[0002] A sound card (Sound Card) is also called an audio card (known as a sound effect card in Hong Kong and Taiwan), is the most basic component of a computer multimedia system, and is a hardware for realizing mutual conversion of sound waves and digital signals. The basic function of the sound card is to convert original sound signals from a microphone, a magnetic tape, an optical disc and the like, and output the original sound signals to a headphone, a loudspeaker, a public address system, a recorder and the like, or send out synthesized instrument sound through a musical instrument digital interface (MIDI).

[0003] An external sound card is an audio interface device connected with a computer or a mobile device through a USB interface, has the advantages of convenient use and easy movement, and is particularly suitable for environments requiring better sound quality, such as connection with a notebook computer. The external sound card can provide richer interfaces and better sound quality, supports various platform systems such as Windows, Mac and iOS, and provides various interfaces to meet different recording needs.

[0004] However, the existing external sound card has a single shape and only provides basic functions, so that the user only has auditory enjoyment when using the sound card, and cannot have strong visual effects. In addition, the existing external sound card is basically used by being placed on the surface of an object such as a desktop, which limits the use scene of the external sound card, so that the external sound card cannot be placed at a position convenient for user operation when used in the wild or in an open space or a temporarily set stage, which leads to poor user experience and affects user operation.

[0044] In the embodiment, the side plate and the surface shell 11 have a mounting hole 10b. Specifically, the first side plate 122, the second side plate 123, the third side plate 124 and the surface shell 11 have the mounting hole 10b. The light guide structure includes a first light guide piece 41, which is arranged in the mounting hole 10b. The first light guide piece 41 is arranged on the side of the shell 10, which does not affect the use of the sound card 100, and can also provide a dazzling light effect, thereby providing a visual effect for the user and improving the user experience.

[0045] In the embodiment, the first light guide piece 41 is a light-transmitting adhesive strip, which is arranged in the mounting hole 10b and the portions exposed outside the shell 10 abut against the surface shell 11 and the side plate, respectively. In order to better show the light effect, the first light guide piece 41 has a certain light filtering property, which can filter out part of the light and selectively transmit the emitted light to the outside, so that the light wave acceptable or liked by the user is transmitted, thereby achieving a better effect. In the embodiment, the mounting hole 10b and the portions of the first light guide piece 41 exposed outside are in U-shaped structures.

[0046] In an embodiment, the mounting hole 10b and the first light guide piece 41 can be arranged on only one side of the shell 10, such as the side of the first side plate 122 or the second side plate 123 or the third side plate 124. Alternatively, the mounting hole 10b and the first light guide piece 41 can be arranged on two sides of the shell 10, such as the first side plate 122 and the second side plate 123, or the first side plate 122 and the third side plate 124, or the second side plate 123 and the third side plate 124. The present application does not make specific limitations.

[0047] In other embodiments, the mounting hole 10b can also be arranged between the side plate and the bottom plate 121, or at the middle position of the side plate. In another embodiment, the side plate can also be made of a light-transmitting material as a whole, and the first light guide piece 41 connects the bottom plate 121 and the surface shell 11.

[0048] Please refer to FIGS. 5, 6, 7 and 8. In the embodiment, the first light guide piece 41 includes a main body part 411, a first clamping part 412, a limiting part 413 and an abutting part 414. The main body part 411 abuts against the surface shell 11 and the side plate, and one side thereof is exposed outside the shell 10. Specifically, the outer surface of the main body part 411 exposed outside is flush with the outer surface of the side plate, so that the appearance of the product is more beautiful and neat.

[0049] The first clamping part 412 is arranged on one side of the main body part 411 and clamped with the second clamping part 111 on the surface shell 11, so that the first light guide piece 41 is more firmly mounted with the surface shell 11, and the structure is simple and easy to install.

[0050] The limiting portion 413 is arranged on the side of the main body portion 411 away from the first clamping portion 412, and is adjacent to or abuts against the side plate; the abutting portion 414 is arranged on the other side of the main body portion 411 and abuts against the face shell 11; the abutting portion 414 and the first clamping portion 412 have a deformation portion 415 therebetween, specifically, the deformation portion 415 is a groove, so that when the first clamping portion 412 and the second clamping portion 111 are clamped, there is a certain deformation space, which can improve the assembly efficiency and avoid damage to the parts of the product. The first clamping portion 412, the limiting portion 413 and the abutting portion 414 are all arranged in the containing cavity 10a. The limiting portion 413 is adjacent to or abuts against the side plate and extends from the main body portion 411 towards the bottom plate 121, so that the first light guide 41 can be limited in the containing cavity 10a and cannot be removed from the mounting hole 10b, thereby ensuring the mounting stability of the first light guide 41.

