[0037] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Preferred embodiments of the present invention are provided in the drawings. However, the present invention can be implemented in many other different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0038] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0039] In the description of the present invention, unless otherwise defined, all technical and scientific terms used in the present invention have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0040] In the description of the present invention, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0041] like Figure 1-8 As shown, the light-transmitting key structure of the present invention comprises a circuit board 1, a first cover body 2, a second cover body 3, a third cover body 4, a light-transmitting member 5 and a key 6. The circuit board 1 integrates a light source 7 and a trigger 8. The first cover body 2 and the second cover body 3 are connected to the circuit board 1 and are locked by screws. The first cover body 2 and the second cover body 3 are preferably made of ABS plastic. The circular groove 9 of the first cover body 2 is sealed and connected with the raised portion 10 of the third cover body 4. The third cover body 4 is made of transparent silicone. The mounting seat 11 of the third cover body 4 is formed with an inner groove 12. The outer flange of the light-transmitting member 5 is embedded in the inner groove 12 for installation. The light source 7 irradiates the light-transmitting member 5. The actuating portion 13 of the key 6 is sealed and installed with the arc groove 14 of the third cover body 4 by interference fit. The buckle head 15 of the actuating portion 13 is stuck on the end face of the arc groove 14. The buckle head 15 can excite the trigger 8. The light-transmitting key 6 structure of the present invention does not require gluing on the contact plane between the key 6 and the third cover body 4, and can be directly assembled manually, and is easy to disassemble and assemble, simple and easy to operate. The product quality is reliable and stable, the production cost is greatly reduced, and the waterproof and dustproof effect is good.

[0042] Specifically, in this embodiment, the circuit board 1 is a switch circuit board, and the circuit board 1 is connected to the power amplifier module of the speaker host to control the operation of the speaker. A light source 7 and a plurality of triggers 8 are integrated on the circuit board 1. The light source 7 is preferably an LED lamp. The light source 7 remains lit when the speaker is turned on, which increases the atmosphere of the speaker and improves the quality of the speaker. The trigger 8 is a press-contact conductive device. Each trigger 8 corresponds to a different function to control the speaker. For example, in this embodiment, there are four triggers 8, which correspond to the power on / off function, the play / pause function, the volume plus function and the volume minus function. It can be understood that when the trigger 8 of the power on / off function is stimulated for the first time, the speaker enters the power on state, and when the trigger 8 of the power on / off function is stimulated again, the speaker enters the power off state. When the trigger 8 of the play / pause function is stimulated, the speaker switches between the play and pause functions in a cycle. When the trigger 8 of the volume plus function is stimulated, the speaker volume increases. When the trigger 8 of the volume minus function is stimulated, the speaker volume decreases. It should be noted that the number of triggers 8 can be specifically set according to the design function of the speaker, and is not limited here. In addition, the volume plus function and the volume minus function may also integrate a song-cutting function. For example, if the trigger 8 of the volume plus function is long pressed, the speaker will cut the song to the previous song; if the trigger 8 of the volume minus function is long pressed, the speaker will cut the song to the next song.

[0043] Furthermore, in this embodiment, in order to prevent the first cover 2 and the second cover 3 from damaging the circuit board 1 during assembly, a first adhesive 16 is attached to the two mounting sides of the circuit board 1. The first adhesive 16 is preferably an EVA single-sided sealant, and the adhesive side is directly attached to one mounting surface of the circuit board 1, and then the first adhesive 16 is folded toward the other mounting surface of the circuit board 1 for attachment. In this way, the first adhesive 16 has a certain buffering effect, which can prevent the hard cover from damaging the circuit board 1 when assembling the first cover 2 and the second cover 3, thereby avoiding circuit failure.

