key compartment 2021, and the end of the key body 1 extending into the key compartment 2021 is provided with the second shaft passing hole 1011. The damping shaft sleeve assembly 4 fills the gap between the hole wall of the second shaft passing hole 1011 and the peripheral surface of the rotating shaft 3.
[0053] In the embodiment, the end of the key body 1 extending into the key compartment 2021 is provided with two or more rotating parts 101 arranged along the axial direction of the rotating shaft 3 and a cross beam plate 102 connecting the top of each of the rotating parts 101. Each of the rotating parts 101 is provided with the second shaft passing hole 1011. Correspondingly, each of the rotating parts 101 is provided with a shaft sleeve unit 401. Optionally, the number of rotating parts 101 is two, and correspondingly, the number of shaft sleeve units 401 is also two.
[0054] The shaft sleeve unit 401 of the damping shaft sleeve assembly 4 corresponds to each of the rotating parts 101, ensuring the damping effect of each of the rotating parts 101, evenly distributing the damping pressure, and improving the stability and durability of the entire key structure.
[0055] Referring to Figure 3In the embodiment, the shaft sleeve unit 401 has at least a part sleeved on the rotating shaft 3 and inserted into the second shaft hole 1011. Specifically, the shaft sleeve unit 401 includes a barrel portion 4011 sleeved on the rotating shaft 3 and extending into the second shaft hole 1011, and a cap portion 4012 fixed to an end face position of the barrel portion 4011. The diameters of the first shaft hole and the second shaft hole 1011 are both smaller than the diameter of the cap portion 4012, so as to limit the cap portion 4012 from passing through the first shaft hole or the second shaft hole 1011, and thus the key body 1 is in the centered position of the corresponding key compartment 2021.
[0056] In the embodiment, the barrel portion 4011 is in a cylindrical shape, and the cap portion 4012 is in a round cake shape.
[0057] The low-noise key structure further includes a circuit board 5.

[0059] The beam plate 102 at the top of the rotating portion 101 is connected to form an inverted U-shaped structure, which enhances the overall strength of the key body 1. When the outer end of the key body 1 is pressed downward, the beam plate 102 rotates upward and presses the elastic member 6, thereby realizing the pressing operation of the electronic key 501; after the outer end of the key body 1 is released, the elastic member 6 restores the deformation and drives the beam plate 102 to rotate downward and reset.
[0060] In summary, the low-noise key structure and the sound box provided by the embodiment have the following advantages:
[0061] ①Reduce vibration interference: the damping shaft sleeve assembly 4 can absorb the vibration on the key body 1, prevent the vibration from being transmitted to the shell 2 and the loudspeaker, thereby reducing the interference of the key operation on the vibration of the loudspeaker and avoiding the generation of noise;
[0062] ②Improve the operation stability: through the design of the rotating shaft 3 and the damping shaft sleeve assembly 4, the key body 1 can rotate around the rotating shaft 3 when operating, and the damping shaft sleeve assembly 4 effectively absorbs the vibration, reduces the unstable phenomenon of the key caused by the vibration, and improves the stability and responsiveness of the operation;
[0063] ③Maintain the independence of the keys: By setting the separator 203 in the key groove 202 to form an independent key compartment 2021, the independence of each key body 1 is ensured, avoiding mutual interference between the key bodies 1, so that each key body 1 can work independently and accurately;
[0064] ④Improve the key feedback: The use of elastic member 6 provides real key feedback, and users can feel clear pressing and rebounding when operating, improving user experience;
[0065] ⑤Protect electronic components: The elastic member 6 plays a buffering role between the electronic key 501 and the cross beam plate 102, protecting the electronic key 501 and other electronic components on the circuit board 5, prolonging the service life of the sound box.