[0051] In order to ensure the connection stability of the first light guide 41 and the shell 10, referring to FIG. 5, the first light guide 41 further comprises a third clamping portion 416, specifically, the third clamping portion 416 is arranged on the side of the abutting portion 414 away from the face shell 11, and the face shell 11 is provided with a fourth clamping portion 112 at a corresponding position, and the third clamping portion 416 and the fourth clamping portion 112 are clamped.

[0052] Referring to FIG. 7, the abutting portion 414 abuts against the face shell 11, and the side of the main body portion 411 and the limiting portion 413 away from the containing cavity 10a is arc-shaped. In order to avoid the light emitted by the light emitting assembly from being emitted to the outside through other positions of the shell 10, and in order to achieve a better light atmosphere effect, in this embodiment, the light guide structure further comprises a first light shielding member 42, which is a baffle and is arranged in the containing cavity 10a and connected with the face shell 11 and abuts against the abutting portion 414 of the first light guide 41, thereby forming a light guide cavity 10c. The light emitted by the light emitting assembly is conducted to the outside of the shell 10 in the light guide cavity 10c through the first light guide 41.

[0053] Specifically, the light-emitting assembly comprises a first light-emitting unit 31 electrically connected with the first circuit board 21, the first light-emitting unit 31 is arranged in the light guide cavity 10c, and the light emitted by the first light-emitting unit 31 is conducted to the outside of the shell 10 through the first light guide member 41. Arranging the first light-emitting unit 31 in the light guide cavity 10c can make the light emitted by the first light-emitting unit 31 directly conducted to the outside of the shell 10 through the first light guide member 41, thereby reducing energy loss.

[0054] In this embodiment, the first light-emitting unit 31 is arranged at the edge portion of the first circuit board 21, the first light-shielding member 42 abuts against the first circuit board 21, and the limiting portion 413 of the first light guide member 41 abuts against the first circuit board 21 at the end away from the first clamping portion 412, and the edge portion of the first circuit board 21, the first light-shielding member 42 and the first light guide member 41 together enclose the light guide cavity 10c, and the light emitted by the first light-emitting unit 31 is conducted to the outside of the shell 10 through the first light guide member 41. Specifically, the first light-emitting unit 31 is a LED lamp bead, which can emit light of various colors. In other embodiments, the first light-emitting unit 31 can also be arranged on the side of the first light-shielding member 42 facing the light guide cavity 10c. The specific arrangement position of the first light-emitting unit 31 is not limited in this application, as long as the light can be conducted out through the first light guide member 41.

[0055] Referring to FIGS. 3 and 7, in this embodiment, the bottom shell 12 is further provided with a limiting plate 13, and the edge portion of the first circuit board 21 is correspondingly provided with a limiting groove 211, and at least part of the limiting plate 13 extends into the limiting groove 211, thereby ensuring correct installation of the first circuit board 21 and avoiding abrasion or damage to other components caused by movement of the first circuit board 21 after installation. In this embodiment, the size of the first circuit board 21 is approximately equal to the size of the bottom plate 121.

[0056] In an embodiment, the edge of the first circuit board 21 can also directly abut against the side plate, and the first light-shielding member 42, the edge portion of the first circuit board 21 and the side plate and the first light guide member 41 together enclose the light guide cavity 10c.

[0057] In an embodiment, the first light-emitting unit 31 can also be arranged at the edge portion of the bottom plate 121 adjacent to the side plate, and the first light-shielding member 42, the edge portion of the bottom plate 121 and the side plate and the first light guide member 41 together enclose the light guide cavity 10c. In a modified embodiment of this embodiment, the limiting portion 413 of the first light guide member 41 can also directly abut against the bottom plate 121, and the first light guide member 41, the bottom plate 121 and the first light-shielding member 42 together enclose the light guide cavity 10c.

[0058] In an embodiment, the abutting portion 414 of the first light guide 41 can not abut against the first light shielding member 42, and the first light emitting unit 31 can be arranged on the face cover 11. The face cover 11, the first light shielding member 42, the first light guide 41, the side plate, and the edge portion of the bottom plate 121 or the first circuit board 21 enclose the light guide cavity 10c. In a modified embodiment of this embodiment, the limiting portion 413 of the first light guide 41 can directly abut against the bottom plate 121. In this case, the face cover 11, the first light shielding member 42, the first light guide 41, and the bottom plate 121 enclose the light guide cavity 10c.

