Description

Technical Field

[0001] The utility model relates to the technical field of speakers, in particular to a button sleeve and a portable speaker applying the same. Background Art

[0002] A speaker refers to a device that can convert an audio signal into sound. According to the usage scenario, it can be divided into types such as home theater speakers, car speakers, stage speakers, and outdoor portable speakers. As one of the core functions of the product, the function setting or switching of a portable speaker is inseparable from buttons, and buttons with a light-transmitting function can enable users to clearly understand the working state of the speaker.

[0003] Figure 9 A structure of a portable speaker is shown. In this structure, a button board 11' is installed on the top of a housing 10'; more specifically, the button board 11' is provided with a plurality of buttons 110', and both sides of some of the buttons 110' are provided with first lamp beads 111' for emitting light to indicate the working state of the button 110', and some adjacent buttons 110' are both provided with first lamp beads 111'. Based on this structure, when designing a button sleeve in the past, the button sleeve included a relatively flat sheet body and a plurality of rectangular light-shielding sheets. The sheet body and the light-shielding sheets were independent parts and produced separately. The light-shielding sheet was fixed to one side of the sheet body, and the light-shielding sheet was placed between adjacent first lamp beads 111', that is, at the position indicated by L', to separate adjacent first lamp beads 111' and avoid light leakage between different buttons 110'. However, this method not only increases the material cost due to more material quantities, but also, during the assembly process, due to the small volume of the light-shielding sheet, it is easy for the position of the light-shielding sheet to shift because of improper assembly with the sheet body, resulting in one side being bright and the other side being dark, or even one side of the first lamp bead 111' being directly blocked by the light-shielding sheet.

[0004] Therefore, it is still necessary to improve the existing button sleeve structure to solve the problems of cumbersome assembly and poor light-transmitting effect of the existing button sleeve. Summary of the Utility Model

[0031] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0032] As Figures 1 to 8 shown, the embodiment of the present utility model provides a button sleeve 100 for use in cooperation with a button board 101.

[0033] As Figure 3 shown, the button board 101 includes a first board body segment 102. To make the light indications of different function keys independent of each other, as Figure 4 shown, the first board body segment 102 includes a plurality of first units 103 arranged in sequence along its length direction. Each first unit 103 includes a first button 104 and two first light beads 105 distributed on both sides of the first button 104. The first light beads 105 on both sides cooperate to indicate the working state of the first button 104 and provide sufficient light output;

[0034] As Figures 3 to 5 shown, the button sleeve 100 includes a first sleeve body segment; the first sleeve body segment includes:

[0035] A first silicone segment 107 formed by two-color molding. Two-color molding is an existing molding technology, and specifically, secondary injection molding can be used. The first silicone segment 107 includes a light guide main body 108 made of a light guide material and a light isolation strip 109 made of a light isolation material. The light guide material refers to a material that can guide light to pass through, including but not limited to thermosetting silicone, room temperature vulcanized silicone (RTV silicone), and liquid silicone (LSR silicone). The light isolation material refers to a material that cannot guide light to pass through, that is, a material with a light shielding function, including but not limited to silicone rubber, thermoplastic elastomer, and thermosetting rubber. By adding different fillers, the transparency and color can be changed to achieve light isolation or light shielding. The light guide main body 108 is sleeved on the first board body segment 102 and is used to export the light emitted by the first light beads 105; the light isolation strip 109 is located between two adjacent first units 103 and separates the light emitted by two adjacent first light beads 105; and

[0036] The light-shielding ink layer 110 is made of a material that can control the propagation of light. Based on different processes, including but not limited to screen printing ink and UV-curing ink, the light-shielding ink layer 110 is attached to the side of the light guide body 108 facing away from the first plate section 102, which can prevent light from penetrating outward. In addition, first light-transmitting areas 111 corresponding to the multiple first units 103 one by one are formed. The first light-transmitting areas 111 allow the light guided by the light guide body 108 to shine outward. By controlling the position and size of the light-transmitting areas, the light source can be effectively utilized, and it is also convenient for users to distinguish the working states of different buttons.

[0037] Compared with the prior art, the beneficial effects of the present utility model are as follows: The button sleeve 100 is convenient to assemble and has a stable light-transmitting effect. Specifically, by means of two-color molding, the integrated molding of the light guide body 108 and the light-blocking strip 109 is realized. Compared with the situation where the two parts are independent parts in the past, the number of materials can be reduced, and the material cost can be lowered. At the same time, there is no need to assemble and fix the two separated parts together, which avoids the situation of position deviation during their assembly from the source, ensuring the production consistency and light-transmitting stability.

[0038] In some embodiments, such as Figure 3 、 Figure 4 、 Figure 6 and Figure 7 as shown, the first plate section 102 further includes a bare board 112, which is a substrate for providing installation positions for electronic components (such as buttons, lamp beads, etc.). Therefore, each first unit 103 is mounted on the bare board 112; the light guide body 108 is formed with first domes 113 corresponding to the multiple first units 103 one by one. The first domes 113 are spherical or arched and can surround the first units 103; along the thickness direction of the light guide body 108, compared with the light-emitting end of the first lamp bead 105, the bottom of the first dome 113 is closer to the bare board 112, so as to have a light-gathering effect on the light of the first lamp bead 105 and prevent the light of the first lamp bead 105 from directly emitting outward;

[0039] The light-blocking strip 109 is located in the middle of two adjacent first domes 113; compared with the light-emitting end of the first lamp bead 105, the lower end of the light-blocking strip 109 is closer to the bare board 112, and the upper end of the light-blocking strip 109 is located obliquely above the light-emitting end of the first lamp bead 105, so as to form an effective light block on the side of the first lamp bead 105 and prevent light leakage.