[0044] Further, in this embodiment, the first cover body 2 and the second cover body 3 are both integrally injection molded by ABS plastic, and the end faces of the first cover body 2 and the second cover body 3 are both shell edges. The first cover body 2 and the second cover body 3 are distributed on both sides of the circuit board 1, and the shell edges abut against the first adhesive 16 and are locked by screws, so that the first cover body 2 and the second cover body 3 are both pressed against the first adhesive 16 and connected. More specifically, the first cover body 2 is divided into four rib frames 17 by four ribs on the first cover body 2, and the connection of the four ribs forms a first through hole 18, and the first through hole 18 passes through the first cover body 2. The four triggers 8 pass through the four rib frames 17 respectively, and the light source 7 is opposite to the first through hole 18, and the light can be transmitted along the first through hole 18. The front end surface of the first cover body 2 is provided with a round groove 9 and a plurality of mounting posts 19, and the round groove 9 and the mounting posts 19 are used to adapt to the sealing installation of the third cover body 4. In this embodiment, the mounting post 19 is a cylinder, and four mounting posts 19 are evenly distributed on the front end surface of the first cover body 2. The serpentine groove 9 is concave from the front end surface to the rear end surface of the first cover body 2, and the groove width of the serpentine groove 9 gradually decreases along the groove depth direction.

[0045] Furthermore, in the present embodiment, the third cover body 4 is made of white light-transmitting silicone in one piece, and a round-shaped protrusion 10 is formed on the rear end face of the third cover body 4. The protrusion 10 protrudes outward from the rear end face of the third cover body 4, and the shape of the protrusion 10 is adapted to the shape of the round-shaped groove 9, that is, the shape of the protrusion 10 gradually decreases from the bottom to the outside. The front end face of the third cover body 4 is provided with a mounting seat 11 and a plurality of mounting holes 20, and the mounting seat 11 is directly opposite to the first through hole 18, and the mounting seat 11 is used to mount the light-transmitting member 5. The light emitted by the light source 7 can reach the mounting seat 11 through the first through hole 18, and the light penetrates the mounting seat 11 and is reflected on the light-transmitting member 5. The shape of the mounting hole 20 is adapted to the shape of the mounting column 19, and the mounting hole 20 is sleeved on the mounting column 19, and the mounting hole 20 and the mounting column 19 are sealed by interference fit, and the protrusion 10 is embedded in the round-shaped groove 9 for sealing installation. Preferably, when the protrusion 10 is embedded in the circular groove 9, a soft sealing glue can be applied to the circular groove 9 to improve the sealing effect. It should be noted that in this embodiment, the interference-fit installation column 19 and the installation hole 20, and the tight assembly of the protrusion 10 embedded in the circular groove 9 can play a good sealing role and meet the waterproof and dustproof requirements of the light-transmitting key structure. Preferably, the front end of the installation column 19 can be provided with an internal threaded hole 21, and the installation column 19 is suitable for installation with the shell 34 of the speaker, so that the light-transmitting key structure can be applied to the speaker product.

[0046] Furthermore, in this embodiment, the light-transmitting member 5 is a decorative member, which can improve the quality of the product and make it more textured. The light-transmitting member 5 can be made of white hard plastic, and the front end surface of the light-transmitting member 5 is formed as a spherical surface. The light-transmitting member 5 is installed on the mounting seat 11, and the spherical edge of the light-transmitting member 5 is flush with the front end surface of the key 6, so that the touch effect and visual effect of the light-transmitting key structure are better. Specifically, the mounting seat 11 is formed as a blind hole extending from the front end surface to the rear end of the third cover body 4, and an inner groove 12 is formed at the bottom of the mounting seat 11. The rear end surface of the light-transmitting member 5 is formed with an outer flange 33, and the outer flange 33 is embedded in the inner groove 12 for tight installation, and the outer flange 33 can be stuck in the inner groove 12. And because the third cover body 4 is a seal made of soft silicone material, when assembling the light-transmitting member 5, the third cover body 4 needs to be expanded and deformed so that the outer flange 33 of the light-transmitting member 5 is inserted into the inner groove 12 of the mounting seat 11. Preferably, in order to make the light of the light-transmitting member 5 more visually appealing, a diffuse reflection portion 22 is provided at the bottom of the light-transmitting member 5, and the diffuse reflection portion 22 is wavy. When the light reaches the bottom of the light-transmitting member 5, the light is diffusely reflected to the entire light-transmitting member 5 under the reflection effect of the diffuse reflection portion 22, so that the light of the entire light-transmitting member 5 is more uniform and soft, and the product quality is further improved.