[0059] Referring to FIGS. 3 and 4, in the present embodiment, the control assembly further comprises a function key arranged on the shell 10 and exposed outside the shell 10, and electrically connected with the first circuit board 21, for adjusting the signal amplification degree of the input signal of the sound card 100 and / or the signal intensity of the output signal of the sound card 100, and / or enabling or disabling the mute function of the sound card 100. The function key can be used to better control or adjust the sound card 100, and improve the use efficiency.

[0060] Specifically, the function keys include a button 221, a knob 222, and a slider 223. All function keys are inserted into holes in the faceplate 11 and exposed on the outside of the housing 10, so that users can operate them by pressing, rotating, pushing, pulling, etc. For ease of description and understanding, please refer to Figure 9. In this embodiment, the faceplate 11 is divided into four control areas: a first control area 1a, a second control area 1b, a third control area 1c, and a fourth control area 1d. A knob 222 is located in the first control area 1a, which is situated on the faceplate 11 near the fourth side plate 125. A pusher 223 is located in the second control area 1b, which is situated on the faceplate 11 near the second side plate 123. Some buttons 221 are located in the third control area 1c, which is situated near the third side plate 124 of the faceplate 11. Two buttons 221 are located in the fourth control area 1d, situated at opposite ends of the third control area 1c, and respectively on the faceplate 11 near the first side plate 122 and the fourth side plate 125. Specifically, the knob 222 protrudes the faceplate 11 the highest, followed by the pusher 223, and finally the buttons 221. By arranging the function keys on the four control areas of the faceplate 11 in this way, the function keys on the faceplate 11 are staggered in height, so that they will not interfere with each other during use, thus making it easier for users to distinguish and use them. For example, when you need to rotate the knob 222, you can directly find the highest first control area 1a to operate the knob 222; when you need to push or pull the pusher 223, you can directly find the highest pusher 223 on the second controller on the left to operate it; when you need to press to operate, you can directly find the lowest function key in the third control area 1c or the fourth control area 1d.

[0061] In this embodiment, there are 3 knobs 222, 2 pushers 223, and 13 buttons 221. Nine buttons 221 are arranged in a 3x3 grid in the third control area 1c, and the remaining 4 buttons 221 are arranged in pairs in the two fourth control areas 1d.

[0062] For ease of understanding, each function key will be briefly described in this embodiment.

[0063] The two faders 223 are used to control the volume of the microphone or accompaniment connected to the sound card 100, such as one controlling the volume of the XLR microphone and the other controlling the volume of the Bluetooth input, 3.5mm input and USB-C downstream accompaniment audio.

[0064] One of the knobs 222 is used to control Gain, i.e. the gain of the microphone, such as the gain of the XLR microphone; one knob 222 controls Reverb, i.e. the strength of the reverb effect, which is turned off when the knob 222 is turned to the leftmost position; one knob 222 controls Headphones, i.e. the volume of the output of the "earphone" and "earphone and microphone" interfaces.

[0065] The buttons 221 in the fourth control area 1d are used to control the microphone mute, the accompaniment mute, the microphone power switch, the opening and closing of the Bluetooth accompaniment connection function, etc.

[0066] The buttons 221 in the third control area 1c are used to control the original sound switch (avoidance), the monitoring switch (internal speaker switch), the voice change mode, the noise reduction function, the light show mode (the first light emitting unit 31 light emitting mode), and four self-defined function buttons 221, which can be used to define the light brightness, recording, and clearing recording, etc.

[0067] In order to increase the light show effect and also to enable the buttons 221 to be seen in a dark environment for the convenience of the user, the buttons 221 are light-transmissive, and the light emitting assembly includes a second light emitting unit 32 electrically connected to the first circuit board 21, which is arranged in the accommodating cavity 10a and emits light that is transmitted to the outside of the shell 10 through the function keys. Specifically, the second light emitting unit 32 is an LED lamp bead that can emit light of various colors. The second light emitting unit 32 is arranged on the side of the first circuit board 21 facing the buttons 221. Since the number of buttons 221 is large, the number of second light emitting units 32 is correspondingly arranged to achieve the light-transmissive function of each button 221.

