When the soft rubber sleeve 30 is installed on the base 10, the boss 333 is inserted into the second through hole 141 and abuts against the support plate 13, and the boss 333 is partially located in the first through hole 131, the annular plate 14 is inserted into the first limiting groove 38, and each stud 16 is respectively inserted into each second limiting groove 342, and the button plate 21 is located in the first through hole 131.

[0046] In this embodiment, the key anti-linkage structure also includes a shading plate 60, which is made of aluminum material and is a ring-shaped structure. The shading plate 60 is located in the key hole 11, and a light-transmitting hole 61 is penetrated in the middle of the shading plate 60. A side of the shading plate 60 away from the button plate 21 is provided with a plurality of marks 62, and a plurality of marks 62 are arranged outside the light-transmitting hole 61. The light-transmitting button 20 also includes a reflector 25 convexly arranged on a side of the button plate 21 away from the hard rubber keyboard 40, and the reflector 25 is located in the middle of the button plate 21. The shading plate 60 is fixed by 3M glue 70. It is mounted on the button plate 21, and the reflector 25 is located in the light-transmitting hole 61. Each mark 62 is set on the shading plate 60 by silk-screen processing. Each mark 62 is set corresponding to each support rod 22. By pressing the mark 62, the corresponding function key 42 can be driven to act to realize the basic key function of the speaker. The reflector 25 only plays a simple role of indicating light transmission. The positioning rod 23 is also set between the reflector 25 and the corresponding mark 62, and also forms a seesaw structure to prevent other function keys 42 from being linked when the reflector 25 is pressed.

[0047] The hard rubber keyboard 40 also includes an LED lamp 43, which is fixed on the control board 41 and electrically connected to the control board 41. The soft rubber cover 30 is also penetrated by a light guide hole 39, and the LED lamp 43 is located in the light guide hole 39. The reflector 25 is arranged corresponding to the light guide hole 39. The light emitted by the LED lamp 43 can enter the light-transmitting button 20 through the light guide hole 39. The control board 41 can drive the LED lamp 43 to emit light of various colors and transmit it to the light-transmitting button 20, so that the light-transmitting button 20 displays light of various colors to indirectly reflect the various working conditions of the speaker.

[0048] When one of the marks 62 on the shading plate 60 is pressed, a seesaw structure is formed between the support rod 22 corresponding to the mark 62 and its adjacent support rod 22 through the middle positioning rod 23. The middle positioning rod 23 is the fulcrum of the seesaw to prevent the adjacent function keys 42 that have not been pressed from being mistakenly triggered and causing linkage. Similarly, a seesaw structure is also formed between other support rods 22 and their adjacent support rods 22 through the middle positioning rod 23. If the light-transmitting button 20 is directly pressed against the control panel 41, the feel will be relatively hard. As a speaker product, sealing treatment is required here. The corresponding soft rubber sleeve 30 can reserve 0.5mm thickness for buffering, which plays a good role in improving the feel. At the same time, when the user mistakenly thinks that the reflector 25 has a function and presses it, each positioning rod 23 as a fulcrum can play a good supporting role without causing the function keys 42 corresponding to other support rods 22 to be triggered, thereby avoiding linkage.

[0049] The light-transmitting button 20 also includes two anti-foolproofing positions 26, which are protruding from the side of the button plate 21 away from the hard rubber keyboard 40. The shading plate 60 is correspondingly provided with two card slots 63, and the two anti-foolproofing positions 26 are respectively clamped in the two card slots 63 to prevent the shading plate 60 from being installed in reverse and affecting the mark 62.