[0047] Furthermore, in the present embodiment, the button 6 is made of an aluminum alloy material in one piece, which can improve the quality of the product and give it a better texture. Specifically, the button 6 is provided with a second through hole 23, the shape of which is adapted to the light-transmitting member 5, the second through hole 23 is used to assemble the light-transmitting member 5, and the second through hole 23 is fitted with the light-transmitting member 5. The rear end face of the button 6 is formed with a plurality of actuating portions 13 corresponding to the trigger 8, and the four actuating portions 13 are evenly arranged on the rear end face of the button 6, and the front end face of the second cover body 3 is provided with a plurality of arc grooves 14 corresponding to the actuating portions 13, and the actuating portions 13 are buckled in the arc grooves 14, and the actuating portions 13 can excite the trigger 8 by pressing the button 6. More specifically, the cross section of the actuating portion 13 is T-shaped. The actuating portion 13 includes a connecting portion 24 and a buckle 15. The connecting portion 24 extends backward from the rear end surface of the key 6. The connecting portion 24 is arc-shaped. The connecting portion 24 is adapted to the arc groove 14. The connecting portion 24 and the arc groove 14 are sealed by interference fit. The buckle 15 is stuck on the rear end surface of the arc groove 14. The rear end of the buckle 15 is close to the front end of the trigger 8. The buckle 15 is used to trigger the trigger 8. It should be noted that each function of the key 6 corresponds to an actuating portion 13, that is, the mark of the switch function corresponds to one of the actuating portions 13, the mark of the volume plus function corresponds to another of the actuating portions 13, and so on. When the switch function mark of the key 6 is pressed, the corresponding actuating portion 13 moves backward, and the buckle 15 triggers the trigger 8 of the switch function. Similarly, other function marks on the key 6 also work in the same way.

[0048] Furthermore, in this embodiment, the front end surface of the third cover body 4 is provided with a first boss 35, the first boss 35 protrudes forward from the front end of the third cover body 4, and the front end surface of the first boss 35 is formed into a contact plane 36, the contact plane 36 is suitable for fitting and contacting with the rear end surface of the key 6, and there is no need to apply glue or dispense glue on the contact plane 36, so as to avoid the third cover body 4 turning white or the key 6 being uneven, which affects the visual effect and tactile effect of the light-transmitting key structure. In addition, the contact plane 36 without glue does not need to be equipped with a pressure-maintaining fixture to assemble the third cover body 4 and the key 6, which improves production efficiency, and does not cause the entire set of products to be scrapped due to damage to a single component, thereby improving product benefits.

[0049] Furthermore, in this embodiment, a suspension plane 37 is formed at the rear end of the first boss 35, and the rear end face of the button 6 does not contact the suspension plane 37, so as to reduce the resistance of pressing the button 6, and the tactile effect of the product is better, thereby improving the quality of the product. In addition, in order to ensure that the stroke of the buckle head 15 is sufficient to trigger the trigger 8, the distance between the suspension plane 37 and the button 6 of this embodiment is set to be greater than the distance between the buckle head 15 and the trigger 8. In this way, when the button 6 is pressed, the trigger 8 can be triggered before the rear end face of the button 6 reaches the suspension plane 37, and the suspension plane 37 will not form resistance to the button 6. Preferably, in this embodiment, the distance between the suspension plane 37 and the button 6 is 3-5mm±0.5mm, and the distance between the rear end of the buckle head 15 and the front end of the trigger 8 is 1-2mm±0.5mm.

[0050] Furthermore, in this embodiment, in order to facilitate the assembly of the first cover body 2 and the second cover body 3, the rear end face of the first cover body 2 is provided with two symmetrical threaded columns 25, and the front end face of the second cover body 3 is provided with two column sleeves 26 corresponding to the threaded columns 25. The column sleeves 26 are sleeved on the threaded columns 25 and are fastened and connected by screws, and the first cover body 2 and the second cover body 3 are pressed against the first adhesive 16.

