Referring to fig. 1, a damping and silencing keyboard includes a keyboard body 1, a keyboard printed circuit board 2, a mechanical shaft 3 and a positioning plate 4; a keyboard printed circuit board 2 and a positioning plate 4 are arranged in the keyboard main body 1; and an acoustical panel 6 is arranged between the keyboard printed circuit board 2 and the positioning plate 4.

The keyboard body 1 is a conventional mechanical keyboard, and the keyboard printed circuit board 2 is a circuit board provided in the keyboard body 1 for executing keyboard commands.

The positioning plate 4 is used for positioning the shaft body of the mechanical shaft.

The sound-deadening plate 6 plays a role in sound deadening when the shaft body of the mechanical shaft 3 is pressed down and rebounded.

The side of the keyboard printed circuit board 2 far away from the sound-deadening plate 6 is provided with a sound-deadening layer 7. The sound-absorbing layer 7 is made of silica gel or sound-absorbing cotton.

The sound-deadening layer 7 improves the shock-absorbing and sound-deadening effects.

Specifically, one side of the sound-absorbing plate 6, which is close to the positioning plate 4, is provided with a bulge 5 which plays a role in shock absorption and limiting.

The bulge 5 is made of the same material as the sound-absorbing plate 6 and is integrally formed. The protrusion 5 serves to facilitate assembly with the positioning plate 4.

Specifically, the protrusion 5 penetrates through the positioning plate 4, and the height of the protrusion 5 is greater than the thickness of the positioning plate 4.

The protrusions 5 penetrate through the positioning plate 4, so that the assembly of the silencing plate 6 and the positioning plate 4 is completed, the positioning plate 4 is connected with the keyboard printed circuit board 2 through screws, and the installation can be completed conveniently and quickly.

Specifically, the sound-absorbing plate 6 is made of a soft material.

In order to ensure the silencing effect of the silencing plate 6, the silencing plate 6 is made of soft material.

Specifically, the sound-absorbing plate 6 is silica gel.

The sound-absorbing plate 6 is made of silica gel, and the softness and the rebound effect of the silica gel are utilized.

Specifically, the number of the protrusions 5 is multiple, and the multiple protrusions 5 are distributed on the upper portion of the sound-absorbing plate 6.

In order to ensure the assembling speed of the sound-absorbing plate 6 and the positioning plate 4 and ensure accurate positioning, the upper part and the lower part of the sound-absorbing plate 6 are both provided with the bulges 5, and the sound-absorbing plate can be assembled by quickly positioning the bulges 5 and the positioning plate 4.

Specifically, the sound-absorbing plate 6 is provided with a hole for the shaft body of the mechanical shaft 3 to pass through.

The mechanical shaft 3 penetrates through the positioning plate 4 to be connected with the keyboard printed circuit board 2, and in order not to influence the original function of the keyboard printed circuit board, a hole through which the mechanical shaft 3 penetrates is formed in the sound attenuation plate 6. The penetration of the mechanical shaft 3 is not influenced, and the effects of noise reduction and shock absorption are also ensured.

Specifically, the thickness of the sound-absorbing plate 6 is 3.5-7 mm.

Because the knocking sense that mechanical keyboard used is liked by many users who use mechanical keyboard, in order not to influence other people and designed acoustical panel 6 in this technique, nevertheless because operational environment is different, and the concentration is different between the people, can choose for use acoustical panel 6 of different thickness to bring different noise cancelling effect.

If the user can use the sound-absorbing board 6 with the thickness of 3.5-4.5mm when the distance between the user and other people is more than 5 meters, the other people beyond 5 meters can only hear 35-45 decibels, and the decibel number of the keyboard without the sound-absorbing board 6 is reduced by half.

When other people are in a range of more than 3 meters and less than 5 meters, the sound-absorbing plate 6 with the thickness of 4.5-5.5mm can be used, and the sound of the membrane keyboard can be achieved.

With a 7mm sound-absorbing panel 6, 10 db can be achieved.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
