[0036] Please refer to Figure 1 , Figure 2 as well as Figure 3 In order to solve the problem that the vibration amplitude of the knob structure is too large to produce tremolo and affect the sound quality of the audio device, the utility model proposes an audio device 1000, including

[0037] A shell 1, a controller and a knob structure, wherein the shell 1 is formed with a support ring 11, and the controller is arranged on the shell 1; the knob structure includes a shock-absorbing gasket 31 and a screw cap 32; the screw cap 32 is connected to the controller, and the screw cap 32 is formed with a buffer groove 321 with a notch facing the support ring 11; the shock-absorbing gasket 31 is arranged on the bottom wall of the buffer groove 321 and elastically abuts against the support ring 11.

[0038] In the technical solution of the present utility model, the vibration generated by the audio device 1000 when working is transmitted to the shell 1, causing the shell 1 to follow the vibration. A shock-absorbing gasket 31 is arranged between the screw cap 32 and the support ring 11, which can effectively buffer the vibration transmitted from the shell 1 to the screw cap 32, thereby reducing the vibration amplitude of the screw cap 32 and the volume of the vibrato generated by the screw cap 32, thereby reducing the influence of the knob structure vibration on the sound quality of the audio device 1000 and improving the user experience.

[0039] Please refer to Figure 4 In one embodiment, there is a receiving gap between the housing 1 and the screw cap 32. When the housing 1 vibrates and squeezes the shock-absorbing gasket 31, the shock-absorbing gasket 31 will be deformed; there is a receiving gap between the housing 1 and the screw cap 32, which can prevent the shock-absorbing gasket 31 from abutting against the peripheral edge of the notch of the buffer groove 321 when the shock-absorbing gasket 31 is squeezed and deformed, thereby preventing the shock-absorbing gasket 31 from continuing to deform; in this way, the deformation amount of the shock-absorbing gasket 31 can reach the maximum value, thereby maximizing the shock-absorbing effect of the shock-absorbing gasket 31, and thus can minimize the vibration amplitude of the screw cap 32 to improve the user experience.

[0040] In one embodiment, the audio device 1000 further includes a silicone panel 4; the silicone panel 4 is disposed around the outer peripheral wall of the support ring 11 and is located in the accommodation gap between the housing 1 and the screw cap 32; a buffer gap is formed between the silicone panel 4 and the screw cap 32. When the screw cap 32 is impacted by an external force, the silicone panel 4 can buffer the impact of the external force, thereby preventing the knob structure from being damaged by the external force; at the same time, when the screw cap 32 shakes and contacts the silicone panel 4, the silicone panel 4 can play a buffering role, preventing the screw cap 32 from generating vibration sound.

[0041] The height of the buffer gap is defined as L, 0.2 mm ≤ L ≤ 0.4 mm. In one embodiment, L = 0.3 mm, so that the deformation of the shock-absorbing gasket 31 can reach the maximum value while the swing amplitude of the screw cap 32 is small.

[0042] It is understandable that the controller can be a control joystick or a potentiometer 2. In one embodiment, the controller is a potentiometer 2, the housing 1 is formed with a through hole 12, the support ring 11 is located at the periphery of the through hole 12, the potentiometer 2 is arranged on the side of the housing 1 facing away from the screw cap 32, and the potentiometer 2 includes at least a portion that is penetrated through the through hole 12 to connect the screw cap 32. The potentiometer 2 is penetrated through the through hole 12 and connected to the screw cap 32, and rotates with the screw cap 32, so as to realize the function of adjusting the audio device 1000 by following the rotation of the screw cap 32.

[0043] Please refer to Figure 6 , Figure 7 as well as Figure 8 In one embodiment, the potentiometer 2 is formed with a chamfered pin 21, and a mounting column 322 is formed on the side of the screw cap 32 facing the housing 1, and a mounting groove 3221 adapted to the chamfered pin 21 is formed on the mounting column 322; the chamfered pin 21 is passed through the through hole 12 and inserted into the mounting groove 3221. The potentiometer 2 is formed with a chamfered pin 21, and the chamfered pin 21 is inserted into the mounting groove 3221 adapted thereto, so that the chamfered pin 21 is prevented from sliding when the screw cap 32 is rotated, so that the potentiometer 2 can accurately adjust the function of the audio device 1000 accordingly as the user rotates the screw cap 32.

[0044] Furthermore, the mounting post 322 is formed with a plurality of ribs 3222 spaced apart along the inner wall of the mounting slot 3221. The ribs 3222 distributed on the inner wall of the mounting slot 3221 can further prevent the chamfered pin 21 from sliding in the mounting slot 3221, so that the potentiometer 2 can more accurately adjust the function of the audio device 1000 accordingly as the user turns the rotary cap 32.

[0045] It is understandable that the support ring 11 may have a semicircular cross-section on the side facing the bottom wall of the buffer groove 321, or may have a plurality of protrusions spaced apart along the circumference of the support ring 11 formed on the side facing the bottom wall of the buffer groove 321. In one embodiment, the cross-section of the support ring 11 on the side facing the bottom wall of the buffer groove 321 is semicircular. This arrangement makes the contact area between the support ring 11 and the bottom wall of the buffer groove 321 smaller, so the friction resistance of the screw cap 32 to the support ring 11 is smaller when rotating, which is convenient for the user to rotate the screw cap 32. Similarly, in another embodiment, a plurality of protrusions spaced apart along the circumference of the support ring 11 are formed on the side facing the bottom wall of the buffer groove 321, which is also to make the contact area between the support ring 11 and the bottom wall of the buffer groove 321 smaller, thereby reducing the friction resistance between the screw cap 32 and the support ring 11, and facilitating the user to rotate the screw cap 32.

[0046] The shock-absorbing gasket 31 may be composed of a layer of polyethylene foam, or may be composed of a layer of ordinary foam and a layer of PET plastic. In one embodiment, the shock-absorbing gasket 31 includes a shock-absorbing layer and a sliding contact layer, the sliding contact layer is arranged on the top of the support ring 11, the shock-absorbing layer is arranged on the side of the sliding contact layer facing away from the support ring 11, and the bottom wall of the buffer groove 321 is arranged on the side of the shock-absorbing layer facing away from the shock-absorbing layer. The material of the shock-absorbing layer is ordinary foam, and the material of the sliding contact layer is PET plastic; ordinary foam can buffer the vibration of the housing 1, and the surface of PET plastic is smooth, so that the friction resistance between the support ring 11 and the screw cap 32 can be reduced, making it convenient for users to twist the screw cap 32.

[0047] Please refer to Figure 5 , define the distance from the support ring 11 to the bottom wall of the buffer groove 321 as L1, the thickness of the shock-absorbing gasket 31 as L2, 0.1mm≤L2-L1≤0.3mm. In one embodiment, L2-L1=0.2mm. Such a configuration allows a small amount of pre-pressure to exist between the shock-absorbing gasket 31 and the support ring 11, thereby preventing the screw cap 32 from shaking and producing vibrations and affecting the sound quality of the audio device 1000; at the same time, it can prevent the shock-absorbing gasket 31 and the support ring 11 from being overly pressurized, resulting in excessive frictional resistance between the shock-absorbing gasket 31 and the support ring 11, making it easier for users to twist the screw cap 32.

[0048] It is understandable that the audio device 1000 includes but is not limited to electronic devices such as power amplifiers, speakers, multimedia consoles, digital mixing consoles, audio sampling cards, synthesizers, and mid- and high-frequency speakers.

[0049] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