[0068] Please refer to FIG. 3 and FIG. 7. Since the number of buttons 221 and second light emitting units 32 is large and they are arranged close to each other, in order to avoid the light emitted by the second light emitting units 32 affecting the light effect of the adjacent buttons 221, the side of the face shell 11 facing the accommodating cavity 10a is provided with a second light shielding piece 14, which is a baffle. The second light shielding piece 14 and the first circuit board 21 form an installation cavity 10d therebetween, the second light emitting unit 32 is arranged in the installation cavity 10d, and at least part of the function keys is arranged in the installation cavity 10d. In this embodiment, part of the structure of the buttons 221 is arranged between the second light shielding piece 14 and the first circuit board 21, so as to separate them and avoid the second light shielding piece 14 damaging the first circuit board 21. The second light shielding piece 14 is arranged to limit the light emitted by the second light emitting unit 32 in the installation cavity 10d, so that the light emitted by the second light emitting unit 32 can only be transmitted out of the shell 10 through the buttons 221 arranged in the installation cavity 10d.

[0069] The button 221 can emit different colors of light depending on the color of the light emitted by the second light-emitting unit 32. This allows the button 221 to display different colors when pressed, thus serving as an indicator. For example, pressing the button 221 to mute the microphone displays a red light effect, indicating that the microphone is muted. Pressing it again removes the red light effect, indicating that the microphone is unmuted. Due to the large number of buttons 221 and the relationships between them and their corresponding lighting effects, this application will not list them all. In this embodiment, the second light-emitting unit 32 not only enables the buttons 221 to emit different lighting effects, enhancing the lighting effects of the sound card 100, but also serves as a prompt, indicating the status of the corresponding function after the button 221 is pressed.

[0070] Referring to Figures 3 and 4, in this embodiment, the control component further includes a first indicator light 23 and a battery 24 electrically connected to the first circuit board 21; the first indicator light 23 is disposed through the faceplate 11 and is used to display the charge level of the battery 24; the battery 24 is disposed in the receiving cavity 10a. In the sound card 100 provided in this embodiment, the number of first indicator lights 23 is multiple, taking 5 as an example: when the charge level of the battery 24 is greater than 75%, 4 first indicator lights 23 are lit; when the charge level of the battery 24 is less than 75% but greater than or equal to 50%, 3 first indicator lights 23 are lit; when the charge level of the battery 24 is less than 50% but greater than 25%, 2 first indicator lights 23 are lit; when the charge level of the battery 24 is less than or equal to 25%, 1 first indicator light 23 is lit. In other embodiments, other indication forms may also be used, such as dividing the multiple first indicator lights 23 into 4 segments and displaying the current battery charge level of the battery 24 in a bar shape, representing the remaining charge level of the battery 24 at 20%, 40%, 60%, and 80%, respectively; the specific indication form is not specifically limited in this application.

[0071] In order to prevent the light emitted by the first indicator light 23 from affecting the lighting effect of the surrounding buttons 221, a third light shield 16 is provided on the outside of the first indicator light 23. The third light shield 16 is arranged around the first indicator light 23 and abuts against the face shell 11 and the first circuit board 21. The first indicator light 23 is located on the first circuit board 21, thereby ensuring that the light of the first indicator light 23 can only be transmitted to the outside through the face shell 11.

[0072] Since the main function of the pusher 223 is to control the volume, in order to more intuitively show the size of the volume regulated by the pusher 223, the control assembly further includes a second indicator light 25 electrically connected with the first circuit board 21. Specifically, the second indicator light 25 is arranged on the side of the first circuit board 21 facing the face cover 11 and is arranged adjacent to the pusher 223. Specifically, the second indicator light 25 is arranged on the first circuit board 21 between the two pushers 223, and the second indicator light 25 is an LED lamp bead capable of emitting light of various colors. A light-transmitting gap 11a is arranged on the face cover 11 corresponding to the position of the second indicator light 25, so that the light emitted by the second indicator light 25 can be transmitted out of the face cover 11 through the light-transmitting gap 11a. The second indicator light 25 is two, corresponding to the two pushers 223 respectively. The light emitted by the second indicator light 25 can indicate the volume size, such as indicating the strength of the microphone or microphone signal, and using different colors to represent whether it is overloaded.

[0073] In order to make the light emitted by the second indicator light 25 more soft, a second light guide member 15 is arranged in the light-transmitting gap 11a, and the second light guide member 15 is a light-transmitting adhesive strip capable of transmitting relatively soft light, so that the user can be more comfortable when observing. At the same time, in order to avoid the light emitted by the second indicator light 25 affecting the surrounding function keys, a fourth light shielding member 17 is further arranged between the face cover 11 and the first circuit board 21, the fourth light shielding member 17 is arranged around the second indicator light 25, and the second light guide member 15 is arranged on the side of the fourth light shielding member 17 facing the face cover 11, so that the light emitted by the second indicator light 25 is guided out of the face cover 11 through the second light guide member 15.
