Detailed Description of the Embodiment

[0020] The present utility model will be further described in detail below with reference to the drawings.

[0021] The embodiments described with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as limiting the present application. In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "several" and "multiple" is two or more, unless otherwise specifically defined. In the present application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances. In the present application, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0022] As Figure 1 shown, for the sound absorption and noise reduction structure of the mouse, there are an upper cover 1 and a bottom shell 2 which are matched and buckled on the mouse. There is a button 3 on the upper cover 1, a circuit board 4 is installed on the bottom shell 2, and a trigger 5 is arranged directly below the button 3 on the circuit board 4; the noise reduction structure includes a first sound absorption member 10. The first sound absorption member 10 fills the entire cavity between the upper cover 1 and the bottom shell 2, and there are a number of avoidance grooves 11 on it. The number of avoidance grooves 11 can avoid the stroke path of the button 3, the optical path of the light-emitting component on the circuit board 4, and the functional component 6 on the circuit board 4.

[0023] During use, the contact between the button 3 and the trigger member 5 causes the surrounding air to vibrate and generate noise. The vibration wave is absorbed by the first sound-absorbing member 10 on the periphery, achieving the purpose of eliminating the noise of the mouse button. At the same time, the avoidance groove 11 avoids the deformation displacement (travel path) of the button and the light transmission path (optical path) of the optical mouse, ensuring the normal use of the mouse and not affecting the operating feel of the button.

[0024] As Figures 2 - 3 As shown, further, a scroll wheel 7 is provided on the mouse. The scroll wheel 7 is provided on a rotating shaft 8, and the rotating shaft 8 is mounted on a support 9. A second sound-absorbing member 20 is provided on the periphery and / or beside the rotating shaft 8 on the support 9. The first sound-absorbing member 10 is provided on the periphery of the scroll wheel 7, the rotating shaft 8, the support 9, and the second sound-absorbing member 20.

[0025] During use, the second sound-absorbing member 20 can absorb or relieve the vibration applied by the rotating shaft 8 to the support 9 during the rotation of the scroll wheel 7, achieving the purpose of eliminating the sliding noise of the scroll wheel 7.

[0026] In this embodiment, both the first sound-absorbing member 10 and the second sound-absorbing member 20 are a whole piece of sound-absorbing cotton respectively.

[0027] It can be understood that the first sound-absorbing member 10 and the second sound-absorbing member 20 of the overall structure are convenient for assembly and positioning and do not affect the assembly efficiency of the mouse.

[0028] Figure 4 Shows a specific application embodiment of the above embodiment, which is a silent mouse. The mouse is provided with an upper cover 1, a button 3, a scroll wheel 6, a circuit board 4, and a bottom shell 2. The cavity formed between the upper cover 1 and the bottom shell 2 is filled with the first sound-absorbing member 10 in the above embodiment. The edge of the first sound-absorbing member 10 abuts against the inner walls of the upper cover 1 and the bottom shell 2 or the support members thereon, and presses against the upper end of the circuit board 4.

[0029] In this embodiment, the functional member 6 includes a chip, a battery, a signal receiving member, and a DPI adjusting member. In order to ensure that the heat generated by the chip and the battery is dissipated in time, the first sound-absorbing member 10 is provided with a communicating avoidance groove 11 in the middle of the upper part and the whole lower part of the circuit board 4, and the heat can be directly dissipated out of the mouse bottom shell 2 through this avoidance groove 11.

[0030] The above does not impose any limitation on the technical scope of the present invention. Any modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