[0051] Furthermore, in this embodiment, since there are four triggers 8 and there are four function marks on the corresponding key 6, four arc grooves 14 are also provided, and four actuating parts 13 are also provided. The arc grooves 14 are evenly distributed on the front end surface of the third cover body 4 in a circumferential manner, and the actuating parts 13 are evenly distributed on the rear end surface of the key 6 in a circumferential manner. The position of the function mark on the front end surface of the third cover body 4 forms the pressing part of the key 6, and the pressing part corresponds to the actuating part 13 and is respectively located on the two end surfaces of the third cover body 4. It should be noted that if the corresponding function mark on the key 6 can be set according to the design requirements, such as three or five function marks, then the corresponding trigger 8, actuating part 13 and arc groove 14 are also set accordingly.

[0052] Furthermore, in this embodiment, in order to facilitate accurate assembly, the outer flange 33 of the light-transmitting member 5 is provided with a first fool-proofing portion 27, and the inner groove 12 of the mounting seat 11 is provided with a first fool-proofing groove 28, and the first fool-proofing portion 27 is embedded in the first fool-proofing groove 28 to ensure that the light-transmitting member 5 is accurately assembled with the mounting seat 11. The side of the third cover body 4 is provided with a second fool-proofing portion 29, and the front end surface of the first cover body 2 is also provided with a second fool-proofing groove 30, and the second fool-proofing portion 29 is installed opposite to the second fool-proofing groove 30 to ensure that the third cover body 4 is accurately assembled with the first cover body 2. Preferably, the second fool-proofing portion 29 is provided with a fool-proofing column 31, and the fool-proofing column 31 is embedded in the second fool-proofing groove 30 for installation.

[0053] Furthermore, in this embodiment, in order to ensure the sealing of the assembly of the actuating part 13 and the arc groove 14, the rear end face of the third cover body 4 is also provided with a plurality of glue grooves 32 respectively corresponding to the actuating part 13, and the buckle head 15 is accommodated in the glue groove 32, and the glue is injected into the glue groove 32 to seal the arc groove 14, so as to ensure that the waterproof and dustproof requirements of the product are met. In particular, when there are defects in the secondary assembly or the arc groove 14, because the interference fit between the arc groove 14 and the connecting part 24 is not tight or cannot reach the interference fit, the glue is injected into the glue groove 32 to seal, which does not affect the quality of the product, and can significantly improve the product yield, and the economic benefits are significantly improved.

[0054] Furthermore, in this embodiment, in order to facilitate the buckle head 15 to pass through the arc groove 14 smoothly, the front end surface of the arc groove 14 is provided with a chamfer, and the rear end of the buckle head 15 is provided with a rounded corner. The chamfer facilitates the buckle head 15 to pass through the arc groove 14 for installation, thereby reducing product assembly damage.

[0055] In this embodiment, when assembling the light-transmitting button 6 structure of the present invention, the light-transmitting member 5 is first installed into the mounting seat 11 of the third cover body 4, and the first fool-proofing portion 27 is embedded in the first fool-proofing groove 28; then the actuating portion 13 of the button 6 is pressed into the arc groove 14 of the third cover body 4, and the T-shaped buckle 15 is clamped in the arc groove 14, and the connecting portion 24 and the arc groove 14 are interference fit to achieve sealing, waterproofing and dustproofing; and a combination is obtained.

[0056] At the same time, the first adhesive member 16 is folded in half and pasted on both sides of the circuit board 1, and then the threaded column 25 of the first cover body 2 and the column sleeve 26 of the second cover body 3 are fitted and locked by screws, so that the first cover body 2 and the second cover body 3 are fixed on both sides of the circuit board 1 and the first adhesive member 16 is pressed, the trigger 8 passes through the rib frame 17 of the first cover body 2, and the light source 7 is opposite to the first through hole 18 of the first cover body 2; and the second combination is obtained.

[0057] Finally, the combination 1 and the combination 2 are assembled together, and the four mounting holes 20 of the third cover body 4 are sealed by interference fit with the mounting posts 19 of the second cover body 3, and the second foolproofing portion 29 is aligned with the second foolproofing groove 30, and the assembly of the light-transmitting key 6 structure is completed. It should be noted that when assembling the combination 1, glue can be applied in the glue groove 32 according to the assembly situation, and the glue application will not affect the feel of the key 6.