[0040] In some embodiments, such as Figures 5 to 7As shown, the bare board 112 and the outer shell 114 are fixedly connected by screws 115; the light shielding strip 109 opposite to the screws 115 is provided with an opening 116 at the lower end for accommodating the screws 115, which can prevent the light shielding strip 109 from being pressed by the screws 115, resulting in local deformation and outward protrusion of the light guide body 108, thus ensuring the shape stability of the light guide body 108.

[0041] In some embodiments, as Figure 3 shown, the first plate body segment 102 further includes a second unit 117; the second unit 117 includes a plurality of second lamp beads 118, and the arrangement direction of the second lamp beads 118 is the same as the width direction of the first plate body segment 108. As an example, the second unit 117 can be used for power display, and the number of the second lamp beads 118 can correspond to the number of power grids, facilitating the user to know the current power situation;

[0042] The first silicone segment 107 further includes a light shielding sleeve 119; the light shielding sleeve 119 is provided with light-transmitting through grooves 120 adapted to the plurality of second lamp beads 118 one by one; the light-shielding ink layer 110 is also formed with second light-transmitting areas 121 corresponding to the plurality of second lamp beads 118 one by one; the second light-transmitting areas 121 allow the light in the light-transmitting through grooves 120 to transmit outwards. Regarding the thickness setting of the light shielding sleeve 119, two methods can be adopted: Method 1, as Figures 3 to 4 shown, the light shielding sleeve 119 has substantially the same thickness as the light guide body 108, that is, the light shielding sleeve 119 does not protrude from the light guide body 108. In this case, an additional light shielding sleeve will be placed on the first plate body segment 102. It should be noted that the light shielding sleeve on the first plate body segment 102 and the light shielding sleeve 119 included in the first silicone segment 107 are basically the same in material and shape, and the only difference lies in the installation position. Therefore, in Method 1, the two light shielding sleeves 119 cooperate to control the light propagation of the second lamp beads 118; Method 2, the thickness of the light shielding sleeve 119 is significantly greater than the thickness of the light guide body 108, that is, the light shielding sleeve 119 protrudes from the light guide body 108 and can cover the second lamp beads 118. Therefore, in Method 2, the thickness of the light shielding sleeve 119 is approximately the sum of the thicknesses of the two light shielding sleeves 119 in Method 1.

[0043] In some embodiments, the light shielding strip 109 and / or the light shielding sleeve 119 are embedded in the light guide body 108, and a sealant gap 122 is left between the outer periphery of the light shielding strip 109 and / or the light shielding sleeve 119 embedded in the light guide body 108 and the light guide body 108. By leaving the gap, it is more convenient for the mold to seal the glue during the secondary injection molding. The glue in the first injection will not be displaced due to the injection pressure during the second injection, further ensuring the molding accuracy and the light transmission effect.

[0044] In some embodiments, the light-shielding ink layer 110 is also attached to the side edge of the light guide body 108, that is, the light-shielding ink layer 110 extends from the upper surface of the light guide body 108 to the side surface, which can prevent light from escaping from the side, further optimizing the light control effect.

[0045] In some embodiments, such as Figure 4 and Figure 8 As shown, when some keys do not require light indication, the key board 101 further includes a second board segment 123 connected to the first board segment 102; the second board segment 123 includes a second key 124, and the key sleeve 100 further includes a second sleeve segment 125 connected to the first sleeve segment; the second sleeve segment 125 is a silicone segment made of light-blocking material and is sleeved on the second board segment 123; the second sleeve segment 125 is formed with a second dome 126; the second dome 126 corresponds to the second key 124 one by one. Therefore, the key sleeve 100 includes both a first sleeve segment that can transmit light and an opaque second sleeve segment 125, providing a more diverse display method and adapting to the usage requirements of different keys. As an example, the key sleeve 100 can be of a three-section type, that is, both the head and the tail are the first sleeve segments, and the middle part is the second sleeve segment 125.

[0046] Such as Figures 1 to 8 As shown, an embodiment of the present invention further provides a portable speaker 1, including the key sleeve 100 of any of the above embodiments. Since the portable speaker 1 includes the key sleeve 100, it at least has the beneficial effects of the key sleeve 100, that is, the key sleeve 100 is convenient to assemble and has a stable light transmission effect. Specifically, by means of two-color molding, the integrated molding of the light guide body 108 and the light-blocking strip 109 is realized. Compared with the conventional situation where both parts are independent parts, the number of materials can be reduced, the material cost can be lowered, and at the same time, there is no need to assemble and fix the two separated parts together, avoiding the situation of position deviation during their assembly from the source, ensuring the production consistency and light transmission stability.

[0047] In some embodiments, such as 1 shown, Figure 3 As shown, the portable speaker 1 further includes a housing 114, a key board 101, and an annular double-sided tape 127. The key board 101 is fixed to the housing 114, and the double-sided tape 127 surrounds the periphery of the key board 101 and the key sleeve 100, which can make the bonding area as large as possible to prevent the edge position of the key sleeve 100 from warping or falling out; one side of the double-sided tape 127 is bonded to the key sleeve 100, and the other side of the double-sided tape 127 is bonded to the key board 101. Fixing with the double-sided tape 127 is convenient for disassembly and assembly and has a low cost.

[0048] In some embodiments, as shown in 1, the outer periphery of the key sleeve 100 fits or presses against the housing 114, which can play a waterproof role.

[0049] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
