[0035] Please refer to Figure 1 , Figure 2 as well as Figure 3 In order to solve the problem that the user may not be able to observe the key mark 12, the utility model proposes a silicone key structure 1000, including:

[0036] Silicone housing 1, switch assembly and light emitting member 3, silicone housing 1 is formed with a mounting cavity 11; the switch assembly includes a light-transmitting silicone contact 21 and a contact switch 22, the light-transmitting silicone contact 21 is arranged in the mounting cavity 11; the contact switch 22 is connected to silicone housing 1 and abuts against the light-transmitting silicone contact 21; the light emitting member 3 is connected to silicone housing 1 and is located in the mounting cavity 11; the key mark 12 is formed on the side of silicone housing 1 facing away from the light-transmitting silicone contact 21; or, the key mark 12 is formed on the light-transmitting silicone contact 21, the bottom wall of the mounting cavity 11 is formed with a mounting hole, and one end of the light-transmitting silicone contact 21 close to the key mark 12 is inserted into the mounting hole, so that the key mark 12 can be exposed in the silicone housing 1. The user presses on the key mark 12 to squeeze the light-transmitting silicone contact 21, and the light-transmitting silicone contact 21 squeezes the contact switch 22, so that the contact switch 22 is closed and energized, thereby completing the key function.

[0037] In the technical solution of the utility model, the light emitting component 3 emits light, and the light shines on the key mark 12 through the light-transmitting silicone contact 21; since the light-transmitting silicone contact 21 has good light transmission performance, the light emitting component 3 shining on the key mark 12 has high visibility, so it can increase the probability of users observing the key mark 12 on the silicone key structure 1000 in a dark environment, thereby facilitating the use of the user. At the same time, since the light-transmitting silicone contact 21 has good light transmission performance, the use of low-power light emitting components 3 can also achieve the same illumination effect as the high-power light emitting components 3 in other silicone key structure 1000 products; this not only reduces the energy consumption of the light emitting component 3, but also because the price of the same brand of high-power light emitting components 3 on the market is generally higher than the price of low-power light emitting components 3, thus saving the overall cost of the silicone key structure 1000 to a certain extent.

[0038] Specifically, the key mark 12 can be formed on the silicone shell 1, or on the translucent silicone contact 21. In one embodiment, the key mark 12 is formed on the silicone shell 1, so there is no need to punch a hole in the silicone shell 1, so that the overall sealing of the silicone key structure 1000 is better. In another embodiment, the key mark 12 is formed on the translucent silicone contact 21, and a mounting hole is formed on the bottom wall of the mounting cavity 11. One end of the translucent silicone contact 21 close to the key mark 12 is inserted into the mounting hole so that the key mark 12 can be exposed on the silicone shell 1. Since the light transmittance of the translucent silicone contact 21 is better than that of the silicone shell 1, such a setting makes it possible for the light emitted by the light-emitting component 3 to be partially blocked without passing through the silicone shell 1, so that the overall light transmittance of the silicone key structure 1000 is better.

[0039] Those skilled in the art can understand that the button mark 12, the light-transmitting silicone contact 21 and the contact switch 22 may be on the same straight line or not. In one embodiment, the button mark 12 is located in the extension direction of the line between the light-transmitting silicone contact 21 and the contact switch 22. This arrangement enables the user to accurately squeeze the light-transmitting silicone contact 21 when pressing the button mark 12 of the silicone button structure 1000; and the silicone material is relatively soft, so the button mark 12, the light-transmitting silicone contact 21 and the contact switch 22 are arranged on the same straight line so that the deformation caused by squeezing the light-transmitting silicone contact 21 when the user presses the button mark 12 can be transmitted to the contact switch 22, so that the contact switch 22 is closed and energized.

[0040] Similarly, the light-emitting component 3 can be located at any position in the installation cavity 11. In one embodiment, the light-emitting component 3 is located on the side of the light-transmitting silicone contact 21 away from the key mark 12. This arrangement allows most of the light emitted by the light-emitting component 3 to pass through the light-transmitting silicone contact 21 and illuminate the key mark 12, reducing the probability that the light is blocked by the silicone shell 1 and cannot illuminate the key mark 12; thereby increasing the probability that the user can observe the key mark 12 on the silicone key structure 1000 in a dark environment, thereby facilitating user use. Since the light-transmitting silicone contact 21 is made of highly light-transmitting silicone material, the brightness loss of light is low when passing through the light-transmitting silicone contact 21. Therefore, arranging a light-emitting component 3 at any position around the light-transmitting silicone contact 21 can achieve uniform light transmission of the light-transmitting silicone contact 21, so that the brightness of the two sides of the illuminated key mark 12 is consistent, which is convenient for user identification. The light transmittance of the light-transmitting silicone contact 21 is higher than that of the silicone shell 1. The light-transmitting silicone contact 21 can be made of a highly transparent transparent silicone material, and the silicone shell 1 can be made of a milky white silicone material. Thus, when a light-emitting component 3 is arranged on the side of the light-transmitting silicone contact 21 away from the key mark 12, the light emitted by the light-emitting component 3 can pass through the highly transparent light-transmitting silicone contact 21 to reach the other side of the light-transmitting silicone contact 21, so that there is light on both sides of the light-transmitting silicone contact 21, and the light on both sides of the light-transmitting silicone contact 21 is further homogenized by the silicone shell 1 with low transparency, thereby making the light on both sides of the key mark 12 more uniform. Using one light-emitting component 3 can achieve a uniform lighting effect on the outside of the key mark 12, which can reduce the cost of the silicone key structure.

[0041] In one embodiment, the translucent silicone contact 21 includes a base 211 and a center column 212. The base 211 is disposed on the silicone shell 1, the center column 212 is connected to the silicone shell 1 and is disposed corresponding to the button mark 12, the base 211 is formed with a movable groove, and the center column 212 is movably connected to the groove wall of the movable groove; the contact switch 22 abuts against one end of the center column 212 away from the button mark 12. When the user presses the button logo 12, the silicone shell 1 where the button logo 12 is located can squeeze the center column 212, causing the center column 212 to deform; and the center column 212 is limited in the movable groove, so when the center column 212 deforms in a direction perpendicular to the axial direction of the center column 212 and squeezes the groove wall of the movable groove, the groove wall of the movable groove exerts a certain reaction force on the center column 212, which can reduce the deformation of the center column 212 in the direction perpendicular to the axial direction of the center column 212, thereby making the deformation of the center column 212 in the axial direction of the center column 212 larger, thereby increasing the possibility that the center column 212 squeezes the contact switch 22 to close and energize it when the user presses the button logo 12, that is, reducing the possibility of the contact switch 22 failing when the user presses the button logo 12.

[0042] Those skilled in the art can understand that the contact switch 22 and the light-emitting component 3 can be connected to the external circuit through wires or through a PCB board. In one embodiment, the silicone key structure 1000 also includes a PCB board 4, which is connected to the silicone shell 1 and enclosed with the silicone shell 1 to form an installation cavity 11; the contact switch 22 is arranged on the PCB board 4, and the light-emitting component 3 is arranged on the PCB board 4. Such a configuration not only enables the contact switch 22 and the light-emitting component 3 to be connected to the external circuit to realize power supply, but also avoids drilling holes in the silicone shell 1 to affect the sealing performance of the installation cavity 11, and reduces the external dust or water vapor from entering the installation cavity 11 to corrode the internal components of the silicone key structure 1000 or affect the realization of the function of the silicone key structure 1000.

[0043] The light emitting element 3 may be an LED lamp or a small tungsten filament lamp. In one embodiment, the light emitting element 3 is an LED lamp. LED lamps have higher energy efficiency, and the light penetrating ability of the LED lamps is stronger at the same power; at the same time, because silicone is easy to deform at high temperatures, and the heat generated by LED lamps is smaller, the silicone shell 1 and the light-transmitting silicone contacts 21 are less deformed due to high temperatures after long-term use.

[0044] The silicone key structure 1000 includes one or more silicone shells 1, one or more switch components and one or more light-emitting components 3. Figure 1 or Figure 2In one embodiment, the silicone key structure 1000 includes three silicone shells 1, three switch components and three light-emitting components 3; wherein the three silicone shells 1 are connected in sequence, each switch component is connected to a silicone shell 1, and each light-emitting component 3 is connected to a silicone shell 1. Such an arrangement enables the silicone key structure 1000 to control three types of command symbols, so as to be able to perform three types of control on the external circuit.

[0045] In one embodiment, the silicone shell 1 and the translucent silicone contact 21 are integrally formed, so that the sealing performance of the silicone key structure 1000 is better, thereby reducing the entry of external dust or water vapor into the installation cavity 11 and corroding the internal components of the silicone key structure 1000 or affecting the realization of the function of the silicone key structure 1000.

[0046] The utility model also proposes a speaker, which includes a silicone key structure 1000. The specific structure of the silicone key structure 1000 refers to the above embodiment. Since the speaker adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0047] The above are only preferred embodiments of the present invention, and do 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.
